本文实例讲述了Android编程实现Home键的屏蔽，捕获与修改方法。分享给大家供大家参考，具体如下：

个人补充：此方法需要加权限，而且修改后拦截了home键，所以建议慎用~

开发过程中相信大家都曾有碰到因为不能捕获Home键而烦恼，现在终于有办法了，在Level5以上(包含)中，Activity类中有如下方法:

public void onAttachedToWindow ()

Since: API Level 5

Called when the main window associated with the activity has been attached to the window manager. See View.onAttachedToWindow() for more information.

See Also

* onAttachedToWindow()

private boolean catchHomeKey = false; @Override public void onAttachedToWindow() { // TODO Auto-generated method stub if(catchHomeKey) { this.getWindow().setType(WindowManager.LayoutParams.TYPE_KEYGUARD); } super.onAttachedToWindow(); } @Override public boolean onKeyDown(int keyCode, KeyEvent event) { // TODO Auto-generated method stub if(keyCode == KeyEvent.KEYCODE_HOME) { Log.e(TAG, "Home key down"); } return super.onKeyDown(keyCode, event); }

重写Activity中的onAttachedToWindow方法，设置Type，就能捕获到Home键。

当不需要捕获时，删除setType这一行就OK。

希望本文所述对大家Android程序设计有所帮助。
