我有一个自定义 listView.xml 有一个 listView 作为。
<?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、2 个 TextView 和一个 RatingBar (item_list.XML),如下所示。
<?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"
android:layout_alignParentLeft="true"
android:layout_alignParentTop="true" >
<ImageView
android:id="@+id/img_searchBookCoverPhoto"
android:layout_width="70dp"
android:layout_height="100dp"
android:layout_margin="5dp"
android:background="@drawable/rounded_image_borders"
android:focusable="false"
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"
android:textColor="@color/White"
android:textSize="16sp" />
<TextView
android:id="@+id/txt_searchAutherName"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="@+id/txt_searchBookTitle"
android:layout_marginTop="2dp"
android:layout_toRightOf="@+id/img_searchBookCoverPhoto"
android:focusable="false"
android:text="By: Andrew J Newman"
android:textColor="@color/SkyBlue"
android:textSize="14sp" />
<RatingBar
android:id="@+id/searchRatingbar"
style="?android:attr/ratingBarStyleSmall"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="@+id/txt_searchAutherName"
android:layout_marginTop="12dp"
android:layout_toRightOf="@+id/img_searchBookCoverPhoto"
android:focusable="false"
android:isIndicator="false"
android:numStars="5"
android:rating="5"
android:stepSize="1" />
</RelativeLayout>
</RelativeLayout>
- 我的问题是我有一个 Listview 的点击事件,如下所示
但它不起作用,我真的很惊讶,为什么会这样
正如你所看到的,我也设置了这个
android:focusable="false"
对于我的自定义 listView 中的所有视图。
这里也是自定义适配器的代码。
