Question

我有一个帖子。该线程从服务器加载数据并将其设置在列表视图中。

点击重启按钮后，我想取消或停止线程然后重启此线程。

我已使用while(true)并使用interrupt主题并使用stop()，但无效！

Answer 1

如果在/

之前启动了线程，则无法重新启动线程抛出IllegalThreadStateException

要停止或启动线程，请使用以下代码

import android.util.Log;

public class ThreadingEx implements Runnable {

    private  Thread backgroundThread;
    private static final String TAG = ThreadingEx.class.getName();


    public void start() {
       if( backgroundThread == null ) {
          backgroundThread = new Thread( this );
          backgroundThread.start();
       }
    }

    public void stop() {
       if( backgroundThread != null ) {
          backgroundThread.interrupt();
       }
    }

    public void run() {
        try {
           Log.i(TAG,"Starting.");
           while( !backgroundThread.interrupted() ) {
             //To Do
           }
           Log.i(TAG,"Stopping.");
        } catch( Exception ex ) {

           Log.i(TAG,"Exception."+ex);
        } finally {
           backgroundThread = null;
        }
    }
}

Answer 2

public class MyActivity extends Activity {

private Thread mThread;  

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


    mThread =  new Thread(){
    @Override
    public void run(){
        // Perform thread commands...
for (int i=0; i < 5000; i++)
{
  // do something...
}

// Call the stopThread() method.
        stopThread(this);
      }
    };

// Start the thread.
    mThread.start(); 
}

private synchronized void stopThread(Thread theThread)
{
if (theThread != null)
{
    theThread = null;
}
}
}

您可以使用字段告诉您的线程停止，重新启动或取消。

class TheThread extends Thread {
    private boolean running = true;

    public void run() {
        // do this...
        // do that...
        // .......

        if (!running) return;

        //Continue your job
    }
}
