How to use transparent text on image in android - android

Recently I have seen an apps, which has an image with text.
Whether the app used ImageView and TextView? How does the text overlay the image? How has it been done?
I have attached the screenshot.

Set the attribute android:background="#00000000" on your TextView in the layout. XML file.
<FrameLayout
android:layout_height="wrap_content"
android:layout_width="match_parent"
>
<ImageView
android:src="#drawable/your_image"
android:layout_height="match_parent"
android:layout_width="match_parent"
/>
<TextView
android:height="match_parent"
android:width="match_parent"
android:background="#00000000"
android:gravity="bottom"
/>
</FrameLayout>

you can either use FrameLayout to put TextView on ImageView or
You can take a text view with the background resouce as your image , something like this
Example:
<TextView
android:layout_gravity="center"
android:background="#drawable/custom_buttonclick"
android:gravity="center"
android:textSize="12dp"
android:textStyle="bold" />

By using Relative Layout, ImageView and TextView you can achieve this put background color of textView to transperent.

ImageView overlay not working

I have 2 layouts in my xml, a CircularImageView and a ImageView, and the ImageView must appear on top of the CircularImageView.
I've tried:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/fragment_kids_register_ll_kid"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#color/md_white_1000"
android:orientation="horizontal">
<RelativeLayout
android:padding="16dp"
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<com.mikhaellopez.circularimageview.CircularImageView
android:id="#+id/fragment_kids_row_img_kids"
android:layout_width="70dp"
android:layout_height="70dp"
android:src="#drawable/ic_boy"
/>
<ImageView
android:id="#+id/fragment_kids_row_iv_crown"
android:layout_toRightOf="#+id/fragment_kids_row_img_kids"
android:layout_marginLeft="-26dp"
android:layout_marginTop="-22dp"
android:layout_width="48dp"
android:layout_height="48dp"
android:src="#drawable/ic_crown"/>
</RelativeLayout>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<TextView
android:id="#+id/fragment_kids_row_tv_name"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="20dp"
android:textColor="#color/md_black_1000"
android:textSize="24sp" />
<TextView
android:id="#+id/fragment_kids_row_tv_age"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="10dp"
android:text="1 ano e 4 meses"
android:textColor="#808080"
android:textSize="12sp" />
</LinearLayout>
</LinearLayout>
And it is getting cut off:
I need the image to be shown exactly at that position in the picture, but not "cropped", what I am missing here ?
BTW, this component is part of a RecyclerView row.
EDIT ---
I forgot to mention, the image is just a placeholder to show the Avatar, but the image is dinamically populated !
Thanks !
The padding (16dp) that you are applying to the first relativeLayout makes you think that there is more place and that you can move up the imageView. Actually the margin is like a gap, it doesn't extend your layout.
This is the solution I suggest , using a FrameLayout
<FrameLayout
android:layout_width="100dp"
android:layout_height="100dp">
<com.mikhaellopez.circularimageview.CircularImageView
android:id="#+id/fragment_kids_row_img_kids"
android:layout_gravity = "center"
android:layout_width="70dp"
android:layout_height="70dp"
android:src="#drawable/ic_boy"
/>
<ImageView
android:id="#+id/fragment_kids_row_iv_crown"
android:layout_width="48dp"
android:layout_height="48dp"
android:src="#drawable/ic_crown"
android:layout_gravity="right|top" />
</FrameLayout>
EDIT : You don't have to use a frameLayout, you can use a relativeLayout if you want to set different margins. The point here is really to make your containing layout bigger so you can place the imageview easily.
If you want one image to be on top of another, why you use android:layout_toRightOf?
Remove it and second image should cover first one.
Also you can try to remove margins at second image and use centerInParent, centerVertically or centerHorizontally.
Or maybe I didn't got all the problem ) then pls provide more details. Thanks.
Have you tried Using an image editor like Paint/Photoshop and merging the two images? Then you can just display one image in your view.
try using a linear layout with the orientation set to vertical.

I want to put image over button

I want to put png image over button i tried android:background but the png takes all the button what i want exactly is to use the logo png over button like this
the info logo is my png and "about" comes from the button text
u can use this:
android:drawableTop="#drawable/SomeIcon"
so then you get this:
<Button
android:id="#+id/damage"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal"
android:text="about"
android:drawableTop="#android:drawable/ic_menu_info_details"/>
it works for me :)
You can use a FrameLayout. In a FrameLayout, the z-index is defined by the order in which the items are added, for example
<FrameLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content">
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/button_text" />
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/my_drawable"
android:scaleType="fitCenter"/>
</FrameLayout>
In this instance, the ImageView would be drawn on top of the Button, along the bottom center of the Button.
You can check this thread
Basically, you can use:
<ImageButton
android:id="#+id/ImageButton01"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/album_icon"
android:background="#drawable/round_button" />
As the thread says.
Take a RelativeLayout, place ImageView inside it. Now set onClickListener on RelativeLayout.
By this way you can create more complex buttons.
<RelativeLayout android:id="#+id/your_btn_id"
android:layout_width="match_parent"
android:layout_height="wrap_content" >
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true" />
</RelativeLayout>
you can use
android:drawableTop
to put drawable at top of Button and use appropriate padding to make it position well.
<Buttton
android:layout_width="99dp"
android:layout_height="99dp"
android:background = "#drawable/bg" />
bg is your custom image.

How to put a TextView in the center of a ImageButton?

Say I have an ImageButton. I want a textview on top of the imagebutton, and centered on it. How would I do this?
you could do it by wrapping both widgets in a FrameLayout
for example:
<FrameLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content" >
<ImageButton
android:layout_width="match_parent"
android:layout_height="match_parent"
android:src="#drawable/image" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/text"
android:layout_gravity="center" />
</FrameLayout>
Use a regular Button, which extends TextView anyway. Then set the background to your image and use setText() to set your text. You can even add icons above, below and/or left & right of the text with the drawableLeft,drawableTop,etc attributes.
You Are overcomplicating your layout. Just add text to the button.
myImageButton.setText("text");
If you really do want to layer these views, you should use a RelativeLayout:
<RealtiveLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
<ImageButton
android:layout_width="match_parent"
android:layout_height="match_parent"
android:src="#drawable/img"/>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/app_name"
android:layout_centerInParent="true"/>
</RelativeLayout>
Make a special note of the attribute layout_centerInParent . this is how the TextView is correctly centered.

