How to add Layout on top of background image in Android

How to add Layout on top of background image in Android - android

I want to add Linear Layout on top of my background image as shown in below image(that horizontal bars).
But that is not working.I have checked by adding background color but it didn't shown in the preview.
Below is the way that I had added the Linear Layout.
<LinearLayout 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"
tools:context=".MainActivity"
android:background="#drawable/back">
<ImageView
android:layout_width="200dp"
android:layout_height="150dp"
android:src="#drawable/logo_big"
android:layout_marginLeft="200dp"/>
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"/>
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"/>
</LinearLayout>
</LinearLayout>

Try using a <RelativeLayout> around your <LinearLayout>.
Like this:
<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"
tools:context=".MainActivity"
android:background="#drawable/back">
<ImageView
android:layout_width="200dp"
android:layout_height="150dp"
android:src="#drawable/logo_big"
android:layout_marginLeft="200dp"/>
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"/>
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"/>
</LinearLayout>

Solution 1:
Set orientation = vertical in your parent LinearLayout.
Solution 2:
Use RelativeLayout for better UI experience.

Relative Layout inside Card View is not filling the parent even after giving match_parent

I have a cardView layout as below. I have used Stetho to inspect layout in chrome. I could see that Linear Layout is filling the screen width. However, relative Layout is not filling the parent.
<?xml version="1.0" encoding="utf-8"?>
<android.support.v7.widget.CardView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/card_view_show_card"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_margin="4dp"
android:clickable="true"
android:elevation="100dp"
android:focusable="true"
android:foreground="?android:attr/selectableItemBackground">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<RelativeLayout
android:id="#+id/image_layout_show_card"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<FrameLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
<ImageView
android:id="#+id/image_view_show_card"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:scaleType="fitXY" />
<View
android:layout_width="match_parent"
android:layout_height="match_parent" />
</FrameLayout>
</RelativeLayout>
</LinearLayout>
</android.support.v7.widget.CardView>

Relative layout fills the parent. Try applying different for the layouts to prove it. Something like this...
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#3367bb"
android:orientation="vertical">
<RelativeLayout
android:id="#+id/image_layout_show_card"
android:layout_width="match_parent"
android:background="#000000"
android:layout_height="wrap_content">
<FrameLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
<ImageView
android:id="#+id/image_view_show_card"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:scaleType="fitXY" />
<View
android:layout_width="match_parent"
android:layout_height="match_parent" />
</FrameLayout>
</RelativeLayout>
</LinearLayout>
</android.support.v7.widget.CardView>
You will see that the complete layout becomes black, that means it covers the parent.
If you remove background color of relative layout, you will get to see blue color of linear layout.
If the issue is something else, please ask a new question

The solution is to add this inside of your CardView:
app:cardPreventCornerOverlap="false"

LinearLayout child pushes other views

My activity's main layout is a LinearLayout. It has two children as an example. A RelativeLayout and a Button. The width and height of RelativeLayout are set to match_parent and the Button, match_parent and wrap_content. Unfortunately, RelativeLayout pushes the button below until it is not visible.
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
<ImageView
android:layout_width="match_parent"
android:layout_height="match_parent" />
</RelativeLayout>
<Button
android:layout_width="match_parent"
android:layout_height="wrap_content" />
</LinearLayout>
Why is this happening? I tried a tweak for the RelativeLayout which is changing the height to 0dp and weight to 1. It does make the Button visible but I am not sure if this is advisable as I only changed the height and weight of RelativeLayout.

Try this
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:fillViewport="true"
android:layout_height="match_parent">
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
<ImageView
android:layout_width="match_parent"
android:layout_height="match_parent" />
</RelativeLayout>
<Button
android:layout_width="match_parent"
android:layout_height="wrap_content" />
</LinearLayout>
</ScrollView>
OR
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:fillViewport="true"
android:layout_height="match_parent">
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<RelativeLayout
android:layout_width="match_parent"
android:layout_above="#+id/btn"
android:layout_height="match_parent">
<ImageView
android:layout_width="match_parent"
android:src="#drawable/disha"
android:layout_height="match_parent" />
</RelativeLayout>
<Button
android:id="#+id/btn"
android:layout_width="match_parent"
android:layout_margin="10dp"
android:text="NIlu"
android:layout_alignParentBottom="true"
android:layout_height="wrap_content" />
</RelativeLayout>
</ScrollView>

