title: Android searchview remove hint padding
body: <p>I'm working in my app and have a searchview inside toolbar but the hint has a small padding after the cursor.</p>
  
  <p>How can I remove the padding?</p>
  
  <p>Here is my searchview:</p>
  
  <p><a href="https://i.stack.imgur.com/bY8Ue.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/bY8Ue.png" alt="searchview"></a></p>
  
  <p>and I would like that:</p>
  
  <p><a href="https://i.stack.imgur.com/xG3Bs.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/xG3Bs.png" alt="searchview with no padding"></a></p>
  
  <p>here is my onCreateOptionsMenu:</p>
  
  <pre><code>SearchManager searchManager=(SearchManager)getSystemService(Context.SEARCH_SERVICE);
      MenuItem item=menu.findItem(R.id.procura);
      Drawable drawable = menu.findItem(R.id.procura).getIcon();
      if (drawable != null) {
          drawable.mutate();
          drawable.setColorFilter(Color.BLACK, PorterDuff.Mode.SRC_ATOP);
      }
  
      searchView=(SearchView) MenuItemCompat.getActionView(item);
      searchView.setSearchableInfo(searchManager.getSearchableInfo(getComponentName()));
      searchView.setQueryHint(getResources().getString(R.string.app_hint));
  
      try {
          Field mDrawable = SearchView.class.getDeclaredField("mSearchHintIcon");
          mDrawable.setAccessible(true);
          Drawable drw = (Drawable) mDrawable.get(searchView);
          drw.setBounds(0, 0, 0, 0);
      } catch (Exception e) {
          e.printStackTrace();
      }
