Eclipse WebView - eclipse

I would like to open url´s in webview instead of in a webbrowser. I´m no programmer and can´t find a solution. Help would be greatly apreciated. I would like the url to open in a new activity called: activity_webview. Thanks in advance
import android.app.Activity;
import android.content.Intent;
import android.net.Uri;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuInflater;
import android.view.MenuItem;
import android.view.View;
import com.casovi.luxury_new.R;
public class MainCars extends Activity {
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_cars);
}
public void GoKoenigsegg(View view) {
goToUrl("http://www.koenigsegg.com/");
}
public void GoMercedes(View view) {
goToUrl("http://www.mercedes-amg.com/#/home");
}
private void goToUrl(String url) {
Uri uriUrl = Uri.parse(url);
Intent launchBrowser = new Intent(Intent.ACTION_VIEW, uriUrl);
startActivity(launchBrowser);
}
}
}

Make your main activity like this:
first create a webview,
second enable webviewclients,
third enable contentview,
finally load your desired url.
All the best..
public class MainCars extends Activity {
WebView web;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
web = (WebView) findViewById(R.id.webView1);
web = new WebView(this);
web.getSettings().setJavaScriptEnabled(true);
web.loadUrl("http://www.koenigsegg.com/");
web.setWebViewClient(new myWebClient());
web.setWebChromeClient(new WebChromeClient());
setContentView(web);
}

How to use Shared Preference from a Button in another activity?

Im trying to implement SharedPreferences but, since this is all so new to me, Im confused on how to actually do this. I have an activity that contains Two EditTexts and a Button; those EditTtexts are subject and grade, and the button sends it to a fragment activity, which contains a Recyclerview with its cardview etc. I have no trouble getting the input and displaying it in the Recyclerview list. When I try applying the Shared Preferences to save the custom data from the recyclerview, I have no idea where I should input the code.
I tried several tutorials, and I used gson to set a saveData, but I havent been able to call the list, making my app crash.
Activity with the Button
package com.example.repomax;
import android.app.Application;
import android.content.Context;
import android.content.SharedPreferences;
import android.os.Bundle;

import androidx.recyclerview.widget.RecyclerView;
import com.google.gson.Gson;
import com.google.gson.reflect.TypeToken;
import java.lang.reflect.Type;
import java.util.ArrayList;
import java.util.Objects;
public class Binary extends AppCompatDialogFragment {
private PersonAdapter adapter;
private static final String TAG = "Binary Dialog";
public Binary(PersonAdapter adapter) {
this.adapter = adapter;
}
private void onClick(View v) {
if (classtup.getText().toString().isEmpty() || Sectiones.getText().toString().isEmpty()) {
Toast.makeText(getContext(), "Llene todos los campos", Toast.LENGTH_LONG).show();
} else {
ApplicationClass.materias.add(new Lasmaterias(classtup.getText().toString().trim(),
Sectiones.getText().toString().trim()));
adapter.addMaterias(new Lasmaterias(classtup.getText().toString().trim(),
Sectiones.getText().toString().trim()));
Toast.makeText(getContext(), "Clase Registrada", Toast.LENGTH_SHORT).show();

}
}
public void saveData

public OnInputSelected monInputSelected;

RecyclerView.Adapter myAdapter;
TextView Title;
EditText classtup, Sectiones;
Button addud;
Planes planes;
FragmentManager fragmentManager;
#Nullable
#Override
public View onCreateView(LayoutInflater inflater, #Nullable ViewGroup container, Bundle savedInstanceState) {

planes = (Planes) fragmentManager.findFragmentById(R.id.Planes);
addud = view.findViewById(R.id.addud);
addud.setOnClickListener(this::onClick);
return view;
}
}
FragmentActivity with the RecyclerView:
package com.example.repomax;
import android.content.Context;

import android.os.Bundle;
import android.util.Log;
import android.view.LayoutInflater;