LinearLayout is either Vertical or Horizontal. Your first child which is RelativeLayout is matchParent then it will cover whole Outer layout .
Solution can be multiple its depends upon where exactly you want to place your Button . One way is .
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
>
<RelativeLayout
android:layout_width="match_parent"
android:layout_above="#+id/btn"
android:layout_height="match_parent">
<ImageView
android:layout_width="match_parent"
android:layout_height="match_parent" />
</RelativeLayout>
<Button
android:id="#+id/btn"
android:layout_width="match_parent"
android:layout_margin="10dp"
android:layout_alignParentBottom="true"
android:layout_height="wrap_content" />
</RelativeLayout>

Change your Code Like
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<RelativeLayout
android:layout_weight="1"
android:layout_width="match_parent"
android:layout_height="match_parent"
>
<ImageView
android:layout_width="match_parent"
android:layout_height="match_parent" />
</RelativeLayout>
<Button
android:text="#string/app_name"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
</LinearLayout>
Worked Foe me..
you should Give android:layout_weight="1" to relative Layout

//try this
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<ImageView
android:layout_width="match_parent"
android:layout_height="200dp" />
</RelativeLayout>
<Button
android:layout_width="match_parent"
android:layout_height="wrap_content" />
</LinearLayout>

this seems to work just fine.
I tried a tweak for the RelativeLayout which is changing the height to
0dp and weight to 1
the code look like this:
<?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">
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1"
>
<ImageView
android:layout_width="match_parent"
android:layout_height="match_parent"
/>
</RelativeLayout>
<Button
android:layout_width="match_parent"
android:layout_height="wrap_content"
/>
</LinearLayout>

In your layout, RelativeLayout is the first child of your LinearLayout. Since, you have set the height and width to match_parent it takes up all available space pushing the button out of the view.
When you set the RelativeLayout height to 0dp and weight to 1, LinearLayout first lays out all children based on the dimensions specified, and then distributes the remaining space based on the weight. In this case, the relative layout is 0dp, so it takes no space in first pass, and the button takes up space based on its onMeasure (lets say 100dp). The remaining space is now given to RelativeLayout because its weight is set to 1. Refer to the LinearLayout documentation for more details here.
You should consider using a RelativeLayout/ConstraintLayout as your root element.

Android Studio. XML layout width gets crushed in this relativelayout.

How can I align two views side-by-side in RelativeLayout? (Not Linearlayout)
I want to have ViewPager at 50dp width aligned at the right of the screen,
and have pink RelativeLayout take up the rest of the space.
I wish to avoid using 'weight' in Layouts.
Any solution, please?
<?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="120dp">
<RelativeLayout
android:id="#+id/dashboard_platform_view"
android:layout_width="match_parent"
android:background="#color/colorAccent"
android:layout_height="match_parent"
android:layout_alignParentTop="true"
android:orientation="vertical">
</RelativeLayout>
<android.support.v4.view.ViewPager
android:id="#+id/dashboard_platform_viewpager"
android:layout_toRightOf="#id/dashboard_platform_view"
android:layout_width="50dp"
android:layout_height="match_parent"
android:layout_alignParentRight="true"
android:layout_alignParentEnd="true"
android:background="#color/colorPrimary"
android:minWidth="50dp">
</android.support.v4.view.ViewPager>
</RelativeLayout>

I've checked it. So, here you go:
<?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="120dp">
<RelativeLayout
android:id="#+id/dashboard_platform_view"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_alignParentTop="true"
android:layout_toStartOf="#id/dashboard_platform_viewpager"
android:background="#color/colorAccent"
android:orientation="vertical"/>
<android.support.v4.view.ViewPager
android:id="#+id/dashboard_platform_viewpager"
android:layout_width="50dp"
android:layout_height="match_parent"
android:layout_alignParentEnd="true"
android:background="#color/colorPrimary"
android:minWidth="50dp"/>
</RelativeLayout>

Change your layout as bellow, may help to resolve your issue
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="120dp">
<android.support.v4.view.ViewPager
android:id="#+id/dashboard_platform_viewpager"
android:layout_width="50dp"
android:layout_height="match_parent"
android:layout_alignParentEnd="true"
android:layout_alignParentRight="true"
android:background="#color/colorPrimary"
android:minWidth="50dp" />
<RelativeLayout
android:id="#+id/dashboard_platform_view"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_alignParentTop="true"
android:layout_toLeftOf="#id/dashboard_platform_viewpager"
android:layout_toStartOf="#id/dashboard_platform_viewpager"
android:background="#color/colorAccent"
android:orientation="vertical" />
</RelativeLayout>

