Question

I am working on validation of two edit text fields in my login page and little change in my idea. I need to show textview above this field if the user left field e1 without entering text and goes to e2. Any help is appreciated.

Here is my code:

import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.EditText;
import android.widget.TextView;
import android.widget.Toast;

;
public class LoginActivity extends Activity {
    EditText usernameText;
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.loginpage);
        Button login = (Button) findViewById(R.id.loghomebutton);
        Button newuser = (Button) findViewById(R.id.lognewuserbutton);
        EditText usernameText = (EditText)this.findViewById(R.id.emaileditlog);
        EditText passwordText = (EditText)this.findViewById(R.id.pwdeditlog);


    login.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            // TODO Auto-generated method stub

            Intent myIntent = new Intent(v.getContext(),
                    SettingsActivity.class);
            startActivityForResult(myIntent, 0);
            overridePendingTransition(R.anim.fadeout, 0);
        }
    });
    newuser.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View v) {
            // TODO Auto-generated method stub
            Intent myIntent = new Intent(v.getContext(),
                    RegisterActivity.class);
            startActivityForResult(myIntent, 1);
            overridePendingTransition(R.anim.fadeout, 0);
        }
    });

}

}

in XML add a textview above the edittext.. set textviews android:visibility="GONE" then in java code do this..

if(editText.getText.toString().equals(" "))
                   {
                   TextView t = findViewById(.......)
                   t.setVisibility(View.VISIBLE);
                   t.setText("..............");
                   }
