Launcher 总结:

1、launcher的布局太居中，要想两边拉伸

<\packages\apps\Launcher2\res\values\dimens.xml>

apps_customize_pageLayoutPaddingLeft">40dp

apps_customize_pageLayoutPaddingRight">40dp

apps 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>

13sp

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>

            launcher:packageName=" com.android.gallery3d"
        launcher:className=" com.android.gallery3d.gadget.PhotoAppWidgetProvider"
        launcher:screen="2"
        launcher:x="1"
        launcher:y="0"
        launcher:spanX="3"
        launcher:spanY="3" />

<\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>

   launcher:title="@string/application_name"
        launcher:icon="@drawable/ic_no_applications"
        launcher:uri="http://www.aaa.com"
        launcher:screen="0"
        launcher:x="0"
        launcher:y="3" />

9、在桌面上默认放文件夹：

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

             launcher:screen="2"
          launcher:x="2"
          launcher:y="2"
          launcher:title = "@string/application_name" >


               launcher:className="com.android.deskclock.DeskClock"
          launcher:packageName="com.android.deskclock"
          launcher:container="1"
          launcher:x="0"
          launcher:y="0" />

               launcher:className="com.android.calculator2.Calculator"
          launcher:packageName="com.android.calculator2"
          launcher:container="1"
          launcher:x="0"
          launcher:y="0" />

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>

launcher:icon="@drawable/ic_launcher_application"

launcher:uri=" file:///mnt/sdcard/external_sdcard/1...playermenu;end"

launcher:screen="2"

launcher:x="1"

launcher:y="1" />

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>

android:id="@+id/widget_name"

android:textSize="20sp" />

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.

preferences_prefer_dual_pane">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>

               android:icon="@mipmap/ic_launcher_settings"
            android:taskAffinity=""
            android:theme="@android:style/ Theme.Holo"
            android:uiOptions="splitActionBarWhenNarrow"
            android:hardwareAccelerated="true">

<\frameworks\base\core\res\res\values\themes.xml>
