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>
I have the same problem with imageview resize while keyboard up i have solved with manifest android:windowSoftInputMode="adjustPan" and following is the layout example in my case

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:
No
ScrollView
at all in myactivity_main.xml
In
AndroidManifest.xml
added this attribute to the<activity android:name=".MainActivity" ...>
tag:
android:windowSoftInputMode="adjustResize"
- In
MainActivity.java
insideonCreate()
I addedgetWindow().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.
Er, let me see ... pictures first!

The related Java codes.

item.removeAllViews();

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"/>
