但它很老，也没有一个令人满意的答案。

The setVideoURI method of VideoView in Android seems to be blocking the UI thread. As soon as I call this method, the UI get's laggy, even on fast devices. Is there a way to improve performance here? The only other thread with that topic I could find here:

but it's quite old and doesn't have a satisfying answer.

推荐答案

我所做的就是地方setVideoUri（）方法与一个活套即一个处理程序。

What i did was place the setVideoUri() method into a handler with a looper i.e.

new Handler(Looper.myLooper()).post(new Runnable(){
    @Override
    public void run(){
        videoview.setVideoUri("uri");
    }
});

这运行在主UI线程之外code，但仍保留在钩子因此code可以在不引发异常被执行

this runs the code outside the main UI thread, but keeps it in a looper so the code can be executed without throwing an exception
