我有一个自定义listView.xml有一个listView as。onItemClicklistner（）;不工作自定义listView在android
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@null" >
<ListView
android:id="@+id/searchList"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_below="@+id/txtSearchFor"
android:background="@color/Black" >
</ListView>
</RelativeLayout>
此列表视图包含一个ImageView的，2个TextViews和的RatingBar（item_list.XML）如下面给出的。
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<RelativeLayout
android:id="@+id/rel_SearchLayout01"
android:layout_width="match_parent"
android:layout_height="wrap_content"

<ImageView

android:layout_margin="5dp"
android:background="@drawable/rounded_image_borders"

android:src="@drawable/book1" />
<TextView
android:id="@+id/txt_searchBookTitle"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignTop="@+id/img_searchBookCoverPhoto"
android:layout_marginTop="10dp"
android:layout_toRightOf="@+id/img_searchBookCoverPhoto"
android:focusable="false"
android:text="The Basic Doctrine Of Islam"

<TextView

android:layout_height="wrap_content"

android:focusable="false"
android:isIndicator="false"
android:numStars="5"
android:rating="5"
android:stepSize="1" />
</RelativeLayout>
</RelativeLayout>
- 我的问题是，我有列表视图click事件如下图所示
，但其没有工作，我真的感到惊讶，为什么发生这种情况
正如你所看到的，我也设置了这个
android:focusable="false"
适用于我的自定义listView中的所有视图。
这里也是自定义适配器的代码。

你也应该给：机器人：focusableInTouchMode =“假” –
，你可以设置：listView.setChoiceMode（ListView.CHOICE_MODE_SINGLE） ;对于listView或列表视图内的视图 –
？ –
