android - 在 Android 版本 7.0 上膨胀类 android.widget.DatePicker 时出错

Question

我想显示弹出式日期选择器并且我使用了这段代码

Calendar mcurrentDate = Calendar.getInstance();
            int mYear = mcurrentDate.get(Calendar.YEAR);
            int mMonth = mcurrentDate.get(Calendar.MONTH);
            int mDay = mcurrentDate.get(Calendar.DAY_OF_MONTH);

            DatePickerDialog mDatePicker = new DatePickerDialog(getActivity(), new DatePickerDialog.OnDateSetListener() {
                public void onDateSet(DatePicker datepicker, int selectedyear, int selectedmonth, int selectedday) {
                    txtDate1.setText(selectedmonth + "/" + selectedday + "/" + selectedyear);
                }
            }, mYear, mMonth, mDay);
            mDatePicker.setTitle("Select date");
            mDatePicker.show();

我的xml文件

<LinearLayout android:layout_width="match_parent" android:layout_height="wrap_content"
android:orientation="horizontal" android:id="@+id/lLdate1">
<TextView android:text="Tgl 1" android:textSize="15sp" android:textStyle="bold"
android:textColor="@color/black" android:layout_width="95dp" android:layout_height="wrap_content"/>
<EditText android:id="@+id/txtDate1" android:layout_width="130dp" android:layout_height="wrap_content"
android:textColor="@color/black" android:textSize="15dp" android:singleLine="true"
android:editable="false"> </EditText>
<ImageButton android:id="@+id/imgCal1" android:layout_width="wrap_content"
android:layout_height="wrap_content" android:padding="7dp"
android:cropToPadding="true" android:src="@drawable/calendar25"/> </LinearLayout>

在 7.0 以下的 Android 版本上它工作正常。但是在 android 7.0 上我得到了错误

android.view.InflateException: Binary XML file line #18: Binary XML file line #18: Error inflating class android.widget.DatePicker

请帮帮我

Answer 1

试试这个。

声明这些变量

private DateDialog dialog;
boolean click=false;

在onCreate方法中点击imgCal1时处理

imgCal1.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View arg0) {
                click=true;
                Dialog dialogFrg=dialog.getDialog();
               if(dialogFrg!=null && dialogFrg.isShowing()) {
            // no need to call dialog.show(ft, "DatePicker");
        } else {
            FragmentTransaction ft = getSupportFragmentManager().beginTransaction();
            dialog.show(ft, "DatePicker");
        }
            }
        });

之后只添加这个

public static class DateDialog extends android.support.v4.app.DialogFragment implements DatePickerDialog.OnDateSetListener {

        public DateDialog() {
        }

        public Dialog onCreateDialog(Bundle savedInstanceState) //display calender
        {
            final Calendar c=Calendar.getInstance();
            int year=c.get(Calendar.YEAR);
            month=c.get(Calendar.MONTH);
            int day=c.get(Calendar.DAY_OF_MONTH);
            return new DatePickerDialog(getActivity(),this,year, month,day);
        }

        public void onDateSet(DatePicker view,int year, int month, int day)
        {
            String date1=year+"-"+String.format("%02d", month+1)+"-"+String.format("%02d", day);
            date.setText(date1);
            date2= date.getText().toString();
            return ;
            //t.add_new(date);
        }
    }
