这是一个prefect办法阻止handlerthread？ [英] Is this a prefect way to stop handlerthread?

问题描述

我总是创建两个处理器，一个是包木窗在主线程，一个是包木窗上一个单独的线程， 这是启动并在活动周期停止这些??一个最好的方法

  HandlerThread safeThread = NULL;
处理器safeHandler = NULL;
处理程序处理程序= NULL;


@覆盖
    公共无效的OnStart（）{

如果（safeThread == NULL）{
            safeThread =新HandlerThread（safeThread）;
            safeThread.start（）;
            safeHandler =新的处理程序（safeThread.getLooper（））;
        }否则，如果（safeThread.getState（）== Thread.State.NEW）{
            safeThread.start（）;
            safeHandler =新的处理程序（safeThread.getLooper（））;
        }否则，如果（safeThread.getState（）== Thread.State.WAITING）{
            safeHandler =新的处理程序（safeThread.getLooper（））;
        }否则，如果（safeThread.getState（）== Thread.State.TERMINATED）{
            safeThread = NULL;
            safeThread =新HandlerThread（safeThread）;
            safeThread.start（）;
            safeHandler =新的处理程序（safeThread.getLooper（））;
        }
}




保护无效的onStop（）{
        Log.d（×，的onStop被执行）;
        safeHandler = NULL;
        safeThread.quit（）;
        safeThread.interrupt（）;
        safeThread = NULL;
        super.onStop（）;
    }
 

解决方案

使用此作为其安全地停止线程。

 如果（safeThread！= NULL）{
 螺纹垂死= safeThread;
 safeThread = NULL;
 moribund.interrupt（）;
 }
 

i always create two handler , one is wraping on main thread , one is wraping on a single thread, is this a best method to start and stop these in a activity lifecycle ??

HandlerThread safeThread = null;
Handler safeHandler = null;
Handler handler = null;


@Override
    public void onStart() {

if (safeThread == null) {
            safeThread = new HandlerThread("safeThread");
            safeThread.start();
            safeHandler = new Handler(safeThread.getLooper());
        } else if (safeThread.getState() == Thread.State.NEW) {
            safeThread.start();
            safeHandler = new Handler(safeThread.getLooper());
        } else if (safeThread.getState() == Thread.State.WAITING) {
            safeHandler = new Handler(safeThread.getLooper());
        } else if (safeThread.getState() == Thread.State.TERMINATED) {
            safeThread = null;
            safeThread = new HandlerThread("safeThread");
            safeThread.start();
            safeHandler = new Handler(safeThread.getLooper());
        }
}




protected void onStop() {
        Log.d("x", "onStop is executed");
        safeHandler = null;
        safeThread.quit();
        safeThread.interrupt();
        safeThread = null;
        super.onStop();
    }

解决方案

Use this as its safe way to stop thread.

 if(safeThread!= null){
 Thread moribund = safeThread;
 safeThread = null;
 moribund.interrupt();
 }
