I have an activity which contains mainly 2 components: A Scroll view and a Button.
I want to place the button at the buttom of the screen, fixed.
I tried many things but i cannot keep the button location fixed at the button of the screen, bacause as the content of the scroll view increases, the button is pushed outside the activity screen.
I want to achieve something like this:
Can anyone tell me how to achieve this?
My XML file is clean (all custom views are programmatically written, can't be shared!):
<ScrollView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="#+id/scrollView"
android:layout_gravity="center_horizontal">
<LinearLayout
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:id="#+id/editableViewGroup"></LinearLayout>
</ScrollView>
<Button
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="Save Changes"
android:id="#+id/customButton" />
Use a LinearLayout:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<ScrollView
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1"
android:fillViewport="true">
<!-- ... -->
</ScrollView>
<Button
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="Save Changes"/>
</LinearLayout>
Use a RelativeLayout to host your views and pin the Button to the bottom of the layout.
you can use LinearLayout or relativeLayout like this
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<ScrollView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="#+id/scrollView"
android:layout_gravity="center_horizontal">
<LinearLayout
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:id="#+id/editableViewGroup"></LinearLayout>
</ScrollView>
<Button
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="Save Changes"
android:id="#+id/customButton" />
</LinearLayout>
If you use a relative layout try 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"
android:paddingBottom="#dimen/activity_vertical_margin"
android:paddingLeft="#dimen/activity_horizontal_margin"
android:paddingRight="#dimen/activity_horizontal_margin"
android:paddingTop="#dimen/activity_vertical_margin"
tools:context="com.example.testproject.MainActivity" >
<ScrollView
android:id="#+id/scrollView1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_alignParentStart="true"
android:layout_alignParentTop="true"
android:layout_above="#+id/button1">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical" >
</LinearLayout>
</ScrollView>
<Button
android:id="#+id/button1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_centerHorizontal="true"
android:text="Button" />
</RelativeLayout>

The following should show a scrollview that takes up the entire screen except for a small portion large enough for a button at the bottom. When I run this the button/layout does not show up at all. Only the scrollview which takes up the entire screen with other views I have within the scrollview. Thoughts?
<LinearLayout android:layout_width="match_parent"
android:layout_height="match_parent"
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
tools:context="com.th3ramr0d.armybodyfatcalculator.MainActivity"
android:orientation="vertical">
<ScrollView
android:layout_width="match_parent"
android:layout_height="wrap_content">
</ScrollView>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Button 1"
/>
</LinearLayout>
</LinearLayout
This will do the job for you
<RelativeLayout android:layout_width="match_parent"
android:layout_height="match_parent"
xmlns:android="http://schemas.android.com/apk/res/android"
tools:context="com.th3ramr0d.armybodyfatcalculator.MainActivity"
xmlns:tools="http://schemas.android.com/tools"

<ScrollView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_alignParentTop="true"
android:layout_above="#+id/myButton">
</ScrollView>
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Button 1"
android:layout_alignParentBottom="true"
android:id="#+id/myButton" />
</RelativeLayout>
I have a Button in Linear Layout when I see in the Design view of Activity xml ,it looks like it is perfectly positioned but when I see in GenyMotoin avd it is farly placed from what I expected.
How to dynamically adjust the position of button on different screen sizes?
My 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"
android:layout_width="match_parent"
android:layout_height="match_parent"

android:paddingLeft="#dimen/activity_horizontal_margin"
android:paddingRight="#dimen/activity_horizontal_margin"
android:paddingTop="#dimen/activity_vertical_margin"

