android - 从对话框调用 onCreateDialog()

Question

我从 SherlockFragmentActivity 创建了一个 SherlockDialogFragment..

这是我到目前为止所做的::

DatePickerFragment newFragment = DatePickerFragment.newInstance(ReportDisplayActivity.this);
newFragment.show(getSupportFragmentManager(), "dialog");

SherlockDialogFragment

public class DatePickerFragment extends SherlockDialogFragment implements android.view.View.OnClickListener
{

    private Button btnOk;
    private TextView txtFromDate;
    private TextView txtToDate;
    private int setFromYear;
    private int setFromMonth;
    private int setFromDay;
    private int setToYear;
    private int setToMonth;
    private int setToDay;

    private final static int DIALOG_FROM_DATE_PICKER = 0;
    private final static int DIALOG_TO_DATE_PICKER = 1;
    private static Context context;

    public DatePickerFragment() {
    }

    public static DatePickerFragment newInstance(Context ctx) {
        DatePickerFragment frag = new DatePickerFragment();
        Bundle args = new Bundle();
        //args.putInt("title", title);
        frag.setArguments(args);
        context=ctx;
        return frag;
    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,Bundle savedInstanceState) 
    {
        View  rootView = inflater.inflate(R.layout.temp, container, false);
        txtFromDate=(TextView)rootView.findViewById(R.id.dialog_fromDate);
        txtToDate=(TextView)rootView.findViewById(R.id.dialog_toDate);
        btnOk=(Button)rootView.findViewById(R.id.btn_ok);
        btnOk.setOnClickListener(this);
        txtFromDate.setOnClickListener(this);
        txtToDate.setOnClickListener(this);

        Calendar today = Calendar.getInstance();
        setFromYear = today.get(Calendar.YEAR);
        setFromMonth = today.get(Calendar.MONDAY);
        setFromDay = today.get(Calendar.DAY_OF_MONTH);

        setToYear = today.get(Calendar.YEAR);
        setToMonth = today.get(Calendar.MONDAY);
        setToDay = today.get(Calendar.DAY_OF_MONTH);

        return rootView;
    }

    //@Override
    protected Dialog onCreateDialog(int id)
    {
        switch(id)
        {
        case DIALOG_FROM_DATE_PICKER:
            return new DatePickerDialog(context, mDateFromSetListener, setFromYear, setFromMonth, setFromDay);

        case DIALOG_TO_DATE_PICKER:
            return new DatePickerDialog(context, mDateToSetListener, setToYear, setToMonth, setToDay);
        }
        return null;
    }

    private DatePickerDialog.OnDateSetListener mDateFromSetListener = new DatePickerDialog.OnDateSetListener(){
        @Override
        public void onDateSet(android.widget.DatePicker view, int year, int month, int day) {
            setFromYear = year;
            setFromMonth = month;
            setFromDay = day;
            //returnDate();
            txtFromDate.setText(setFromDay+("-")+setFromMonth+("-")+setFromYear);
        }
    };

    private DatePickerDialog.OnDateSetListener mDateToSetListener = new DatePickerDialog.OnDateSetListener(){
        @Override
        public void onDateSet(android.widget.DatePicker view, int year, int month, int day) {
            setToYear = year;
            setToMonth = month;
            setToDay = day;
            txtFromDate.setText(setToDay+("-")+setToMonth+("-")+setToYear);
            //returnDate();
        }
    };
    public void onClick(View v) 
    {
        switch (v.getId()) {
        case R.id.btn_ok:
            Toast.makeText(context,"Button ok",Toast.LENGTH_SHORT).show();
            break;

        case R.id.dialog_fromDate :
            Toast.makeText(context,"From Date",Toast.LENGTH_SHORT).show();
            ((Activity) context).showDialog(DIALOG_FROM_DATE_PICKER); 
            break;
        case R.id.dialog_toDate :
            Toast.makeText(context,"To Date",Toast.LENGTH_SHORT).show();
            ((Activity) context).showDialog(DIALOG_TO_DATE_PICKER); 
            break;
        default:
            break;
        }

    }
}

我无法从 SherlockDialogFragment 打开 Datepicker 对话框。我无法在我的实现中找到问题所在。

如果我使用 Activity 而不是 SherlockDialogFragment 那么它工作正常。

我可以像这样弹出对话框，但是当我点击文本“从日期选择”或“选择到日期”(从我想显示日期选择器对话框的地方)时，日期选择器对话框不显示。

Answer 1

这是解决方案，

主要 Activity

public class MainActivity extends SherlockFragmentActivity 
{
    @Override
    protected void onCreate(Bundle savedInstanceState) 
    {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        FragmentTransaction ft = getSupportFragmentManager().beginTransaction();
        DatePickerFragment newFragment = DatePickerFragment.newInstance(this);
        newFragment.show(ft, "dialog");
    }
}

主.xml

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".MainActivity" >

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_centerHorizontal="true"
        android:layout_centerVertical="true"
        android:text="@string/hello_world" />

</RelativeLayout>

日期选择器 fragment

public class DatePickerFragment extends SherlockDialogFragment implements android.view.View.OnClickListener
{
    private final static int DIALOG_FROM_DATE_PICKER = 0;

style.xml 与您的代码相同。

我在您的代码中发现您是通过以下语句获取月份 setFromMonth = today.get(Calendar.MONDAY); 或 setToMonth = today.get(Calendar.MONDAY); 。我相信你做错了。我还通过编写一个通用的 mDateSetListener 监听器来最小化您的代码。另请记住，Calendar.MONTH 对 1 月返回 0，因为它的索引以 0 开头。在将月份值设置为相应的 TextView 之前，我在监听器中添加了 +1。
