I am having Multiple Strings, that are coming dynamically, I want to set these strings as Id of the EditText Fields in my Form. How can I do that, can you please help me?

For Ex: If I am having id "title", I want to set this title as id of the EditText Field, so that when I want to access the value of this field, I can access it like findviewById(title).

Please help me here...

Thank you so much in advance.

You can get the id by reflection. For example, if you have a view in xml which has this id: @+id/select_time Then you can get the int value in Rclass by this way:

String idStr = "select_time";
    //com.example.appandroidtest is your app's package name
    Class<?> clz = com.example.appandroidtest.R.id.class;
    try {
        int viewId = (int) clz.getField(idStr).get(null);
    } catch (Exception e) {
        e.printStackTrace();
    }

  • Is there any way in that I can add these strings as id in xml file dynamically？--- I think this is impossible, since you cannot modify any resource file in runtime. – hanswim May 15 '15 at 08:06
