Main_activity.xml

package com.programmingwap.playsound;



import android.media.MediaPlayer;

import android.support.v7.app.AppCompatActivity;

import android.os.Bundle;

import android.view.View;

import android.widget.Button;

import android.widget.TextView;



public class MainActivity extends AppCompatActivity {



    Button playBtn;

    TextView textView;



    @Override

    protected void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);

        setContentView(R.layout.activity_main);



        //intialize i.e Link with R



        playBtn = (Button) findViewById(R.id.playBtn);

        textView = (TextView)findViewById(R.id.txtView);



        playBtn.setOnClickListener(new View.OnClickListener() {

            @Override

            public void onClick(View v) {

                // Sound Function call here when user press the button

                playSound();



            }

        });



    }



    //function definition

    private void playSound(){



        //crystall_ball is the name of the sound clip



        MediaPlayer player = MediaPlayer.create(this ,R.raw.crystal_ball);

        player.start();



        player.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {

            @Override

            public void onCompletion(MediaPlayer mp) {

                //Run those code when sound is off



                textView.setText("Sound Succesfully played");



            }

        });



    }



}

Explanation:

·         You modify the crystal_ball with your audio file.

         Audio file pasted in res->raw->your_audio_file.mp3

         MediaPlayer player = MediaPlayer.create(this ,R.raw.crystal_ball);

·          setOnCompletionListener() is a method which absorb the completiton of the sound.

         When sound played then all the code within this block run.

        player.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {

            @Override

            public void onCompletion(MediaPlayer mp) {

                //Run those code when sound is off



                textView.setText("Sound Succesfully played");



            }

        });
