Question

我正在尝试为ListView创建一个BaseAdapter。问题是当我在其他LinearLayout中创建一个LinearLayout时，监听器OnItemClickListener不起作用。如果我将组件放在LinearLayout之外工作正常。

我怎么能这样做？

的ListView

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <ListView
        android:id="@+id/lvEntregasPendente"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:scrollbars="vertical"
        ></ListView>
</LinearLayout>

适配器XML

适配器

public class EntregaPendenteListAdapter extends BaseAdapter {
    private Context context;

活动

//listview
lvEntregasPendente = (ListView)view.findViewById(R.id.lvEntregasPendente);
lvEntregasPendente.setOnItemClickListener(this);

@Override
    public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
        Log.i("ITEM->", position + "");
    }

Answer 1

似乎你的CheckBox正在窃取焦点。尝试在其上设置这些属性：

android:focusable="false"
android:focusableInTouchMode="false"
android:clickable="false"

ListView with BaseAdapter和LinearLayout？
