内容图文

我使用以下代码从EditText创建一个DatePickerDialog.

import android.widget.DatePicker;
import android.app.DatePickerDialog;
import java.text.SimpleDateFormat;
import java.util.Calendar;
import java.util.Locale;

Calendar myCalendar = Calendar.getInstance();

String myFormat = "MM/dd/yy";
SimpleDateFormat sdf = new SimpleDateFormat(myFormat, Locale.US);

@Override
    protected void onCreate(Bundle savedInstanceState) {

EditText datePicker = (EditText) findViewById(R.id.popUpDate);
datePicker.setText(sdf.format(myCalendar.getTime()));

datePicker.setOnClickListener(new View.OnClickListener() {

    @Override
    public void onClick(View v) {
        new DatePickerDialog(AddAccount.this, R.style.AppTheme_Dialog, new DatePickerDialog.OnDateSetListener() {
            @Override
            public void onDateSet(DatePicker view, int year, int monthOfYear,
                                  int dayOfMonth) {
                myCalendar.set(Calendar.YEAR, year);
                myCalendar.set(Calendar.MONTH, monthOfYear);
                myCalendar.set(Calendar.DAY_OF_MONTH, dayOfMonth);
                datePicker.setText(sdf.format(myCalendar.getTime()));
            }
        }, myCalendar.get(Calendar.YEAR), myCalendar.get(Calendar.MONTH),
                myCalendar.get(Calendar.DAY_OF_MONTH)).show();
    }
});
}

在选择日期后,是否可以自动关闭默认值？或者这需要完全重制datepicker小部件？

解决方法:

创建一个MyPicker类:)

    import static yourPackageName.MainActivity.sdf; // get static imports


    public class MyPicker extends DatePickerDialog {

    Context context;
    @Override
    public DatePicker getDatePicker() {
        return super.getDatePicker();
    }


    public MyPicker(Context context, int themeResId, OnDateSetListener listener, int year, int monthOfYear, int dayOfMonth) {
        super(context, themeResId, listener, year, monthOfYear, dayOfMonth);
        this.context = context;
    }

    @Override
    public void onDateChanged(DatePicker view, int year, int month, int dayOfMonth) {
        myCalendar.set(Calendar.YEAR, year);
        myCalendar.set(Calendar.MONTH, month);
        myCalendar.set(Calendar.DAY_OF_MONTH, dayOfMonth);
        datePicker.setText(sdf.format(myCalendar.getTime()));
        datePickerDialog.dismiss();
    }
}

现在假设您的主要类在MainActivity中

public class MainActivity extends AppCompatActivity {


    public static Calendar myCalendar = Calendar.getInstance();


    public static String myFormat = "MM/dd/yy";
    public static SimpleDateFormat sdf = new SimpleDateFormat(myFormat, Locale.US);
    public static EditText datePicker;
    public static MyPicker datePickerDialog;

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

        datePicker = (EditText) findViewById(R.id.popUpDate);
        datePicker.setText(sdf.format(myCalendar.getTime()));

        datePicker.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                datePickerDialog = new MyPicker(MainActivity.this, R.style.AppTheme_Dialog, new DatePickerDialog.OnDateSetListener() {
                    @Override
                    public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) {
                    }
                }, myCalendar.get(Calendar.YEAR), myCalendar.get(Calendar.MONTH), myCalendar.get(Calendar.DAY_OF_MONTH));
                datePickerDialog.show();
            }

        });
    }

}
}

或者如果您不需要应用样式

public class MainActivity extends AppCompatActivity {

    public  String myFormat = "MM/dd/yy";
    public  SimpleDateFormat sdf = new SimpleDateFormat(myFormat, Locale.US);
    public  EditText datePicker;
    final Calendar calendar = Calendar.getInstance();
    private DatePickerDialog datePickerDialog;

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

        datePicker = (EditText) findViewById(R.id.popUpDate);
        datePicker.setText(sdf.format(calendar.getTime()));

        datePicker.setOnClickListener(new View.OnClickListener() {

            @Override
            public void onClick(View v) {
                datePickerDialog = new DatePickerDialog(MainActivity.this, null, calendar.get(Calendar.YEAR), calendar.get(Calendar.MONTH), calendar.get(Calendar.DAY_OF_MONTH));
                datePickerDialog.getDatePicker().init(calendar.get(Calendar.YEAR), calendar.get(Calendar.MONTH), calendar.get(Calendar.DAY_OF_MONTH), new DatePicker.OnDateChangedListener() {
                    @Override
                    public void onDateChanged(DatePicker view, int year, int monthOfYear, int dayOfMonth) {
                        calendar.set(Calendar.YEAR, year);
                        calendar.set(Calendar.MONTH, monthOfYear);
                        calendar.set(Calendar.DAY_OF_MONTH, dayOfMonth);
                        datePicker.setText(sdf.format(calendar.getTime()));
                        datePickerDialog.dismiss();
                    }
                });
                datePickerDialog.show();
            }
        });
    }
}

奇迹般有效！
