Activity 班级代码:

conversationList = (ListView)findViewById(android.R.id.list);
ConversationArrayAdapter conversationArrayAdapter=new  ConversationArrayAdapter(this, R.layout.conversation_list_item_format_left, conversationDetails);
conversationList.setAdapter(conversationArrayAdapter);
conversationList.setOnItemClickListener(new AdapterView.OnItemClickListener(){ 
    @Override
    public void onItemClick(AdapterView<?> arg0, View arg1, int position, long arg3) {
        Log.d("test","clicked");
    }
});

类中的getView函数Adapter:

if (v == null) {                                
    LayoutInflater vi = (LayoutInflater)ctx.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    if(leftSideMessageNumber.equals(m.getTo())) {
        v = vi.inflate(R.layout.conversation_list_item_format_left, null);
    } else {
        v = vi.inflate(R.layout.conversation_list_item_format_right, null);
    }
}

在充气时使用两个xmls有问题吗？

我正在尝试在ActiveRecord对象上调用一个方法,其中存在同名属性.这会导致SystemStackError: stack level too deep错误.

如何从方法中访问对象属性以进行修改？

def first_name

 return self.first_name.upper
