方法一: view.post(Runnable action)
textView.post(
new Runnable() {
@Override
public void run() {
textView.setText("更新textView");
//还可以更新其他的控件
imageView.setBackgroundResource(R.drawable.update);
}
});
方法二: activity.runOnUiThread(Runnable action)
((MainActivity) context).runOnUiThread(new Runnable() {
@Override
public void run() {
//此时已在主线程中,可以更新UI了
}
});
方法三: Handler机制
Handler mainHandler = new Handler(Looper.getMainLooper());
mainHandler.post(new Runnable() {
@Override
public void run() {
//已在主线程中,可以更新UI
}
});
