Where would I get callback for the positive/negetive - Yes/No buttons for this dialog?
Also, how can I customize the text on this Dialog?
Instead of this app I want to insert my App name. And I don't want the part that says Use Google's location service.......etc.etc.
Here is the answer.
protected static final int REQUEST_CHECK_SETTINGS = 0x1;
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
switch (requestCode) {
case REQUEST_CHECK_SETTINGS:
switch (resultCode) {
case Activity.RESULT_OK:
// All required changes were successfully made
break;
case Activity.RESULT_CANCELED:
// The user was asked to change settings, but chose not to
break;
default:
break;
}
break;
}
}

I need some help with MVVM architecture.
I have a RecyclerView that receives LiveData and display it perfectly, however, my recyclerView requires another source of Data to customize colors and backgrounds of TextViews. for now I'm using a public list declared in the Mainactivity, But I've read that it's not a good practice.
is it possible to perform a non-live request to database from inside RecyclerView, in order to replace the public list ? if not I would really like some suggestions.
here is my onBindViewHolder:
#Override
public void onBindViewHolder(#NonNull ResultRecyclerViewAdapter.ResultHolder holder, int position) {
Results currentResult = results.get(position);
holder.ston1.setText(currentResult.getSton1());
holder.ston2.setText(String.valueOf(currentResult.getSton2()));
holder.ston1.setBackgroundColor(0xFF12FF45);
holder.ston2.setBackgroundColor(0xFF12FF45);
holder.ston1.getBackground().setAlpha(100);
holder.ston2.getBackground().setAlpha(100);
for (Ston ston: MainActivity.Stons){
if (currentResult.getStonCode().equals(ston.getStonCode()) && currentResult.getStonType().equals(ston.getStonType())){
switch (ston.getStonSelected()) {
case "WADS":
holder.ston1.getBackground().setAlpha(255);
break;
case "WQAS":
holder.ston2.getBackground().setAlpha(255);
break;
}
break;
}
}
holder.ston1.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Boolean found = false;
for (Ston ston: MainActivity.Stons){
if (currentResult.getStonCode().equals(ston.getStonCode())){
found = true;
break;
}
}
if (!found) {
holder.ston1.getBackground().setAlpha(255);
MainActivity.Stons.add(new Stons(currentResult.getStonCode(),"WADS",
currentResult.getStonType()));
}
else {
for (Ston ston : MainActivity.Stons) {
if (currentResult.getStonCode().equals(ston.getStonCode()) && ston.getStonSelected().equals("WADS") &&
ston.getStonType().equals(currentResult.getStonType())){
MainActivity.Stons.remove(ston);
holder.ston1.getBackground().setAlpha(100);
break;
}
}
}
}
});
holder.ston2.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Boolean found = false;
for (Ston ston: MainActivity.Stons){
if (currentResult.getStonCode().equals(ston.getStonCode())){
found = true;
break;
}
}
if (!found) {
holder.ston2.getBackground().setAlpha(255);
MainActivity.Stons.add(new Stons(currentResult.getStonCode(),"WQAS",
currentResult.getStonType()));
}
else {
for (Ston ston : MainActivity.Stons) {
if (currentResult.getStonCode().equals(ston.getStonCode()) && ston.getStonSelected().equals("WQAS") &&
ston.getStonType().equals(currentResult.getStonType())){
MainActivity.Stons.remove(ston);
holder.ston2.getBackground().setAlpha(100);
break;
}
}
}
}
});
One option that I see is to create new type specifically for your recyclerview adapter that will hold both Results object and information that you use for background alpha. So in your activity (or fragment) when livedata observer is triggered you don't directly pass it to adapter, but first create collection of objects of your new type, and then pass it to adapter. And I strongly suggest you to use Kotlin if possible, there you can use collection mapping to map collection from the db to your new type's collection.
My main activity opens a dialog fragment with 2 items in a listview. Clicking either one starts a new Activity. Unless I use getActivity().startActivityForResult() my code for onActivityResult never runs. Everything I've read here discourages using getActivity().startActivityForResult() and says just use startActivityForResult(). Normally I'd say "doesn't matter, code works" but its driving me nuts why its discouraged so much and why it won't work without getActivity(). I've been pouring over documentation and can't find an answer, help me stackoverflow, you're my only hope.
My onActivityResult() code located in my main activity (Landing.class):
#Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
String s = "";
Session current = new Session();
Gson gson = new Gson();
if (resultCode == RESULT_OK) {
if (requestCode == 1) {
s = data.getStringExtra("SESSION_JSON");
current = gson.fromJson(s, Session.class);
}
}
sessions.add(current);
adapter.notifyDataSetChanged();
}
Code that calls startActivityForResult() located in my DialogFragment class:
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
dismiss();
if (position == 0) {
Intent intent = new Intent(getActivity(), ActiveSessionActivity.class);
getActivity().startActivityForResult(intent, 1);
}
}
Code in ActiveSessionActivity class that should be returning the result to onActivityResult() in my main activity:
public void saveSession(View v) {
Session session;
Gson gson = new Gson();
String json = gson.toJson(session);
Intent intent = new Intent();
intent.putExtra("SESSION_JSON", json);
setResult(RESULT_OK, intent);
finish();
}
Android DialogFragments are still fragments, as such calling startActivityForResult from your dialog will actually be getting the result in the dialog. If you were to implement onActivityResult in your DialogFragment you'll get your callback. The reason getActivity().startActivityForResult() is discouraged is because the dialog has no control of the activity and it might not be attached anymore. Try...
if (getActivity() != null && !isDetached() && !isRemoving()) {
getActivity().startActivityForResult(...);
}
I have a question about an error I get in Eclipse.
Eclipse says "The nested type DisplayMessageActivity cannot hide an enclosing type"
This is my script:
package com.example.warzonegaming;
public class DisplayMessageActivity {
public class DisplayMessageActivity extends Activity {
#SuppressLint("NewApi")
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// Get the message from the intent
Intent intent = getIntent();
String message = intent.getStringExtra(MainActivity.EXTRA_MESSAGE);
// Create the text view
TextView textView = new TextView(this);
textView.setTextSize(40);
textView.setText(message);
// Set the text view as the activity layout
setContentView(textView);
// Make sure we're running on Honeycomb or higher to use ActionBar APIs
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB) {
// Show the Up button in the action bar.
getActionBar().setDisplayHomeAsUpEnabled(true);
}
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case android.R.id.home:
NavUtils.navigateUpFromSameTask(this);
return true;
}
return super.onOptionsItemSelected(item);
}
}
}
Does someone knows an fix for this, because I can't go further now.
Regards

