RelativeLayout weight

Question

In a layout resource XML, I have 3 RelativeLayout(s) which are inside a main RelativeLayout. The view will be shown vertically. These 3 RelativeLayout() are set next to each

Answer 1

You can use Horizontally oriented LinearLayout Manager in the Recycler View, and place each RelativeLayout in each item, of its Adapter.

The Link: How to build a Horizontal ListView with RecyclerView?

If your RelativeLayouts are set to a fixed width and height, that is to the size of the Screen, that you can get from DisplayMatrics, that will be OK.

If the contents of your RelativeLayouts are different, then you can use getItemViewType() method.

Please see: How to create RecyclerView with multiple view type?

Happy Coding :-)

Answer 2

RelativeLayout does not pay attention to android:layout_weight. (That's a property of LinearLayout.LayoutParams, but not of RelativeLayout.LayoutParams.)

You should be able to get the layout you want with a much simpler view hierarchy. It's not clear what you are trying to do, since the last two RelativeLayouts are empty. If you need a purely vertical organization, I'd suggest using LinearLayout instead of RelativeLayout.

EDIT Based on your edit, it looks like you want a horizontal layout of three compound views, each one clickable. I think something like the following will work:

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

    <!-- First column -->
    <LinearLayout
        android:id="@+id/firstColumn"
        android:orientation="vertical"
        android:gravity="center_horizontal"
        android:layout_width="0dp"
        android:layout_height="match_parent"
        android:layout_weight="1"
        >

        <ImageView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:src="..." />
        <TextView
            android:layout_width="wrap_content"
            android:layout_height="match_parent"
            android:text="text 1"
            . . . />
    </LinearLayout>

    <!-- Second column -->
    <LinearLayout . . . >
        . . .
    </LinearLayout>
</LinearLayout>

If the contents of the buttons aren't correct, you can replace the second-level LinearLayout views with RelativeLayout if that helps organize the layout better.

Answer 3

RelativeLayouts do not support weight. You need to use a LinearLayout as a parent container if you want to use weights.

Answer 4

Solution is very simple. I have been looking for weight distribution in relative layout.

It's a small trick for all these kind situations.

Use LinearLayout with android:orientation="horizontal"
