android 自定义Android菜单背景的代码

public class MenuEx extends Activity {
private static final String TAG = "android123";
@Override public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
}
@Override public boolean onCreateOptionsMenu(Menu menu) {
super.onCreateOptionsMenu(menu);
MenuInflater inflater = new MenuInflater(getApplicationContext());
inflater.inflate(R.menu.options_menu, menu);
setMenuBackground();
return true;
}

protected void setMenuBackground(){
Log.d(TAG, "开始设置菜单的的背景");
getLayoutInflater().setFactory( new Factory() {
@Override public View onCreateView ( String name, Context context, AttributeSet attrs ) {
if ( name.equalsIgnoreCase( "com.android.internal.view.menu.IconMenuItemView" ) ) {
//上面这句Android123提醒大家不能有改动，目前来看对于原生android目前这个packageName还没有变化
try {
LayoutInflater f = getLayoutInflater();
final View view = f.createView( name, null, attrs ); //尝试创建我们自己布局
new Handler().post( new Runnable() {
public void run () {
view.setBackgroundResource( R.drawable.cwj"_bg); //设置背景为我们自定义的图片，替换cwj_bg文件即可 } } );
return view;
} catch (
InflateException e ) {}
catch (
ClassNotFoundException e ) {}
}
return null;
} }); }}
