Question

I’m making an app that stores results in a multiple textviews,
First, I need to get the views, they are 20 views named result 1, …. result 20.
how can i get them to an array of textview.
I found this method but it’s too long

TextView [] results = {(TextView)findViewById (R.id.result1),
            (TextView)findViewById (R.id.result2),(TextView)findViewById (R.id.result3),
            (TextView)findViewById (R.id.result4),(TextView)findViewById (R.id.result5),
            (TextView)findViewById (R.id.result6).....};

thank you for help

How you started is correct, now think about putting that repetitive code in a cycle.

For example design a method that will take as the input an array of your TextView resources, and using a “for” cycle find that view by corresponding id.

private TextView[] initTextViews(int[] ids){

        TextView[] collection = new TextView[ids.length];

        for(int i=0; i<ids.length; i++){
            TextView currentTextView = (TextView)findViewById(ids[i]);
            collection[i]=currentTextView;
        }

        return collection;
}

And then you use it like this:

// Your TextViews ids
int[] ids={R.id.result1, R.id.result2, R.id.result3};

// The resulting array
TextView[] textViews=initTextViews(ids);
