动态添加一个Android印刷品吗？ [英] Dynamically add an Android canvas?

问题描述

我想我的画布动态添加到我的layoiut但有错误：
说明位置资源路径类型
在类型的ViewGroup的方法addView（查看）不适用于参数（Canvas）的Java问题

 画布油画=新的Canvas（）;
LL的LinearLayout =新的LinearLayout（本）;
ll.addView（画布）;
 

解决方案

有可能是一个根本性的错误你的问题。你实际上并没有增加画布，以一个视图。
您可以使用画布通过重写的onDraw方法在视图中（即SurfaceView）来绘制。

看看这个博客，怎么画布可以在Android中使用：

I want to dynamically add my canvas to my layoiut but this has the error: Description Location Resource Path Type The method addView(View) in the type ViewGroup is not applicable for the arguments (Canvas) Java Problem

Canvas canvas = new Canvas();
LinearLayout ll = new LinearLayout(this);
ll.addView(canvas);

解决方案

There might be something fundamentally wrong with your question. You don't actually "add a canvas" to a view. You use the canvas to draw in a view (ie. SurfaceView) by overriding the onDraw method.

Have a look at this blog, how the canvas can be used in Android: [http://www.tutorialforandroid.com/2010/11/drawing-with-canvas-in-android-renewed.html][1]
