如何在android中提示用户使用类似Toast的消息？

Question

I want the user to confirm an action by showing them a dialogue with a message and "yes" or "no" buttons. How can I make that appear, and perform actions based on the button they pick?

Thanks, AlertDialog looks like what I'm looking for. But, there's an error where it says "AlertDialog.Builder(this);" that tells me, "The constructor AlertDialog.Builder(new View.OnClickListener(){}) is undefined" –

Answer 1

As shown here :

private static final int DIALOG = 1;

to show the dialog call

showDialog(DIALOG);

override onCreateDialog, check with a switch for the dialog ID and insert

AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setMessage("Are you sure about this?")
   .setCancelable(false)
   .setPositiveButton("Yes", new DialogInterface.OnClickListener() {
       public void onClick(DialogInterface dialog, int id) {
            // whatever if YES
       }
   })
   .setNegativeButton("No", new DialogInterface.OnClickListener() {
       public void onClick(DialogInterface dialog, int id) {
            // whetever if NO
       }
   });
AlertDialog alert = builder.create();

What you're looking for is an AlertDialog . Using the example here , you can easily create a Yes/No dialog that will look something along the lines of:

Answer 3

You create a new AlertDialog.Builder , pass it some parameters, finally invoke its create() method and assign the return value to an AlertDialog object to hold a reference to it.

AlertDialog.Builder adb = new AlertDialog.Builder(this);
        adb.setTitle("Question");
        adb.setMessage(Html.fromHtml("Visit Stackoverflow?"));
        adb.setPositiveButton("Yes", new DialogInterface.OnClickListener() {
            public void onClick(DialogInterface dialog, int which) {
                // Action for YES
                startActivity(
                         new Intent(
                                Intent.ACTION_VIEW,
                                Uri.parse("http://www.stackoverflow.com")));
                return;
            }
        });

        adb.setNegativeButton("No", new DialogInterface.OnClickListener() {
            public void onClick(DialogInterface dialog, int which) {
                // Action for NO
                return;
            }
        });

AlertDialog myDialog = adb.create();

it's simple as below

new AlertDialog.Builder(this)
            .setTitle("Info")
            .setMessage("hello")
            .setPositiveButton("Yes", new DialogInterface.OnClickListener() {
                public void onClick(DialogInterface arg0, int arg1) {
                    // Some stuff to do when ok got clicked                 
                }
            })
            .setNegativeButton("No", new DialogInterface.OnClickListener() {
                public void onClick(DialogInterface arg0, int arg1) {
                    // Some stuff to do when ok got clicked
                }
            })
            .show();
