How can I set one drawable in my layout to use listview?
this is my code and funcion normally but i can't click on item:
public class ListMobileActivity extends Activity {
static final String[] Ristoranti = new String[] { "Osteria Mingot", "Cecchini", "Barrique", "Mediterraneo"};
ListView listView1;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.list);
ListView listView1 = (ListView) findViewById(R.id.listView);
ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, R.layout.list_mobile, R.id.label, Ristoranti);
listView1.setAdapter(adapter);
}
If I extends Activity I can set my drawable, if I extends ListActivity I can Click on the Item but the drawable appear in every item
protected void onItemClick(ListView l, View v, int position, long id) {
//get selected items
// String selectedValue = (String) getListAdapter().getItem(position);
//Toast.makeText(this, selectedValue, Toast.LENGTH_SHORT).show();
}

I'm sorry for this question, but I'm a new in Android developing. I searched in internet, but I don't found any appropriate answer. I have a following code in my custom adapter:
public class ItemsAdapter extends CursorAdapter {
public ItemsAdapter(Context context, Cursor c) {
super(context, c, false);
}
#Override
public void bindView(View view, Context arg1, Cursor cursor) {
ViewHolder viewHolder = (ViewHolder) view.getTag();
viewHolder.title.setText(cursor.getString(cursor
.getColumnIndex("title")));
viewHolder.publishDate.setText(cursor.getString(cursor.getColumnIndex("date_time")));
viewHolder.rssNewsImage.setImageResource(R.drawable.rssnews);
}
#Override
public View newView(Context arg0, Cursor arg1, ViewGroup arg2) {
View view = LayoutInflater.from(mContext).inflate(
R.layout.listview_rssreaderactivity_row, arg2, false);
ViewHolder viewHolder = new ViewHolder();
viewHolder.title = (TextView) view
.findViewById(R.id.tw_title_listview_row_main);
viewHolder.publishDate = (TextView) view.findViewById(R.id.tw_pubDate_listview_row_main);
viewHolder.rssNewsImage = (ImageView) view.findViewById(R.id.imageRssView);
view.setTag(viewHolder);
return view;
}
public class ViewHolder {
TextView title;
TextView publishDate;
ImageView rssNewsImage;
}
}
I want to delete listView item in my custom adapter. Here is my code for click events:
#Override
public boolean onItemLongClick(AdapterView<?> parent, View view,
final int position, long id) {
AlertDialog.Builder itemLongClickdialog = new AlertDialog.Builder(
RssNewsActivity.this);
itemLongClickdialog.setItems(R.array.array_longclick_item,
new OnClickListener() {
#Override
public void onClick(DialogInterface dialog, int which) {
}
});
I can't delete given item.
How to resolve this problem? I will appreciate all answers.
