最近到4412最基本的都调了　然后觉得没事做了　所以增加一个HDMI的设置　不能闲着

以下使用的是广州斯道的icool210开发板　源码修改如下

最开始我是先在设置里加上这些设置然后在去实现功能　这里就一起说了　之前android2.3里有HDMI设置所以这里就参照那个增加　首先修改Setting

查看libhdmi库首先查看下hdmi能设置的格式源码路径

device/samsung/common/s5p/libhdmi/SecHdmi.cpp

你会发现有如下代码

    mHdmiResolutionValueList[0]  = 1080960;    mHdmiResolutionValueList[1]  = 1080950;    mHdmiResolutionValueList[2]  = 1080930;    mHdmiResolutionValueList[3]  = 1080160;    mHdmiResolutionValueList[4]  = 1080150;    mHdmiResolutionValueList[5]  = 720960;    mHdmiResolutionValueList[6]  = 720950;    mHdmiResolutionValueList[7]  = 5769501;    mHdmiResolutionValueList[8]  = 5769502;    mHdmiResolutionValueList[9]  = 4809601;    mHdmiResolutionValueList[10] = 4809602;

ResolutionValue根据这个我们大致知道了支持了格式下面来修改Setting

源码路径 packages/apps/Settings/res/values/arrays.xml

增加如下代码

   <!-- TV Out settings. -->    <string-array name="tv_resolution_entries"><item>1080P_60</item><item>1080P_50</item><item>1080P_30</item><item>1080I_60</item><item>1080I_50</item><item>720P_60</item><item>720P_50</item><item>576P_50_16_9</item><item>576P_50_4_3</item><item>480P_60_16_9</item><item>480P_60_4_3</item>    </string-array>    <!-- Do not translate. -->    <string-array name="tv_resolution_values" translatable="false"><!-- Do not translate. --><item>1080960</item><!-- Do not translate. --><item>1080950</item><!-- Do not translate. --><item>1080930</item><!-- Do not translate. --><item>1080160</item><!-- Do not translate. --><item>1080150</item><!-- Do not translate. --><item>720960</item><!-- Do not translate. --><item>720950</item><!-- Do not translate. --><item>5769501</item><!-- Do not translate. --><item>5769502</item><!-- Do not translate. --><item>4809601</item><!-- Do not translate. --><item>4809602</item>    </string-array>    <!-- TV Out settings. -->    <string-array name="tv_hdcp_entries"><item>Disable</item><item>Enable</item>    </string-array>    <!-- Do not translate. --><string-array name="tv_hdcp_values" translatable="false"><!-- Do not translate. --><item>0</item><!-- Do not translate. --><item>1</item>    </string-array>    <!-- TV Out settings. -->    <string-array name="tv_mode_entries"><item>HDMI(YCbCr)</item><item>HDMI(RGB)</item><item>DVI</item>    </string-array>    <!-- Do not translate. -->    <string-array name="tv_mode_values" translatable="false"><!-- Do not translate. --><item>0</item><!-- Do not translate. --><item>1</item><!-- Do not translate. --><item>2</item>    </string-array>

源码路径　packages/apps/Settings/res/values/strings.xml

增加如下内容

    <!-- Sound & display settings screen, setting option name to change TV Mode -->    <string name="tv_mode">TV Mode</string>    <!-- Sound & display settings screen, setting option summary to change TV Mode -->    <string name="tv_mode_summary">Choose TV out mode</string>    <!-- Sound & display settings screen, setting option name to change TV Resolution -->    <string name="tv_resolution">TV Resolution</string>    <!-- Sound & display settings screen, setting option summary to change TV Resolution -->    <string name="tv_resolution_summary">Choose TV resolution</string>    <!-- Sound & display settings screen, setting option name to change TV HDCP -->    <string name="tv_hdcp">TV HDCP</string>    <!-- Sound & display settings screen, setting option summary to change TV HDCP -->    <string name="tv_hdcp_summary">Enable HDMI HDCP</string>

