MultiStateView

Android View that displays different content based on its state.
Based off of MeetMe/MultiStateView

The four different states the view can be in are:

• Content
• Empty
• Error
• Loading

Using MultiStateView

MultiStateView can be used the same as any other view by adding it as a layout file via XML

<com.kennyc.view.MultiStateView xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:id="@+id/multiStateView"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    app:msv_errorView="@layout/error_view"
    app:msv_emptyView="@layout/empty_view"
    app:msv_loadingView="@layout/loading_view"
    app:msv_viewState="loading">
    
      <ListView
        android:id="@+id/list"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        tools:listitem="@android:layout/simple_list_item_1" />

</com.kennyc.view.MultiStateView>

The attributes to set for MultiStateView are

<attr name="msv_loadingView" format="reference" />
<attr name="msv_emptyView" format="reference" />
<attr name="msv_errorView" format="reference" />
<attr name="msv_viewState" format="enum">
<attr name="msv_animateViewChanges" format="boolean" />

msv_loadingView is the view to be used for VIEW_STATE_LOADING
msv_emptyView is the view to be used for VIEW_STATE_EMPTY
msv_errorView is the view to be used for VIEW_STATE_ERROR
msv_viewState is the ViewState for the MultiStateView
msv_animateViewChanges is a flag to set whether the views should animate in and out when switching states. false by default
VIEW_STATE_CONTENT is determined by whatever is inside of the tags via XML. NOTE a Content view must be set for the view to function, this is by design.

To switch the state of MultiStateView, simply call

multiStateView.viewState = state: ViewState

or in java

multiStateView.setViewState(@NonNull ViewState state)

You can also get the View for the accompanying ViewState by calling

multiStateView.getView(state: ViewState):View?

or in java

@Nullable
public View getView(@NonNull ViewState state)
