1.继承Thread

public class java_thread extends Thread{
	public static void main(String args[])
	{
		(new java_thread()).run();
		System.out.println("main thread run ");
	}
	public synchronized void run()
	{
		System.out.println("sub thread run ");
	}

}

2.实现Runnable接口

public class java_thread implements Runnable{
	public static void main(String args[])
	{
		(new Thread(new java_thread())).start();
		System.out.println("main thread run ");
	}
	public void run()
	{
		System.out.println("sub thread run ");
	}

}

3.直接在函数体使用

void java_thread()
{

   Thread t = new Thread(new Runnable(){
      public void run(){
      mSoundPoolMap.put(index, mSoundPool.load(filePath, index));
      getThis().LoadMediaComplete();
      }});
		t.start();
}
