Question

I have CustomLayout class declared in a library customAndroidLibrary. This CustomLayout extends ViewGroup. Now I want to use this CustomLayout in my layout.xml which is in my project. I have included this library in my project.

CustomLayout class

package com.android.custom;
public class CustomLayout extends ViewGroup {
    .....
}

layout.xml

<com.android.custom.CustomLayout 
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/animation_layout"
    android:layout_width="match_parent"
    android:layout_height="match_parent">
</com.android.custom.CustomLayout>

MainActivity

package com.android.ui;    
public class MainActivity extends Activity{

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        // TODO Auto-generated method stub
        super.onCreate(savedInstanceState);
        setContentView(R.layout.layout);
    }
}

But it is throwing ClassNotFoundException.
Even it is not detecting my Activity also if I am using the custom view in layout.xml
If I am using simple TextView in layout.xml. Then it is not giving any error.

Solved it on my own.

<com.android.custom.CustomLayout   
    xmlns:android="http://schemas.android.com/apk/res/android"
    class="com.android.custom.CustomLayout"
    android:id="@+id/animation_layout"
    android:layout_width="match_parent"
    android:layout_height="match_parent">
</com.android.custom.CustomLayout>
