Loading all the images from gallery into the Application in android

Question

I am creating an application wherein I need all the images in the gallery into my application that has a girdview in it. I want all the images from all the folders to appear in the gridview.

String[] proj = { MediaStore.Images.Media.DATA, MediaStore.Images.Media._ID }; actualimagecursor = managedQuery(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, proj,                       null, null, MediaStore.Images.Media.DEFAULT_SORT_ORDER);  actual_image_column_index = actualimagecursor.getColumnIndexOrThrow(MediaStore.Images.Media._ID); actualimagecursor.moveToPosition(position); String i = actualimagecursor.getString(actual_image_column_index); 

I have added this code into my code but i get only the sd card images no other folder images are obtained. How can i get all the images from the gallery?

Thanks in advance.

Working solution with the help of Glide. Bonus part is Glide will auto play Gif .

import java.util.ArrayList;  import android.app.Activity; import android.database.Cursor; import android.net.Uri; import android.os.Bundle; import android.provider.MediaStore; import android.provider.MediaStore.MediaColumns; import android.view.View; import android.view.ViewGroup; import android.widget.AdapterView; import android.widget.AdapterView.OnItemClickListener; import android.widget.BaseAdapter; import android.widget.GridView; import android.widget.ImageView; import android.widget.Toast;  import com.bumptech.glide.Glide;  /**  * The Class GallarySample.  */ public class GallarySample extends Activity {      /** The images. */     private ArrayList<String> images;     @Override     public void onCreate(Bundle savedInstanceState) {         super.onCreate(savedInstanceState);         setContentView(R.layout.gallery_activity);          GridView gallery = (GridView) findViewById(R.id.galleryGridView);          gallery.setAdapter(new ImageAdapter(this));          gallery.setOnItemClickListener(new OnItemClickListener() {              @Override             public void onItemClick(AdapterView<?> arg0, View arg1,                     int position, long arg3) {                 if (null != images && !images.isEmpty())                     Toast.makeText(                             getApplicationContext(),                             "position " + position + " " + images.get(position),                             300).show();                 ;              }         });      }      /**      * The Class ImageAdapter.      */     private class ImageAdapter extends BaseAdapter {          /** The context. */         private Activity context;          /**          * Instantiates a new image adapter.          *          * @param localContext          *            the local context          */         public ImageAdapter(Activity localContext) {             context = localContext;             images = getAllShownImagesPath(context);         }          public int getCount() {             return images.size();         }          public Object getItem(int position) {             return position;         }          public long getItemId(int position) {             return position;         }          public View getView(final int position, View convertView,                 ViewGroup parent) {             ImageView picturesView;             if (convertView == null) {                 picturesView = new ImageView(context);                 picturesView.setScaleType(ImageView.ScaleType.FIT_CENTER);                 picturesView                         .setLayoutParams(new GridView.LayoutParams(270, 270));              } else {                 picturesView = (ImageView) convertView;             }              Glide.with(context).load(images.get(position))                     .placeholder(R.drawable.ic_launcher).centerCrop()                     .into(picturesView);              return picturesView;         }          /**          * Getting All Images Path.          *          * @param activity          *            the activity          * @return ArrayList with images Path          */         private ArrayList<String> getAllShownImagesPath(Activity activity) {             Uri uri;             Cursor cursor;             int column_index_data, column_index_folder_name;             ArrayList<String> listOfAllImages = new ArrayList<String>();             String absolutePathOfImage = null;             uri = android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI;              String[] projection = { MediaColumns.DATA,                     MediaStore.Images.Media.BUCKET_DISPLAY_NAME };              cursor = activity.getContentResolver().query(uri, projection, null,                     null, null);              column_index_data = cursor.getColumnIndexOrThrow(MediaColumns.DATA);             column_index_folder_name = cursor                     .getColumnIndexOrThrow(MediaStore.Images.Media.BUCKET_DISPLAY_NAME);             while (cursor.moveToNext()) {                 absolutePathOfImage = cursor.getString(column_index_data);                  listOfAllImages.add(absolutePathOfImage);             }             return listOfAllImages;         }     } } 

