我想显示日期选择器弹出窗口。我找到了一些例子,但我没有得到正确的。我有一个edittext,我希望当我点击edittext时,datepicker对话框应该弹出,设置日期后,日期应该显示在edittext在dd/mm/yyyy格式。请为我提供示例代码或良好的链接。

使用数据绑定:
<EditText
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:focusable="false"
android:onClick="@{() -> viewModel.onDateEditTextClicked()}"
android:hint="@string/hint_date"
android:imeOptions="actionDone"
android:inputType="none"
android:maxLines="1"
android:text="@={viewModel.filterDate}" />
(参见focusable, inputType和onClick)
在视图模型:
public void onDateEditTextClicked() {
// do something
}

选中的答案不太适合我,因为我必须点击EditText框一次,然后在OnClickListener启动之前再次点击它。我能够通过用OnTouchListener替换OnClickListener来修复这个问题,以防有人遇到类似的问题,下面是我的代码看起来是什么样的:
Calendar myCalendar = Calendar.getInstance();
DatePickerDialog.OnDateSetListener date = new
DatePickerDialog.OnDateSetListener() {
@Override
public void onDateSet(DatePicker view, int year, int monthOfYear,
int dayOfMonth) {
// TODO Auto-generated method stub
myCalendar.set(Calendar.YEAR, year);
myCalendar.set(Calendar.MONTH, monthOfYear);
myCalendar.set(Calendar.DAY_OF_MONTH, dayOfMonth);
updateLabel();
}
};
edittext.setOnTouchListener(new View.OnTouchListener() {
@Override
public void onTouch(View v, MotionEvent event) {
if(event.getAction() == MotionEvent.ACTION_DOWN) {
new DatePickerDialog(classname.this, date, myCalendar
.get(Calendar.YEAR), myCalendar.get(Calendar.MONTH),
myCalendar.get(Calendar.DAY_OF_MONTH)).show();
}
}
});
private void updateLabel() {
String myFormat = "MM/dd/yy"; //In which you need put here
SimpleDateFormat sdf = new SimpleDateFormat(myFormat, Locale.US);
edittext.setText(sdf.format(myCalendar.getTime()));
}
我的类为show DatePicker。我可以使用EditText, TextView或按钮
import android.app.DatePickerDialog;
import android.content.Context;
import android.view.View;
import android.widget.DatePicker;
import android.widget.TextView;
import java.text.SimpleDateFormat;
import java.util.Calendar;
import java.util.Date;
import java.util.TimeZone;
public class TextViewDatePicker
implements View.OnClickListener, DatePickerDialog.OnDateSetListener {
public static final String DATE_SERVER_PATTERN = "yyyy-MM-dd";
private DatePickerDialog mDatePickerDialog;
private TextView mView;
private Context mContext;
private long mMinDate;
private long mMaxDate;
public TextViewDatePicker(Context context, TextView view) {
this(context, view, 0, 0);
}
public TextViewDatePicker(Context context, TextView view, long minDate, long maxDate) {
mView = view;
mView.setOnClickListener(this);
mView.setFocusable(false);
mContext = context;
mMinDate = minDate;
mMaxDate = maxDate;
}
@Override
public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) {
Calendar calendar = Calendar.getInstance();
calendar.set(Calendar.YEAR, year);
calendar.set(Calendar.MONTH, monthOfYear);
calendar.set(Calendar.DAY_OF_MONTH, dayOfMonth);
Date date = calendar.getTime();
SimpleDateFormat formatter = new SimpleDateFormat(DATE_SERVER_PATTERN);
mView.setText(formatter.format(date));
}
@Override
public void onClick(View v) {
Calendar calendar = Calendar.getInstance(TimeZone.getDefault());
mDatePickerDialog = new DatePickerDialog(mContext, this, calendar.get(Calendar.YEAR),
calendar.get(Calendar.MONTH), calendar.get(Calendar.DAY_OF_MONTH));
if (mMinDate != 0) {
mDatePickerDialog.getDatePicker().setMinDate(mMinDate);
}
if (mMaxDate != 0) {
mDatePickerDialog.getDatePicker().setMaxDate(mMaxDate);
}
mDatePickerDialog.show();
}
public DatePickerDialog getDatePickerDialog() {
return mDatePickerDialog;
}
public void setMinDate(long minDate) {
mMinDate = minDate;
}
public void setMaxDate(long maxDate) {
mMaxDate = maxDate;
}
}
使用
EditText myEditText = findViewById(R.id.myEditText);
TextViewDatePicker editTextDatePicker = new TextViewDatePicker(context, myEditText, minDate, maxDate);
//TextViewDatePicker editTextDatePicker = new TextViewDatePicker(context, myEditText); //without min date, max date
日期选择对话框
Calendar c=Calendar.getInstance();
Integer month=c.get(Calendar.MONTH);
Integer day=c.get(Calendar.DAY_OF_MONTH);
Integer year=c.get(Calendar.YEAR);
DatePickerDialog datePickerDialog =new DatePickerDialog(Expenture_Activity.this, new DatePickerDialog.OnDateSetListener() {
@Override
public void onDateSet(DatePicker view, int year, int month, int dayOfMonth) {
et_from.setText(dayOfMonth+"/"+month+"/"+year);
}
},year,month,day);
datePickerDialog.show();
在XML文件中试试这个:
<EditText
android:id="@+id/Birthday"
custom:font="@string/font_avenir_book"
android:clickable="false"
android:cursorVisible="false"
android:focusable="false"
android:focusableInTouchMode="false"
android:hint="@string/birthday"/>
在Java文件中是这样的:
public class MainActivity extends AppCompatActivity {
final Calendar myCalendar= Calendar.getInstance();
EditText editText;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
editText=(EditText) findViewById(R.id.BirthDate);
DatePickerDialog.OnDateSetListener date =new DatePickerDialog.OnDateSetListener() {
@Override
public void onDateSet(DatePicker view, int year, int month, int day) {
myCalendar.set(Calendar.YEAR, year);
myCalendar.set(Calendar.MONTH,month);
myCalendar.set(Calendar.DAY_OF_MONTH,day);
updateLabel();
}
};
editText.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
new DatePickerDialog(MainActivity.this,date,myCalendar.get(Calendar.YEAR),myCalendar.get(Calendar.MONTH),myCalendar.get(Calendar.DAY_OF_MONTH)).show();
}
});
}
private void updateLabel(){
String myFormat="MM/dd/yy";
SimpleDateFormat dateFormat=new SimpleDateFormat(myFormat, Locale.US);
editText.setText(dateFormat.format(myCalendar.getTime()));
}
}
在EditText的xml文件中添加android:focusable="false"以允许单个触摸。
selectDate.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
DatePickerDialog mdiDialog =new DatePickerDialog(mContext,new DatePickerDialog.OnDateSetListener() {
@Override
public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) {
Toast.makeText(getApplicationContext(),year+ " "+monthOfYear+" "+dayOfMonth,Toast.LENGTH_LONG).show();
}
}, year, month, date);
mdiDialog.show();
}
});
