Android cannot re-size LinearLayout

Android cannot re-size LinearLayout - android

I've been working on an android application recently, and in the last day or so I've been working on the GUI using the eclipse layout editor. Unfortunately, I can't resize my linearlayout in any way other than the x-dimension. I can also resize it by resizing the TextView contained within it. As sushil stated, I can't control the height of my linearlayout. My 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:orientation="vertical" >
<ScrollView
android:id="#+id/scrollView"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_weight="1" >
<LinearLayout
android:id="#+id/helpLinearLayout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_gravity="top"
android:orientation="horizontal" >
<TextView
android:id="#+id/InfoTitle"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Info:"
android:textSize="35sp" />
</LinearLayout>
</ScrollView>
</LinearLayout>

Try this. Add android:fillViewport="true" to the ScrollView
<ScrollView
android:id="#+id/scrollView"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fillViewport="true">

I don`t know if I understood what you want, but try to change this:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
to this:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
this way, it will fill the screen when size is different.

How to Set a Button at a fixed position even when respective Activity has ScrollView

Is there a way to use some non scrollable view when the activity has ScrollView component?
I want that my button behaves similar to the button in the question below, I want it fixed on the bottom of the UI too:
how to set a button at a fixed location on the bottom of UI?
Here's my layout code:
<?xml version="1.0" encoding="utf-8"?>
<ScrollView
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<LinearLayout

<LinearLayout

android:orientation="vertical"
android:paddingTop="20dp">
</LinearLayout>
</LinearLayout>
</ScrollView>
Thanks in advance!

The link you have attached in your question shows how you can do it. You can use RelativeLayout for this. The idea is, you need to tell a button to stay on bottom of the screen & tell the scrollview to stay above the Button along with it's scrollable content like:
<?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">
<Button
android:id="#+id/btnMy"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"/>
<ScrollView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_above="#+id/btnMy">
<LinearLayout
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"
android:layout_above="#id/btnMy"
android:orientation="vertical">
<FrameLayout
android:id="#+id/map_frameview"
android:layout_width="match_parent"
android:layout_height="200dp">
</FrameLayout>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
android:paddingTop="20dp">
</LinearLayout>
</LinearLayout>
</ScrollView>
</RelativeLayout>

Problems placing view on top of SlidingPaneLayout

I want to place a view via include on top of a SlidingPaneLayout. In the layout preview of Androíd Studio it is displayed correctly but on my device the view won't show - why?
Here is the complete layout file:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<include layout="#layout/online_state"
android:layout_height="5dp"
android:layout_width="wrap_content"/>
<android.support.v4.widget.SlidingPaneLayout
android:id="#+id/content_view_spl"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="?attr/color_background_primary"
android:orientation="vertical" >
<de.timroes.android.listview.EnhancedListView
android:id="#+id/list"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:background="?attr/color_background_primary"
android:divider="#color/black"
android:dividerHeight="1dp" />
</LinearLayout>
<LinearLayout
android:id="#+id/selected_item"
android:layout_width="fill_parent"
android:layout_height="match_parent"
android:layout_weight="1"
android:orientation="vertical" >
</LinearLayout>
</android.support.v4.widget.SlidingPaneLayout>

Ok, got it...
I have to place the SlidingPaneLayout below the view...
Stupid question... sorry ;)

how to have 2 relative layouts divided by half in activity?

i want to divide my screen in half vertically, and do a different color in each half,
i was trying to use this solution mentioned in here>
Android: 2 relative layout divided in half screen
but it doesn't work for me.
this is my layout:
<?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"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:baselineAligned="false"
android:orientation="horizontal"
app:layout_behavior="#string/appbar_scrolling_view_behavior"
tools:context=".activities.alignmentActivities.Add_New_Project_Activity"
tools:showIn="#layout/app_bar_add__new__project_">
<RelativeLayout
android:layout_width="0dp"
android:layout_height="wrap_content"
android:background="#f00000"
android:layout_weight="1">
</RelativeLayout>
<RelativeLayout
android:layout_width="0dp"
android:background="#00b0f0"
android:layout_height="wrap_content"
android:layout_weight="1">
</RelativeLayout>
</LinearLayout>
how can i achieve the desired effect of 2 layouts each takes half the screen vertical \ what am i doing wrong then the example mentioned in the link ?

