I'm trying to create a simple Activity in Android where user can easily sign up to my sqlite database. I want to give the chance to select some kind of avatar stored in my drawable folder and set that image in an ImageView.
The problem is that when i click on mi Set Avatar button i can only see a blank fragment without the content i want.
Here's my code :
Row Model
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="horizontal"
android:layout_margin="16dp"
>
<ImageView
android:id="@+id/avatar_img"
android:layout_width="0dp"
android:layout_weight="0.9"
android:layout_height="50dp"
android:src="@drawable/user" />
<TextView
android:id="@+id/avatar_title"
android:text="Avatar"
android:layout_weight="2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textSize="20sp"
android:layout_marginLeft="5dp"/>
RegisterActivity layout file:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
