Java 在自定义线程类中执行可运行参数

我想在主线程中定义我的

runnable

，然后将其作为参数传递给另一个线程，如下所示-

final Runnable runnable = new Runnable() {
            @Override
            public void run() {

                Log.i("Running runnable","");
            }
        };

Handler handler = new Handler() {

    @Override
    public void handleMessage(Message msg) {
        super.handleMessage(msg);

        text.setText(msg.obj.toString());
    }
};

ThreadTest handlerThreadTest = new ThreadTest(runnable, handler);
                handlerThreadTest.start();

ThreadTest

类定义如下-

public class ThreadTest extends Thread {

private Handler handler;
private Runnable runnable;

public ThreadTest(Runnable runnable, Handler handler) {

    this.handler = handler;
    this.runnable = runnable;
}

@Override
public void run() {
    super.run();

    runnable.run();

    Message msg = handler.obtainMessage();
    msg.obj = "YUSSSSSS!";
    handler.sendMessage(msg);
} }

我可以将“yussss”消息发送给我的处理程序，但

runnable.run（）

似乎无法工作，因为我在logcat中看不到任何内容

---

我哪里弄错了

Logcat倾向于删除空消息，在日志中添加一些字符，您可能会在“Running runnable”标签下看到一些内容

Log.i("RunnableImpl", "Running runnable");
