place a linearLayout in center of a wrap_content relativeLayout

I have a listView, and view of each item of the list should be like this (a background image and group name) :
but when i set layout_centerInParent="true" to linearLayout, it placed in center of screen(not in center of image).like this :
and there is my xml :
<?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:background="#444">
<ImageView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:adjustViewBounds="true"
android:src="#drawable/test"/>
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:background="#drawable/linear_category_name"
android:paddingTop="10dp"
android:paddingBottom="10dp"
android:paddingRight="16dp"
android:paddingLeft="16dp">
<ir.dbasoft.test.myobject.MyTextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textColor="#android:color/white"
android:textSize="18sp"
android:text="Gold"/>
</LinearLayout>
</RelativeLayout>
How can i place linearLayout in center of relaytiveLayout ??

For your scenario, I think it's a lot easier to use FrameLayout instead.
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<ImageView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:adjustViewBounds="true"
android:src="#drawable/gold_image"/>
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:background="#drawable/white_border"
android:orientation="vertical"
android:padding="8dp">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Gold"
android:textColor="#android:color/white"
android:textSize="18sp"/>
</LinearLayout>
</FrameLayout>
I've tested this and it looked exactly like what you're trying to achieve.

Try this.
<?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:background="#444">
<ImageView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:adjustViewBounds="true"
android:src="#drawable/test/>
<ir.dbasoft.test.myobject.MyTextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textColor="#android:color/white"
android:textSize="18sp"
android:text="Gold"
android:layout_centerVertical="true"
android:layout_centerHorizontal="true" />
</RelativeLayout>

Try this
<ImageView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:adjustViewBounds="true"
android:layout_centerInParent="true"
android:src="#drawable/test"/>
<ir.dbasoft.test.myobject.MyTextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textColor="#android:color/white"
android:textSize="18sp"
android:layout_centerInParent="true"
android:text="Gold"/>

Android textview on imageview

I am trying to place an TextView on a ImageView in the bottom center of the RelativeLayout.
I am able to place the TextViewin the center but not able to place it in the bottom .
Can anyone guide me.
here is my XML
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/back"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<ImageView
android:id="#+id/eventimage"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:scaleType="fitXY"
android:background="#000000">
</ImageView>
<TextView
android:id="#+id/text98"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:gravity="center"
android:layout_centerVertical="true"
android:singleLine="true"
android:textColor="#color/white"
android:text="LAST"
android:textStyle="bold"
android:textSize="18sp"/>
</RelativeLayout>

on the textView use the following attributes android:layout_centerHorizontal="true" instead of android:layout_centerVertical="true" and add android:alignParentBottom=true". Also look at the relative layout options to understand how to work with it.

try
<TextView
android:layout_alignParentBottom="true"
...

You could try using something like
android:layout_alignBaseline (#id/eventimage);
and add some padding on the bottom later

You can use this
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/back"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<ImageView
android:id="#+id/eventimage"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:scaleType="fitXY"
android:background="#000000">
</ImageView>
<TextView
android:id="#+id/text98"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:gravity="center_horizontal"
android:singleLine="true"
android:textColor="#color/white"
android:text="LAST"
android:layout_alignParentBottom="true"
android:textStyle="bold"
android:textSize="18sp"/>
</RelativeLayout>

Add this to your TextView:
android:layout_alignBottom="#id/eventimage"

Use this code:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/back"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<ImageView
android:id="#+id/eventimage"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:scaleType="fitXY"
android:background="#000000">
</ImageView>
<TextView
android:id="#+id/text98"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="center"
android:layout_alignParentBottom="true"
android:alignBottom="#+id/eventimage"
android:singleLine="true"
android:textColor="#color/white"
android:text="LAST"
android:textStyle="bold"
android:textSize="18sp"/>
</RelativeLayout>
Hope it will help you.

Try the following:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/back"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<ImageView
android:id="#+id/eventimage"
android:layout_alignParentBottom="true"
android:layout_centerHorizontal="true"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:scaleType="fitXY"
android:background="#000000">
</ImageView>
<TextView
android:id="#+id/text98"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="center"
android:layout_alignParentBottom="true"
android:layout_centerHorizontal="true"
android:singleLine="true"
android:textColor="#color/white"
android:text="LAST"
android:textStyle="bold"
android:textSize="18sp"/>
</RelativeLayout>

This layout works according to your requirement .by setting the gravity bottom of the linear layout ,its chilld view is automatically aligned at center- bottom position
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/back"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical"
android:background="#drawable/ic_launcher"
android:gravity="bottom">
<TextView
android:id="#+id/text98"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_centerVertical="true"
android:gravity="center"
android:singleLine="true"
android:text="LAST"
android:textSize="18sp"
android:textStyle="bold"
android:textColor="#android:color/white"/
>
</LinearLayout>

android:layout_alignParentBottom to move the control to the bottom of the screen.

how to reduce distance between both text in listview?

Hi I'm newly entered in this project. How to reduce listview text view distance please...
xml 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"
android:orientation="horizontal" >
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/thumb"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:padding="3dip"
android:layout_alignParentLeft="true"
android:layout_marginRight="5dip">
<ImageView
android:id="#+id/img"
android:layout_width="wrap_content"
android:layout_height="wrap_content"/>
</LinearLayout>
<TextView
android:id="#+id/title"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignTop="#+id/thumb"
android:layout_toRightOf="#+id/thumb"
android:layout_centerVertical="true"
android:layout_marginTop="1000dip"
android:textColor="#ffffff"/>
<TextView
android:id="#+id/detail"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_toRightOf="#+id/thumb"
android:layout_alignParentBottom="true"
android:textColor="#ffffff" />
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/imgArrow"
android:layout_alignParentRight="true"
android:layout_centerVertical="true"/>
</RelativeLayout>

You have given android:layout_alignParentBottom="true" to the below text.so it will set itself to the bottom of the layout.Either remove this and give marginTop to the this text or give marginTop to the above text.Here is only problem,look at it.
Use this XML as the list_item of your listview and make changes wherever needed
<?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="wrap_content"
android:orientation="vertical">
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#drawable/ic_launcher"/>
</LinearLayout>
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="vertical"
android:layout_marginTop="5dp">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="aaaaaaaaaaaaaaaaa"/>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="bbbbbbbbbbbbbbb"/>
</LinearLayout>
</LinearLayout>
i dont know whether this is the only reqirement of yours though i have tried to shorten the distance between them.Try it n Hope this will help you.

Positioning ImageView

I need to positioning the ImageView at the same level of the user's name (vito in the example).
This is what I have:
And I want this (look at the second icon):
My xml:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_height="wrap_content"
android:layout_width="fill_parent"
android:paddingBottom="5px"
android:paddingTop="5px"
android:paddingLeft="5px"
android:orientation="horizontal"
style="#style/ListRow">
<ImageView
android:id="#+id/imagenItem"
android:layout_width="wrap_content"
android:layout_height="fill_parent"
android:layout_marginRight="6dip"
android:layout_gravity="top"
android:gravity="top"
android:layout_alignParentTop="true"
style="#style/iconLISTA" />
<LinearLayout
android:orientation="vertical"
android:layout_width="0dip"
android:layout_weight="1"
android:layout_height="fill_parent">
<RelativeLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="horizontal">
<TextView
android:id="#+id/idUsuario"
android:textSize="#dimen/font_size_small"
android:textStyle="bold"
android:textColor="#color/list_item_text"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"/>
<TextView
android:id="#+id/hora"
android:textSize="#dimen/font_size_small"
android:textStyle="bold"
android:textColor="#color/list_item_secondary_text"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_marginLeft="215px" />
</RelativeLayout>
<TextView
android:id="#+id/comentarios"
android:textSize="#dimen/font_size_small"
android:color="#color/list_item_text"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_marginLeft="0px" />
</LinearLayout>
</LinearLayout>
Thanks.

Change the ImageView and following LinearLayout hight attributes to both be wrap_content.
The ImageView is currently fill_parent which is making it take all available vertical space and centering it vertically.

Add:
android:scaleType="fitStart"
to the ImageView layout.
e.g.
<ImageView
android:id="#+id/imagenItem"
android:scaleType="fitStart"
android:layout_width="wrap_content"
android:layout_height="fill_parent"
android:layout_marginRight="6dip"
android:layout_gravity="top"
android:gravity="top"
android:layout_alignParentTop="true"
style="#style/iconLISTA" />

Try this, is bit simplified:
<?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"
android:padding="5dp" >
<ImageView
android:id="#+id/imagenItem"
android:layout_width="50dp"
android:layout_height="50dp"
android:layout_gravity="top"
android:scaleType="fitCenter"
android:src="#drawable/avatar_default" />
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_marginLeft="5dp"
android:orientation="vertical" >
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="horizontal" >
<TextView
android:id="#+id/idUsuario"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:gravity="left"
android:text="usuario"
android:textStyle="bold" />
<TextView
android:id="#+id/hora"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:gravity="right"
android:text="hora"
android:textStyle="bold" />
</LinearLayout>
<TextView
android:id="#+id/comentarios"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="commmmment" />
</LinearLayout>
</LinearLayout>
And you shouldn't use px, use always dp/dip.