Try This:
DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
// User clicked OK button
ItemsAdapter dba = new ItemsAdapter (yourActivity);
dba.open();
dba.remove(_id);
Log.i("TAAG", "removed: "+_id);
dba.close();
cursor.requery();
listview.getadaper().notifyDataSetChanged();
}
});
This is ListView
<LinearLayout
… >
<ListView
android:id="#+id/listView1" >
</ListView>
</LinearLayout>
and 3 item at the сell
<TextView
android:id="#+id/text1" />
<TextView
android:id="#+id/text2" />
<Button
android:id="#+id/button1"/>
This is code
public class Spisok extends Activity {
private ArrayList<HashMap<String, Object>> Irr;
private static final String Form1 = "form1"; // Форма1
private static final String Form2 = "form2"; // Форма2
private static final String Form3 = "form3"; // Форма3
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_spisok);
setTitle("Irr");
ListView listView = (ListView) findViewById(R.id.listView1);
// создаем массив списков
Irr = new ArrayList<HashMap<String, Object>>();
HashMap<String, Object> hm;
hm = new HashMap<String, Object>();
hm.put(Form1, "1");
hm.put(Form2, "2");
hm.put(Form3, "3");
Irr.add(hm);
hm = new HashMap<String, Object>();
hm.put(Form1, "1");
hm.put(Form2, "2");
hm.put(Form3, "3");
Irr.add(hm);
SimpleAdapter adapter = new SimpleAdapter(this, Irr,
R.layout.list_item, new String[] { Form1, Form2, Form3 },
new int[] { R.id.text1, R.id.text2, R.id.text3 });
listView.setAdapter(adapter);
listView.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<> arg0, View arg1, int arg2,
long arg3) {
Intent intent = new Intent(this, New.class);
intent.putExtra("arraylist", Irr);
startActivity
}
});
and this:
ArrayList<HashMap<String, String>> arl = (ArrayList<HashMap<String, String>>) getIntent().getSerializableExtra("arraylist");
TextView Info = (TextView)findViewById(R.id.text9);
Info.setText("view" +Irr); }
But it is work as wrong. When I use it, I have all ArrayList in the new Activity
intent.putExtra("arraylist", Irr);
I need have only "hm.put(Form3, "3");" (correctly only "3" value) in my NewActivity.
Help me to consist it correctly.
What is your problem ? It is not clear, just i considered that you have a Button in your Spisok Activity . so you need to create a Button object in your noCreate() method as like
Button button1 = (Button)findViewById(R.id.button1);
button1.setOnClickListener(new onClickListener() {
#Override
public void onClick (){
Intent intent = new Intent (this, SecondActivity.class );
startActivity(intent);
}
}
SecondActivity.class is your new Activity . you need to create this Activity class manually using IDE and also need to add this Activity in Manefist file. you can put your TextView text3 SecondActivity's layout file .
You have to put the text of your R.id.text3 into your intent with the method putExtra(String key, String dataToTransfer).
Your OnItemClickListener could look like this:
listView.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<> arg0, View arg1, int position,
long arg3) {
Intent intent = new Intent (this, SecondActivity.class );
intent.putExtra("key for my item 3", "put the text you want to transfer here")
startActivity(intent);
}
});
And in the new Activity you get the transfered data like this:
#Override
public void onCreate(Bundle savedInstanceState){
Intent intent = getIntent();
String transferedText = intent.getStringExtra("key for my item 3");
}
You have a custom ListView ( without coustom listview you cant manage more items in single row), in every row there are two text view and one button. you want if user click the button then open new activity that shows second textview
In your adapter class's getView() method write this code
#Override
public View getView(final int position, View convertView, ViewGroup parent)
{
View row = convertView;
Button button1 = (Button) convertView.findViewById(R.id.button1);
TextView text1 = (TextView)convertView.findViewById(R.id.textview1);
TextView text2 = (TextView)convertView.findViewById(R.id.textview2);
button1.setOnClickListener(new OnClickListener()
{
deleteButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View arg0) {
Intent intent = new Intent (this, SecondActivity.class );
String text = text2.getText().toString();
intent.putExtra("name", "text");
startActivity(intent);
}
});
}
and SecondActivity write this code
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.intent);
Textv = (TextView)findViewById(R.id.tv2);
Intent iin= getIntent();
Bundle b = iin.getExtras();
if(b!=null)
{
String j =(String) b.get("name");
Textv.setText(j);
}
}
Hope this would help you
I'm trying to implement a viewpager with a PagerSlidingTabStrip instead of a TabView. The viewpager has three tabs in which each listview displays a list of events. The three tabs are called Past, Tonight and Future.
