绘制到一个ImageView的 [英] Draw onto an ImageView

问题描述

我研究了Androidreference几个小时了，但没有真正得到线索如何绘制一个ImageView的东西（文本，位图，路径....）。

I studied the Androidreference for hours now, but don't really get the clue how to draw something (Text, Bitmap, Path ....) on a ImageView.

我应该扩展查看和使用的onDraw（） - 方法？如果是的话，我怎么能吸取我的ImageView？

Should I extend View and use the onDraw()-Method? If yes, how can I draw on my ImageView?

或者是有其他的方式来实现我的目标？

Or is there any other way to achieve my goal?

推荐答案

如果你只是想画上你的ImageView另一个位图，它不应该是动态的，不是使用AbsoluteLayout及以上互相它们的位置。

If you just want to draw another bitmap on your ImageView and it shouldn't be dynamic, than use AbsoluteLayout and position them above each other.

如果它应该是更加动态，笔者推荐使用SurfaceView。该教程可以在这里找到：的http：// www.droidnova.com/playing-with-graphics-in-android-part-i,147.html

If it should be much more dynamic, I recommend to use a SurfaceView. A tutorial can be found here: http://www.droidnova.com/playing-with-graphics-in-android-part-i,147.html
