来使能硬件模块。
-------------------------
目前做的项目,需要在系统settings里面添加一选项来使能硬件模块,里面涉及到的preference知识,请网上了解,这里记录下方法。
1,settings 应用一般在 目录:packagesappsSettings,我们先找到通话设置的布局位置,看看它在那个包路径下,进入packagesappsSettings esxml,打开settings.xml文件:
Java代码
<com.android.settings.IconPreferenceScreen
android:key="call_settings"
settings:icon="@drawable/ic_settings_call"
android:title="@string/call_settings_title">
<intent
android:action="android.intent.action.MAIN"
android:targetPackage="com.android.phone"
android:targetClass="com.android.phone.CallFeaturesSetting" />
</com.android.settings.IconPreferenceScreen>
<com.android.settings.IconPreferenceScreen
android:key="call_settings"
settings:icon="@drawable/ic_settings_call"
android:title="@string/call_settings_title">
<intent
android:action="android.intent.action.MAIN"
android:targetPackage="com.android.phone"
android:targetClass="com.android.phone.CallFeaturesSetting" />
</com.android.settings.IconPreferenceScreen>
android:targetPackage="com.android.phone"
android:targetClass="com.android.phone.CallFeaturesSetting"
targetPackage:表示包名,根据此我们可以找到通话设置的路径。
targetClass:表示此布局文件被那个类所引用,根据此类,我们可以知道在那个文件里面管理我们的通话设置功能。 www.5**.com
2.根据包名,我们可以看到在packagesappsPhone 目录下,进入 esxml目录下
找到通话布局文件:call_feature_setting.xml,根据类名,很容易找到布局文件。
里面内容如下:
Java代码
<PreferenceCategory android:key="button_misc_category_key"
android:title="@string/other_settings"
android:persistent="false" />
<!-- Dect settings -->
<PreferenceScreen
android:key="dect_settings"
android:title="@string/dect_module_title"
android:summary="@string/dect_module_title" >
<intent
android:action="android.intent.action.MAIN"
android:targetPackage="com.android.phone"
android:targetClass="com.android.phone.DectSettings" />
</PreferenceScreen>
<CheckBoxPreference
android:key="button_auto_retry_key"
android:title="@string/auto_retry_mode_title"
android:persistent="false"
android:summary="@string/auto_retry_mode_summary"/>
<PreferenceCategory android:key="button_misc_category_key"
android:title="@string/other_settings"
android:persistent="false" />
<!-- Dect settings -->
<PreferenceScreen
android:key="dect_settings"
android:title="@string/dect_module_title"
android:summary="@string/dect_module_title" >
<intent
android:action="android.intent.action.MAIN"
android:targetPackage="com.android.phone"
android:targetClass="com.android.phone.DectSettings" />
</PreferenceScreen>
<CheckBoxPreference
android:key="button_auto_retry_key"
android:title="@string/auto_retry_mode_title"
android:persistent="false"
android:summary="@string/auto_retry_mode_summary"/>
Dect setting 就是新添加进入的设置菜单,我们的原则尽量不大量修改,所以添加一个PreferenceScreen,新增一个类文件来管理DECt菜单选项。
android:targetPackage="com.android.phone"
android:targetClass="com.android.phone.DectSettings"
我们指明了包名,类名后,因这是个activity,所以我们需要到Phone目录下修改
AndroidManifest.xml文件,指明启动的activity的类名.
Java代码
<activity android:name="CdmaCallOptions"
android:label="@string/cdma_options">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
</intent-filter>
</activity>
<!-- dect activity -->
<activity android:name="DectSettings"
android:label="@string/dect_module_title">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
</intent-filter>
</activity>
<activity android:name="CdmaCallOptions"
android:label="@string/cdma_options">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
</intent-filter>
</activity>
<!-- dect activity -->
<activity android:name="DectSettings"
android:label="@string/dect_module_title">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
</intent-filter>
</activity>
3.修改好后,我们必须在此activity里添加preference布局文件。
在此目录Phone esxml下,新增dect_settings.xml
Java代码
<?xml version="1.0" encoding="utf-8"?>
<PreferenceScreen xmlns:android="http://schemas.a*****.com/apk/res/android"
android:title="@string/dect_module_title">
<CheckBoxPreference
android:key="button_dect_module_key"
android:title="@string/dect_module_title"
android:defaultValue="true"
android:summaryOn="@string/dect_module_start"
android:summaryOff="@string/dect_module_stop"
/>
</PreferenceScreen>
<?xml version="1.0" encoding="utf-8"?>
<PreferenceScreen xmlns:android="http://schemas.a*****.com/apk/res/android"
android:title="@string/dect_module_title">
<CheckBoxPreference
android:key="button_dect_module_key"
android:title="@string/dect_module_title"
android:defaultValue="true"
android:summaryOn="@string/dect_module_start"
android:summaryOff="@string/dect_module_stop"
/>
</PreferenceScreen>
好了,总体布局已经完成
4.在packagesappsPhonesrccomandroidphone目录下
新增DectSettings.java文件
加载布局文件:
//dect xml
addPreferencesFromResource(R.xml.dect_settings);
里面涉及到的MidPhoneServce服务,是自己添加的,主要通过此服务的AIDL接口跟硬件打交道。想了解系统服务,请网上查找资料。
