Android S 修改关于手机的logo

1.让图片加载生效

frameworks/base/packages/SettingsLib/LayoutPreference/res/layout/preference_about_phone.xml

<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/entity_header"
style="@style/EntityHeader"
android:layout_width="match_parent"
android:layout_height="wrap_content"

android:orientation="vertical">
<LinearLayout
android:id="@+id/entity_header_content"
android:layout_width="320dp"
android:layout_height="wrap_content"

android:orientation="vertical">

<ImageView
android:id="@+id/iv_about_phone"
android:layout_width="320dp"
android:layout_height="120dp"
android:scaleType="fitCenter"
android:src="@drawable/about_phone"
android:antialias="true"/>

</LinearLayout>

</LinearLayout>

图片布局文件的宽高根据实际的来调！

2.手机设置关于手机菜单添加：

vendor/mediatek/proprietary/packages/apps/MtkSettings/res/xml/my_device_info.xml

<PreferenceScreen
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:settings="http://schemas.android.com/apk/res-auto"
android:key="my_device_info_pref_screen"
android:title="@string/about_settings">

<com.android.settingslib.widget.LayoutPreference
android:key="my_device_info_header"
android:order="0"
android:layout="@layout/settings_entity_header"
android:selectable="false"
settings:isPreferenceVisible="false"/>

<PreferenceCategory
android:key="basic_info_category"
android:selectable="false"
android:title="@string/my_device_info_basic_info_category_title">

<com.android.settingslib.widget.LayoutPreference
android:key="about_phone_category"
android:order="0"
android:layout="@layout/preference_about_phone"
android:selectable="false"
settings:isPreferenceVisible="true"/>
