日期 時間選擇器(DatePicker和TimePicker)實現用戶選擇

日期和時間

做者的設計TimePicker時，大小分佈不合理，我調整寬度爲match-parent高度爲wrap-parent就能夠了。

public class MainActivity extends Activity { // 定義5個記錄當前時間的變量 private int year; private int month; private int day; private int hour; private int minute; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); DatePicker datePicker = (DatePicker)findViewById(R.id.datePicker); TimePicker timePicker = (TimePicker)findViewById(R.id.timePicker); // 獲取當前的年、月、日、小時、分鐘 Calendar c = Calendar.getInstance(); year = c.get(Calendar.YEAR); month = c.get(Calendar.MONTH); day = c.get(Calendar.DAY_OF_MONTH); hour = c.get(Calendar.HOUR); minute = c.get(Calendar.MINUTE); // 初始化DatePicker組件，初始化時指定監聽器 datePicker.init(year, month, day, new OnDateChangedListener() { @Override public void onDateChanged(DatePicker arg0, int year , int month, int day) { MainActivity.this.year = year; MainActivity.this.month = month; MainActivity.this.day = day; // 顯示當前日期、時間 showDate(year, month, day, hour, minute); } }); timePicker.setEnabled(true); // 爲TimePicker指定監聽器 timePicker.setOnTimeChangedListener(new OnTimeChangedListener() { @Override public void onTimeChanged(TimePicker view , int hourOfDay, int minute) { MainActivity.this.hour = hourOfDay; MainActivity.this.minute = minute; // 顯示當前日期、時間 showDate(year, month, day, hour, minute); } }); } // 定義在EditText中顯示當前日期、時間的方法 private void showDate(int year, int month , int day, int hour, int minute) { EditText show = (EditText) findViewById(R.id.show); show.setText("您的購買日期爲：" + year + "年" + (month + 1) + "月" + day + "日 " + hour + "時" + minute + "分"); } }

 

XML文件

<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="match_parent" android:layout_height="match_parent"> <TextView android:layout_width="match_parent" android:layout_height="wrap_content" android:text="選擇購買本書的具體時間"/> <!-- 定義一個DatePicker組件 --> <DatePicker android:id="@+id/datePicker" android:layout_width="wrap_content" android:layout_height="200dp" android:layout_gravity="center_horizontal" android:startYear="2000" android:endYear="2016" android:calendarViewShown="true" android:spinnersShown="true"/> <!-- 定義一個TimePicker組件 --> <TimePicker android:id="@+id/timePicker" android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_gravity="center_horizontal"/> <!-- 顯示用戶輸入日期、時間的控件 --> <EditText android:id="@+id/show" android:layout_width="match_parent" android:layout_height="wrap_content" android:editable="false" android:cursorVisible="false"/> </LinearLayout>
