When EditText null value, EditText but can not get the focus and the soft keyboard popups

EditText no value is to ask how to get the focus of the pop-up soft keyboard?

As the registration page first loads do not want to start a soft keyboard and focus! So I'm all EditText parent added

 
android: focusable = "true" 
android: focusableInTouchMode = "true" 

Do not get the focus and the soft keyboard pop up to load.

I hope to fill in the following information to determine the value of each EditText, in the absence of input values ​​EditText to give it focus soft keyboard pops up!
The following is my approach:

 
public class Reg extends Activity implements OnClickListener {
private Dialog dialog; 
String mc ;/ / Name 
String u ;/ / username 

EditText u_mingcheng, u_user; 

protected void onCreate (Bundle savedInstanceState) {
/ / TODO Auto-generated method stub 
super.onCreate (savedInstanceState); 
setContentView (R.layout.reg); 
/ / 
u_mingcheng = (EditText) findViewById (R.id.u_mingcheng); 
u_user = (EditText) findViewById (R.id.u_user); 

 
private void reg () {
mc = u_mingcheng.getText () toString ();. 
u = u_user.getText () toString ();. 


if (u_mingcheng.length () == 0 | | u_user.length () == 0) {

if (u_mingcheng.length () == 0) {
u_mingcheng.requestFocus () ;/ / get the focus 
u_mingcheng.requestFocusFromTouch (); 
System.out.println ("1"); 
} 

return; 

} 

These are part of the code!

System.out.println ("1"); has executed, but u_mingcheng get less focus and play the keyboard.<-! Main posts under Banner (D4) -><-! Posts under the main text (D5) ->

Obtain input focus and pop should not the same thing and you call this method in which it is placed on the main thread
Reply:
Yes! In the main UI thread inside.

UI painting is not completed before obtaining the focus is invalid, so do not take reg on oncreate method inside or delayed a few seconds to perform.
