Question

我的抽屉布局中有一个列表视图，我想为每个项目设置setlistener，我为listView的每个元素读取了几个post和setFocusable，setclickiable，setfocusableInTouchMode为false但仍然无效。先谢谢你。这是我的代码：

targetItem.xml

<?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="48dp"
android:background="#ffffff"
android:focusable="true"
android:clickable="true"
>

 <!-- icon -->
 <ImageView
     android:id="@+id/item_icon"
     android:layout_width="20dp"
     android:layout_height="20dp"
     android:layout_alignParentRight="true"
     android:layout_marginLeft="8dp"
     android:layout_marginRight="18dp"
     android:layout_marginTop="25dp"
     android:clickable="false"
     android:focusable="false"
     android:focusableInTouchMode="false"
     />

<!-- title -->
<TextView
     android:id="@+id/item_title"
     android:layout_width="wrap_content"
     android:layout_height="wrap_content"
     android:layout_toLeftOf="@+id/item_icon"
     android:textSize="12dp"
     android:layout_marginTop="28dp"
     android:layout_marginRight="15dp"
     android:textColor="#000000"
     android:clickable="false"
    android:focusable="false"
    android:focusableInTouchMode="false"

      />

<TextView
     android:id="@+id/item_id"
     android:layout_width="wrap_content"
     android:layout_height="wrap_content"
     android:layout_toLeftOf="@+id/item_icon"
     android:textSize="12dp"
     android:layout_marginTop="28dp"
     android:layout_marginRight="15dp"
     android:textColor="#000000"
     android:visibility="gone"
     android:clickable="false"
    android:focusableInTouchMode="false"
    android:focusable="false"/>


</RelativeLayout>

activity_main.xml中

<android.support.v4.widget.DrawerLayout    xmlns:android="http://schemas.android.com/apk/res/android"

android:id="@+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#ffffff"
tools:context=".MainActivity" >

<!-- The navigation drawer -->

<ListView
    android:id="@+id/listview"
    android:layout_width="240dp"
    android:layout_height="match_parent"
    android:layout_gravity="end"
    android:background="#ffffff"
    android:choiceMode="singleChoice"
    android:clickable="true"
    android:divider="@android:color/transparent"
    android:dividerHeight="0dp"
    android:focusable="true"
    android:focusableInTouchMode="true" />

<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"
    tools:context=".MainActivity" >

         .

         .
   </RelativeLayout>

 </android.support.v4.widget.DrawerLayout>

Answer 1

问题在于这一行rowView.setOnClickListener。注册onClickListener会阻止onItemClik被解雇。摆脱它，它会工作。如果您想在列表项上设置额外的点击监听器，则必须在OnClickListener的子项上设置convertView，而不是在convertView本身设置android:descendantFocusability="blocksDescendants"并添加Marshal.from_bytes }到列表项xml

的根目录

onItemClickListener不起作用
