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...");
}
};
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(runnable).start();
}
}
常见的Multi-Thread的用法:
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);
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...
线程休眠：sleep (待续)
线程优先级：priority (待续)
线程让步(调度)：yield (待续)
后台线程：daemon (待续)
使用执行器：Executer (待续)
定义任务：Runnable (待续)
