<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
   xmlns:tools="http://schemas.android.com/tools"
   android:layout_width="match_parent"
   android:layout_height="match_parent"

      editText = findViewById(R.id.editText);
      textView = findViewById(R.id.textView);
   }
   public void setText(View view){
      String newText = editText.getText().toString();
      textView.setText(newText);
      closeKeyBoard();
   }
   private void closeKeyBoard(){
      View view = this.getCurrentFocus();
      if (view != null){
         InputMethodManager imm = (InputMethodManager)
         getSystemService(Context.INPUT_METHOD_SERVICE);
