Android simple alert dialog
提问by LS_
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?
我需要向点击我的 Android 应用程序上的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，但对于 Android，我正在努力，因为该解决方案似乎要困难 10 倍。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，或者有什么更容易向用户显示简单短信的方法？

You would simply need to do this in your onClick:
你只需要在你的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();
I don't know from where you saw that you need DialogFragment for simply showing an alert.
我不知道你从哪里看到你需要 DialogFragment 来简单地显示警报。
Hope this helps.

You can easily make your own 'AlertView' and use it everywhere.
您可以轻松制作自己的“AlertView”并随处使用。
alertView("You really want this?");
Implement it once:
实现一次：
private void alertView( String message ) {
AlertDialog.Builder dialog = new AlertDialog.Builder(context);
dialog.setTitle( "Hello" )
.setIcon(R.drawable.ic_launcher)
.setMessage(message)
// .setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
// public void onClick(DialogInterface dialoginterface, int i) {
// dialoginterface.cancel();
// }})
.setPositiveButton("Ok", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialoginterface, int i) {
}
}).show();
}
