How do I align views at the bottom of the screen?

How to Align Views at the Bottom of the Screen in Android 📱💻💡

Have you ever struggled with aligning your views at the bottom of the screen in your Android app? You're not alone! It can be quite challenging to achieve the desired layout, especially when the first item in a layout fills all available space, leaving no room for other items. But fret not, we've got you covered! In this post, we'll explore a common issue related to aligning views at the bottom of the screen and provide you with an easy solution using RelativeLayouts. Let's dive in! 🏊‍♂️

The Problem 😕

Let's take a look at an example layout code:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent">

    <TextView android:text="@string/welcome"
        android:id="@+id/TextView"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content">
    </TextView>

    <LinearLayout android:id="@+id/LinearLayout"
        android:orientation="horizontal"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:gravity="bottom">

        <EditText android:id="@+id/EditText"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content">
        </EditText>

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

    </LinearLayout>

</LinearLayout>

The issue with this layout is that the desired result is to have the submit button and the text entry field fixed at the bottom, while the TextView should fill the remaining space. However, when we set the TextView's height to fill_parent, it leaves no room for the button and entry field.

The Solution 🙌

To achieve the desired layout, we can utilize RelativeLayouts. Here's an updated version of the layout code:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent">

    <TextView
        android:text="@string/welcome"
        android:id="@+id/TextView"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:layout_alignParentTop="true">
    </TextView>

    <RelativeLayout
        android:id="@+id/InnerRelativeLayout"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentBottom="true">

        <Button
            android:text="@string/label_submit_button"
            android:id="@+id/Button"
            android:layout_alignParentRight="true"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content">
        </Button>

        <EditText
            android:id="@+id/EditText"
            android:layout_width="fill_parent"
            android:layout_toLeftOf="@id/Button"
            android:layout_height="wrap_content">
        </EditText>

    </RelativeLayout>

</RelativeLayout>

Now, we have two RelativeLayouts: the outer one remains the same, while the inner one is aligned to the bottom. By using relative positioning attributes such as layout_alignParentTop, layout_alignParentRight, and layout_toLeftOf, we can achieve the desired layout without any conflicts.

And there you have it! 🎉 Your views are now aligned at the bottom of the screen, with the TextView filling the remaining space.

Your Turn! ⚡️

Now that you have learned how to align views at the bottom using RelativeLayouts, give it a try in your own projects! Play around with the positioning attributes to get the perfect layout for your needs. And if you encounter any issues or have any questions, feel free to leave a comment below.
