Android简易的日期选择弹窗

简易的日期弹窗，可将其封装到帮助类中
1、无清除按钮，只能选择日期

  //可使用日期格式化
  protected Dialog showDialogl(TextView rq) {
        String txrq = rq.getText().toString();
        String[] rqd;
        Calendar ca = Calendar.getInstance();
        int mYear = ca.get(Calendar.YEAR);
        int mMonth = ca.get(Calendar.MONTH);
        int mDay = ca.get(Calendar.DAY_OF_MONTH);
        if (!ScanToolsUtils.isNullOrEmpty(txrq)) {
            rqd = txrq.split("-");
            mYear = Integer.parseInt(rqd[0]);
            mMonth = Integer.parseInt(rqd[1]) - 1;
            mDay = Integer.parseInt(rqd[2]);
        }
        DatePickerDialog datePickerDialog = new DatePickerDialog(getActivity(),
                new DatePickerDialog.OnDateSetListener() {
                    @Override
                    public void onDateSet(DatePicker view, int year, int month, int dayOfMonth) {
                        String data = year + "-" + (month + 1) + "-" + dayOfMonth;
                        rq.setText(data);
                    }
                },
                mYear, mMonth, mDay);
        datePickerDialog.show();
        return datePickerDialog;
    }

点击日期文本框调用弹窗

 tv.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                Dialog dialog = showDialogl(tv);
                dialog.show();
            }
        });

2、可进行日期清除，使用AlertDialog来包装DatePicker，并添加一个清除按钮。

private void showDialogl(TextView rq) {
        String txrq = rq.getText().toString();
        String[] rqd;
        Calendar ca = Calendar.getInstance();
        int mYear = ca.get(Calendar.YEAR);
        int mMonth = ca.get(Calendar.MONTH);
        int mDay = ca.get(Calendar.DAY_OF_MONTH);
        if (!ScanToolsUtils.isNullOrEmpty(txrq)) {
            rqd = txrq.split("-");
            mYear = Integer.parseInt(rqd[0]);
            mMonth = Integer.parseInt(rqd[1]) - 1;
            mDay = Integer.parseInt(rqd[2]);
        }
        DatePickerDialog datePickerDialog = new DatePickerDialog(getActivity(),
                new DatePickerDialog.OnDateSetListener() {
                    @Override
                    public void onDateSet(DatePicker view, int year, int month, int dayOfMonth) {
                        String data = year + "-" + (month + 1) + "-" + dayOfMonth;
                        rq.setText(data);
                    }
                },
                mYear, mMonth, mDay);

        AlertDialog.Builder builder = new AlertDialog.Builder(getContext());
        builder.setTitle("选择日期")
                .setView(datePickerDialog.getDatePicker())
                .setPositiveButton("确定", new DialogInterface.OnClickListener() {
                    @Override
                    public void onClick(DialogInterface dialog, int which) {
                        datePickerDialog.onClick(dialog, DialogInterface.BUTTON_POSITIVE);
                    }
                })
                .setNegativeButton("清除", new DialogInterface.OnClickListener() {
                    @Override
                    public void onClick(DialogInterface dialog, int which) {
                        rq.setText("");
                    }
                });
        builder.show();
    }

 tv.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                showDialogl(tv);
            }
        });
