How can i get last letter from edit text and put it in adapter

I have a delete button which deletes text in an EditText, and the value of the EditText is the item clicked in a RecyclerView. Now when I delete text from edit text it disappears from the adapter. Now how can I return it back to adapter after clicking on delete? 

@Override
public void onItemClick(View view, int position) {
    edit.setText(edit.getText() + adapter.getItem(position).toString().toUpperCase());
    edit.toString().toUpperCase();

    MediaPlayer  mediaPlayer2=MediaPlayer.create(Ridles.this,R.raw.zagonetkebutonklik);
    mediaPlayer2.start();
    suggestSource.remove(adapter.getItem(position));

    simpleArray = new String[suggestSource.size()];
    suggestSource.toArray(simpleArray);
    recyclerView = findViewById(R.id.recyclerView);
    int numberOfColumns = 5;
    recyclerView.setLayoutManager(new GridLayoutManager(this, numberOfColumns));
    adapter = new MyRecyclerViewAdapter(this, simpleArray);
    adapter.setClickListener(this);
    recyclerView.setAdapter(adapter);
    adapter.notifyItemRemoved(position);
    adapter.notifyItemChanged(position);
    adapter.notifyItemRangeChanged(position,suggestSource.size());
    lvl.setText("lvl: " +String.valueOf(curquestion));

}
public void obrisi(){
    String text=edit.getText().toString();
    if(text.length()>=1){
        edit.setText((text.substring(0, text.length() - 1)));
        edit.setVisibility(View.VISIBLE);

Use this to get the text from EditText:

String text = edit.getText().toString();

And get the last letter like this:

String lastL= text.substring(text.length() - 1);

Then set the value as follows:

edit.setText(lastL);
edit.setVisibility(View.VISIBLE);

You could just get the text from EditText:

String text = edit.getText().toString();

Then you can get the last character like this:

String lastString = text.substring(string.length() - 1);
