A class used for control Layout status.

• quickly,convenient
• not need to modify xml
• not deepen the UI level,lead to over-drawing and dropped frames
• can custom layout
• can set listener
• can use any View,not only limited to ListView or RecycleView
• auto get layout params from replaced View,eg: size, position, id and so on
• does not destroy the dependencies between the replaced View and other View (especially the relative layout)

If you want to set a empty View in your ListView, you can do this:

<LinearLayout>
    <ListView
        android:id="@+id/list_sms_history"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:scrollingCache="false" />
    <TextView
        android:id="@+id/noSmsData"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:gravity="center_vertical|center_horizontal"
        android:text="暂无数据" />
</LinearLayout>

callLogList = (ListView)findViewById(R.id.call_log_list);
myEmpty=(TextView)findViewById(R.id.myEmptyText);
callLogList.setEmptyView(myEmpty);

If you want to set a empty View in your RecycleView, you must write more code.
We should set emptyView or set View's visible or gone in xml or java file.
And we will mad when we set thousands of empty Views. Because we didn't do it at the beginning of the project.
This is not the worst, if producter or designer want to add loading and error View, and change the empty View,
The UI is so complex that you should fix xml and code one bye one.

The LayoutStatusControl can help you set a empty View quickly and convenient.

//1: init class. R.id.tv_content is the View's id which you want to replace
lyControl = new LayoutStatusControl(this, R.id.tv_content);
//2: set empty View, parameter is layout id or a View
lyControl.setEmptyView(R.layout.View_nodata);
//3: show
lyControl.showEmptyView();

show loading, empty, error or success View

lyControl.showLoadingView();
lyControl.showEmptyView();
lyControl.showErrorView();
lyControl.showSuccessView();

custom status View

lyControl.setEmptyView();
lyControl.setErrorView();
lyControl.setLoadingView();
