修改seting里面的休眠时间列表

去掉15秒和30秒 这个是数组具体值

1，在Z:\myandroid\packages\apps\Settings\res\values\arrays.xml

<string-array name="screen_timeout_values" translatable="false">

<!-- Do not translate. -->

<item>60000</item>

<!-- Do not translate. -->

<item>120000</item>

<!-- Do not translate. -->

<item>300000</item>

<!-- Do not translate. -->

<item>600000</item>

<!-- Do not translate. -->

<item>1800000</item>

</string-array>

添加的话也可以在里面添加item即可。

----------下面是界面显示的值----------------------

<string-array name="screen_timeout_entries">

<item msgid="7589406073232279088">"1 分钟"</item>

<item msgid="7001195990902244174">"2 分钟"</item>

<item msgid="7489864775127957179">"5 分钟"</item>

<item msgid="2314124409517439288">"10 分钟"</item>

<item msgid="6864027152847611413">"30 分钟"</item>

</string-array>

2，超时响应，默认的是超时休眠，我们可以修改默认的超时响应，做自己的事情，文件位置

Z:\myandroid\frameworks\base\services\java\com\android\server\power\PowerManagerService.java

private final class PowerManagerHandler extends Handler {

public PowerManagerHandler(Looper looper) {

super(looper, null, true /*async*/);

}

@Override

public void handleMessage(Message msg) {

switch (msg.what) {

case MSG_USER_ACTIVITY_TIMEOUT:

// handleUserActivityTimeout();/默认的处理方式

// wdh add 添加自己要做的事情

try{

Intent intent = mContext.getPackageManager().getLaunchIntentForPackage("com.android.lockscreen");

mContext.startActivity(intent);

}catch(Exception e){

}

break;

case MSG_SANDMAN:

handleSandman();

break;

case MSG_SCREEN_ON_BLOCKER_RELEASED:

handleScreenOnBlockerReleased();

break;

case MSG_CHECK_IF_BOOT_ANIMATION_FINISHED:

checkIfBootAnimationFinished();

break;

}

}

}

安卓M版本如何在setting中的休眠模式下添加永不休眠功能？

在alps\frameworks\base\packages\SettingsProvider\res\values\defaults.xml中设置def_screen_off_timeout为0，即

<integer name="def_screen_off_timeout">0</integer>

同时请注意，经由下面的操作，setting里面休眠时间的Never菜单才会出来：

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>

修改对比语言value文件夹下的arrays.xml, 修改screen_timeout_entries对应的翻译。不用管那个msgid，只是google用来表示是他自己的资源而已，直接添加<item >"不灭"</item>即可，请知悉。

（2）与L版本第二步一致，只是修改判断的是否为0，文件位置framework/base/services/java/com/android/server/power/PowerManagerService.java：

private void updateUserActivitySummaryLocked(long now, int dirty) {

...

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;

}

...

}

（3）按照上述两步修改，是可以实现永不灭屏，但有个side-effect，设置永不休眠和keyguard的安全锁后，闹钟响应时闪屏，闪屏是因为keyguard在闹钟唤醒时会被调起。引起L和M的差别是在PhoneWindowManager.java中

private void updateLockScreenTimeout() {

...........

if (enable) {

if (localLOGV) Log.v(TAG, "setting lockscreen timer");

mHandler.postDelayed(mScreenLockTimeout, mLockScreenTimeout);

其中L上永不休眠时 mLockScreenTimeout是-1，所以这个ScreenLockTimeout子线程不会被执行，也就不会去锁屏。而M上由于mLockScreenTimeout等于0，所以立即锁屏，就会出现一下锁屏的画面。

所以再将此函数修改如下：

private void updateLockScreenTimeout() {

synchronized (mScreenLockTimeout) {

boolean enable = (mAllowLockscreenWhenOn && mAwake &&

mKeyguardDelegate != null && mKeyguardDelegate.isSecure());

if (mLockScreenTimerActive != enable) {

if (enable) {

if (localLOGV) Log.v(TAG, "setting lockscreen timer");

//add mtk

if(mLockScreenTimeout!=0){

mHandler.postDelayed(mScreenLockTimeout, mLockScreenTimeout);}

// end mtk

} else {

if (localLOGV) Log.v(TAG, "clearing lockscreen timer");

mHandler.removeCallbacks(mScreenLockTimeout);

}

mLockScreenTimerActive = enable;

}

}

}
