二、

追蹤日志 ，發(fā)現(xiàn)

02-23 16:10:56.933? 4876? 4876 E AndroidRuntime: at com.android.settings.SecuritySettings$SecuritySubSettings.onCreate(SecuritySettings.java:1046)

這塊為空

三、查看代碼

private void createPreferenceHierarchy() {

? ? ? ? ? ? PreferenceScreen root = getPreferenceScreen();

? ? ? ? ? ? if (root != null) {

? ? ? ? ? ? ? ? root.removeAll();

? ? ? ? ? ? }

? ? ? ? ? ? root = null;

? ? ? ? ? ? final int resid = getResIdForLockUnlockSubScreen(getActivity(),

? ? ? ? ? ? ? ? ? ? new LockPatternUtils(getContext()),

? ? ? ? ? ? ? ? ? ? ManagedLockPasswordProvider.get(getContext(), MY_USER_ID));

? ? ? ? ? 1084 ? addPreferencesFromResource(resid);? 這個(gè)為空了

? ? ? ? ? ? // lock after preference

? ? ? ? ? ? mLockAfter = (TimeoutListPreference) findPreference(KEY_LOCK_AFTER_TIMEOUT);

? ? ? ? ? ? if (mLockAfter != null) {

? ? ? ? ? ? ? ? setupLockAfterPreference();

? ? ? ? ? ? ? ? updateLockAfterPreferenceSummary();

? ? ? ? ? ? }

? ? ? ? ? ? // visible pattern

? ? ? ? ? ? mVisiblePattern = (SwitchPreference) findPreference(KEY_VISIBLE_PATTERN);

四、解決方案，

一、增加int 類型的非空判斷處理


diff --git a/src/com/android/settings/SecuritySettings.java b/src/com/android/settings/SecuritySettings.java

index 4876541..0ab2fb9 100644

--- a/src/com/android/settings/SecuritySettings.java

+++ b/src/com/android/settings/SecuritySettings.java

@@ -1083,6 +1083,12 @@

? ? ? ? ? ? final int resid = getResIdForLockUnlockSubScreen(getActivity(),

? ? ? ? ? ? ? ? ? ? new LockPatternUtils(getContext()),

? ? ? ? ? ? ? ? ? ? ManagedLockPasswordProvider.get(getContext(), MY_USER_ID));

+

+? ? ? ? ? ? if (resid == 0) {

+? ? ? ? ? ? ? ? finish();

+? ? ? ? ? ? ? ? return;

+? ? ? ? ? ? }

+

? ? ? ? ? ? addPreferencesFromResource(resid);

? ? ? ? ? ? // lock after preference


二、增加異常捕獲


? ? ? ? ? ? try {

? ? ? ? ? ? ? ? addPreferencesFromResource(resid);

? ? ? ? ? ? } catch (Exception e) {

? ? ? ? ? ? ? ? Log.e(TAG, "getResIdForLockUnlockSubScreen resid = "+resid);

? ? ? ? ? ? }


五、問題解決。
