How to make the color of a TextView like this image?

I want to set the color of a textview like this image, It has a vertical red color line and entire textview is like pink or reddish color.

You can use a linear layout with orientation horizontal and put a view inside it.
<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout 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:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".FirstFragment">
<LinearLayout
android:background="#color/teal_200"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:layout_constraintBottom_toTopOf="#id/button_first"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent">
<View
android:layout_width="5dp"
android:background="#color/cardview_dark_background"
android:layout_height="match_parent"/>
<TextView
android:id="#+id/textview_first"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:paddingStart="5dp"
android:text="#string/hello_first_fragment"
android:background="#drawable/side_line"
/>
</LinearLayout>
<Button
android:id="#+id/button_first"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/next"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toBottomOf="#id/textview_first" /></androidx.constraintlayout.widget.ConstraintLayout>
Just change the colors and you are good to go.
The output looks like this...

You can use layer list. No need more views
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item>
<shape
android:shape="rectangle">
<solid android:color="#color/teal_700"/>
</shape>
</item>
<item android:start="5dp">
<shape
android:shape="rectangle">
<solid android:color="#color/teal_200"/>
</shape>
</item>
</layer-list>
In your TextView
android:background="#drawable/your_layer_list"

How do I add animation / styling to a button? Android Studio

I have a button
<Button
android:id="#+id/button"
android:layout_width="match_parent"
android:layout_height="45dp"
android:onClick="loginIsClicked"
android:layout_marginStart="8dp"
android:layout_marginTop="12dp"
android:layout_marginEnd="8dp"
android:background="#drawable/button"
android:text="#string/Auth"
android:textAllCaps="false"
android:textColor="#color/white"
android:textSize="16sp"
android:enabled="false" />
<?xml version="1.0" encoding="utf-8"?>
<shape android:shape="rectangle" xmlns:android="http://schemas.android.com/apk/res/android">
<solid android:color="#color/red"/>
<corners android:radius="10dp"/>
</shape>
How can I add animation to the button used in the default buttons?
Example:
enter image description here

If I understood correctly, what you are looking for is a ripple. Wrap your shape in a ripple as follows and provide your ripple color:
<ripple xmlns:android="http://schemas.android.com/apk/res/android"
android:color="#color/rippleColor">
<item>
<shape android:shape="rectangle">
<solid android:color="#color/red"/>
<corners android:radius="10dp"/>
</shape>
</item>
</ripple>

Add MaterialButton.
<com.google.android.material.button.MaterialButton
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_margin="16dp"
android:text="Button" />
Also do not forget to change theme Theme.AppCompat.Light.DarkActionBar to Theme.MaterialComponents.Light.DarkActionBar in styles.xml file.

setElevation does not show shadow

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.

Android : Create translucent edittext with image inside

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.

How can I achieve a gap in a border around a LinearLayout?

I want to have a gap in a border which is around a LinearLayout. In this gap there should be text.
I think the image explains it very well:
Is this possible? I know how to create a border around the Layout but not how to do this gap with the text. I hope someone can help me.

Make my_drawable.xml file in your project's res/drawable folder:
<shape
xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<stroke
android:width="2dp"
android:color="#000066" />
<corners
android:radius="10dp" />
<solid
android:color="#android:color/white"/>
</shape>
After it you can add it as a background for a LinearLayout:
<RelativeLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<LinearLayout
android:layout_width="300dp" <!-- Or whatever you want -->
android:layout_height="200dp" <!-- Or whatever you want -->
android:background="#drawable/my_drawable">
</LinearLayout>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#android:color/white"
android:layout_marginLeft="20dp"
android:textColor="#android:color/black"
android:textStyle="bold"
android:paddingLeft="10dp"
android:paddingRight="10dp"/>
</RelativeLayout>
