如何将声音设置为GridView的铃声？

Question

我试图从我的活动中设置声音文件作为铃声？ 我尝试了很多代码没有发生，并没有出现错误！

这是我的代码：

package com.De7kat.Grid;

import java.io.File; 

public class De7katGrid extends Activity { 
private MediaPlayer mp; 

这是我的声音文件中定义为整数数组

public Integer[] mSongsIds = { R.raw.l_1, R.raw.l_2, R.raw.l_3, R.raw.l_4, 
     R.raw.l_5, R.raw.l_6, R.raw.l_7, R.raw.l_8, R.raw.tom, R.raw.love, 
     R.raw.b_1, R.raw.b_2, R.raw.b_3, R.raw.b_4, }; 


public Object getItem(int position) { 
    int j = position; 
    return mSongsIds[position]; 

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

    GridView gridView = (GridView) findViewById(R.id.grid_view); 
    registerForContextMenu(gridView); 
    // Instance of ImageAdapter Class 
    gridView.setAdapter(new ImageAdapter(this)); 

阵列当点击gridview的项目将发挥的声音文件一个依赖于项目

gridView.setOnItemClickListener(new OnItemClickListener() { 
     @Override 
     public void onItemClick(AdapterView<?> parent, View v, 
       int position, long id) { 
      // Toast.makeText(De7katGrid.this, "" + position, Toast.LENGTH_SHORT).show(); 
      stopPlaying(); 
      mp = MediaPlayer.create(De7katGrid.this, mSongsIds[position]); 
      mp.start(); 

     } 
    }); 
} 

@Override 
public void onPause() { 
    super.onPause(); 
    stopPlaying(); 

} 

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

    } 
} 

当用户的ID和位置点击长按菜单将出现选择“设置为铃声”的声音位置，他们选择

public void onCreateContextMenu(ContextMenu menu, View v,ContextMenuInfo menuInfo) { 
    super.onCreateContextMenu(menu, v, menuInfo); 
     menu.setHeaderTitle("Context Menu"); 
     menu.add(0, v.getId(), 0, "Set As RingTone"); 
     menu.add(0, v.getId(), 0, "Set As Notification"); 


    } 


    public boolean onContextItemSelected(MenuItem item) { 
     if(item.getTitle()=="Set As RingTone"){ 
      function1(item.getItemId()); 
      } 
     else if(item.getTitle()=="Set As Notification"){function2(item.getItemId());} 
     else {return false;} 
    return true; 
    } 

这里必须发送mSongsIds [position]到saveas函数，但它会导致错误原因位置在这个级别没有定义？所以我通过R.raw.b1我的一个声音文件来测试功能

public void function1(int id){ 
     saveas(R.raw.b_1); 
     Toast.makeText(this, "function 1 called", Toast.LENGTH_SHORT).show(); 


    } 


    public void function2(int id){ 
     Toast.makeText(this, "function 2 called", Toast.LENGTH_SHORT).show(); 
    } 

这里是我的功能来设置铃声？不工作，因为我跟踪它，它达到它的结束..

public boolean saveas(int ressound){ 
     byte[] buffer=null; 
     InputStream fIn = getBaseContext().getResources().openRawResource(ressound); 
     int size=0; 

     try { 
      size = fIn.available(); 
      buffer = new byte[size]; 
      fIn.read(buffer); 
      fIn.close(); 
     } catch (IOException e) { 
      // TODO Auto-generated catch block 
      return false; 
     } 

     String path="/sdcard/media/audio/ringtone/"; 
     String filename="examplefile"+".ogg"; 

     boolean exists = (new File(path)).exists(); 
     if (!exists){new File(path).mkdirs();} 

     FileOutputStream save; 
     try { 
      save = new FileOutputStream(path+filename); 
      save.write(buffer); 
      save.flush(); 
      save.close(); 
     } catch (FileNotFoundException e) { 
      // TODO Auto-generated catch block 
      return false; 
     } catch (IOException e) { 
      // TODO Auto-generated catch block 
      return false; 
     }  
     sendBroadcast(new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE, Uri.parse("file://"+path+filename))); 
     File k = new File(path, "mysong.mp3"); // path is a file to /sdcard/media/ringtone 

     ContentValues values = new ContentValues(); 
     values.put(MediaStore.MediaColumns.DATA, k.getAbsolutePath()); 
     values.put(MediaStore.MediaColumns.TITLE, "My Song title"); 
     values.put(MediaStore.MediaColumns.SIZE, 215454); 
     values.put(MediaStore.MediaColumns.MIME_TYPE, "audio/mp3"); 
     values.put(MediaStore.Audio.Media.ARTIST, "Madonna"); 
     values.put(MediaStore.Audio.Media.DURATION, 230); 
     values.put(MediaStore.Audio.Media.IS_RINGTONE, true); 
     values.put(MediaStore.Audio.Media.IS_NOTIFICATION, false); 
     values.put(MediaStore.Audio.Media.IS_ALARM, false); 
     values.put(MediaStore.Audio.Media.IS_MUSIC, false); 

     //Insert it into the database 
     Uri uri = MediaStore.Audio.Media.getContentUriForPath(k.getAbsolutePath()); 
     Uri newUri = this.getContentResolver().insert(uri, values); 

     RingtoneManager.setActualDefaultRingtoneUri(
      this, 
      RingtoneManager.TYPE_RINGTONE, 
      newUri 
     ); 
      //Insert it into the database,, << I didn't get this one ?? what database 
      this.getContentResolver().insert(MediaStore.Audio.Media.getContentUriForPath(k.getAbsolutePath()), values); 

     return true; 
     } 

}

试试这个！

public void onItemClick(final AdapterView<?> arg0, final View view, 
     final int position, final long id) { 

    Item item = data.get(position); 
    changeMusic(item.getSound()); 

} 

private void changeMusic(int ring) { 
    mediaPlayerCount++; 

    if (mediaPlayerCount > 10) { 

     mediaPlayer.reset(); 
    } 

    if (mediaPlayer.isPlaying()) { 
     mediaPlayer.stop(); 
     mediaPlayer = MediaPlayer.create(SoundActivity.this, ring); 
     mediaPlayer.start(); 

    } else { 
     mediaPlayer = MediaPlayer.create(SoundActivity.this, ring); 
     mediaPlayer.start(); 
    } 

}
