[android] EditText request focus

I am designing a login page as:

UserName:  .....

Password:  .....

     LoginButton

When the activity starts, I want the focus to go to "UserName" textbox and the keyboard to appear.

I am using the following code:

    boolean checkFocus=user.requestFocus();
    Log.i("CheckFocus", ""+checkFocus);
    if(checkFocus==true)
    {
    InputMethodManager mgr = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
    mgr.showSoftInput(user, InputMethodManager.SHOW_IMPLICIT);
    }

I don't understand where to write this code to make the keyboard appear when the activity starts and focus is on the "UserName" editText box. Can anyone please guide me?

Yes, I got the answer.. just simply edit the manifest file as:

        <activity android:name=".MainActivity"
        android:label="@string/app_name"
        android:windowSoftInputMode="stateAlwaysVisible" />

and set EditText.requestFocus() in onCreate()..

Thanks..

youredittext.requestFocus() call it from activity

oncreate();

and use the above code there

It has worked for me as follows.

ed1.requestFocus();

            return; //Faça um return para retornar o foco

edittext.requestFocus() works for me in my Activity and Fragment

>>you can write your code like

  if (TextUtils.isEmpty(username)) {
            editTextUserName.setError("Please enter username");
            editTextUserName.requestFocus();
            return;
        }

        if (TextUtils.isEmpty(password)) {
            editTextPassword.setError("Enter a password");
            editTextPassword.requestFocus();
            return;
        }
