问题描述

所以问题很简单:

我在我的应用程序中集成了一个 DatePicker.不是作为 DialogDatePicker 而是作为视图组件(更准确地说是 Fragment 内的 View,它动态显示并从 FrameLayout 包含在我的主要 FragmentActiviy 布局中.).

I have integrated a DatePicker in my application.Not as a DialogDatePicker but as a View component (more precisely a View inside of a Fragment that is dynamically shown and removed from a FrameLayout contained in my main FragmentActiviy layout.).

现在我的问题是这个 DataPicker 看起来像这样:

now my problem is that this DataPicker looks like this:

而不是这样:

即使我的目标是更高的 API,我也尝试将 Min SDK 设置为 16 或 17,但也没有任何帮助.

even when I target the higher API's, I tried setting my Min SDK to 16 or 17 as well but it didn't do any help either.

有人知道为什么会这样吗?以及如何显示数据选择器的新外观?最好还是在旧版本的 Android 上?

Some one know why it happens? and how can I show the new look of the data picker?preferably on old versions of Android as well?

任何帮助将不胜感激.

谢谢.

代码:

DataPickerFragment xml:

<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:orientation="vertical"
    android:paddingLeft="6.5dp"
    android:paddingTop="6dp"
    android:paddingRight="8.5dp"
    android:paddingBottom="8.5dp"
    android:background="@drawable/date_picker_background">

    <DatePicker
        android:id="@+id/datePicker"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_margin="10dp"
        android:paddingBottom="40dp" />

    <LinearLayout 
        android:layout_width="match_parent"
        android:layout_height="match_parent">

        <Button
            android:id="@+id/bCancel"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_gravity="bottom"
            android:layout_weight="1.0"
            android:onClick="buttonCanceDatePickerOnclick"
            android:text="@string/cancel" />

        <Button
            android:id="@+id/bSave"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_gravity="bottom"
            android:layout_weight="1.0"
            android:onClick="buttonSaveDatePickerOnclick"
            android:text="@string/save" />

     </LinearLayout>
</FrameLayout>

DataPickerFramgnet 类:

public class DatePickerFragment extends Fragment {

    private Button bSave, bCancel;

    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
        View rootView = inflater.inflate(R.layout.date_picker_fragment_layout, 
                                         container, false);
        return rootView;
    }
}

更新:

Manifast 文件:

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.emildesign.sgreportmanager"
android:versionCode="1"
android:versionName="1.0">

    <uses-sdk
        android:minSdkVersion="13"
        android:targetSdkVersion="17" />

    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
    <uses-permission android:name="android.permission.INTERNET" />
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>

    <!--  Crittercism  -->
    <uses-permission android:name="android.permission.READ_LOGS"/>
    <uses-permission android:name="android.permission.GET_TASKS"/>

    <application
        android:allowBackup="true"
        android:name="com.emildesign.sgreportmanager.SGRaportManagerAppObj"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@android:style/Theme.Black.NoTitleBar.Fullscreen">

        <activity
            android:name="com.emildesign.sgreportmanager.activities.LoginScrActivity"
            android:screenOrientation="landscape">

            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
        <activity
            android:name="com.emildesign.sgreportmanager.activities.ReportsTableActivity"
            android:screenOrientation="landscape">
        </activity>
        <activity
            android:name="com.emildesign.sgreportmanager.activities.ParametersActivity"
            android:screenOrientation="landscape">
        </activity>
        <activity android:name="com.crittercism.NotificationActivity"/>  
</application>

好吧,我找到了我的问题所在,我设置了:

well I found where my problem was, I set:

android:theme="@android:style/Theme.Black.NoTitleBar.Fullscreen" 

使我的应用程序全屏显示,这应用了数据选择器的旧样式,将其更改为:

to make my application full screen and this applied the old style of the data picker changing it to:

android:theme="@android:style/Theme.Holo.Light.NoActionBar.Fullscreen"

创建以下 DataPicker:

Creates the following DataPicker:

比以前好多了,但这仍然不是我想要的结果.

It's better then before but this is still not the result I'm looking for.

推荐答案

将您的 android:targetSdkVersion 设置为 11 或更高.这是一个演示此内容的示例应用.

Set your android:targetSdkVersion to be 11 or higher. Here is a sample application demonstrating this.

更新

首先,您的原始 DatePicker 屏幕截图来自深色主题(例如 Theme.Holo),而您的第二个屏幕截图来自浅色主题(例如 Theme.Holo.Light).

First, your original DatePicker screenshot is from a dark theme (e.g., Theme.Holo), whereas your second screenshot is from a light theme (e.g., Theme.Holo.Light).

其次,DatePicker 文档有以下开头段落:

Second, the DatePicker documentation has the following opening paragraph:

这个类是一个用于选择日期的小部件.可以通过年、月和日微调器或 CalendarView 选择日期.一组微调器和日历视图会自动同步.客户端可以自定义是只显示微调器,还是只显示日历视图,或两者都显示.还可以自定义选择日期的最小和最大日期.

您可以通过android:calendarViewShown(或setCalendarViewShown())去掉CalendarView.当您尝试这样做时,您会发现一旦 CalendarView 消失,您的年份微调器就会出现.

You can get rid of the CalendarView via android:calendarViewShown (or setCalendarViewShown()). When you try that, you will find that your year spinner will appear once the CalendarView is gone.
