這是TQC的310題，

程式碼為自行撰寫，

僅供參考。

 

主要練習MediaPlayer，

並在背景播放。

 

//是否正在播放
if (mMediaPlayer.isPlaying())
{
mMediaPlayer.pause()
}

 

 

 

 

package COM.TQC.GDD03;

import android.app.Activity;
import android.media.MediaPlayer;
import android.os.Bundle;
import android.widget.TextView;

public class GDD03 extends Activity
{
   private MediaPlayer mMediaPlayer01;
   private TextView  TextView1;
	
  /** Called when the activity is first created. */
  @Override
  public void onCreate(Bundle savedInstanceState)
  {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
    
    findview();
    setmedia();
   
    
  }
  public void findview()
  {
	  TextView1=(TextView)findViewById(R.id.textView1);
	  TextView1.setText("ready");
  }
  public void setmedia()
  {
	  mMediaPlayer01=MediaPlayer.create(this,R.raw.light); 	    
	  mMediaPlayer01.start();	    
	  if(mMediaPlayer01.isPlaying())
	  	{
	    	TextView1.setText("isPlaying");
	    }
  }
  
  protected void onPause()
  {	 
	  mMediaPlayer01.stop();
	  if(!mMediaPlayer01.isPlaying())
	    {
	    	TextView1.setText("stop");
	    }
	  super.onPause();   
  }
  
 
  protected void onResume()
  {	  
	  mMediaPlayer01.start();
	  if(mMediaPlayer01.isPlaying())
	    {
	    	TextView1.setText("isPlaying");
	    }	    
	    super.onResume();   
  }

}
