选择一个日期并显示在同一个按钮，日期选择器android

Question

我有一个表格，用户必须输入生日，有一个按钮来选择日期，当用户单击设置，按钮将显示结果的用户，但我只有一个日期，而不是时间，

private SQLiteDatabase database; 
private DBHelper helper; 
Button btnSave, btnDOB; 
EditText addNama, addAddress, addBloodType, addHeight, addDrName, addDrContact, 
     addGuardianName1, addGuardianContact1, addGuardianName2, 
     addGuardianContact2, addHospitalName, addHospitalContact; 

DateFormat fmtDOBDate = DateFormat.getDateTimeInstance(); 
TextView lblDOBDate; 
Calendar myDOBCalendar = Calendar.getInstance(); 

DatePickerDialog.OnDateSetListener d = new DatePickerDialog.OnDateSetListener() { 
public void onDateSet(DatePicker view, int year, int monthOfYear, 
     int dayOfMonth) { 
myDOBCalendar.set(Calendar.YEAR, year); 
myDOBCalendar.set(Calendar.MONTH, monthOfYear); 
myDOBCalendar.set(Calendar.DAY_OF_MONTH, dayOfMonth); 
updateLabelDOBDate(); 
} 
}; 

private void updateLabelDOBDate() { 
    lblDOBDate.setText(fmtDOBDate.format(myDOBCalendar.getTime())); 
} 

@Override 
protected void onCreate(Bundle savedInstanceState) 
{ 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.profile_add); 

    btnSave = (Button)findViewById(R.id.btnSave); 
    btnDOB = (Button)findViewById(R.id.dobbtn); 
    addNama = (EditText)findViewById(R.id.editText1); 
    addAddress = (EditText)findViewById(R.id.editText4); 
    addBloodType = (EditText)findViewById(R.id.editText5); 
    addHeight = (EditText)findViewById(R.id.editText6); 
    addDrName = (EditText)findViewById(R.id.editText7); 
    addDrContact = (EditText)findViewById(R.id.editText8); 
    addGuardianName1 = (EditText)findViewById(R.id.editText9); 
    addGuardianContact1 = (EditText)findViewById(R.id.editText10); 
    addGuardianName2 = (EditText)findViewById(R.id.EditText01); 
    addGuardianContact2 = (EditText)findViewById(R.id.EditText02); 
    addHospitalName = (EditText)findViewById(R.id.editText11); 
    addHospitalContact = (EditText)findViewById(R.id.editText12); 

    helper = new DBHelper(this); 
    database = helper.getWritableDatabase(); 

    btnSave.setOnClickListener(new View.OnClickListener() { 

     @Override 
     public void onClick(View v) { 


      String name = addNama.getText().toString(); 
      String dob = btnDOB.getText().toString(); 
      String address = addAddress.getText().toString(); 
      String bloodtype = addBloodType.getText().toString(); 
      String height = addHeight.getText().toString(); 
      String drname = addDrName.getText().toString(); 
      String drcontact = addDrContact.getText().toString(); 
      String guardianname1 = addGuardianName1.getText().toString(); 
      String guardiancontact1 = addGuardianContact1.getText().toString(); 
      String guardianname2 = addGuardianName2.getText().toString(); 
      String guardiancontact2 = addGuardianContact2.getText().toString(); 
      String hospitalname = addHospitalName.getText().toString(); 
      String hospitalcontact = addHospitalContact.getText().toString(); 

      helper.insertDataProfile(database, name, dob, address, bloodtype, height, 
        drname, drcontact, guardianname1, guardiancontact1, 
        guardianname2, guardiancontact2, hospitalname, 
        hospitalcontact); 
      Toast.makeText(ProfileAdd.this, "Successfully Add", Toast.LENGTH_SHORT).show(); 

      Intent i = new Intent(ProfileAdd.this, ProfileMain.class); 
      startActivity(i); 

     } 
    }); 


    lblDOBDate = (TextView) findViewById(R.id.dobbtn); 
    Button btnStartDate = (Button) findViewById(R.id.dobbtn); 
    btnStartDate.setOnClickListener(new View.OnClickListener() { 
     public void onClick(View v) { 
      new DatePickerDialog(ProfileAdd.this, d, myDOBCalendar 
        .get(Calendar.YEAR), myDOBCalendar.get(Calendar.MONTH), 
        myDOBCalendar.get(Calendar.DAY_OF_MONTH)).show(); 
     } 
    }); 

    updateLabelDOBDate(); 
} 

public void onClickCancel(View v){ 
    startActivity (new Intent(getApplicationContext(), ProfileMain.class)); 
}

您需要执行如下：

private DatePickerDialog.OnDateSetListener datePickerListener = new DatePickerDialog.OnDateSetListener() { 

      // when dialog box is closed, below method will be called. 
      public void onDateSet(DatePicker view, int selectedYear, 
        int selectedMonth, int selectedDay) { 
       int year = selectedYear; 
       int month = selectedMonth; 
       int day = selectedDay; 

       your_button.setText(new StringBuilder().append(year).append("-") 
         .append(month + 1).append("-").append(day).append(" ")); 


      } 
     }; 

像这样创建新的DatePicker对话的对象：

Calendar cal=Calendar.getInstance(); 

     year=cal.get(Calendar.YEAR); 
     month=cal.get(Calendar.MONTH); 
     day=cal.get(Calendar.DATE); 


new DatePickerDialog(this, datePickerListener, year, month,day); //Call this on button click
