问题描述

我尝试创建一个带有按钮和显示日期的文本视图的简单活动。单击该按钮时，应显示 HijriDatePicker 对话框。我尝试使用 ummalqura-calendar 制作它，并通过对话框尝试使用 HijriDatePicker 创建对话框。

然而，经过多次尝试，它不起作用。有时当我单击按钮时活动会停止，有时它会崩溃。我已经尝试了很多失败的尝试。

和我的主要活动 java

public class MainActivity extends AppCompatActivity implements HijriDatePickerDialog.OnDateSetListener{
    TextView tvDate;
    TextView etDate;
    HijriDatePickerDialog.OnDateSetListener setListener;

    public MainActivity() {

    }

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        tvDate = findViewById(R.id.tv_date);
        etDate = findViewById(R.id.et_date);


        tvDate.setonClickListener(v -> {
            UmmalquraCalendar Now = new UmmalquraCalendar();
            HijriDatePickerDialog dpd = HijriDatePickerDialog.newInstance(
                    MainActivity.this,Now.get(Calendar.YEAR),Now.get(Calendar.MONTH),Now.get(Calendar.DAY_OF_MONTH)
            );
            dpd.setMinDate(new UmmalquraCalendar(1440,1));
            dpd.show(getSupportFragmentManager(),"Datepickerdialog");
        });

    }

    @Override
    public void onResume() {
        super.onResume();
        assert getFragmentManager() != null;
        HijriDatePickerDialog dpd = (HijriDatePickerDialog) getSupportFragmentManager().findFragmentByTag("Datepickerdialog");
        if (dpd != null) dpd.setonDateSetListener(this);
    }

    @Override
    public void onDateSet(HijriDatePickerDialog view,int year,int monthOfYear,int dayOfMonth) {
        String date = "You picked the following date: " + dayOfMonth + "/" + (++monthOfYear) + "/" + year;
        System.out.println(date);
        etDate.setText(date);
    }
}

解决方法

这个问题似乎是 msarhan-library 中的一个已知错误。其相关网站上还有一个同时关闭的issue。它表示已在最新版本中应用了修复。

所以我建议您将您的 marhan 库更新到 v2.0.2 版本，这可能会解决您的问题。

更新：

查看您使用的日期选择器库时，我们可以看到它仍然使用 version v2.0.1。要么等到 date-picker-library 的作者修复依赖项，要么构建自己的 date-picker-library 版本。
