Which stretchMode to use in GridView on android - android

Following is my xml code:
<?xml version="1.0" encoding="utf-8"?>
<GridView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/gridviewgallery"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:columnWidth="#dimen/gridview_column_width"
android:numColumns="auto_fit"
android:verticalSpacing="0dp"
android:horizontalSpacing="0dp"
android:stretchMode="columnWidth"
android:gravity="center"
android:background="#444444"
/>
When I use android:stretchMode="columnWidth" , it creates a gap between the columns(though it fills the screen width)
And if I use android:stretchMode="none" , it gets left aligned and there is a gap left on right side of screen(though now there is no gap between columns)
Problem is I want both : To fill the screen width as well no gap between columns.
How to achieve it?

A combination of android:numColumns="auto_fit" android:stretchMode="columnWidth" and android:columnWidth="60dp" will give you a layout that adjusts for different screen sizes. Much better than fixing the number of columns. See example below...
<GridView
android:id="#+id/tablegrid"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#ffff7965"
android:horizontalSpacing="5dp"
android:verticalSpacing="5dp"
android:layout_marginStart="5dp"
android:layout_marginLeft="5dp"
android:numColumns="auto_fit"
android:stretchMode="columnWidth"
android:gravity="center"
android:columnWidth="60dp"
/>

It's very simple dude, just remove the line
android:columnWidth="#dimen/gridview_column_width"
you can specify any number of columns, i am given number of column = 4
android:numColumns = "4"
This is working fine for me

I know this question is a little old but here is an answer I found hoping this helps someone else, just for android:stretchMode use spacingWidthUniform as it says in documentation here it will stretch the spacing between columns equally.
please refer to above link for more information.

Your answer would be appreciated.
Give marginLeft to your GridView.
Try using this.
<GridView
android:id="#+id/gridView"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:horizontalSpacing="10dp"
android:numColumns="auto_fit"
android:verticalSpacing="10dp"/>

How to cenralize last uneven row in GridView in android?

I have a GridView , which displays pictures of alphabets
what happens is , every time in the last row there are less no of alphabets.
and the last row is left aligned , which doesn't look good
so I want make the last row to be in centre,
any suggestion
My GridView code:
<?xml version="1.0" encoding="utf-8"?>
<GridView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/grid_view"
android:layout_width="fill_parent"
android:layout_marginRight="20dp"
android:layout_marginTop="20dp"
android:layout_height="fill_parent"
android:numColumns="auto_fit"
android:columnWidth="70dp"
android:horizontalSpacing="10dp"
android:verticalSpacing="20dp"
android:gravity="center"
android:stretchMode="spacingWidthUniform" >
</GridView>
I have the same problem, but I managed this using two gridviews, with first gridview displaying the rows except the last row, with the second gridview displaying the last row. This is the simplest way to achieve what I need.
I have not find a better solution. Looking forward to see a nice and simple way also.
you could try using invisible elements, it not the most efficient solution but is simple, you can put two elements, one at the start, one at the end of the row and make them invisible
For those who are still looking for a solution for this here's my take for this, create a TableLayout and, and for each TableRow set its weigth to android:weightSum="4" and dont forget to add android:gravity="center"
For complete code check this gist for reference.
You could center the grid row inside of a relative layout and then add android:layout_centerHorizontal="true" to the alphabet ImageView's. Assuming that they're ImageView's.
So your GridView would be wrapped in something like this:
<RelativeLayout
android:layout_width="wrap_content"
android:layout_height="wrap_cotent"
android:orientation="horizontal" >
<GridView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/grid_view"
android:layout_width="fill_parent"
android:layout_marginRight="20dp"
android:layout_marginTop="20dp"
android:layout_height="fill_parent"
android:numColumns="auto_fit"
android:columnWidth="70dp"
android:horizontalSpacing="10dp"
android:verticalSpacing="20dp"
android:gravity="center"
android:stretchMode="spacingWidthUniform" >
</GridView>
</RelativeLayout>
And the individual alphabet images would need android:layout_centerHorizontal="true" like this:
<ImageView
android:layout_width="50dp"
android:layout_height="50dp"
android:layout_centerHorizontal="true"
</ImageView>

Adjust GridView (Android)

I have a problem with grid view layout on Android. I can't find solution to eliminate extra space in grid view.I mention the code fro gridview as below :-
<?xml version="1.0" encoding="utf-8"?>
<GridView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/gridview"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:alwaysDrawnWithCache="true"
android:background="#android:color/background_dark"
android:clipChildren="true"
android:columnWidth="100dp"
android:gravity="center_horizontal"
android:horizontalSpacing="2dp"
android:numColumns="auto_fit"
android:padding="0dp"
android:scrollingCache="true"
android:smoothScrollbar="true"
android:stretchMode="columnWidth"
android:verticalSpacing="2dp" />
now my application's grid view look like this
As shown there is extra space which i want to remove it and it can look like this:-
So please provide me solution..
Thanks in advance..
You need to alter the value for android:columnWidth attribute for all layout types [hdpi,mdpi,xhdpi etc.] supported by your application.
You can use :
android:listSelector="#null"
to eliminate extera space
and try this , for 3 column cell:
android:numColumn = "3"

Set GridView in center horizontal

I have an application in which I am using a GridView to show some image of different number. I want to set the GridView in the center of screen horizontally that is to be run perfect on every phone of different sizes or density pixels.
Thanks in advance.
code
<GridView
android:id="#+id/gridview"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:gravity="center"
android:horizontalSpacing="5dp"
android:numColumns="3"
android:stretchMode="columnWidth"
android:verticalSpacing="5dp" >
</GridView>
your 'GridView' must be in some parent layout for example Linearlayout.Set following two properties of that parent layout
android:layout_gravity="center"
android:gravity="center"
Note:You must use both attributes at the same

Android silly ui problem

I'm new on Android and I have a silly problem with my application design.
My problem is that I want to make a grid as shown in this example http://developer.android.com/guide/tutorials/views/hello-gridview.html
but I want to create a texbox below the grid and a button after the grid. The textbox has to be always at the top and the button always at the bottom. I have done this:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent" android:orientation="vertical">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/textView1"
android:layout_marginLeft="20px"
android:text="#string/intro"
android:layout_marginTop="20px"
android:textSize="35px">
</TextView>
<GridView
android:id="#+id/gridView1"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
android:numColumns="auto_fit"
android:verticalSpacing="10dp"
android:horizontalSpacing="10dp"
android:columnWidth="90dp"
android:stretchMode="columnWidth"
android:gravity="center"
</GridView>
<Button
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="#string/Button_create"
android:textSize="18px">
android:id="#+id/button1">
</Button>
</LinearLayout>
But with this code I have the textbox at the top but not the button at the bottom always. It appears when the grid finish. Also I noticed that in the example there're 2 o 3 columns inside the grid as I want but with this code it only appears one and I do not know why.
Could you help me?
PS. For who will edit the code zone, could you explain me what I have to put when a line ends but it continues the code? Thanks and sorry for your time editing my post
You should put an android:layout_gravity value of e.g. 1 to the GridView which you have determined to fill the height of the parent and then for the Button, put value of 0.5.
