Question

I’m creating Android application contains 2 buttons, on click on each button play a mp3 file.
The problem is when I play button1 it plays sound1, when I click button2 it plays sound2.

I check on each button the other player if it’s working and I stop it and play the clicked one

But If I click on same button twice it’s keep first audio playing in the background and play another one again

I tried to check isPlaying() and to stop it, but it doesn’t work!

I want If I click on button1 it play sound1 and if clicked on it again it stop it and play it again from beginning.

My code:

package com.hamoosh.playaudio;
import android.app.Activity;
import android.media.MediaPlayer;
import android.media.MediaPlayer.OnCompletionListener;
import android.os.Bundle;
import android.os.Handler;
import android.view.View;
import android.widget.Button;
import android.widget.TextView;

public class PlayaudioActivity extends Activity {
/** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        Button b= (Button) findViewById(R.id.button1);
        Button b2= (Button) findViewById(R.id.button2);
        final TextView t= (TextView) findViewById(R.id.textView1);

        final MediaPlayer mp = MediaPlayer.create(PlayaudioActivity.this, R.raw.far);
        final MediaPlayer mp1 = MediaPlayer.create(PlayaudioActivity.this, R.raw.beet);

        b.setOnClickListener(new View.OnClickListener() {

            @Override
            public void onClick(View v) {
                if (mp1.isPlaying()) {

                    mp1.stop();
                }

                mp.start();
            }

        });

        b2.setOnClickListener(new View.OnClickListener() {

            @Override
            public void onClick(View v) {
                if (mp.isPlaying()) {

                    mp.stop();
                }
                mp1.start();
            }
        });
    }
}

Hope if there any better code that can use multiple buttons as an array or something to not check each button and player every time.

You should use only one mediaplayer object

    public class PlayaudioActivity extends Activity {

        private MediaPlayer mp;

        /** Called when the activity is first created. */
        @Override
        public void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.main);
            Button b = (Button) findViewById(R.id.button1);
            Button b2 = (Button) findViewById(R.id.button2);
            final TextView t = (TextView) findViewById(R.id.textView1);

            b.setOnClickListener(new View.OnClickListener() {

                @Override
                public void onClick(View v) {
                    stopPlaying();
                    mp = MediaPlayer.create(PlayaudioActivity.this, R.raw.far);
                    mp.start();
                }

            });

            b2.setOnClickListener(new View.OnClickListener() {

                @Override
                public void onClick(View v) {
                    stopPlaying();
                    mp = MediaPlayer.create(PlayaudioActivity.this, R.raw.beet);
                    mp.start();
                }
            });
        }

        private void stopPlaying() {
            if (mp != null) {
                mp.stop();
                mp.release();
                mp = null;
           }
        }
    }
