我正在尝试制作一个应用程序，播放特定的声音按钮单击，我得到了100个按钮创建静态不是在一个数组或任何东西，我分配给每个按钮正确的声音问题是，打了许多按钮后，它给我的错误，我的问题是错误（-19,0）媒体播放器
- 任何方式我可能从这个烂摊子切换到通用代码
- 反正我可以停止收到此错误和声音继续在每个按钮上工作，无论播放的是多少声音？
下面是我的代码：
package com.example.buttonsdemo;
import android.media.MediaPlayer;
import android.os.Bundle;
import android.app.Activity;
import android.util.Log;
import android.view.Menu;
import android.view.View;
import android.widget.Button;
import android.widget.Toast;
public class MainActivity extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Button messageButton_0 = (Button) findViewById(R.id.akali);
final MediaPlayer mpButtonClick_0= MediaPlayer.create(this,R.raw.akali) ;
messageButton_0.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View arg0) {
mpButtonClick_0.start();
if(!mpButtonClick_0.isPlaying()){
mpButtonClick_0.stop();
mpButtonClick_0.release();
}
}
});
它继续这样下去的100多个按钮或因此任何帮助PLZ

您可能需要添加logcat来查看您正在收到的错误种类 – DigCamara 2013-03-04 16:18:28
刚刚添加logcat – 2013-03-04 16:22:43
如果我没有弄错，错误-19应该是'NO_INIT'。这可能发生，例如如果MediaPlayer无法创建基础AudioTrack，如果setDataSource失败或者在初始化MediaPlayer之前调用某些方法。 – Michael 2013-03-04 16:25:58
