Android Java While loop in Handler not executing

Question

I have 6 string to show in a textview in order. But some of the strings are empty and I want my program to detect empty strings, wait 1 sec for each empty string detection and then continue to next text. I tried to do it with using Handler and while codes but I failed, any help would be appreciated.

TextView Textview1; 
int str[] = {R.string.str1,R.string.str2,R.string.str3,R.string.str4,R.string.str5,R.string.str6};
int CurrentText = 0;    
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    Textview1 = (TextView)findViewById(R.id.textview1);
    Button button = (Button)findViewById(R.id.button);
    button.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {
            // TODO Auto-generated method stub
            Textview1.setText(str[CurrentText]);
            String crnt = (String) getText(str[CurrentText]);
            CurrentText++;              

            if(crnt.equals("empty")){                   
                Handler loop = new Handler();
                loop.postDelayed(new Runnable() {

                    @Override
                    public void run() {
                        // TODO Auto-generated method stub                          
                        String crnt2 = (String) getText(str[CurrentText]);
                        while(crnt2.equals("empty")){                               
                            CurrentText++;
                            Textview1.setText(str[CurrentText]);
                            crnt2 = (String) getText(str[CurrentText]);                             
                        }                           
                    }
                }, 1000);
            }

                    }else{
                        //Çalışmayı durdurmak için de aşağıdaki kod kullanılabilir:
