Make View Scrollable because hidden text - android

I have an Activity with 2 LinearLayouts vertical in the screen and 1-2 buttons in the bottom right corner.
Depending on the length of the LinearLayouts it could happen that the text in the Layouts is hidden from the Button. Hence i would like to make the Activity always scrollable that the User is able to drag the LinearLayouts a bit up and read the text.
Here is a little Visualization:
I tried it with some solutions i found on the web but its not working:
first try:
<ConstraintLayout>
<LinearLayout>...</LinearLayout>
<LinearLayout>...</LinearLayout>
<Button>...</Button>
<ConstraintLayout>
second try:
<RelativeLayout 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">
<ScrollView
android:layout_width="match_parent"
android:layout_height="match_parent">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<LinearLayout>...</LinearLayout>
<LinearLayout>...</LinearLayout>
</LinearLayout>
</ScrollView>
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true">
<Button .... />
</RelativeLayout>
</RelativeLayout>

Try to add Padding Bottom
<LinearLayout
android:padding_bottom="50dp"
/>

Android ExpandableListView not showing

So I have a ExpandableListView in my layout, but for some reason It is showing only some part of it when I run the app. Yes, it's "some" part - actually almost the enture first GroupView.
If I set a fixed height to the list at android:layout_height="some dp", instead of android:layout_height="match_parent" I can see the whole list. But, If I have too many group view's and child view's, again, I can see only some part of it (as the height is fixed).
I've tried to put the expandable list inside a LinearLayout, have tried to set android:layout_height="wrap_content", and so on, but without success.
How can I solve this?
Thank you,

Android - position layout at bottom of screen always in the foreground

My xml file is like following:
<LinearLayout>
<ScrollView>
<LinearLayout>
</LinearLayout>
</ScrollView>
</LinearLayout>
First LinearLayout has android:layout_height="match_parent", all others android:layout_height="wrap_content". How to create a layout at bottom of screen always in the foreground with an imageview?
This is best done with a relative layout. Relative layout elements stack on top of each other unless you position them relative to each other. For instance, if you had two image views and did position them, the second image view would be placed on top of the first one.
Here is an example to get you started:
<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">
<ScrollView
android:layout_width="match_parent"
android:layout_height="match_parent">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"/>
</ScrollView>
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:layout_alignParentBottom="true"
android:contentDescription="#string/YOUR_CONTENT_DESC"
android:scaleType="fitXY"
android:src="#drawable/ic_launcher"/>
</RelativeLayout>
you could set the gravity of the linear layout to bottom.
android:layout_gravity="bottom"
When your creating your XML document order does matter. So for example:
<ImageView/>
<LinearLayout/>
The LinearLayout will be placed in front of the ImageView.
Try this way,hope this will help you to solve your problem with another one alternative.
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<ScrollView
android:layout_width="match_parent"
android:layout_height="match_parent">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
</LinearLayout>
</ScrollView>
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/ic_launcher"
android:adjustViewBounds="true"
android:layout_gravity="bottom|center_horizontal"/>
</FrameLayout>

ScrollView throws bottom views out

I have a LinearLayout with a ScrollView inside and a checkbox underneath the scrollview. Whenever i put alot of text in the scrollview, it will expand through the whole screen and kick out the bottom checkbox view. How do i prevent that from happening?
Basically, i want the checkbox to always be right underneath the scrollview. I also want the scrollview to shrink and expand depending on its text. When theres alot of text inside, it should expand to the point where the checkbox is still visible at the bottom of the screen.
It should look like this:
Where the filled ScrollView should have a scroller if the text is too much, rather than kicking out the checkbox from the screen
Help!
My layout looks like:
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<ScrollView
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<!-- TextView inside --->
</ScrollView>
<RelativeLayout
android:layout_width="fill_parent"
android:layout_height="80dp"
android:gravity="top"
android:orientation="horizontal" >
<!-- CheckBox inside --->
</RelativeLayout>
</LinearLayout>
Dont worry about the syntax, or all the stuff that are inside, I wrote this quick because the code inside is really long and unnecessary!
Try this layout :
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<ScrollView
android:layout_width="wrap_content"
android:layout_height="0dp"
android:layout_weight="1">
<!-- TextView inside --->
</ScrollView>
<!-- CheckBox Here --->
</LinearLayout>
Let's start simple. Try replacing your parent LinearLayout with a RelativeLayout. If this doesn't work, you may have to fix the height of ScrollView to some fixed height using weight, or pixels (which is non-ideal):
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<ScrollView
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<!-- TextView inside --->
</ScrollView>
<RelativeLayout
android:layout_width="fill_parent"
android:layout_height="80dp"
android:gravity="top"
android:orientation="horizontal" >
<!-- Stuff inside --->
</RelativeLayout>
</RelativeLayout>
Define a fixed size to your ScrollView. As bigger as the text becomes, the scroll is defined to that size (like layout_height="100dp")
UPDATE
Try something like this
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<ScrollView
android:layout_width="match_parent"
android:layout_height="200dp" >
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<!-- TextView's inside - -->
</LinearLayout>
</ScrollView>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical" >
<!-- CheckBox's inside - -->
</LinearLayout>
</LinearLayout>

