我想全屏显示视频（水平全屏）景观.. 当调用onShowCustomView（）方法时，

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...即屏幕是纵向和onShowCustomView（）被称为视频垂直全屏显示，我想要它应该水平全屏显示

我刚遇到你的问题，我以另一种方式处理它。

实际上，onShowCustomView返回的视图是VideoView或其父亲。它是垂直的，因为您的设备方向是纵向。所以我们可以在全屏视图的容器上做一些事情。只需将“横向”布局作为容器即可。

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);
    }
}

上面的代码是将孩子旋转90度并调整位置。

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