Software Keyboard Resizes Background Image on Android

Software keyboard resizes background image on Android

Ok I fixed it by using

android:windowSoftInputMode="stateVisible|adjustPan"

entry inside <Activity > tag in manifest file. I think it was caused by having ScrollView inside the Activity.

Background image resizes every time keyboard is opened

Use this in the Manifest file.

android:windowSoftInputMode="adjustResize|stateAlwaysHidden"

and remove background image from Xml file and set it via Java code using below way

getWindow().setBackgroundDrawableResource(R.drawable.bg);

How to keep background image size when software keyboard show

After days of hardcore hacking I finally managed to construct a solution so advanced it might actually hurt to read it. I place an ImageView with the background behind the scrollview, and set scaleType="matrix" so it does not shrink when the keyboard is shown.

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:background="@color/black"
    >
    <ImageView
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:src="@drawable/mah_kewl_background"
        android:scaleType="matrix"
        />
    <ScrollView
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:fillViewport="true"
        >
        <RelativeLayout
            android:id="@+id/smsLayout"
            android:layout_width="fill_parent"
            android:layout_height="fill_parent"
            >
            <TextView
                android:layout_width="fill_parent"
                android:layout_height="wrap_content"
                android:text="PLUNX"
                />
        </RelativeLayout>
    </ScrollView>
</RelativeLayout>

Background Image gone compressed when keyboard is open

Your xml file is not correct ScrollView can not contain multiple child, i have resolved your problem.So Please follow my answer.

if you want to scroll only view not top image then use this one

    <?xml version="1.0" encoding="utf-8"?>
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:fillViewport="true"
    android:orientation="vertical">

    <androidx.constraintlayout.widget.ConstraintLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:background="@drawable/signup_bg"
        >
