I'm using recycleview in google cloud speech api. And I would like to put the strings in the recycleview into a single edit text. How do I move a string from a recycleview into a single text?

here is java code. if you know the answer, let me know.. I tried but it doesn't work. The editview doesn't show all of texts in reclycleview...

Answer 1

Create a TextView element outside of that recycle view. Then initialize it onCreate() method.

You need to extract text from that recycle view. I have no idea about that u hold data. Anyhow get a text from that. Then updateText using textView.setText(...) when that recycleText updated

Define TextView like this in mainActivity and initalize it in onCreate

static TextView recyText;

in

oncreate(){
   ....
   recyText=(TextView) findViewById(R.id.recyText);

}

the update it in below code segment

 @Override
     public void onBindViewHolder(ViewHolder holder, int position) {
         holder.text.setText(mResults.get(position));
         recyText.setText(recyText.getText()+ " " +mResults.get(position))

      }
