##ClickTracker

easy to hook onClick event.

###USAGE

step1. Write the onClick event code as usual

public void onClick(View view) {
    Map map = new HashMap();
    switch (view.getId()) {
      case R.id.btn_hook1:
        map.put("巴", "掌");
        map.put("菜", "比");
        break;
      case R.id.btn_hook2:
        map.put("TF-Boys", "嘿嘿嘿");
        map.put("id", "111");
        break;
    }
    view.setTag(R.id.id_hook, map);
}

If you want to track some data about this click event, you can new a map and put some data in it, at last call setTag().

step2. customize HookListener

public static class HookListener implements View.OnClickListener {

    private View.OnClickListener mOriginalListener;

    public HookListener(View.OnClickListener originalListener) {
      mOriginalListener = originalListener;
    }

    @Override public void onClick(View v) {
      mOriginalListener.onClick(v);
      StringBuilder sb = new StringBuilder();
      sb.append("hook succeed.\n");
      Object obj = v.getTag(R.id.id_hook);
      if (obj instanceof HashMap && !((Map) obj).isEmpty()) {
        for (Map.Entry<String, String> entry : ((Map<String, String>) obj).entrySet()) {
          sb.append("key => ")
              .append(entry.getKey())
              .append(" ")
              .append("value => ")
              .append(entry.getValue())
              .append("\n");
        }
      } else {
        sb.append("params => null\n");
      }

      Toast.makeText(v.getContext(), sb.toString(), Toast.LENGTH_LONG).show();
    }
}

In this class, you can call getTag to get the map which you transmit ever before and track!
