Android betterpickers问题

Question

我正在使用betterspickers库。我试图实施calendardatepicker。它会打开选​​择器对话框，但是当我点击应用程序崩溃的几个月中的某一天时。 这是我的班级：

    public class AddOneActivity extends ActionBarActivity implements CalendarDatePickerDialog.OnDateSetListener {

        private static final String FRAG_TAG_DATE_PICKER = "fragment_date_picker_name";

        private TextView text;
        private Button button;


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_add_one);
        DateTime now = DateTime.now();

        text = (TextView) findViewById(R.id.textView);
        button = (Button) findViewById(R.id.button);

        text.setText(now.getDayOfMonth()+"."+now.getMonthOfYear()+"."+now.getYear());
        button.setText("Set Date");
        button.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                FragmentManager fm = getSupportFragmentManager();
                DateTime now = DateTime.now();
                CalendarDatePickerDialog calendarDatePickerDialog = CalendarDatePickerDialog
                        .newInstance(AddOneActivity.this, now.getYear(), now.getMonthOfYear() - 1,
                                now.getDayOfMonth());
                calendarDatePickerDialog.show(fm, FRAG_TAG_DATE_PICKER);
            }
        });
    }
    @Override
    public void onDateSet(CalendarDatePickerDialog dialog, int year, int monthOfYear, int dayOfMonth) {
        text.setText("Year: " + year + "\nMonth: " + monthOfYear + "\nDay: " + dayOfMonth);
    }

    @Override
    public void onResume() {
        // Example of reattaching to the fragment
        super.onResume();
        CalendarDatePickerDialog calendarDatePickerDialog = (CalendarDatePickerDialog) getSupportFragmentManager()
                .findFragmentByTag(FRAG_TAG_DATE_PICKER);
        if (calendarDatePickerDialog != null) {
            calendarDatePickerDialog.setOnDateSetListener(this);
        }
    }


}

你能帮我吗？

Answer 1

您是否尝试过使用

<uses-permission android:name="android.permission.VIBRATE" />

你的清单上有

吗？

我相信你忘了获得字符串转换值。

 dateValue.setText(getString(R.string.calendar_date_picker_result_values, year, monthOfYear, dayOfMonth));

其中字符串值为：

<string name="calendar_date_picker_result_values">Year: %1$s Month: %2$s Day: %3$s</string>
