Android linearLayout children not expanding to fill parent - java

I have the following as a layout of mine:
<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=".MyActivity">
<EditText
android:id="#+id/text1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_weight="1"
android:background="#drawable/bubble_b"
android:textAppearance="?android:attr/textAppearanceMedium" />
<RatingBar
android:id="#+id/rating"
style="?android:attr/ratingBarStyle"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal"
android:numStars="5"
android:rating="4"
android:stepSize="0.5"
android:layout_weight="1"/>
This makes my edittext and ratingbar be pushed up to the top and both of the heights are just 'wrap_content'. I have tried with RelativeLayouts as well and all that happens is the EditText takes up the entire screen and pushes the ratingbar off the screen.
Why are the layout weights not working as expected? If edittext weight is 3 and the ratingbar is 1 I would assume the edittext would take 75% of the screen, and so forth?
The background is a 9patch image so it should have no problem expanding either.
Thank you


I believe you want something 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"
android:weightSum="1">
<EditText
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="EditText"
android:ems="10"
android:id="#+id/editText"
android:layout_weight="0.53" />
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_weight="0.53">
<RatingBar
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:id="#+id/ratingBar"/>
</RelativeLayout>
</LinearLayout>


use Relative Layout to center object:
<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=".MyActivity">
<RelativeLayout
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_weight="1">
<EditText
android:id="#+id/text1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#drawable/bubble_b"
android:textAppearance="?android:attr/textAppearanceMedium"
android:layout_centerInParent="true" />
</RelativeLayout>
<RelativeLayout
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_weight="1">
<RatingBar
android:id="#+id/rating"
style="?android:attr/ratingBarStyle"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal"
android:numStars="5"
android:rating="4"
android:stepSize="0.5"
android:layout_weight="1"/>
</RelativeLayout>


Change LinearLayout's
android:layout_height="wrap_content"
to
android:layout_height="match_parent".
Also, instead of setting "0dp" to EditText and RatingBar set it to match_parent.
[Update]
<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=".MyActivity">
<EditText
android:id="#+id/text1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_weight="1"
android:textAppearance="?android:attr/textAppearanceMedium" />
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="center"
android:layout_weight="1">
<RatingBar
android:id="#+id/rating"
style="?android:attr/ratingBarStyle"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:numStars="5"
android:rating="4"
android:stepSize="1" />
</LinearLayout>
</LinearLayout>

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.

ScrollView top part is cut off when I added adjustPan so keyboard won't overlap EditText

I have a ScrollView (with a RecyclerView inside) and a RelativeLayout after it which contains EditText. I added
android:windowSoftInputMode="stateAlwaysHidden|adjustPan"
for the activity in my manifest file because my keyboard overlaps the EditText but in effect, whenever the keyboard is active, the top part of my ScrollView is cut off.
I have tried using NestedScrollView and setting RelativeLayout android:layout_height="wrap_content" and android:layout_gravity="center" but that doesn't work. Below is the snippet of my code:
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"

android:layout_alignParentTop="true"

In your adapter's xml , RelativeLayout tag ,write wrap_content replace of match_parent like below;
android:layout_height="wrap_content"

Change your single_listview_item.XML's RelativeLayout from android:layout_height="match_parent" to android:layout_height="wrap_content"
Change your ListView's height to wrap_content too

Android layout_weight not working as it should be

I'm trying to set my ImageView and LinearLayout to have half of the screen each. This works fine on tablets, but on smaller screens the image takes up the entire screen (thus, not actually working).
The way I see it is, I have set a layout_weight="1" on both the ImageView and LinearLayout and the layout_width="0dp" on both also. This SHOULD work, as I have researched a lot into this.
My Code:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout

android:layout_width="match_parent"

Thanks, appreciate any help!

I would say your problem is with your LinearLayout's height being set to match_parent inside of a ScrollView.
As you know, a ScrollView expands to fit its contents - now if you tell its contents to expand as big as its parent (match_parent), then you have a paradox.
Try setting the child of your ScrollView's height to wrap_content instead of match_parent.

There is no use for your ScrollView & it's parent RelativeLayout. Cut down your layout as below.
<LinearLayout>
<ImageView w="1"/>
<ScrollView w="1">

Overlaying textview with imageview linear layout

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" ... />
