Option to rename albums in the Phimpme Android Application

In the Phimpme Android application, users can perform various operations on the albums available such as creating a zip file of the album, hiding an album and many more. However, one another useful functionality that has been added to the Phimpme Android application is the option to rename albums. So in this post, I will be discussing the implementation of the renaming functionality.

Step 1

First we need to add an option in the overflow menu to rename an album while we long-select an album or we are viewing photos inside a particular album. The option in the overflow menu can be added by integrating the following lines of code in the menu_albums.xml file(this file contains the xml code for overflow menu options provided for albums).

<item
android:id=”@+id/renameAlbum”
android:title=”@string/rename”
app:showAsAction=”never” />

Step 2

Now after the user selects the option in the overflow menu to rename the current viewing album, an alertdialog with an edittext would be displayed to the user to enter the new name for the album. The alertdialog containing the edittext has been implemented with the following lines of code.

<android.support.v7.widget.CardView
xmlns:android=”http://schemas.android.com/apk/res/android”
xmlns:app=”http://schemas.android.com/apk/vn.mbm.phimp.me”
android:layout_width=”match_parent”
android:layout_height=”wrap_content”
app:cardCornerRadius=”2dp”
android:id=”@+id/dialog_chose_provider_title”>
<LinearLayout
android:layout_width=”match_parent”
android:layout_height=”wrap_content”
android:orientation=”vertical”>
<TextView
android:id=”@+id/rename_title”
android:layout_width=”match_parent”
android:textColor=”@color/md_dark_primary_text”
android:layout_height=”wrap_content”
android:background=”@color/md_dark_appbar”
android:padding=”24dp”
android:text=”@string/rename_photo_action”
android:textSize=”18sp”
android:textStyle=”bold” />
<RelativeLayout
android:id=”@+id/container_edit_text”
android:layout_width=”match_parent”
android:layout_height=”match_parent”
android:orientation=”vertical”
android:padding=”24dp”/>
</LinearLayout>
</android.support.v7.widget.CardView>

The screenshot of the dialog to enter the new name is provided below.

Step 3

Finally, after retrieving the new name for the album entered by the user, the renameAlbum method is invoked by passing in the application context and new name as the parameters. Now inside the renameAlbum method, a new file path is created by the use of the getAlbumPathRenamed method of the StringUtils class and the current path of the album is changed to the new path generated earlier. Similarly path of each media inside the album is changed accordingly by the use of the method getPhotoPathRenamedAlbumChange of the StrinUtils class by looping through the media objects one by one. The lines of code implemented to perform the above-mentioned operations are provided below.

public boolean renameAlbum(final Context context, String newName) {
 found_id_album = false;
 boolean success;
 File newDir = new File(StringUtils.getAlbumPathRenamed(getPath(), newName));
 File oldDir = new File(getPath());
 success = oldDir.renameTo(newDir);
 if(success) {
    for (final Media m : media) {
       File from = new File(m.getPath());
       File to = new File(StringUtils.getPhotoPathRenamedAlbumChange(m.getPath(), newName));
       scanFile(context, new String[]{ from.getAbsolutePath() });
       scanFile(context, new String[]{ to.getAbsolutePath() }, new MediaScannerConnection.OnScanCompletedListener() {
          @Override
          public void onScanCompleted(String s, Uri uri) {
             if (!found_id_album) {
                id = MediaStoreProvider.getAlbumId(context, s);
                found_id_album = true;
             }
             Log.d(s, “onScanCompleted: “+s);
             m.setPath(s); m.setUri(uri.toString());
          }
       });
    }
    path = newDir.getAbsolutePath();
    name = newName;
 }
 return success;
}

This is how we have implemented the functionality to rename particular albums in the Phimpme Android application. To get the full source code, please refer to the Phimpme Android Github repository listed in the resource section below.
