Spinner 不响应setOnItemSelectedListener事件

媒体盒子 2013-10-08 03:41:16

各位大神，此问题折磨了我一天了，求支招！
情况如下：
我在ViewFlow （一个开源的滚动页面框架，类似Viewpage）中加入了一个Spinner控件

spnSYDK = (Spinner)findViewById(R.id.spn_test1);

		ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,android.R.layout.simple_spinner_item, strChannelNumber);

		    adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);

		    spnSYDK.setAdapter(adapter);        

		    spnSYDK.setOnItemSelectedListener(new Spinner.OnItemSelectedListener(){

	            public void onItemSelected(AdapterView<?> arg0, View arg1, int arg2, long arg3) {

	                // TODO Auto-generated method stub

	                /* 将所选mySpinner 的值带入myTextView 中*/

	            	Log.d("test","onItemSelected arg2 = " + arg2);

	            }

	            public void onNothingSelected(AdapterView<?> arg0) {

	                // TODO Auto-generated method stub

	            	Log.d("test","onNothingSelected ");

	            }

	        });

但是无论我选择Spinner里面的哪一项都不触发onItemSelected事件，也就无法实现选择功能该page的布局如下

<?xml version="1.0" encoding="utf-8"?>

<LinearLayout

	xmlns:android="http://schemas.android.com/apk/res/android"

	android:layout_height="fill_parent"

	android:descendantFocusability="blocksDescendants"

	android:layout_width="fill_parent" android:orientation="vertical" android:weightSum="1">

    <TextView android:textAppearance="?android:attr/textAppearanceLarge" android:text="Sample Text" android:id="@+id/textView1" android:layout_gravity="top" android:layout_height="wrap_content" android:layout_width="fill_parent" android:gravity="center_horizontal"></TextView>

   <Spinner android:layout_height="wrap_content"

         android:layout_width="fill_parent" 

        android:id="@+id/spn_test1"/>

    <ListView android:id="@+id/listView1" android:layout_width="fill_parent" android:layout_height="fill_parent"></ListView>



</LinearLayout>

有用过ViewFlow 并且在里面使用过Spinner的同学支下招，我目前怀疑是ViewFlow把事件截取了。。。实在不行就得弃用ViewFlow了
