I have a layout like this
<?xml version="1.0" encoding="utf-8"?>
<GridLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"

<Button
android:layout_width="180dp"

android:layout_row="0"
android:layout_column="0"></Button>
<Button
android:layout_width="180dp"
android:layout_height="300dp"
android:text="Button2"
android:layout_gravity="right"
android:layout_row="0"

android:layout_height="300dp"
android:text="Button6"
android:layout_gravity="right"
android:layout_row="2"
android:layout_column="1"></Button>
</GridLayout>
Normally I will fit everything into a Relative or Constraint layout. But this time I intentionally made it big so that Button5 and Button6 can't be seen. And what I want is to make the layout scrollable so that the user can scroll up to see the Button5 and Button6?
How can I do it? What layout is to be used? Is there a way to make other layouts scrollale?
You have to do this if you want to scroll your view

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"

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?

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.
I am trying to use GridView to show 4 pieces of content. In the code bellow this content is only an ImageView, but a textView will later be added.
I created a 2x2 GridView, and I expected the screen space to be divided equally by all 4 grid cells, but that is not happening. If set to fill_parent the cell takes the whole screen (like image bellow), if set to wrap_content the cells get pilled up near one of the corners. How can I get the cell to distribute equally using only the XML layout file?
<?xml version="1.0" encoding="utf-8"?>

I've removed layout_height, layout_width, layout_rowSpan and layout_columnSpan and used the weight with layout_gravity="fill" instead.
I'm trying to create a GridLayout with 2 columns which will be centered.
My avtual design is:
<GridLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:custom="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent"
custom:rowCount="4"
custom:columnCount="2"
android:orientation="horizontal">
<TimeTableKeeper.Tile
android:layout_width="75dp"
android:layout_height="75dp"
android:gravity="top|left"
android:background="#00FF00"
custom:color="green"
custom:layout_row="0"
custom:layout_column="0" />
<TimeTableKeeper.Tile
android:layout_width="75dp"
android:gravity="top|left"
android:layout_height="75dp"
android:background="#00FF00"
custom:color="blue"
custom:layout_row="0"
custom:layout_column="1" />
</GridLayout>
And it looks like:
And I would like to have this buttons in the center and perfectly with spacing between them.
Is it possible?
--EDIT:
I have also tried putting it into LinearLayout, without results:
<?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:gravity="center"
android:orientation="vertical">
<GridLayout xmlns:custom="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent"
custom:rowCount="4"
custom:columnCount="2"
android:orientation="horizontal"
android:gravity="center"
android:layout_gravity="center">
<TimeTableKeeper.Tile
android:layout_width="75dp"
android:layout_height="75dp"
android:background="#00FF00"
custom:color="green"
custom:layout_row="0"
custom:layout_column="0" />
<TimeTableKeeper.Tile
android:layout_width="75dp"
android:layout_height="75dp"
android:background="#00FF00"
custom:color="blue"
custom:layout_row="0"
custom:layout_column="1" />
</GridLayout>
</LinearLayout>
Make the grid wrap around its content horizontally with layout_width="wrap_content" and set it's layout_gravity to center:
<GridLayout
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_gravity="center"
// ......
>
From GridLayout documentation:
GridLayout's distribution of excess space is based on priority rather than weight.
(...)
To make a column stretch, make sure all of the components inside it define a gravity.
So apparently you need to set the layout_gravity to android:layout_gravity="top|center" (I have not tested this, but from the documentation it should be along these lines.)
You're almost there. I think this will do the job:
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:custom="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<GridLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
custom:rowCount="4"
custom:columnCount="2"
android:layout_gravity="center_horizontal"
android:orientation="horizontal">
<TimeTableKeeper.Tile
android:layout_width="75dp"
android:layout_height="75dp"
android:background="#00FF00"
custom:color="green"
custom:layout_row="0"
custom:layout_column="0" />
<TimeTableKeeper.Tile
android:layout_width="75dp"
android:layout_height="75dp"
android:background="#00FF00"
custom:color="blue"
custom:layout_row="0"
custom:layout_column="1" />
</GridLayout>
</FrameLayout>
The code in below solved my problem.
<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">
<GridLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:layout_centerHorizontal="true"
android:layout_margin="30dp"
android:columnCount="3"
android:rowCount="4"
android:useDefaultMargins="true">
<ImageButton
android:layout_width="wrap_content"
android:layout_height="wrap_content"/>
<ImageButton
android:layout_width="wrap_content"
android:layout_height="wrap_content"/>
</GridLayout>
</RelativeLayout>
if you are using a constraint layout use wrap content on the grid layout and create the items inside it. It will be centered to the screen
<GridLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
app:layout_constraintTop_toBottomOf="#id/item"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintEnd_toEndOf="parent"
android:columnCount="2"
android:useDefaultMargins="true"
/>
copy this example for calculator layout =)
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="center"
>
<!-- android:useDefaultMargins="true" (OPTIONAL) -->
<GridLayout
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_gravity="center"
android:useDefaultMargins="true"
>
<Button

android:layout_row="0"
android:layout_width="70dp"
android:layout_height="70dp"
