Question

我遇到了一个愚蠢的问题。我已经完成了相同的工作，但是第二次尝试时，onItemClick没有做任何事情。我现在重新重新复训了很多次，但似乎没有什么能吸引我的注意力。请看一下，让我知道出了什么问题所以这是我的设置。

活动：

 @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_promotionale);
        ListView mylist = (ListView) findViewById(R.id.lv_promotionale);
        mylist.setOnItemClickListener(new AdapterView.OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView<?> adapterView, View view, int position, long id) {
                Toast.makeText(PromotionaleActivity.this,"I touched an item at position"+Integer.toString(position),Toast.LENGTH_SHORT).show();
            }
        });

活动布局为：

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    android:paddingBottom="@dimen/activity_vertical_margin">

    <LinearLayout
        android:orientation="vertical"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent">

        <ListView
            android:layout_width="wrap_content"
            android:layout_height="370dp"
            android:id="@+id/lv_promotionale" />

        <LinearLayout
            android:orientation="horizontal"
            android:layout_width="fill_parent"
            android:layout_height="65dp"
            android:weightSum="1">

            <TextView
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:textAppearance="?android:attr/textAppearanceSmall"
                android:text="Some text here"
                android:id="@+id/textView"
                android:paddingLeft="15dp"
                android:paddingStart="15dp"
                android:paddingTop="15dp"
                android:paddingRight="0dp"
                android:paddingEnd="0dp"
                android:paddingBottom="0dp" />

        </LinearLayout>
    </LinearLayout>
</RelativeLayout>

修改这是我使用外部适配器加载listview数据的方法

 public void LoadListWithStuff(){
        SQLiteDatabase db = new myDbHelper(getApplicationContext()).getWritableDatabase();
        Cursor mCursor = db.rawQuery("select _id,data,numar,idclient,numeclient,tipclient,trimisa from cereri_mst order by data,numar desc" , null);
        idid.clear();
        idclient.clear();
        numeclient.clear();
        tipclient.clear();
        datacerere.clear();
        numarcerere.clear();
        trimisa.clear();

        if (mCursor.moveToFirst()) {
            do {
                idid.add(Integer.toString(mCursor.getInt(0)));
                datacerere.add(mCursor.getString(1));
                numarcerere.add(mCursor.getString(2));
                idclient.add(Integer.toString(mCursor.getInt(3)));
                numeclient.add(mCursor.getString(4));
                tipclient.add(mCursor.getString(5));
                trimisa.add(mCursor.getString(6));
            } while (mCursor.moveToNext());
        }
        DisplayCereriAdapter disadpt = new DisplayCereriAdapter(PromotionaleActivity.this,idid,idclient,
                numeclient, tipclient,datacerere,numarcerere,trimisa);

        ListView lv = (ListView) findViewById(R.id.lv_promotionale);
        lv.setAdapter(disadpt);
        mCursor.close();
        db.close();

    }

此外，我必须在此处说明列表视图已填充。我可以看到listView的内容。唯一的问题是我似乎无法捕获listview上的ItemClick和longClick事件......

为什么它不起作用????? 我在这里疯了...... 谢谢

我找到的解决方案是停止使用checkBox并将其替换为ImageView ...现在一切正常
