i want to create a button with green color background and a white line in center, like in the image.
If you want to use a 9 patch (name it btn_green.9.png - mind the extension!), put it in your /res/drawable-mdpi folder.
You can use this one:
This is how it is shown in the draw9patch tool:
This is how to add it:
<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="match_parent"
>
<ImageButton
android:layout_width="match_parent"
android:layout_height="96dp"
android:background="#drawable/btn_green"
/>
</RelativeLayout>
It only uses 1 View, so it's a superfast (the less Views, the better performances)!!
You can create an ImageButton with Background attribute, and then create a View for the line setting the margin attribute to move it the position you want.
This is a very fast xml, but you can start playing with it
<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="match_parent">
<ImageButton
android:layout_width="fill_parent"
android:layout_height="100dp"
android:background="#009900" />
<View
android:layout_width="fill_parent"
android:layout_height="5dp"
android:layout_marginTop="50dp"
android:background="#FFFFFF" /> </RelativeLayout>
If you want to make the button like that, you can use FrameLayout.
<FrameLayout 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">
<ImageButton
android:layout_width="fill_parent"
android:layout_height="100dp"
android:background="#009900" />
<View
android:layout_width="fill_parent"
android:layout_height="2dp"
android:layout_gravity="center_vertical"
android:background="#FFFFFF" />
</FrameLayout>
The reason why i'm using FrameLayout is to overlap Views. so try this code, i hope it works.

I mean how can i locate a ImageView in two layouts? i have 2 relative layouts one is up, one is down. The up one has a ImageView but i want half of this ImageView located in down layout. How can i do that?
EDIT::
Try this:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/main_container"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_margin="#dimen/activity_horizontal_margin"
android:background="#d2aff4">
<Space
android:id="#+id/center"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_centerInParent="true" />
<RelativeLayout
android:id="#+id/bottom"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_below="#id/center"
android:background="#87c96d" />
<RelativeLayout
android:id="#+id/top"
android:layout_width="match_parent"
android:layout_height="match_parent">
<ImageView
android:layout_width="150dp"
android:layout_height="150dp"
android:layout_centerInParent="true"
android:src="#mipmap/ic_launcher" />
</RelativeLayout>
</RelativeLayout>
In this scenario the "top" layout needs to be created at last to be displayed on top of the rest of the views. If you need it to have a background colour, you need to apply the colour to the main container.
Here is the result:
I agree with #Booger answer's but If your parent layout is RelativeLayout then add this below property in you ImageView.
android:layout_centerInParent="true"
Or you can use below code to create that kind of layout
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:background="#color/white"
android:orientation="vertical">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1"
android:background="#color/gray_font">
</LinearLayout>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1"
android:background="#color/colorAccent">
</LinearLayout>
</LinearLayout>
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#mipmap/ic_launcher"
android:layout_centerInParent="true"/>
</RelativeLayout>
Take a look at this library https://github.com/umano/AndroidSlidingUpPanel
if you want something easy you can put those layouts in to a parent relative layout and then you can add a image view in parent relative layout as last child and position it how you need
I think you should wrap both your RelativeLayout in another Parent layout, and in that layout, you will place your ImageView (which will span both the other layouts.
Something like this pseudo-code:
<LinearLayout>
<RelativeLayout1>
<RelativeLayout2>
<ImageView gravity=center> //Order counts, this needs to be after the RelativeLayouts to show on top of them
</LinearLayout>
I need to display an image and text on a single row. The image should resize based on the text height. I know that it's possible programmatically but is it possible to do this also only in XML ?
<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="match_parent">
<ImageView android:id="#+id/Image" ... />
<TextView
android:id="#+id/Text"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_above="#id/Image"
tools:layout_editor_absoluteX="47dp"
tools:layout_editor_absoluteY="37dp" />
</RelativeLayout>
Just wrap the views inside a parent view that adjust to the textview and make the imageview resize according to the parent.
<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="match_parent">
<!-- LOOK HERE-->
<LinearLayout
android:orientation="horizontal"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<TextView
android:id="#+id/Text"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_above="#id/Image"
tools:layout_editor_absoluteX="47dp"
tools:layout_editor_absoluteY="37dp" />
<ImageView android:id="#+id/Image"
android:layout_heigth="match_parent"
android:layout_width="wrap_content" />
</LinearLayout>
</RelativeLayout>
I haven't test it, but it should be something really close to this.
EDIT: Using an horizontal LinearLayout should give you a quick view of how is working and the in the linear layout you arrange with the toRightOf, toLeftOf, etc.
