试试这个：

import java.awt.event.ActionEvent;

import java.awt.event.ActionListener;

import javax.swing.JFrame;

import javax.swing.JRadioButton;

public class test {

public static volatile boolean activated = false;

public test() {

JFrame q = new JFrame();

q.setLayout(null);

q.setSize(400, 400);

q.setLocationRelativeTo(null);

q.setTitle("Tv something?");

JRadioButton button = new JRadioButton("on/off");

button.setSize(100, 40);

button.setLocation(q.getWidth()/2 - button.getWidth()/2, q.getHeight()/2 - button.getHeight()/2);

button.addActionListener(new ActionListener() {

@Override

public void actionPerformed(ActionEvent e) {

if (button.isSelected()) {

activated = true;

} else {

activated = false;

}

}

});

q.add(button);

q.setVisible(true);

}

}

现在采取的(挥发性)布尔并把它里面你可以运行像Silvans索兰奇建议是这样的：

final Runnable updater = new Runnable() {

public void run() {

if(activated){

updateTv();

push(mEMA);

}

}

};

编辑：

对于Android你可以做这样的事情：

Button btn= new Button(this);

btn.settext("Submit");

btn.setOnClickListener(new View.OnClickListener()

{

public void onClick(View view)

{

activated = !activated;

}

});
