Question

我一直在努力让一个线程在我的应用程序的后台启动并运行。我的问题是，如何创建一个线程并从按钮启动它？我很抱歉创造了这个问题，但我花了至少5个小时没有任何进展。

your_button_id.setOnClickListener(new OnClickListener() {                       
            @Override
            public void onClick(View v) {
                // TODO Auto-generated method stub                      
                startThread();                          
            }
        });

create method 

public void startThread()
{
    Thread backgroundthread =new Thread( new Runnable() 
        {

            public void run()
            {

//Write your code that should be run on thread.Dont render UI here.
//render UI after thread in response handler like this...
    responceHandler.sendEmptyMessage(0);


}});backgroundthread.start();
}

private Handler responceHandler = new Handler() {
        @Override
        public void handleMessage(Message msg) {

if(msg.what==0)
{
//Handle your UI here 
}
}};
