Las pestañas de la barra de acción no llenan la pantalla en android

Me utilizan la barra de acción de la ayuda en una aplicación y la prueba en 2 dispositivos Nexus S y Nexus 7 y encontré resultados diferentes con respecto al ancho de la barra de la lengüeta, Nexus S barra de la lengüeta ancho mientras que nexo 7 barra de la lengüeta deja un poco de espacio en lado izquierdo. He utilizado el tema por defecto proporcionado por la barra de acción de apoyo, la aplicación de temas personalizados no efecto barra de acción porque el estilo padre debe ser Theme.AppCompat.Light

Actividad en Manifest

<activity android:name=".MainActivity" android:screenOrientation="portrait" android:theme="@style/Theme.AppCompat.Light" > <android.support.v4.view.ViewPager android:id="@+id/pager" android:layout_width="match_parent" android:layout_height="match_parent" />

Clase:

 public class MainActivity extends ActionBarActivity implements ActionBar.TabListener { ActionBar bar; ViewPager pager; TabsAdapter adapter; @Override protected void onCreate(Bundle savedInstanceState) { // TODO Auto-generated method stub super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); pager = (ViewPager) findViewById(R.id.pager); bar = getSupportActionBar(); adapter = new TabsAdapter(getSupportFragmentManager()); bar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS); bar.setHomeButtonEnabled(false); pager.setAdapter(adapter); pager.setOnPageChangeListener(new ViewPager.SimpleOnPageChangeListener() { @Override public void onPageSelected(int position) { // When swiping between different app sections, select the // corresponding tab. // We can also use ActionBar.Tab#select() to do this if we have // a reference to the // Tab. bar.setSelectedNavigationItem(position); } }); Tab hometab = bar.newTab(); hometab.setText("Home"); hometab.setTabListener(this); bar.addTab(hometab); Tab cameratab = bar.newTab(); cameratab.setText("Camera"); cameratab.setTabListener(this); bar.addTab(cameratab); Tab exploretab = bar.newTab(); exploretab.setText("Explore"); exploretab.setTabListener(this); bar.addTab(exploretab); bar.show(); } @Override public boolean onCreateOptionsMenu(Menu menu) { // Inflate the menu items for use in the action bar MenuInflater inflater = getMenuInflater(); inflater.inflate(R.menu.main, menu); return super.onCreateOptionsMenu(menu); } @Override public void onTabReselected(Tab arg0, FragmentTransaction arg1) { // TODO Auto-generated method stub } @Override public void onTabSelected(Tab arg0, FragmentTransaction arg1) { // TODO Auto-generated method stub pager.setCurrentItem(arg0.getPosition()); } @Override public void onTabUnselected(Tab arg0, FragmentTransaction arg1) { // TODO Auto-generated method stub }

}

Utilice imágenes de alta resolución para tablets.Puede que dentro de la carpeta drawable-xxhdpi. Si esta solución no funciona. Entonces

Método alternativo:

Pasos

1: Crear 3 diseños separados – uno para la pestaña Inicio, uno para la pestaña de la cámara y otro para la pestaña de exploración.

2: Usando Layout Inflater, puede agregar este diseño por separado a estas pestañas.

Código de muestra:
