java - 单击时禁用线程

Question

我正在开发计算特定应用程序运行时间的应用程序，为了节省内存，我想通过使用复选框来停止一些线程。我想要一个命令，当我按下复选框时，即使“如果条件”正确，线程也会停止”

检测应用的if条件:

if (MainActivity.tgbutton.isChecked())
{
    if (packageName.equals("com.facebook.katana"))
    {

        if (f==1)
        {

        }
        else
        {
            // Toast.makeText(getApplicationContext(),"fb on", Toast.LENGTH_SHORT).show();
            f=1;
            facebook = true;
            startTimef = SystemClock.uptimeMillis();
            customHandlerf.postDelayed(updateTimerThreadfacebook, 0);
        }
    }
    else
    {
        if(f==1)
        {
            //Toast.makeText(getApplicationContext(),"fb off", Toast.LENGTH_SHORT).show();

            facebook = false;
            timeSwapBufff += timeInMillisecondsf;

            customHandlerf.removeCallbacks(updateTimerThreadfacebook);
            f=2;
        }
    }
}

复选框:

blabla.setOnClickListener(new OnClickListener() {

    @Override
    public void onClick(View v) {

        if (((CheckBox) v).isChecked()) {

            // what to write here to disable thread???
        }

    }
});

线程本身:

private Runnable updateTimerThreadfacebook = new Runnable() {


    public void run() {


        if (facebook = true)
        {
            timeInMillisecondsf = SystemClock.uptimeMillis() - startTimef;

            updatedTimef = timeSwapBufff + timeInMillisecondsf;

            int secsf = (int) (updatedTimef / 1000);
            int minsf = secsf / 60;
            secsf = secsf % 60;

            MainActivity.facebook.setText("" + minsf + ":" + String.format("%02d", secsf));

            customHandlerf.postDelayed(this, 0);

        }
    }

};

您应该在运行方法中使用值

public class MyClass implements Runnable{
boolean signal=false;
public setisFinish(boolean sig)
{
    signal = sig;
}

@Override
public void run()
{
  if(!signal)
  //Do SomeThing
}

public void foo()
{
    System.out.println("foo");
}

}

并在您的点击监听器中

blabla.setOnClickListener(new OnClickListener() {

@Override
public void onClick(View v) {

    if (((CheckBox) v).isChecked()) {

       myThread.setisFinish(true);
    }

}

});

此代码恢复您的线程，您可以随时启动它，如果您想中断您的线程，请使用此代码

myThread.interrupt();