import androidx.recyclerview.widget.RecyclerView;
import com.google.gson.Gson;
import java.util.ArrayList;
public class Planes extends Fragment {
private static final String TAG = "Planes fragment";
RecyclerView recyclerView;
RecyclerView.Adapter myAdapter;
RecyclerView.LayoutManager layoutManager;
View view;
Button fab;
public Planes() {
// Required empty public constructor
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
return inflater.inflate(R.layout.fragment_planes, container, false);
}
#Override
public void onViewCreated(#NonNull View view, #Nullable Bundle savedInstanceState) {
super.onViewCreated(view, savedInstanceState);
recyclerView = view.findViewById(R.id.list);
recyclerView.setHasFixedSize(true);
layoutManager = new LinearLayoutManager(this.getActivity());
recyclerView.setLayoutManager(layoutManager);
myAdapter = new PersonAdapter(getContext(), ApplicationClass.materias);
recyclerView.setAdapter(myAdapter);
fab = view.findViewById(R.id.fab);
fab.setOnClickListener(v -> {
Log.d(TAG, "onClick: Abriendo Ventanilla");
Binary dialog = new Binary((PersonAdapter) myAdapter);
dialog.setTargetFragment(Planes.this, 1);
dialog.show(getParentFragmentManager(), "Binary");
});
}
}
And finally the adapter:

import android.view.View;
import android.view.ViewGroup;
import android.widget.TextView;
import androidx.annotation.NonNull;

public class PersonAdapter extends RecyclerView.Adapter<PersonAdapter.ViewHolder> {
private ArrayList<Lasmaterias> materias;
private Context context;
private PersonAdapter adapter;
public PersonAdapter(Context context, ArrayList<Lasmaterias> list) {
this.context = context;
this.materias = list;
}
public void addMaterias(Lasmaterias lasmaterias) {
notifyDataSetChanged();
}
public class ViewHolder extends RecyclerView.ViewHolder {
TextView tvName;
TextView tvGroup;
public ViewHolder(#NonNull View itemView) {
super(itemView);
tvName = itemView.findViewById(R.id.tvName);
tvGroup = itemView.findViewById(R.id.TvPass);
itemView.setOnClickListener(v -> {

}
}
#NonNull
#Override
public PersonAdapter.ViewHolder onCreateViewHolder(#NonNull ViewGroup viewGroup, int i) {
View view = LayoutInflater.from(viewGroup.getContext())
.inflate(R.layout.class_item, viewGroup, false);
return new ViewHolder(view);
}
#Override

#Override
public int getItemCount() {
return materias.size();
}
}

Eclipse doesn't recognize import

I've been trying to import a very simple project I've started on a differnt laptop but for some reson the project now is full of errors.
Eclipse does not recognize imports being made and thus refuse to recognize simple classes as ActionBarActivity and methods like onCreate.
import android.support.v7.app.ActionBarActivity;
import android.support.v7.app.ActionBar;
import android.support.v4.app.Fragment;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
import android.view.ViewGroup;
import android.widget.Button;
import android.widget.Toast;
import android.os.Build;
public class MainActivity extends ActionBarActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
if (savedInstanceState == null) {
getSupportFragmentManager().beginTransaction()
.add(R.id.container, new PlaceholderFragment()).commit();
}
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
/**
* A placeholder fragment containing a simple view.
*/
public static class PlaceholderFragment extends Fragment {
public PlaceholderFragment() {
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.fragment_main, container,
false);
return rootView;
}
#Override
public void onActivityCreated(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onActivityCreated(savedInstanceState);
Button bEnter=(Button) getActivity().findViewById(R.id.bEnter);
Button bSignup=(Button) getActivity().findViewById(R.id.bSignup);
bEnter.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
String toastText="It's Working!!!";
int toastDuration=Toast.LENGTH_SHORT;
Toast toast=Toast.makeText(getActivity(), toastText, toastDuration);
toast.show();
}
});
}
}
}
What am I missing here??
What errors are you getting ?
Trick1:
If the appcompat_v7 project(library) is causing the problem, remove it from the project properties, then perform the following steps.
1) Right click on the main.
2) Hover over Android Tools.
3) Click 'Add Support Library'.
It will download the required library and the clean the project. It should work.
if doesn't work, let me know.
Trick2: Update to the latest Revisions ( Tools and SDKs using SDK manager)
Happy Coding.

