The images shown below are in PNG format, with transparent background.
I used a TextView per item which consists of a DrawableTop image and Text. I wanted my image to be transparent but it is not working properly. I tried alpha method for transparency but the entire TextView will lighten. I wanted just the image, not the entire TextView.
By the way, I used TextView instead of a LinearLayout per item consisting of an ImageView and TextView because the IDE prompted me with a warning and I was advised not to have any warning in my code.
I have the following code in Android:
<TextView
android:id="#+id/marketBtn"
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_gravity="bottom"
android:layout_weight="1"
android:background="#drawable/unselected_button"
android:drawableTop="#drawable/market_icon_0"
android:gravity="center"
android:paddingBottom="5dp"
android:paddingLeft="1dp"
android:paddingRight="1dp"
android:paddingTop="5dp"
android:text="#string/task_bar_lbl_market"
android:textAppearance="?android:attr/textAppearanceSmall"
android:textColor="#FFFFFF"
android:textSize="13sp" />
I am now confused what to do next. Should there be any help, I will be much grateful! For more info, here's a screen cap of this bug:
Use Button instead of TextView :
<Button
android:id="#+id/marketBtn"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_above="#+id/show"
android:layout_alignLeft="#+id/name"
android:layout_marginBottom="36dp"
android:background="#drawable/unselected_button"
android:drawableTop="#drawable/market_icon_0"
android:text="#string/task_bar_lbl_market"
android:textColor="#FFFFFF"
android:textStyle="bold" />
You must combine background and drawableTop style.
You don't need image transparent for background.
You can used #ARGB [int alpha, int red, int green, int blue]
<item name="android:background">#0000</item>
<item name="android:drawableTop">#drawable/btn_setting</item>

I have this textview which is white in color and I am putting on top of an image with lighter background. The problem is that the text "My App" is barely visible. Is it the contrast or what do I have to change on textview to stand the bright white color out? If the background color of image is dark then the white color stand out but in this case it almost blends.
<android.support.design.widget.CoordinatorLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:background="#drawable/skyline"
tools:context=".SplashActivity">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="#dimen/size_75dp"
android:text="My App"
android:textColor="#FFFFFF"
android:textSize="60sp"
android:layout_gravity="center_horizontal|top" />
</android.support.design.widget.CoordinatorLayout>
Add a translucent background to your TextView
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="#dimen/size_75dp"
android:text="My App"
android:textColor="#FFFFFF"
android:background="#30000000"
android:paddingLeft="16dp"
android:paddingRight="16dp"
android:textSize="60sp"
android:layout_gravity="center_horizontal|top" />
Edit: based on your comment, look at the Palette library.
If I were in your situation, I'll try to tackle the issue by handling both image and text, since we might have a bright background with a white text or vice Versa.
First, we'll make sure our image background is dark enough to let our white textView visible clearly, I recommend to apply a light overlay upon the imageview (Framelayout with top image) or even use the alpha attribute.
Now that our image is arranged, we should do the same for the textview but this time using shadows, like the following
android:shadowColor="#000000#"
android:shadowDx="0"
android:shadowDy="2"
android:shadowRadius="20"
Change the above values according to your needs.
Hope that answers your question.
I created a personal keyboard and set the background image to the one of the buttons, but after that button size (with my background) is different from one another.
<Button
android:id="#+id/buttonShift"
android:paddingTop="0dip"
android:textSize="22sp"
android:layout_height="match_parent"
android:layout_width="0dp"
android:layout_weight="1"
android:textStyle="bold" />
Set background:
<Button
android:id="#+id/buttonShift"
android:background="#drawable/sym_keyboard_shift_off"
android:paddingTop="0dip"
android:textSize="22sp"
android:layout_height="match_parent"
android:layout_width="0dp"
android:layout_weight="1"
android:textStyle="bold" />
Please, see the screen of the buttons
Before:
After:
Image size: 106x68
I would advise you to:
Change your drawable a bit - remove the orange rectangle background, keep only the arrow with transparent background (from now on I will use the name shift_off_arrow as a name of described drawable). The transparent background should be only as big as it is needed to keep the whole arrow. Not bigger.
Define a new color - the color of your orange background (from this moment I will assume you have defined it and I will be using name orange_background)
Use ImageButton instead of Button (just like satnam singh and Hamid Shatu said in a comments to your question)
Use code like this (manipulate with all paddings to get the size of the arrow exactly like you want):
<ImageButton
android:id="#+id/buttonShift"
android:background="#color/orange_background"
android:src="#drawable/shift_off_arrow"
android:paddingTop="0dip"
android:layout_height="match_parent"
android:layout_width="0dp"
android:layout_weight="1" />
For some reason, I need to use a button with both icon and text. So I can't use ImageButton and thus I go for a solution to set the drawableTop of a normal Button.
