Answer 1

OnKeyLongPress不能用键菜单工作。 （这不叫）
这里是解决方案，我发现：

private static long timer = 0; 
private static final long LONG_PRESS_TIME = 200; 

@Override 
public boolean onKeyDown(int keyCode, KeyEvent event) { 
    if (DEBUG && ConfigApp.DEBUG) { 
     Log.d(TAG, "onKeyDown"); 
    } 

    if (keyCode == KeyEvent.KEYCODE_MENU) { 
     if (timer == 0) { 
      timer = System.currentTimeMillis(); 
      return false; 
     } 

     // Longpress 
     if (System.currentTimeMillis() - timer > LONG_PRESS_TIME) { 
      return true; 
     } else { 
      timer = System.currentTimeMillis(); 
      return false; 
     } 

    } else { 
     return super.onKeyDown(keyCode, event); 
    } 
} 

@Override 
public boolean onKeyUp(int keyCode, KeyEvent event) { 
    if (DEBUG && ConfigApp.DEBUG) { 
     Log.d(TAG, "onKeyUp"); 
    } 

    if (keyCode == KeyEvent.KEYCODE_MENU) { 
     timer = 0; 
    } 
    return super.onKeyUp(keyCode, event); 
}

我找货源，以解决您的问题，在应用的launcher2。
https://android.googlesource.com/platform/packages/apps/Launcher2/+/master/src/com/android/launcher2/Launcher.java

@Override 
public boolean onKeyDown(int keyCode, KeyEvent event) { 
    boolean handled = super.onKeyDown(keyCode, event); 


    // Eat the long press event so the keyboard doesn't come up. 
    if (keyCode == KeyEvent.KEYCODE_MENU && event.isLongPress()) { 
     return true; 
    } 

    return handled; 
}
