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。
当前回答
把这4行放在(EditText, AppCompatEditText)上。它不会显示键盘。然后在clicklistener上，你可以显示datePicker
android:clickable="false"
android:cursorVisible="false"
android:focusable="false"
android:focusableInTouchMode="false"
其他回答
如果你需要一个单一的功能，所有的活动，当调用将打开日期选择器，然后返回我选择的日期，然后为所有创建一个接口
public interface OnDatePickerLitionarCallBack {
void DatePicker(String selectedDate);
}
然后在活动中调用接口
public class MapsActivity extends FragmentActivity implements OnDatePickerLitionarCallBack {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_maps);
findViewById(R.id.date_pick).setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
date_Picker(MapsActivity.this,MapsActivity.this);
}
});
}
@Override
public void DatePicker(String selectedDate) {
}
}
实现接口后，创建一个公共类用于访问任何活动或片段
public class Commons{
public static void date_Picker(Context context, OnDatePickerLitionarCallBack onDatePickerLitionarCallBack) {
final java.util.Calendar myCalendar = java.util.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(java.util.Calendar.YEAR, year);
myCalendar.set(java.util.Calendar.MONTH, monthOfYear);
myCalendar.set(java.util.Calendar.DAY_OF_MONTH, dayOfMonth);
String myFormat = "dd,MMM yyyy"; //In which you need put here
java.text.SimpleDateFormat sdf = new java.text.SimpleDateFormat(myFormat, Locale.US);
onDatePickerLitionarCallBack.DatePicker(sdf.format(myCalendar.getTime()));
}
};
DatePickerDialog datePickerDialog = new DatePickerDialog(context, date, myCalendar
.get(java.util.Calendar.YEAR), myCalendar.get(java.util.Calendar.MONTH),
myCalendar.get(java.util.Calendar.DAY_OF_MONTH));
datePickerDialog.show();
}
}
还有另一种更好的可重用方式:
创建一个类:
class setDate implements OnFocusChangeListener, OnDateSetListener {
private EditText editText;
private Calendar myCalendar;
public setDate(EditText editText, Context ctx){
this.editText = editText;
this.editText.setOnFocusChangeListener(this);
myCalendar = Calendar.getInstance();
}
@Override
public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) {
// this.editText.setText();
String myFormat = "MMM dd, yyyy"; //In which you need put here
SimpleDateFormat sdformat = new SimpleDateFormat(myFormat, Locale.US);
myCalendar.set(Calendar.YEAR, year);
myCalendar.set(Calendar.MONTH, monthOfYear);
myCalendar.set(Calendar.DAY_OF_MONTH, dayOfMonth);
editText.setText(sdformat.format(myCalendar.getTime()));
}
@Override
public void onFocusChange(View v, boolean hasFocus) {
// TODO Auto-generated method stub
if(hasFocus){
new DatePickerDialog(ctx, this, myCalendar
.get(Calendar.YEAR), myCalendar.get(Calendar.MONTH),
myCalendar.get(Calendar.DAY_OF_MONTH)).show();
}
}
}
然后在onCreate函数下调用这个类:
EditText editTextFromDate = (EditText) findViewById(R.id.editTextFromDate);
setDate fromDate = new setDate(editTextFromDate, this);
我已经尝试了所有建议的方法，但它们都有各自的问题。
在我看来，最好的解决方案是使用如下的框架布局:
<FrameLayout
android:layout_width="match_parent"
android:layout_height="wrap_content" >
<EditText
android:layout_width="match_parent"
android:layout_height="wrap_content"
.... />
<View
android:id="@+id/invisible_click_watcher"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:clickable="true" />
</FrameLayout>
然后添加DatePickerDialog代码，这个代码在@Android的回答中写得很漂亮。
<EditText
android:id="@+id/date"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:ems="10"
android:hint="DD/MM/YYYY"
android:inputType="date"
android:focusable="false"/>
<EditText
android:id="@+id/time"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:hint="00:00"
android:inputType="time"
android:focusable="false"/>
