I've the following xml file:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<FrameLayout
android:id="#+id/topFragment"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="center">
<ImageView
android:id="#+id/imageViewTest"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/icon_00" />
<TextView
android:id="#+id/textViewTest"
android:layout_below="#+id/imageViewTest"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="This is a Test"/>
</RelativeLayout>
<FrameLayout
android:id="#+id/bottomFragment"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="bottom|center_horizontal" />
</LinearLayout>
The first FrameLayout contains a fragment, which contains some buttons.
The RelativeLayout contains for example an image (changig size) and a text.
The last FrameLayout contains also a fragment, which contains either some buttons or some text or an image.
My aim is, that:
- the first FrameLayout is on top (that works)
- the elements in the RelativeLayout are centered in the middle of the screen (doesn't work)
- the last FrameLayout is on the bottom (doesn't work)
It should look like this:
My previous attempts with android:gravity="center" in the RelativeLayout and android:layout_gravity="bottom|center_horizontal" for the second FrameLayout failed.
Change the LineareLayout to Relative and use layout_centerInParent for the middle layout and alignParentBottom for the last one.
The top View will be anchored to the top by default
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"> //removed orientation as it won't be needed anymore
<FrameLayout
android:id="#+id/topFragment"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
<RelativeLayout
android:layout_width="wrap_content" // change here
android:layout_height="wrap_content"
android:layout_centernInParent="true"> // here
<ImageView
android:id="#+id/imageViewTest"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/icon_00" />
<TextView
android:id="#+id/textViewTest"
android:layout_below="#+id/imageViewTest"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="This is a Test"/>
</RelativeLayout>
<FrameLayout
android:id="#+id/bottomFragment"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true" /> //here
</RelativeLayout>
Use relative layout and use android:layout_centerHorizontal="true" instead of gravity.

I have no idea how to fix it -.-
The ListView's height is MATCH_PARENT which constrains it to the height of its parent ViewGroup. You should always define the height of scrollable views like ListView as WRAP_CONTENT so that it can freely expand according to the number of children.
Also it might be a good idea for the parent LinearLayout to be anchored to the top of the RelativeLayout:
android:layout_alignParentTop="true".
Leaving views floating freely in RelativeLayouts may have surprising consequences.
So I have a ScrollView which has a TextView inside. When the String for the text is longer than the screen width, It simply shifting in the next line. I want to avoid the new lining by adding HorizontalScrolling in ScrollView. Also, I want to make the text selectable so the user can copy the text. Is it possible?
<ScrollView
android:id="#+id/scroll_view"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fillViewport="true">
<TextView
android:id="#+id/text_view"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginStart="15dp"
android:layout_marginEnd="15dp"
android:layout_marginBottom="15dp"
android:ellipsize="end"
android:textIsSelectable="true"
android:justificationMode="inter_word"
android:lineSpacingExtra="5dp"
android:textSize="15sp"
tools:targetApi="o" />
</ScrollView>
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent" android:layout_height="match_parent"
android:scrollbars="vertical">
<HorizontalScrollView
android:layout_width="match_parent" android:layout_height="wrap_content">
<FrameLayout android:layout_width="320dp"
android:layout_height="match_parent"
android:background="#000000"/>
</HorizontalScrollView>
</ScrollView>
Try this:
<HorizontalScrollView
android:layout_width="match_parent"
android:layout_height="match_parent">
<TextView
android:layout_width="80dp"
android:layout_height="wrap_content"
android:scrollHorizontally="true"
android:text="Horizontal scroll text view"/>
</HorizontalScrollView>
I created linearlayout with two buttons in center (buttons 1 and 2), but I can't manage it to create the view 3 on top, which I need to make it fill whole width and adjust it's height by it (keep proportions). How do I create third view?
Image:
Code:
<?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:background="#drawable/bg"
android:layout_gravity="center_horizontal"
android:orientation="horizontal">
<LinearLayout
android:orientation="vertical"
android:layout_gravity="center_vertical"
android:layout_width="fill_parent" android:layout_height="wrap_content" >
<ImageButton
android:background="#drawable/btn_one"
android:layout_width="wrap_content" android:layout_height="wrap_content"
android:layout_gravity="center_horizontal"
android:layout_weight="1.0" />
<ImageButton
android:background="#drawable/btn_second"
android:layout_width="wrap_content" android:layout_height="wrap_content"
android:layout_gravity="center_horizontal"
android:layout_weight="1.0" />
</LinearLayout>
I would recommend you use relative layouts, they are the closest thing in android to an "absolute layout" replace the button tags with Image button tags
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent">
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:layout_centerHorizontal="true">
</RelativeLayout>
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="New Button"
android:id="#+id/button2"
android:layout_alignParentTop="true"
android:layout_centerHorizontal="true"
android:layout_marginTop="215dp" />
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="New Button"
android:id="#+id/button3"
android:layout_below="#+id/button2"
android:layout_alignStart="#+id/button2" />
</RelativeLayout>
try this code set height and width what size of image button you need and simple look what you need.
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent">

