public class Test3Activity extends Activity {

    public MediaPlayer player;


    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        Button b = (Button) findViewById(R.id.button1);
        b.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View v) {

                // TODO Auto-generated method stub

                MediaPlayer player = MediaPlayer.create(Test3Activity.this, R.raw.karkhe);
                player.setLooping(true);
                player.setVolume(100, 100);
                player.start();

            }
        });
        Button c = (Button) findViewById(R.id.Button01);
        c.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View v) {
                // TODO Auto-generated method stub
               
                player.stop();
            }
        });

    }
}

این کد رو جایگزین کن:

import android.app.Activity;
import android.content.Intent;
import android.media.MediaPlayer;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;


public class Test3Activity extends Activity {

    /** Called when the activity is first created. */

    public MediaPlayer player;


    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        
        player = MediaPlayer.create(Test3Activity.this, R.raw.karkhe);
        Button b = (Button) findViewById(R.id.button1);
        b.setOnClickListener(new OnClickListener() {
            @Override
            public void onClick(View v) {

                // TODO Auto-generated method stub
                player.setLooping(true);
                player.setVolume(100, 100);
                player.start();

            }
        });
        Button c = (Button) findViewById(R.id.Button01);
        c.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View v) {
                // TODO Auto-generated method stub
                player.pause();
            }
        });

    }
}

موفق باشی

ممنون اقا محسن ولی مشکل کجا بود من تغییری داخل کدها نمیبینم؟
