Android: Footer in a ListView

2019-04-29 05:37发布

问题:

I have a listview as below

<?xml version="1.0" encoding="UTF-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent" android:layout_height="fill_parent"
    android:orientation="horizontal"
    android:background="#E6E7E2">
    <ImageView android:id="@+id/Thumbnail" android:layout_width="wrap_content"
        android:layout_height="wrap_content" android:src="@drawable/icon" />
    <TextView android:id="@+id/FilePath" android:layout_width="wrap_content"
        android:layout_height="wrap_content" 
        android:textColor="#E6E7E2"
        />
</LinearLayout>

and I have the footer as below

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
  xmlns:android="http://schemas.android.com/apk/res/android"
  android:orientation="vertical"
  android:layout_width="match_parent"
  android:layout_height="match_parent" android:layout_gravity="bottom">
    <LinearLayout android:layout_width="fill_parent" 
            android:layout_alignParentBottom="true" 
            android:layout_height="wrap_content"
            android:id="@+id/layoutfooterbutton" android:layout_gravity="bottom">

            <Button android:layout_weight=".30" android:layout_margin="2dp"
                android:layout_height="60dp" android:layout_width="100dp"
                android:textColor="#FFF" android:gravity="bottom|center"
                android:textSize="12dp" android:id="@+id/ButtonAudio" android:background="@drawable/vid_red"/>

            <Button android:layout_weight=".30" android:layout_height="60dp" android:layout_width="100dp"
                android:gravity="bottom|center" android:background="@drawable/redblank"
                android:textColor="#E6E7E2" android:id="@+id/ButtonBrowse" android:layout_marginTop="2dp"/>
            <Button android:layout_weight=".30" android:layout_margin="2dp"
                android:layout_height="60dp" android:layout_width="100dp"
                android:textColor="#FFF" android:gravity="bottom|center"
                android:textSize="12dp" android:background="@drawable/reddelete" android:id="@+id/ButtonDelete"/>

        </LinearLayout>
</RelativeLayout>

When I add the footer to the listview using

View header = getLayoutInflater().inflate(R.layout.header, null);
View footer = getLayoutInflater().inflate(R.layout.footer, null);
ListView lv = getListView();

// setting header for the list view
lv.addHeaderView(header);
lv.addFooterView(footer);
setListAdapter(new ArrayAdapter<String>(AudioListActivity.this, R.layout.row_audio,  R.id.label, db_results));

It goes to right below the last listview item. I want the footer to be in the bottom. How can I acheive it??

PS: Header perfectly sits on the top.

thanks for your time in advance.

回答1:

for your scenario i think you need something similar to this.

<RelativeLayout>
    <include android:id="@+id/header" layout="@layout/header" android:layout_width="fill_parent" android:layout_alignParentTop="true" />

    <include android:id="@+id/footer" layout="@layout/footer" android:layout_width="fill_parent" android:layout_alignParentBottom="true" /> 

    <ListView android:layout_below="@id/header" android:layout_above="@id/footer"/> 
</RelativeLayout>

It is working as intended. The footer view will be at the bottom of the list. In case you want to have something static at the bottom of the screen you need to use RelativeLayout with your footer as alignParentBottom and list over the top of it.

Ahh I found another similar question and the answer is also the same :)

Try this..

<ListView
        android:id="@+id/your_id"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        tools:listfooter="@layout/your_layout" />
