In Android Development, EditText is a widget that you use to get some value from the user. It might be some text, number or whatever. In this post, I will tell you how to get the value entered by the user in EditText in your code for processing. There are three different types of values that you can get as input:
  • String value (Name or some other text)
  • Integer value (Positive and Negative Numbers without decimal point)
  • Decimal or Double values (Positive and Negative number with a decimal point)

Get String value from EditText

First, you need to create EditText that is capable of inputting text value from the user. For this, you will have to set android:inputType="text" in the XML. The XML code of EditText is:
    <EditText
        android:id="@+id/editText"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_marginStart="8dp"
        android:layout_marginLeft="8dp"
        android:layout_marginTop="8dp"
        android:layout_marginEnd="8dp"
        android:layout_marginRight="8dp"
        android:ems="10"
        android:inputType="text" />



To get its value in java code, first, find the EditText object and then extract its value.
EditText editText=findViewById(R.id.editText);
String value=editText.getText().toString();

Get Integer value from EditText

Create an EditText that is restricted to input signed or unsigned Integer. See the full guide on EditText with numbers here. You can set android:inputType="numberSigned" to input Integers.

    <EditText
        android:id="@+id/editText"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_marginStart="8dp"
        android:layout_marginLeft="8dp"
        android:layout_marginTop="8dp"
        android:layout_marginEnd="8dp"
        android:layout_marginRight="8dp"
        android:ems="10"
        android:inputType="numberSigned" />

Now get the Integer value in Java code. First, find the EditText, then get its value and then parse the value to Integer. Here it is also important to check if the EditText is empty. If it is empty, do not try to convert the received value to int. Otherwise, the application will crash.


EditText editText=findViewById(R.id.editText);
String temp=editText.getText().toString();
int value=0;
if (!"".equals(temp)){
     value=Integer.parseInt(temp);
}

Get Decimal or Double value from  EditText

Create EditText to input decimal values. See full instructions here. Set android:inputType="numberDecimal" in XML.

    <EditText
        android:id="@+id/editText"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_marginStart="8dp"
        android:layout_marginLeft="8dp"
        android:layout_marginTop="8dp"
        android:layout_marginEnd="8dp"
        android:layout_marginRight="8dp"
        android:ems="10"
        android:inputType="numberDecimal" />

Now get value in Java code. Make sure to check if the EditText is empty.

EditText editText=findViewById(R.id.editText);
String temp=editText.getText().toString();
double value=0;
if (!"".equals(temp)){
    value=Double.parseDouble(temp);
}



Get value from EditText and set it to TextView

First, we create an EditText, a button and a TextView in XML file. Following is the code for activity_main.xml

<?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=".MainActivity">

     <EditText
        android:id="@+id/editText"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_marginStart="8dp"
        android:layout_marginLeft="8dp"
        android:layout_marginTop="8dp"
        android:layout_marginEnd="8dp"
        android:layout_marginRight="8dp"
        android:ems="10"
        android:inputType="text"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toTopOf="parent" />

     <Button
        android:id="@+id/button"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginStart="8dp"
        android:layout_marginLeft="8dp"
        android:layout_marginTop="8dp"
        android:text="Button"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toBottomOf="@+id/editText" />

     <TextView
        android:id="@+id/textView"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_marginStart="8dp"
        android:layout_marginLeft="8dp"
        android:layout_marginTop="8dp"
        android:layout_marginEnd="8dp"
        android:layout_marginRight="8dp"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toBottomOf="@+id/button" />
</androidx.constraintlayout.widget.ConstraintLayout>

Now in the onClickListener of the button, get the value from EditText and set it to the TextView. Following is the code for MainActivity.java
package com.umersoftwares.edittext;

 import androidx.appcompat.app.AppCompatActivity;

 import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.widget.TextView;

 public class MainActivity extends AppCompatActivity {

     @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        final EditText editText=findViewById(R.id.editText);
        Button button=findViewById(R.id.button);
        button.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                ((TextView) MainActivity.this.findViewById(R.id.textView)).setText(editText.getText().toString());
            }
        });
    }
}


How to check if the EditText is empty?

Get the text from EditText and check if its length is zero. If its length is zero, the edittext will be empty.
 EditText editText=findViewById(R.id.editText);
String text=editText.getText().toString();
if (text.length()==0){
    //EditText is empty
    Toast.makeText(this, "Empty", Toast.LENGTH_SHORT).show();
}else{
    //EditText is not empty
    Toast.makeText(this, "Not Empty", Toast.LENGTH_SHORT).show();
}



You can also check if the text is equal to empty String like I did in the examples above.

 if ("".equals(text)){
    //EditText is empty
    Toast.makeText(this, "Empty", Toast.LENGTH_SHORT).show();
}else{
    //EditText is not empty
    Toast.makeText(this, "Not Empty", Toast.LENGTH_SHORT).show();
}
