I want to achieve the background effect of the TextView at the bottom of the below image.
sorry for my poor english...
You can create your background drawable
your_drawable.xml
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="oval">
<gradient android:angle="0"
android:endColor="#fff"
android:startColor="#c86e6e6e"
android:gradientRadius="100dp"
android:type="radial"/>
</shape>
And add to textview:
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="TEST"
android:textColor="#fff"
android:background="#drawable/your_drawable"
android:padding="90dp"
android:textSize="30sp"/>
You have to use gradient scale. go Check documentation for more details

I have some issue with styling of my buttons. I use drawable to change shape and style my app buttons. When I add background in activity xml my buttons change shape but doesn't change background color but when I add background programmatically with "setBackgroundResource" method everything is ok.
There is my piece of code:
activity xml:
`<Button
android:id="#+id/button_traditional"
android:background="#drawable/button_default_main_app"
android:textColor="#color/mustard"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_marginStart="16dp"
android:layout_marginTop="75dp"
android:layout_marginEnd="32dp"
android:onClick="newGame"
android:text="#string/standard_game"
app:layout_constraintEnd_toStartOf="#+id/button_extended"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toBottomOf="#+id/text_gameChose" />
`
res/drawable:
<solid
android:color="#color/black"
/>
<corners
android:topLeftRadius="10dp"
android:topRightRadius="100dp"
android:bottomLeftRadius="100dp"
android:bottomRightRadius="10dp"
/>
Thanks in advance for your help.
Edit:
Whole drawable code:
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="rectangle">
<solid
android:color="#color/black"
/>
<corners
android:topLeftRadius="10dp"
android:topRightRadius="100dp"
android:bottomLeftRadius="100dp"
android:bottomRightRadius="10dp"
/>
</shape>
By default the button tint is the primary color. You need to set it to null for the drawable to take effect by setting.
app:backgroundTint="#null"
So your whole button would look like this:
<Button
android:id="#+id/button_traditional"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginStart="16dp"
android:layout_marginTop="75dp"
android:layout_marginEnd="32dp"
android:background="#drawable/button_default_main_app"
android:onClick="newGame"
android:text="Standard game"
android:textColor="#a00"
app:backgroundTint="#null" />
The result:
Hello guys so I want to add a border around my spinner. just a rectangular box would work. I have already added the border. The problem is that the border keeps the size of the biggest object in the list not the selected object.
Just if it is not clear, My problem is that I have a border(rectangular box) around the spinner which is great, but the size of of the box is the problem. the size of the box is determined by the largest object in the list. Instead, I want the size of the box to be determined by the selected object from the spinner. So if I choose test the box should be small but if I choose "ajidhfkljhfiidsff1233" the box should become bigger.
I already added a border but it is around the spinner
xml of spinner:

Thank you in advance guys any help would be appreciated. :) it is my 2 nd post of overflow
I can not draw the shadow with setElevation.I do not want to use a drawing to do this. Here is the code:
This is the parent.
Page.xml
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:background="#color/background">
<LinearLayout
android:id="#+id/pp_cont_new_list"
android:background="#color/background"
android:layout_width="match_parent"
android:layout_height="150dp"
android:gravity="center_horizontal"
android:orientation="vertical"
android:paddingLeft="30dp"
android:paddingRight="30dp"
android:paddingTop="5dp">
</LinearLayout>
</LinearLayout>
Here I build a simple layout.
PersonalPage.Java
final LinearLayout ROOT = (LinearLayout) findViewById( R.Id.pp_cont_new_list);
final LinearLayout LL = new LinearLayout(context); //Container
LL.setLayoutParams (new LinearLayout.LayoutParams(
Generic.PARAM_MP, //eq. match_parent
(int) context.getResources ().getDimension (R.dimen.bt_preview_list_height)
));
LL.setBackgroundResource (R.drawable.background_new_list);
LL.setElevation (5f);
LL.setClickable (true);
ROOT.addView( LL );
/*
* other code inner the container
*/
this background
background_new_list.xml
<?xml version="1.0" encoding="utf-8"?>
<layer-list
xmlns:android="http://schemas.android.com/apk/res/android">
<item>
<shape android:shape="rectangle">
<corners android:radius="10dp"/>
<solid android:color="#color/background"/>
</shape>
</item>
<item>
<ripple android:color="#color/textColorAlpha"/>
</item>
</layer-list>
I would like an explanation of my error.
And I would also like to know what to use for pre-LOLLIPOP.
set elevation just doesnot work for pre-lolipop
You can create a custom button image that has a shadow and set it as button background..or any view's background to give shadow effect
use ViewCompat.setElevation(your_view(in your case LL), elevation_amount);
but for devices pre-Lollipop this will not have effect,
for pre-Lollipop cases you might use:
android:background="#android:drawable/dialog_holo_light_frame"
This is working if you don't mind doing things in xml. I tried it out. I did not have background color value that you are using so I used a different color for parent layout.
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#E8E8E8"
android:paddingBottom="20dp"
android:clipToPadding="false"
android:translationZ="6dp">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="150dp"
android:background="#drawable/background_new_list"
android:clipToPadding="false"
android:elevation="25dp"
android:orientation="vertical"
/>
Note: I am using a higher elevation value just to make it easier to check if it's working. you can adjust it to what you need.
I am working on an Android project in which I have a login page where I want to add Username and password fields. The design I have requires me to put them in this translucent manner and with an image inside. Any ideas what I can change for EditText to make it translucent and shape it, there are many threads to make it transparent by setting the background to null or by color and so on, but nothing like this I found.
Design :
I am using Relative layout, and those icons on right side, I have them in separate PNG files. I can directly add them inside Edittext, but I am concerned that if the username and password is long, it will start going over the image. Any strategies for that? Thank you.
Code :
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:background="#drawable/background"
android:layout_width="match_parent"
android:layout_height="match_parent">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textAppearance="?android:attr/textAppearanceLarge"
android:text="Text"
android:id="#+id/textView"
android:textSize="32sp"
android:textColor="#color/common_signin_btn_dark_text_default"
android:layout_marginTop="75dp"
android:layout_alignParentTop="true"
android:layout_centerHorizontal="true" />
<EditText
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/editText"
android:layout_below="#+id/textView"
android:layout_marginTop="41dp"
android:layout_alignRight="#+id/textView"
android:layout_alignEnd="#+id/textView"
android:layout_alignLeft="#+id/textView"
android:layout_alignStart="#+id/textView" />
</RelativeLayout>
Updated screenshot
Updated EditText
<EditText
android:layout_width="wrap_content"
android:layout_height="45dp"
android:id="#+id/emailEditText"
android:inputType="textEmailAddress"
android:layout_below="#+id/textView"
android:layout_marginTop="41dp"
android:drawableEnd="#drawable/Mail"
android:drawableRight="#drawable/Mail"
android:maxLines="1"
android:ellipsize="end"
android:hint="Email"
android:textColorHint="#color/common_signin_btn_dark_text_focused"
android:background="#drawable/layout_bg"
android:layout_alignRight="#+id/textView"
android:layout_alignEnd="#+id/textView"
android:layout_alignLeft="#+id/textView"
android:layout_alignStart="#+id/textView" >
</EditText>
layout_bg.xml :
<?xml version="1.0" encoding="UTF-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<solid android:color="#color/traslucent_background" />
<stroke android:width="1dip" android:color="#B1BCBE" />
<corners android:radius="17dip"/>
<padding android:left="0dip" android:top="0dip" android:right="0dip" android:bottom="0dip" />
</shape>
For the image you should be able to use android:drawableEnd="#drawable/..." and android:drawableRight="#drawable/..." which also will limit the text length.
For the background you can define a custom drawable like this:
<!-- background_edittext.xml -->
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<corners android:radius="8dp" />
<solid android:color="#color/traslucent_background" />
</shape>
Where traslucent_color would be defined in colors.xml, for example, like this:
<color name="shadow_lighter_color">#64000000</color>
EDIT: this would be an example of how to use drawableEnd / drawableRight with a space between text and icon:
<EditText
android:background="#drawable/background_edittext"
android:drawablePadding="16dp"
android:drawableEnd="#drawable/icon"
android:drawableRight="#drawable/icon"
android:maxLines="1"
android:ellipsize="end"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
Try this:
Define a shape drawable in your project like this:
<shape
xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<solid android:color="#88ff0000"/>
<corners android:radius="32dp"/>
</shape>
And set it as the background for your EditTexts. Also, add this as an attribute to your EditText in the XML:
android:drawableRight="#drawable/any_drawable_file"
If you're concerned about the text overlapping with the drawable, you could add a custom paddingRight to your EditText to tackle that. It would save you the effort of inflating a custom layout.
I am making an app and I have an activity with a searchview. My point is that I want to change the background color of the text field (the black rectangle in screnn shot).
My drawable:
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle"
android:padding="10dp">
<solid android:color="#FFFFFF"/>
<corners
android:bottomRightRadius="10dp"
android:bottomLeftRadius="10dp"
android:topLeftRadius="10dp"
android:topRightRadius="10dp"/>
</shape>
My layout:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

Can anybody help me with that?
thanks
After a little detective work you'll see that if you look at the source for the SearchView widget, you will see it extends LinearLayout with some added functionality. Looking at the line #242 it contains a widget (specifically a SearchAutoComplete which extends the AutoCompleteTextView which in the end extends EditText.
With that said, you'll need to modify the background attribute of that child element, with something on the lines of this:
SearchView c = findViewById(R.id.searchView);
EditText e = (EditText)c.findViewById(c.getContext().getResources().getIdentifier("android:id/search_src_text", null, null));
e.setBackgroundColor(Color.BLACK); //←If you just want a color
e.setBackground(getResources().getDrawable(R.drawable.YOUR_DRAWABLE));
//↑ If you want a drawable ↑

Source for SearchView
Works for me:
mSearchView.findViewById(android.support.v7.appcompat.R.id.search_plate).setBackground...
Also for voice button:
mSearchView.findViewById(android.support.v7.appcompat.R.id.search_voice_btn).setBackground...
