Time converter for convert time into hour,minute or in a second and rate per hour or minute

In this example we will learn convert time into hour,minute or in a second. and also convert rate per hour or minute.

Step 1: Write code into activity_main.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:orientation="vertical" >


    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="fill_parent"
        android:orientation="vertical" >

        <TextView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="Time converter" />

        <Spinner
            android:id="@+id/Spinner01"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:spinnerMode="dialog"
            android:textColor="#A72CFC" />

        <EditText

                android:layout_height="match_parent"
                android:layout_weight="1"
                android:text="hour" />

            <Button
                android:id="@+id/btm1"

                android:layout_height="match_parent"
                android:layout_weight="1"
                android:text="second" />
        </LinearLayout>

        <TextView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="Rate per hour or minute" />

        <Spinner
            android:id="@+id/Spinner02"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"

            android:spinnerMode="dialog" />

        <EditText
            android:id="@+id/EditText02"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:ems="10"
            android:hint="value"
            android:inputType="number"
            android:textColor="#fff" />

        <EditText
            android:id="@+id/EtRs"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:ems="10"
            android:hint="@string/enter_rupi"
            android:inputType="number"
            android:textColor="#fff" />

        <TextView

            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:text="answer" />

        <LinearLayout
            android:layout_width="match_parent"
            android:layout_height="match_parent" >

            <Button
                android:id="@+id/bth2"

                android:layout_height="match_parent"
                android:layout_weight="1"
                android:text="minute" />
        </LinearLayout>


Step 2:Write code into spineritem.xml 

its custom spiner, you can create your own style.e.g change background color or font color etc.

<TextView
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/textView1"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:textSize="17sp"
    android:padding="8dp"
    android:gravity="center"
    android:textStyle="normal"
    android:textColor="#020202">
 
</TextView>
