Question

I’m trying to find out if the user put something in the edit text.
It works but when I don’t enter anything it wont show; “Please enter your name”.
Also tried null instead of “” or ” ” didn’t work.

Any help?

    package com.grumbledorf.Hellotraining;

import android.app.Activity;
import android.content.Context;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.widget.Toast;

public class main extends Activity {

    EditText etName;
    Button btMake;


    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        etName = (EditText) findViewById(R.id.etName);
        btMake = (Button) findViewById(R.id.btPress);
        final Context context = getApplicationContext();
        final int duration = Toast.LENGTH_SHORT;

        btMake.setOnClickListener(new View.OnClickListener() {

            public void onClick(View v) {
                if(etName.getText().toString() == " "){

                    Toast toast = Toast.makeText(context, "Please enter your name", duration);
                    toast.show();
                }else{
                    String Henk = etName.getText().toString();
                    Toast toast = Toast.makeText(context, "Welcome, " +  Henk, duration);
                    toast.show();
                }

            }
        });



    }
}

Maybe I got it wrong but why do you suppose the default input is a " "

try this instead if(etName.getText().equals(""))
