     lv_main.setAdapter(mDataAdapter);
-
-    popupMenuItemList.add("复制");
-    popupMenuItemList.add("删除");
-    popupMenuItemList.add("更多...");
+    popupMenuItemList.add(getString(R.string.copy));
+    popupMenuItemList.add(getString(R.string.delete));
+    popupMenuItemList.add(getString(R.string.share));
+    popupMenuItemList.add(getString(R.string.more));
     PopupList popupList = new PopupList();
     popupList.init(this, lv_main, popupMenuItemList, new PopupList.OnPopupListClickListener() {
         @Override
         public void onPopupListClick(View contextView, int contextPosition, int position) {
-            Toast.makeText(MainActivity.this, "您点击了第" + contextPosition + "个列表项的第" + position + "个菜单：" + popupMenuItemList.get(position),
-                    Toast.LENGTH_LONG).show();
+            Toast.makeText(MainActivity.this, contextPosition + "," + position, Toast.LENGTH_LONG).show();
         }
     });
+    ImageView indicator = new ImageView(this);
+    indicator.setImageResource(R.drawable.popuplist_default_arrow);
+    popupList.setIndicatorView(indicator);
+    popupList.setIndicatorSize(dp2px(16), dp2px(8));
