Question

I am creating a simple quiz app and I need when users put their name in the EditText pop up a Toast message said "GoodLuck"+ Name.Could someone help on this? Here is my code: Thanks a lot!

MainActivity.java

 public class MainActivity extends AppCompatActivity {

        String Name;
        int score = 0;
        Button submitButton;
        Button resetButton;

        @Override
        protected void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.activity_main);

            //user input name
             final EditText nameField = (EditText)findViewById(R.id.nameField);
              Name = nameField.getText().toString();

            //submitButton shows user score
            submitButton = (Button) findViewById(R.id.submitButton);
            submitButton.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {
                    submitButton.setText("Your score is:" + score);
                }
            });
            //resetButton reset score to 0
            resetButton = (Button) findViewById(R.id.resetButton);
            resetButton.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {
                    submitButton.setText((String.valueOf(0)));
                }
            });
        }

activity_main.xml

 <EditText
            android:id="@+id/nameField"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:fontFamily="sans-serif-light"
            android:inputType="text"
            android:hint="Name"
            android:textColor="#EF6C00"
            android:textSize="15sp"/>

Immediately after they enter name or after submit button is clicked? — Shiv Buyya, Jul 12 '16 at 10:03
How to know if the user have finish writing the name. At least there should be a button to mark the "Finish" — Dehan Wjiesekara, Jul 12 '16 at 10:08
I suggest you to keep one button to update Name. otherwise it is not possible to know whether user completed entering name. — Shiv Buyya, Jul 12 '16 at 10:10

User should press Enter button after finsihed typing his name.

editText.setOnKeyListener(new OnKeyListener() {

            @Override
            public boolean onKey(View v, int keyCode, KeyEvent event)
            {
                if (event.getAction() == KeyEvent.ACTION_DOWN
                        && event.getKeyCode() ==       KeyEvent.KEYCODE_ENTER) 
                {
                   Toast.makeText(getApplicationContext(), "Good Luck:"+editText.getText().toString(), Toast.LENGTH_SHORT).show();    
                    return false;
                } 

            return false;
        }
    });

If you dont want to force user to press Enter button. Then use one button to updte name. Once user click on the button you can popup Toast.

if you press enter key then it will go to next line of that edittext... dont it? — gaurang, Jul 12 '16 at 10:52
No if use this android:singleLine="true" it will not go to next line. — Shiv Buyya, Jul 12 '16 at 11:33
