Black text appears grey in Android View - android

I'm using a ViewFlipper to alternate some different RelativeLayouts. My layout is very simple.
<RelativeLayout
android:id="#+id/display_info_layout"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical"
android:background="#FFFFFF" >
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:layout_marginLeft="25dp"
android:layout_marginRight="25dp"
android:layout_marginTop="20dp"
android:text="#string/information"
android:color="#color/black" />
</RelativeLayout>
THE PROBLEM:
The color named "black" is defined in my resources as "#000000". The text elements appear the correct black color in other layouts, but in this one it appears a dull grey.
Other Layout
This Layout
THE QUESTIONS:
What could be causing this?
How do I fix it?

You should be using android:textColor I don't think android:color exists as an attribute
So:
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:layout_marginLeft="25dp"
android:layout_marginRight="25dp"
android:layout_marginTop="20dp"
android:text="#string/information"
android:textColor="#color/black" />

ContextCompat.getColor(getContext(), color) fixed the issue for me

Parent Relative Layout Foreground Color affecting Textview Color

I need relative layout background with some transparent for that i used gradient option, But it is affecting text view color also , I gave color of text view is white color but it looks like gray color. Please help me to get out of this issue.
<RelativeLayout

</RelativeLayout>
and image overlay code,
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<gradient
android:startColor="#B0000000"
android:centerColor="#A0000000"
android:endColor="#00FFFFFF"
android:angle="270"
/>
</shape>
<color name="White">#FFFFFF</color>
You can use #83000000 color code for setting transparency and that too in android:background instead of android:background property. Alternatively, you can also use "android:aplha="0.x" where 1 < x < 9, for transparency. Your final code will look like this.
<RelativeLayout android:id="#+id/topLayout1"
android:layout_width="match_parent"
android:layout_height="210dp"
android:layout_alignParentTop="true"
android:background="#83000000"

<RelativeLayout
android:id="#+id/topLayout"
android:layout_width="match_parent"
android:layout_height="match_parent">
<TextView
android:id="#+id/resName"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:layout_marginTop="100dp"
android:text="Green Way"

android:layout_below="#+id/resName"

android:layout_marginTop="5dp"
android:text="Items"
android:textColor="#FFFFFF"
android:textSize="16sp" />
</RelativeLayout>
You should see this ANSWER to know more about transparency. You can use various hex codes to achieve different level of transparency. Like for 50% transparency 80 code is used and color code would be like #80000000. Similary, you can use various codes in the scheme #xx000000.

Android Button/TextView styling

I want to have a button like this.
It's basically a Text: NEXT with a Chevron on the right side.
I already tried a button with transparent background and android:drawableRight, but the padding of the drawable was looking weird.
How can I achieve the wanted look?
What I have so far:
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Next"
android:textColor="#color/colorAccent"
android:drawableRight="#drawable/chevron_right"
android:background="#00000000"/>
/Sorry for posting a link and not the photo directly, but my reputations aren't high enough./
You can do it using a FrameLayout/RelativeLayout containing the ImageButton and an horizontal LinearLayout/RelativeLayout which contains the text and the chevron image aligned to the right. Something like this:
<FrameLayout
android:id="#+id/fl_btn_container"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<ImageButton
android:id="#+id/imbtn_btn_bg"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#null"
android:src="#drawable/white_drawable" />
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="center_vertical">
<TextView
android:id="#+id/tv_btn_text"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:layout_marginRight="10dp"
android:gravity="center_horizontal"
android:text="#string/next" />
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_toRightOf="#id/tv_btn_text"
android:src="#drawable/chevron" />
</RelativeLayout>
</FrameLayout>
This example is from my app, probably you'll need to adapt it.
Have you tried setting the spaces between the views of chevron and borders with negative values of dp .
I had a similar problem last year and a proper combination of positive and negative dp fixed it
You can use android:drawablePadding="8dp" to set the padding between the text and the drawable.
I'm not sure what you want but that's how I will do the button you attached
<RelativeLayout
android:layout_width="80dp"
android:background="#color/colorAccent"
android:layout_height="40dp">
<LinearLayout
android:layout_width="wrap_content"
android:layout_centerInParent="true"
android:layout_height="wrap_content">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="NEXT"/>
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#android:drawable/arrow_up_float"/>
</LinearLayout>
</RelativeLayout>

