将asset中的图片文件加载到ImageView中
// load image
try {
// get input stream
InputStream ims = getAssets().open("avatar.jpg");

Drawable d = Drawable.createFromStream(ims, null);
// set image to ImageView
mImage.setImageDrawable(d);
}
catch(IOException ex) {
return;
}
将asset中的图片文件绘制到自定义View中。
Bitmap bitmap;
try {
InputStream ims = this.getContext().getAssets().open("fl.jpg");
// 读入图片并将其强转为 BitmapDrawable类型
BitmapDrawable bd = (BitmapDrawable) Drawable.createFromStream(ims, null);
bitmap = bd.getBitmap();
ims.close();
}
catch(IOException ex) {
return;
}
//canvas.drawBitmap(bitmap, -200, -200, new Paint());
canvas.drawBitmap(bitmap, null, new Rect(-30,-40,30,40), new Paint());//null表示原图尺寸,第二个rect表示显示区域(位图会拉伸填充该区域)
