Question

i have created the login screen but i am unable to verify the data in the edit box..
i have tried for simple verification using following function that checks whether the username and password are same..

protected boolean isValid(String string1,String string2) {

if(string1.equals(string2))
return true;
else
return false;

}

but it is not working properly…

You have to specify EditText widget of android in you layout:

put this in your xml layout:

<EditText
android:id="@+id/username"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
/>

<Button
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="Verify"
android:onClick="isValid"
/>

now in you activity enter validation code:

public void isValid(View view){//signature is mandated

String validUsername="username";
EditText username=(EditText) findViewById(R.id.username);

if(username.getText.toString().equals(validUsername)){
//Username is valid perform you logic here.
}

}
