Landscape-Modus kann nicht zwei Fragmente zeigen

Question

Ich erstelle nur eine App mit Listview und Webview. Der Portrait-Modus funktioniert einwandfrei. Aber wenn ich das Telefon im Querformat (Android Studio Emulator) drehen, hat es unbekannt Buffer

04-28 14: 07: 42,822 2202-2216/shiweichen22gmail.q1 E/Oberfläche: getSlotFromBufferLocked: unbekannt Puffer das Fragment zeigt mit list-view und rechte Teil zeigt das Fragment mit web-view 0xab7926c0

ich nach links Teil wollen. Aber es zeigt nur das Fragment mit list-view. ich bereits android Ressourcenverzeichnis mit Querformat-Layout erstellen (in Android nicht gefunden, kann nur in dem Projekt gefunden)

Hier ist mein Code Portrait.xml

Answer 1

Warum Sie zwei registrieren außer Kraft setzen Aktivität in Manifest? Der Name beider Layout-Dateien (Land + Port) muss identisch sein.

Auf diese Weise wählt Ihre Aktivität aus, welches Layout automatisch ausgewählt wird.

Wichtig: - Aber bevor Sie Ihre Layouts und das Hinzufügen von Hörern auf Ansichten in Aktivitätsklasse Hinzufügen von Referenz müssen Sie überprüfen, welche aktuelle Ausrichtung andere weise sie in Nullpointer Absturz führen wird, wie Sie anhand der zu ergreifen, wird versuchen, die ist nicht aufgeblasen.

Was müssen Sie tun: -

• Entfernen Landschaft Aktivität von manifest
• Name ändern Landschaftsbelegung wie Porträt und verschieben Sie sie Ressourcenverzeichnis Layout-Land-Ordner in.
• Bevor Sie findviewbyId in der Aktivitätsklasse verwenden, müssen Sie prüfen, ob die aktuelle Ausrichtung Land oder Port ist.

Beispiel Arbeits-Code

Hauptaktivitätsklasse

public class HomeActivity erweitert FragmentActivity {

private UniversalWebViewFragment detailFragment; 

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

    ListView listView = (ListView) findViewById(R.id.selector); 

    final ArrayList<String> list = new ArrayList<String>(); 
    for (int i = 0; i < 10; i++) { 
     //Load random Google search URLS for List 
     list.add("https://www.google.com/search?q=" + i); 
    } 

    listView.setAdapter(new ArrayAdapter(this, android.R.layout.simple_list_item_1, list)); 

    if (!isPortrait(getApplicationContext())) { 
     detailFragment = (UniversalWebViewFragment) getSupportFragmentManager().findFragmentById(R.id.webView); 
    } 

    listView.setOnItemClickListener(new OnItemClickListener() { 

     @Override 
     public void onItemClick(AdapterView<?> arg0, View arg1, int arg2, long arg3) { 

      if (isPortrait(getApplicationContext())) { 

       Toast.makeText(getApplicationContext(), "Do Fragment Transition with URL" + list.get(arg2), 300).show(); 

      } else { 

       if (null != detailFragment) 
        detailFragment.loadURL(list.get(arg2)); 

      } 
     } 
    }); 

} 
//Check if device is in portrait mode 
public static boolean isPortrait(Context context) { 

    return context.getResources().getBoolean(R.bool.is_portrait); 
}

Answer 2

Try in Ihrer Aktivität außer Kraft zu setzen. wie 0,5 für beide

@Override 

public void onConfigurationChanged(Configuration newConfig) { 

    super.onConfigurationChanged(newConfig); 

} 

Answer 3

Keine Notwendigkeit, zwei xml in Ihrem Fall zu behandeln nur beide und gibt Gewicht in der Haupttätigkeit hinzuzufügen. und prüfen Sie, ob Sie im Hochformat-Modus ist, dann ein Fragment ausblenden und wenn der Benutzer ist Landschaft sichtbar zweiten Fragment.

und eine weitere Sache, die Sie nicht Max Gewicht Max. Gewicht des ersten Geschlechts gesetzt sind. und die meisten imp eine Zeile in menifest.xml

android:configChanges="orientation|screenSize" /> 

und fügen Sie, wenn Sie einen Code tun wollen, wenn Ausrichtung ändern, dann können Sie onConfigurationChanged() -Methode

@Override 
public void onConfigurationChanged(Configuration newConfig) { 
    super.onConfigurationChanged(newConfig); 
    // write here code 
    // here you can check orientation and set your code as per your requirement 
}
