我正在使用InsertImage插入图像,但每次将图像存储在SD卡上时,其背景都会变黑。我怎样才能去掉那黑色的背景?
我的代码是:
> Bitmap Img = BitmapFactory.decodeResource(getResources(),
> R.drawable.ic_launcher); String path =
> Images.Media.insertImage(getContentResolver(), Img, "myImg", "Image");
最佳答案
请在将图像保存到SD卡之前使用此格式--->>>bitmap.compressformat.png如果使用bitmap.compressformat.jpeg,则问题将重复出现
public class SDCard {
public void setBitmap(Bitmap bitmap, String filename)
throws FileNotFoundException {
File folder = new File(Environment.getExternalStorageDirectory()
.getAbsolutePath() + "/JANU");
if (!folder.exists()) {
folder.mkdir();
}
File imagefile = new File(folder, filename);
FileOutputStream fout = new FileOutputStream(imagefile);
boolean bit = bitmap.compress(Bitmap.CompressFormat.PNG, 100, fout);
}
