您可以从图像路径创建图像缩略图:
public Bitmap getbitpam(String path){
Bitmap imgthumBitmap=null;
try
{
final int THUMBNAIL_SIZE = 64;
FileInputStream fis = new FileInputStream(path);
imgthumBitmap = BitmapFactory.decodeStream(fis);
imgthumBitmap = Bitmap.createScaledBitmap(imgthumBitmap,
THUMBNAIL_SIZE, THUMBNAIL_SIZE, false);
ByteArrayOutputStream bytearroutstream = new ByteArrayOutputStream();
imgthumBitmap.compress(Bitmap.CompressFormat.JPEG, 100,bytearroutstream);
}
catch(Exception ex) {
}
return imgthumBitmap;
}
在文件路径上调用此方法单击以在ImageView中显示图像缩略图
