1.修改framework/base/packages/SettingsProvider/res/values/defaults.xml中
def_screen_off_timeout默认值为0
2.修改framework/base/services/core/java/com/android/server/policy/PhoneWindowManager.java中
搜索关键字never screenOff
private void updateLockScreenTimeout() { synchronized (mScreenLockTimeout) { boolean enable = (mAllowLockscreenWhenOn && mAwake && mKeyguardDelegate != null && mKeyguardDelegate.isSecure(mCurrentUserId)); if (mLockScreenTimerActive != enable) { if (enable) { if (localLOGV) Log.v(TAG, "setting lockscreen timer"); mHandler.removeCallbacks(mScreenLockTimeout); // remove any pending requests //*/ add never screenOff if (mLockScreenTimeout != 0) { mHandler.postDelayed(mScreenLockTimeout, mLockScreenTimeout); } //*/ } else { if (localLOGV) Log.v(TAG, "clearing lockscreen timer"); mHandler.removeCallbacks(mScreenLockTimeout); } mLockScreenTimerActive = enable; } }}3…修改framework/base/service/core/java/com/android/server/power/PowerManagerService.java中
搜索关键字never screenOff
private void updateUserActivitySummaryLocked(long now, int dirty) { // Update the status of the user activity timeout timer. if ((dirty & (DIRTY_WAKE_LOCKS | DIRTY_USER_ACTIVITY | DIRTY_WAKEFULNESS | DIRTY_SETTINGS)) != 0) { mHandler.removeMessages(MSG_USER_ACTIVITY_TIMEOUT); long nextTimeout = 0; if (mWakefulness == WAKEFULNESS_AWAKE || mWakefulness == WAKEFULNESS_DREAMING || mWakefulness == WAKEFULNESS_DOZING) { final int sleepTimeout = getSleepTimeoutLocked(); final int screenOffTimeout = getScreenOffTimeoutLocked(sleepTimeout); final int screenDimDuration = getScreenDimDurationLocked(screenOffTimeout); final boolean userInactiveOverride = mUserInactiveOverrideFromWindowManager; final int screenButtonLightDuration = getButtonLightDurationLocked(screenOffTimeout); mUserActivitySummary = 0; if (mLastUserActivityTime >= mLastWakeTime) { if ( (mLastUserActivityButtonTime >= mLastWakeTime) && (now < mLastUserActivityButtonTime + screenButtonLightDuration) ) { mUserActivitySummary |= USER_ACTIVITY_BUTTON_BRIGHT; mUserActivitySummary |= USER_ACTIVITY_SCREEN_BRIGHT; nextTimeout = mLastUserActivityButtonTime + screenButtonLightDuration; } else if (now < mLastUserActivityTime + screenOffTimeout - screenDimDuration) { nextTimeout = mLastUserActivityTime + screenOffTimeout - screenDimDuration; mUserActivitySummary |= USER_ACTIVITY_SCREEN_BRIGHT; } else { nextTimeout = mLastUserActivityTime + screenOffTimeout; if (now < nextTimeout) { mUserActivitySummary |= USER_ACTIVITY_SCREEN_DIM; } } } if (mUserActivitySummary == 0 && mLastUserActivityTimeNoChangeLights >= mLastWakeTime) { nextTimeout = mLastUserActivityTimeNoChangeLights + screenOffTimeout; if (now < nextTimeout) { if (mDisplayPowerRequest.policy == DisplayPowerRequest.POLICY_BRIGHT) { mUserActivitySummary = USER_ACTIVITY_SCREEN_BRIGHT; } else if (mDisplayPowerRequest.policy == DisplayPowerRequest.POLICY_DIM) { mUserActivitySummary = USER_ACTIVITY_SCREEN_DIM; } } } if (mUserActivitySummary == 0) { if (sleepTimeout >= 0) { final long anyUserActivity = Math.max(mLastUserActivityTime, mLastUserActivityTimeNoChangeLights); if (anyUserActivity >= mLastWakeTime) { nextTimeout = anyUserActivity + sleepTimeout; if (now < nextTimeout) { mUserActivitySummary = USER_ACTIVITY_SCREEN_DREAM; } } } else { mUserActivitySummary = USER_ACTIVITY_SCREEN_DREAM; nextTimeout = -1; } } if (mUserActivitySummary != USER_ACTIVITY_SCREEN_DREAM && userInactiveOverride) { if ((mUserActivitySummary & (USER_ACTIVITY_SCREEN_BRIGHT | USER_ACTIVITY_SCREEN_DIM)) != 0) { // Device is being kept awake by recent user activity if (nextTimeout >= now && mOverriddenTimeout == -1) { // Save when the next timeout would have occurred mOverriddenTimeout = nextTimeout; } } mUserActivitySummary = USER_ACTIVITY_SCREEN_DREAM; nextTimeout = -1; } //*/ add never screenOff if (mScreenOffTimeoutSetting != 0) { if (mUserActivitySummary != 0 && nextTimeout >= 0) { Message msg = mHandler.obtainMessage(MSG_USER_ACTIVITY_TIMEOUT); msg.setAsynchronous(true); mHandler.sendMessageAtTime(msg, nextTimeout); } } else { mUserActivitySummary |= USER_ACTIVITY_SCREEN_BRIGHT; } //*/ } else { mUserActivitySummary = 0; } if (DEBUG_SPEW) { Slog.d(TAG, "updateUserActivitySummaryLocked: mWakefulness=" + PowerManagerInternal.wakefulnessToString(mWakefulness) + ", mUserActivitySummary=0x" + Integer.toHexString(mUserActivitySummary) + ", nextTimeout=" + TimeUtils.formatUptime(nextTimeout)); } }}4.修改packages/apps/Settings/res/values/arrays.xml
在screen_timeout_entries中添加一个item never
在screen_timeout_values中添加一个item 0
注意在添加这两个item时，要添加在第一项，避免出现无论选择多少时间，都显示永不休眠的bug
