标题[问题] 拦截home back 事件
时间Tue May 21 13:51:22 2013
@Override
public void onAttachedToWindow() {
this.getWindow().setType(WindowManager.LayoutParams.TYPE_KEYGUARD);
super.onAttachedToWindow();
}
@Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
if ((keyCode == KeyEvent.KEYCODE_BACK)) {
} else if ((keyCode == KeyEvent.KEYCODE_HOME)) {
}
return super.onKeyDown(keyCode, event);
}
错误:java.lang.IllegalArgumentException: Window type can not be changed after the
window is added.
想要拦截home back事件 却发生这个错误 这如何处理?
