注意:此答案已引起广泛关注,我需要对其进行更新。自从原始答案发布以来,@ dzeikei的评论几乎和原始答案一样受到关注。因此,这里有两种可能的解决方案:
确保您的后台工作线程可以访问Context对象(可以是Application上下文或Service上下文)。然后只需在后台工作线程中执行此操作:
// Get a handler that can be used to post to the main thread
Handler mainHandler = new Handler(context.getMainLooper());
Runnable myRunnable = new Runnable() {
@Override
public void run() {....} // This is your code
};
mainHandler.post(myRunnable);
2.如果您的后台线程没有(或不需要)Context
对象
(由@dzeikei建议):
// Get a handler that can be used to post to the main thread
Handler mainHandler = new Handler(Looper.getMainLooper());
Runnable myRunnable = new Runnable() {
@Override
public void run() {....} // This is your code
};
mainHandler.post(myRunnable);
