android 選定開始日期結束日期彈出框。

首先制定彈出框xml文件

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:gravity="center_horizontal"
    android:orientation="vertical"
    android:paddingTop="10dp" >

    <LinearLayout
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:gravity="center_horizontal"
        android:orientation="vertical"
        android:padding="5dip" >

        <TextView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="開始日期" />

        <DatePicker
            android:id="@+id/datePickerStart"
            android:layout_width="wrap_content"
            android:layout_height="200dp"
            android:calendarViewShown="false" />
    </LinearLayout>


    <LinearLayout
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:gravity="center_horizontal"
        android:orientation="vertical"
        android:padding="5dip" >

        <TextView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="結束日期" />

        <DatePicker
            android:id="@+id/datePickerEnd"
            android:layout_width="wrap_content"
            android:layout_height="200dp"
            android:calendarViewShown="false" />
    </LinearLayout>

</LinearLayout>

然後是公共類，進行選擇設定

具體使用方法：

l_search_time爲點擊彈出對話框的LinearLayout。

兩個TextView在對話框選擇時間完畢後用於顯示起始時間與結束時間。

/**
         * 時間選擇器
         * */
        LinearLayout l_search_time = (LinearLayout)findViewById(R.id.l_search_time);
        l_search_time.setOnClickListener(new View.OnClickListener() {
            Calendar c = Calendar.getInstance();
            TextView from_time = (TextView)findViewById(R.id.from_time);
            TextView end_time = (TextView)findViewById(R.id.end_time);
            @Override
            public void onClick(View v) {
                // 最後一個false表示不顯示日期，如果要顯示日期，最後參數可以是true或者不用輸入
                new DoubleDatePickerDialog(SearchActivity.this, 0, new DoubleDatePickerDialog.OnDateSetListener() {

                    @Override
                    public void onDateSet(DatePicker startDatePicker, int startYear, int startMonthOfYear,
                                          int startDayOfMonth, DatePicker endDatePicker, int endYear, int endMonthOfYear,
                                          int endDayOfMonth) {
                        s_from_time  = String.format("%d-%d-%d", startYear, startMonthOfYear + 1, startDayOfMonth);
