添加时间选择器到日期选择器android

Question

我试图添加time picker到日期选择器。我是java的初学者，也许有人可以给我正确的方式？我希望时间选择器出现在日历视图顶部，之后我选择日期，时间选择器弹出。可能吗 ？在xml文件中，只有少数EditText字段在此类中已经声明。

public class CompletedWorksActivity extends Activity implements 
     DatePickerDialog.OnDateSetListener, OnClickListener, OnTimeSetListener { 
    private TextView text_date; 
    private Button search; 
    private EditText from; 
    private EditText to; 
    private int yearfrom; 
    private int monthfrom; 
    private int dayfrom; 
    private int hourfrom; 
    private int minfrom; 
    private int yearto; 
    private int monthto; 
    private int dayto; 
    private int hourto; 
    private int minto; 
    private int hour; 
    private int min; 
    private DatePickerDialog date_picker; 
    private TimePickerDialog time_picker; 
    private boolean fromEdit; 
    private boolean toEdit; 

    @Override 
    protected void onCreate(Bundle menuinstance) { 
     super.onCreate(menuinstance); 
     setContentView(R.layout.completed_works); 

     Intent intent = getIntent(); // gaunam 
     User user = (User) intent.getSerializableExtra("user"); 

     from = (EditText) findViewById(R.id.datefrom); 
     to = (EditText) findViewById(R.id.dateto); 
     Calendar cal = Calendar.getInstance(); 
     hour = cal.get(Calendar.HOUR_OF_DAY); 
     min = cal.get(Calendar.MINUTE); 
     date_picker = new DatePickerDialog(this, this, cal.get(Calendar.YEAR), 
       cal.get(Calendar.MONTH), cal.get(Calendar.DAY_OF_MONTH)); 
     date_picker.getDatePicker().setCalendarViewShown(true); 
     date_picker.getDatePicker().setSpinnersShown(false); 
     time_picker = new TimePickerDialog(this, this, hour, min, true); 
     from.setOnFocusChangeListener(focusListener); 
     to.setOnFocusChangeListener(focusListener); 
     time_picker.set 

     search = (Button) findViewById(R.id.searchSubmit); 

     // search.setOnClickListener(searchlistener); 
    } 

    @Override 
    public void onDateSet(DatePicker dp, int y, int m, int d) { 
     String cheapDate = y + "-" + (m + 1) + "-" + d; 
     View v = getCurrentFocus(); 
     if (v == from) { 
      yearfrom = y; 
      monthfrom = m; 
      dayfrom = d; 
      Log.d("year from ", "" + yearfrom + monthfrom + dayfrom); 
     } else { 
      yearto = y; 
      monthto = m; 
      dayto = d; 
      Log.d("year to ", "" + yearto + monthto + dayto); 
      // Toast.makeText(getApplicationContext(),yearto+monthto+dayto , 
      // Toast.LENGTH_LONG).show(); 
     } 
     if (fromEdit) { 
      from.setText(cheapDate); 
     } else { 
      to.setText(cheapDate); 
     } 

    } 

    private View.OnClickListener searchlistener = new View.OnClickListener() { 

     @Override 
     public void onClick(View v) { 
      // TODO Auto-generated method stub 

     } 
    }; 

    private View.OnFocusChangeListener focusListener = new View.OnFocusChangeListener() { 
     @Override 
     public void onFocusChange(View v, boolean hasFocus) { 
      if (hasFocus) { 
       EditText edit = (EditText) v; 
       int len = edit.getText().toString().length(); 

       if (edit == findViewById(R.id.datefrom)) { 
        Toast.makeText(getApplicationContext(), "Data nuo ? ", 
          Toast.LENGTH_LONG).show(); 
        fromEdit = v.getId() == R.id.datefrom; 
        date_picker.show(); 
       } else { 
        Toast.makeText(getApplicationContext(), "Data iki ? ", 
          Toast.LENGTH_LONG).show(); 
        fromEdit = v.getId() == R.id.datefrom; 
        date_picker.show(); 