I have the following layout (here is presented much simpler design):
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="#string/appbar_scrolling_view_behavior"
tools:showIn="#layout/activity_main">
<FrameLayout
android:orientation="horizontal"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:layout_alignParentEnd="true"
>
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Hey, badge!"
android:layout_margin="10dp"
/>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="AAAAA"
android:layout_margin="10dp"
android:textSize="12sp"
android:background="#ff00ff"
android:padding="10dp"
android:layout_gravity="top|end"
/>
</FrameLayout>
</RelativeLayout>
I wish to set TextView with text "AAAA" to act as a badge for Button, i.e. to be placed over the button in its upper right corner, which is not the case.
Instead, when I try this code on HTC One M7 with Lollipop, or on Genymotion Nexus 6 with Lollipop, screen looks something like this:
When I try the same code on Genymotion Nexus 5 with KitKat, everything looks as expected, i.e. first view (button) is shown underneath badge (textview)
Does anyone have any clue what could be wrong here?
Thanks,
Deveti
The elevation causes this issue. It was introduced in Lollipop and responsible for z-ordering too. Copy your layout to layout-v21 and set android:elevation="0dp" for the button.
I saw this on another thread somewhere but you can put this into your elements :
android:stateListAnimator="#null"
as others said the button elevation in lolipop and up is changed so its covering the other elements.
for example in my button view below i use it and it shows:
<FrameLayout
android:id="#+id/ib_one_container"
android:layout_width="38dp"
android:layout_height="38dp"
android:layout_marginLeft="5.3dp"
android:orientation="vertical"
android:padding="3dp"
>
<Button
android:id="#+id/ib"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#color/white"
android:clickable="true"
android:gravity="center"
android:stateListAnimator="#null"
android:textSize="11sp" />
<com.mobile.pomelo.UI.customViews.CustomDiagonalLineView
android:id="#+id/diagaonal"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:visibility="visible"
/>
</FrameLayout>
I had a similar problem with an FrameLayout that I was using as a progress indicator overlay (when my screen is busy loading).
I didn't want to add XML to every other element in my app, so I just added an elevation to to my FrameLayout overlay. Note the clickable attribute which ensures that click events are not passed down to the buttons underneath.
Progress Indicator overlay:
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/progress_overlay"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:alpha="0.4"
android:background="#android:color/black"
android:animateLayoutChanges="true"
android:elevation="10dp"
android:clickable="true"
android:visibility="gone">
<ProgressBar
style="?android:attr/progressBarStyleLarge"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:indeterminate="true"/>
</FrameLayout>
Including the progress indicator in my other views:
<include layout="#layout/progress_overlay"/>

I make a xml file for android interface. In this xml, there's an expendable items. I want to add background for this xml with tansparency (alpha) but when i add bacground in relative layout with alpha like this
<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="match_parent"
android:background="#drawable/background"
android:alpha="0.2"
tools:context=".ListGestureActivity" >
that will make background transparency become black not white. In other xml happened like that too.
But in other xml i tried to do this
<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="match_parent"
android:background="#color/white"
tools:context=".HintGestureActivity" >
<ImageView
android:id="#+id/imageView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_alignParentTop="true"
android:layout_alignParentRight="true"
android:layout_alignParentBottom="true"
android:alpha="0.3"
android:background="#drawable/background"
/>
it worked. But in xml with expendable items didn't work.
Do you any suggestion?
U can do something like this
android:background="#00564678"
For Ex:
<ImageView
android:id="#+id/imageView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_alignParentTop="true"
android:layout_alignParentRight="true"
android:layout_alignParentBottom="true"
android:alpha="0.3"
android:background="#00564678"
/>
By default it takes black color as your background color and after that, if you apply transparency then you will not get desired output.Therefore, first you need to set some background color after that apply alpha on that. Try this :
<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="match_parent"
android:background="#color/white"
android:alpha="0.2"
tools:context=".ListGestureActivity" >
the imageview takes extra [black] space and i dont know why
ok this imageview should wrap content but instead..
photo explains the problem
this is the code
<?xml version="1.0" encoding="utf-8"?>
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical" >
<ImageView
android:id="#+id/map"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/map" /><ImageView
android:id="#+id/blxx"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:paddingBottom="-20dp"
android:src="#drawable/photo" />
<ImageView
android:id="#+id/blxx"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:src="#drawable/blxx" />
</LinearLayout>
</ScrollView>
Try the below:
android:adjustViewBounds="true"
This will remove the extra padded space
first possible reason for your problem:
sometimes when the image is too small, it can't scratch anymore then some limit. after that limit - what happens is what you see - blank space claimed by the imageView where additional scratch of the image was expected. I advice you to take larger picture (with bigger resolution)
Second possible reason:
add to your imageView properties on the xml file the following attribute:
android:scaleType="fitXY"
android:layout_gravity="center"
Above line is centering the image to fit inside your ImageView. Try without it. If not, set gravity to "fill" and try again.
Also remove one of the duplicates of blxx as noted.
hope this ll help you
