我想知道热键在按取消时关闭对话框吗？

推荐答案

您是否正在使用AlertDialog.Builder？实现自定义对话框的方法有很多，但是假设您的发送按钮是肯定按钮或中性按钮，而取消按钮是否定按钮，您总是可以这样做。

Are you using the AlertDialog.Builder? There are lots of way of implementing a custom Dialog but assuming your "Send" button is a positive or neutral button and your "Cancel" button is a negative button you can always do this.

@Override
public void onClick(DialogInterface dialog, int which) {
    if (which == Dialog.BUTTON_NEGATIVE)
        dialog.dismiss()
}

您也可以调用 dialog.cancel（）如果要调用 DialogInterface.OnCancelListener 。

You can also call dialog.cancel() if you want to invoke the DialogInterface.OnCancelListener.

如果不是这种情况，则需要提供其他信息。

If this is not the case you need to supply additional information.