Layout file for gridView

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"     xmlns:tools="http://schemas.android.com/tools"     android:layout_width="match_parent"     android:layout_height="match_parent" >      <GridView         android:id="@+id/galleryGridView"         android:layout_width="match_parent"         android:layout_height="wrap_content"         android:columnWidth="280dp"         android:gravity="center"         android:horizontalSpacing="2dp"         android:numColumns="2"         android:padding="2dp"         android:stretchMode="columnWidth"         android:verticalSpacing="2dp" >     </GridView>  </RelativeLayout> 

UPDATE 2019 with Kotlin and LoderManager:

** 2) Use LoderManager to load async load images.**

Implement LoaderManager.LoaderCallbacks<Cursor> in your activity or Fragment class

Override LoaderCallbacks this:

private val IMAGE_LOADER_ID = 1 private val listOfAllImages = ArrayList<String>()    override fun onCreateLoader(p0: Int, p1: Bundle?): Loader<Cursor> {      val uri = MediaStore.Images.Media.EXTERNAL_CONTENT_URI     val projection = arrayOf(MediaColumns.DATA, MediaStore.Images.Media.BUCKET_DISPLAY_NAME)     val selection: String? = null     //Selection criteria     val selectionArgs = arrayOf<String>()  //Selection criteria     val sortOrder: String? = null      return CursorLoader(             activity!!.applicationContext,             uri,             projection,             selection,             selectionArgs,             sortOrder) }  override fun onLoadFinished(loader: Loader<Cursor>, cursor: Cursor?) {      cursor?.let {         val columnIndexData = it.getColumnIndexOrThrow(MediaColumns.DATA);          while (it.moveToNext()) {              listOfAllImages.add(it.getString(columnIndexData));         }     } }   override fun onLoaderReset(loader: Loader<Cursor>) { } 

Lastly on onCreate method init loader:

 loaderManager.initLoader(IMAGE_LOADER_ID,                 null,                 this) 

3) Using Kotlin Coroutine & ViewModel

implementation 'androidx.core:core-ktx:1.0.2'

implementation 'org.jetbrains.kotlinx:kotlinx-coroutines-core:1.3.0-M2'

implementation "org.jetbrains.kotlinx:kotlinx-coroutines-android:1.3.0-M2"

Create View Model With Coroutine Context

  /**    * Use Coroutines To Load Images    */    class ImageViewModel : ViewModel(), CoroutineScope {      private val job = Job()     override val coroutineContext: CoroutineContext         get() = job + Dispatchers.Main      private var imagesLiveData: MutableLiveData<List<String>> = MutableLiveData()     fun getImageList(): MutableLiveData<List<String>> {         return imagesLiveData     }      /**      * Getting All Images Path.      *      * Required Storage Permission      *      * @return ArrayList with images Path      */     internal fun loadImagesfromSDCard(): ArrayList<String> {         val uri: Uri = android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI         val cursor: Cursor?         val column_index_data: Int         val column_index_folder_name: Int         val listOfAllImages = ArrayList<String>()         var absolutePathOfImage: String? = null          val projection = arrayOf(MediaStore.MediaColumns.DATA, MediaStore.Images.Media.BUCKET_DISPLAY_NAME)          cursor = AppController.globalContentResolvere!!.query(uri, projection, null, null, null)          column_index_data = cursor!!.getColumnIndexOrThrow(MediaStore.MediaColumns.DATA)         column_index_folder_name = cursor!!             .getColumnIndexOrThrow(MediaStore.Images.Media.BUCKET_DISPLAY_NAME)         while (cursor!!.moveToNext()) {             absolutePathOfImage = cursor!!.getString(column_index_data)             listOfAllImages.add(absolutePathOfImage)         }         return listOfAllImages     }      fun getAllImages() {         launch(Dispatchers.Main) {             imagesLiveData.value = withContext(Dispatchers.IO) {                 loadImagesfromSDCard()             }         }     } } 

And then use viewModel

 val imageViewModel = ViewModelProviders.of(this).get(ImageViewModel::class.java)      imageViewModel.getImageList().observe(this, Observer<List<String>> { listOfImage ->         imageWidgetStatus.text = """ Found ${listOfImage.size} Images"""       // load images     imageViewModel.getAllImages() 

Answer 2

You are using MediaStore.Images.Media.EXTERNAL_CONTENT_URI which is only the external storage.For the internal there is MediaStore.Images.Media.INTERNAL_CONTENT_URI. You can use a MergeCursor to combine both query results.
