Just another layout issue - layout_gravity

I'm trying to implement a layout for a table-row. I have two TextViews which should be alligned to the left and one image that should be alligned to right.
Unfortunately my layout looks like this (everything is alligned to the left):
I'm fiddling with this for over an hour now and don't get it to work. What do I have to change to get the image alligned to the right?
This is my xml:
<?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="wrap_content"
android:orientation="horizontal" >
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_gravity="left"
android:orientation="vertical" >
<TextView
android:id="#+id/textView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Medium Text"
android:textAppearance="?android:attr/textAppearanceMedium" />
<TextView
android:id="#+id/textView2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Medium Text"
android:textAppearance="?android:attr/textAppearanceMedium" />
</LinearLayout>
<ImageView
android:id="#+id/imageView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center|right"
android:src="#drawable/ic_launcher" />
</LinearLayout>

You can achieve the same in LinearLayout using weight but weight is only used in making complex layouts now to avoid usage of weight, I would suggest you to transform your UI in RelativeLayout. In this way, you can save a lot of extra lines of code.
<?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="wrap_content" >
<TextView
android:id="#+id/textView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Medium Text"
android:textAppearance="?android:attr/textAppearanceMedium" />
<TextView
android:id="#+id/textView2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="#+id/textView1"
android:text="Medium Text"
android:textAppearance="?android:attr/textAppearanceMedium" />
<ImageView
android:id="#+id/imageView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:src="#drawable/ic_launcher" />
</RelativeLayout>

You can do it by using RelativeLayout
<?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="wrap_content"
>
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_alignParentLeft="true"
android:orientation="vertical" >
<TextView
android:id="#+id/textView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Medium Text"
android:textAppearance="?android:attr/textAppearanceMedium" />
<TextView
android:id="#+id/textView2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Medium Text"
android:textAppearance="?android:attr/textAppearanceMedium" />
</LinearLayout>
<ImageView
android:id="#+id/imageView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:src="#drawable/ic_launcher" />
</RelativeLayout>
or if you dont want to use RelativeLayout and want to stick with your LinearLayout then try giving weight to the first LinearLayout and layout_gravity="right|end" to the ImageView:
<?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="wrap_content"
android:orientation="horizontal" >
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_gravity="left"
android:orientation="vertical"
android:layout_weight="1" >
<TextView
android:id="#+id/textView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Medium Text"
android:textAppearance="?android:attr/textAppearanceMedium" />
<TextView
android:id="#+id/textView2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Medium Text"
android:textAppearance="?android:attr/textAppearanceMedium" />
</LinearLayout>
<ImageView
android:id="#+id/imageView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="right"
android:src="#drawable/ic_launcher" />
</LinearLayout>
Hope this works

Try using Relative layout as the root layout. In this case I think it will fix the issue.

To avoid using a RelativeLayout, you can use layout weights to set your second LinearLayout to use all the space available :
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="horizontal" >
<LinearLayout
android:layout_width="0dp"
android:layout_weight="1"
android:layout_height="match_parent"
android:gravity="left"
android:orientation="vertical" >

Use a RelativeLayout on the parent and add the android:layout_alignParentRight="true" attribute to your image

Android SDK - Positioning elements in listview row

For some reason I'm having a hell of a time with designing using eclipse and android SDK. Making layouts is painfully hard and not as easy as WPF/Visual Studio.
I am trying to accomplish the following:
Top: what I have
Bottom: what I want to achieve
http://imgur.com/AsaTuGq
Current code:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:padding="10dip"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<TextView
android:textIsSelectable="false"
android:id="#+id/line1"
android:layout_width="match_parent"
android:layout_height="0dp"
android:textSize="18sp"
android:layout_weight="1"
android:textStyle="bold"
/>
<TextView
android:textIsSelectable="false"
android:id="#+id/line2"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:textSize="18sp"
/>
<TextView
android:textIsSelectable="false"
android:id="#+id/line3"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_gravity="center"
android:textSize="18sp"
/>
</LinearLayout>
Edit:
I've also tried using Vertical LinearLayout within a Horizontal LinearLayout but that just produced a lot of errors.
Edit2:
What's with the negative rating?
Edit3:
Tried this link: http://android-developers.blogspot.ca/2009/02/android-layout-tricks-1.html
Replacing the image with a textview but the date just aligns with the top row.. hmm

