Android通过Intent调用系统拍照程序出现图片太小的问题解决办法

Intent it = newIntent("android.media.action.IMAGE_CAPTURE");
startActivityForResult(it, Activity.DEFAULT_KEYS_DIALER);

protectedvoidonActivityResult(intrequestCode, intresultCode, Intent data) {
   super.onActivityResult(requestCode, resultCode, data);
   try{
     Bundle extras = data.getExtras();
     Bitmap b = (Bitmap) extras.get("data");
     take = b;
     ImageView img = (ImageView)findViewById(R.id.image);
     img.setImageBitmap(take);
   }catch(Exception e){
   }
 
}

Intent it = newIntent("android.media.action.IMAGE_CAPTURE");
it.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(newFile(F.SD_CARD_TEMP_PHOTO_PATH)));
startActivityForResult(it, Activity.DEFAULT_KEYS_DIALER);

protectedvoidonActivityResult(intrequestCode, intresultCode, Intent data) {
   super.onActivityResult(requestCode, resultCode, data);
   try{
     ImageView img = (ImageView)findViewById(R.id.image);
     take = U.ResizeBitmap(U.getBitmapForFile(F.SD_CARD_TEMP_PHOTO_PATH), 640);
     img.setImageBitmap(take);
     imgflag = true;
   }catch(Exception e){
 
   }
 
}

public static Bitmap ResizeBitmap(Bitmap bitmap, intnewWidth) {
 
   intwidth = bitmap.getWidth();
   intheight = bitmap.getHeight();
   floattemp = ((float) height) / ((float) width);
   intnewHeight = (int) ((newWidth) * temp);
   floatscaleWidth = ((float) newWidth) / width;
   floatscaleHeight = ((float) newHeight) / height;
   Matrix matrix = newMatrix();
   // resize the bit map
   matrix.postScale(scaleWidth, scaleHeight);
   // matrix.postRotate(45);
   Bitmap resizedBitmap = Bitmap.createBitmap(bitmap, 0, 0, width, height, matrix, true);
   bitmap.recycle();
   return resizedBitmap;
 
}
