Select and crop with a maximum size in android
开发者_开发知识库What I want to do it's to show the crop box, but with a maximum size. Something like that:
Intent intent = new Intent();
intent.setType("image/*");
intent.putExtra("crop", "true");
intent.putExtra("max-width", 30);
intent.putExtra("max-height", 30);
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(Intent.createChooser(intent,
"Select Picture"), IMAGE_SELECTED);
Try this:
// Photo intent.
Intent intent = new Intent(Intent.ACTION_GET_CONTENT, null);
intent.setType("image/*");
// Intent parameters.
intent.putExtra("crop", "true");
intent.putExtra("aspectX", 30); // This sets the max width.
intent.putExtra("aspectY", 30); // This sets the max height.
intent.putExtra("outputX", 1);
intent.putExtra("outputY", 1);
intent.putExtra("scale", true);
intent.putExtra("return-data", true);
intent.putExtra(MediaStore.EXTRA_OUTPUT, newImageFile());
intent.putExtra("outputFormat", Bitmap.CompressFormat.JPEG.toString());
// Send intent.
activity.startActivityForResult(intent, BibleActivity.CROP_PHOTO_REQUEST_CODE);
To get the new image file:
/**
* Create new temporary file for cropped image.
* @return uri
*/
public Uri newImageFile() {
return Uri.fromFile(createFile(CROPPED_FILENAME));
}
/**
* Create file.
* @return file.
*/
private File createFile(String fileName) {
// Make sure we have SD Card.
if (isSDCARDMounted()) {
// File location.
File file = new File(activity.getExternalFilesDir(null), fileName);
try {
// Delete if exist.
if (file.exists())
file.delete();
// Create new file.
file.createNewFile();
} catch (IOException e) {
Toast.makeText(activity, R.string.error_cannot_create_temp_file, Toast.LENGTH_LONG).show();
}
return file;
} else {
Toast.makeText(activity, R.string.error_no_sd_card_present, Toast.LENGTH_LONG).show();
return null;
}
}
/**
* Check to make sure we have SD Card.
* @return
*/
private boolean isSDCARDMounted() {
if (Environment.getExternalStorageState().equals(Environment.MEDIA_MOUNTED))
return true;
else
return false;
}
try this, solve problem that image cropped with black frame.
Intent intent = new Intent();
intent.setType("image/*");
intent.putExtra("crop", "true");
intent.putExtra("scaleUpIfNeeded", true);//learn it from gallery2 source code
intent.putExtra("max-width", 30);
intent.putExtra("max-height", 30);
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(Intent.createChooser(intent,
"Select Picture"), IMAGE_SELECTED);
try to add the extra :
cropIntent.putExtra("return-data", false);
and set the outPut file
File f = new File(Environment.getExternalStorageDirectory(),
"/temporary_holder.jpg");
try {
f.createNewFile();
} catch (IOException ex) {
Log.e("io", ex.getMessage());
}
Uri uri = Uri.fromFile(f);
cropIntent.putExtra(MediaStore.EXTRA_OUTPUT, uri)
then retrieve the file ( not the data ) onActivityResult
String filePath = Environment.getExternalStorageDirectory()
+ "/temporary_holder.jpg";
cropBitmap = BitmapFactory.decodeFile(filePath);
