Question

我有listview。我用适配器填充它但它不可点击。我有检查列表视图不为空。我在Activity中有Listview人口代码它由DemoAdapter使用Another视图填充。

这是活动代码

 var listView = FindViewById<ListView>(Resource.Id.menuListRestaurent);
        DemoAdapter adapter = new DemoAdapter(this, mItems);
        listView.Adapter = new DemoAdapter(this, mItems);
        listView.ItemClick += (object sender, AdapterView.ItemClickEventArgs e) =>
        {
            var t = mItems[e.Position];
            int id = t.ProductId;
            var activity2 = new Intent(this, typeof(SingleProductDetailActivity));
            activity2.PutExtra("MyData", id);
            StartActivity(activity2);
        };

这是Listview

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:minWidth="25px"
android:minHeight="25px">
<ListView
    android:minWidth="25px"
    android:minHeight="25px"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:listSelector="@android:color/transparent"
    android:id="@+id/menuListRestaurent" />

        <TextView
            android:id="@+id/Text1"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:textColor="@color/blue"

      </LinearLayout>
    </TableLayout>

  ListView listview= (ListView) view.findViewById(R.id.ratingListViewId);
        final Adapter adapter = new Adapter(mItems,getApplicationContext());

 listview.setOnItemClickListener(new AdapterView.OnItemClickListener() {
            @Override
            public void onItemClick(final AdapterView<?> adapterView, View view, final int i, long l) {
