Number Insertion in android application:

Sometimes while dealing with numbers, we don’t want to insert any string inside an number so, we premiliary define an EditText so we externally specify an EditText attribute as android:inputType=”number”  After specifying this attribute in the EditText, it will be used only to insert a number.

Step 1: Create a brand new android project.

Step 8: Inside the onCreate method of your MainActivity class, insert the following code:

String num=number.getText().toString();

Step 9: In the final step, you can use the String number to get the number inserted by the user.

Developer may check the number entered by the user against the number in his database via num String.

I would suggest you to take a button to insert the number from the user.

Insert the following code on your onCreate method inside the file:
