I'm making a gallery application.
I have the code for that task, but I'd like to show all SD internal storage images. Only I can see a specific folder in my application, I understand why. This is a method that I found on the internet.

setContentView(R.layout.activity_main);
//location where photo saved
imagePath = Environment.getExternalStorageDirectory().toString() + "/DCIM/Camera";//I'd like to add more Folders, but it doesn't work
imageItems = new ArrayList<>();
getImages();
gridView = (GridView) findViewById(R.id.gridView);
gridAdapter = new GridViewAdapter(this, R.layout.grid_item, imageItems);

intent.putExtra("imagePath", imagePath);
startActivity(intent);
}
});
gridView.setAdapter(gridAdapter);
}
private List<String> getImages(){
new File(imagePath ).mkdirs();
File fileTarget = new File(imagePath);
File[] files = fileTarget.listFiles();
imageItems.clear();
if (files!=null){
for (File file: files){

In manifest I have declared permissions storage, parent activity.
Also, I'm add glide library on gradle.

You have spelling mistake on that error line.
It should be GitHubRepoAdapter, not GithubRepoAdapter.
I developed a vocabulary app where users can select their favorite words to a favourite section. I have two problems.
First, my code looks okay but when I choose a word from the list it doesn't show in the favorite section immediately. However, when I re-open the application it appears there.
The second problem is with the words which repeat in list with any run.
Here's my code :

Please help me to fix it, thanks
The constructor BoxOfficeMoviesAdapter(FindPeopleFragment,
ArrayList) is undefined
In your Fragment use getActivity() instead of this when you pass context to the constructor.
Change this
adapterMovies = new BoxOfficeMoviesAdapter(this, aMovies);
to
adapterMovies = new BoxOfficeMoviesAdapter(getActivity(), aMovies);
The method setContentView(int, FindPeopleFragment) is undefined for
the type FindPeopleFragment
setContentView(R.layout.activity_box_office, this);
must be removed
setContentview is a method of Activity class not Fragment
Change to
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.activity_box_office,container,false);
// rest of the code
return view;
}
Further getView() returns null
Change this
lvMovies = (ListView) getView().findViewById(R.id.lvMovies);
to
lvMovies = (ListView) view.findViewById(R.id.lvMovies);
The constructor Intent(FindPeopleFragment,
Class) is undefined
Finally Change this
Intent i = new Intent(FindPeopleFragment.this, BoxOfficeDetailActivity.class);
to
Intent i = new Intent(getActivity(), BoxOfficeDetailActivity.class);
You better read the Fragment documentation before going any further.
