开发过程中相信大家都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); } 复制代码 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。
