 
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; 
} 

關(guān)鍵代碼就是重寫Layout類的工廠方法onCreateView，這里對比繪制的View來替換系統(tǒng)中的

復(fù)制代碼代碼如下:

 
protected void setMenuBackground(){ 
Log.d(TAG, "開始設(shè)置菜單的的背景"); 
getLayoutInflater().setFactory( new Factory() { 
@Override public View onCreateView ( String name, Context context, AttributeSet attrs ) { 
if ( name.equalsIgnoreCase( "com.android.internal.view.menu.IconMenuItemView" ) ) { 
//上面這句Android123提醒大家不能有改動，目前來看對于原生android目前這個packageName還沒有變化 
try { 
LayoutInflater f = getLayoutInflater(); 
final View view = f.createView( name, null, attrs ); //嘗試創(chuàng)建我們自己布局 
new Handler().post( new Runnable() { 
public void run () { 
view.setBackgroundResource( R.drawable.cwj"_bg); //設(shè)置背景為我們自定義的圖片，替換cwj_bg文件即可 } } ); 
return view; 
} catch ( 
InflateException e ) {} 
catch ( 
ClassNotFoundException e ) {} 
} 
return null; 
} }); }}
