android listview 里面view的监听问题
部分listview布局：
<ListView
android:id="@+id/hehelistview"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:cacheColorHint="#00000000"
android:descendantFocusability="blocksDescendants"
android:divider="#00000000"
android:listSelector="#00000000" />
部分item布局：
iamgebutton：
<ImageView
android:id="@+id/hehelistview_item_imgbutton"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:focusable="false"
android:padding="2dp"
android:scaleType="fitXY"
android:src="@drawable/usermorenpic" />
button:
<Button
android:id="@+id/hehelistview_item_button"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="@drawable/messagebtnpic"
android:focusable="false"
android:gravity="center"
android:text="消息"
android:textColor="#b63401" />

1、监听listview的itemclick（楼主实现办法：在activity监听）
2、在myadapter（继承baseadapter）里面监听view（imagebutton和button的onclick事件） （楼主实现办法：getview里面监听mViewHolder的两个按钮的onclick）
运行效果：
1、如果listview有1条数据。运行结果毫无问题。都能正确监听。
2、如果listview有多条数据，第1条数据的imgbutton和button监听有问题。（比如点击5次imgbutton，这时不会触发imgbutton的onclick的。再紧接着点击第2条数据的itemclick，奇特事件发生了，先触发itemclick事件，然后触发5次imgbutton的onclick事件。）
到这里，楼主就不懂了。（楼主就15个财富值。。。高手别吝啬吧。求指导）

你好 、你说的那几个属性我没全加。但是我加上之后问题依然存在 。总感觉是itemclick阻塞了onclick 。着急啊
那可以把你的代码片段发过来看看吗，主要是ListView的Adapter(yq135314@163.com)
