I have following code for Gridview (To make the Calendar).
<GridView
android:id="#+id/calendar"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_above="#+id/rl1"
android:layout_below="#+id/ll2"
android:columnWidth="250dp"
android:numColumns="7" >
</GridView>
Grid_Cell is as follows.
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#drawable/calendar_button_selector" >
<Button
android:id="#+id/calendar_day_gridcell"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#drawable/calendar_button_selector"
android:gravity="center"
android:textAppearance="?android:attr/textAppearanceSmall"
android:textColor="#000"
android:textSize="14.47sp" >
</Button>
<TextView
android:id="#+id/num_events_per_day"
style="#style/calendar_event_style"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:gravity="center" >
</TextView>
I want to set no space between the rows and columns.
Existing view is as following.
Please help me out... Thanks in Advance
.
I will try to give you a snippet, but to be honest, there is no point of using a GridView for your case since all you items are there on the screen anyway. You can create a couple of LinearLayouts in a small loop that will get the result.
I would advice you to set the columnWidth on Runtime according to the screen width.
And your adapter should be fed with the column width and height to set them when inflating child views. And in this case, you need to get rid of numColumns. Remember that using numColumns along with columnWidth makes no sense especially when you want to fill the whole space. If you want to set the numColumns, remove the columnWidth.
SOLUTION:
Here is the outcome:
First, we create our layout. In my case, it is the MainActivity's layout and is called activity_main.xml. (Notice there is no GridView because I'll add that later in code):
<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"
tools:context=".MainActivity" >
<TextView
android:id="#+id/header"
android:background="#444"
android:gravity="center"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:textAppearance="?android:attr/textAppearanceLarge"
android:textColor="#android:color/white"
android:text="Dynamic Static GridView" />
<TextView
android:id="#+id/footer"
android:gravity="center"
android:background="#444"
android:textColor="#android:color/white"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_centerHorizontal="true"
android:layout_centerVertical="true"
android:textAppearance="?android:attr/textAppearanceLarge"
android:text="Shush" />
</RelativeLayout>
Our GridView element's layout is here in the item_grid.xml:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:background="#fff"
android:layout_height="match_parent" >
<TextView
android:id="#+id/text"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:textAppearance="?android:attr/textAppearanceLarge" />
</RelativeLayout>
Now the trick is in MainActivity (I have commented some of the code for you to understand):
package com.example.dynamicstaticgridview;
import android.os.Bundle;
import android.os.Handler;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ArrayAdapter;
import android.widget.GridView;
import android.widget.RelativeLayout;
import android.app.Activity;
import android.graphics.Color;
/**

public class MainActivity extends Activity {
private static String items[]; //these are temporary items :p do not use them
static {
items = new String[7*7];
for(int i=0;i<7*7;i++) {
items[i] = String.valueOf(i);
}
}
int numberOfColumns = 7; //defaulting to 7, you can change it when you know
int numberOfRows = 7; //defaulting to 7, you can change it when you know
GridView mGrid;
ArrayAdapter<String> mAdapter;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
RelativeLayout.LayoutParams params = new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.MATCH_PARENT, RelativeLayout.LayoutParams.MATCH_PARENT);
params.addRule(RelativeLayout.BELOW, R.id.header);
params.addRule(RelativeLayout.ABOVE, R.id.footer);
mGrid = new GridView(this) {
#Override
protected void onLayout(boolean changed, int l, int t, int r, int b) {
super.onLayout(changed, l, t, r, b);
if(!calculated)
getDimens();
}
};
mGrid.setVerticalSpacing(0);
mGrid.setHorizontalSpacing(0);
mGrid.setStretchMode(GridView.NO_STRETCH);
mGrid.setBackgroundColor(Color.rgb(100, 10, 10));
((RelativeLayout)findViewById(R.id.rootview)).addView(mGrid, params);
}
private int mCellWidth;
private int mCellHeight;
boolean calculated = false;
protected void getDimens() {
calculated = true;
//here you might have some rounding errors
//thats why you see some padding around the GridView
mCellWidth = mGrid.getWidth()/numberOfColumns;
mCellHeight = mGrid.getHeight()/numberOfRows;
mGrid.setColumnWidth(mCellWidth);
mGrid.setNumColumns(numberOfColumns);
mAdapter = new ArrayAdapter<String>(this, R.layout.item_grid, R.id.text, items) {
#Override
public View getView(int position, View convertView, ViewGroup parent) {
GridView.LayoutParams params = null;
if(convertView == null) {
params = new GridView.LayoutParams(mCellWidth, mCellHeight);
}
convertView = super.getView(position, convertView, parent);
if(params != null) {
convertView.setLayoutParams(params);
}
return convertView;
}
};
mGrid.setAdapter(mAdapter);
}
}
COMMENTS:
You'd really better find a decent algorithm to choose mCellWidth, mCellHeight, numberOfColumns, and numberOfRows.
