Question

Im a beginner in android and need your advice:

1. The app is about to send a message (sms or email) using two radio buttons (SMS or Email).

2. When initiating, the SMS radio button will be checked and the EditText for the contact/receiver is on android:inputType="phone"

3. If i click on the EMAIL radio button i would like the EditText to be changed to android:inputType="textEmailAddress"

how can i do this from the MainActivity.java?

Answer 1

As the others have said the function to change the input type would be the setInputType function, how you could use it would be a couple of ways.

1. Create a button listener from the code.

   OR use the onClick option in your element. <– How I would do it personally and shown below

I.E.

`<RadioButton android:layout_width="wrap_content"
         android:layout_height="wrap_content"
         android:onClick="setInputTypeToSMS"
         android:text="SMS">`
`<RadioButton android:layout_width="wrap_content"
         android:layout_height="wrap_content"
         android:onClick="setInputTypeToEmail"
         android:text="EMAIL">`

then in your main activity

public class SomeActivity extends Activity{
    private EditText editText;
    public void onCreate(Bundle savedInstanceState) 
    {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        editText = (EditText)findViewById(R.id.editText);

    }
    public void setInputTypeToEmail(View view)
    {
       editText.setInputType(InputType.TYPE_TEXT_VARIATION_EMAIL_ADDRESS);
    }
    public void setInputTypeToSMS(View view)
    {
       editText.setInputType(InputType.TYPE_CLASS_PHONE);
    }
}
