audio - android - how to make a button click play a sound file every time it been pressed?

Question

I have open a new project -

Now what I would like to do is this - By pressing on the button I want an mp3 file being played - and also that each time the button is pressed than the sound file will start playing from the start of it once again - so let's say that the mp3 is 10 sec long, and I pressed the button and it's playing and after 4 sec I pressed the button again than the sound will be played again.

Now what I would like to know is- 1- Where should I put the mp3 file?

2-what code do I have to add in order that when the button is pressed than the mp3 file will be played (let's call the mp3 file click_sound.mp3)?

3- What I need to add to the code in order that the sound will be played again each time I will pressed the button?

This is the code of the MainActivity.java -

package com.example.test1;

import android.os.Bundle;
import android.app.Activity;
import android.view.Menu;

public class MainActivity extends Activity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.main, menu);
        return true;
    }

}

and this is the activity_main.xml

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    tools:context=".MainActivity" >

    <Button
        android:id="@+id/button1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="@string/play" />

</RelativeLayout>

Answer 1

1. You should put mp3 file in /assets folder.

2. put this code inside onCreate() method after setContentView()

   final MediaPlayer mp = new MediaPlayer();
   Button b = (Button) findViewById(R.id.button1); 
   
   b.setOnClickListener(new OnClickListener() {
   
       @Override
       public void onClick(View v) {
   
           if(mp.isPlaying())
           {  
               mp.stop();
           } 
   
           try {
               mp.reset();
               AssetFileDescriptor afd;
               afd = getAssets().openFd("AudioFile.mp3");
               mp.setDataSource(afd.getFileDescriptor(),afd.getStartOffset(),afd.getLength());
               mp.prepare();
               mp.start();
           } catch (IllegalStateException e) {
               e.printStackTrace();
           } catch (IOException e) {
               e.printStackTrace();
           }
   
   
   
       }
   });
   

   3.sound will be played again each time you press button. You don't have to write any extra code for that.

Note that AudioFile.mp3 is the name of the mp3 file in /assets folder

Hope this answer is helpful:)
