最常見：

ImageView.setImageResource(R.drawable.icon);

看下面這段話

Sets a drawable as the content of this ImageView.

This does Bitmap reading and decoding on the UI thread, which can cause a latency hiccup. If that's a concern, consider usingsetImageDrawable(Drawable)orsetImageBitmap(Bitmap)andBitmapFactoryinstead.

這個ImageView設置一個動態引用的圖片內容。（我在這里因為資源引用卡住了，記得有不同方法getString，getDrawable，getInteger）

如果這是一個問題,考慮usingsetImageDrawable(可移動)或setImageBitmap(位圖)和BitmapFactory代替。

此函數使用UI線程，可以用下面3種替代：

ImageView iv;

String fileName = "/data/data/com.test/aa.png;

Bitmap bm = BitmapFactory.decodeFile(fileName);

iv.setImageBitmap(bm);

ImageView iv = new ImageView(context);

iv.setImageResource(iv[position]);

iv.setScaleType(ImageView.ScaleType.FIT_XY);

iv.setLayoutParams(new Gallery.LayoutParams(136,88));

mImageView = (ImageView)this.findViewById(R.id.myImageView1);

mImageView.setImageDrawable(getResources().getDrawable(R.drawable.right)

/*

*?從Assets中讀取圖片

*/

Bitmapbitmapimg =?getImageFromAssetsFile("Cat_Blink/cat_blink0000.png");

private Bitmap?getImageFromAssetsFile(String?fileName)

{

Bitmap?image?=null;

AssetManager?am?=?getResources().getAssets();

try

{

InputStream?is?=?am.open(fileName);

image?=?BitmapFactory.decodeStream(is);

is.close();

}

catch(IOException?e)

{

e.printStackTrace();

}

returnimage;

}