TextView Selectable and drawable background

I've TextView. I need to make it clickable, white and with "selectable effect", besides I need it to have a rectangular white border, to fake a button borders:
<TextView
android:id="#+id/test"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="?android:selectableItemBackground"
android:background="#drawable/white_empty_rectangle"
android:clickable="true"
android:padding="10dp"
android:text="Test"
android:textColor="#color/white" />
I can't set two background properties...how can I somehow "intersect" the two properties?
EDIT: I only need the borders of the rectangle, so it is "empty", I should see the background color behind the TextView.
Check this answer https://stackoverflow.com/a/5295522/4848308 you should use background selector.
This one to achieve border line background https://stackoverflow.com/a/3496310/4848308
I hope it helps!
What about this?
<FrameLayout
android:id="#+id/frame_test"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="?android:selectableItemBackground"
android:clickable="true">
<TextView
android:id="#+id/test"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#drawable/rectangle_empty_white"
android:padding="8dp"
android:text="#string/test"
android:textAllCaps="true"
android:textColor="#color/white"
android:textSize="14sp" />
</FrameLayout>

How to place button inside of EditText

I want to place an image button inside of EditText, but I don't have Idea please tell me how to do so as shown in the figure . Thanks
If You dont want click on that Image, Then you can use drawableRight property for EditText..
android:drawableRight="#drawable/icon"
If you want click then use below code.
<?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="wrap_content" >
<EditText
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:hint="Enter search key" />
<ImageButton
android:id="#+id/button1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:src="#drawable/search"
android:layout_centerVertical="true"
android:layout_margin="5dp"
android:text="Button"/>
</RelativeLayout>
If you want such layout and also image as clickable then you can do something like this
<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" >
<EditText
android:id="#+id/editText1"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_centerVertical="true" >
</EditText>
<ImageView
android:id="#+id/imageView1"
android:padding="5dp"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignTop="#+id/editText1"
android:layout_alignBottom="#+id/editText1"
android:layout_alignRight="#+id/editText1"
android:src="#drawable/ic_launcher" />
</RelativeLayout>
Output:
In Material, there is that underline under EditText. In most applications the icons appear inside that underlining.
For that purpose, just use padding
android:paddingEnd = "#dimen/my_button_size"
Don't forget paddingRight for sub 4.2 versions.
<RelativeLayout ....>
...
<EditText
...
android:id="#+id/my_text_edit"
android:textAlignment = "viewStart"
android:paddingEnd = "#dimen/my_button_size"
android:paddingRight = "#dimen/my_button_size"
.../>
<ImageButton
....
android:layout_width="#dimen/my_button_size"
android:layout_height="#dimen/my_button_size"
android:layout_alignEnd="#id/my_text_edit"
android:layout_alignRight="#id/my_text_edit"/>
...
</RelativeLayout>
It will limit the text to the image and the image will not overlap the text, however long the text may be.
My solution will fit all screen sizes without the editText going "behind" the imageButton. This also uses android resources, so you do not need to provide your own icon or string resource. Copy and paste this snippet wherever you would like a search bar:
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal">
<EditText
android:layout_margin="8dp"
android:id="#+id/etSearch"
android:hint="#android:string/search_go"
android:layout_weight="1"
android:layout_width="0dp"
android:layout_height="wrap_content"/>
<ImageView
android:id="#+id/ivSearch"
android:background="#color/transparent_black"
android:padding="2dp"
android:layout_width="wrap_content"
android:layout_margin="8dp"
android:src="#android:drawable/ic_menu_search"
android:layout_height="wrap_content"
tools:ignore="contentDescription" />
</LinearLayout>
Restult:
you can Use the Below Code :
android:drawableRight="#android:drawable/ic_menu_search"
How about placing it in a RelativeLayout like this ?:
<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">
<!-- EditText for Search -->
<EditText android:id="#+id/inputSearch"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:hint="Search whatever..."
android:textSize="14dp"
android:textStyle="italic"
android:drawableLeft="#drawable/magnifyingglass"
android:inputType="textVisiblePassword"
android:theme="#style/EditTextColorCustom"/>
<Button
android:id="#+id/btn_clear"
android:layout_width="14dp"
android:layout_height="14dp"
android:layout_marginTop="10dp"
android:layout_alignRight="#+id/inputSearch"
android:layout_marginRight="5dp"
android:background="#drawable/xbutton"
android:visibility="gone"/>
</RelativeLayout>
Also this way you´ll be able to handle the visibility of the Button (GONE / VISIBLE) in code.
Hope it helps.
Place your EditText inside a linear layout (horizontal) and add a Image Button next to it (0 padding). Setting the background color of EditText and ImageButton will blend in.
There's solution with clickable compound drawable. It's working very well - I have tested it
SOLUTION
This is pretty simple I feel. Use relative layout as your parent layout.
Place the editText to left and ImageButton to the right using either,
alignRight property for the ImageButton
by specifying the layout weight for each of the fields
In the accepted answer the ripple effect doesn't work, it stays behind the button in the back.
This example has 2 buttons in the textbox.
The ripple effect works because the parent layout has
android:background="#android:color/transparent"
To make sure the ripple works and doesn't stay on the back, set the imagebutton's parent background to transparent.
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#android:color/transparent"
android:focusableInTouchMode="true"
android:layout_margin="4dp">
<EditText
android:id="#+id/editText"
style="#android:style/TextAppearance.Medium"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginLeft="2dp"
android:layout_marginTop="2dp"
android:layout_marginRight="2dp"
android:background="#drawable/shape_textbox"
android:hint="text"
android:imeOptions="actionDone"
android:importantForAutofill="no"
android:inputType="text" />
<ImageButton
android:id="#+id/btn1"
android:layout_width="44dp"
android:layout_height="44dp"
android:layout_centerVertical="true"
android:layout_margin="5dp"
android:layout_toStartOf="#+id/btn2"
android:background="?android:selectableItemBackgroundBorderless"
android:src="#drawable/ic_btn1" />
<ImageButton
android:id="#+id/btn2"
android:layout_width="44dp"
android:layout_height="44dp"
android:layout_alignParentEnd="true"
android:layout_centerVertical="true"
android:layout_margin="5dp"
android:background="?android:selectableItemBackgroundBorderless"
android:contentDescription="#string/clear"
android:src="#drawable/ic_btn2" />
</RelativeLayout>
Or you can also wrap your button in a frame layout:
<FrameLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#android:color/transparent"
android:layout_alignParentEnd="true"
android:layout_centerVertical="true"
>
<ImageButton ... />
</FrameLayout>
I don't know why you want to place ImageButton to achieve, which can be done with simple property of EditText
android:drawableRight="your drawable"
Can't it be work for you?
Use the android:drawableLeft property on the EditText.
<EditText
...
android:drawableLeft="#drawable/my_icon" />

