android动态壁纸的制作
?對于Android 2.1來說Live Wallpapers動態壁紙的加入為Android桌面加入了更好的動態效果。如何開發一個Android動態桌面呢? 下面Android123給大家一個詳細的步驟創建屬于你自己的Live Wallpaper吧。
??1. 首先我使用Eclipse創建一個標準的Android工程這里package name我們使用cn.com.android123.cwj，然后進入工程的/res/文件夾，刪除layout這個文件夾，當然里面的main.xml也會被刪除的，對于Live Wallpaper來說傳統的布局文件是不需要的。
??2. 類似AppWidget一樣，我們可以加入動態壁紙的設置界面，我們在/res/文件夾中新建一個名為xml的文件夾，新建一個utf8編碼的xml文件，名為livewallpaper.xml，內容為
???<?xml version="1.0" encoding="utf-8"?>
??<wallpaper xmlns:android="http://schemas.android.com/apk/res/android"
?android:settingsActivity="cn.com.android123.cwj.LiveWallpaperSettings"
?android:thumbnail="@drawable/icon"/>
???這里我們可以看到上面的節點名為wallpaper，而設置的界面為 cn.com.android123.cwj.LiveWallpaperSettings??這個Activity，而在添加動態壁紙時顯示圖標為/res/drawable/icon 這個文件，同時我們再創建一個xml文件用于LiveWallpaperSettings這個Activity的布局，我們起名為livewallpaper_settings.xml內容為
??<?xml version="1.0" encoding="utf-8"?>
<PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android"
?android:title="@string/livewallpaper_settings"
?android:key="livewallpaper_settings">
?<ListPreference
??android:key="livewallpaper_testpattern"
??android:title="標題"
??android:summary="簡單描述"
??android:entries="@array/livewallpaper_testpattern_names"
??android:entryValues="@array/livewallpaper_testpattern_prefix"/>
?<CheckBoxPreference android:key="livewallpaper_movement"
??android:summary="動態描述"
??android:title="動態標題"
??android:summaryOn="動態測試"
??android:summaryOff="靜止測試"/>
</PreferenceScreen>
??3. 創建一個名為LiveWallpaper的類作為動態壁紙的主類，從WallpaperService父類繼承，這里我們可以像寫標準Android服務那樣開發，代碼為
??public class LiveWallpaper extends WallpaperService
{
?public static final String?SHARED_PREFS_NAME?= "livewallpapersettings";
?@Override
?public void onCreate()
?{
??super.onCreate();
?}
?@Override

?{
??super.onDestroy();
?}
?@Override
?public Engine onCreateEngine()
?{
??return new TestPatternEngine();
?}
?class TestPatternEngine extends Engine implements

??TestPatternEngine()
??{
???final Paint paint = mPaint;
???paint.setColor(0xffffffff);
???paint.setAntiAlias(true);

???mPreferences = LiveWallpaper.this.getSharedPreferences(SHARED_PREFS_NAME, 0);

?}
}
?這里需要注意的是在androidmanifest.xml文件中加入
<service android:name=".LiveWallpaper" android:label="@string/app_name"?android:icon="@drawable/icon">
???<intent-filter>
??????<action android:name="android.service.wallpaper.WallpaperService" />
????</intent-filter>
????<meta-data android:name="android.service.wallpaper"?android:resource="@xml/livewallpaper" />
</service>
4. ??新建類LiveWallpaperSettings從 PreferenceActivity 繼承實現我們的設置界面，代碼如下
??public class LiveWallpaperSettings extends PreferenceActivity
?implements SharedPreferences.OnSharedPreferenceChangeListener
{
?@Override
?protected void onCreate(Bundle icicle)
?{
??super.onCreate(icicle);
??getPreferenceManager().setSharedPreferencesName(LiveWallpaper.SHARED_PREFS_NAME);
??addPreferencesFromResource(R.xml.livewallpaper_settings);
??getPreferenceManager().getSharedPreferences()
????.registerOnSharedPreferenceChangeListener(this);
?}
?
?@Override
?protected void onResume()
?{
??super.onResume();
?}
?@Override
?protected void onDestroy()
?{
??getPreferenceManager().getSharedPreferences()
????.unregisterOnSharedPreferenceChangeListener(this);
??super.onDestroy();
?}
?public void onSharedPreferenceChanged(SharedPreferences sharedPreferences,
???String key)
?{
?}
}
同時仍然在androidmanifest.xml中加入 下面的代碼。
<activity android:label="@string/livewallpaper_settings"
???android:name=".LiveWallpaperSettings"
???android:theme="@android:style/Theme.Light.WallpaperSettings"
???android:exported="true"
???android:icon="@drawable/icon">
??</activity>
5. 由于Android動態壁紙是2.1 API Level為7才加入的，所以設置好minSDK以及需要設備支持動態壁紙，我們在androidmanifest.xml中加入
?<uses-sdk android:minSdkVersion="7" />
?<uses-feature android:name="android.software.live_wallpaper" />
?6. 對于文中ListPreference用到的數組，及代碼中涉及的顏色數組，我們在/res/values/ 文件夾中創建一個名為testpatterns.xml 的文件，內容為
??<?xml version="1.0" encoding="utf-8"?>
<resources xmlns:xliff="urn:oasis:names:tc:xliff:document:1.2">
?<string-array name="livewallpaper_testpattern_names">
??<item>"Color Bars 16x9"</item>
??<item>"Color Bars 4x3"</item>
??<item>"EBU Color Bars"</item>
?</string-array>
?<string-array name="livewallpaper_testpattern_prefix">
??<item>"smpte"</item>
??<item>"bars"</item>