android:layout_marginTop="100dp"
android:layout_marginLeft="20dp" />
</LinearLayout>
</RelativeLayout>
Use Linear Layout for the outermost layout.
It's not clear what your trying to achieve but If you want to position your views at the center on all devices. Try to use RelativeLayout instead of LinearLayout:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout 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"
android:background="#b6b6b6"
android:padding="#dimen/activity_vertical_margin"
android:weightSum="2"
android:orientation="vertical"
tools:context="com.offtogeek.motivatemyself.MainScreen">
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_weight="1"
android:orientation="horizontal">
<TextView
android:id="#+id/textView"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_centerInParent="true"
android:gravity="left"
android:textSize="50dp" />
</RelativeLayout>
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_weight="1"
android:orientation="horizontal">
<Button
android:id="#+id/button"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:layout_weight="1"
android:text="Next Quote" />
</RelativeLayout>
</LinearLayout>
I'm trying to design something like that :
Currently i'm having issue putting the button at "the middle" of the two layouts reunion point. Is there a way i do this ?
Thanks.
Here is a way to do it
<?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"
android:layout_weight="1">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:weightSum="1">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_weight="0.5"
android:background="#FF0000">
<!-- TO ADD CONTENT HERE -->
</LinearLayout>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_weight="0.5"
android:background="#FFFF00"
android:weightSum="0.5">
<!-- TO ADD CONTENT HERE -->
</LinearLayout>
</LinearLayout>
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:background="#000000"
android:text="TEST"
android:textColor="#FFFFFF"/>
</RelativeLayout>
OUTPUT:
You can change the layout height from android:layout_weight="0.5"
you can use RelativeLayout for your parent and try adding twoLinearLayouts , one below another and set their heights, now place a Button in your RelativeLayout and set android:layout_centerInParent="true" for your Button .
and if you want to use weight for layouts, instead of adding two LinearLayout to your RelativeLayout, add one LinearLayout with weightSum=100 and then add two LinearLayouts to it with custom weights.
for your case , you have to do sth like this :
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:weightSum="100" >
<LinearLayout
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="20"
android:background="#f00" >
</LinearLayout>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="80"
android:background="#0f0" >
</LinearLayout>
</LinearLayout>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:weightSum="100" >
<LinearLayout
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="20" >
</LinearLayout>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="center" >
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:gravity="center_horizontal"
android:text="test" />
</LinearLayout>
</LinearLayout>
</RelativeLayout>
I'm relatively new to Android development and I'm having a hard time putting together a certain interface. I've looked through many similar questions but none of them give me the answer i'm looking for.
I want to put together an XML interface like the following:
I want a LinearLayout that acts like a sticky footer that will contain two Buttons. This part will always align to the bottom and and will always be 60dp high. The RelativeLayout would then be on top of the footer, but it's height should scale depending on the screen size.
I've tried the following:
<LinearLayout 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"
android:orientation="vertical"
tools:context=".DartboardActivity">
<RelativeLayout
android:id="#+id/game_layout"
android:layout_width="match_parent"
android:layout_height="506dp"
android:background="#drawable/background"
android:paddingBottom="#dimen/activity_vertical_margin"
android:paddingLeft="#dimen/activity_horizontal_margin"
android:paddingRight="#dimen/activity_horizontal_margin"
android:paddingTop="#dimen/activity_vertical_margin">
<ImageView
android:id="#+id/Dartboard"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:contentDescription="#string/desc_dartboard"
android:src="#drawable/dartboard" />
<hhs.week3.dartboard.VerticalSeekBar
android:id="#+id/seekBarVertical"
android:layout_width="wrap_content"
android:layout_height="fill_parent"
android:layout_gravity="bottom"
android:thumb="#drawable/thumbhorizontal"
android:layout_marginBottom="40dp" />
<SeekBar
android:id="#+id/seekBarHorizontal"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:thumb="#drawable/thumbhorizontal" />
</RelativeLayout>
<LinearLayout
android:id="#+id/buttons"
android:layout_width="match_parent"
android:layout_height="60dp"
android:background="#333">
<Button
android:id="#+id/fire"
style="#style/button"
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_margin="5dp"
android:text="#string/fire" />
<Button
android:id="#+id/settings"
style="#style/button"
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_margin="5dp"
android:text="#string/settings" />
</LinearLayout>
</LinearLayout>
I got it working half decently, but it requires me to give the RelativeLayout bit a fixed height, making it look right on my phone, but not on others.
How do I best approach this?
Use the LinearLayout layout_weight mechanism to assign all remaining space to your RelativeLayout:
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="0px"
android:layout_weight="1"
... />
<LinearLayout
android:layout_width="match_parent"
android:layout_height="60dp"
... />
</LinearLayout>
Try following code
<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"
android:orientation="vertical"
tools:context=".DartboardActivity" >
<RelativeLayout
android:id="#+id/game_layout"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_above="#+id/buttons"
android:layout_alignParentTop="true"
android:background="#drawable/ic_launcher"
android:paddingBottom="#dimen/activity_vertical_margin"
android:paddingLeft="#dimen/activity_horizontal_margin"
android:paddingRight="#dimen/activity_horizontal_margin"
android:paddingTop="#dimen/activity_vertical_margin" >
</RelativeLayout>
<LinearLayout
android:id="#+id/buttons"
android:layout_width="match_parent"
android:layout_height="60dp"
android:layout_alignParentBottom="true"
android:background="#333"
android:orientation="vertical" >
</LinearLayout>
</RelativeLayout>
I removed LinearLayout and replaced with RelativeLayout. This will allow you to set your LinearLayout stick to bottom.
I was able to achieve the same result by using below code. Basically, the parent layout is one Linear layout and the first child element is a scrollview so it can squeeze its content when the keyboard is shown. Also note the use of the android:layout_height="0dp" and android:layout_weight="1" used with the scrollview
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/wrap"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<ScrollView
android:id="#+id/wrap2"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1" >
<LinearLayout
android:id="#+id/LinearLayout1"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="horizontal" >
</LinearLayout>
</ScrollView>
<FrameLayout
android:id="#+id/buttonsPanel"
android:layout_width="match_parent"
android:layout_height="40dp"
android:background="#333" >
<TextView
android:id="#+id/textView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="action buttons" />
</FrameLayout>
</LinearLayout>
Try this
<LinearLayout 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"

I want to put a ListView at the top of my activity, and something else on the bottom without the ListView "swallowing" the widgets on the bottom? I tried this (with the "something else" being a RelativeLayout with a single button in it), but it doesn't work.
<LinearLayout 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"
android:orientation="vertical" >
<ListView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="bottom" >
</ListView>
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="fill_parent"
android:layout_gravity="bottom" >
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_alignParentLeft="true"
android:text="Button" />
</RelativeLayout>
</LinearLayout>
I looked for some hints here, which is very useful, but doesn't say anything about ListViews. I can place widgets above a ListView without problem, but not below.
Use a RelativeLayout as the root layout then position the ListView with layout_above and the Button with layout_alignParentBottom:
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent" >
<ListView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_above="#+id/button" >
<Button
android:id="#+id/button"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_alignParentLeft="true"
android:text="Button" />
</RelativeLayout>
I'm sure this is already answered several times on SO...
Change your layout like this:
<LinearLayout 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"
android:orientation="vertical" >
<ListView
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1"
android:layout_gravity="bottom" >
</ListView>
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="bottom" >
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_alignParentLeft="true"
android:text="Button" />
</RelativeLayout>
</LinearLayout>