I might be wrong but as far as I know the GridView is an AdapterView, which in your case means that you can't dynamically, through xml, format the height of your items in a way so that they always fill the entire parent. That is not the way grid views (and list views and other adapter views) work.
These kind of "scrollable container views" could be seen as microfilm readers that used to exist in "modern libraries" a very long time ago. One needs to realize that the data has really nothing to do with the actual viewer, you just use your viewer (the GridView in your case) with a fix with and height to pan over the underlaying data items which also have their fix widths and heights.
As I see it you're trying to explicitly target the very corner-case where the data just happens to have the same geometric size as your viewer window.
A few tips, though:
You could instead have a look at GridLayout. The GridLayout is introduced in API level 14 (IceCream Sandwich) so you might have to rethink your version support strategy there (if I'm not completely misstaking it should also be included in the v7 support package for backwards compatibility on older platforms, in that case you could simply add the jar to your app to support older API levels).
Yet another tip would be to use a TableLayout with corresponding table rows and what not. The TableLayout has been around from day one, so there is no backward compataibility issues there, but they do tend to become very layout intensive, though. If you are planning to reload your view a lot or scroll between months smoothly, I'm not sure this is the solution for you (due to the amount of deep layout routes).
A third solution would be that you still use the GridView, but you measure the height of it and dynamically set a fix height to your inflated grid view items from your grid view adapter, based on the measured GridView height (In other words: you make sure you enter the above mentioned corner-case).
If you use the GridView you'd need to get rid of the vertical spacing as well. There is a android:stretchMode attribute on the GridView which you could play around with. You could also try different (negative?) dimensions on the android:verticalSpacing attribute.
Good luck with your custom calendar view!
If you want to give a height and width to your gridview put a relative layout outside of the gridview and give android:layout_width and android:layout_height to your relative layout. Then give your gridview's width and height to match_parent. After that if you want to give exact height and width to your gridview cell elements at first you have to know the exact width and height of all cells and you should define the columnWidth according to that, for example for this code
<GridView
android:id="#+id/calendar"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_above="#+id/rl1"
android:layout_below="#+id/ll2"
android:columnWidth="250dp"
android:numColumns="7" >
</GridView>
if you dont have 1000dp layout outside you never get 4 cells in one row in a good view but only gridview will try to determine its own cell width.
for your situation your calendar gridview should be something like this:
<GridView
android:id="#+id/calendar"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_above="#+id/rl1"
android:layout_below="#+id/ll2"
android:columnWidth="50dp"
android:numColumns="7" >
</GridView>
It seems to be a solution for you http://www.anddev.org/how_to_display_gridview_with_gridlines_and_borders-t11099.html
Try setting these two values in XML for your GridView:
android:horizontalSpacing="0dp"
android:verticalSpacing="0dp"
You'll probably want to remove the android:columnWidth field.

I have a problem with spacing in my Android app: Unwanted space between columns.
I noticed similar questions have been asked on stackoverflow before, but none seemed to match exactly my case.
Here's what it looks like (using the code below)... http://i.imgur.com/OXIms9n.png
From my PlayAdapter.java
#Override
public View getView(int index, View view, ViewGroup viewGroup) {
ImageView imageView = new ImageView(context1);
imageView.setImageBitmap(images[index]);
return imageView;
}
From my Spacing.java
GridView gridView = (GridView) findViewById(R.id.gridview2);
final PlayAdapter PlayAdapter1 = new PlayAdapter(this, images);
gridView.setAdapter(PlayAdapter1);
gridView.setNumColumns(numCols);
gridView.setColumnWidth(width);
(numCols and width are determined programmatically elsewhere )
The GridView:
<GridView xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/gridview2"
android:layout_marginLeft="2dp"
android:layout_marginRight="2dp"
android:horizontalSpacing="2dp"
android:verticalSpacing="2dp"
android:layout_gravity="center"
android:stretchMode="spacingWidthUniform">
</GridView>
So, if stretchMode is set to "columnWidth", "spacingWidth" or
"spacingWidthUniform" there is too much space between
the columns of the grid. See the imgur link above for the result.
