1、launcher的布局太居中，要想两边拉伸
<\packages\apps\Launcher2\res\values\dimens.xml>
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>
4、里面icon的大小：
<\packages\apps\Launcher2\res\values-sw600dp\dimens.xml>
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>
workspace两屏间距：
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>
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:x="2"
launcher:y="2"
launcher:title = "@string/application_name" >
launcher:packageName="com.android.deskclock"
launcher:container="1"
launcher:x="0"
launcher:y="0" />
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>
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
