How to move the ImageView extreme right in android LinearLayout?

This is my xml. I need to place my icon to extreme right. But it's not moving to extreme right. "tri_logo" I have given gravity as right. But still not moving to right.
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/toplayout"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:clickable="true"
android:orientation="vertical" >
<LinearLayout
android:id="#+id/lout_profile_header"
android:layout_width="match_parent"
android:layout_height="#dimen/top_view_height"
android:clickable="true"
android:gravity="center"
android:orientation="horizontal">
<com.test.customviews.CircleImageView
android:id="#+id/imgTopProfile"
android:layout_width="#dimen/profilie_icon_size"
android:layout_height="#dimen/profilie_icon_size"
android:layout_margin="#dimen/hdr_img_padding"
android:src="#mipmap/ic_profile" />
<TextView
android:id="#+id/textTopProfile"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_vertical"
android:layout_marginLeft="#dimen/hdr_name_padding" />
<ImageView
android:id="#+id/tri_logo"
android:layout_width="30dp"
android:layout_height="30dp"
android:layout_gravity="right"
android:src="#drawable/tri_logo"/>
</LinearLayout>
</LinearLayout>
ImageView tri_logo is not moving to right.

Try this
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/toplayout"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:clickable="true"
android:orientation="vertical">
<LinearLayout
android:id="#+id/lout_profile_header"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:clickable="true"
android:weightSum="3"
android:layout_gravity="right"
android:orientation="horizontal">
<com.test.customviews.CircleImageView
android:id="#+id/imgTopProfile"
android:layout_weight="1"
android:layout_width="#dimen/profilie_icon_size"
android:layout_height="#dimen/profilie_icon_size"
android:layout_margin="#dimen/hdr_img_padding"
android:src="#mipmap/ic_profile" />
<TextView
android:layout_weight="1"
android:id="#+id/textTopProfile"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_vertical"
/>
<ImageView
android:layout_weight="1"
android:id="#+id/tri_logo"
android:layout_width="30dp"
android:layout_height="30dp"
android:layout_gravity="right"
android:src="#drawable/voyage"/>
</LinearLayout>
</LinearLayout>
You could use RelativeLayout and then use layout_alignParentEnd=true, if you want to stick on to LinearLayout try above one

Wrap up your ImageView in a RelativeLayout with match_parent width and use
android:layout_alignParentRight="true"
like this:
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<ImageView
android:id="#+id/tri_logo"
android:layout_width="30dp"
android:layout_height="30dp"
android:layout_alignParentRight="true"
android:src="#drawable/tri_logo"/>
</RelativeLayout>

Use the tools a LinearLayout provides. Give weight to your child views and change the parent layout's gravity to right

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/toplayout"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:clickable="true"
android:orientation="vertical" >
<RelativeLayout
android:id="#+id/lout_profile_header"
android:layout_width="match_parent"
android:layout_height="100dp"
android:clickable="true"
android:gravity="center">
<com.test.customviews.CircleImageView
android:id="#+id/imgTopProfile"
android:layout_width="#dimen/profilie_icon_size"
android:layout_height="#dimen/profilie_icon_size"
android:layout_margin="#dimen/hdr_img_padding"
android:src="#mipmap/ic_profile" />
<TextView
android:id="#+id/textTopProfile"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_vertical"
android:layout_marginLeft="100dp" />
<ImageView
android:layout_alignParentRight="true"
android:id="#+id/tri_logo"
android:layout_width="30dp"
android:layout_height="30dp"
android:layout_gravity="right"
android:src="#drawable/tri_logo"/>
</RelativeLayout>
</LinearLayout>

Use RelatiVeLayout as immediate parent .
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/toplayout"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:clickable="true"
android:orientation="vertical" >
<RelativeLayout
android:id="#+id/lout_profile_header"
android:layout_width="match_parent"
android:layout_height="#dimen/top_view_height"
android:clickable="true"
>
<com.test.customviews.CircleImageView
android:id="#+id/imgTopProfile"
android:layout_width="#dimen/profilie_icon_size"
android:layout_height="#dimen/profilie_icon_size"
android:layout_centerVertical="true"
android:layout_margin="#dimen/hdr_img_padding"
android:src="#mipmap/ic_profile" />
<TextView
android:id="#+id/textTopProfile"
android:layout_width="match_parent"
android:layout_centerVertical="true"
android:layout_height="wrap_content"
android:gravity="center"
android:layout_toLeftOf="#+id/tri_logo"
android:layout_toRightOf="#+id/imgTopProfile"
android:layout_marginLeft="#dimen/hdr_name_padding" />
<ImageView
android:id="#+id/tri_logo"
android:layout_width="30dp"
android:layout_centerVertical="true"
android:layout_height="30dp"
android:layout_alignParentRight="true"
android:src="#drawable/tri_logo"/>
</RelativeLayout>
</LinearLayout>

Imageview not centered in parent - Android

I'm trying to position the blue icon precisely in the center of the card, but for some reason the icon goes up to the top of the card.
Can someone tell me what's wrong?
Thanks,
Here's a screenshot of my problem:
<GridView
android:id="#+id/documents_grid"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_marginTop="10dp"
android:columnWidth="#dimen/document_grid_item_width"
android:gravity="center"
android:horizontalSpacing="0dp"
android:numColumns="auto_fit"
android:stretchMode="spacingWidthUniform"
android:verticalSpacing="48dp" />
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="0.9"
android:focusable="true"
android:foreground="?android:selectableItemBackground"
android:background="#drawable/document_grid_item_bg">
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
<ImageView
android:id="#+id/draft_more_button"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentEnd="true"
android:layout_alignParentTop="true"
android:layout_marginTop="5dp"
app:srcCompat="#drawable/ic_more" />
<ImageView
android:id="#+id/imageView5"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
app:srcCompat="#drawable/draft_icon" />
</RelativeLayout>
</FrameLayout>
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_margin="5dp"
android:layout_weight="0.1">
<TextView
android:id="#+id/draft_date_tv"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:text="Date" />
</RelativeLayout>

I assume that in gridview item your parent is LinearLayout which can't be seen from your code snippet. If that's the case, in FrameLayout properties set the height to wrap_content
<FrameLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_weight="0.9"
android:focusable="true"
android:foreground="?android:selectableItemBackground"
android:background="#drawable/document_grid_item_bg">

Given code snippet is working fine with LinearLayout as parent.
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:orientation="vertical"
android:layout_height="wrap_content">
<FrameLayout
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="0.9"
android:focusable="true"
android:background="#color/colorGreen"
android:foreground="?android:selectableItemBackground">
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
<ImageView
android:id="#+id/draft_more_button"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentEnd="true"
android:layout_alignParentRight="true"
android:layout_alignParentTop="true"
android:layout_marginTop="5dp"
app:srcCompat="#drawable/ic_more" />
<ImageView
android:id="#+id/imageView5"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
app:srcCompat="#drawable/draft_icon"
android:layout_centerInParent="true" />
</RelativeLayout>
</FrameLayout>
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_margin="5dp"
android:layout_weight="0.1">
<TextView
android:id="#+id/draft_date_tv"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:text="Date" />
</RelativeLayout>
</LinearLayout>

1. Remove FrameLayout and add its attributes to child RelativeLayout.
2. Use attribute android:src instead of app:srcCompat to set image on ImageView.
Try this:
<?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">
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="0.9"
android:background="#fff">
<ImageView
android:id="#+id/draft_more_button"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentEnd="true"
android:layout_alignParentTop="true"
android:layout_marginTop="5dp"
android:layout_marginRight="5dp"
android:src="#drawable/ic_more" />
<ImageView
android:id="#+id/imageView5"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:src="#drawable/draft_icon" />
</RelativeLayout>
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_margin="5dp"
android:layout_weight="0.1">
<TextView
android:id="#+id/draft_date_tv"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:text="16 May 2017" />
</RelativeLayout>
</LinearLayout>
FYI, If you are using CardView as a container, then just put below LinearLayout inside your CardView.
OUTPUT:

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: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"

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"/>

How to overlay image in layout in android

I have two image in layout .I want to show second image in bottom edge curve of first image .Can anybody tell how to do like overlay image
Thanks

Use FrameLayout :
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<ImageView
android:id="#+id/imgFirst"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/ic_launcher"/>
<ImageView
android:id="#+id/imgSecond"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="bottom|center"
android:src="#drawable/ic_launcher"/>
</FrameLayout>

Use a RelativeLayout, simple put the second ImageView below the first ImageView. Then what you have to do is to set the marginTop attribute of the second image to a negative value, and this value is the overlaying size, like this android:layout_marginTop="-1dp".
A sample code right below:
<?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"
>
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/firstImage"
android:src="#drawable/myimage1"
/>
<ImageView
android:layout_width="wrap_content"
android:layout_marginTop="-1dp"
android:layout_height="wrap_content"
android:id="#+id/secondImage"
android:layout_below="#+id/firstImage"
android:src="#drawable/myimage2"
/>
</RelativeLayout>

You can do it without Frames, only using RelativeLayout, if you make use of the alignParentalXXX tags as in the following example
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#E4E3CE"
android:orientation="vertical">
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="75">
<ImageView
android:id="#+id/backgroundImageView"
android:layout_width="match_parent"
android:layout_height="300dp"
android:layout_alignParentTop="true"
android:layout_margin="5dp"
android:background="#ffffff" />
<ImageView
android:id="#+id/imageView"
android:layout_width="66dp"
android:layout_height="66dp"
android:layout_alignParentRight="true"
android:layout_alignParentTop="true"
android:layout_marginRight="10dp"
android:layout_marginTop="10dp"
android:background="#000000" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_alignParentTop="true"
android:layout_marginLeft="40dp"
android:layout_marginTop="20dp"
android:background="#40000000"
android:gravity="center_vertical"
android:paddingHorizontal="3dp"
android:paddingVertical="1dp"
android:text="Header Text"
android:textColor="#ffffff"
android:textSize="16dp" />
</RelativeLayout>
</LinearLayout>
You can see how this layout looks like in the following image:

Use Frame Layout like sample below :
<?xml version="1.0" encoding="utf-8"?>
