Simply, how to make a TextView transparent? (Not full transparency)
I searched the docs and the StackNetwork and couldn't find it? I guess there is something like this.
Thanks.
UPDATE
This is the XML code:
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:gravity="center_horizontal"
android:orientation="vertical"
android:background="@drawable/background">
<ImageView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:id="@+id/header"
android:src="@drawable/logo1"
/>
<ListView android:id="@android:id/list"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_weight="1"
android:paddingRight="5dp"
android:scrollbarStyle="outsideOverlay"
android:cacheColorHint="#00000000" />
<TextView
android:id="@+id/footer"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textSize="25sp"
android:singleLine="true"
android:background="#07000000"
android:textColor="#FFFFFF"
android:text="rrrrr" />
</LinearLayout>
I want the footer TextView
to be transparent so that the ListView items can be seen while scrolling
This question is related to
android
transparency
transparent
textview
Use this:
android:background="@android:color/transparent"
To set programmatically:
setBackgroundColor(Color.TRANSPARENT);
For me, I also had to set it to Color.TRANSPARENT on the parent layout.
Everyone is answering correctly about the transparency but not listening to what the guy needs in regards to the list scrolling behind the footer.
You need to make the footer part of your ListView
. At the moment the list won't scroll behind because the layout of the ListView does not go behind the footer view with the transparency. Make a RelativeLayout
and position the transparency at the bottom.
If you are looking for something like the text view on the image on the pulse app do this
android:background="#88000000"
android:textColor="#ffffff"
Try setting android:background="#00000000"
in TextView. Setting alpha of colour 00 will make the background transparent.
I haven't tried this, but it should work.
In case someone wants to do this in the programming way! Do the following: Update the color file in your values folder with this.
<?xml version="1.0" encoding="utf-8"?>
<resources>
<color name="transparent">#00ffffff</color> <!--This is the transparency line-->
</resources>
then call the transparency programitically
your_textview.setBackgroundResource(R.color.transparent);
Hi Please try with the below color code as textview's background.
android:background="#20535252"
try to set the transparency with the android-studio designer in activity_main.xml. If you want it to be transparent, write it for example like this for white: White: #FFFFFF, with 50% transparency: #80FFFFFF This is for Kotlin tho, not sure if that will work the same way for basic android (java).
<TextView android:alpha="0.3" ...
, for example.
setBackgroundColor(Color.TRANSPARENT);
The simplest way
Below code for black:-
<color name="black">#000000</color>
Now if i want to use opacity than you can use below code :-
<color name="black">#99000000</color>
and below for opacity code:-
Hex Opacity Values
100% — FF
95% — F2
90% — E6
85% — D9
80% — CC
75% — BF
70% — B3
65% — A6
60% — 99
55% — 8C
50% — 80
45% — 73
40% — 66
35% — 59
30% — 4D
25% — 40
20% — 33
15% — 26
10% — 1A
5% — 0D
0% — 00
Although this answer is very late but might help other developer so I'm posting it here.
Answers above showing only how to set transparent background of TextView. We can achieve transparent Textview backcgorund in two way:
Second approach is better because it gives flexibility to set background with different color and then setting setting opacity to widget using android:alpha="0.2"
Example
<TextView
android:id="@+id/tv_name"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@color/black"
android:alpha="0.3"
android:textColor="@color/white"
android:textStyle="bold"/>
See the Android Color resource documentation for reference.
Basically you have the option to set the transparency (opacity) and the color either directly in the layout or using resources references.
The hex value that you set it to is composed of 3 to 4 parts:
Alpha (opacity), i'll refer to that as aa
Red, i'll refer to it as rr
Green, i'll refer to it as gg
Blue, i'll refer to it as bb
Without an alpha (transparency) value:
android:background="#rrggbb"
or as resource:
<color name="my_color">#rrggbb</color>
With an alpha (transparency) value:
android:background="#aarrggbb"
or as resource:
<color name="my_color">#aarrggbb</color>
The alpha value for full transparency is 00 and the alpha value for no transparency is FF.
See full range of hex values below:
100% — FF
95% — F2
90% — E6
85% — D9
80% — CC
75% — BF
70% — B3
65% — A6
60% — 99
55% — 8C
50% — 80
45% — 73
40% — 66
35% — 59
30% — 4D
25% — 40
20% — 33
15% — 26
10% — 1A
5% — 0D
0% — 00
You can experiment with values in between those.
