使用彈出日曆在另一個活動中顯示選定的日期

Question

我想在另一個活動中顯示日曆中的選定日期，所以請幫助我，現在在我的應用程序中顯示當前日期，但我不知道如何執行此操作。我在我的應用程序中使用簡單的彈出式日曆。下面是我的代碼。

sharedpreferences = getSharedPreferences(MyPREFERENCES, MODE_PRIVATE); 

    Bundle b = getIntent().getExtras(); 

    txt_date = (TextView) findViewById(R.id.Date_Value); 
    txt_week = (TextView) findViewById(R.id.Week_Value); 
    txt_baby = (TextView) findViewById(R.id.Baby_Value); 
    txt_mother = (TextView) findViewById(R.id.Mother_Value); 
    txt_tremester = (TextView) findViewById(R.id.Tremester_Value); 

    txt_baby.setText(b.getCharSequence("baby_name")); 
    txt_mother.setText(b.getCharSequence("mother_name")); 
    txt_tremester.setText(b.getCharSequence("tremester")); 

    img_week = (ImageView) findViewById(R.id.image_week); 
    img_slide = (ImageView) findViewById(R.id.image_slide); 
    img_BMI = (ImageView) findViewById(R.id.image_BMI); 
    img_setting = (ImageView) findViewById(R.id.image_setting); 

    String dob = sharedpreferences.getString("dob", null); 

    Calendar c = Calendar.getInstance(); 
    year = c.get(Calendar.YEAR); 
    month = c.get(Calendar.MONTH); 
    day = c.get(Calendar.DAY_OF_MONTH); 



    txt_date.setText(new StringBuilder() 
      // Month is 0 based, just add 1 
      .append(year).append("-").append(month + 1).append("-").append(day)); 

    String current_dob = txt_date.getText().toString(); 

    StringTokenizer current_tokens = new StringTokenizer(current_dob, "-"); 
    current_year = current_tokens.nextToken(); 
    current_month = current_tokens.nextToken(); 
    current_date = current_tokens.nextToken(); 

    System.out.println("year==>" + Integer.parseInt(current_year)); 
    System.out.println("month==>" + Integer.parseInt(current_month)); 
    System.out.println("date==>" + Integer.parseInt(current_date)); 

    StringTokenizer tokens = new StringTokenizer(dob, "-"); 
    selected_year = tokens.nextToken(); 
    selected_month = tokens.nextToken(); 
    selected_date = tokens.nextToken(); 

    System.out.println("year==>" + Integer.parseInt(selected_year)); 
    System.out.println("month==>" + Integer.parseInt(selected_month)); 
    System.out.println("date==>" + Integer.parseInt(selected_date));

使用日曆視圖和設置您選擇的日期如下：

Calendar calendar = Calendar.getInstance(); 
calendar.set(Calendar.YEAR, year); 
calendar.set(Calendar.MONTH, month); 
calendar.set(Calendar.DAY_OF_MONTH, day); 

long milliTime = calendar.getTimeInMillis(); 

mCalendarView.setDate (milliTime, true, true);
