推荐答案

如果您发布code，我可以给你一个更好的答案。然而，定期更新视图的常用方法是使用处理程序。

If you post your code, I can give you a better answer. However, a common way to update views periodically is by using Handlers.

private final Handler mHandler = new Handler(); //intialize in main thread

public void test() {
    mHandler.postDelayed(new Runnable() {

        @Override
        public void run() {
            mTextView.setText("hello");

        }
    }, 1000);
}
