How would I override a Dialog's onBackPressed to close the dialog as well as calling finish() on the Activity it is located in?

推荐答案

您可以使用<一个href="http://developer.android.com/reference/android/content/DialogInterface.OnCancelListener.html"><$c$c>setOnCancelListener:

dialog.setOnCancelListener(new DialogInterface.OnCancelListener()
{
    @Override
    public void onCancel(DialogInterface dialog)
    {
         MyActivity.this.finish();
    }
});

您需要完成只有你的活动。对话框会自动关闭。

You need to finish only your activity. Dialog will be dismissed automatically.