I have been looking in thousand posts for this, but I do not find how to solve my problem.
I have an ImageView. When the user clicks on this ImageView, a DialogFragment is displayed, and the user can choose between taking a new picture with the camera, or selecting a picture from the gallery. Until here everything works fine.
The problem is, that the picture selected by the user, should replace the current one in the ImageView, but this bit, is the one that is not working, because the onActivityResult() function that executes this code is not being executed, so the image in the ImageView always remains the same. I would appreciate any help, because I do not see or understand, why this code is not being executed.
I am getting a warning in the LogCat right after the user selects the image:
05-07 12:17:11.542: I/ActivityManager(59): Displayed activity com.android.gallery/com.android.camera.ImageGallery: 935 ms (total 935 ms)

imageLoader = (ImageView) findViewById(R.id.f_imageLoader);
imageLoader.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {

imageLoaderDialog.show(getSupportFragmentManager(), "imageLoaderDialog");
}

ImageLoaderDialog.java:
//Dialog for choosing between new camera image or gallery image.
public class ImageLoaderDialog extends android.support.v4.app.DialogFragment {
private ImageView targetImageView = null;
final int TAKE_PICTURE = 0;
final int PICK_PHOTO = 1;
public ImageLoaderDialog (View view) {
targetImageView = (ImageView) view;
}
#Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
builder.setTitle("Selecciona");
final String[] imageSources = getResources().getStringArray(R.array.imageSources);
builder.setItems(imageSources, new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int item) {
switch(item) {
case TAKE_PICTURE:
Intent takePicture = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(takePicture, TAKE_PICTURE);
break;
case PICK_PHOTO:
Intent pickPhoto = new Intent(Intent.ACTION_PICK, android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
startActivityForResult(pickPhoto, PICK_PHOTO);
break;
}
}
});
return builder.create();
}
//Set image to user's selected image.
public void onActivityResult(int requestCode, int resultCode, Intent intent) {
super.onActivityResult(requestCode, resultCode, intent);
if (resultCode == android.app.Activity.RESULT_OK) {
Uri selectedImage = intent.getData();
Log.i("IMAGEN", ""+selectedImage);
targetImageView.setImageURI(selectedImage);
}
}
}
Any help would be very appreciated.
The hosting activity overrode the onActivityResult but did not make a call to super.onActivityResult for unhandled result codes. Apparently even though the fragment is the one making the startActivityForResult call, the activity gets the first shot at handling the result. This makes sense when you consider the modularity of fragments. Once I implemented super.onActivityResult for all unhandled results, the fragment got a shot at handling the result.Try This:
getActivity().onActivityResult(requestCode, resultCode, intent);
ImageView Iv2 = (ImageView)findViewById(R.id.imageView2);
textId++;
String imgId = "full_" + textId;
int Ivid = getResources().getIdentifier(imgId, "drawable", getPackageName());
Iv2.setImageResource(Ivid);
Iv2.setOnTouchListener(new OnTouchListener() {
#Override
public boolean onTouch(View v, MotionEvent event) {
// TODO Auto-generated method stub
clapping = MediaPlayer.create(textBasedquiz.this, R.raw.applause);
clapping.start();
Intent intent = getIntent();
overridePendingTransition(0, 0);
intent.addFlags(Intent.FLAG_ACTIVITY_NO_ANIMATION);
finish();
overridePendingTransition(0, 0);
startActivity(intent);
return true;
}
});
*Basically im trying to build an quiz for kids and in this im selecting images randomly i want to restart same code after user has touch on right image so he/she can get another question , but activity must start after sound has been played Please Guys help me i really need your valued comments *
You can setResult and go to activity from where you have called your this activity. Pass the value along and based on result of value received, call the saem activity passing new value that you just got from the same activity.
static int RESULT_OK = 100;
STATIC INT RESULT_CANCEL = 110;
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
switch(resultCode) {
case RESULT_OK:
// Get flags/values from intent Intent.FLAG_ACTIVITY_NO_ANIMATION
// Create new activity setting the intent to call
// and pass the values
startActivity(intent);
break;
}
}
I think this will be more straight forward rather than calling same Activity from itself only.
