Activity

Read the comment and demo in next step, it should be self-explorary.

File : MainActivity.java

package com.jitesh.androidpromptdialog;

import android.app.Activity;

import android.app.AlertDialog;

import android.content.Context;

import android.content.DialogInterface;

import android.os.Bundle;

import android.view.LayoutInflater;

import android.view.View;

import android.view.View.OnClickListener;

import android.widget.Button;

import android.widget.EditText;

public class MainActivity extends Activity {

final Context context = this;

private Button button;

private EditText result;

public void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_main);

// components from main.xml

button = (Button) findViewById(R.id.buttonPrompt);

result = (EditText) findViewById(R.id.editTextResult);

// add button listener

button.setOnClickListener(new OnClickListener() {

@Override

public void onClick(View arg0) {

// get prompts.xml view

LayoutInflater li = LayoutInflater.from(context);

View promptsView = li.inflate(R.layout.prompt, null);

AlertDialog.Builder alertDialogBuilder = new AlertDialog.Builder(

context);

// set prompts.xml to alertdialog builder

alertDialogBuilder.setView(promptsView);

final EditText userInput = (EditText) promptsView

.findViewById(R.id.editTextDialogUserInput);

// set dialog message

alertDialogBuilder

.setCancelable(false)

.setPositiveButton("OK",

 new DialogInterface.OnClickListener() {

   public void onClick(DialogInterface dialog,int id) {

// get user input and set it to result

// edit text

result.setText(userInput.getText());

   }

 })

.setNegativeButton("Cancel",

 new DialogInterface.OnClickListener() {

   public void onClick(DialogInterface dialog,int id) {

dialog.cancel();

   }

 });

// create alert dialog

AlertDialog alertDialog = alertDialogBuilder.create();

// show it

alertDialog.show();

}

});

}

}
