I want to acheive the following. Transparent background with white tick
How do i get the white tick mark on the transparent background.
i tried the following.
viewprev = mgridview.getChildAt(i - mgridview.getFirstVisiblePosition());
viewprev.setBackgroundColor(Color.WHITE);
viewprev.setAlpha(0.5f);
Try this out,
<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout 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">
<ImageView
android:id="#+id/ivMain"
android:layout_width="200dp"
android:layout_height="200dp"
android:contentDescription="#string/app_name"
android:src="#mipmap/ic_launcher"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent" />
<FrameLayout
android:layout_width="150dp"
android:layout_height="150dp"
android:background="#99676767"
app:layout_constraintBottom_toBottomOf="#id/ivMain"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="#id/ivMain">
<ImageView
android:layout_width="55dp"
android:layout_height="55dp"
android:layout_gravity="center"
android:contentDescription="#string/app_name"
android:src="#drawable/vector_favorite" />
</FrameLayout>
Your tick should be in the FrameLayout which should be constrainted as in the code so its always in the middle of the ImageView. From the image I guess you're trying to create a long click to select items kind of thing. If so just set the visibility of FrameLayout to gone in xml and in LongClick event set it to visible
This is the output of above code:
You can play around with the color to achieve your desired transparency level
You may need to use FrameLayout.The Framelayout contains your image and an empty ImageView above it. When you need to draw a tick - just set its image into that ImageView.
First you need to add an ImageView to your grid item layout. Remember to insert the xml tag below the main grid image in order to appear on top. Then use match_parent as the image view width and height and assign the scaleType to center. This is your check mark view. You can add a semi transparent background to make a shade above the grid item image and the src attribute goes to the check mark.
You can also modify the image view visibility toggle hide and show of the check mark item.

I have a circular image and a button icon
Lets say image is size of 20x
And button is size of 8x
I want to put the button icon in a way that 80% of its portion stays on the image view and 20% goes beyond it.
My xml code-
RelativeLyaout<
andoird.cardview.widget.Cardview<
<ImageView/>
/>
<button_icon>
layout_alignRight:ImageView
</button_icon>
ImageViw and button_icon overlaps but not that way I want.
80% portion of the button stays behind the image view that i cant see and the rest 20% of the button that goes beyond the image view is visible
This is for my Android studio app. I things above code is less time consuming.
If you need full code i can provide that too.
you can't exceed parents bounds. but you can introduce one extra layer which will hold both your Views and second one may cover part of first one. some basic example with FrameLayout
<FrameLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
<View
android:layout_width="100dp"
android:layout_height="100dp"
android:background="#097267">
<View
android:layout_width="80dp"
android:layout_height="80dp"
android:layout_margin="40dp"
android:background="#A9C26A">
</FrameLayout>
also be aware that elevation and translationZ XML attributes may change order of drawing (first View will be drawn on top of second and will cover it). e.g. Button have some elevation set by default, also CardView (setCardElevation(float)) - additionally (mainly?) this makes some small shadow under these Views
Try this code... I have added constraint layout and inside it i have added button overlapping the image.
You can change the size according to your requirements !!

I'm using Glide library for downloading images and displaying them in my adapter, the problem is, after it sets the images, they get a background that is not in the downloaded image, the ImageView added this color to them
this is an example:
as you can see it has a very light green background color, the image it self has white background.
things I've tried so far:
set white background color in my xml layout
set transparent background color
used View.setBackgroundColor(Color.TRANSPARENT) in my adapter
used View.setBackgroundColor(0x00000000) in adapter
nothing worked...
how can I get rid of it?

the layout file attached :
<?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:id="#+id/flag"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_centerInParent="true"
android:adjustViewBounds="true"
android:backgroundTint="#fff"
android:background="#fff" />
</RelativeLayout>
Look at the image, which has a white background. Try to add a transparent image and your problem will be solved. I removed the background of that image. Look at the difference between these two images.
Hello I am working with android.I have a custom imageview.I want to hide partial imageview behind the screen. I tried padding=-100... etc. But its not working .How can I hide a view partially behind screen ?
use negative margin to parent layout like this, its working
<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"

You need to create your view through java or make a drawable of semicircle and set it as background of imageview.
Refer this: Semicircle drawable
I have two images - 1)a rectangular one, displaying the actual content and 2)a white image with rounded transparent corners
Is it possible to place image 1 inside image 2, keeping its size but making it to be the same shape as 2?
Basically I want Image 2 be the container of image 1.
I've tried layer and inset drawables but all the time image 1 overlapped image 2.
Thanks in advance!
UPDATE 1:
Here's my ImageView xml part:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="72dp"
android:orientation="horizontal">
<ImageView
android:id="#+id/avatar"
android:src="#drawable/mainImg"
android:background="#drawable/backgroundImg"
android:layout_width="56dp"
android:layout_height="56dp"
android:layout_gravity="center"
android:contentDescription="#string/desc" />
</LinearLayout>
UPDATE 2:
Below is the link to three images
1) background
2) main image
3) expected result (with rounded corners)

I have had to deal with this issue with an app I recently made. Notice how, in the first and second screenshot, the thumbnails are all framed.
To accomplish this, I'm stacking the image and the frame on top of each other in a FrameLayout. First I layout the actual image (#id/thumbnail), followed by the frame (#id/frame).
Important things to note are that the thumbnail is using a scaleType of "fitXY", and has a slight margin so the corners don't stick out behind the frame's rounded corners.
This really only works if your frame border is opaque, so you may have to make your frame edges the same color as your background.
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="#dimen/thumbnail_size"
android:layout_height="#dimen/thumbnail_size"
android:layout_margin="5dp"
android:gravity="center"
android:orientation="vertical"
>
<ImageView
android:id="#+id/thumbnail"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_gravity="center"
android:layout_margin="4dp"
android:scaleType="fitXY" />
<ImageView
android:id="#+id/frame"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#drawable/pixel_frame"
android:scaleType="fitXY" />
</FrameLayout>
One easy solution would be to use just one ImageView with android:background for your image2, which you say is the container, andr android:src for image1, which is the actual image :
<ImageView
...
android:background="#drawable/image2"
android:src="#drawable/image1"
android:padding="2dp" />
Just add a padding, to specify how much empty space you want to leave between the "frame" and your actual "picture".
Use ImageButton.. Set Background as Image1 and Image src as Image2
<ImageButton
android:id="#+id/imageButton1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#drawable/image2"
android:src="#drawable/image1" />
This is my Android list_item layout XML:
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="fill_parent"
android:paddingRight="?android:attr/scrollbarSize"
android:background="#drawable/list_bg">
<TextView
android:id="#+id/tv_displayname"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:ellipsize="end"
android:textAppearance="?android:attr/textAppearanceLarge" />
</RelativeLayout>
This is the list_bg image:
and yet here is what it looks like when shown in Android emulator:
I can see that the background is being applied because there is a slight gradient effect to it, but I have no idea where this black overlay is coming from!
have you tried a different image to see if that one does the same thing? to me it looks like it is creating the image behind the list in your RelativeLayout and your textview background is on top. since you are setting it to fill the width of the row, i bet if you just set to wrap_content you would see it behind there
try putting the image as your TextView background instead