Here's a solution I already tried instead:
If stretchMode is changed to "none", the grid is centered
vertically in portrait mode, but not horizontally in
landscape mode. Looks like this: http://i.imgur.com/Di6TgS2.png
Changing the settings for gravity and
layout_gravity did not help, nor did making a LinearLayout
around the gridview.
Any other ideas what to do?
I am all for reusing views in listview. I always set visibility, contents, witdth etc. of all controls again in getView Unfortunately it seems ListView fails to recalculate height.
Picture one shows the initial item showed:
Picture two shows how item one is rendered after we scrolled away and back into it
The background linearlayout height (the black area) made me think that in picture two, Android is reusing a view that just showed a much heigher item (e.g. the second item). But why does it not recalibrate/reset/recalclulate itself (it is in "wrap_content" mode in its XML) when reused as view for the first item which content (text + image) is not as heigh?
In truth I am not sure what is happening. The problem only manifests itself if I have image in the view. I have tried organize the bitmap/image loading in different ways (sample code underneath) with different things commented out, but that does not seem to make much difference. I am really at a loss here as to the reason.
override_listitem_news.xml
<?xml version="1.0" encoding="utf-8"?>

<ImageView

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

</LinearLayout>
Here is code where I load image in getView
ViewTreeObserver vto = image.getViewTreeObserver();
vto.addOnGlobalLayoutListener(
new OnGlobalLayoutListener() {
#Override
public void onGlobalLayout() {
image.getViewTreeObserver().removeGlobalOnLayoutListener(this);
image.setScaleType(ImageView.ScaleType.CENTER_INSIDE);
SharedCode.sharedUtilScaleImage_Width(image);
}
}
);
image.setTag(data.image_file_name + data.image_file_url);
Bitmap bit = null;
bit = SharedCode.sharedGetFileFromOffline(thisActivityContext, "news", data.image_file_name, MyGetKindOfFile.ImageAsBitmap).bitmap;
if (bit != null) {
image.setImageBitmap(bit);
image.setVisibility(View.VISIBLE);
}
else {
image.setImageBitmap(null);
image.setVisibility(View.GONE);
}
image.setPadding(0, 0, 0, 0);
image.setBackgroundColor(data.backgroundColorInt);
For what it is worth, problem appeared to be related to the imageview. Just for reference, I will write here how I solved it.
In getView I fixed the imageview width to screen width (instead of "wrap-content" and/or parent view width - earlier code used OnGlobalLayoutListener for parent width)
I switched over to using SetDrawable instead of SetImageBitmap. It is odd, but this difference was actual very important in solving the odd space around the imageview after scrolling an item/row in/out of view.
My research did also indicate that others had problems using wrap_content in listview for cases similar to mine, but I was not able to find anyone who had experienced exact same problems as me.
I have spent hours on this and looked at every related SO question I could find without a solution.
Here is my problem:
I have a gridview of images. I need 3 columns (to match the iOS version and aesthetics). If I set the numColumns to 3, I get a lot extra space between the top and bottom of the image row for each row. If I set the width to autofit, I always get 2, they look better but would prefer 3 columns.
What am I missing?

I am hoping it is something easy that I am just missing. Thanks in advance.
UPDATED: Added Screenshot. The problem is that only 1 row is showing, if you scroll down, you see the other 3 rows, but there is a huge space in between.
<edit>
Please find "Tip 3" below. Example with code can be found here.
</edit>
I think the problem is that you set the layout_height of your <GridView> to wrap_content. The grid view doesn't seem to be able to calculate it's total, wrapped height properly, hence, it's showing one row only.
You could either set the layout_height to match_parent (or any other, fixed height - like 120dp or whatever) or your could try to extend the GridView Java object and do some own calculation (you would then need to use your custom grid view object in your XML-layout as well: <com.package.to.MyCustomGridView>).
