Android :: Need Place To Gridview Padding Or Imageview?
Oct 16, 2009
I'm doing the HelloViews Gridview tutorial and I ran into this problem.
http://grab.by/9Vn
I have a padding that I can't find where is it coming from.
XML is the following: <?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:numColumns="2" android:verticalSpacing="0px" android:horizontalSpacing="0px" android:stretchMode="columnWidth"android:gravity="center" android:layout_margin="0dp" />
and in my adapter:
I can't seem to find the place where I can get rid of that padding (or margin). Pictures are 160px x 160px.

I have an ImageView, and I want it to be clickable. The image itself is only 32x32 pixels, but I want the clickable region to be larger so it's easier to hit. I was hoping I could set the layout margin values to increase the size of the imageview's clickable area:
<ImageView
layout_width="32dip"
layout_height="32dip"
layout_margin="20dip" />
That doesn't work, what I could do is just recreate the image resource to have a larger transparent region around it. That's a bit annoying because it's hard to tweak if I ever need to change the clickable region. It's not just a single png either, it's a statelistdrawable so I have to resize 3 different pngs if I ever need to tweak the clickable area.
Anything else I can do?

With my current code the bottom image is not displaying at all. Also I would like to stick the bottom image "bottomboxes" to the bottom of the display.

I have a problem with rendering a ScrollView. Essentially, the layout is fixed header and footer with a scrollview in the middle. The idea is that when the screen keyboard is activated for the content EditText the image can be scrolled if the height of the image is longer than the middle view.
In testing the layout, I've found that on my Android phone (Xperia X10 Android 1.6) there is a whole heap of padding added to the top and bottom of the ImageView.
How I can prevent this from happening.

I have a horizontal LinearLayout. This LinearLayout has a checkbox next to another LinearLayout. The layout width/height of the checkbox is wrap_content, whereas the inner LinearLayout is fill_parent/wrap_content. The layout_weight of the inner LinearLayout is set to 1.
I've tried to add some android:padding around the checkbox to give some space around it, but no padding is given. I've also tried android:paddingLeft/Right/etc. How do I get some padding around my checkbox?
Note: I have an inner LinearLayout because I will be adding more TextViews
<?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="?android:attr/listPreferredItemHeight">
<CheckBox
android:id="@+id/mycheck"
android:text=""
android:layout_width="30dip"
android:layout_height="wrap_content"
android:gravity="center_vertical"
android:focusable="false"
android:background="@drawable/checkbox_background"
android:button="@drawable/checkbox"
/>
<LinearLayout
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_weight="1"
android:layout_height="wrap_content">
<TextView
android:id="@+id/mytext"
android:layout_width="fill_parent"
android:layout_weight="1"
android:gravity="center_vertical"
android:layout_height="wrap_content"
android:lines="1"
android:textColor="@color/white"
android:textSize="10sp"
android:textStyle="italic"/>
</LinearLayout>
</LinearLayout>

I am creating an application that checks the installation of a package and then launches the market-place with its id.
When I try to launch market place with id of an application say com.mybrowser.android by throwing an intent android.intent.action.VIEW with url: market://details?id=com.mybrowser.android, the market place application does launches but crashes after launch.

MyApplication is my application.

I'm using xml file to define progress bar. I defined padding on background shape. But this setting will be sometimes displayed correctly, sometimes not. So If I start my application or Activity with progressbar inside, there will be correctly displayed progressbar with background and 'padded' progress. Then I close my application and start it again, and, progressbar is displayed without padded background, on next start will be displayed correctly and son on ... Could you please advice possible reasons for this?

I have a list where i basically need a hierarchy of items. Any children of an item would be padded slightly, as to easily distinguish their parent item. How could this be achieved? Note that i could, if needed, make each parent show no children, and then when the parent is clicked, a new list containing all of it's children is loaded. This however requires more clicking to display information than i would prefer. Also, the items themselves will contain graphics and whatnot (to show a drag'n'drop button, etc), so it would be best if it visually appeared as if the item itself had a margin, rather than the contents of the item being padded.

I have a linear layout which has a background image (a 9 patched png file). How can I add padding to left and right so that the background image does not take up the whole width? I have tried 'android:paddingLeft' and 'android:paddingRight', but that does not change anything.
CODE:.....
The whole background still stretches the whole screen width.

I'm following an example where the author hard coded a paddingTop to 370px. How do I make that paddingTop dynamic? When I run this in 2 AVDs with HVGA and WVGA80 I get the frame floating at different heights. I'd like to say something like paddingTop=80%, but that doesn't work.

I have a 3*3 TableLayout that contains buttons. But I cannot seem to remove the spacing between the buttons in the Table.Setting pading to zero for the buttons has no effect. Setting padding and layout_margin to zero for the TableRow has no effect. Setting layout_margin for the TableLayout has no effect.Any idea on how I can alter/remove/reduce the spacing between the cells?

I have a shape with a gradient that I'm using as a divider between ListView items. I've defined it as follows:
<?xml version="1.0" encoding="UTF-8"?>
<shape
xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<gradient
android:startColor="#ccd0d3"
android:centerColor="#b6babd"
android:endColor="#ccd0d3"
android:height="1px"
android:angle="0" />
</shape>
I would like to add 6 pixels of padding on either side of the gradient, so that it doesn't extend from edge to edge of the screen.
However, no matter where I put an android:left="6px" and android:right="6px", it doesn't seem to take effect. I can put it in the <shape> element, the <gradient> element, or in a separate <padding> child of <shape>, and it doesn't change anything.
How can I add padding on the left and right of my list divider?

I am trying to set padding in shape declared in XML file. But whatever I set, nothing changes related to padding. If I modify any other properties, I see updated UI. But it doesn't work with padding. Could you please advice possible reasons for this?
I will provide below example of my shape.xml:
<shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="rectangle">
<stroke android:width="1dp" android:color="#ffffff" android:dashWidth="2dp"/>
<solid android:color="@color/button_white_cover" />
<corners android:radius="11dp" />
<padding android:left="1dp" android:top="20dp"
android:right="20dp" android:bottom="2dp" />
</shape>

Say I add a linear layout with top padding of 20. Does it mean that the layout is rendered with 20 pixels of padding in all phones? Or does it scale according to the height/width/density of the phone?

As you can see in the link below there is an extra padding (around 2mm) below the EditText field. I can't seem to remove this padding in anyway. This occurs with other widgets as well (like Buttons). It looks like Android is default adding this extra padding to all elements.

Here is a skeleton of the class I'm currently working on. Unfortunatly, i'm stuck on two problems and it's driving me mad !
The first problem is about the onKeyDown(KeyEvent) : I don't understand why this method isn't called while I pressed a key on the emulator. The second problem deals with padding. Indeed, I'm always creating widget using fake paddings in order to be sure my widget correctly handle those values. Unfortunatly, I tried to extend a ProgressBar and I had some problems because my ProgressBar is clipped.
My code is :
package com.niji.android.myhouse;
import android.content.Context; import android.graphics.Canvas; import android.graphics.Color; import android.graphics.Paint; import android.graphics.drawable.Drawable; import android.util.AttributeSet; import android.util.Log; import android.view.KeyEvent; import android.view.MotionEvent; import android.widget.ProgressBar; Code...
