[android] Android AlertDialog Single Button

I'd like to have an AlertDialog builder that only has one button that says OK or Done or something, instead of the default yes and no. Can that be done with the standard AlertDialog, or would I have to use something else?

For code reuse, You can make it in a method like this

public static Dialog getDialog(Context context,String title, String message, DialogType typeButtons ) {

        AlertDialog.Builder builder = new AlertDialog.Builder(context);
        builder.setTitle(title)
        .setMessage(message)
               .setCancelable(false);

        if (typeButtons == DialogType.SINGLE_BUTTON) {
            builder.setPositiveButton("OK", new DialogInterface.OnClickListener() {
                   public void onClick(DialogInterface dialog, int id) {
                        //do things
                   }
               });
        }

        AlertDialog alert = builder.create();

        return alert;
    }

    public enum DialogType {
        SINGLE_BUTTON

    }

//Other code reuse issues like using interfaces for providing feedback will also be excellent.

This is the closer I could get to the one liner this should be if the Android API was any smart:

new AlertDialog.Builder(this)
    .setMessage(msg)
    .setPositiveButton("OK", null)
    .show();

Its very simple

new AlertDialog.Builder(this).setView(input).setPositiveButton("ENTER",            
                        new DialogInterface.OnClickListener()                      
                        {   public void onClick(DialogInterface di,int id)     
                            {
                                output.setText(input.getText().toString());
                            }
                        }
                     )
        .create().show();

Kotlin?

  val dialogBuilder = AlertDialog.Builder(this.context)
  dialogBuilder.setTitle("Alert")
               .setMessage(message)
               .setPositiveButton("OK", null)
               .create()
               .show()

You could use this:

AlertDialog.Builder builder1 = new AlertDialog.Builder(this);
builder1.setTitle("Title");
builder1.setMessage("my message");
builder1.setCancelable(true);
builder1.setNeutralButton(android.R.string.ok,
        new DialogInterface.OnClickListener() {
    public void onClick(DialogInterface dialog, int id) {
        dialog.cancel();
    }
});

AlertDialog alert11 = builder1.create();
alert11.show();

Another approach

Builder alert = new AlertDialog.Builder(ActivityName.this);
alert.setTitle("Doctor");
alert.setMessage("message");
alert.setPositiveButton("OK",null);
alert.show(); 

Bonus

AlertDialog.Builder builder = new AlertDialog.Builder(YourActivityName.this);
builder.setMessage("Message dialog with three buttons");

       builder.setPositiveButton("YES", new DialogInterface.OnClickListener() {
           public void onClick(DialogInterface dialog, int id) {
                //do things
           }
       });

      builder.setNegativeButton("NO", new DialogInterface.OnClickListener() {
           public void onClick(DialogInterface dialog, int id) {
                //do things
           }
       });

       builder.setNeutralButton("CANCEL", new DialogInterface.OnClickListener()     {
           public void onClick(DialogInterface dialog, int id) {
                //do things
           }
       });
AlertDialog alert = builder.create();
alert.show();

Now it is up to you to use one,two or three buttons..

In Mono for Android you can do this:

var ad = new AlertDialog.Builder(this);
ad.SetTitle("Title");
ad.SetMessage("Message");
ad.SetPositiveButton("OK", delegate { ad.Dispose(); });
ad.Show();