I've set up the slider as the github page suggests:
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
View v = inflater.inflate(R.layout.all_events_main_strip, container, false);
// Set up the ViewPager, attaching the adapter and setting up a listener for when the
// user swipes between sections.
pager = (ViewPager) v .findViewById(R.id.pager_main);
tabs = (PagerSlidingTabStrip) v.findViewById(R.id.tabs);
adapter = new MyPagerAdapter(getFragmentManager());
pager.setAdapter(adapter);
tabs.setViewPager(pager);
// Set Present tab as default
pager.setCurrentItem(1);
return v;
}
When the app starts the Main Activity adds for the first time this fragment and everything works great. 3 swipeable tabs with 3 listviews. (c.f. code section)
Here is the problem:
I've noticed that when I press the back button and replace the fragment again, in order to reopen the viewpager, the tab in the middle doesn't show any listview. If I swype left or right the content in the other tabs is loaded and displayed but the Present Tab remains empty.
When I debug the ToNightEvents ListFragment isn't called at all.
Do you guys have any suggestions to solve the problem?
The code:
The code is structured as follows: After the onCreateView I've added an OnDestroyView method to remove the fragment but it didn't work... Then in the fragmentPagerAdapter each page is called as a fragment in the getItem method. Finally at the end of the code you can see the three ListFragment classes in which a listview is populated through an AsyncTask
public class FragmentAllEvents extends Fragment

This would normally work if you were in an Activity, however I guess you are in a Fragment since the code you posted is the method onCreateView(). The problem is that you are trying to use the FragmentManager of the Activity and you should be using the Fragment's FragmentManager. This FragmentManager is not what you need. Try this instead:
adapter = new MyPagerAdapter(getChildFragmentManager());
I think I'm a little bit late but if anyone happens to have the same error here is the solution =)
Q.
The following fixed it for me:
Add an OnBackStackChangedListener to the fragment manager.
In the onBackStackChanged method, get references to both the ViewPager and the PagerSlidingTabStrip (pager and tabs in your example). If the appropriate fragment is currently active, do the following:
pager.invalidate();
tabs.invalidate();
pager.setAdapter(new MyPagerAdapter(getFragmentManager()));
tabs.setViewPager(pager);
I have a listview, I want to pass the Text of the listview to edittext of the another Activity.Can u help?
public class MainActivity extends Activity {
private ListView listView1;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Weather weather_data[] = new Weather[]
{
new Weather(R.drawable.weather_cloudy, "Cloudy"),
new Weather(R.drawable.weather_showers, "Showers"),
new Weather(R.drawable.weather_snow, "Snow"),
new Weather(R.drawable.weather_storm, "Storm"),
new Weather(R.drawable.weather_sunny, "Sunny")
};
WeatherAdapter adapter = new WeatherAdapter(this,
R.layout.listview_item_row, weather_data);
listView1 = (ListView)findViewById(R.id.listView1);
View header = (View)getLayoutInflater().inflate(R.layout.listview_header_row, null);
listView1.addHeaderView(header);
listView1.setAdapter(adapter);
}
When I click the first row,the next activity will show "Cloudy" as in the edittext.
You can create a listview onItemClickListener for ur listview and when user clicks on list item/row u can get the text from that row and u can pass it to next Activity that u r going to call and u r passing data via bundle and Intent like below
listView1.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> arg0, View arg1, int position,
long arg3) {
String text= arg0.getItemAtPosition(position)
Bundle bundle = new Bundle();
bundle.putString("URTEXT", text);
Intent intent = new Intent(MainActivity.this,
NextActivity.class);
intent.putExtras(bundle);
startActivity(intent);
}
});
In Next Activity U can get that data that u passed through bundle like this
Intent intent = getIntent();
String tEXT = intent.getIntExtra("URTEXT", 0);
EditText et= (EditText)findViewById(editTextID);
et.setText(tEXT, TextView.BufferType EDITABLE);
I"m tring it refresh my listview when my sqllite database is change (when delete or update query).
the querys itself works just fine, but it doesn't update the listview layout, only when i"m exiting the acitvity and renter it the liseview is changing.
