Handles multiple display states for data-centric views

• Content state; shows the inner content of the View (as defined in XML)
• Loading state; shows a Loading state (as specified either via the loadingLayout attribute, or the default layout (res/layout/msv__loading.xml)

• For whatever View you want to switch out with MultiStateView, wrap the View in a MultiStateView node.
• In code, get your reference to the child of MultiStateView via MultiStateView#getContentView() and cast that value as needed. There's no good reason to put an android:id on the child View.

Example:

• Assuming you're starting with:

    <LinearLayout
        xmlns:android="https://schemas.android.com/apk/res/android"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:orientation="vertical" >
        
        <ListView
            android:id="@+id/list"
            android:layout_width="fill_parent"
            android:layout_height="match_parent" />
        
    </LinearLayout>
  

• You should end up with something like:

    <LinearLayout
        xmlns:android="https://schemas.android.com/apk/res/android"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:orientation="vertical" >
        
        <com.meetme.android.multistateview.MultiStateView
            android:id="@+id/list_container"
            android:layout_width="match_parent"
            android:layout_height="match_parent">
            
            <ListView
                android:layout_width="fill_parent"
                android:layout_height="match_parent" />
            
        </com.meetme.android.multistateview.MultiStateView>
        
    </LinearLayout>
  

  Example Notes 0. android:id="@+id/list" was moved from the ListView to the MultiStateView 0. It was also renamed to list_container to note that it now is the parent of the ListView 0. Any references in code should now use MultiStateView#getContentView() casted to ListView to reference the ListView child. There's no good reason to put an id on the ListView. See below.

• In code,

    ListView list = (ListView) findViewById(R.id.list);
  

• Becomes

    MultiStateView container = (MultiStateView) findViewById(R.id.list_container);
    ListView list = (ListView) container.getContentView();
  

• To control the state of the MultiStateView, use the MultiStateView#setState(State) method.

    container.setState(State.LOADING);
  

• By default, "Loading" indication uses the loading layout provided in the library (res/layout/msv__loading.xml). To customize, you can add the custom attribute msvLoadingLayout to the MultiStateView in XML with a reference to the layout to inflate.
