Android ListView 設定 FootView

當尋找Device或列出IP時, 使用ListView時, 想在List 列表底下顯示”搜尋中或讀取中”的提示時

可使用FootView來達成.

Step 1: 新增footview.xml

在res/layout增加footview.xml

footview.xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
                android:layout_width="match_parent"
                android:layout_height="match_parent">
    <ImageView
            android:id="@+id/list_foot"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_centerInParent="true"
            android:src="@drawable/loading"/>
</RelativeLayout>

Step 2: ListView add footview

MainActivity.java

ListView mDeviceList = (ListView) findViewById(R.id.device_list);
mDeviceList.setOnItemClickListener(this);
View footerView = ((LayoutInflater)this.getSystemService(LAYOUT_INFLATER_SERVICE))
        .inflate(R.layout.listview_foot, null, false);
mDeviceList.addFooterView(footerView);

Step 3: 取消FootView的Divider

main_layout.xml

<ListView
        android:id="@+id/device_list"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_below="@id/title"
        android:layout_above="@+id/find_devices"
        android:layout_margin="5dp"
        android:divider="@color/colorPrimary"
        android:dividerHeight="1dp"
        android:footerDividersEnabled="false"/>
