i had a similar problem with the editText, which gained focus since the activity was started. this problem i fixed easily like this:
you add this piece of code into the layout that contains the editText in xml:
    android:id="@+id/linearlayout" 
    android:focusableInTouchMode="true"
dont forget the android:id, without it i've got an error.
the other problem i had with the editText is that once it gain the first focus, the focus never disappeared. this is a piece of my code in java, it has an editText and a button that captures the text in the editText:
    editText=(EditText) findViewById(R.id.et1);
    tvhome= (TextView)findViewById(R.id.tv_home);
    etBtn= (Button) findViewById(R.id.btn_homeadd);
    etBtn.setOnClickListener(new View.OnClickListener() 
    {   
        @Override
        public void onClick(View v)
        {
            tvhome.setText( editText.getText().toString() );
            //** this code is for hiding the keyboard after pressing the button
            View view = Settings.this.getCurrentFocus();
            if (view != null) 
            {  
                InputMethodManager imm = (InputMethodManager)getSystemService(Context.INPUT_METHOD_SERVICE);
                imm.hideSoftInputFromWindow(view.getWindowToken(), 0);
            }
            //**
            editText.getText().clear();//clears the text
            editText.setFocusable(false);//disables the focus of the editText 
            Log.i("onCreate().Button.onClickListener()", "et.isfocused= "+editText.isFocused());
        }
    });
    editText.setOnClickListener(new View.OnClickListener() 
    {
        @Override
        public void onClick(View v) 
        {
            if(v.getId() == R.id.et1)
            {
                v.setFocusableInTouchMode(true);// when the editText is clicked it will gain focus again
                //** this code is for enabling the keyboard at the first click on the editText
                if(v.isFocused())//the code is optional, because at the second click the keyboard shows by itself
                {
                    InputMethodManager imm = (InputMethodManager)getSystemService(Context.INPUT_METHOD_SERVICE);
                    imm.showSoftInput(v, InputMethodManager.SHOW_IMPLICIT);
                }
                //**
                Log.i("onCreate().EditText.onClickListener()", "et.isfocused= "+v.isFocused());
            }
            else
                Log.i("onCreate().EditText.onClickListener()", "the listener did'nt consume the event");
        }
    });
hope it will help to some of you!
