第三活动的捆绑商品为空

Question

hi im using bundle to pass a string from my MainActivity to my second activity which is sub genre. but i also need the same string in my third activity.

i use my code like this in my main acitvity

     Bundle getGenre_Bundle = new Bundle();
            if (genre.equals(selector.Crime)) {
             Intent i = new Intent(getBaseContext(),Crime.class);
                getGenre_Bundle.putString("crime",selector.Crime);
                i.putExtras(getGenre_Bundle);
                startActivity(i);

then i call it in my second Activity using

 Bundle p = getIntent().getExtras();
    Genre = p.getString("crime");

this works great but if i try to call it on my third activity it returns an error in my log that my firebase child(Genre)cant be null .

Ive fixed the problem by making a new bundle in my second activity that recollects the String to pass to my third activity. but it seams a bit of a messy way of doing it. is there an easier/better way to pass strings to any activity?

Answer 1

You can fetch entire bundle from your previous activity in second activity and simply set in intent with putExtras()

Bundle old = getIntent().getExtras();
Intent thirdActivity = new Intent(this,thirdActivity.class);
thirdActivity.putExtras(p);