The Button size is 140dp in square shape (please refer to the screenshot below)
The I was planning to use was 125x125 px and the asset itself is clear and crisp.
However, this 125px asset somehow being enlarged by the button, like the screenshot shown below.
The device is an xhdpi device.
As you can see, the icon inside the square button is blurry which looks like being somehow enlarged
Here I pasted my button XML
<Button
android:id="#+id/button_call_us"
android:layout_width="140dp"
android:layout_height="140dp"
android:layout_margin="#dimen/main_menu_button_margin"
android:adjustViewBounds="true"
android:background="#drawable/custom_button"
android:drawablePadding="-20dp"
android:drawableTop="#drawable/button_call_us_icon"
android:lines="2"
android:paddingTop="0dp"
android:scaleType="fitXY"
android:text="CALL US"
android:textColor="#color/white"
android:textSize="6pt" />
The android:background="#drawable/custom_button" is the purple colour background without any patterns.
The android:drawableTop="#drawable/button_call_us_icon" is the icon.
Except android:scaleType="fitXY", I have also tried centerInside and other options, still not getting the ideal result.
My question is:
Why the drawable inside a Button being enlarged? Is there any way to stop it?
Thanks
Since it's a button, and you want a drawable inside the button. Your probable solution would be to use an ImageButton which actually implements drawable properties. You can then call android:scaleType="fitCenter" and set some padding too
<ImageButton
android:id="#+id/imageButton1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/android_button" />
However, to get more freedom in terms of desing, you could use a simple layout instead of the button, something on the lines of this, just treat the LinearLayout as you would with a button, in terms of adding the onclicklistener:
<LinearLayout android:orientations="vertical"
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:orientation="vertical"
android:background="#CCC"
android:padding="8dp"
android:gravity="center">
<ImageView android:src='#drawable/ic_launcher'
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
<TextView android:text="Lorem Ipsum"
android:layout_height="wrap_content"
android:layout_width="wrap_content" />
</LinearLayout>
Try this code
Drawable img = getResources().getDrawable( R.drawable.img );
img.setBounds( 0, 0, (int)(img.getIntrinsicWidth()),
(int)(img.getIntrinsicHeight()) );
button.setCompoundDrawables(null, img, null, null);
I searched a lot but I didn't find how to remove the background color from the button which is appearing on the right and left side of button. Can anybody help?
My screen looks like
No matter what I try I am not able to remove the black portion.
Code:
<LinearLayout
android:orientation="horizontal"
android:layout_width="match_parent"
android:layout_height="wrap_content" >

this is the image used with name change.9.png
according to your scenario i can surely say that either you are not using a 9-patch image (an image with extension like .9.png ) or the 1 pixel borders of 9-patch at left and top are not drawn in correct manner. thats why the edges and the side border shade get expanded with the button with long width. either you should show what 9-patch button background you have used or try some correct 9-patch and check results for that.
Why don't you use some other control element like TextView instead of buttons? I just saw that TextView has onClickListner and so you can use it as sort-of button, though I have not done it; button is meant to aid you defining your layout, but as this seems to only be a problem for you, just do not use it).
By the way I seriously recommend you to use android styles, as you copy-paste a lot of attributes. If you use Eclipse for development, open your layout xml, select the item you want to extract the style of, press ctrl + 1 and then select extract style. That way you should avoid copy-pasting all these style attributes.
Try removing the android:textColor attribute. These can be misleading and sometimes alter the colour of more than just the text. If the text is supposed to be black then you don't need it.
I have a TextView with a background that declared as:
<TextView
android:id="#+id/questionText"
android:layout_width="250dp"
android:layout_height="100dp"
android:gravity="center"
android:textSize="26px"
android:textColor="#FFFFFF"
android:background="#drawable/blue"
/>
the problem is that the background image is like a frame, so i want the
text inside to have a margin from the background image dimensions.
Is this possible?
10X alot,
have a gr8 weekend :)
What you want sounds like padding.
<TextView
android:id="#+id/questionText"
android:layout_width="250dp"
android:layout_height="100dp"
android:gravity="center"
android:textSize="26px"
android:textColor="#FFFFFF"
android:background="#drawable/blue"
android:padding="5dp"
/>
This would put a 5 pixel border around the actual text showing the background through.
Incidentally, layout_margin is also a parameter and is used to put space between the entire view, background included, and other views.
I'd recommend to make 9-patch drawable. It defines where the text can be without specifying padding in the control.