源码路径 packages/apps/Settings/res/xml/display_settings.xml

增加如下内容

<ListPreferenceandroid:key="tv_mode"android:title="@string/tv_mode"android:summary="@string/tv_mode_summary"android:persistent="false"android:entries="@array/tv_mode_entries"android:entryValues="@array/tv_mode_values" /><ListPreferenceandroid:key="tv_resolution"android:title="@string/tv_resolution"android:summary="@string/tv_resolution_summary"android:persistent="false"android:entries="@array/tv_resolution_entries"android:entryValues="@array/tv_resolution_values" /><ListPreferenceandroid:key="tv_hdcp"android:title="@string/tv_hdcp"android:summary="@string/tv_hdcp_summary"android:persistent="false"android:entries="@array/tv_hdcp_entries"android:entryValues="@array/tv_hdcp_values" />

接着修改framework

源码路径:frameworks/base/core/java/android/provider/Settings.java　

增加如下内容:

        /**         * The tv out mode.         */        public static final String TV_MODE = "tv_mode";        /**         * The tv out resolution.         */        public static final String TV_RESOLUTION = "tv_resolution";        /**         * The tv out mode.         */        public static final String TV_HDCP = "tv_hdcp";

接着在这个文件里搜所SCREEN_OFF_TIMEOUT

会在public static final String[] SETTINGS_TO_BACKUP这个数组里找到一个　然后在它下面增加如下

            TV_MODE,            TV_RESOLUTION,            TV_HDCP,

按照我的理解这里应该是用来保存数据到数据库的　然后系统再次启动后设置还能保存

接着增加调用hdmi相关函数的接口这里我是直接把2.3的拷过来然后进行的修改

创建相应目录增加以下文件frameworks/base/slsi/java/com/slsi/sec/android/HdmiService.java

内容如下

package com.slsi.sec.android;public class HdmiService{    static {        System.loadLibrary("hdmiservice_jni");    }    public native void setHdmiCableStatus(int status);    public native void setHdmiMode(int mode);    public native void setHdmiResolution(int resolution);    public native void setHdmiHdcp(int enHdcp);    public native void initHdmiService();}

增加以下文件frameworks/base/slsi/jni/Android.mk

内容如下

LOCAL_PATH:= $(call my-dir)include $(CLEAR_VARS)LOCAL_SRC_FILES:= \    com_slsi_sec_android_HdmiService.cpp \    onload.cppLOCAL_C_INCLUDES += \$(JNI_H_INCLUDE)LOCAL_SHARED_LIBRARIES := \    libcutils \    libandroid_runtime \    libnativehelperifeq ($(S5P_BOARD_USES_HDMI),true)LOCAL_C_INCLUDES += \    device/samsung/common/s5p/libhdmiLOCAL_SHARED_LIBRARIES += libhdmiclientLOCAL_CFLAGS     += -DBOARD_USES_HDMIendifLOCAL_PRELINK_MODULE := falseifeq ($(TARGET_SIMULATOR),true)ifeq ($(TARGET_OS),linux)ifeq ($(TARGET_ARCH),x86)LOCAL_LDLIBS += -lpthread -ldl -lrtendifendifendififeq ($(WITH_MALLOC_LEAK_CHECK),true)LOCAL_CFLAGS += -DMALLOC_LEAK_CHECKendifLOCAL_MODULE_TAGS := optional engLOCAL_MODULE:= libhdmiservice_jniinclude $(BUILD_SHARED_LIBRARY)