You may Try to use 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:weightSum="2"
android:orientation="horizontal"
app:layout_behavior="#string/appbar_scrolling_view_behavior">
<RelativeLayout
android:layout_width="0dp"
android:layout_height="match_parent"
android:background="#f00000"
android:layout_weight="1">
</RelativeLayout>
<RelativeLayout
android:layout_width="0dp"
android:background="#00b0f0"
android:layout_height="match_parent"
android:layout_weight="1">
</RelativeLayout>
Output :

Add the following attribute in your LinearLayout
android:weightSum="2"
After adding this your code will work.
WeightSum attribute defines the total number of equal divisions you want it to be divided.If you want it to be divided into 3 parts, change its value as 3.

<?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="horizontal">
<RelativeLayout
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_weight="1"
android:background="#color/red">
</RelativeLayout>
<RelativeLayout
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_weight="1"
android:background="#color/white">
</RelativeLayout>
</LinearLayout>

If you want to divide screen vertically than you need to use android:orientation="vertical" and in child layout use android:layout_width="match_parent"
check below xml,
<?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:baselineAligned="false"
android:orientation="vertical"
android:weightSum="2"
app:layout_behavior="#string/appbar_scrolling_view_behavior" >
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1"
android:background="#f00000" >
</RelativeLayout >
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1"
android:background="#00b0f0" >
</RelativeLayout >
</LinearLayout >

Scrolling issue - Android Scrollview

I seem to be having an issue getting my app to scroll fully. I think there is an issue with the linear layout but would like your help to solve this:
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<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="com.app.aks.fragments.ThreeFragment">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
android:padding="8dp">
//// some image and text views //////
</LinearLayout>
</LinearLayout>
</ScrollView>
The window only scrolls partially and not all the way to the bottom....Suggestions?

In your MainActivity.java
Or whereever you are using/initializing these views.
Try this for all the textviews/image views. which are nested inside.
view.setMovementMethod(new ScrollingMovementMethod());

The direct child of ScrollView should be another layout that supports multiple children, such as RelativeLayout or LinearLayout.
<?xml version="1.0" encoding="utf-8"?>
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<LinearLayout
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<ImageButton ... />
<TextView ... />
<TextView ... />
<TextView ... />
</ScrollView>

Try with setting android:fillViewport="true" on the ScrollView:
<ScrollView
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:fillViewport="true">

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"?>
<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="#drawable/common_background" >
... some other layout ...
<LinearLayout
android:id="#+id/wrapper"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:background="#drawable/wrapper_background" >
<WebView
android:id="#+id/webview"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_margin="10dp" />
</LinearLayout>
... some other layout ...
</RelativeLayout>

use
android:padding="10dip" to the parent of webview.

Use this code instead
it will look like As shown in image
xml 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:background="#drawable/ic_launcher" >
... some other layout ...
<LinearLayout
android:id="#+id/wrapper"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_centerInParent="true"
android:background="#drawable/ic_launcher" >
<WebView
android:id="#+id/webview"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_margin="10dp" />
</LinearLayout>
... some other layout ...
</RelativeLayout>

Not tested but you can try this:
<LinearLayout
android:id="#+id/wrapper"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:padding="10dp"
android:background="#drawable/wrapper_background" >

Try out this:
<?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:background="#drawable/common_background" >
... some other layout ...
<LinearLayout
android:id="#+id/wrapper"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_centerInParent="true"
android:padding="10dip" <---- Apply this in your layout.
android:background="#drawable/wrapper_background" >
<WebView
android:id="#+id/webview"
android:layout_width="match_parent"
android:layout_height="match_parent"
/>
</LinearLayout>
... some other layout ...
</RelativeLayout>

Use this code instead
<LinearLayout
android:id="#+id/wrapper"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_above="#+id/someOtherLayout"
android:layout_centerInParent="true"
android:background="#drawable/wrapper_background" >
<WebView
android:id="#+id/webview"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_margin="10dp" />
</LinearLayout>
<Some Other Layout
android:id="#+id/someOtherLayout"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true" />
