如何在Android中唤醒一个线程睡眠

Question

我有一个活动多数民众赞成等待用户按图像。如果用户在3秒钟内不按任何东西，我想关闭活动（完成（））。 这就是我的代码：

private final int delay = 3000; 
public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.after_hangup); 
    getWindow().addFlags(WindowManager.LayoutParams.FLAG_SHOW_WHEN_LOCKED); 
    final ImageView pressToLaunchbrowser = (ImageView) findViewById(R.id.after_hang_up_image); 

    pressToLaunchbrowser.setOnClickListener(new OnClickListener() { 

     @Override 
     public void onClick(View v) { 
      //getWindow().addFlags(WindowManager.LayoutParams.FLAG_DISMISS_KEYGUARD); // if we want to open the device. 
      Intent intent = new Intent(Intent.ACTION_VIEW); 
      intent.setData(Uri.parse(url)); 
      startActivity(intent); 
      Thread.interrupted(); 
     } 
    }); 
    new Thread() { 
     public void run() { 
      try { 
        Thread.sleep(delay); 
        finish(); 
      } 
      catch (InterruptedException e) { 
       e.printStackTrace(); 
      } 
     } 
    }.start(); 
}} 

我的问题是如何唤醒线程，如果新闻媒体是？我试过Thread.interrupted();，但它不工作。该线程仍然等待3秒，如果我按或不。谢谢！

import android.app.Activity; 
import android.content.Intent; 
import android.net.Uri; 
import android.os.Bundle; 
import android.os.Handler; 
import android.view.View; 
import android.view.View.OnClickListener; 
import android.view.WindowManager; 
import android.widget.ImageView; 

public class NewActivity extends Activity { 

    private final int delay = 3000; 

    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.after_hangup); 
     getWindow().addFlags(WindowManager.LayoutParams.FLAG_SHOW_WHEN_LOCKED); 
     final ImageView pressToLaunchbrowser = (ImageView) findViewById(R.id.after_hang_up_image); 

     final Handler handler = new Handler(); 
     handler.postDelayed(finishRunnable, delay); 
     pressToLaunchbrowser.setOnClickListener(new OnClickListener() { 

      @Override 
      public void onClick(View v) { 
       // getWindow().addFlags(WindowManager.LayoutParams.FLAG_DISMISS_KEYGUARD); 
       // // if we want to open the device. 
       Intent intent = new Intent(Intent.ACTION_VIEW); 
       intent.setData(Uri.parse(url)); 
       startActivity(intent); 
       handler.removeCallbacks(finishRunnable); 
      } 
     }); 

    } 

    private Runnable finishRunnable = new Runnable() { 

     @Override 
     public void run() { 
      finish(); 

     } 
    }; 
}

线程，不建议在Android..use处理程序使用管理，而不是new Thread()时间依赖性operations..for例如，..，尝试

Handler handler = new Handler(); 
handler.postDelayed('runnable-that-will-finish-activity', 3000); 

和onclicklistener：

handler.remove('runnable-that-will-finish-activity') ;
