介绍

因为做的是学生机，客户不希望相册的图片可以编辑。

分析

通过字符串我们找到了几个资源文件，以下只展示其中一个

路径：vendor/mediatek/proprietary/packages/apps/Gallery2/res/menu/operation.xml

    <item android:id="@+id/action_edit"android:title="@string/edit"android:showAsAction="never"android:visible="false" />

接着我们通过id排查，看是由哪个JAVA文件调用了该ID,到这里我们发现是在updateSupportedMenuEnabled调用了该项，这里有个if条件supportEdit，这里是通过MediaObject.SUPPORT_EDIT的值来判断是否启用。

路径：vendor/mediatek/proprietary/packages/apps/Gallery2/src/com/android/gallery3d/ui/MenuExecutor.java

    public static void updateSupportedMenuEnabled(Menu menu, int supported, boolean enabled) {boolean supportDelete = (supported & MediaObject.SUPPORT_DELETE) != 0;boolean supportRotate = (supported & MediaObject.SUPPORT_ROTATE) != 0;boolean supportCrop = (supported & MediaObject.SUPPORT_CROP) != 0;boolean supportShare = (supported & MediaObject.SUPPORT_SHARE) != 0;boolean supportSetAs = (supported & MediaObject.SUPPORT_SETAS) != 0;boolean supportShowOnMap = (supported & MediaObject.SUPPORT_SHOW_ON_MAP) != 0;boolean supportCache = (supported & MediaObject.SUPPORT_CACHE) != 0;boolean supportEdit = (supported & MediaObject.SUPPORT_EDIT) != 0;boolean supportInfo = (supported & MediaObject.SUPPORT_INFO) != 0;//add for Bluetooth Print featureboolean supportPrint = (supported & MediaObject.SUPPORT_PRINT) != 0;if (supportDelete) {setMenuItemEnable(menu, R.id.action_delete, enabled);}if (supportRotate) {setMenuItemEnable(menu, R.id.action_rotate_ccw, enabled);setMenuItemEnable(menu, R.id.action_rotate_cw, enabled);}if (supportCrop) {setMenuItemEnable(menu, R.id.action_crop, enabled);}if (supportShare) {setMenuItemEnable(menu, R.id.action_share, enabled);}if (supportSetAs) {setMenuItemEnable(menu, R.id.action_setas, enabled);}if (supportShowOnMap) {setMenuItemEnable(menu, R.id.action_show_on_map, enabled);}if (supportEdit) {setMenuItemEnable(menu, R.id.action_edit, enabled);}if (supportInfo) {setMenuItemEnable(menu, R.id.action_details, enabled);}}

修改

我们只需将SUPPORT_EDIT 的值改为0即可，编译后查看编辑功能确实消失了。
