ArrayAdapter<String> aryAdapter=new ArrayAdapter<String>(GetTaskList.this,R.layout.list_item,aryListTask);
在使用ArrayAdapter时使用自己写的R.layout.list_item布局容易出现:ArrayAdapter requires the resource ID to be a TextView 报错

R.layout.list_item.xml:
[java] view
plaincopyprint?
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
>
<TextView android:id="@+id/text1"
android:textSize="16sp"
android:textStyle="bold"
android:layout_width="fill_parent"
android:layout_height="wrap_content"/>
</LinearLayout>
而使用android.R.layout.simple_expandable_list_item_1布局则不会....
问题出在:
[java] view
plaincopyprint?
<?xml version="1.0" encoding="utf-8"?>
<TextView
xmlns:android=http://schemas.android.com/apk/res/android
android:layout_width="fill_parent"
android:layout_height="wrap_content" />
xmlns:android=http://schemas.android.com/apk/res/android 就是这句了....
添加到自己的TextView中就ok.
因为根节点必须是TextView
修改后的list_item.xml
[java] view
plaincopyprint?
<?xml version="1.0" encoding="utf-8"?>
<TextView
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/text1"
android:textSize="16sp"
android:textStyle="bold"
android:layout_width="fill_parent"
