I have been working on an Android Application project recently, and I've notice that some of my code IDs within a XML file will not register within the R file, and I have not been able to access the IDs within my classes. The code within the XML file will look like:

<?xml version="1.0" encoding="utf-8"?>

<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent">

<ImageView android:layout_height="250dp"
android:layout_gravity="center"
android:src="@drawable/icon" 
android:id="@+id/ivReturnedPic" 
android:layout_width="250dp"></ImageView>

<ImageButton android:layout_height="wrap_content" 
android:src="@drawable/icon" 
android:id="@+id/ibTakePic" 
android:layout_width="125dp"
android:layout_gravity="center"></ImageButton>

<Button android:text="Set Wallpaper" 
android:id="@+id/bSetWall" 
android:layout_width="125dp" 
android:layout_height="wrap_content"
android:layout_gravity="center"></Button>

</LinearLayout>

</LinearLayout>

None of theses IDs will register within the resource file.

go project>clean

Check that all of your xml files and resources ie images, videos etc. have no capitals in the title.

If that doesn't work you can delete the R file, and then go project>clean

After cleaning the project, the errors on the XML file have disappeared. However, the R file is gone, and the files still are not referencing the IDs set up the XML files. Can you help?

Just create a new class-file in gen -> *package name* and name it "R"
Then try to rebuild it again.
Sometimes you have to do this several times.
