我如何确定我的 android runnable 在工作线程上启动？
How can I be sure that my android runnable started on a worker thread?
我正在尝试学习如何使用线程在 Android/Java 上执行后台任务。我做了一个简单的测试应用程序，它纯粹做了一个新的线程（新的 Runnable（））并在可运行的内部休眠。当这是 运行 时，我仍然可以点击 UI 上的按钮（我可以看到视觉反馈）。
很高兴这是有效的，我将相同的代码移到了我的主应用程序代码库中，但它似乎仍然是 运行 在 UI 线程上，因为 GUI 锁并在睡眠循环完成后弹出 ANR。
谁能帮我弄清楚为什么我的 backgroundThread 不是 运行 在后台或工作线程上？
LoginService.java
package com.example.services;
import android.app.Activity;
import android.os.Handler;
import android.os.Looper;
import android.os.Message;
import android.util.Log;
public class LoginService implements ILoginService {
private Handler handler;
public LoginService() {
handler = new Handler(Looper.getMainLooper()){
@Override
public void handleMessage(Message msg) {
// Handle a message from the background task
Log.d("LoginService","Received a Message");
}
};
}
/*
Check if the username exists in the list
*/
@Override
public boolean isUsernameValid(String username) {
Log.d("LoginService","Starting Runnable");
Thread backgroundThread = new Thread(new LoginRunnable(this));
backgroundThread.run();
Log.d("LoginService", "Started Runnable");
return true;
}
/*
Check if the password is correct for the downloaded user
*/
@Override
public boolean doesPasswordMatch(String password) {
return false;
}
@Override
public void handleStatus(int i) {
switch (i) {
case 1:
Message newMessage = handler.obtainMessage();
newMessage.sendToTarget();
break;
default:
break;
}
}
}
LoginRunnable.java
package com.example.services;
import android.util.Log;
public class LoginRunnable implements Runnable {
public ILoginService loginService;
public LoginRunnable(ILoginService loginService)
{
this.loginService = loginService;
}
@Override
public void run() {
// Do the login tasks here
try {
for(int i = 0;i<=50;i++) {
Thread.sleep(200);
Log.d("LoginRunnable","200ms has passed");
loginService.handleStatus(1);
}
} catch (InterruptedException e) {
e.printStackTrace();
}
// Return some completion message to the LoginService.
}
}