android:layout_height="match_parent"
android:layout_weight="1">
<ImageButton
android:layout_width="match_parent"
android:layout_height="match_parent"/>
</LinearLayout>
<LinearLayout
android:layout_width="match_parent"

<ImageButton

android:layout_height="50dp"/>
<ImageButton
android:layout_width="200dp"
android:layout_height="50dp" />
</LinearLayout>
I've got a few linear layouts stacked on top of each other, the centre one has an imageview. I'm trying to get a textview on top of the imageview in the centre however I'm having trouble. I've tried with relative layout however it messes up all my other layouts. Any simple solutions to this?

I'm trying to get the text view on top of the id/picPreview image view
LinearLayout is designed to place layouts/views in a row (linearly).
One solution would be something like this:
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_weight="6"
android:orientation="vertical" >
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
<ImageView
android:id="#+id/picPreview"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#000000"
android:contentDescription="#string/imageDesc"
android:layout_centerInParent="true"
android:src="#null" />
<TextView
android:id="#+id/picPreviewLbl"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_centerInParent="true"
android:text="Overlay" />
</RelativeLayout>
</LinearLayout>
Why not just use a TextView in place of the centered ImageView and then set the background of the text be the solid color that you are currently using? Eg.
<TextView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#000000"
android:text="Sample Text" ... />
Please have a look at the following code
<ScrollView 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"
tools:context=".DisplayResult" >
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal"
>
<ImageView
android:id="#+id/zodiac1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/aries"
/>
<TextView
android:id="#+id/orTxt"
android:text="Or"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
/>
<ImageView
android:id="#+id/zodiac2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/gemini"
/>
</LinearLayout>
</ScrollView>
I need to center everything inside the LinearLayout. I must use scrollview because when the app is 100% done, there will be lot of information which cannot be viewed by a single glance, without scrolling. How can make these center? Please help!
UPDATE
use any layout inside the scroll, no prob. But I need those elements to be in the same order (one after another) and centered.
you need to set gravity as centered for linear layout
< LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:gravity="center"
android:orientation="horizontal" >
This one worked for me:
<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:gravity="center">
<ScrollView
android:layout_width="match_parent"
android:layout_height="wrap_content"
>
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
android:gravity="center"
Try using layout_gravity on your LinearLayout to center_horizontal:
<LinearLayout
android:layout_width="wrap_content"
android:layout_gravity="center_horizontal"
android:layout_height="wrap_content"
android:orientation="horizontal"/>
<ScrollView 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"
tools:context=".DisplayResult"
scrollbars="horizontal">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal"
android:gravity="center_horizontal">
<ImageView
android:id="#+id/zodiac1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/aries"
/>
<TextView
android:id="#+id/orTxt"
android:text="Or"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
/>
<ImageView
android:id="#+id/zodiac2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/gemini"
/>
</LinearLayout>
</ScrollView>
#If you want to Linear layout in a center you need to write android:gravity="center_horizontal" in your linear layout.