How to show the text on a ImageButton?

I have an ImageButton and I want to show a text and an image on it. But when I try on emulator:
<ImageButton
android:text="OK"
android:id="#+id/buttonok"
android:src="#drawable/buttonok"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
I get the image but without the text. How can I show the text? Please help me!
As you can't use android:text I recommend you to use a normal button and use one of the compound drawables. For instance:
<Button
android:id="#+id/buttonok"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:drawableLeft="#drawable/buttonok"
android:text="OK"/>
You can put the drawable wherever you want by using: drawableTop, drawableBottom, drawableLeft or drawableRight.
UPDATE
For a button this too works pretty fine. Putting android:background is fine!
<Button
android:id="#+id/fragment_left_menu_login"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#drawable/button_bg"
android:text="#string/login_string" />
I just had this issue and is working perfectly.
It is technically possible to put a caption on an ImageButton if you really want to do it. Just put a TextView over the ImageButton using FrameLayout. Just remember to not make the Textview clickable.
Example:
<FrameLayout>
<ImageButton
android:id="#+id/button_x"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#null"
android:scaleType="fitXY"
android:src="#drawable/button_graphic" >
</ImageButton>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:clickable="false"
android:text="TEST TEST" >
</TextView>
</FrameLayout>
Guys I need to develop the setting and logout button, I used the below code.
<Button
android:id="#+id/imageViewLogout"
android:layout_width="100dp"
android:layout_height="wrap_content"
android:layout_margin="#dimen/size_30dp"
android:layout_alignParentLeft="true"
android:text="Settings"
android:drawablePadding="10dp"
android:background="#android:color/transparent"
android:layout_alignParentBottom="true"
android:drawableTop="#drawable/logout" />
Actually, android:text is not an argument accepted by ImageButton
but, If you're trying to get a button with a specified background (not android default) use the android:background xml attribute, or declare it from the class with .setBackground();
I solved this by putting the ImageButton and TextView inside a LinearLayout with vertical orientation. Works great!
<LinearLayout
android:id="#+id/linLayout"
android:layout_width="80dp"
android:layout_height="wrap_content"
android:orientation="vertical" >
<ImageButton
android:id="#+id/camera_ibtn"
android:layout_width="60dp"
android:layout_height="60dp"
android:layout_gravity="center"
android:background="#drawable/camera" />
<TextView
android:id="#+id/textView2"
android:layout_width="80dp"
android:layout_height="wrap_content"
android:gravity="center"
android:text="#string/take_pic"
android:textColor="#FFFFFF"
android:textStyle="bold" />
</LinearLayout>
You can use a LinearLayout instead of using Button it's an arrangement i used in my app
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_margin="20dp"
android:background="#color/mainColor"
android:orientation="horizontal"
android:padding="10dp">
<ImageView
android:layout_width="50dp"
android:layout_height="50dp"
android:background="#drawable/ic_cv"
android:textColor="#color/offBack"
android:textSize="20dp" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_margin="10dp"
android:text="#string/cartyCv"
android:textColor="#color/offBack"
android:textSize="25dp" />
</LinearLayout>
you can use a regular Button and the android:drawableTop attribute (or left, right, bottom) instead.
Best way:
<Button
android:text="OK"
android:id="#+id/buttonok"
android:background="#drawable/buttonok"
android:layout_width="match_parent"
android:layout_height="wrap_content"/>
Heres a nice circle example:
drawable/circle.xml:
<?xml version="1.0" encoding="utf-8"?>
<shape
xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="oval">
<solid
android:color="#ff87cefa"/>
<size
android:width="60dp"
android:height="60dp"/>
</shape>
And then the button in your xml file:
<Button
android:id="#+id/btn_send"
android:layout_width="60dp"
android:layout_height="60dp"
android:background="#drawable/circle"
android:text="OK"/>
Here is the solution
<LinearLayout
android:id="#+id/buttons_line1"
android:layout_centerHorizontal="true"
android:layout_centerVertical="true"
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<ImageButton
android:id="#+id/btn_mute"
android:src="#drawable/btn_mute"
android:background="#drawable/circle_gray"
android:layout_width="60dp"
android:layout_height="60dp"/>
<ImageButton
android:id="#+id/btn_keypad"
android:layout_marginLeft="50dp"
android:src="#drawable/btn_dialpad"
android:background="#drawable/circle_gray"
android:layout_width="60dp"
android:layout_height="60dp"/>
<ImageButton
android:id="#+id/btn_speaker"
android:layout_marginLeft="50dp"
android:src="#drawable/btn_speaker"
android:background="#drawable/circle_gray"
android:layout_width="60dp"
android:layout_height="60dp"/>
</LinearLayout>
<LinearLayout
android:layout_below="#+id/buttons_line1"
android:layout_centerHorizontal="true"
android:layout_centerVertical="true"
android:layout_marginTop="10dp"
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<TextView
android:text="mute"
android:clickable="false"
android:textAlignment="center"
android:textColor="#color/Grey"
android:layout_width="60dp"
android:layout_height="wrap_content"/>
<TextView
android:text="keypad"
android:clickable="false"
android:layout_marginLeft="50dp"
android:textAlignment="center"
android:textColor="#color/Grey"
android:layout_width="60dp"
android:layout_height="wrap_content"/>
<TextView
android:text="speaker"
android:clickable="false"
android:layout_marginLeft="50dp"
android:textAlignment="center"
android:textColor="#color/Grey"
android:layout_width="60dp"
android:layout_height="wrap_content"/>
</LinearLayout>
Best way to show Text on button(with image)
Your Question: How to show text on imagebutton?
Answer: You can not display text with imageButton. Method that tell in Accepted answer also not work.
because
If you use android:drawableLeft="#drawable/buttonok" then you can not set drawable in center of button.
If you use android:background="#drawable/button_bg" then color of your drawable will be changed.
In android world there are thousands of option to do this. But here i provide best alternate according to my point of view. (see below)
Solution: Use cardView with LinearLayout
Your drawable/image use in LinearLayout because it shows in center. And with help of textView you can set text on this. We makes cardView background to transparent.
<androidx.cardview.widget.CardView
android:layout_width="match_parent"
android:layout_height="99dp"
android:layout_margin="16dp"
app:cardBackgroundColor="#android:color/transparent"
app:cardElevation="0dp"
app:cardUseCompatPadding="true">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#drawable/your_selected_image"
>
<TextView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:text="Happy Coding"
android:textSize="33sp"
android:gravity="center"
>
</TextView>
</LinearLayout>
</androidx.cardview.widget.CardView>
here i explain some terms:
app:cardBackgroundColor="#android:color/transparent" for make transparent background of cardView
app:cardElevation="0dp" for hide evelation lines around cardView
app:cardUseCompatPadding="true" its provide actual size of cardView. Always use this when you use cardView
set your image/drawable in LinearLayout as a background.
Sorry, for my Bad English.
Happy Coding:)
ImageButton can't have text (or, at least, android:text isn't listed in its attributes).
The Trick is:
It looks like you need to use Button (and look at drawableTop or setCompoundDrawablesWithIntrinsicBounds(int,int,int,int)).
