Карты Активность в навигационном ящике

Question

У меня проблема с отображением активности карт в навигационном ящике. Вот мой код.

MainActivity.java (Это моя панель навигации)

public class MainActivity extends ActionBarActivity { 

private ListView mDrawerList; 
private DrawerLayout mDrawerLayout; 
private ArrayAdapter<String> mAdapter; 
private ActionBarDrawerToggle mDrawerToggle; 
private String mActivityTitle; 

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_main); 

    mDrawerList = (ListView)findViewById(R.id.navList); 
    mDrawerLayout = (DrawerLayout)findViewById(R.id.drawer_layout); 
    mActivityTitle = getTitle().toString(); 

    addDrawerItems(); 
    setupDrawer(); 

    getSupportActionBar().setDisplayHomeAsUpEnabled(true); 
    getSupportActionBar().setHomeButtonEnabled(true); 
} 

private void addDrawerItems() { 
    String[] Array = { "Driver Details", "Track Me", "Contact", "Report Driver", "Call For Emergency", "Rate Taxi", "Favorites", "Top Drivers", "Security Tips" }; 
    mAdapter = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, Array); 
    mDrawerList.setAdapter(mAdapter); 

    mDrawerList.setOnItemClickListener(new AdapterView.OnItemClickListener() { 
     @Override 
     public void onItemClick(AdapterView<?> parent, View view, int position, long id) { 
      switch (position){ 
       case 0: 
        startActivity(new Intent(getBaseContext(), DriverDetails.class)); 
        break; 
       case 1: 
        startActivity(new Intent(getBaseContext(), MapsActivity.class)); 
        break; 
       case 2: 
        Toast.makeText(MainActivity.this, "Contact", Toast.LENGTH_SHORT).show(); 
        break; 
       case 3: 
        Toast.makeText(MainActivity.this, "Report Driver", Toast.LENGTH_SHORT).show(); 
        break; 
       case 4: 
        Toast.makeText(MainActivity.this, "Call for Emergency", Toast.LENGTH_SHORT).show(); 
        break; 
       case 5: 
        Toast.makeText(MainActivity.this, "Rate Taxi", Toast.LENGTH_SHORT).show(); 
        break; 
       case 6: 
        Toast.makeText(MainActivity.this, "Favorites", Toast.LENGTH_SHORT).show(); 
        break; 
       case 7: 
        Toast.makeText(MainActivity.this, "Top Drivers", Toast.LENGTH_SHORT).show(); 
        break; 
       case 8: 
        Toast.makeText(MainActivity.this, "Security Tips", Toast.LENGTH_SHORT).show(); 
        break; 
      } 
     } 
    }); 
} 

private void setupDrawer() { 
    mDrawerToggle = new ActionBarDrawerToggle(this, mDrawerLayout, R.string.drawer_open, R.string.drawer_close) { 

     /** Called when a drawer has settled in a completely open state. */ 
     public void onDrawerOpened(View drawerView) { 
      super.onDrawerOpened(drawerView); 
      getSupportActionBar().setTitle("TaxiSafe"); 
      invalidateOptionsMenu(); // creates call to onPrepareOptionsMenu() 
     } 

     /** Called when a drawer has settled in a completely closed state. */ 
     public void onDrawerClosed(View view) { 
      super.onDrawerClosed(view); 
      getSupportActionBar().setTitle(mActivityTitle); 
      invalidateOptionsMenu(); // creates call to onPrepareOptionsMenu() 
     } 
    }; 

    mDrawerToggle.setDrawerIndicatorEnabled(true); 
    mDrawerLayout.setDrawerListener(mDrawerToggle); 
} 

@Override 
protected void onPostCreate(Bundle savedInstanceState) { 
    super.onPostCreate(savedInstanceState); 
    // Sync the toggle state after onRestoreInstanceState has occurred. 
    mDrawerToggle.syncState(); 
} 

@Override 
public void onConfigurationChanged(Configuration newConfig) { 
    super.onConfigurationChanged(newConfig); 
    mDrawerToggle.onConfigurationChanged(newConfig); 
} 

@Override 
public boolean onCreateOptionsMenu(Menu menu) { 
    // Inflate the menu; this adds items to the action bar if it is present. 
    getMenuInflater().inflate(R.menu.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(); 

    //noinspection SimplifiableIfStatement 
    if (id == R.id.action_settings) { 
     return true; 
    } 

    // Activate the navigation drawer toggle 
    if (mDrawerToggle.onOptionsItemSelected(item)) { 
     return true; 
    } 

    return super.onOptionsItemSelected(item); 
} 
} 

MapsActivity.java

public class MapsActivity extends FragmentActivity { 

private GoogleMap mMap; // Might be null if Google Play services APK is not available. 

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_maps); 
    setUpMapIfNeeded(); 


} 

@Override 
protected void onResume() { 
    super.onResume(); 
    setUpMapIfNeeded(); 
} 

private void setUpMapIfNeeded() { 
    // Do a null check to confirm that we have not already instantiated the map. 
    if (mMap == null) { 
     // Try to obtain the map from the SupportMapFragment. 
     mMap = ((SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map)) 
       .getMap(); 
     // Check if we were successful in obtaining the map. 
     if (mMap != null) { 
      setUpMap(); 
     } 
    } 
} 

private void setUpMap() { 
    mMap.addMarker(new MarkerOptions().position(new LatLng(0, 0)).title("Marker")); 
} 
}

Я прекрасно работать в отдельном проекте при создании карты Google. Когда я добавляю его в свой проект, он всегда останавливается каждый раз, когда я выбираю трек в своем навигационном ящике. Я не знаю, что не так с моим кодом или чего не хватает в моем коде.

Answer 1

Расширьте Mapfragemnt в Fragemnt .. Не как FragmentActivity ...

Тогда в вашей основной деятельности, вызовите следующий код ...

FragmentManager fragmentManager = getSupportFragmentManager(); 
      FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction(); 
      fragmentTransaction.replace(R.id.content_frame, MapActivity()); 
      fragmentTransaction.commit(); 

R.id.content_frame является framelayout внутри ваш MainActivity.xml ...

Я не знаю, что это идентификатор вы дали это framelayout так, которого не вывешивает MainActivity.xml

Answer 2

Я просто чистые: мой проект и построить его снова. то он работает, когда я запускаю его снова. Я не знаю, что произойдет. :) Спасибо за ваши комментарии. :)
