Android widgets layout setup - android

In my app i have a custom dialog whose layout is like the following:
<?xml version="1.0" encoding="utf-8"?>
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content" android:layout_height="wrap_content" android:orientation="vertical"
android:scrollbars = "vertical"
android:scrollbarAlwaysDrawVerticalTrack = "true"
android:padding="10dp" >
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent" android:layout_height="wrap_content" android:orientation="horizontal" >
<TextView android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="blablabla...."/>
<ImageView android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_marginRight="10dp" android:src="#drawable/book1"/>
</LinearLayout>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent" android:layout_height="wrap_content" android:orientation="horizontal" >
<TextView android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="blablablablablablablablabla..."/>
<ImageView android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_marginRight="10dp" android:src="#drawable/book2"/>
</LinearLayout>
</LinearLayout>
</ScrollView>
That is, i show a list of two horizontally placed widgets: a TextView showing some text and an, adjacent to the text, an ImageView widget showing an image.
What i would like to do is to show the ImageView widgets in such a way that they are aligned, that is, the image 1 start at the same column of image 2.
How can i do that?
Thx!


I'm not exactly sure what you are hoping for, but I would do the following:
<?xml version="1.0" encoding="utf-8"?>
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="vertical"
android:padding="10dp"
android:scrollbarAlwaysDrawVerticalTrack="true"
android:scrollbars="vertical" >
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="blablabla...." />
<ImageView
android:id="#+id/image1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginRight="10dp"
android:layout_alignParentRight="true"
android:src="#drawable/book1" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="#+id/image1"
android:text="blablablablablablablablabla..." />
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginRight="10dp"
android:layout_below="#+id/image1"
android:layout_alignParentRight="true"
android:src="#drawable/book2" />
</RelativeLayout>
</ScrollView>
I changed it to a relative layout and used some attributes such as android:layout_below
and android:layout_alignParentRight="true to get these changes. I hope this helps.

How to align image and text exactly equal when using in gridview android?

Hi I am using Gridview to display images with text below by using custom adapter. But problem is when I fetch image and display, align gets changing and it's not proper.Here is my code:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<GridView
android:id="#+id/gridview"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:verticalSpacing="10dp"
android:horizontalSpacing="10dp"
android:stretchMode="columnWidth"
android:numColumns="3" />
</RelativeLayout>
gridview.row:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
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"
android:orientation="vertical" >
<RelativeLayout
android:id="#+id/RelativeLayout1"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<ImageView
android:id="#+id/brand_picture"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/ic_launcher"/>
<TextView
android:id="#+id/brand_name"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="#+id/brand_picture"
android:gravity="center_vertical"
android:text="TextView"
android:background="#color/blue"
android:textColor="#FFFFFF" />
How to achieve the expected output with same image size and text below that.
Expected output is:
But my output looks like this.
Thanks.

try this..hope it works for u..
<RelativeLayout
android:id="#+id/RelativeLayout1"
android:layout_width="match_parent"
android:layout_height="wrap_content" >
<ImageView
android:id="#+id/brand_picture"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_alignRight="#+id/brand_name"
android:src="#drawable/ic_launcher" />
<TextView
android:id="#+id/brand_name"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_below="#+id/brand_picture"
android:background="#color/blue"
android:gravity="center_vertical"
android:text="TextView"
android:textColor="#ffffff" />

On setting Wrap content the widget adjusts its height/width parameters to the given content size.so
change width of image view and text view from wrap content and set same width for both image view and text view.
eg:android:layout_width="70dp"
To get text in cente of text view you have to set
android:gravity="center"
xml:ROW
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
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"
android:orientation="vertical" >
<RelativeLayout
android:id="#+id/RelativeLayout1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#333333">
<ImageView
android:id="#+id/brand_picture"
android:layout_width="90dp"
android:layout_height="wrap_content"
android:background="#499999"
android:src="#drawable/ic_launcher"/>
<TextView
android:id="#+id/brand_name"
android:layout_width="90dp"
android:layout_below="#+id/brand_picture"
android:gravity="center"
android:text="AQUA LUNG"
android:background="#445657"
android:textColor="#FFFFFF" />

Add property,
android:layout_centerHorizontal="true"
to your ImageView as well as TextView. It will work.

