How to prevent Soft Keyboard from resizing background image

I have a typical listview with an edittext and a button at the bottom of the activity.

When I click onto the edittext, the soft keyboard appears, I am able to scroll the items in the listview but it re-sizes my background image.

I have tried android:windowSoftInputMode="adjustResize" but no difference.

I have tried android:windowSoftInputMode="adjustPan". The image does not get squashed, the whole layout shifts upwards and I lose the titl开发者_运维百科e bar. I can only scroll the list if the list items exceed the layout size.

Basically, I want to maintain the title bar, retain the background image without re-sizing and allow scrolling of list items. Anyone managed to do this? Thanks!

for listview you need to use

android:isScrollContainer="false"

and add this to your activity in manifest.xml

android:windowSoftInputMode="adjustPan"

I have tried so may solutions for solving this problem. android:windowSoftInputMode="adjustPan" will make your whole screen shift with keyboard. Generally we have a title of the screen on the top. Using this flag it will also go out of the visible area, which make bad user experience. I use android:windowSoftInputMode="adjustResize" This will resize the whole screen but it will cause the same problem @Maurice state in the question.

So here is my final solution:

In Manifest

android:windowSoftInputMode="adjustResize|stateAlwaysHidden"

In XMl

Dont Set any background here.And keep your view under ScrollView

In Java

You need to set the background to window:

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

Go to the Androidmanifest.xml and:

activity name="activityname" android:windowSoftInputMode="stateVisible|adjustPan"

There is no way to prevent the soft keyboard from resizing a background image.

Use this scaleType(matrix) and prepare a suitable image.

Use android:windowSoftInputMode="adjustResize" and simply wrap your background ImageView in a ScrollView.

<ScrollView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:scrollbars="none"
    android:overScrollMode="never">
    <ImageView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"/> 
</ScrollView>

if there is possible to load image dynamically you can resize image with picaaso while load in imageview

Use ImageView with fill_parent and centerCrop attributes in RelativeLayout. Like this;

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    >
    <ImageView
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:src="@drawable/yazisma_arka_plan"
        android:scaleType="centerCrop"
        />
    <ListView
        android:id="@+id/messages_view"
        android:layout_width="fill_parent"...

I read a lot of answers over StackOverflow and took some from many to make my app works:

1. No ScrollView at all in my activity_main.xml

2. In AndroidManifest.xml added this attribute to the

   <activity android:name=".MainActivity" ...>

tag:

android:windowSoftInputMode="adjustResize"

3. In MainActivity.java inside onCreate() I added getWindow().setBackgroundDrawableResource(R.drawable.app_bg);

It works for me when all the other solutions I've tried didn't. If you got up to here, I hope it'll work for you too.

The AndroidManifest part.

    <activity
        android:name=".ui.activity.ActLogin"
        android:label="@string/str_login"
        android:theme="@style/myTheme"
        />
    <!--android:windowSoftInputMode="adjustResize"-->

The style part.

<style name="myTheme" parent="@android:style/Theme.Light.NoTitleBar">
    <item name="android:windowTranslucentStatus">true</item>
</style>

---

This code doesn't work for me:

android:windowSoftInputMode="adjustResize"

But this does work:

android:windowSoftInputMode="adjustPan"

---

For those who aren't get it:

double ckeck if your xml already has a @drawable setted (this was the error for me, i was setting via android manifest but it was already setted on the root of xml)

after that create a theme style with background:

<style name="AppThemeWBackgroundG" parent="AppTheme">
        <item name="android:windowBackground">@drawable/background_com_gradiente</item>
</style>

Then in your activity on AndroidManifest.xml:

<activity
   android:name=".TelaLoginFuncionario"
   android:windowSoftInputMode="adjustResize|stateAlwaysVisible"
   android:theme="@style/AppThemeWBackgroundG"
    android:fitsSystemWindows="true"
/>

and that's it: the activity enter in a screen with the keyboard up, resizing up the items and the background stays at normal size

---

all you need to do is to set the background gravity to the top

<item android:drawable="@drawable/background_image" android:gravity="top"/>
