Android Layout with ListView and Buttons

Question

Alright, this specific layout is just annoying me. And can't seem to find a way to have a listView, with a row of buttons at the bottom so that the listview doesn't extend over top of the buttons, and so the buttons are always snapped to the bottom of the screen. Here's what I want:

It seems like it should be so easy, but everything I've tried has failed. Any help?

Here's my current code:

    RelativeLayout container = new RelativeLayout(this);
    container.setLayoutParams(new RelativeLayout.LayoutParams(LayoutParams.FILL_PARENT,LayoutParams.FILL_PARENT));

    //** Add LinearLayout with button(s)

    LinearLayout buttons = new LinearLayout(this);

    RelativeLayout.LayoutParams bottomNavParams = new RelativeLayout.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
    bottomNavParams.addRule(RelativeLayout.ALIGN_PARENT_BOTTOM);
    bottomNavParams.addRule(RelativeLayout.CENTER_HORIZONTAL);
    buttons.setLayoutParams(bottomNavParams);


    ImageButton newLayer = new ImageButton(this);
    newLayer.setImageResource(R.drawable.newlayer);
    newLayer.setLayoutParams(new LinearLayout.LayoutParams(45, LayoutParams.FILL_PARENT));
    buttons.addView(newLayer);

    container.addView(buttons);

    //** Add ListView

    layerview = new ListView(this);

    RelativeLayout.LayoutParams listParams = new RelativeLayout.LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT);
    listParams.addRule(RelativeLayout.ABOVE, buttons.getId());

    layerview.setLayoutParams(listParams);

    container.addView(layerview);

The best way is a relative layout that sets the buttons below the listview. In this example the buttons are also in a linear layout because it is easier to put them side by side at an equal size.

<RelativeLayout android:id="@+id/RelativeLayout01" 
android:layout_width="fill_parent" 
android:layout_height="fill_parent">

<ListView android:id="@+id/ListView01" 
android:layout_alignParentTop="true"
android:layout_width="fill_parent" 
android:layout_height="fill_parent">
</ListView>

<LinearLayout android:id="@+id/LinearLayout01" 
android:layout_below="@+id/ListView01" 
android:layout_width="fill_parent" 
android:layout_height="wrap_content" 
android:layout_alignParentBottom="true">
<Button android:id="@+id/ButtonJoin" 
android:text="Join"
android:layout_width="fill_parent" 
android:layout_height="wrap_content"
android:layout_weight="1"
android:layout_alignParentBottom="true">
</Button>
<Button android:id="@+id/ButtonJoin" 
android:layout_alignRight="@id/ButtonCancel" 
android:layout_width="fill_parent" 
android:layout_height="wrap_content"
android:layout_weight="1"
android:text="Cancel"
android:layout_alignParentBottom="true">
</Button>
</LinearLayout>

</RelativeLayout>

I think this is what you are looking for.

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent" android:layout_height="fill_parent">

    <Button android:layout_width="fill_parent"
        android:layout_height="wrap_content" android:id="@+id/testbutton"
        android:text="@string/hello" android:layout_alignParentBottom="true" />

    <ListView android:layout_width="fill_parent"
        android:layout_height="fill_parent" android:id="@+id/list"
        android:layout_alignParentTop="true" android:layout_above="@id/testbutton" />

</RelativeLayout>

I know this post is rather old, but, to answer the original poster's question, the reason the code did not work was buttons.getId() returns -1. If you are going to do this, you need to set do something like call buttons.setId(10). If you do that, the code works just fine.

Answer 4

I had the same problem for ages.

The solution to keeping the ListView above the buttons, but preventing it from covering them up when the list is long, is to set android:layout_weight="1.0" on the ListView. Leave the layout_weight on the buttons unset so that they remain at their natural size, otherwise the buttons will get scaled. This works with LinearLayout.

There's an example in the Android ApiDemos: ApiDemos/res/layout/linear_layout_9.xml

Answer 5

I've tried the solutions out but when the ListView starts scolling I loose the button below :( There must be some other solution?