增加以下文件frameworks/base/slsi/jni/com_slsi_sec_android_HdmiService.cpp

内容如下

#define LOG_TAG "HDMIStatusService"#include "jni.h"#include "JNIHelp.h"#include <cutils/log.h>#if defined(BOARD_USES_HDMI)#include "SecHdmiClient.h"#endifnamespace android {/* * Class:     com_slsi_sec_android_HdmiService * Method:    setHdmiCableStatus * Signature: (I)V */static void com_slsi_sec_android_HdmiService_setHdmiCableStatus  (JNIEnv *env, jobject obj, jint i){    int result = 0;#if defined(BOARD_USES_HDMI)    //LOGD("%s HDMI status: %d", __func__, i);    (SecHdmiClient::getInstance())->setHdmiCableStatus(i);#else    return;#endif    //return result;}/* * Class:     com_slsi_sec_android_setHdmiMode * Method:    setHdmiMode * Signature: (I)V */static void com_slsi_sec_android_HdmiService_setHdmiMode  (JNIEnv *env, jobject obj, jint i){    int result = 0;#if defined(BOARD_USES_HDMI)    (SecHdmiClient::getInstance())->setHdmiMode(i);#else    return;#endif}/* * Class:     com_slsi_sec_android_setHdmiResolution * Method:    setHdmiResolution * Signature: (I)V */static void com_slsi_sec_android_HdmiService_setHdmiResolution(JNIEnv *env, jobject obj, jint i){    int result = 0;#if defined(BOARD_USES_HDMI)    (SecHdmiClient::getInstance())->setHdmiResolution(i);#else    return;#endif}/* * Class:     com_slsi_sec_android_setHdmiHdcp * Method:    setHdmiHdcp * Signature: (I)V */static void com_slsi_sec_android_HdmiService_setHdmiHdcp(JNIEnv *env, jobject obj, jint i){    int result = 0;#if defined(BOARD_USES_HDMI)    (SecHdmiClient::getInstance())->setHdmiHdcp(i);#else    return;#endif}/* * Class:     com_slsi_sec_android_HdmiService * Method:    initHdmiService * Signature: ()V */static void com_slsi_sec_android_HdmiService_initHdmiService  (JNIEnv *env, jobject obj){#if defined(BOARD_USES_HDMI)    LOGI("%s ", __func__);    //(SecHdmiClient::getInstance())->init();#else    return;#endif    //return result;}static JNINativeMethod gMethods[] = {    {"setHdmiCableStatus", "(I)V", (void*)com_slsi_sec_android_HdmiService_setHdmiCableStatus},    {"setHdmiMode", "(I)V", (void*)com_slsi_sec_android_HdmiService_setHdmiMode},    {"setHdmiResolution", "(I)V", (void*)com_slsi_sec_android_HdmiService_setHdmiResolution},    {"setHdmiHdcp", "(I)V", (void*)com_slsi_sec_android_HdmiService_setHdmiHdcp},    {"initHdmiService", "()V", (void*)com_slsi_sec_android_HdmiService_initHdmiService},};int register_com_samsung_sec_android_HdmiService(JNIEnv* env){     jclass clazz = env->FindClass("com/slsi/sec/android/HdmiService");     if (clazz == NULL)     {         LOGE("Can't find com/slsi/sec/android/HdmiService");         return -1;     }     return jniRegisterNativeMethods(env, "com/slsi/sec/android/HdmiService",                                     gMethods, NELEM(gMethods));}} /* namespace android */

增加如下文件:frameworks/base/slsi/jni/onload.cpp

内容如下

#include "JNIHelp.h"#include "jni.h"#include "utils/Log.h"#include "utils/misc.h"namespace android {int register_com_samsung_sec_android_HdmiService(JNIEnv* env);};using namespace android;extern "C" jint JNI_OnLoad(JavaVM* vm, void* reserved){    JNIEnv* env = NULL;    jint result = -1;    if (vm->GetEnv((void**) &env, JNI_VERSION_1_4) != JNI_OK) {        LOGE("GetEnv failed!");        return result;    }    LOG_ASSERT(env, "Could not retrieve the env!");    if(register_com_samsung_sec_android_HdmiService(env) == -1)        LOGE("%s register_com_samsung_sec_android_HdmiStatus is failed", __func__);    return JNI_VERSION_1_4;}