Passing User input from mainactivity to a second activity in eclipse

I am bran new to this but I have successfully created a functional button.
I am attempting to pass user input (editText1 on activity_main) to Recipe (my second activity) The first code is my functional button. What am I doing wrong in the second round of code in my attempt at passing information to be displayed on the second activity layout?
package com.example.andrew;
import android.os.Bundle;
import android.app.Activity;
import android.content.Intent;
import android.view.Menu;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
public class MainActivity extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Button b=(Button) findViewById(R.id.button1);
b.setOnClickListener(new OnClickListener() {
public void onClick(View v){
startActivity(new Intent(MainActivity.this, Recipe.class));
}
});
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
}
Second round of code: My attempt at passing information. First activity
package com.example.andrew;
import android.os.Bundle;
import android.app.Activity;
import android.content.Intent;
import android.view.Menu;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
public class MainActivity extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Edit Text et = (Edit Text) findViewById(R.id.editText1);
String theText = et.getText().toString();
Intent i = new Intent(this, Recipe.class);//Recipe is my second class
i.putExtra("text_label", theText);//what is "text_label"? Where should it be?
Button b=(Button) findViewById(R.id.button1);
b.setOnClickListener(new OnClickListener() {
public void onClick(View v){
startActivity(new Intent(MainActivity.this, Recipe.class));
}
});
}
}
And in my second activity I have:
public class Recipe extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.recipe_layout);
Intent i = getIntent();
uriStringi = i.getStringExtra("text_label");//is text_label on actv. 1?
startActivity(i);
}
You are adding data in the intent but while starting the activity you are not using it. Instead creating new intent.
Solution:
In your current Activity, create a new Intent:
Intent i = new Intent(this, Recipe.class);
i.putExtra("text_label", theText);
startActivity(i); // Write this in onClick()
Then in the Recipe, retrieve those values:
Bundle extras = getIntent().getExtras();
if (extras != null) {
String value = extras.getString("text_label");
}

Unfortunately newsample4 stopped in android

1-When i run it,emulator does not allow to show my button.

Implement existing Activity(within there extends/implements) in Fragments (Sherlock)

I have developed an app with some activities. Now I would implenent a Navigation with fragments and Sherlock.
I found a lot of examples, but I don't know how to implement my exiting activities.
Since 3 days I'm looking for an solution...
So it would be great if someone can give me a solution or hint.
Thank you!
These are fragment files:
MainActivity
import android.content.Context;
import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentTransaction;
import com.actionbarsherlock.app.ActionBar;
import com.actionbarsherlock.app.ActionBar.Tab;
import com.actionbarsherlock.app.SherlockFragmentActivity;
public class MainActivity extends SherlockFragmentActivity {
public static Context appContext;
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
//ActionBar gets initiated
ActionBar actionbar = getSupportActionBar();
//Tell the ActionBar we want to use Tabs.
actionbar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);
//initiating both tabs and set text to it.
ActionBar.Tab PlayerTab = actionbar.newTab().setText("Fragment A");
ActionBar.Tab StationsTab = actionbar.newTab().setText("Fragment B");
//create the two fragments we want to use for display content
Fragment PlayerFragment = new AFragment();
Fragment StationsFragment = new BFragment();
//set the Tab listener. Now we can listen for clicks.
PlayerTab.setTabListener(new MyTabsListener(PlayerFragment));
StationsTab.setTabListener(new MyTabsListener(StationsFragment));
//add the two tabs to the actionbar
actionbar.addTab(PlayerTab);
actionbar.addTab(StationsTab);
}
class MyTabsListener implements ActionBar.TabListener {
public Fragment fragment;
public MyTabsListener(Fragment fragment) {
this.fragment = fragment;
}
#Override
public void onTabReselected(Tab tab, FragmentTransaction ft) {
//Toast.makeText(MainActivity.appContext, "Reselected!", Toast.LENGTH_LONG).show();
}
#Override
public void onTabSelected(Tab tab, FragmentTransaction ft) {
ft.replace(R.id.fragment_container, fragment);
}
#Override
public void onTabUnselected(Tab tab, FragmentTransaction ft) {
ft.remove(fragment);
}
}
}