You should use a RelativeLayout:
<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="wrap_content"
tools:context=".MainActivity" >
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_alignParentRight="false"
android:layout_alignParentTop="true"
android:orientation="vertical" >
<TextView
android:id="#+id/textView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Medium Text"
android:textAppearance="?android:attr/textAppearanceMedium" />
<TextView
android:id="#+id/textView2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Medium Text"
android:textAppearance="?android:attr/textAppearanceMedium" />
</LinearLayout>
<TextView
android:id="#+id/textView3"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:layout_centerVertical="true"
android:text="Medium Text"
android:textAppearance="?android:attr/textAppearanceMedium" />
</RelativeLayout>

I would suggest a RelativeLayout for this
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:padding="10dip"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<TextView
android:textIsSelectable="false"
android:id="#+id/line1"
android:layout_width="wrap_content"
android:layout_height="0dp"
android:textSize="18sp"
android:layout_weight="1"
android:textStyle="bold"
android:layout_alignParentLeft="true"
/>
<TextView
android:textIsSelectable="false"
android:id="#+id/line2"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:textSize="18sp"
android:layout_alignParentLeft="true"
android:layout_below="#_id/line1"
/>
<TextView
android:textIsSelectable="false"
android:id="#+id/line3"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:gravity="center_vertical"
android:layout_alignParentRight="true"
android:textSize="18sp"
/>
</RelativeLayout>
Changes:
Changed LinearLayout to RelativeLayout used android:layout_alignParentLeft="true" for the first two lines and android:layout_below="#+id/line1" for the second line. Moved the date to the right with android:layout_alignParentRight="true" and android:gravity="center_vertical" Hope this works for what you need.

dynamic textview display in android

In my application I am showing list of datas from database in a list view.For that listview i have 1 header with 4 text views arranged horizontally..But i want this to be arranged with some space exactly between and also it should fit into every screen. Please help me.Thanks in advance.By the following code it is arranging 1 after the other without space.
My code:
<?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"
android:background="#ffffffff">
<TextView android:id="#+id/hdrdate"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Date"/>
<TextView android:id="#+id/hdrdateasc"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
/>
<TextView android:id="#+id/hdrdes"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Item"
/>
<TextView android:id="#+id/hdritemasc"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
/>
<TextView android:id="#+id/hdrprice"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Price"
/>
<TextView android:id="#+id/hdrpriceasc"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textColor="#000000"
/>
<TextView android:id="#+id/hdrtot"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Total"
/>
<TextView android:id="#+id/hdrtotasc"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textColor="#000000"
/>
</LinearLayout>

You can use layout margin for spacing between view like
android:layout_marginLeft="5dp"
android:layout_marginRight="5dp"
To fit them on the screen you can use layout_weight.Give every view weight 1 so all will be equal.You already use fill_parent for the width of your LinearLayout.
android:layout_weight="1" for every view

try this use android:layout_weight="1"in all TextView
<?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"
android:background="#ffffffff">
<TextView android:id="#+id/hdrdate"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="1"
android:textColor="#ff00ff00"
android:text="Date"/>
<TextView android:id="#+id/hdrdateasc"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="gffgfg"
android:textColor="#ffff0000"
android:layout_weight="1"
/>
<TextView android:id="#+id/hdrdes"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="1"
android:textColor="#FF4500"
android:text="Item"
/>
<TextView android:id="#+id/hdritemasc"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="gdgdfgsg"
android:textColor="#ff0000ff"
android:layout_weight="1"
/>
<TextView android:id="#+id/hdrprice"
android:layout_weight="1"
android:layout_width="wrap_content"
android:textColor="#ff00ff00"
android:layout_height="wrap_content"
android:text="Price"
/>
</LinearLayout>

Instead of wrap_content for widht you should use weight on your textview and weightsum on linear layout:
<?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"
android:background="#ffffffff"
android:weightSum="100.0">
<TextView android:id="#+id/hdrdate"
android:layout_width="0dp"
android:layout_weight="100/number of text views"
android:layout_height="wrap_content"
android:layout_marginLeft="2dp"
android:layout_marginRight="2dp"
android:text="Date"/>
....
</LinearLayout>
If you do not want to use exact values for your margins you should add some blank text views and set the weight smaller than the one of the ones in which you have text.

