Android 简单的警报对话框 [英] Android simple alert dialog

问题描述

我需要向在我的 Android 应用程序上单击按钮的用户显示一条小短信，在 IOS 上我只需要创建一个易于使用的 AlertView，但是对于 Android，我正在努力，因为该解决方案似乎是 x10 倍更难.我看到我需要使用 DialogFragment 但我不明白如何使它工作，有人可以解释一下吗?另外，我的解决方案是否正确，或者有什么更简单的方法可以向用户显示简单的短信?

I need to show a little text message to the users that clicks a button on my Android app, on IOS I just had to create an AlertView that it's simple to use but with Android i'm struggling because the solution seems x10 times harder. I saw that I need to use a DialogFragment but I can't understand how to make it work, can someone explain? Also, is my solution right or there is something easier to show a simple text message to users?

推荐答案

您只需在 onClick 中执行此操作:

You would simply need to do this in your onClick:

AlertDialog alertDialog = new AlertDialog.Builder(MainActivity.this).create();
alertDialog.setTitle("Alert");
alertDialog.setMessage("Alert message to be shown");
alertDialog.setButton(AlertDialog.BUTTON_NEUTRAL, "OK",
    new DialogInterface.OnClickListener() {
        public void onClick(DialogInterface dialog, int which) {
            dialog.dismiss();
        }
    });
alertDialog.show();

我不知道您从哪里看出您需要 DialogFragment 来简单地显示警报.

I don't know from where you saw that you need DialogFragment for simply showing an alert.
