安卓系统定制常见问题解决

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. 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>
