Question

Here’s a layout of my Activity XML:

For some reason I can’t see that button t the bottom of my screen.
Here’s the code:

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

<LinearLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content" >

    <LinearLayout
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:background="@drawable/bg_transparent"
        android:orientation="vertical"
        android:minHeight="44dip"
        android:minWidth="44dip" >

        <TextView
            android:id="@+id/lblNotesCount"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:layout_gravity="center_horizontal"
            android:textSize="18sp"
            android:textStyle="bold"
            android:textColor="@color/lblNotesCountColor" />

        <TextView
            android:id="@+id/lblTxtNotes"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:layout_gravity="center_horizontal"
            android:textSize="14sp"
            android:textStyle="bold"
            android:textColor="@color/lblNotesCountColor" />
    </LinearLayout>


    <TextView
        android:id="@+id/txtActivityListByCategory_Header"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_weight="1"
        android:ellipsize="end"
        android:gravity="center_vertical|center_horizontal"
        android:paddingLeft="2dp"
        android:singleLine="true"
        android:textStyle="bold"
        android:textColor="@color/color_WHITE" />

    <Button
        android:id="@+id/btnAddNote"
        style="?android:attr/buttonStyleSmall"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:background="@drawable/btn_new_note_selector"
        android:minHeight="44dip"
        android:minWidth="44dip" />
</LinearLayout>

<TextView
    android:id="@+id/emptyList"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:paddingLeft="2dp"
    android:text="@string/txtEmptyList"
    android:textAppearance="?android:attr/textAppearanceMedium"
    android:textColor="@color/emptyList" />

<ListView
    android:id="@+id/lstNotesByCategory"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:drawSelectorOnTop="false" >
</ListView>


<Button
    android:id="@+id/btnaBack"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:text="@string/btnBack" />

I tried to put the bottom TextView and ListView in a separate LinearLayout, I tried to give that button a layout_weight – nothing helped, I still don’t see that button, the LinearLayout goes till the bottom of the activity.

What is wrong here? Why don’t I see that button?

EDIT: Wrote down the entire XML code

Make your ListView’s android:layout_height="0dp" and android:layout_weight="1"

Like this:

<ListView
    android:id="@+id/lstNotesByCategory"
    android:layout_width="wrap_content"
    android:layout_height="0dp"
    android:layout_weight="1"
    android:drawSelectorOnTop="false" >
</ListView>

<Button
    android:id="@+id/btnaBack"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:text="@string/btnBack" />

This will make your ListView expand vertically till the borders of your Button.

Hope this helps
