fixed width LinearLayout

I'm trying to get two linear layout side by side and put content inside of it.
I want the two linear layouts to be side by side, but the left one should take about 3/4 of the screen and the right one the rest of it.
This is my code: https://gitlab.com/snippets/1682040
But the two linear layouts always change the width and the height depending on the content.
How can I have two linear layouts side by side with fixed width and height?
A better solution with RelativeLayout is always welcome.
This is the result:

Use layout_weight property of LinearLayout and android:weightSum property for parent layout.
Do Something like this
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="horizontal"
android:padding="15dp"
android:weightSum="1">
<LinearLayout
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_weight=".75" // For First layout to 3/4
android:background="#color/colorPrimary"
android:gravity="left|center"
android:orientation="vertical">
//First Layout content Here
</LinearLayout>
<LinearLayout
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_weight=".25" // For Second layout to rest of screen
android:background="#color/colorAccent"
android:gravity="center"
android:orientation="vertical">
//Second Layout Content Here
</LinearLayout>
</LinearLayout>

I know that you asked for a solution with the LinearLayout but I suggest you to solve this problem with the ConstraintLayout. You will get incredible performance improvements without nested view.
In this sample I added a vertical guideline at 75% of from the left of the screen. I have only to remove the nested LinearLayouts and add the constraints to your views!
Try it out!

Try this give Your first LinearLayout android:layout_weight=".75" so it can take 3/4 space in screen
than assign android:layout_weight="0.25" to Your second LinearLayout so it can take remaining space

Seems like both of the weights are set to "1". Have you tried ".5"?

First remove weightSum attribute from parent layout.
If you want your first layout to be 3/4 of you should put weight 0.75 and 0.25 (1/4) for the other one like here:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="horizontal"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:padding="15dp">

android:layout_weight=".75"
android:layout_gravity="left"
android:gravity="left|center">
<TextView
android:id="#+id/repository_name"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="AAAAA"
android:textColor="#color/blue"
android:textSize="20dp"/>
<TextView
android:id="#+id/repository_description"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:maxLines="2"
android:ellipsize="end"
android:text="AAAAA"
android:textColor="#color/gray"
android:textSize="15dp"/>
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="horizontal"
android:gravity="center">
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/ic_menu_camera"/>
<TextView
android:id="#+id/repository_fork_number"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="123"
android:textColor="#color/orange"
android:textSize="20dp"/>

android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/ic_menu_camera"
android:layout_marginLeft="15dp"/>
<TextView
android:id="#+id/repository_star_number"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="123"
android:textColor="#color/orange"
android:textSize="20dp"/>
</LinearLayout>
</LinearLayout>
<LinearLayout
android:layout_width="0dp"
android:layout_height="match_parent"
android:orientation="vertical"
android:background="#color/colorAccent"
android:layout_weight=".25"
android:gravity="center">

<TextView
android:id="#+id/first_last_name"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Mock Name"
android:textColor="#color/lightGray"/>
</LinearLayout>

try this:
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal">
<LinearLayout
android:layout_width="0dp"
android:layout_height="match_parent"

<TextView

android:layout_height="wrap_content"
android:background="#drawable/shape_txt"

</LinearLayout>
</LinearLayout>

Change the weight sum to 4 in the parent layout and add weight as 3 for child linear layout so it can take 3/4 space and 1 to child linear layout so that it will take the remaining space.

how to align tableview column to the largest value text value in adjecent column

I apologise if this is a duplicate question but I cant seem to find anything relevant on here.
My problem is that I have a TableView:
Is it possible to align the second column to that of the longest string value in the first one?

if i get your question clearly , then you need to increase the size of the ExitText view so that you can write large string.
you need to change the android:layout_weight="1" to android:layout_weight="2" . The number actually represent the percentage(weight) of the View. like :
<EditText
android:id="#+id/edit_quantity"
android:layout_width="0dp"
android:layout_weight="2"
android:layout_height="wrap_content"
android:hint="Number of units"
android:inputType="number"
android:textAppearance="?android:textAppearanceSmall" />

As you can see from my layout, the outer LinearLayout contains 3 RelativeLayout which all have layout_weight equals to 1 and the LinearLayout has weightSum equal to 3.
However, the behavior of the current layout is: The 1st RelativeLayout shared very little space (around 10%) and the 2nd & 3rd RelativeLayout shared 45% of height.
How can I make them equally shared the height?

