manifest 中是否添加了 你要打开MultiSimSettings 这个？

protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); addPreferencesFromResource(R.xml.multi_sim_settings); mVoice = (ListPreference) findPreference(KEY_VOICE); mVoice.setOnPreferenceChangeListener(this); mData = (ListPreference) findPreference(KEY_DATA); mData.setOnPreferenceChangeListener(this); mSms = (ListPreference) findPreference(KEY_SMS); mSms.setOnPreferenceChangeListener(this); mConfigSub = (PreferenceScreen) findPreference(KEY_CONFIG_SUB); mConfigSub.getIntent().putExtra(CONFIG_SUB, true); if (isAirplaneModeOn()) { Log.d(TAG, "Airplane mode is ON, grayout the config subscription menu!!!"); mConfigSub.setEnabled(false); } for (int subId = 0; subId < SubscriptionManager.NUM_SUBSCRIPTIONS; subId++) { subManager.registerForSubscriptionActivated(subId, mHandler, EVENT_SUBSCRIPTION_ACTIVATED, null); subManager.registerForSubscriptionDeactivated(subId, mHandler, EVENT_SUBSCRIPTION_DEACTIVATED, null); } } @Override protected void onResume() { super.onResume(); int count = subManager.getActiveSubscriptionsCount(); if (count == SUBSCRIPTION_DUAL_STANDBY) { mVoice.setEntries(R.array.multi_sim_entries_voice); mVoice.setEntryValues(R.array.multi_sim_values_voice); } else { mVoice.setEntries(R.array.multi_sim_entries_voice_without_prompt); mVoice.setEntryValues(R.array.multi_sim_values_voice_without_prompt); } mIsForeground = true; updateState(); } @Override

这是manifest <!-- Multi Sim (Subscription) Settings --> <activity android:name="MultiSimSettings" android:label="@string/multi_sim_settings_title" android:process="com.android.phone" android:configChanges="mcc|mnc" android:clearTaskOnLaunch="true"> <intent-filter> <action android:name="android.intent.action.MAIN" /> <action android:name="com.android.settings.MULTI_SIM_SETTINGS" /> <category android:name="android.intent.category.DEFAULT" /> <category android:name="android.intent.category.VOICE_LAUNCH" /> <category android:name="com.android.settings.SHORTCUT" /> </intent-filter> </activity>
