问题描述

我的应用程序跟踪餐厅服务器的转移销售,以帮助他们的预算。在显示过去变化的活动,我已经在ListView下创建一个RadioGroup中,使用户可以选择显示午餐,晚餐,或两者兼而有之。

My app keeps track of restaurant servers' shift sales to help them budget. In the activity that displays past shifts, I've created a RadioGroup under the ListView so the user can choose to display lunch, dinner, or both.

我在活动RadioGroup.onCheckedChangeListener实施,但onCheckedChanged不会被调用。我使用匿名内部类作为监听器,同样的结果也试过。

I've implemented in the activity RadioGroup.onCheckedChangeListener, but onCheckedChanged never gets called. I also tried using an anonymous inner class as listener, same result.

我试图从这个答案复制/修改code: http://stackoverflow.com/a/9595528 ...但是当我加入了 @覆盖的回调函数,Eclipse编译器给了我一个错误(而不是警告),该方法必须重写超类,并快速修复是消除覆盖。

I tried to copy/modify code from this answer: http://stackoverflow.com/a/9595528 ...but when I added the @Override to the callback function, the Eclipse compiler gave me an error (not warning) that the method must override a superclass, and the quick fix was to remove the override.

我是pretty确认签名的比赛,因为他们与Eclipse的自动完成制作并执行方法的设施。然后我跟着指示我的java编译器移动从1.5到1.6,并没有上述所列行为似乎变了。

I'm pretty sure the signatures are match, as they were made with Eclipse's autocomplete and implement methods facilities. I then followed instructions to move my java compiler from 1.5 to 1.6, and none of the above listed behavior seemed to change.

这里的code,我认为是相关的:

Here's the code I think is relevant:

public class DataActivity extends ListActivity implements OnCheckedChangeListener{
    RadioButton rbBoth;
    RadioButton rbDinnerOnly;
    RadioButton rbLunchOnly;

    @Override
    public void onCreate(Bundle savedInstanceState){
        super.onCreate(savedInstanceState);
        setContentView(R.layout.database);
        // ...
        final RadioGroup rgGroup = (RadioGroup)findViewById(R.id.DataRadioGroup);
        rbBoth = (RadioButton)findViewById(R.id.RadioBoth);
        rbDinnerOnly = (RadioButton)findViewById(R.id.RadioDinnerOnly);
        rbLunchOnly = (RadioButton)findViewById(R.id.RadioLunchOnly);
        rgGroup.setOnCheckedChangeListener(this);
        populateAllShifts();
    }

    // ...

    public void onCheckedChanged(RadioGroup group, int checkedId) {
        rbLunchOnly.setText("Click!");
        Toast.makeText(getApplicationContext(), "Lunch Only", Toast.LENGTH_LONG).show();
        if(group.getCheckedRadioButtonId() == R.id.RadioBoth){
            populateAllShifts();
            return;
        }
        if(group.getCheckedRadioButtonId() == R.id.RadioLunchOnly){
            populatLunchShifts();
            return;
        }
        if(group.getCheckedRadioButtonId() == R.id.RadioDinnerOnly){
            populateDinnerShifts();
            return;
        }
    }

    // ...

}

有在这一类自定义适配器一个ListView,但如果我的理解和我的XML是正确的,RadioGroup中应该是名单之外的:

There is a ListView in this class with a custom adapter, but if my understanding and my XML are correct, the RadioGroup should be outside of the list:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/llDataLayout"
    android:weightSum="5"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent" android:orientation="vertical">

    <ListView android:layout_weight="4"
        android:layout_width="fill_parent"
        android:id="@android:id/list"
        android:layout_height="wrap_content">
    </ListView>

    <RadioGroup 
        android:layout_weight="1"
        android:id="@+id/DataRadioGroup"
        android:orientation="horizontal"
        android:layout_height="wrap_content"
        android:layout_width="fill_parent">

        <RadioButton android:text="Lunch and Dinner"
            android:textSize="10dp"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:id="@+id/RadioBoth"/>
        <RadioButton android:text="Dinner Only"
            android:textSize="10dp"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:id="@+id/RadioDinnerOnly"/>
        <RadioButton android:text="Lunch Only"
            android:textSize="10dp"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:id="@+id/RadioLunchOnly"/>

    </RadioGroup>

</LinearLayout>

任何想法了吗?

推荐答案

发现问题,得到的答复是不是从我在我的问题给了信息可见。这个问题是多余的内容。

Found the problem, and the answer wasn't visible from the info I gave in my question. The problem was cruft.

这开始了我的第一个项目,并在笨拙的企图个月前解决数据库的问题,我已经extraneously以pretty中的onCreate大同小异code覆盖在onStart()和onRestart() ()。的onCreate随时间的变化,以及这些方法没有。一旦我删除它们时,code完美地工作。

This started as my first project, and in a ham-handed attempt to solve a database problem months ago, I had extraneously overridden onStart() and onRestart() with pretty much the same code in onCreate(). onCreate has changed over time, and those methods did not. Once I deleted them, the code worked perfectly.

我还没有显示在问题的方法。对不起!

I hadn't shown those methods in the question. Sorry!

谢谢大家对你的帮助!我现在应该怎么做?删除的问题?

Thanks everyone for your help! What should I do now? Delete the question?