       } 
      } 
     } 

    }; 

    @Override 
    public void onTimeSet(TimePicker view, int hourOfDay, int minute) { 
     // TODO Auto-generated method stub 

    } 

    @Override 
    public void onClick(View v) { 
     // TODO Auto-generated method stub 

    } 



}

Android使用android.widget.TimePicker component设置时间非常简单。

请参阅this Tutorial在这里您可以看到用户如何使用易于使用的对话框android.app.TimePickerDialog来选择小时和分钟。

尝试像下面的代码：

date_time_layout.xml

<DatePicker 
    android:id="@+id/datePicker1" 
    android:layout_width="wrap_content" 
    android:layout_height="0dp" 
    android:layout_weight="1" 
    android:calendarViewShown="false" > <!-- style="@style/date_picker_style" --> 
</DatePicker> 

<TimePicker 
    android:id="@+id/timePicker1" 
    android:layout_width="wrap_content" 
    android:layout_height="0dp" 
    android:layout_weight="1" > 
</TimePicker> 

<LinearLayout 
    android:layout_width="fill_parent" 
    android:layout_height="wrap_content" 
    android:layout_marginBottom="10dp" 
    android:layout_marginLeft="5dp" 
    android:layout_marginRight="5dp" > 

    <Button 
     android:id="@+id/btnCancelDT" 
     android:layout_width="0dip" 
     android:layout_height="wrap_content" 
     android:layout_weight="1" 
     android:background="@drawable/button_selector" 
     android:text="Cancel" 
     android:textColor="@color/white" 
     android:textStyle="bold" /> 

    <Button 
     android:id="@+id/btnSetDT" 
     android:layout_width="0dip" 
     android:layout_height="wrap_content" 
     android:layout_weight="1" 
     android:background="@drawable/button_selector" 
     android:text="Set" 
     android:textColor="@color/white" 
     android:textStyle="bold" /> 
</LinearLayout> 

Activity类：

public void showDateTimePickerDialog() { 


     final Dialog dialog = new Dialog(this); 

     dialog.setContentView(R.layout.date_time_layout); 

     dialog.setTitle("Set Schedule Call"); 

     dialog.show(); 

     Button btnCancel = (Button)dialog.findViewById(R.id.btnCancelDT); 
     Button btnSet = (Button)dialog.findViewById(R.id.btnSetDT); 

     final DatePicker dp = (DatePicker)dialog.findViewById(R.id.datePicker1); 
     final TimePicker tp = (TimePicker)dialog.findViewById(R.id.timePicker1); 


     btnCancel.setOnClickListener(new OnClickListener() { 

      @Override 
      public void onClick(View arg0) { 
       // TODO Auto-generated method stub 
       dialog.dismiss(); 
      } 
     }); 

     btnSet.setOnClickListener(new OnClickListener() { 

      @Override 
      public void onClick(View arg0) { 
       String am_pm = ""; 
       // TODO Auto-generated method stub 
       int m = dp.getMonth()+1; 
       int d = dp.getDayOfMonth(); 
       int y = dp.getYear(); 

       int h = tp.getCurrentHour(); 
       int min = tp.getCurrentMinute(); 

       String strm = String.valueOf(min); 

       if(strm.length()==1){ 
        strm = "0"+strm; 
       } 
       if(h>12){ 
        am_pm = "PM"; 
        h = h-12; 
       }else{ 
        am_pm = "AM"; 
       } 

       date = m+"/"+d+"/"+y+" "+h+":"+strm+":00 "+am_pm; 
       time = h+":"+strm+" "+am_pm; 

          System.out.println("Date: " + date +" Time: "+ time); 

       dialog.dismiss(); 
      } 
     }); 
    } 

在按钮单击或按需要时调用此方法。
