Good, I have the following code and I would like to know if it can be modified to be executed from a fragment, the issue is that there are parts that I do not know how to modify and that turn red in the android studio
This is the code:
private void captureImageInitialization() {
/**
* a selector dialog to display two image source options, from camera
* ‘Take from camera’ and from existing files ‘Select from gallery’
*/
final String[] items = new String[] { "Tomar desde la cámara",
"Seleccionar de la galeria" };
ArrayAdapter<String> adapter = new ArrayAdapter<String>(getActivity(),
android.R.layout.select_dialog_item, items);
AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setTitle("Seleccione la imagen");
builder.setAdapter(adapter, new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int item) { // pick from
// camera
if (item == 0) {
/**
* To take a photo from camera, pass intent action
* ‘MediaStore.ACTION_IMAGE_CAPTURE‘ to open the camera app.
*/
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
/**
* Also specify the Uri to save the image on specified path
* and file name. Note that this Uri variable also used by
* gallery app to hold the selected image path.
*/
mImageCaptureUri = Uri.fromFile(new File(Environment
.getExternalStorageDirectory(), "tmp_avatar_"
+ String.valueOf(System.currentTimeMillis())
+ ".jpg"));
intent.putExtra(MediaStore.EXTRA_OUTPUT,
mImageCaptureUri);
try {
intent.putExtra("return-data", true);
startActivityForResult(intent, PICK_FROM_CAMERA);
} catch (ActivityNotFoundException e) {
e.printStackTrace();
}
} else {
// pick from file
/**
* To select an image from existing files, use
* Intent.createChooser to open image chooser. Android will
* automatically display a list of supported applications,
* such as image gallery or file manager.
*/
Intent intent = new Intent();
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(Intent.createChooser(intent,
"Complete action using"), PICK_FROM_FILE);
}
}
});
builder.show();
}
public class CropOptionAdapter extends ArrayAdapter<CropOption> {
private ArrayList<CropOption> mOptions;
private LayoutInflater mInflater;
public CropOptionAdapter(Context context, ArrayList<CropOption> options) {
super(context, R.layout.crop_selector, options);
mOptions = options;
mInflater = LayoutInflater.from(context);
}
@Override
public View getView(int position, View convertView, ViewGroup group) {
if (convertView == null)
convertView = mInflater.inflate(R.layout.crop_selector, null);

if (item != null) {
((ImageView) convertView.findViewById(R.id.iv_icon))

return convertView;
}
return null;
}
}

if (resultCode != RESULT_OK)
return;
switch (requestCode) {
case PICK_FROM_CAMERA:
/**

*/
doCrop();
break;
case PICK_FROM_FILE:
/**
* After selecting image from files, save the selected path
*/
mImageCaptureUri = data.getData();
doCrop();
break;
case CROP_FROM_CAMERA:
Bundle extras = data.getExtras();
/**
* After cropping the image, get the bitmap of the cropped image and
* display it on imageview.
*/
if (extras != null) {
Bitmap photo = extras.getParcelable("data");
//Uri imageUri = extras.getParcelable("data");
profilePicture = photo;
iv_profile.setImageBitmap(photo);
IMAGE_STATUS = true;
}

f.delete();

}

* ‘com.android.camera.action.CROP‘.

*/
List<ResolveInfo> list = getPackageManager().queryIntentActivities(
intent, 0);
int size = list.size();

*/
if (size == 0) {
Toast.makeText(this, "Can not find image crop app",
Toast.LENGTH_SHORT).show();
return;
} else {

/**

* then app.
*/
if (size == 1) {
Intent i = new Intent(intent);
ResolveInfo res = list.get(0);
i.setComponent(new ComponentName(res.activityInfo.packageName,
res.activityInfo.name));
startActivityForResult(i, CROP_FROM_CAMERA);
} else {
/**
* If there are several app exist, create a custom chooser to
* let user selects the app.
*/
for (ResolveInfo res : list) {
final CropOption co = new CropOption();
co.title = getPackageManager().getApplicationLabel(
res.activityInfo.applicationInfo);
co.icon = getPackageManager().getApplicationIcon(
res.activityInfo.applicationInfo);
co.appIntent = new Intent(intent);
co.appIntent
.setComponent(new ComponentName(
res.activityInfo.packageName,
res.activityInfo.name));
cropOptions.add(co);
}
CropOptionAdapter adapter = new CropOptionAdapter(
getApplicationContext(), cropOptions);
AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setTitle("Choose Crop App");
builder.setAdapter(adapter,
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int item) {
startActivityForResult(
cropOptions.get(item).appIntent,
CROP_FROM_CAMERA);
}
});
builder.setOnCancelListener(new DialogInterface.OnCancelListener() {
@Override
public void onCancel(DialogInterface dialog) {
if (mImageCaptureUri != null) {
getContentResolver().delete(mImageCaptureUri, null,
null);
mImageCaptureUri = null;
}
}
});
AlertDialog alert = builder.create();
alert.show();
}
}
}
This is one of the parts where it turns red:
List<ResolveInfo> list = getPackageManager().queryIntentActivities(
intent, 0);
In this part when changing "Registration" by the name of the class it generates an error, the class is a fragment, and I have no idea which command to use
for (ResolveInfo res : list) {
final Registro.CropOption co = new Registro.CropOption();
co.title = getPackageManager().getApplicationLabel(
res.activityInfo.applicationInfo);
co.icon = getPackageManager().getApplicationIcon(
res.activityInfo.applicationInfo);
co.appIntent = new Intent(intent);
co.appIntent
.setComponent(new ComponentName(
res.activityInfo.packageName,
res.activityInfo.name));
cropOptions.add(co);
The parts that are in red tell me that the method can not be resolved.
