List images in MediaStore.Images.Media

This exercise demonstrate how to list images in MediaStore.Images.Media.

Modify MainActivity.java extends ListActivity.

package com.example.androidlistimages;

import android.net.Uri;

import android.os.Bundle;

import android.provider.MediaStore;

import android.support.v4.content.CursorLoader;

import android.support.v4.widget.CursorAdapter;

import android.support.v4.widget.SimpleCursorAdapter;

import android.widget.ListAdapter;

import android.app.ListActivity;

import android.database.Cursor;

public class MainActivity extends ListActivity {

 //define source of MediaStore.Images.Media, internal or external storage

 Uri sourceUri = MediaStore.Images.Media.EXTERNAL_CONTENT_URI;

 //Uri sourceUri = MediaStore.Images.Media.INTERNAL_CONTENT_URI;

    @Override

    public void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);

        //setContentView(R.layout.activity_main);

        

        String[] from = {MediaStore.MediaColumns.TITLE};

        int[] to = {android.R.id.text1};

        CursorLoader cursorLoader = new CursorLoader(

          this, 

          sourceUri, 

          null, 

          null, 

          null, 

          MediaStore.Audio.Media.TITLE);

        

        Cursor cursor = cursorLoader.loadInBackground();

        

        ListAdapter adapter = new SimpleCursorAdapter(

          this, 

          android.R.layout.simple_list_item_1, 

          cursor, 

          from, 

          to, 

          CursorAdapter.FLAG_REGISTER_CONTENT_OBSERVER);

        setListAdapter(adapter);

    }

}

Remark:

Compare with my old exercise, "List audio media in MediaStore.Audio.Media" and "Start activity to play MediaStore.Video.Media by intent with action of Intent.ACTION_VIEW", both managedQuery(Uri uri, String[] projection, String selection, String[] selectionArgs, String sortOrder) and SimpleCursorAdapter(Context context, int layout, Cursor c, String[] from, int[] to) are deprecated. See how we use CursorLoader here.

Next:

- Get path of image in MediaStore.Images.Media from SimpleCursorAdapter

- List images in MediaStore.Images.Media, with multiple selection.

Compare with:

- Query Contacts database, display in ListView.
