屏幕锁定时，WebView媒体内容停止(调用活动的onStop) [英] WebView media content stops when the screen is locked ( activity's onStop is called)

问题描述

我有一个应用程序，可以在MainActivity的WebView中播放视频.我遇到的问题是，每当锁定屏幕时，视频就会暂停(调用onStop活动，即WebView中的视频暂停时).

I have an App that plays a video inside a WebView on my MainActivity. The problem I am having is that the video is pausing whenever I lock the screen (Activity's onStop is called, that is when the video in the WebView is paused).

但是这种行为仅发生在 Apis> = Lollipop(5.0)上.

But this behavior only occurs on Apis >= Lollipop(5.0).

我到处都在寻找解决方案，但找不到任何东西.我只希望即使用户在LockScreen上也能继续播放视频.

I searched everywhere for a solution, but I could not find anything. I just want the video to keep playing even when the user is on LockScreen.

推荐答案

如果您的WebView由于onStop而暂停，则可以覆盖WebView中的onWindowVisibilityChanged:

If your WebView is pausing because of the onStop, you can override onWindowVisibilityChanged from WebView:

public class MyWebView extends WebView {

    public MyWebView(Context context) {
        super(context);
    }

    public MyWebView(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    public MyWebView(Context context, AttributeSet attrs, int defStyleAttr) {
        super(context, attrs, defStyleAttr);
    }

    @Override
    protected void onWindowVisibilityChanged(int visibility) {
        if (visibility != View.GONE) super.onWindowVisibilityChanged(visibility);
    }
}
