本文介绍了在Android环境中创建和使用线程的方法，包括直接继承Thread类和实现Runnable接口两种方式，并展示了如何启动多个线程及设置线程名称。

最简单的一个线程应用的例子：

public class TestActivity extends Activity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.mainActivity);

        new Thread(){
            @Override
            public void run(){
                System.out.println("Thread is starting...");
            }
        }.start();
    }
}

使用Runnable的例子：

Runnable runnable = new Runnable() {
    @Override
    public void run(){
        System.out.println("Runnable is starting...");
    }
};

new Thread(runnable).start();
}
}

常见的Multi-Thread的用法:

        MyTestThread myTestThread1 = new MyTestThread();
        MyTestThread myTestThread2= new MyTestThread();
        MyTestThread myTestThread3 = new MyTestThread();

        myTestThread1.start();
        myTestThread2.start();
        myTestThread3.start();

}
}

class MyTestThread extends Thread {
    @Override
    public void run() {
         System.out.println(Thread.currentThread().getName() + " is running...");
    }
}

运行结果：

I/System.out(672): Thread-10 is running...

I/System.out(672): Thread-11 is running...

I/System.out(672): Thread-12 is running...

以上代码还可以使用实例化Multi-Thread的用法:

MyTestThread myTestThread = new MyTestThread();

new Thread(myTestThread, "My Thread 1").start();
new Thread(myTestThread, "My Thread 2").start();
new Thread(myTestThread, "My Thread 3").start();

运行结果：

I/System.out(672): My Thread 1 is running...

I/System.out(672): My Thread 2 is running...

I/System.out(672): My Thread 3 is running...