Android linear layout align center and right

This is what I have:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout android:id="#+id/LinearLayout01"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:background="#FFFFFF">
<LinearLayout android:id="#+id/LinearLayout01"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="horizontal"
android:background="#E30000"
android:layout_gravity="center_horizontal|center_vertical"
android:gravity="center_horizontal|center_vertical">
<TextView
android:id="#+id/TextView00"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textColor="#FFFFFF"
android:textSize="20px"
android:textStyle="bold"
android:text="Something"
android:gravity="right|center_vertical"
/>
<LinearLayout android:id="#+id/LinearLayout01"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="horizontal"
android:gravity="right|center_vertical"
android:layout_gravity="center_vertical"
android:background="#E30000">
<Button
android:id="#+id/btnCalls"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:drawableLeft="#drawable/icon"
android:gravity="right|center_vertical"
/>
</LinearLayout>
</LinearLayout>
</LinearLayout>
And I want this:
So horizontal center align the text and vertical center align the button.
What am I missing? I haven't tried RelativeLayout and I would prefer LinearLayout to work this out.

android:gravity="right|center_vertical"
aligns your TextView to the right. How about center_horizontal?
And your LinearLayouts have the same ID, if there is not more code, then I would delete one of them.

try this one
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout android:id="#+id/LinearLayout01"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:background="#FFFFFF">
<LinearLayout android:id="#+id/LinearLayout01"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="horizontal"
android:background="#E30000"
android:layout_gravity="center_horizontal|center_vertical"
android:gravity="center_vertical">
<TextView
android:id="#+id/TextView00"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textColor="#FFFFFF"
android:textSize="20px"
android:textStyle="bold"
android:text="Something"
android:layout_weight="1"
android:gravity="center"/>
<LinearLayout android:id="#+id/LinearLayout01"
android:layout_height="wrap_content"
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="horizontal"
android:gravity="right|center_vertical"
android:layout_gravity="center_vertical"
android:background="#E30000"
android:layout_width="wrap_content">
<Button
android:id="#+id/btnCalls"
android:layout_width="wrap_content"
android:drawableLeft="#drawable/icon"
android:gravity="right|center_vertical"
android:layout_height="wrap_content"
android:layout_margin="5dip"/>
</LinearLayout>
</LinearLayout>
</LinearLayout>

I found none of the answers work exactly as the OP intended, but the RelativeLayout solution was the closest one. Except that the TextView wasn't centered. But, with layout_centerInParent=true, works like a charm:
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<TextView
android:id="#+id/TextView00"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textColor="#FFFFFF"
android:textSize="20px"
android:textStyle="bold"
android:text="Something"
android:layout_centerInParent="true" />
<Button
android:id="#+id/btnCalls"
android:drawableLeft="#drawable/icon"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"/>
</RelativeLayout>

you have used android:gravity="right|center_vertical" in your textview. Use android:gravity="center".

Try to add empty View inside horizontal LinearLayout between element that you want see left and element that you want to see right, e.g.:
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content" >
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
<View
android:layout_width="0dp"
android:layout_height="0dp"
android:layout_weight="1"
/>
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
</LinearLayout>

define layout weight for TextView and LinearLayout
set android:layout_weight="1" to TextView
set android:layout_weight="0" to LinearLayout
and also change the layout_width="wrap_content" to LinearLayout
and set layout_gravity="center" to TextView

I think,gravity means the position of things inside the component(for textview,it means the text you have given)in component where layout_gravity means position of component itself in the whole layout.So...
Try Using:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout android:id="#+id/LinearLayout01"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:background="#FFFFFF"
>
<LinearLayout android:id="#+id/LinearLayout01"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="horizontal"
android:background="#E30000"
android:layout_gravity="right"
android:gravity="center_vertical|right"
>
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="right|center_vertical"
android:gravity="center_vertical|center"
android:layout_weight="0.9"
>
<TextView
android:id="#+id/TextView00"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textColor="#FFFFFF"
android:textSize="20px"
android:textStyle="bold"
android:text="Something"
android:gravity="center_horizontal"
android:layout_gravity="center_horizontal|center_vertical"
/>
</LinearLayout>
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="right|center_vertical"
android:gravity="center_vertical|right"
android:paddingTop="5dip"
android:layout_weight="0.1"
>
<Button
android:id="#+id/btnCalls"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:drawableLeft="#drawable/icon"
android:layout_gravity="center_vertical"
android:gravity="center"
/>
</LinearLayout>
</LinearLayout>
</LinearLayout>

Just use RelativeLayout, and wallaaa!!!
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<TextView
android:id="#+id/TextView00"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textColor="#FFFFFF"
android:textSize="20px"
android:textStyle="bold"
android:text="Something"
android:gravity="center" />
<Button
android:id="#+id/btnCalls"
android:drawableLeft="#drawable/icon"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"/>
</RelativeLayout>

The solution for this is-
android:gravity="center_vertical"
Normally you'll also have to take care of its parent's position too to make sure it works.
