How to customize proportions in layouts on Android?

In Android, you can use the weight attribute to define the proportions of different elements in a layout.

Firstly, in the layout file create a parent container (such as LinearLayout) to contain the child elements that need to have weights set. Then, set a weight value for each child element.

For example, to create a horizontal layout where one element is twice the width of another element, you can set it up like this:

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

    <View
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_weight="1"/>

    <View
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_weight="2"/>

</LinearLayout>

In the given example, the first View element has a weight value of 1, while the second View element has a weight value of 2. Since the width is set to 0dp, their width will be distributed based on the weight values. In this scenario, the width of the first element will be half of the second element.

By adjusting the weight values, you can customize the proportions between different elements as needed.
