launcher 总结:
1、launcher的布局太居中，要想两边拉伸

<\packages\apps\Launcher2\res\values\dimens.xml>    40dp    40dpapps tab栏的宽度（Launcher2 icon 数目、大小）\packages\apps\Launcher2\res\layout-sw720dp\workspace.xml>    launcher:cellCountX="10"    launcher:cellCountY="6"

2、或者不想改数目：

<\packages\apps\Launcher2\src\com\android\launcher2\AppsCustomizeTabHost.java>    protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {          mTabs.getLayoutParams().width = contentWidth + 108;

3、workspace、AppsCustomize的cell大小：

<\packages\apps\Launcher2\res\values-sw600dp\dimens.xml>    110dip    110dip     110dp    110dp

4、里面icon的大小：

<\packages\apps\Launcher2\res\values-sw600dp\dimens.xml>     80dp

5、workspace没有拖动，第二页第一个icon出现在第一页的最右边：

加大workspace的宽度，或间距：workspace的paddingLeft、paddingRight：<\packages\apps\Launcher2\res\values-sw600dp-land\dimens.xml>    50dip    50dip workspace两屏间距：100dp 修改workspace的字体大小：如果没有就添加：<\packages\apps\Launcher2\res\values-sw480dp\styles.xml>

6、加wallpaper：

1.<\packages\apps\Launcher2\res\values-sw600dp\wallpapers.xml>   加wallpaper的名字2.<\packages\apps\Launcher2\res\drawable-nodpi>   加如wallpaper

7、gallery的widget默认添加到workspace上：

<\packages\apps\Launcher2\res\xml\default_workspace.xml>         <\packages\apps\Gallery2\src\com\android\gallery3d\gadget\PhotoAppWidgetProvider.java>    @Override    public void onUpdate(Context context,              for (int id : appWidgetIds) {                if(id == 2){                     helper.setWidget(id,WidgetDatabaseHelper.TYPE_SHUFFLE, null);                                  }            }

8、在桌面上添加网页的快捷方式：

<\packages\apps\Launcher2\res\xml\default_workspace.xml>

9、在桌面上默认放文件夹：

<\packages\apps\Launcher2\res\xml\default_workspace.xml>

10、桌面上添加快捷方式，点击播放视频：

<\packages\apps\Launcher2\res\xml-sw720dp\default_workspace.xml>

11、安装apk，显示隐藏的google play：

1.写google显示的apk:GooglePlayShow的activity：        ComponentName componentname = new ComponentName("com.android.vending", "com.android.vending.AssetBrowserActivity");        packagemanager.setComponentEnabledSetting(componentname, 1, 1);                 componentname = new ComponentName("com.example.googleplayshow", "com.example.googleplayshow.MainActivity");        packagemanager.setComponentEnabledSetting(componentname, 2, 1); 2.<\packages\apps\Launcher2\src\com\android\launcher2\LauncherModel.java>            } else if (Intent.ACTION_PACKAGE_ADDED.equals(action)) {                if (!replacing) {                         if(packageName.equals("com.example.googleplayshow")){                              context.startActivity(new Intent().setComponent(new ComponentName("com.example.googleplayshow", "com.example.googleplayshow.MainActivity")).setFlags(Intent.FLAG_ACTIVITY_NEW_TASK));                         }                    op = PackageUpdatedTask.OP_ADD;                } else {                    op = PackageUpdatedTask.OP_UPDATE;                }            } 隐藏google search：<\packages\apps\Launcher2\src\com\android\launcher2\Launcher.java>    private void setupViews() {        mSearchDropTargetBar = (SearchDropTargetBar) mDragLayer.findViewById(R.id.qsb_bar);        mSearchDropTargetBar.hideSearchBar(false);     void showWorkspace(boolean animated, Runnable onCompleteRunnable) {        //mSearchDropTargetBar.showSearchBar(wasInSpringLoadedMode);

12、widget中隐藏google play：

<\packages\apps\Launcher2\src\com\android\launcher2\AppsCustomizePagedView.java>updatePackages里面添加：if(!widget.provider.getPackageName().equals("com.android.vending") && !widget.provider.getPackageName().equals("com.android.vending.MarketWidgetProvider")){    mWidgets.add(widget);}

13、clock的widget下部分显示不全，向上调

<\packages\amlogic\Launcher2\res\values\dimens.xml>10dp 修改widget的text的size：<\packages\amlogic\Launcher2\res\layout\apps_customize_widget.xml>

14、launcher中隐藏一个app：

需要该app的packageName，例如要隐藏settings：<\packages\apps\Launcher2\src\com\android\launcher2\LauncherModel.java>        private void loadAllAppsByBatch() {                     apps = packageManager.queryIntentActivities(mainIntent, 0);                      ResolveInfo removeApp = null;                    for(ResolveInfo info:apps){                        if(info.activityInfo.packageName.equals("com.android.settings")){                                removeApp = info;                        }                     }                     if(removeApp != null){                        apps.remove(removeApp);                    }

15、launcher中隐藏多个app：红色为改动部分

<\packages\apps\Launcher2\src\com\android\launcher2\LauncherModel.java>      private void loadAllAppsByBatch() {     final PackageManager packageManager = mContext.getPackageManager();            List apps = new ArrayList();            List allApps = null;              int N = Integer.MAX_VALUE;             int startIndex;            int i=0;            int batchSize = -1;            while (i < N && !mStopped) {                if (i == 0) {                    mAllAppsList.clear();                    final long qiaTime = DEBUG_LOADERS ? SystemClock.uptimeMillis() : 0;                     allApps = packageManager.queryIntentActivities(mainIntent, 0);                    for(ResolveInfo info : allApps){                        if(info.activityInfo != null                                 && !info.activityInfo.packageName.equalsIgnoreCase("com.android.email")                                && !info.activityInfo.packageName.equalsIgnoreCase("com.android.providers.downloads.ui")                                && !info.activityInfo.packageName.equalsIgnoreCase("com.adobe.flashplayer")){                            apps.add(info);                        }                    }

settings 问题总结:

1.入口，设置分屏显示

frameworks\base\core\res\res\values\bools.xml 下的 preferences_prefer_dual_pane 为true.true

2.top level headers--这里可以去掉左边的headers

private void updateHeaderList(List target) {if (!getPackageManager().hasSystemFeature(PackageManager.FEATURE_BLUETOOTH)) {   target.remove(header);}

3.默认字体：

public void readFontSizePreference(ListPreference pref) {     ActivityManagerNative.getDefault().getConfiguration() 系统的Configuration是从ActivityManagerService设置的： <\frameworks\base\services\java\com\android\server\am\ActivityManagerService.java>mConfiguration.setToDefaults();fontScale = Float.parseFloat(SystemProperties.get("ro.fontScale","1"));

4.settings的theme:

<\packages\apps\Settings\AndroidManifest.xml>     <\frameworks\base\core\res\res\values\themes.xml>
