代码如下：
Cursor cursor = mydatabasehelper.fetchAllData1(type);
if(cursor != null){     
while (cursor.moveToNext()) { 
String name = cursor.getString(cursor.getColumnIndex("type")); 
Log.v("info", "类型是 " + name ); 


if (cur != null && name.equals("发送")) {                                        //1213
System.out.println("发送(green)++++++++++++");
simpleadapter = new SimpleCursorAdapter(this,R.layout.list_say_he_item,cur, 
new String[] {"type","det","tim" }, new int[] {R.id.neirong,R.id.single_text,R.id.tim2});    
}else{
System.out.println("接收(white)————————");
simpleadapter = new SimpleCursorAdapter(this,R.layout.singletext,cur, 
new String[] {"type","det","tim" }, new int[] {R.id.send_receive_text,R.id.single_text,R.id.tim2});
}
setListAdapter(simpleadapter);
simpleadapter.notifyDataSetChanged();
} 
cursor.close(); 
} 
得到结果老是只显示一种layout，如何在会话中根据name的值，显示不同layout,求大神帮忙
