android - 在 TabActivity 内的 ListView 上使用 OnItemClickListener

Question

我的 ListView 的 OnItemCliskListener 有一个愚蠢的问题。它在 XML 非常简单时运行良好，但在我提高其复杂性后，OnItemCliskListener 停止工作

换句话说，我有一个只有一个 TextView 的 ListView。但是，如果我将我的 ListView 变成一个更复杂的列表，其中包含其他 TextView、Icon 和 CheckBox，ClickListener 将停止工作。

如果我运行仅更改 XML 的完全相同的代码，OnItemCliskListener 将停止工作。如果你能帮助我，我将不胜感激

工作 ListView :

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent" android:orientation="vertical"
    android:layout_height="fill_parent">
    <TextView android:id="@+id/title"
        android:layout_height="wrap_content" android:layout_width="wrap_content"
        android:layout_toLeftOf="@+id/appCheck"
        android:layout_toRightOf="@+id/appIcon"
        android:textAppearance="?android:attr/textAppearanceLarge">
    </TextView>
</RelativeLayout>

不工作 ListView :

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent" android:orientation="vertical"
    android:layout_height="fill_parent">
    <ImageView android:src="@drawable/icon" android:id="@+id/appIcon"
        android:layout_width="30px" android:layout_height="40px"></ImageView>
    <CheckBox android:id="@+id/appCheck"
        android:layout_width="wrap_content" android:layout_height="wrap_content"
        android:layout_alignParentRight="true"></CheckBox>
    <TextView android:id="@+id/title"
        android:layout_height="wrap_content" android:layout_width="wrap_content"
        android:layout_toLeftOf="@+id/appCheck"
        android:layout_toRightOf="@+id/appIcon"
        android:textAppearance="?android:attr/textAppearanceLarge">
    </TextView>
    <TextView android:id="@+id/subtitle"
        android:layout_height="wrap_content" android:layout_width="wrap_content"
        android:layout_toLeftOf="@+id/appCheck"
        android:layout_toRightOf="@+id/appIcon" android:layout_below="@+id/title"
        android:textAppearance="?android:attr/textAppearanceSmall">
    </TextView>
</RelativeLayout>

我的 JAVA Activity :

public class MyTabsActivity extends TabActivity implements OnTabChangeListener {
private static final String LIST3_TAB_TAG = "List3";

private RelativeLayout layoutTab3;      
private MyArrayAdapter adapterListViewTab3;
private TabHost tabHost;

        @Override
        public void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.main);

            tabHost = getTabHost();
            tabHost.setOnTabChangedListener(this);
...
...
// ----------------- BUILD TAB3
            // That is my Tab of Running App
            layoutTab3 = (RelativeLayout) findViewById(R.id.running_app_relative_layout);
            // Fill my ListView of Running App
            ListView runningAppList = (ListView) findViewById(R.id.running_app_listview);
            List<String> list3Strings = new ArrayList<String>();
            list3Strings.add("Item 1");
            list3Strings.add("Item 2");
            list3Strings.add("Item 3");
            list3Strings.add("Item 

            adapterListViewTab3 = new MyArrayAdapter(this, android.R.layout.simple_list_item_1, list3Strings);
            runningAppList.setAdapter(adapterListViewTab3);
            // ????????????????????????????????????????????????????????????????????????????????????????????
            // >>>>>>>>>>>> THIS OnItemClickAdapter DOESN'T WORK !!!!! WHY ????????
            runningAppList.setOnItemClickListener(new OnItemClickListener() {
                @Override
                public void onItemClick(AdapterView<?> parent, View view,
                        int position, long id) {
                    Toast.makeText(MyTabsActivity.this, "EUREKA", Toast.LENGTH_SHORT).show();
                }
            });

...
// add Tab3
            TabSpec tab3 = tabHost.newTabSpec(LIST3_TAB_TAG).setIndicator(LIST3_TAB_TAG).setContent(new TabContentFactory() {
                public View createTabContent(String arg0) {
                    return layoutTab3;
                }
            });
            tabHost.addTab(tab3);
            layoutTab3.setVisibility(View.INVISIBLE);

}
}

我发现当自定义 ListView 包含可聚焦元素时，onListItemClick 将不起作用(我认为这是预期的行为)。所以我刚刚从自定义 View 中删除了焦点，它成功了。换句话说，我在我的 View 中添加了以下命令:

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