添加HDMI分辨率和屏幕旋转

一、Android修改 1、文件AndroidManifest.xml 位置：packages\apps\Settings\AndroidManifest.xml 找到以下内容： <!-- HDMI --> <activity android:name="Settings$HdmiSettingsActivity" android:label="@string/hdmi" android:taskAffinity=""> <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.DEFAULT" /> <category android:name="android.intent.category.VOICE_LAUNCH" /> <category android:name="com.android.settings.SHORTCUT" /> </intent-filter> <meta-data android:name="com.android.settings.FRAGMENT_CLASS" android:value="com.android.settings.HdmiSettings" /> <meta-data android:name="com.android.settings.PRIMARY_PROFILE_CONTROLLED" android:value="true" /> </activity> <receiver android:name="HdmiReceiver"> <intent-filter android:priority="1000"> <action android:name="android.intent.action.HDMI_PLUG"/> <action android:name="android.intent.action.BOOT_COMPLETED" /> </intent-filter> </receiver> 修改为以下内容： <!-- HDMI --> <activity android:name="Settings$HdmiSettingsActivity" android:label="@string/hdmi" android:icon="@drawable/ic_settings_hdmi" android:taskAffinity="com.android.settings" android:parentActivityName="Settings"> <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.DEFAULT" /> <category android:name="android.intent.category.VOICE_LAUNCH" /> <category android:name="com.android.settings.SHORTCUT" /> </intent-filter> <intent-filter android:priority="8"> <action android:name="com.android.settings.action.SETTINGS" /> </intent-filter> <meta-data android:name="com.android.settings.category" android:value="com.android.settings.category.device" /> <meta-data android:name="com.android.settings.FRAGMENT_CLASS" android:value="com.android.settings.HdmiSettings" /> <meta-data android:name="com.android.settings.PRIMARY_PROFILE_CONTROLLED" android:value="true" /> </activity> <receiver android:name="HdmiReceiver"> <intent-filter android:priority="1000"> <action android:name="android.intent.action.HDMI_PLUG"/> <action android:name="android.intent.action.BOOT_COMPLETED" /> </intent-filter> </receiver> 2、文件DisplaySettings.java 位置：packages\apps\Settings\src\com\android\settings\DisplaySettings.java 找到以下内容： @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); mProduct = SystemProperties.get("ro.target.product"); String supportHDMI = SystemProperties.get("ro.rk.hdmi_enable", "false"); final Activity activity = getActivity(); final ContentResolver resolver = activity.getContentResolver(); addPreferencesFromResource(R.xml.display_settings); mHDMIPreference = findPreference(KEY_HDMI_SETTINGS); if(!"tablet".equals(mProduct) || !"true".equals(supportHDMI)){ getPreferenceScreen().removePreference(mHDMIPreference); } 修改为以下内容： @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); mProduct = SystemProperties.get("ro.target.product"); String supportHDMI = SystemProperties.get("ro.rk.hdmi_enable", "false"); final Activity activity = getActivity(); final ContentResolver resolver = activity.getContentResolver(); addPreferencesFromResource(R.xml.display_settings); mHDMIPreference = findPreference(KEY_HDMI_SETTINGS); if("tablet".equals(mProduct) || "true".equals(supportHDMI)){ getPreferenceScreen().removePreference(mHDMIPreference); } 3、文件HdmiSettings.java 位置：packages\apps\Settings\src\com\android\settings\HdmiSettings.java 找到以下内容： import android.hardware.display.DisplayManager; import android.view.Display; import android.view.IWindowManager; import android.view.Surface; import android.os.ServiceManager; public class HdmiSettings extends SettingsPreferenceFragment implements OnPreferenceChangeListener, SwitchBar.OnSwitchChangeListener, Preference.OnPreferenceClickListener { /** * Called when the activity is first created. */ private static final String TAG = "HdmiSettings"; private static final String KEY_HDMI_RESOLUTION = "hdmi_resolution"; private static final String KEY_HDMI_SCALE = "hdmi_screen_zoom"; private static final String KEY_HDMI_ROTATION="hdmi_rotation"; 修改为以下内容： import android.hardware.display.DisplayManager; import android.view.Display; public class HdmiSettings extends SettingsPreferenceFragment implements OnPreferenceChangeListener, SwitchBar.OnSwitchChangeListener, Preference.OnPreferenceClickListener { /** * Called when the activity is first created. */ private static final String TAG = "HdmiSettings"; private static final String KEY_HDMI_RESOLUTION = "hdmi_resolution"; private static final String KEY_HDMI_SCALE = "hdmi_screen_zoom"; 再找到以下内容： private ListPreference mHdmiResolution; private ListPreference mHdmiRotation; private Preference mHdmiScale; 修改为以下内容： private ListPreference mHdmiResolution; private Preference mHdmiScale; 再找到以下内容： private DisplayManager mDisplayManager; private DisplayListener mDisplayListener; private IWindowManager wm; 修改为以下内容： private DisplayManager mDisplayManager; private DisplayListener mDisplayListener; 再找到以下内容： @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); IntentFilter filter = new IntentFilter("android.intent.action.HDMI_PLUGGED"); getContext().registerReceiver(HdmiListener, filter); context = getActivity(); mDisplayManager = (DisplayManager) context.getSystemService(Context.DISPLAY_SERVICE); mDisplayListener = new DisplayListener(); mStrPlatform = SystemProperties.get("ro.board.platform"); mDisplayInfo = getDisplayInfo(); addPreferencesFromResource(R.xml.hdmi_settings_timeout); mHdmiResolution = (ListPreference) findPreference(KEY_HDMI_RESOLUTION); mHdmiResolution.setOnPreferenceChangeListener(this); mHdmiResolution.setOnPreferenceClickListener(this); if (mDisplayInfo != null) { mHdmiResolution.setEntries(DrmDisplaySetting.getDisplayModes(mDisplayInfo).toArray(new String[0])); mHdmiResolution.setEntryValues(DrmDisplaySetting.getDisplayModes(mDisplayInfo).toArray(new String[0])); }
