activity_main.xml中:

android:layout_height="match_parent"
android:background="#36D92E">
<!-- As the main content view, the view below consumes the entire
space available using match_parent in both dimensions. -->
<!-- android:layout_gravity="start" tells DrawerLayout to treat
this as a sliding drawer on the left side for left-to-right
languages and on the right side for right-to-left languages.
The drawer is given a fixed width in dp and extends the full height of
the container. A solid background is used for contrast
with the content view. -->
<ListView

我做错了什么?希望得到一些帮助。非常感谢。
答案 0 :(得分:0)
在您的项目列表布局文件中,将android:clickable="true"
更改为android:clickable="false"
并在android:focusable="false"
和ImageView
TextView
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"

>
<ImageView
android:id="@+id/ivOptionPic"
android:layout_width="50dp"
android:layout_height="50dp"
android:focusable="false"
android:clickable="false"/>
<TextView
