Should I create different layouts (xml files) for different Android mobile phones

Question

Do I have to create different layout folders to store my xml layout files. Support my app on different screen sizes?

I developed the application, and when adding drawings, it automatically creates different sizes, such as xdpi ldpi and more, but xml-layout files are not created automatically to support different screen sizes. I have to do it? and I will also edit the manifest file to support different sizes with the support tag. and it's all? And he will also support my landscape or portrait mode. Please confirm. I am new to stack development and Android.

Edit: I believe that different layout files in different folders .. will be just a copy of each other, only with a message about changing the folder name displayed in the code

res/layout/my_layout.xml             // layout for normal screen size ("default")
res/layout-small/my_layout.xml       // layout for small screen size
res/layout-large/my_layout.xml       // layout for large screen size
res/layout-xlarge/my_layout.xml      // layout for extra large screen size
res/layout-xlarge-land/my_layout.xml // layout for extra large in landscape orientation

This is my layout xml file:

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:id="@+id/content_main"
    android:layout_width="match_parent"
    android:layout_height="match_parent"

    app:layout_behavior="@string/appbar_scrolling_view_behavior"
    tools:showIn="@layout/app_bar_main"
    tools:context="com.example.root.meeransunday.MainActivity">


    <Button
        android:id="@+id/button1"
        android:layout_width="200dp"
        android:layout_height="90dp"
        android:text="Send Mobile"
        android:drawableLeft="@mipmap/sms"
        android:layout_alignParentBottom="true"
        android:layout_marginRight="-1dp"
        android:layout_marginLeft="-3dp"
        android:layout_marginBottom="-4dp"
        android:onClick="message"/>
    <Button
        android:id="@+id/button2"
        android:layout_width="200dp"
        android:layout_height="90dp"
        android:text="QR Code"
        android:drawableLeft="@mipmap/qr"
        android:layout_marginLeft="190dp"
        android:layout_marginRight="-20dp"
        android:layout_marginBottom="-4dp"
        android:layout_alignParentBottom="true"
        android:onClick="scan"
        />
<TextView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_marginTop="30dp"
    android:layout_centerHorizontal="true"
    android:text="        My Account Balance"
    android:textColor="#0D47A1"
    />
    <TextView
        android:text="PKR 1527.87"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginTop="40dp"
        android:layout_centerHorizontal="true"
          android:drawableLeft="@mipmap/money"
        android:textSize="35sp"
        android:id="@+id/textView2"

        />
</RelativeLayout>

Manifest file:

<supports-screens android:smallScreens="true"
            android:normalScreens="true"
            android:largeScreens="true"
            android:xlargeScreens="true"
            android:anyDensity="true"
            android:resizeable="true"/>

but it does not work on a 4-inch screen.

Answer 1

If the layout is the same, there is no need to create multiple layout files, you must use different file sizes to adjust the size of your elements.

If you want your application to look different on an hdpi device than on xxxhdpi, or if you have a mobile version and a tablet version on the screen, you should use several layout files.
