Question

I want to insert a for statement that increments and displays Strings on a TextView when the user clicks the Next button. But when i press the button it displays “3”. Can anyone point out where im going wrong. Thanx

public void onClick(View v) {
    // TODO Auto-generated method stub
     switch(v.getId()){
     case R.id.one:
         break;
        case R.id.Next:
            final CharSequence[] items = {"Test", "Test1", "Test3", "Test4"};
            for(i=0; i<items.length; i++){
            String s = (String)items[i];
            info.setText(s);

    }

    break;

}

}

Your for loop loops until the last value each time you click the Button. If you just want to show the next string:

// field 
int value = 0;

public void onClick(View v) {
    // TODO Auto-generated method stub
     switch(v.getId()){
     case R.id.one:
         break;
        case R.id.Next:
            final CharSequence[] items = {"Test", "Test1", "Test3", "Test4"};            
            if (value < items.length) {
               String s = (String)items[value];
               info.setText(s);
               value++;   
            } 
    }

    break;

}
