有了这段代码
final ListView lw = (ListView) findViewById( R.id.book_list );
lw.setVisibility(View.VISIBLE);
ListView listBookView = (ListView) findViewById( R.id.book_list );
ArrayList<HashMap<String, Object>> my_list = new ArrayList<HashMap<String, Object>>();
for ( int x=0; x< book_list.size(); x++)
{
String[] valori_book = book_list.get( x ).getObjVars();
HashMap<String, Object> map = new HashMap<String, Object>();
map.put("book", valori_book[ 0 ]);
map.put("descr", valori_book[ 1 ] );
my_list.add(map);
}
// ...
SimpleAdapter showMenu = new SimpleAdapter(this, my_list, R.layout.activity_book_booklistmask,
new String[] { "book" , "descr" }, new int[] {R.id.nome_quaderno, R.id.descrizione_quaderno});
listBookView.setAdapter(showMenu);
java.lang.IllegalStateException：android.widget.ListView不是可以通过此SimpleAdapter绑定的视图
logcat不会在我的项目中写入错误行，因此我不知道在哪里检查：/

最佳答案
从SimpleAdapter文档
实现Checkable的视图（例如CheckBox）。预期的绑定值是一个布尔值。
TextView。预期的绑定值是一个字符串，并调用setViewText（TextView，String）。
ImageView。预期的绑定值是资源ID或字符串，并调用setViewImage（ImageView，int）或setViewImage（ImageView，String）。
似乎将Object传递为映射对象与SimpleAdapter不兼容。更改对象类型，或创建自定义适配器（我建议稍后使用）
关于android - ListView不显示适配器，我们在Stack Overflow上找到一个类似的问题：https://stackoverflow.com/questions/6958696/
