android - How to start a background thread in Android

Question

This might be a stupid question, but I'll ask it anyway.

How do you start a background thread off the UI thread without using AsyncTask or Handler or Service or any other Android-provided structure? I want to create a new Thread to do some Bitmap processing, and given the bugs that were reported against AsyncTask, I'd like to avoid those classes. I know they are the Google-recommended way to background a task, but let's pretend I can't use them...just for fun. :)

If it's not possible, I'd like to know why. If it is, how do I do this?

Answer 1

您可以new Thread从主 UI 线程启动一个处理Bitmap没有问题。它会做你需要做的事情，并且不会以任何方式阻塞主 UI 线程。但是，您不能从新创建的线程直接操作您的UI线程。

Answer 2

你可以试试Thread

Thread initBkgdThread = new Thread(new Runnable(){
     public void run(){


         //Things that you wanted to do in background here.

      }
});
initBkgdThread.start();

Answer 3

new Thread(new Runnable()
{   
    @Override
    public void run()
    {
       // Your code here                        
    }
}).start();