I tried the methodes:
notifyDataSetChanged()
requery()
the code of the activiy is:
public class ShowListActivity extends ListActivity {
private ItemsDataSource itemsDataSource;
private String source[] = new String[] {MySQLiteHelper.KEY_NAME, MySQLiteHelper.KEY_QUANTITY, MySQLiteHelper.KEY_CHECKED};
private int dest[] = new int[] {R.id.itemTitle, R.id.itemQuantity, R.id.itemCheck};
public void goBackMethod(View view) {
Intent intent = new Intent(this, MainScreen.class);
startActivity(intent);
}
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
try {
setContentView(R.layout.activity_show_list);
} catch (Exception e) {
e.getMessage();
}
ApplicationController applicationController = (ApplicationController)getApplicationContext();
itemsDataSource = applicationController.itemsDataSource;
final Cursor mCursor = itemsDataSource.getAllItems();
startManagingCursor(mCursor);
CustomCursorAdapter adapter = new CustomCursorAdapter(this, mCursor);
adapter.notifyDataSetChanged();
setListAdapter(adapter);
ListView listView = getListView();
listView.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
selectAction(id);
}
});
}
private void selectAction(final long position) {
Builder builder = new AlertDialog.Builder(this);
builder.setTitle("בחר פעולה");
builder
.setMessage("בחר בפעולה שברצונך לבצע:");
builder.setPositiveButton("עדכן פריט קניה",
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
//do update
}
});
builder.setNeutralButton("מחק פריט קניה",
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
itemsDataSource.deleteItem(position);
Toast toast = Toast.makeText(getBaseContext(), "הפריט הנבחר נמחק בהצלחה", Toast.LENGTH_SHORT);
toast.show();
}
});
builder.setNegativeButton("חזור לרשימת הקניות",
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
dialog.cancel();
}
});
AlertDialog alertDialog = builder.create();
alertDialog.show();
}
}
the code of the customadapter is:
public class CustomCursorAdapter extends CursorAdapter implements Adapter {
private Cursor mCursor;
private Context mContext;
private final LayoutInflater mInflater;
public CustomCursorAdapter(Context context, Cursor c) {
super(context, c);
mInflater=LayoutInflater.from(context);
mContext=context;
}
#Override
public void bindView(View view, Context context, Cursor cursor) {
TextView itemTitle= (TextView)view.findViewById(R.id.itemTitle);
itemTitle.setText(cursor.getString(cursor.getColumnIndex(MySQLiteHelper.KEY_NAME)));
TextView itemQuantity = (TextView)view.findViewById(R.id.itemQuantity);
itemQuantity.setText(cursor.getString(cursor.getColumnIndex(MySQLiteHelper.KEY_QUANTITY)));
CheckBox itemCheck = (CheckBox) view.findViewById(R.id.itemCheck);
itemCheck.setChecked(cursor.getInt(cursor.getColumnIndex(MySQLiteHelper.KEY_CHECKED))==1);
}
#Override
public View newView(Context context, Cursor cursor, ViewGroup parent) {
final View view=mInflater.inflate(R.layout.listview_item_row, parent, false);
TextView itemTitle= (TextView)view.findViewById(R.id.itemTitle);
itemTitle.setText(cursor.getString(cursor.getColumnIndex(MySQLiteHelper.KEY_NAME)));
TextView itemQuantity = (TextView)view.findViewById(R.id.itemQuantity);
itemQuantity.setText(cursor.getString(cursor.getColumnIndex(MySQLiteHelper.KEY_QUANTITY)));
CheckBox itemCheck = (CheckBox) view.findViewById(R.id.itemCheck);
itemCheck.setChecked(cursor.getInt(cursor.getColumnIndex(MySQLiteHelper.KEY_CHECKED))==1);
return view;
}
}
in your code you have not added your adapter class. I am sure that you will be adding the data in list view from an array list.
So in the time of updating the list view by adding or removing a data to the list view, first either add or remove the data from your array list and the call as follows
listView.invalidateViews();
then call your set Adapter method
