In android, EditText is a user interface control which is used to allow the user to enter or modify the text. While using EditText control in our android applications, we need to specify the type of data the text field can accept using the inputType attribute.

For example, if it accept plain text, then we need to specify the inputType as “text”. In case if EditText field is for password, then we need to specify the inputType as “textPassword”.

In android, EditText control is an extended version of TextView control with additional features and it is used to allow users to enter input values.

In android, we can create EditText control in two ways either in XML layout file or create it in Activity file programmatically.

Create a EditText in Layout File

Following is the sample way to define EditText control in XML layout file in android application.

<?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='match_parent'
android:orientation='vertical' >
<EditText
android:id='@+id/txtSub'
android:layout_width='match_parent'
android:layout_height='wrap_content'
android:hint='Subject'
android:inputType='text'/>
</LinearLayout>

If you observe above code snippet, here we defined EditText control to accept plain text by using inpuType as “text” in xml layout file.

Create EditText Control in Activity File

In android, we can create EditText control programmatically in an activity file to allow users to enter text based on our requirements.

Following is the example of creating EditText control dynamically in an activity file.

public class MainActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
LinearLayout linearLayout = (LinearLayout) findViewById(R.id.linearlayout);
EditText et = new EditText(this);
et.setHint('Subject');
linearLayout.addView(et);
}
}

Set the Text of Android EditText

In android, we can set the text of EditText control either while declaring it in Layout file or by using setText() method in Activity file.

Following is the example to set the text of TextView control while declaring it in XML Layout file.

If you observe above example we used android:text property to the set required text for EditText control in XML Layout file.

Following is another way to set the text of EditText control programmatically in activity file using setText() method.

If you observe above code snippet, we are finding the EditText control which we defined in XML layout file using id property and setting the text using setText() method.

Get Text of Android EditText

In android, we can get the text of EditText control by using getText() method in Activity file.

Following is the example to get text of EditText control programmatically in activity file using getText() method.

public class MainActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
EditText et = (EditText) findViewById(R.id.txtSub);
String name = et.getText().toString();
}
}

If you observe above code snippet, we are finding the EditText control which we defined in XML layout file using id property and getting the text of EditText control using getText() method.

Android EditText Attributes

The following are some of the commonly used attributes related to EditText control in android applications.

Android EditText Control Example

Following is the example of using multiple EditText controls with different input types like password, phone, etc. in LinearLayout to build an android application.

Create a new android application using android studio and give names as EditTextExample. In case if you are not aware of creating an app in android studio check this article Android Hello World App.

Now open an activity_main.xml file from reslayout path and write the code like as shown below

Pad Editor Rekordbox

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='match_parent'
android:paddingLeft='40dp'
android:orientation='vertical' android:id='@+id/linearlayout' >
<EditText
android:id='@+id/txtName'
android:layout_width='wrap_content'
android:layout_height='wrap_content'
android:layout_marginTop='25dp'
android:ems='10'
android:hint='Name'
android:inputType='text'
android:selectAllOnFocus='true' />
<EditText
android:id='@+id/txtPwd'
android:layout_width='wrap_content'
android:layout_height='wrap_content'
android:ems='10'
android:hint='Password 0 to 9'
android:inputType='numberPassword' />
<EditText
android:id='@+id/txtEmai'
android:layout_width='wrap_content'
android:layout_height='wrap_content'
android:ems='10'
android:hint='Email'
android:inputType='textEmailAddress' />
<EditText
android:id='@+id/txtDate'
android:layout_width='wrap_content'
android:layout_height='wrap_content'
android:layout_below='@+id/editText3'
android:ems='10'
android:hint='Date'
android:inputType='date' />
<EditText
android:id='@+id/txtPhone'
android:layout_width='wrap_content'
android:layout_height='wrap_content'
android:ems='10'
android:hint='Phone Number'
android:inputType='phone'
android:textColorHint='#FE8DAB'/>
<Button
android:id='@+id/btnSend'
android:layout_width='wrap_content'
android:layout_height='wrap_content'
android:text='submit'
android:textSize='16sp'
android:textStyle='normal|bold' />
<TextView
android:layout_width='wrap_content'
android:layout_height='wrap_content'
android:id='@+id/resultView'
android:layout_marginTop='25dp'
android:textSize='15dp'/>
</LinearLayout>

If you observe above code we created multiple EditText controls with different inputTypes, such as password, email address, date, phone number, plain text.

Once we are done with the creation of layout with required controls, we need to load the XML layout resource from our activityonCreate() callback method, for that open main activity file MainActivity.java from javacom.tutlane.edittextexample path and write the code like as shown below.

MainActivity.java

package com.tutlane.edittextexample;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.widget.TextView;
import org.w3c.dom.Text;
public class MainActivity extends AppCompatActivity {
Button btnSubmit;
EditText name, password, email, dob, phoneno;
TextView result;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
name=(EditText)findViewById(R.id.txtName);
password = (EditText)findViewById(R.id.txtPwd);
email = (EditText)findViewById(R.id.txtEmai);
dob = (EditText)findViewById(R.id.txtDate);
phoneno= (EditText)findViewById(R.id.txtPhone);
btnSubmit = (Button)findViewById(R.id.btnSend);
result = (TextView)findViewById(R.id.resultView);
btnSubmit.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
if (name.getText().toString().isEmpty() || password.getText().toString().isEmpty() || email.getText().toString().isEmpty() || dob.getText().toString().isEmpty()
|| phoneno.getText().toString().isEmpty()) {
result.setText('Please Fill All the Details');
} else {
result.setText('Name - ' + name.getText().toString() + ' n' + 'Password - ' + password.getText().toString()
+ ' n' + 'E-Mail - ' + email.getText().toString() + ' n' + 'DOB - ' + dob.getText().toString()
+ ' n' + 'Contact - ' + phoneno.getText().toString());
}
}
});
}
}

If you observe above code we are calling our layout using setContentView method in the form of R.layout.layout_file_name in our activity file. Here our xml file name is activity_main.xml so we used file name activity_main and we are getting the text of our EditText controls whenever we click on button.

Generally, during the launch of our activity, the onCreate() callback method will be called by the android framework to get the required layout for an activity.

Output of Android EditText Example

When we run the above example using the android virtual device (AVD) we will get a result like as shown below.

If you observe the above result, the system displaying an appropriate on-screen keyboard for each EditText control based on the defined inputType attribute and displayed a message if we click on the button without entering details in fields.

Once we enter details in all fields and click on Button we will get a result like as shown below.

This is how we can use EditText control in android applications to allow the user to enter or modify the text based on our requirements.
