Ich möchte die Hintergrundfarbe des Optionsmenüs (Überlauf) in Android 4.2 ändern. Ich habe alle Methoden ausprobiert, aber es wird immer noch die vom Thema festgelegte Standardfarbe angezeigt. Ich habe die folgenden Code- und XML-Konfigurationen verwendet.
MainActivity.java
public class MainActivity extends Activity {
@SuppressLint("NewApi")
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
getActionBar().setIcon(R.drawable.ic_launcher);
getActionBar().setTitle("Sample Menu");
getActionBar().setBackgroundDrawable(new
ColorDrawable(Color.parseColor("#33B5E5")));
int titleId = Resources.getSystem().getIdentifier("action_bar_title", "id", "android");
TextView titleText = (TextView)findViewById(titleId);
titleText.setTextColor(Color.parseColor("#ffffff"));
}
@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);
setMenuBackground();
return true;
}
protected void setMenuBackground(){
// Log.d(TAG, "Enterting setMenuBackGround");
getLayoutInflater().setFactory( new Factory() {
@Override
public View onCreateView(String name, Context context,
AttributeSet attrs) {
if ( name.equalsIgnoreCase( "com.android.internal.view.menu.IconMenuItemView" ) ) {
try { // Ask our inflater to create the view
LayoutInflater f = getLayoutInflater();
final View view = f.createView( name, null, attrs );
/* The background gets refreshed each time a new item is added the options menu.
* So each time Android applies the default background we need to set our own
* background. This is done using a thread giving the background change as runnable
* object */
new Handler().post( new Runnable() {
public void run () {
// sets the background color
view.setBackgroundResource( R.color.menubg);
// sets the text color
((TextView) view).setTextColor(Color.WHITE);
// sets the text size
((TextView) view).setTextSize(18);
}
} );
return view;
}
catch ( InflateException e ) {}
catch ( ClassNotFoundException e ) {}
}
return null;
}});
}
}
Menu.xml
<menu xmlns:android="http://schemas.android.com/apk/res/android" >
<item
android:id="@+id/action_settings"
android:icon="@drawable/menu"
android:showAsAction="always"
android:title="@string/action_settings">
<menu>
<item
android:id="@+id/item1"
android:showAsAction="always"
android:title="@string/item1" />
<item
android:id="@+id/item2"
android:showAsAction="always"
android:title="@string/item2" />
<item
android:id="@+id/item3"
android:showAsAction="always"
android:title="@string/item3" />
<item
android:id="@+id/item4"
android:showAsAction="always"
android:title="@string/item4" />
</menu>
</item>
</menu>
color.xml
<color name="menubg">#33B5E5</color>
Der obige setMenuBackground hat keine Wirkung:
Im obigen Bild möchte ich den Menühintergrund in der Aktionsleiste von schwarz auf blau ändern . Wie kann ich das erreichen und was habe ich falsch gemacht?