You can try this layout:
Actually i have replaced your relative layout with linear layout, but it works just like what you want.
<LinearLayout
android:id="#+id/RelativeLayout1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="vertical" >
<ImageView
android:id="#+id/brand_picture"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/ic_launcher"
android:layout_gravity="center" />
<TextView
android:id="#+id/brand_name"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#color/blue"
android:text="TextView"
android:textColor="#FFFFFF" />
</LinearLayout>
Hope this resolves your issue....

<RelativeLayout
android:id="#+id/RelativeLayout1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#000000">
<ImageView
android:id="#+id/brand_picture"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/ic_launcher"/>
<TextView
android:id="#+id/brand_name"
android:layout_width="90dp"
android:layout_height="wrap_content"
android:layout_alignLeft="#+id/brand_picture"
android:layout_alignRight="#+id/brand_picture"
android:layout_below="#+id/brand_picture"
android:background="#445657"
android:gravity="center"
android:text="WHATEVER"
android:textColor="#FFFFFF" />
</RelativeLayout>
Or You can try
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"

<ImageView
android:id="#+id/brand_picture"
android:layout_width="wrap_content"

View is overlapped by another view with match_parent and wrap_content on Android

I want to create a view with two parts:
1. Avatar, which is always displayed at right/center_vertial on screen.
2. Name, which is always displayed at left on screen (do not overlap on Avatar).
<?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="horizontal" >
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:orientation="vertical">
<TextView
android:id="#+id/name"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/username" />
</LinearLayout>
<LinearLayout
android:id="#id/avatar"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:gravity="right|center_vertical"
android:orientation="vertical" >
<ImageView
android:id="#+id/avatar"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="right|center_vertical"
android:scaleType="center"
android:src="#drawable/useravatar" />
</LinearLayout>
</LinearLayout>
The problem is when Name is too long, it overlaps on Avatar. How can I fix this problem?

You should use RelativeLayout and a android:layout_toLeftOf="#id/avatar" attribute for the TextView.

You're better off using a Relative Layout for this:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/RelativeLayout1"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="horizontal" >
<TextView
android:id="#+id/name"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_alignParentTop="true"
android:layout_toLeftOf="#+id/avatar"
android:text="Some User Name" />
<ImageView
android:id="#+id/avatar"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:layout_alignParentTop="true"
android:layout_gravity="right|center_vertical"
android:scaleType="center"
android:src="#drawable/thumbr" />
</RelativeLayout>

Align a layout to the top of another layout in order to make a status bar

I have a layout like this:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/parent"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#e4e8ed"
android:gravity="top" >
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/app"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_margin="0px"
android:orientation="vertical"
android:padding="0px" >
<include
android:id="#+id/tabBar"
layout="#layout/tab" />
<Button
android:id="#+id/nist"
android:layout_width="match_parent"
android:layout_height="67dp"
android:layout_gravity="center_horizontal"
android:layout_marginBottom="3dp"
android:layout_marginLeft="3dp"
android:layout_marginRight="3dp"
android:layout_marginTop="3dp"
android:background="#drawable/ready"
android:textColor="#FFFFFF" />
<ListView
android:id="#+id/lastCases"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_weight="2.08"
android:longClickable="true" />
</LinearLayout>
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="7dp"
android:layout_below="#id/app"
android:background="#drawable/dropshadow_custom" >
<TextView
android:id="#+id/error"
style="#style/AudioFileInfoOverlayText"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_marginTop="120dp"
android:gravity="center"
android:text="No Cases"
android:textAppearance="?android:attr/textAppearanceLarge"
android:textColor="#D6D8D9"
android:textSize="40dp" />
</LinearLayout>
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_alignParentRight="true"
android:layout_alignTop="#+id/app"
android:background="#000000"
android:gravity="bottom"
android:orientation="vertical" >
</LinearLayout>
</RelativeLayout>
I try to align the last LinearLayout on top of the layout which holds the ListView by using this tag: android:layout_alignTop="#+id/app" But it doesn't seem to work. How can accomplish this?
Many Thanks!

Without any content a Layout with layout_width="wrap_content" and layout_height="wrap_content" is not shown as its width and height have a value of 0! Even if you have set some background color nothing will appear! You either have to add some content to the layout or you have to define another layout dimension. The position of your layout with android:layout_alignTop="#+id/app" should be correct. Hope that helps.

