title: Return item name from ExpandableListView after onClick as String
body: <p>So I am trying to get the name of the child item as a string so that I can add it to other data that I collected and insert it in to a database but this method does not work, all I get is the name of the parent.</p>
  
  <pre><code> exp_list.setOnChildClickListener(new ExpandableListView.OnChildClickListener() {
          @Override
          public boolean onChildClick(ExpandableListView parent, View v, int groupPosition, int childPosition, long id) {
              TextView the = (TextView) findViewById(R.id.child_txt);
              String tx = the.getText().toString();
              Toast.makeText(getBaseContext(), tx + " Child Clicked", Toast.LENGTH_SHORT).show();
  
              // Store value in sharedPreferences();
  
              Intent l = new Intent(CategoryActivity.this, AddRecipeActivity.class);
              startActivity(l);
              return false;
          }
      });
  </code></pre>