I do need to stress, though, that there aren't any well defined way of getting hold of the number of columns from the grid view in Java code prior to API 11 (you would want this in order to calculate how many rows your data adapter would produce). The getNumColumns was introduced in API 11. Neither is there a proper way of finding the spacing between rows (the getHorizontalSpacing() and getVerticalSpacing() methods were introduced in API 16).
For your reference: http://developer.android.com/reference/android/widget/GridView.html
Tip 1:
I haven't tested this my self, but you could try something like this:
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<ImageView
android:layout_width="match_parent"
android:layout_height="wrap_content"
...
/>
<GridView
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1.0"
...
/>
</LinearLayout>
I.e. including your grid view in the linear layout and adding all available space to it after the image view has been laid out.
Tip 2:
You could write your own list view. There seems to be some good candy on the Sony Mobile tutorial site (and no, I'm not employed by Sony Mobile :-), nevertheless; a good tutorial is a good tutorial): http://developer.sonymobile.com/2010/05/20/android-tutorial-making-your-own-3d-list-part-1/
Tip 3:
You could extend the Java GridView object and override the onMeasure method as below example. Remember to refer to your extending GridView class in the Android layout XML file (like <com.package.MyGridView android:layout_width="match_parent" android:layout_height="wrap_content" ... />)
#Override
protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
int heightSpec;
// The great Android "hackatlon" (in order to enable "wrap_content" on grid views).
if (getLayoutParams().height == LayoutParams.WRAP_CONTENT) {
heightSpec = MeasureSpec.makeMeasureSpec(
Integer.MAX_VALUE >> 2, MeasureSpec.AT_MOST);
}
else {
heightSpec = heightMeasureSpec;
}
super.onMeasure(widthMeasureSpec, heightSpec);
}
Hopefully you'll find some inspiration in this :-)

I have a layout with 3 fragments:
<LinearLayout android:id="#+id/acciones"
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="horizontal">
<LinearLayout
android:id="#+id/fragment1"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_weight="1">
</LinearLayout>
<LinearLayout
android:id="#+id/fragment2"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_weight="1">
</LinearLayout>
<LinearLayout
android:orientation="vertical"
android:id="#+id/f3"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_weight="1">
</LinearLayout>
</LinearLayout>
In the first fragment I have a TableLayout in which I have one custom TextView in each row.
I want to know the width of the fragment because if the custom TextView is wider than the fragment, I'll set the number of lines necessary.
This is what I've done in my custom TextView:
#Override
protected void onMeasure (int widthMeasureSpec, int heightMeasureSpec) {
super.onMeasure(widthMeasureSpec, heightMeasureSpec);
mMaxWidth = (float) (getMeasuredWidth());
}
With this line I got the width from the three Fragments, not only the one which contains the custom TextView.
Thanks.
You should be able to set the width of the TextView to be fill_parent, in which case it will do the wrapping for you. You should not set the widths of your layouts to be match_parent since it is inefficient when you're using layout weights.
Since android's layout system is occasionally mysterious with regards to view sizes, if setting the TextView width to be fill_parent actually makes it take up the whole screen (as your question appears to be implying) do the following:
Set your TextView width to 0 by default. In onCreate of your activity, after setting the content view:
findViewById(R.id.acciones).getViewTreeObserver().addOnGlobalLayoutListener(new OnGlobalLayoutListener() {
#Override
public void onGlobalLayout() {
final int fragmentWidth = findViewById(R.id.releventFragmentId).getWidth();
if (fragmentWidth != 0){
findViewById(R.id.yourTextViewId).getLayoutParams().width = fragmentWidth;
}
}
});
By setting the TextView's width to 0 initially, you prevent it from changing the widths of the fragments. Then you can use a view tree observer to get the width of whatever fragment you're interested in (by looking at its root view) after layout has occurred. Finally you can set your TextView to be that exact width, which in turn will do the wrapping for you automatically.