You can set "layout_below" on the first layout targeting to the last layout.
The code is that, I put a button inside the top layout as an exemple (Obs: In your listview you should use 0dp in layout_weight cause you already use layout_weight ^^) :
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/parent"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#e4e8ed"
android:gravity="top" >
<LinearLayout
android:id="#+id/app"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_margin="0px"
android:orientation="vertical"
android:layout_below="#+id/top"
android:padding="0px" >
<Button
android:id="#+id/nist"
android:layout_width="match_parent"
android:layout_height="67dp"
android:layout_gravity="center_horizontal"
android:layout_marginBottom="3dp"
android:layout_marginLeft="3dp"
android:layout_marginRight="3dp"
android:layout_marginTop="3dp"
android:textColor="#FFFFFF" />

Android LinearLayouts conflicting with each other

I have two LinearLayout
One contains a EditText with a patch9 image as a speech bubble and another with a TextView and ImageView
When I try typing into the EditText is begins to expand towards the right hand side then starts to reduce the width of the second LinearLayout (crushing the image)
XML is
<?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:background="#color/white"
android:gravity="center"
android:orientation="vertical" >
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:gravity="center"
android:orientation="horizontal" >
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="1"
android:gravity="left"
android:orientation="vertical" >
<EditText
android:id="#+id/summaryMessage"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#drawable/greeting_bubble_white"
android:gravity="center" />
</LinearLayout>
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="1"
android:gravity="right"
android:orientation="vertical" >
<ImageView
android:id="#+id/summaryImage"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#drawable/picture_frame" />
<TextView
android:id="#+id/summaryText"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:gravity="center"
android:paddingLeft="10dp" />
</LinearLayout>
</LinearLayout>
</LinearLayout>
Looks like this
Any ideas?

its expanding since you have specified that layout_width of your LinearLayout should be "wrap_content", you should specify a fixed dimension with dps so it doesn't expand beyond.
Alternative use the weight tag
try out this modification:
<?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:background="#color/white"
android:gravity="center"
android:orientation="vertical" >
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:gravity="center"
android:orientation="horizontal"
android:layout_weight="0.7">
<EditText
android:id="#+id/summaryMessage"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#drawable/greeting_bubble_white"
android:gravity="center" />
</LinearLayout>
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="0.3"
android:gravity="right"
android:orientation="vertical" >
<ImageView
android:id="#+id/summaryImage"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#drawable/picture_frame" />
<TextView
android:id="#+id/summaryText"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:gravity="center"
android:paddingLeft="10dp" />
</LinearLayout>
however I would suggest more that you use this one:
<?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:background="#color/white"
android:gravity="center"
android:orientation="horizontal" >
<EditText
android:id="#+id/summaryMessage"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_weight="0.7"
android:background="#drawable/greeting_bubble_white"
android:gravity="center" />
<TextView
android:id="#+id/summaryText"
android:layout_weight="0.3"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:gravity="center"
android:paddingLeft="10dp" />
</LinearLayout>
and that you use compound drawables on your summaryText here is a link that should help you: Using Compund Drawables

Use a relative layout, the layout editor is in fact pretty good so use it to position your views

issue with a android linear layout

i have a problem with the linear layout of android.
i have something like 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" >
<ImageView
android:id="#+id/imageView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/myimg"
android:contentDescription="#string/desc" />
<TextView
android:id="#+id/textView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/a" />
<EditText
android:id="#+id/editText1"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:inputType="number" />
</LinearLayout>
the problem is, that on some bigger devices everything is good. but on smaler devices i just see the image and the textview and edittext is not visible. and its not possible to scroll down.
how to avoid this?

Put the whole thing into a ScrollView. Nothing easier than that!
<?xml version="1.0" encoding="utf-8"?>
<ScrollView
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<ImageView
android:id="#+id/imageView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/myimg"
android:contentDescription="#string/desc" />
<TextView
android:id="#+id/textView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/a" />
<EditText
android:id="#+id/editText1"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:inputType="number" />
</LinearLayout>
</ScrollView>

It is because LinearLayout is not supposed to scroll down automatically. If you want to make your views scroll, you should place the layout inside a ScrollView:
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<ImageView
android:id="#+id/imageView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/myimg"
android:contentDescription="#string/desc" />
<TextView
android:id="#+id/textView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/a" />
<EditText
android:id="#+id/editText1"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:inputType="number" />
</LinearLayout>
</ScrollView>
