我有一个很奇怪的问题，
我试图禁用切换按钮仅几秒钟，以使应用程序中的人们无法对它进行spamclick。
我的toggleButton具有此侦听器：
videoToggleListener = new OnCheckedChangeListener() {
@Override
public void onCheckedChanged(CompoundButton buttonView,
boolean isChecked) {
switchVideoSource();
switchBetweenSources.setEnabled(false);
freezeToggle.schedule(new TimerTask(){
@Override
public void run() {
switchBetweenSources.setEnabled(false);
switchBetweenSources.setEnabled(true);
}
}, 1000);
}
};
我的应用程序不会在setEnabled（false）上强制关闭，但会在setEnabled（true）上强制关闭。
任何想法 ？

编辑：
我已经这样改变了我的听众：
videoToggleListener = new OnCheckedChangeListener() {
@Override
public void onCheckedChanged(CompoundButton buttonView,
boolean isChecked) {
switchVideoSource();
switchBetweenSources.setEnabled(false);
freezeToggle.schedule(new TimerTask(){
@Override
public void run() {
runOnUiThread(new Runnable(){
@Override
public void run() {
switchBetweenSources.setEnabled(true);
}
});
}
}, 2000);
}
};
谢谢大家，您真棒=）！
最佳答案
显然，问题是您尝试从非UI线程更改View。如果您说您没有在TimerTask的第一行得到此异常，而只是在第二行，则可能是因为您的ToggleButton已被禁用，并且不会更改View。
要从UI线程以外的其他View更改Thread的状态，应使用runOnUiThread()。
