Unable to fix 4 buttons in Grid Layout - android

I tried to add 4 buttons in Grid Layout. Equally Spaced, I used colum and row Weight, but still I am not able to align all equally spaced, I am getting the output like this. Mentioned below in the image.
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

I am using MinSdk version 19.


Copy the below xml as it is and run it you would see same equally space button.
Note: You have to run it on your device to see them filling all screen space equally
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:layout_width="match_parent"
android:layout_height="match_parent"

android:paddingRight="#dimen/activity_horizontal_margin"
android:paddingTop="#dimen/activity_vertical_margin">
<GridLayout
android:layout_width="match_parent"
android:layout_height="match_parent"

You can use two LinearLayouts instead, one for each row, and also replace the parent RelativeLayout with another LinearLayout.
<?xml version="1.0" encoding="utf-8"?>

android:layout_height="match_parent"
android:orientation="vertical"
android:weightSum="2">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1"
android:weightSum="2"
android:orientation="horizontal">
<Button
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_weight="1"/>
<Button
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_weight="1"/>
</LinearLayout>

You are facing this error because of your property
( android:layout_gravity = "fill" )
actually this is used to fill the container
check out this link
http://developer.android.com/reference/android/widget/LinearLayout.LayoutParams.html


Your code snippet working fine.You might be facing issues due to some other layout parameters changes in your project.
I will recommend try to create new project and check your layout again

Buttons going outside of the screen - Android

I need help...
I was trying to build 3 buttons aligned in 1 row and 3 columns inside of a GridLayout, and looks its working, but I think I haven't done that right, because if change the size of the text inside the button (textSize) the GridLayout and the buttons are going outside of the screen.
I think that I'm setting the layout_witdh and/or layout_height wrong, but I'm not sure.
Can anyone help me? Thanks :)

change the following in each button
android:layout_width="0dip"
android:layout_weight ="1"
you can do this in LinearLayout itself, no need of grid layout

Use this
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"

<Button
android:id="#+id/id0"
android:layout_width="0dp"

I couldn't figure the issue in that case but i just used the regular grid layout with column and row indication for each button. That did the trick.
Notice that I have layout_column and layout_row to specify where they should stand.

Cannot display two buttons with one button as twice the width of other in GridLayout

I need to use GridLayout to display two buttons. One and second one with twice the width of other button. I want the NEXT button be twice the width of BACK button and I need a GridLayout.
My source code is as below:
<?xml version="1.0" encoding="utf-8"?>
<GridLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
style="#style/Calculator.Grid"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:columnCount="3"
app:rowCount="1">
<Button
android:id="#+id/button_back"
android:layout_column="0"
android:layout_columnSpan="1"
android:layout_columnWeight="1"
android:layout_gravity="left|top"
android:background="#drawable/bg_back_button"
android:text="#string/back"
android:textColor="?attr/colorTextSecondary"
android:textSize="16sp" />
<Button
android:id="#+id/button_next"
android:layout_column="1"
android:layout_columnSpan="2"
android:layout_columnWeight="2"
android:layout_gravity="fill"
android:background="#drawable/bg_next_button"
android:text="#string/next"
android:textColor="?attr/colorTextPrimary"
android:textSize="16sp" />
</GridLayout>
Desired display (NEXT Button should be double the width of BACK button) :
But the result is (Problem) :

If you don't have any problem with Linear Layout as inner container then use this
<?xml version="1.0" encoding="utf-8"?>

GridLayout columns do not appear right

I tried to configure a grid layout with 2 rows and 2 columns. But each element here occupies the entire width of the screen, while the second column is outside the screen. Please suggest what am I doing wrong here.

Try this:
for Uniform width column and row in Gridlayout use:
android:layout_columnWeight="1"
android:layout_rowWeight="1"
use this layout:

Issues trying to create GridLayout with elements of different size

I'm trying to create a static grid-like layout in Android so I'm using GridLayout instead of GridView.
This is the layout I'm trying to achieve
Using the code from here as a base. I'm also a little confused about specifying layout_{weight, margin} on every element inside the grid, since it's my understanding that the rowSpan and colSpan parameters should take care of that. Is this not incorrect?
Any pointers?
<?xml version="1.0" encoding="utf-8"?>
<GridLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/GridLayout1"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:columnCount="2"
android:rowCount="2"
tools:context=".MainActivity" >
<android.support.v7.widget.CardView
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:id="#+id/card_view"
android:layout_column="0"
android:layout_gravity="fill"
android:layout_row="0"
android:layout_columnSpan="1">
<Button
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:id="#+id/button3"
android:text="Button" />

You were so close, try this instead:
<GridLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/GridLayout1"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:columnCount="2"
android:rowCount="2"
tools:context=".MainActivity" >
<android.support.v7.widget.CardView
android:id="#+id/card_view"
android:layout_column="0"
android:layout_gravity="fill_horizontal"
android:layout_row="0"
android:layout_columnSpan="2">
<Button
android:layout_height="match_parent"
android:layout_width="match_parent"
android:id="#+id/button3"
android:text="Button" />
</android.support.v7.widget.CardView>
<android.support.v7.widget.CardView
android:id="#+id/card_view1"
android:layout_column="0"
android:layout_row="1"
android:layout_columnSpan="1"
android:layout_columnWeight="1">
<Button
android:layout_height="match_parent"
android:layout_width="match_parent"
android:id="#+id/button1"
android:text="Button" />
</android.support.v7.widget.CardView>
<android.support.v7.widget.CardView
android:id="#+id/card_view3"
android:layout_column="1"
android:layout_row="1"
android:layout_columnWeight="1">
<Button
android:layout_height="match_parent"
android:layout_width="match_parent"
android:id="#+id/button2"
android:text="Button" />
</android.support.v7.widget.CardView>
</GridLayout>
You need to use layout_gravity="fill_horizontal" for the first item, to stretch the whole row. And play with layout_columnWeight for the 2nd and 3rd item.
