问题
I'm trying to change the standard light grey to a light green. Seems that there is not a simple way to do this (through Android Themes, for example) but I have found a workaround as explained at this page: http://tinyurl.com/342dgn3.
The author seems disappeared, can someone help me integrating this code? I don't understand where I need to implement the LayoutInflater
factory class.
回答1:
When ur are inflating the menu call this setMenuBackground() method
@Override
public boolean onCreateOptionsMenu(Menu menu)
{
MenuInflater inflater=getMenuInflater();
inflater.inflate(R.menu.menu,menu);
setMenuBackground();
return true;
}
and write this in the setMenuBackground() method
protected void setMenuBackground(){
// Log.d(TAG, "Enterting setMenuBackGround");
getLayoutInflater().setFactory( new Factory() {
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.androidcolor);
// sets the text color
((TextView) view).setTextColor(Color.BLACK);
// sets the text size
((TextView) view).setTextSize(18);
}
} );
return view;
}
catch ( InflateException e ) {}
catch ( ClassNotFoundException e ) {}
}
return null;
}});
}

This is clearly a problem that a lot of programmers have and to which Google has yet to provide a satisfactory, supported solution.
The setMenuBackground() hack which Abhay Kumar and Nik Reiman posted is a good start but it either crashes or does not work on Android 2.3.
Please see my answer (Louis Semprini) in this stackoverflow question for a better commented and more refined hack that works on 2.1, 2.2, and 2.3 (and that should do no harm on 3.X, though we can never guarantee this):

Use the setMenuBackground in onCreate.
