Canvas.scale（）在Android上。重绘全屏幕 [英] Canvas.scale() on Android. Redraw full screen

问题描述

所以我使用Android开发者的例子来实现捏放大在我的活动。

So I'm using the example on Android Developers to implement pinch to zoom on my Activity.

林缩放自定义视图具有滚动型（和其他的东西），它里面。

Im Scaling A Custom View which has a ScrollView(and other things) inside it.

当IM缩放，只有实际显示的屏幕被调整 - 但我想按比例缩小的东西来显示更多的内容，因为他们有更多的空间缩小时这样做。
我希望他们能够使用所有的全屏幕空间。

When im scaling, only the actual displayed Screen gets resized - but i want the scaled down things to show more of their content, because they have more space to do so when scaled down. I want them to use all the full screen space.

我的自定义视图的OnDraw方法只是看起来是这样的：

My Custom Views ondraw method just looks like this:

public void draw(Canvas canvas) {

    canvas.scale(mScaleFactor, mScaleFactor);
    super.draw(canvas);
}

这是什么样子，现在

如果有什么不清楚，只是发表评论。任何帮助AP preciated
编辑：我做了我的自定义视图另一种背景颜色，现在我看到，我的看法是依然充满屏幕只是没有孩子的

If anything is unclear, just leave a comment. Any Help is appreciated edit: i made my custom View another Background color and now i see that my View is still full screen just not the childs.

推荐答案

尝试迫使正在被使用缩放视图的大小的LayoutParams 。

Try forcing the size of the view that is being scaled with a LayoutParams.
