android - 当方向改变时，以某种方式调用按钮的 onclicklistener

Question

出现问题的视图里面有一个按钮和一个tabhost。该按钮的 onclick 侦听器会更改当前选项卡中的一些文本。问题是当我更改方向（端口到着陆或着陆到端口）时，按钮的 onclicklistener 会以某种方式被调用/浏览，并且当前选项卡中的文本会发生变化。为什么会发生这种情况，解决方案是什么？

myActivity extends Activity{
    onCreate(bundle){
        ..
        ..
        add(button1);
        button1.onClickListner(new OnClickListener(){
             ..
             someAlertDialog.show();             //line xxx

        });
    }

}

它实际上没有显示任何警报对话框（它不应该这样做）但说错误日志中有泄漏@line xxx。整个日志即将推出。

编辑：我现在无法获取错误日志，但是方向更改后仍然发生一些奇怪的事情。

What happens by default on an orientation change is that the current activity instance is destroyed and then recreated and passed the previous instance's state. If a dialog is on screen when this happens it will leak the window that's displaying it.

Since you are not using Activity#showDialog which will manage dialogs when onDestroy is called you have to do that manually. So you'll have to override Activity#onDestroy and call Dialog#dismiss if it is showing.
