Android Tutorials

In this tutorial, I will explain the concept of EditText and TextView controls provided in Android. If you are new to android then see Getting Started with Android.

• EditText is used to get value from user (Input control).
• TextView is used to display value on the screen (Output control).

From the above two lines, now you have a rough idea about what these controls are. So now i will use an example where these two controls can be used. See the output bellow.

Make following .xml file

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"     xmlns:tools="http://schemas.android.com/tools"     android:layout_width="match_parent"     android:layout_height="match_parent"     android:paddingBottom="@dimen/activity_vertical_margin"     android:paddingLeft="@dimen/activity_horizontal_margin"     android:paddingRight="@dimen/activity_horizontal_margin"     android:paddingTop="@dimen/activity_vertical_margin"     tools:context=".MainActivity" >     <TextView         android:id="@+id/textView1"         android:layout_width="wrap_content"         android:layout_height="wrap_content"         android:layout_alignParentLeft="true"         android:layout_alignParentTop="true"         android:layout_marginTop="39dp"         android:text="@string/username"         android:textAppearance="?android:attr/textAppearanceLarge" />     <TextView         android:id="@+id/textView2"         android:layout_width="wrap_content"         android:layout_height="wrap_content"         android:layout_alignRight="@+id/textView1"         android:layout_below="@+id/textView1"         android:layout_marginTop="32dp"         android:text="@string/password"         android:textAppearance="?android:attr/textAppearanceLarge" />     <EditText         android:id="@+id/editText1"         android:layout_width="wrap_content"         android:layout_height="wrap_content"         android:layout_alignTop="@+id/textView1"         android:layout_marginLeft="38dp"         android:layout_toRightOf="@+id/textView1"         android:ems="10" >         <requestFocus />     </EditText>     <EditText         android:id="@+id/editText2"         android:layout_width="wrap_content"         android:layout_height="wrap_content"         android:layout_alignBaseline="@+id/textView2"         android:layout_alignBottom="@+id/textView2"         android:layout_alignLeft="@+id/editText1"         android:ems="10"         android:inputType="textPassword" /> </RelativeLayout>
