Currently, I'm using **Android 4.4.2(API 19)** to run my project and I can see all the layout works perfectly. But when I use another device **Android 4.2(API 17)**, the layout is running and some of the buttons did not show (footer layout) !!! How can I solve this? Did you guys face this problem before? Thanks. 

**ListView Button**

These are the buttons in `xml` that did not show when I was using Android API 17. Just a normal button. They should show when there is a listView but they did not. 

```
 <?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"
    android:orientation="vertical">

    <TextView
        android:id="@+id/totalHours"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_toLeftOf="@+id/hours"
        android:paddingRight="10dp"
        android:text=" Total Hours : "
        android:textColor="@color/blue"
        android:textSize="16sp"/>

    <TextView
        android:id="@+id/hours"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignRight="@+id/submit"
        android:paddingRight="15dp"
        android:textColor="@color/blue"
        android:textSize="16sp"/>

    <Button
        android:id="@+id/submit"
        android:layout_width="334dp"
        android:layout_height="61dp"
        android:layout_alignParentLeft="true"
        android:layout_below="@+id/addClaims1"
        android:layout_marginLeft="15dp"
        android:text="submit"
        android:theme="@style/ButtonTheme"/>

    <Button
        android:id="@+id/addClaims1"
        android:layout_width="334dp"
        android:layout_height="61dp"
        android:layout_marginTop="10dp"
        android:layout_below="@id/totalHours"
        android:layout_marginLeft="15dp"
        android:text="add claims"/>

</RelativeLayout>
