如何在编辑文本中设置日期 [英] how to set date in edit text

问题描述

我有一个编辑文本框，并且我调用了ontouchlistener，它显示了一个自定义对话框，当我单击setdate按钮时，应该在编辑文本上设置日期选择器上的日期，并且该对话框应该关闭.但我不知道如何从日期选择器中获取日期以及如何在编辑文本框中进行设置.我在date.init(year，monthOfYear，dayOfMonth，new MyOnDateChangedListener())中遇到错误;并且错误是在此行的多个标记-dayOfMonth无法解析为多变的-无法将年份解析为变量-无法将monthOfYear解析为变量

i have a edit text box and i have call ontouchlistener it show a custom dialog and when i click setdate button the date on date picker should set on the edit text and the dialog should get dismiss. but i dont know how to get date from date picker and how to set in edit text box. i am getting error in date.init( year, monthOfYear, dayOfMonth, new MyOnDateChangedListener() ); and the error isMultiple markers at this line - dayOfMonth cannot be resolved to a variable - year cannot be resolved to a variable - monthOfYear cannot be resolved to a variable

 et4.setOnTouchListener(new OnTouchListener() {
    final Dialog setdatedialog = new Dialog(DropboxActivity.this);                      
    public void onClick(View v) {
    }
    public boolean onTouch(View arg0, MotionEvent arg1) {
    setdatedialog.setContentView(R.layout.datedialog);
    setdatedialog.setTitle("select date of puchase");
    setdatedialog.setCancelable(true);
    setdatedialog.show();
    Button back = (Button)setdatedialog.findViewById(R.id.back3);
    back.setOnClickListener(new OnClickListener() {
    public void onClick(View v) {
    setdatedialog.dismiss();
    }
    });
    Button setdate=(Button)setdatedialog.findViewById(R.id.setdate);
    DatePicker date = (DatePicker)setdatedialog.findViewById(R.id.datePicker1);                         
    class MyOnDateChangedListener implements OnDateChangedListener {
        public void onDateChanged(DatePicker view, int year, int monthOfYear, int dayOfMonth){
            et4.setText( "" + dayOfMonth + "-" + (monthOfYear + 1) + "-" + year );
    }
    };
    date.init( year, monthOfYear, dayOfMonth, new MyOnDateChangedListener() );

    return false;
    }

推荐答案

在xml以及活动中的以下代码中定义editText和Button:

Define editText and Button in xml and below code in your activity:

        editText=(EditText) findViewById(R.id.date);
        button=(Button) findViewById(R.id.play);
        button.setOnClickListener(new OnClickListener() {
            public void onClick(View v) {
                showDialog(DATE_DIALOG_ID);
            }
        });

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

现在添加这两个函数以调用DatePicker对话框并在Edittext中设置日期

Now add these two functions to call DatePicker Dialog and to set date in the Edittext

protected Dialog onCreateDialog(int id) {
        switch (id) {
        case DATE_DIALOG_ID:
            return new DatePickerDialog(this,
                        mDateSetListener,
                        mYear, mMonth, mDay);

        }

        return null;

    }
    private DatePickerDialog.OnDateSetListener mDateSetListener =new DatePickerDialog.OnDateSetListener() {

        public void onDateSet(DatePicker view, int year, int monthOfYear,
                int dayOfMonth) {
            mYear = year;
            mMonth = monthOfYear;
            mDay = dayOfMonth;
            editText.setText(new StringBuilder().append(mDay).append("/").append(mMonth+1).append("/").append(mYear));

        }

    };

全局定义:

    static final int DATE_DIALOG_ID = 0;
    private int mYear,mMonth,mDay;
