两个不同的 Listviews 合二为一 Activity，只有一个给出了正确的 ItemClicks

Question

我在一个 activity 上有两个列表视图，一切正常，但如果我想从列表视图 1 和列表视图 2 中获取点击的项目，我只能从列表视图 1 中获取项目

activity_smokes:

    <?xml version="1.0" encoding="utf-8"?>
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:id="@+id/scrollojt"
    android:fillViewport="true" >

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_gravity="center"
        android:layout_marginLeft="10dp"
        android:layout_marginRight="10dp"
        android:layout_marginBottom="10dp"
        android:layout_marginTop="10dp"
        >
        <ListView
            android:id="@+id/listView1"
            android:layout_width="0px"
            android:layout_height="wrap_content"
            android:layout_marginTop="100dp"
            android:layout_weight=".5">
        </ListView>

        <ListView
            android:layout_width="0px"
            android:layout_height="wrap_content"
            android:id="@+id/listView"
            android:layout_alignParentTop="true"
            android:layout_alignParentEnd="true"
            android:layout_weight=".50"
            android:layout_marginTop="100dp"
            />

    </LinearLayout>
</ScrollView>

编辑： 我更新了代码，它现在对我有用了！

Answer 1

原因是您使用不同的数据集来填充您的列表视图，但在 onItemClick 中，尽管您从任何列表视图中选择一个项目，但您只从一个数据集中获取数据。

第一个列表使用 "CustomListViewValuesArrCT" 数据集

ListView listCT = (ListView)findViewById(R.id.listView);
  adapterCT=new CustomAdapter(CustomListView, CustomListViewValuesArrCT,res);
  listCT.setAdapter( adapterCT);

第二个列表使用 "CustomListViewValuesArr" 数据集

 ListView list= ( ListView )findViewById( R.id.listView1 ); 
    adapter=new CustomAdapter( CustomListView, CustomListViewValuesArr,res );
    list.setAdapter(adapter);

但是仅从任一列表项选择中的 "CustomListViewValuesArr" 获取数据。

      public void onItemClick(int mPosition)
        {
           // You are fetching value from "CustomListViewValuesArr" only 
            ListModel tempValues = ( ListModel ) CustomListViewValuesArr.get(mPosition); 

    .....
        }

您需要修复您的流程，以便在单击列表项时从您为该特定列表设置适配器的数据集中获取数据。