Clicking on Edittext inside nested Scrollview scrolls outer scrollview

I have a parent horizontalScrollview that contains various layouts. In one particular layout there is a scrollview. Inside that scrollview there is edittext.
Now when I click on any edittext for input, the horizontal scrollview automatically scrolls the screen to some other layout and I am not able to see the current active layout(containing scrollview).
I know nested scrollviews is a bad coding practice but I can not change it in this case as there will be large amount of rework. Is there any workaround for this.
Following is the xml code for main layout containing horizontalscrollview:-
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<HorizontalScrollView
android:id="#+id/CloudHScrollView"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
</RelativeLayout>
and following is the code for one of the child layouts that is inserted later at some stage. This layout contains the scrollview which has edittexts:-
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<ScrollView
android:id="#+id/scrollview"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginTop="0dp"
android:background="#drawable/blueoverlay"
android:fillViewport="true" >
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
android:paddingBottom="300dp"
android:paddingTop="90dp" >
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical" >
<EditText
android:id="#+id/edittext"
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_weight="1"
android:background="#null"
android:gravity="right"
android:singleLine="true"
android:textAppearance="?android:attr/textAppearanceSmall"
android:textColor="#android:color/black" />
</LinearLayout>
</LinearLayout>
</ScrollView>
I'm not sure if this will work, but you can try extending outer ScrollView class and handle its onScroll events on your own.

I had the same issue, solved it by adding the following to AndroidManifest.xml file for the corresponding activity.
android:windowSoftInputMode="adjustResize"

Android ScrollView and buttons at bottom of the screen

I want to implement this: A ScrollView that contains many elements (ImageViews, TextViews, EditTexts etc) and then after the ScrollView some buttons (which are custom ImageViews) that appear always exactly at the bottom of the screen.
If I use the android:fillViewport="true" attribute, then if the elements of the ScrollView are too big to fit in the screen size the buttons get invisible . If I use the android:Weight=1 attribute then the ScrollView gets only 50% of the Screen when the screen is big and it can fit (I want the buttons to take a small percentage, about 10%). If I set the android:Weight to bigger values then the buttons appear very small.
Please help! Maybe it is something simple that I overlooked but I’ve been banging my head for hours!
Just created and tested it. Looks like you want.
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<LinearLayout
android:id="#+id/buttons"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal"
android:gravity="center"
android:layout_alignParentBottom="true">
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Custom Button1"/>
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Custom Button2"/>
</LinearLayout>
<ScrollView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_above="#id/buttons">
<!--Scrollable content here-->
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<TextView
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:text="test text"
android:textSize="40dp"/>
</LinearLayout>
</ScrollView>
</RelativeLayout>
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout

<ScrollView

android:layout_height="0dp"
android:layout_weight="1">
<LinearLayout

<TextView

android:layout_height="wrap_content"
android:text="Hallo Welt"
/>
</LinearLayout>
</ScrollView>
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_weight="0">
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Go next page"
android:layout_alignParentRight="true" />
</RelativeLayout>
</LinearLayout>
This worked for me. Give the scroll view a weight of 1. Put all the other widgets following the scroll view in a layout. The scroll view will grow enough to not block the rest.
Widgets in scroll view and rest at bottom
scrollview cannot fit the screen because you put it on a linear layout, so linear layout fit in the screen,
just try to make scrollview as root elemen on xml layout
<?xml version="1.0" encoding="utf-8"?>
<ScrollView
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/scrollView1"
android:layout_width="match_parent"
android:layout_height="wrap_content" >
<LinearLayout
android:id="#+id/linearLayout1"
android:layout_width="match_parent"
android:layout_height="wrap_content" >
<!-- Here you can put some XML stuff and BOOM! your screen fit to scrollview -->
</LinearLayout>
</ScrollView>
If you do not want to use RelativeLayout, it is better to use LinearLayout. This method is better in my opinion.
Just set the layout_weight to one