然后修改build/core/pathmap.mk

在FRAMEWORKS_BASE_SUBDIRS里增加slsi \

我们要让他启动的时候能能自动设置成设置的参数所以

接着修改frameworks/base/services/java/com/android/server/SystemServer.java

增加如下内容

import com.slsi.sec.android.HdmiService;import static android.provider.Settings.System.TV_MODE;import static android.provider.Settings.System.TV_RESOLUTION;import static android.provider.Settings.System.TV_HDCP;

private HdmiService mHdmiService;

然后在

 mContentResolver = context.getContentResolver();

之后增加如下代码

Slog.i(TAG, "HDMI Setting");mHdmiService = new HdmiService();mHdmiService.setHdmiMode(Settings.System.getInt(mContentResolver, TV_MODE, 0));mHdmiService.setHdmiResolution(Settings.System.getInt(mContentResolver, TV_RESOLUTION, 4809601));mHdmiService.setHdmiHdcp(Settings.System.getInt(mContentResolver, TV_HDCP, 0));

跟着最后修改Setting里的DisplaySetting

源码路径packages/apps/Settings/src/com/android/settings/DisplaySettings.java

增加如下内容

import com.slsi.sec.android.HdmiService;import static android.provider.Settings.System.TV_MODE;import static android.provider.Settings.System.TV_RESOLUTION;import static android.provider.Settings.System.TV_HDCP;

    private static final String KEY_TV_MODE = "tv_mode";    private static final String KEY_TV_RESOLUTION = "tv_resolution";    private static final String KEY_TV_HDCP = "tv_hdcp";    private static final int FALLBACK_TV_MODE_VALUE = 0;    private static final int FALLBACK_TV_RESOLUTION_VALUE = 4809601;    private static final int FALLBACK_TV_HDCP_VALUE = 0;    private HdmiService mHdmiService;

然后在onCreate增加如下代码

        ListPreference tvModePreference =            (ListPreference) findPreference(KEY_TV_MODE);        tvModePreference.setValue(String.valueOf(Settings.System.getInt(                        resolver, TV_MODE, FALLBACK_TV_MODE_VALUE)));        tvModePreference.setOnPreferenceChangeListener(this);        ListPreference tvResolutionPreference =            (ListPreference) findPreference(KEY_TV_RESOLUTION);        tvResolutionPreference.setValue(String.valueOf(Settings.System.getInt(                        resolver, TV_RESOLUTION, FALLBACK_TV_RESOLUTION_VALUE)));        tvResolutionPreference.setOnPreferenceChangeListener(this);        ListPreference tvHdcpPreference =            (ListPreference) findPreference(KEY_TV_HDCP);        tvHdcpPreference.setValue(String.valueOf(Settings.System.getInt(                        resolver, TV_HDCP, FALLBACK_TV_HDCP_VALUE)));        tvHdcpPreference.setOnPreferenceChangeListener(this);mHdmiService = new HdmiService();

接着在onPreferenceChange函数里增加如下内容

        if (KEY_TV_MODE.equals(key)) {            int value = Integer.parseInt((String) objValue);            try {                Settings.System.putInt(getContentResolver(),                        TV_MODE, value);            } catch (NumberFormatException e) {                Log.e(TAG, "could not persist tv mode setting", e);            }            mHdmiService.setHdmiMode(value);        }        if (KEY_TV_RESOLUTION.equals(key)) {            int value = Integer.parseInt((String) objValue);            try {                Settings.System.putInt(getContentResolver(),                        TV_RESOLUTION, value);            } catch (NumberFormatException e) {                Log.e(TAG, "could not persist tv resolution setting", e);            }            mHdmiService.setHdmiResolution(value);        }if (KEY_TV_HDCP.equals(key)) {            int value = Integer.parseInt((String) objValue);            try {                Settings.System.putInt(getContentResolver(),                        TV_HDCP, value);            } catch (NumberFormatException e) {                Log.e(TAG, "could not persist tv resolution setting", e);            }            mHdmiService.setHdmiHdcp(value);        }

基本上就搞定了最后如图所示

相关patch我也上传到了我的资源　不知道为啥没显示出来　需要的可以去下载