Placing text view over an image view using FrameLayout

Below is how I have designed my xml. Now what I am trying to fit a textview inside the white box shown below. But am being restricted by FrameLayout (at least I think so) that I need to hard code values to make the text view fit in the middle or some where inside the white box. I cannot use Relative or other layouts for this purpose as I have understood by my trials as this whole is a single image.
Here is my layout,
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content" android:layout_height="wrap_content"
android:visibility="visible" android:layout_marginTop="60dip"
android:layout_gravity="center" android:id="#+id/xxx">
<ImageView android:id="#+id/calloutquizImage"
android:background="#drawable/callout" android:layout_width="wrap_content"
android:layout_height="wrap_content" android:scaleType="fitCenter" />
<ImageView android:id="#+id/triviaImage"
android:layout_width="wrap_content" android:layout_height="wrap_content"
android:layout_alignTop="#+id/calloutquizImage" android:layout_gravity="left"
android:src="#drawable/trivia" android:background="#drawable/trivia"
android:layout_marginTop="50dip" android:layout_marginLeft="85dip"></ImageView>
<TextView android:text="TextView" android:id="#+id/triviAnswerText"
android:layout_marginTop="125dip" android:layout_marginLeft="85dip"
android:layout_gravity="left" android:layout_width="wrap_content"
android:layout_height="wrap_content" android:textColor="#000000"
android:typeface="sans"></TextView>
<ImageButton android:id="#+id/triviaanswercloseButton"
android:src="#drawable/closebtn" android:layout_width="wrap_content"
android:layout_height="wrap_content" android:background="#drawable/closebtn"
android:layout_marginRight="8dip" android:layout_marginTop="43dip"
android:layout_gravity="right" android:onClick="triviaanswerClose"></ImageButton>
<ImageView android:id="#+id/buttontoclose"
android:layout_gravity="left"
android:visibility="visible" android:onClick="triviaanswerClose"
android:layout_marginTop="50dip" android:layout_marginLeft="75dip"
android:layout_width="230dip" android:layout_height="170dip"></ImageView>
</FrameLayout>
Because of this the text view looks in different positions in various handsets.
Any guesses what can be done for this instead?
Below is my image :
I think you are not doing the right thing. If you want a text to appear inside a white box (or even resize it, if there is to many text to fit to it) - you can still avoid any layouts ad do it with only one TextView.
Please have a look what is NinePatch image in Android:
http://developer.android.com/reference/android/graphics/NinePatch.html
http://developer.android.com/tools/help/draw9patch.html - drawing tools
So basically you will need only 1 textView and your image, properly converted to 9-patch with 2nd link. (Basically - just add a few black pixels on image border).
No just set this 9-patch as a background of textView. It will place text right where you need, and will shrink white box if you'll define so in 9-patch.
UPD:
Please find the resulting screenshot:
As you can see, textView not handles
WhiteBox" itself, filling it with text and resizing the box if necessary.
Here is how to make it work:
<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">
<TextView
android:id="#+id/first"
android:background="#drawable/back"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Manymanymany text
Manymanymany text
Manymanymany text
Manymanymany text
Manymanymany text
Manymanymany text" />
<TextView
android:layout_below="#+id/first"
android:background="#drawable/back"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Not so many text" />
</RelativeLayout>
And here is your image, converted to 9patch. Just place it to "drawable/" folder. Note: it MUST have "back.9.png" name.
For details of how 9patch works you can check links above. The main idea: by making black dots on left and top border - you specify which part of the image will be stretched when image must be upscaled. By making dots on right/bottom side you tell the View where to place the content. In our case content is a text of the TextView.
Hope it helps, good luck
I think you can use a RelativeLayout within the FrameLayout for the ImageView and the TextView, and by using the parameters, you can navigate the TextView to the white box. Refer to the LayoutParams documentation for details.
for eg. you can add the ImageView block first and then the TextView, so that the TextView will lay over the ImageView, and by using align bottom, and specifying top margin with a negative value, you can make the TextView go over the image. Or rather, if you are using eclipse, you can directly move the text view in the graphic layout.
<FrameLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/tools"
android:id="#+id/xxx"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:layout_marginTop="0dp"
android:visibility="visible" >
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_margintop="0dp" >
<ImageView
android:id="#+id/imageView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/user2" />
<TextView
android:id="#+id/Textviewtitle"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/hello_world"
android:layout_below="#+id/imageView1"
android:layout_marginTop="-10dp"
app:context=".TestActivity" />
</RelativeLayout>
</FrameLayout>
Similar to above, you can specify margin left and right to properly position your TextView as you want. Check with graphic layout for feedback to know the correct position.
Please reply if this helped.
Use your images and values for the height and width. I just tried for testing.

Transparent TextView background in FrameLayout

I placed a TextView on an ImageView in a FrameLayout. I've tried various combinations of android:background for the TextView but always get a see-through grey background on it. I'd like a transparent background. The android:background attribute seems to be ignored.
<HorizontalScrollView
android:id="#+id/categories_horizontal_scrollview"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:paddingBottom="25dip">
<LinearLayout
android:id="#+id/categories_linear_layout"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<FrameLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<ImageView
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:id="#+id/photos_imageview"
android:scaleType="center"
android:src="#drawable/photos_ipad" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/photos_text"
android:layout_marginBottom="10dip"
android:layout_gravity="center_horizontal|bottom"
android:padding="3dip"
android:background="#00000000"
android:textColor="#ffffffff"
android:textSize="20dip"
/>
</FrameLayout>
.
.
Use this:
TextView tv;
tv.setBackgroundColor(0xXX??????);
Where XX - [00;FF] - indicator of trancparecy. ?????? - Some numbers (raw color)
Hope it helped)))
As Brayden pointed out, there was a problem in the layout. I ended up putting the ImageView and TextView into a FrameLayout as a single resource, then adding that dynamically where needed.
We use like this code for transparent background.
android:background="#android:color/transparent"
