Android: Play mp3 file from raw resource on click of a TextView

Question

Hi guys I want to play a certain mp3 file when a text is clicked. For example, I clicked the word "Nicholas", the app have to play nicholas.mp3...

Sorry for my messy code, I'm new to android dev:

package com.example.playword;

import java.io.IOException;

import android.app.Activity;
import android.media.MediaPlayer;
import android.os.Bundle;
//import android.os.Handler;
import android.view.View;
//import android.view.View.OnClickListener;
//import android.widget.Button;
import android.widget.TextView;

public class PlayWord extends Activity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        //final Handler mHandler = new Handler();

        final TextView nicholas = (TextView) findViewById(R.id.nicholas);
        final TextView was = (TextView) findViewById(R.id.was);

        nicholas.setText("Nicholas ");
        was.setText("was ");        

        /*
        Button btn = (Button) (findViewById(R.id.nicholasBtn));

        btn.setOnClickListener(new OnClickListener(){
            @Override
            public void onClick(View v) {
                nicholas.setText("Nicholas (Clicked!) ");
            }

          });
        */

        View.OnClickListener handler = new View.OnClickListener(){
            public void onClick(View v) {
                switch (v.getId()) {
                    case R.id.nicholas: // doStuff

                        MediaPlayer mPlayer = MediaPlayer.create(null, R.raw.aaanicholas);

                        try {
                            mPlayer.prepare();
                        } catch (IllegalStateException e) {
                            // TODO Auto-generated catch block
                            e.printStackTrace();
                        } catch (IOException e) {
                            // TODO Auto-generated catch block
                            e.printStackTrace();
                        }

                        mPlayer.start();

                        nicholas.setText("Nicholas (Clicked!) ");
                        break;

                    case R.id.was: // doStuff

                        MediaPlayer mPlayer1 = MediaPlayer.create(null, R.raw.aaawas);

                        try {
                            mPlayer1.prepare();
                        } catch (IllegalStateException e) {
                            // TODO Auto-generated catch block
                            e.printStackTrace();
                        } catch (IOException e) {
                            // TODO Auto-generated catch block
                            e.printStackTrace();
                        }

                        mPlayer1.start();

                        was.setText("was (Clicked!) ");
                        break;
                }
            }
        };

        findViewById(R.id.nicholas).setOnClickListener(handler);
        findViewById(R.id.was).setOnClickListener(handler);

    }
}

When I run this, I'm getting a force close error.. Do you have a much better idea on this? Many thanks in advance!

Answer 1

You need to pass in a context instance into MediaPlayer.create method:

MediaPlayer mPlayer = MediaPlayer.create(PlayWorld.this, R.raw.aaanicholas);

Also, after the create() call, prepare is already executed, so you don't need to execute it explicitly, just invoke start() right after create().

Answer 2

When you create the mPlayer object you should pass it the Context, which is in your case PlayWord.this.

Answer 3

MediaPlayer mPlayer = MediaPlayer.create(FakeCallScreen.this, R.raw.mysoundfile);
    mPlayer.start();
