Android顯示設定中增加“永不休眠”功能，android顯示設定

首先在frameworks\base\packages\SettingsProvider\res\values\defaults.xml中設定def_screen_off_timeout為-1，即
<integer name="def_screen_off_timeout">-1</integer>
然後修改alps\packages\apps\Settings\res\values\arrays.xml:

 <!-- Display settings.  The delay in inactivity before the screen is turned off. These are shown ain a list dialog. -->    <string-array name="screen_timeout_entries">        <item>15 seconds</item>        <item>30 seconds</item>        <item>1 minute</item>        <item>2 minutes</item>        <item>10 minutes</item>        <item>30 minutes</item>        <item>never</item>    </string-array>     <!-- Do not translate. -->   <string-array  name="screen_timeout_values" translatable="false">        <!-- Do not translate. -->        <item>15000</item>        <!-- Do not translate. -->        <item>30000</item>        <!-- Do not translate. -->        <item>60000</item>        <!-- Do not translate. -->        <item>120000</item>        <!-- Do not translate. -->        <item>600000</item>        <!-- Do not translate. -->        <item>1800000</item>         <item>-1</item>    </string-array>

接著修改對比語言value檔案夾下的arrays.xml, 修改screen_timeout_entries對應的翻譯。不用管那個msgid，只是google用來表示是他自己的資源而已，直接添加<item >"永不休眠"</item>即可。

然後是代碼的改動：

frameworks/base/services/java/com/android/server/power/PowerManagerService.java

private void updateUserActivitySummaryLocked(long now, int dirty) {..... //change code here ==============                      Slog.d(TAG,"mScreenOffTimeoutSetting ="+mScreenOffTimeoutSetting);                      //if (mUserActivitySummary != 0 ) {                if (mUserActivitySummary != 0 && mScreenOffTimeoutSetting > 0) {//change code here  end ==============                    Message msg = mHandler.obtainMessage(MSG_USER_ACTIVITY_TIMEOUT);                    msg.setAsynchronous(true);                    mHandler.sendMessageAtTime(msg, nextTimeout);                }
