1. PlayerActivity.java
import androidx.appcompat.app.AppCompatActivity;
import android.media.MediaPlayer;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
public class PlayerActivity extends AppCompatActivity {
private MediaPlayer mMediaPlayer = null;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_player);
mMediaPlayer = MediaPlayer.create(this.getApplicationContext(),R.raw.dukou);
mMediaPlayer.setLooping(true);
Button btnPlay = findViewById(R.id.btn_play);
btnPlay.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
if(!mMediaPlayer.isPlaying()){
mMediaPlayer.start();
}
}
});
Button btnStop = findViewById(R.id.btn_stop);
btnStop.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
if(mMediaPlayer.isPlaying()){
mMediaPlayer.pause();
}
}
});
}
}
- 将测试用mp3文件直接导入raw目录下，通过R.raw.dukou引用
