testButton.setOnClickListener(new Button.OnClickListener(){

public void onClick(View v)
{
imageView.setImageBitmap(Bitmap);
imageView.buildDrawingCache();
Bitmap bm =imageView.getDrawingCache();
Intent imageIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);

File output = new File(imagesFolder, fileName);
Uri uriSavedImage = Uri.fromFile(output);
imageIntent.putExtra(MediaStore.EXTRA_OUTPUT, uriSavedImage);
OutputStream fos = null;
try {
fos = getContentResolver().openOutputStream(uriSavedImage);
bm.compress(CompressFormat.JPEG, 100, fos);
fos.flush();
fos.close();

首先,我检索从SD卡的图像(640×480)分辨率的图像视图。话又说回来,我从图像视图到SD卡上保存的图像。但保存的图像分辨率为(188x113)。任何人都可以建议我怎么可以用相同的分辨率保存。任何建议将AP preciable。
First i retrieved an image from sd card to image view of resolution (640 x 480). Then again i saved the image from image view to sd card. But the image saved is of resolution is (188x113). Can anyone suggest how i can save with the same resolution. Any suggestions will be appreciable.
推荐答案
试试这个code:
BitmapDrawable btmpDr = (BitmapDrawable) ivPic.getDrawable();
Bitmap bmp = btmpDr.getBitmap();
/*File sdCardDirectory = Environment.getExternalStorageDirectory();*/
try
{
File sdCardDirectory = new File(Environment.getExternalStorageDirectory() + File.separator + "MeeguImages");
sdCardDirectory.mkdirs();
imageNameForSDCard = "image_" + String.valueOf(random.nextInt(1000)) + System.currentTimeMillis() + ".jpg";
File image = new File(sdCardDirectory, imageNameForSDCard);
FileOutputStream outStream;
outStream = new FileOutputStream(image);
bmp.compress(Bitmap.CompressFormat.JPEG, 100, outStream);
/* 100 to keep full quality of the image */
outStream.flush();
outStream.close();
//Refreshing SD card
sendBroadcast(new Intent(Intent.ACTION_MEDIA_MOUNTED, Uri.parse("file://"+ Environment.getExternalStorageDirectory())));
}
catch (Exception e)
{
e.printStackTrace();
Toast.makeText(ViewImage.this, "Image could not be saved : Please ensure you have SD card installed " +
"properly", Toast.LENGTH_LONG).show();
}