Here is the code,
<?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"
android:background="#ffffffff">
<TextView android:id="#+id/hdrdate"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Date"
android:layout_weight="1"
android:gravity="center_horizontal"/>
<TextView android:id="#+id/hdrdateasc"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
<TextView android:id="#+id/hdrdes"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Item"
android:layout_weight="1"
android:gravity="center_horizontal"/>
<TextView android:id="#+id/hdritemasc"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
<TextView android:id="#+id/hdrprice"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Price"
android:layout_weight="1"
android:gravity="center_horizontal"/>
<TextView android:id="#+id/hdrpriceasc"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textColor="#000000" />
<TextView android:id="#+id/hdrtot"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Total"
android:layout_weight="1"
android:gravity="center_horizontal"/>
<TextView android:id="#+id/hdrtotasc"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textColor="#000000" />
</LinearLayout>

How to make layout of an image and text left and under it?

I need to make a layout which is specific to webpage and it needs to look like a web article with an image and a text left to and under it. Look at the image.
As this is an easy thing to do in a web world, I am not sure how to do it in XML layout.
Obviously, the TextView must be on the left while the image is present, and after it reaches the bottom of the image, it has to stretch to the screen width. I tried this with two TextViews (one for left and another for bottom), but it just does not look right due to the text font size.
EDIT
I also tried to dinamically catch the height of image and then assign it to my TextView, and then make another TextView with the size of the screen under these two elements. This does not work as well as I cannot control the text that is not visible due to limited height of the first TextView.

If you haven't found the answer yet. Here is the same kind of question that is being answered.
How to align TextView around an ImageView?
The only thing what you might have to change in your case is to, make the alignment to be opposite way.
<?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="wrap_content"
android:padding="5dp">
<TextView
android:textSize="18.0sp"
android:id="#+id/message_view"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="#string/text" />
<ImageView
android:src="#drawable/icon"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_toRightOf="#+id/message_view"
android:id="#+id/icon" />

use this way layout
<?xml version="1.0" encoding="utf-8"?>

android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:layout_alignParentTop="true"
android:layout_marginRight="21dp"
android:src="#drawable/ic_launcher" />
<TextView
android:id="#+id/textView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_toLeftOf="#+id/imageView1"
android:layout_marginLeft="30dp"

<TextView
android:id="#+id/textView2"

android:layout_marginLeft="30dp"
android:text="TextViewaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa"
android:layout_alignBottom="#+id/textView1"></TextView>
</RelativeLayout>
And add in code
TextView tv1=(TextView)findViewById(R.id.textView1);
tv1.setMaxHeight(maxHeight);
where maxHeight is dynamically get height of imageview
and than put condition to by getting height of textview1 to assign text to second textview
may it helps u
like this am I right?

Android: 3 TextViews, middle one should be vertically centered

i'm struggling with a layout issue at the moment.
In fact i need 3 TextViews: one at the top, one in the middle, one at the bottom.
The middle one should fill the screen, the top & bottom one should only get as much space as they need for showing the text.
How to realize this layout?

You could also do this with a LinearLayout:
<?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:orientation="vertical" >
<TextView
android:id="#+id/textView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="TextView" />
<TextView
android:id="#+id/textView2"
android:layout_width="wrap_content"
android:layout_height="0dp"
android:layout_weight="1"
android:text="TextView"/>
<TextView
android:id="#+id/textView3"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="TextView" />
</LinearLayout>

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent" android:id="#+id/l1"
android:layout_height="fill_parent" android:orientation="vertical">
<TextView android:layout_width="wrap_content"
android:layout_alignParentTop="true" android:id="#+id/textView1"
android:layout_height="wrap_content" android:text="TextView"
android:layout_alignParentLeft="true"></TextView>
<TextView android:layout_alignParentBottom="true"
android:layout_width="wrap_content" android:id="#+id/textView3"
android:layout_height="wrap_content" android:text="TextView"
></TextView>
<TextView android:layout_centerInParent="true"
android:layout_below="#id/textView1" android:gravity="center_vertical|center_horizontal"
android:layout_width="fill_parent" android:id="#+id/textView2"
android:layout_above ="#id/textView3" android:layout_height="fill_parent"
android:text="TextssssssssssssssssView"
android:layout_alignParentLeft="true" ></TextView>
</RelativeLayout>
