Here i'm going to show you how to work with input type controls in android and how to change keyboard layouts in android studio.
What is Input Type Controls in Android ?
Input type controls means specifying the Keyboard Type (layouts).
You should always declare the input method in your editText by adding the android:inputType attribute to the <EditText>.
e.g :: If you have one editText in your app and you wish to display only numbers (0 to 9) in your keyboard just add android:inputType="number".
Example ::
activity_main.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout 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"
android:orientation="vertical"
android:padding="9dp"
tools:context=".MainActivity">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:layout_marginBottom="20dp"
android:layout_marginTop="20dp"
android:padding="8dp"
android:text="Input Type Controls\nKey Board Layouts"
android:textColor="#f00"
android:textSize="35sp" />
<EditText
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:hint="textPersonName"
android:inputType="textPersonName" />
<EditText
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:hint="number"
android:inputType="number" />
<EditText
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:hint="textEmailAddress"
android:inputType="textEmailAddress" />
<EditText

android:layout_height="wrap_content"
android:hint="date"
android:inputType="date" />
<EditText
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:hint="time"
android:inputType="time" />
</LinearLayout>