Add to below attributes to ScrollView
android:layout_centerVertical="true"
android:fadingEdge="none"
android:fillViewport="true"

Because your using scrollview you need to fill your view port to make the scroll view occupy the whole screen
<ScrollView
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fillViewport="true"/>
//..... your other code here
</ScrollView>

ScrollView Not Working(It's Not Scrolling the layout)

I am new to Android and working on a App and stuck here on ScrollView. I have tried width and height "match parent" but still not working. I am posting my code. I have wasted more than an hour on this. Thanks in advance.
Here is my XML:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

</LinearLayout>

set lay out weight to scroll view like
<ScrollView
android:layout_weight="0.96"
android:layout_width="match_parent"
android:layout_height="wrap_content">

Make the control in LinearLayout not to fill all the space

I have a layout like this:
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal"
android:layout_weight="1" >
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="fsfsdfds"
android:layout_gravity="center_vertical" />
<EditText
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_vertical" />
</LinearLayout>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal"
android:layout_weight="1" >
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="fdsfdsfds"
android:layout_gravity="center_vertical" />
<EditText
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_vertical" />
</LinearLayout>
<Button
android:layout_width="match_parent"
android:layout_height="wrap_content" />
It fill the whole space of the activity.
How can I make these 2 TextViews and EditTexts take only space enough to show themselves (not fill all the space) and align the button to the bottom?

I think this is what you're looking for :
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<LinearLayout
android:id="#+id/LinearLayout1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_vertical"
android:text="TextView1" />
<EditText
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_gravity="center_vertical"
android:layout_weight="1"
android:inputType="text" />
</LinearLayout>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_below="#id/LinearLayout1"
android:orientation="horizontal">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_vertical"
android:text="TextView2" />
<EditText
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_gravity="center_vertical"
android:layout_weight="1"
android:inputType="text" />
</LinearLayout>
<Button
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:text="Button" />
</RelativeLayout>
EDIT :
If you don't want to use the two LinerLayouts (and therefore gain even more performance), you can do the following :
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<TextView
android:id="#+id/TextView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignBaseline="#id/EditText1"
android:layout_gravity="center_vertical"
android:text="TextView1" />
<EditText
android:id="#+id/EditText1"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_alignParentEnd="true"
android:layout_alignParentRight="true"
android:layout_gravity="center_vertical"
android:layout_toEndOf="#id/TextView1"
android:layout_toRightOf="#id/TextView1"
android:inputType="text" />
<TextView
android:id="#+id/TextView2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignBaseline="#id/EditText2"
android:layout_below="#id/TextView1"
android:layout_gravity="center_vertical"
android:text="TextView2" />
<EditText
android:id="#+id/EditText2"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_alignParentEnd="true"
android:layout_alignParentRight="true"
android:layout_below="#id/EditText1"
android:layout_gravity="center_vertical"
android:layout_toEndOf="#id/TextView2"
android:layout_toRightOf="#id/TextView2"
android:inputType="text" />
<Button
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:text="Button" />
</RelativeLayout>

Check This.
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal"
android:weightSum="1">
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="center_vertical"
android:layout_weight="0.5"
android:text="fsfsdfds" />
<EditText
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="center_vertical"
android:layout_weight="0.5" />
</LinearLayout>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal"
android:weightSum="1">
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="center_vertical"
android:layout_weight="0.5"
android:text="fdsfdsfds" />
<EditText
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="center_vertical"
android:layout_weight="0.5" />
</LinearLayout>
<Button
android:layout_width="match_parent"
android:layout_height="wrap_content" />

You try with RelativeLayout, or else if wanted to be done with LinearLayout you need to consider weights if width is not fillparent.
Check below sample to start with ..
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_vertical"
android:layout_weight="0.2"
android:text="fsfsdfds" />
<EditText
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_vertical"
android:layout_weight="0.8" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_vertical"
android:layout_weight="0.2"
android:text="fdsfdsfds" />
<EditText
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_vertical"
android:layout_weight="0.8" />

Either convert to a relative-layout and use alignparentbottom for the button - or use layout weights for the linear-layouts
