Question

我正在使用CWAC MergeAdapter - https://github.com/commonsguy/cwac-merge在ListView中添加两个数据适配器。像这样：

MergeAdapter mergeAdapter = new MergeAdapter();
mergeAdapter.addAdapter(yourFirstAdapter);
mergeAdapter.addAdapter(yourSecondAdapter);
list.setAdapter(mergeAdapter);

我还为ListView设置了一个项目点击监听器。但是我想要的是只有来自adapter1的数据才可以点击。我该如何实现呢。到目前为止我所拥有的是：

ListView list = (ListView) findViewById(R.id.lv);

RelativeLayout secondAdapterlistRowLayout = (RelativeLayout) findViewById(R.id.secondrow);

list.setOnItemClickListener(new AdapterView.OnItemClickListener() {
        @Override
        public void onItemClick(AdapterView<?> adapterView, View view, int position, long mallId) {
            //go to the shops view
            if (adapterView.equals(secondAdapterlistRowLayout)){
                //do nothing
            }
            else {
                Intent intent = new Intent(getActivity(), ShopActivity.class);
                intent.putExtra("MALL_ID", (int) mallId);
                startActivity(intent);
            }
        }

    });

XML - row2 - adapter2

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical" android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="#F0F0F0"
    android:clickable="false"
    android:id="@+id/secondrow">
    ....
</RelativeLayout>

基本上我想这样做：

list.setOnItemClickListener(new AdapterView.OnItemClickListener() {
        @Override
        public void onItemClick(AdapterView<?> adapterView, View view, int position, long mallId) {

         if(R.id.secondrow is clicked){ then start a new activity }

        }
      }

Answer 1

我找到的更简单的方法是获取被点击的资源名称，然后将其与行的资源名称（即secondrow）进行比较

list.setOnItemClickListener(new AdapterView.OnItemClickListener() {
        @Override
        public void onItemClick(AdapterView<?> adapterView, View view, int position, long mallId) {

         if (getResources().getResourceEntryName(view.getId()).equals("secondrow"){
                     //then do something
            }
        //otherwise do nothing
        }
      }

Answer 2

在适配器视图中，对项目使用setTag（）方法，并在点击listview任何项目时识别该标记。

在ListView中禁用单击一个数据适配器
