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"

Button Border Not Showing

I try to put a border for a button in android but unfortunately I can't see the button border.
Drawable File 👇
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item>
<shape android:shape="rectangle">
<corners android:radius="12dp" />
<stroke android:width="3px" android:color="#7E8082" />
</shape>
</item>
</selector>
XML 👇
<Button
android:id="#+id/btn_signup"
android:layout_width="match_parent"
android:layout_height="60dp"
android:layout_marginTop="122dp"
android:background="#drawable/bg_signup"
android:fontFamily="#font/poppins_semibold"
android:text="Create an Account"
android:textAllCaps="false"
android:textColor="#color/black"
app:layout_constraintTop_toBottomOf="#+id/btn_login" />

You don't need to use a custom drawable, just use a MaterialButton:
<com.google.android.material.button.MaterialButton
android:layout_width="wrap_content"
android:layout_height="wrap_content"
style="#style/Widget.MaterialComponents.Button.OutlinedButton"
app:strokeColor="#7E8082"
app:strokeWidth="1dp"
app:cornerRadius="12dp"/>

Don't use a selector for single option use shape directly
bg_signup
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<solid android:color="#cdcdcd"/>
<corners
android:radius="4dp"
/>
<stroke
android:width="1dp"
android:color="#000"
/>
</shape>

use Style attribute instead of android:background="#drawable/bg_signup"
make a custom style then call it android:style="#style/bg_signup"

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.

change the appearance of button into round button

I want to made the present rectangular button into round shape and add the picture of share button in it. I mean the button should be of round share and it should have only image(fit) of "share"
<Button
android:id="#+id/button3"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_marginEnd="10dp"
android:layout_marginTop="8dp"
android:text="03"
android:textStyle="bold"/>

Create drawable file as bg_share.xml
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<solid
android:color="#color/colorPrimaryDark">
</solid>
<corners
android:radius="500dp">
</corners>
<padding
android:top="0dp"
android:right="10dp"
android:left="10dp"
android:bottom="0dp">
</padding>
</shape>
And in your main.xml create imageview instead of button like
<ImageView
android:id="#+id/share"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#drawable/bcshare"
android:padding="10dp"
android:src="#drawable/ic_share_black_24dp" />
In MainActivity.java do something like this
share.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
//Your code...
}
});

You can find the answer Here
create a resource drawable
<shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="rectangle">
<stroke android:width="1dp" android:color="#FF404040" />
<corners android:radius="6dp" />
<gradient android:startColor="#FF6800" android:centerColor="#FF8000" android:endColor="#FF9700" android:angle="90" />
</shape>
then set to the button background .
android:background="#drawable/button_background"

you can create a separate drawable and implement round shape. Then set the drawable to the background of the button as below
Create a drawable file as circle_button.xml
<?xml version="1.0" encoding="utf-8"?>
<shape
xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="oval">
<solid
android:color="#008577"/>
<size
android:width="120dp"
android:height="120dp"/>
</shape>
Then change the layout as follows
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#drawable/circle_button"
android:text="Button"/>

Create an xml in drawable folder and name it like: "round.xml" and use this xml in your given button background.
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<solid android:color="#eeffffff" />
<corners android:bottomRightRadius="8dp"
android:bottomLeftRadius="8dp"
android:topRightRadius="8dp"
android:topLeftRadius="8dp"/>
</shape>
and to your button in layout xml you can use the last line to set background
<Button
android:id="#+id/button3"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_marginEnd="10dp"
android:layout_marginTop="8dp"
android:text="03"
android:textStyle="bold"
android:background="#drawable/round"/>

You can use the standard MaterialButton with the Widget.MaterialComponents.Button.Icon style.
Something like:
<com.google.android.material.button.MaterialButton
android:layout_width="48dp"
android:layout_height="48dp"
style="#style/Widget.MaterialComponents.Button.Icon"
app:icon="#drawable/ic_share"
app:iconSize="24dp"
app:iconPadding="0dp"
android:insetLeft="0dp"
android:insetTop="0dp"
android:insetRight="0dp"
android:insetBottom="0dp"
app:shapeAppearanceOverlay="#style/ShapeAppearanceOverlay.MyApp.Button.Rounded"
/>
Use the app:shapeAppearanceOverlay to get rounded corners. In this way you will have a circle.
<style name="ShapeAppearanceOverlay.MyApp.Button.Rounded" parent="">
<item name="cornerFamily">rounded</item>
<item name="cornerSize">32dp</item>
</style>

thanks in advance

I think your red color is set in this line in your edittext shape:
<stroke android:width="1dip" android:color="#c66262" />
maybe set here:
<stroke android:width="1dip" android:color="#000000" />
for a black stroke
Edit: this is for making red line black. I misunderstood question a bit. Anyhow I think would look nicer this way. My few cents ;-)
Anyhow, if you don't want the black line, then just set the black line (#000000) to let's say white:
<stroke android:width="1dip" android:color="#ffffff" />
or simply get rid of it at all, by just deleting this code here, which looks like it is your black stroke:
<stroke android:width="1dip" android:color="#000000" />
<corners
android:bottomRightRadius="10dp"
android:bottomLeftRadius="10dp"
android:topLeftRadius="10dp"
android:topRightRadius="10dp"/>

Just remove following line from drawable(searchview):
stroke android:width="1dip" android:color="#000000"