Try to add android:layout_toLeftOf="#+id/dashboard_platform_viewpager" for RelativeLayout, and remove toRightOf for ViewPager

Android layout_above does not work on API 21

I have a RelativeLayout that contains 3 children (LinearLayout) :
one at the top.
one at the bottom.
and one between the 2 last views.
The code i use for it is :
<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:background="#color/white"
tools:context="fr.caudoux.onlinegames.activities.GameMainFragment">
<LinearLayout
android:orientation="vertical"
android:background="#ff44f0c3"
android:layout_alignParentTop="true"
android:id="#+id/game_main_actionbar"
android:layout_width="match_parent"
android:layout_height="50dp">
</LinearLayout>
<LinearLayout
android:background="#F01234"
android:orientation="vertical"
android:id="#+id/game_main_top_container"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_below="#id/game_main_actionbar"
android:layout_above="#+id/game_main_chat_container">
</LinearLayout>
<LinearLayout
android:background="#ff2c3ff0"
android:layout_alignParentBottom="true"
android:orientation="vertical"
android:id="#id/game_main_chat_container"
android:layout_marginBottom="70dp"
android:layout_width="match_parent"
android:layout_height="50dp">
</LinearLayout>
</RelativeLayout>
Since the api 21 the attribut 'android:layout_above' is not working : the second LinearLayout take all the space below the first one, and the third LinearLayout is over the second.
On api lower than 21 it works : the second part take only the space between the first and the third Linearlayout.
Does anyone known why it is not working and hos to do ?
Thanks

Change the ordering to have your top and bottom view declared before the view that is in between the two:
<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:background="#color/white"
tools:context="fr.caudoux.onlinegames.activities.GameMainFragment">
<LinearLayout
android:orientation="vertical"
android:background="#ff44f0c3"
android:layout_alignParentTop="true"
android:id="#+id/game_main_actionbar"
android:layout_width="match_parent"
android:layout_height="50dp">
</LinearLayout>
<LinearLayout
android:background="#ff2c3ff0"
android:layout_alignParentBottom="true"
android:orientation="vertical"
android:id="#id/game_main_chat_container"
android:layout_marginBottom="70dp"
android:layout_width="match_parent"
android:layout_height="50dp">
</LinearLayout>
<LinearLayout
android:background="#F01234"
android:orientation="vertical"
android:id="#+id/game_main_top_container"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_below="#id/game_main_actionbar"
android:layout_above="#+id/game_main_chat_container">
</LinearLayout>
</RelativeLayout>
As mentioned, this same layout is easier to do as a LinearLayout, which specializes in stacked elements:
<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="#color/white"
android:orientation="vertical"
tools:context="fr.caudoux.onlinegames.activities.GameMainFragment">
<LinearLayout
android:orientation="vertical"
android:background="#ff44f0c3"
android:id="#+id/game_main_actionbar"
android:layout_width="match_parent"
android:layout_height="50dp">
</LinearLayout>
<LinearLayout
android:background="#F01234"
android:orientation="vertical"
android:id="#+id/game_main_top_container"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1">
</LinearLayout>
<LinearLayout
android:background="#ff2c3ff0"
android:orientation="vertical"
android:id="#id/game_main_chat_container"
android:layout_marginBottom="70dp"
android:layout_width="match_parent"
android:layout_height="50dp">
</LinearLayout>
</LinearLayout>
Note how only the middle element (the element that needs to fill the remaining space) has a layout_weight on it. This ensures that all remaining space is allocated to that view while the other views are of fixed height.

You cannot have both above and below set in one view. Use below on second view and then below again on last view.

How to make a webview is -10dp width and height of the parent layout?

How to make a webview is -10dp width and height of the parent layout with a background image look like the following image:
Updated:
The blue box is the screen.
The black box is the outer layout(#+id/wrapper) and the red box is the webview(#+id/webview)
The green box is some other layout.
I have tried with the following code but have no success.
If the content in the webview is too long, the outer layout will stretch. I want a fixed size webview inside the layout but I don't know how to achieve this.
Ps. The background image of the black box is not full screen.
Would somebody give me some hints?
<?xml version="1.0" encoding="utf-8"?>

use

Use this code instead
it will look like As shown in image
xml Code:

android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_margin="10dp" />
</LinearLayout>

android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:padding="10dp"

<WebView
android:id="#+id/webview"
android:layout_width="match_parent"
android:layout_height="match_parent"
