BitMap、View以及Canvas是我们Ophone程序中常用到的类。本日以feisky的学习笔记呈现，通过实例讲解View&Canvas等等。

1. 从资源中获取位图

可以使用BitmapDrawable或者BitmapFactory来获取资源中的位图。



当然，首先需要获取资源：



Resources res=getResources()



使用BitmapDrawable获取位图



使用BitmapDrawable (InputStream is)构造一个BitmapDrawable；

使用BitmapDrawable类的getBitmap()获取得到位图；

// 读取InputStream并得到位图

InputStream is=res.openRawResource(R.drawable.pic180)

BitmapDrawable bmpDraw=new BitmapDrawable(is)

Bitmap bmp=bmpDraw.getBitmap()

或者采用下面的方式：

-BitMap, View and Canvas is we use class often Ophone program. This day to feisky study notes appear, through the examples explain View&Canvas and so on.

1. Get a bitmap from resources

Can use BitmapDrawable or BitmapFactory to obtain resources of the bitmap.



Of course, we first need to obtain resources:



Resources res = getResources ()



Use BitmapDrawable get a bitmap



Use BitmapDrawable (InputStream is constructing a BitmapDrawable

Use BitmapDrawable kind getBitmap () get get a bitmap

//read InputStream and get a bitmap

InputStream is = res. OpenRawResource (R.d rawable. Pic180)

BitmapDrawable bmpDraw = new BitmapDrawable (is)

Bitmap BMP = bmpDraw. GetBitmap ()

Or use the following ways:
