webview 中的视频应在 android 中的 onShowCustomView() 方法上全屏显示

【中文标题】webview 中的视频应在 android 中的 onShowCustomView() 方法上全屏显示

【英文标题】：video in webview should display full screen on onShowCustomView() method in android

【问题描述】：

我想全屏显示视频（水平全屏）横向.. 当 onShowCustomView() 方法被调用时，

在我的情况下发生的事情是视频以相同的方向显示，其中 onShowCustomView() 方法被调用...也就是说屏幕是纵向的，而 onShowCustomView() 被称为视频垂直全屏显示，我想要它应该水平全屏显示

【参考方案1】：

我刚刚遇到了你的问题，我用另一种方式来处理它。

其实onShowCustomView返回的view是一个VideoView或者它的父亲。它是垂直的，因为您的设备方向是纵向的。所以我们可以在全屏视图的容器上做点什么。只需将“横向”布局作为您的容器。

这是我的简单代码：

public class LandscapeFrameLayout extends FrameLayout 

    public LandscapeFrameLayout(Context context, AttributeSet attrs) 
        super(context, attrs);
    

    @Override
    protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) 
        super.onMeasure(heightMeasureSpec, widthMeasureSpec);
        setMeasuredDimension(MeasureSpec.getSize(widthMeasureSpec), MeasureSpec.getSize(heightMeasureSpec));
    

    @Override
    protected void onLayout(boolean changed, int left, int top, int right, int bottom) 
        //Attention: The arithmetic below is based on padding == 0.
        final int count = getChildCount();
        for (int i = 0; i < count; i++) 
            View child = getChildAt(i);
            if (child != null) 
                child.setRotation(90);
                int width = right - left;
                int height = bottom - top;
                child.setTranslationX((width - height) / 2);
                child.setTranslationY((height - width) / 2);
            
        
        super.onLayout(changed, 0, 0, bottom, right);
    

上面的代码所做的是将它的子元素旋转 90 度并调整那里的位置。
