• 看代码

<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
             android:id="@id/rootView"
             android:orientation="vertical"
             android:layout_width="match_parent"
             android:layout_height="match_parent">



    <LinearLayout
        android:id="@+id/view_progress"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:gravity="center"
        android:layout_gravity="center"
        android:orientation="vertical"
        android:visibility="gone">

        <ProgressBar
            android:id="@+id/progress"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            />


        <TextView
            android:id="@+id/text_loading"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_marginTop="10dp"
            android:text="@string/loading"/>


    </LinearLayout>


    <FrameLayout
        android:id="@+id/view_content"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        >





    </FrameLayout>

    <LinearLayout
        android:id="@+id/view_empty"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:gravity="center"
        android:visibility="gone">


        <TextView
            android:id="@+id/text_tip"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="@string/empty_data"/>

    </LinearLayout>



</FrameLayout>

• **写个方法传入子布局id **

public void showView(int viewId) {
        for (int i = 0; i < rootView.getChildCount(); i++) {
            if (viewId == rootView.getChildAt(i).getId()) {
                rootView.getChildAt(i).setVisibility(View.VISIBLE);
            } else {
                rootView.getChildAt(i).setVisibility(View.GONE);
            }
        }
    }

• 使用

 public void showProgressView() {
        showView(R.id.view_progress);
    }

    public void showContentView() {
        showView(R.id.view_content);
    }

    public void showEmptyView() {
        showView(R.id.view_empty);
    }

• 怎么样 很简单吧