Note that onGlobalLayout can be called multiple times and is regularly called before all of the views have been completely laid out, hence the != 0 check. You will also probably want to do some kind of check to make sure that you only set the width of the text view once, or otherwise you can get into an infinite layout loop (not the end of the world, but not good for performance).
currently i have the following layout
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_alignParentRight="true"
android:layout_marginTop="9px"
android:layout_below="#+id/desc"
android:id="#+id/ll_item"
android:orientation="vertical"
android:paddingRight="3px"
android:paddingLeft="3px"
android:paddingBottom="5px"
android:paddingTop="5px"
android:background="#drawable/rounded_corner_lists" >
<!--
<ListView android:drawSelectorOnTop="false" android:id="#+id/lv" android:layout_height="fill_parent" android:layout_width="wrap_content" android:divider="#ddd" android:dividerHeight="1px" android:background="#drawable/white" />
-->
</LinearLayout>
the listview that i have commented out, i have tried to make this in the xml, with the height set to wrap_content, fill_parent, currently i am doing this programatically with the following code
LinearLayout ll_item = (LinearLayout) this.findViewById(R.id.ll_item);
if(list.length() > 0)
{
ll_item.setVisibility(View.VISIBLE);
LinearLayout.LayoutParams lp = new LinearLayout.LayoutParams(LayoutParams.WRAP_CONTENT,calcListHeight(list));
listview = new ListView(this);
listview.setBackgroundResource(R.drawable.white);
listview.setDivider( new ColorDrawable(this.getResources().getColor(R.drawable.dividercolor)) );
listview.setDividerHeight(1);
listview.setCacheColorHint(0);
mAdapter = new JSONAdapter( list, this );
listview.setAdapter(mAdapter);
mAdapter.notifyDataSetChanged();
ll_item.addView(listview, lp);
}
this is the result
so you can see in this image, that since i'm containing the listview in a linearlayout to get the rounded corner look, it doesn't just automatically stretch to contain the entire listview, is there any way to have the two elements just wrap the content vertically so there is no scrolling without me programatically setting the height ? ? ?
i guess one other thing i should mention is that i have all this layout in a scrollview, because i want this listview to be a tiny subsection of the entire layout, so it would be something like
-scrollview
-textview
-textview
-linearlayout
-listview
- button
here is a simpler layout of what i have
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout android:orientation="vertical" android:layout_height="fill_parent" android:layout_width="fill_parent"
android:background="#drawable/bg" xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/titlebar">
<ScrollView android:id="#+id/sv" android:layout_width="fill_parent" android:background="#drawable/bg"
android:layout_height="fill_parent" xmlns:android="http://schemas.android.com/apk/res/android">
<RelativeLayout android:id="#+id/widget28"
android:layout_width="fill_parent" android:layout_height="fill_parent" android:padding="4dip"
>
<LinearLayout android:orientation="vertical" style="#style/rounded_corner_full_width_button"
android:id="#+id/editfields">
<ListView android:drawSelectorOnTop="false" android:id="#+id/lv" android:layout_height="fill_parent"
android:layout_width="wrap_content" android:divider="#ddd" android:dividerHeight="1px"
android:background="#drawable/white"/>
</LinearLayout>
</RelativeLayout>
</ScrollView>
</LinearLayout>
ListViews do not go in ScrollViews.
ListView is for displaying a limited window into unbounded content efficiently. If you were to "disable scrolling" on a ListView to put it within a ScrollView you lose all practical reason for using a ListView in the first place.
If you want to use a ListView to show lots of content or unbounded content but also have content above and below that scrolls with it, add header or footer views to the ListView using addHeaderView or addFooterView. If the list content is going to be a small portion of your overall layout as you describe, this probably isn't the best approach for you.
If you have a small, bounded set of content to present, go ahead and use a ScrollView and programmatically generate child views for your "list items" where appropriate.
A common pattern used in the framework to mix inflated XML content with programmatically generated content is to add a placeholder view in the layout XML, usually a LinearLayout or FrameLayout. Use findViewById to locate it at runtime and add generated child views to it.
You could even still use a ListAdapter with this approach if you have one written already, just call content.addView(adapter.getView(position, null, content)) in a loop for all adapter positions (where content is the placeholder view you located with findViewById). Note that this is only practical if you know that you have a small number of list items in the adapter!
Add a empty item on list end
Example:
ArrayList<String> options = new ArrayList<String>();
String lastItem = "";
int lastPosition;
options.add(lastItem);
public function addItem() {
lastPosition = options.size() - 1;
lastItem = options.get(lastPosition);
options.remove(lastPosition);
//add new items dynamically
for (int i = 0; i < 5; i++)
options.add("new item: "+i);
//add empty item
options.add(lastItem);
}
