【中文标题】我们可以在单个应用程序中使用 onCreateDialog 中的不同整数同时打印时间选择器和日期吗？

【英文标题】：Can we print Time Picker and Date together in single app using differrent integer in onCreateDialog?

【问题描述】：

包 com.example.timepickerdialog;

导入androidx.appcompat.app.AppCompatActivity；

导入android.app.DatePickerDialog；

导入android.app.Dialog；

导入android.app.TimePickerDialog；

导入android.os.Bundle；

导入android.view.View；

导入android.widget.Button；

导入 android.widget.DatePicker;

导入android.widget.TimePicker；

导入android.widget.Toast；

public class MainActivity extends AppCompatActivity 
    Button button, button2;
    static final int DIALOG_ID = 0, SECONDDIALOGID = 0;
    int ApnaHour;
    int ApnaMinute, ApnaYear, ApanaDay, ApnaMonth;
@Override
protected void onCreate(Bundle savedInstanceState) 
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    DialogListener();


public void DialogListener() 
    button = (Button) findViewById(R.id.button);
    button2 = (Button) findViewById(R.id.button2);
    button.setOnClickListener(new View.OnClickListener() 
        @Override
        public void onClick(View v) 
            showDialog(DIALOG_ID);
        
    );


    button2.setOnClickListener(new View.OnClickListener() 
        @Override
        public void onClick(View v) 
            showDialog(SECONDDIALOGID);
        
    );

此覆盖显示错误中的以下问题。如果我删除 int hh，则 DateDialogPicker 中会显示错误。 请告诉我这段代码是否错误。

@Override
protected Dialog onCreateDialog(int id , int hh) 
    if (id == DIALOG_ID)
        return new TimePickerDialog(MainActivity.this, SaadaTimePickerListener, ApnaHour, ApnaMinute, false);
    return null;
    if (hh== SECONDDIALOGID)
        return new DatePickerDialog(this, DateSaadaPickerListener,ApanaDay, ApnaMonth, ApnaYear);
    return null;

请解决上述覆盖错误。

protected TimePickerDialog.OnTimeSetListener SaadaTimePickerListener = new TimePickerDialog.OnTimeSetListener() 
    @Override
    public void onTimeSet(TimePicker view, int hourOfDay, int minute) 
        ApnaHour = hourOfDay;
        ApnaMinute = minute;
        Toast.makeText(MainActivity.this, ApnaHour + ":" + ApnaMinute, Toast.LENGTH_SHORT).show();

    
;

private DatePickerDialog.OnDateSetListener DateSaadaPickerListener = new DatePickerDialog.OnDateSetListener() 
    @Override
    public void onDateSet(DatePicker view, int year, int month, int dayOfMonth) 
        ApnaMonth = month;
        ApnaYear = year;
        ApanaDay = dayOfMonth;
        Toast.makeText(MainActivity.this, ApanaDay + "/" + ApnaMonth + "/" + ApnaYear, Toast.LENGTH_SHORT).show();
    
;

【参考方案1】：

showDialog 现在已弃用。我已经用当前时间和日期编写了 DatePicker 和 TimePicker 的代码。随意修改。

public void showDatePickerDialog(View v) 
    // Get Current Date or use your own Date
    final Calendar c = Calendar.getInstance();
    int mYear = c.get(Calendar.YEAR);
    int mMonth = c.get(Calendar.MONTH);
    int mDay = c.get(Calendar.DAY_OF_MONTH);

    DatePickerDialog datePickerDialog = new DatePickerDialog(this,
            new DatePickerDialog.OnDateSetListener() 
                @Override
                public void onDateSet(DatePicker view, int year,
                                      int monthOfYear, int dayOfMonth) 
                    //get date here
                
            , mYear, mMonth, mDay);
    datePickerDialog.show();


public void showTimePickerDialog(View v) 
    // Get Current Time or use your own Time
    final Calendar c = Calendar.getInstance();
    int mHour = c.get(Calendar.HOUR_OF_DAY);
    int mMinute = c.get(Calendar.MINUTE);

    // Launch Time Picker Dialog
    TimePickerDialog timePickerDialog = new TimePickerDialog(this,
            new TimePickerDialog.OnTimeSetListener() 
                @Override
                public void onTimeSet(TimePicker view, int hourOfDay,
                                      int minute) 
                    //get time here
                
            , mHour, mMinute, false);
    timePickerDialog.show();
