20250910在荣品RD-RK3588-MID开发板的Android13系统下修改短按power按键的休眠/唤醒为关闭/打开背光

2025/9/10 19:30

缘起：荣品RD-RK3588-MID开发板的Android13系统，短按power按键的时候休眠/唤醒不太正常。

还好，PM只需要在短按power按键时候是：为关闭/打开背光

还好，找到这篇博文，完美解决问题了。

不过本博文主题/主体正确，但是细节还是有些问题。

比如缺少一些头文件，还有就是编译问题，这些就交给DeepSeek来解决了！

RK3588 Android12 假休眠 power键只关背光触摸时唤醒亮屏

不知道啥原因，硬件要求按下Pwoer键是不要用系统层提供的关屏，要求不要断开mini信号，只关掉背光？？？

（一）

1、修改power键短按策略：

frameworks\base\core\res\res\values\config.xml

修改 config_shortPressOnPowerBehavior = 0

Z:\rk-android13-20250818RD-RK3588-MID\frameworks\base\core\res\res\values\config.xml

Y:\android13-20250818\frameworks\base\core\res\res\values\config.xml

<!-- Control the behavior when the user short presses the power button.

0 - Nothing
1 - Go to sleep (doze)
2 - Really go to sleep (don't doze)
3 - Really go to sleep and go home (don't doze)
4 - Go to home
5 - Dismiss IME if shown. Otherwise go to home
-->
<integer name="config_shortPressOnPowerBehavior">1</integer>

修改为：

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

2、修改Power事件：

frameworks/base/services/core/java/com/android/server/policy/PhoneWindowManager.java

Y:\android13-20250818\frameworks\base\services\core\java\com\android\server\policy\PhoneWindowManager.java

Z:\rk-android13-20250818RD-RK3588-MID\frameworks\base\services\core\java\com\android\server\policy\PhoneWindowManager.java

return;

}
switch (mShortPressOnPowerBehavior) {
case SHORT_PRESS_POWER_NOTHING:
switchBacklight();
break;

case SHORT_PRESS_POWER_GO_TO_SLEEP:

sleepDefaultDisplayFromPowerButton(eventTime, 0);

break;

case SHORT_PRESS_POWER_REALLY_GO_TO_SLEEP:

sleepDefaultDisplayFromPowerButton(eventTime,

if (sleepDefaultDisplayFromPowerButton(eventTime,

PowerManager.GO_TO_SLEEP_FLAG_NO_DOZE)) {

launchHomeFromHotKey(DEFAULT_DISPLAY);

}

break;

PhoneWindowManager类中新增以下代码：【加到最后面】

@Override

public Boolean parseState(ExtconInfo extconIfno, String state) {

// state: DP=1 or state: dp*=1

return (state.contains(NAME) && state.contains(EXIST))

|| state.contains(DP_EXIST);

}

// 2025/9/10 15:56 wenyuanbo Add RD-RK3588-MID
private static final String backlightGpio = "/sys/class/backlight/backlight/bl_power"; // PWM inverting, 0=screen on, 1=screen off
//GPIO4A0 BackLight 4*32+0*8+0=128
private static final String mipiSignalGpio = "/sys/class/gpio/gpio128/value"; // MIPI signal, 1=on, 0=off

private static void switchBacklight(){
int currentBacklight = readGpio(backlightGpio);
if(currentBacklight == 0){ // Currently, the screen is lit. Change it to black screen
writeGpio(backlightGpio, "1");
writeGpio(mipiSignalGpio, "0");
}else{
writeGpio(mipiSignalGpio, "1");
writeGpio(backlightGpio, "0");
}
}

private static void brightScreen(){
int currentBacklight = readGpio(backlightGpio);
if(currentBacklight != 0){
writeGpio(mipiSignalGpio, "1");
writeGpio(backlightGpio, "0");
}
}

private static boolean writeGpio(String filePath, String value){
File file = new File(filePath);
if(!file.exists()){
return false;
}

OutputStreamWriter ops = null;
try {
ops = new OutputStreamWriter(new FileOutputStream(file));
ops.write(value);
ops.flush();
return true;
} catch (Exception e) {
Log.e("GPIO", "write fail", e);
} finally {
if(ops != null){
try {
ops.close();
} catch (IOException e) {
}
}
}
return false;
}

private static int readGpio(String filePath){
File file = new File(filePath);
if(!file.exists()){
return -1;
}

BufferedReader br = null;
try {
br = new BufferedReader(new InputStreamReader(new FileInputStream(file)));
String line = br.readLine();
if(line != null){
return Integer.parseInt(line);
}
} catch (Exception e) {
Log.e("GPIO", "reader fail", e);
} finally {
if(br != null){
try {
br.close();
} catch (IOException e) {
}
}
}
return -1;
}

// 2025/9/10 17:22 wenyuanbo add Open Backlight

private WindowManagerPolicy.PointerEventListener mPointerEventListener = new WindowManagerPolicy.PointerEventListener() {

@Override

public void onPointerEvent(MotionEvent motionEvent) {

if(motionEvent.getAction() == MotionEvent.ACTION_DOWN){

brightScreen();

}

};

}

这是我们RK3588板子控制背光的GPIO节点和MIPI信号节点，由驱动工程师确认！

此时已经解决了按下power键灭屏与亮屏了！

（二）、但是客户的还需要触摸屏幕来唤醒！

因为板子实际上是并没有休眠的，所以此时触摸屏幕，并没有把背光点亮

解决思路是，在PhoneWindowManager 中，注册全局的触摸事件，监听ACTION_DOWN事件来点亮背光

1、在PhoneWindowManager 类中新增以下代码：【最后面】

// 2025/9/10 17:22 wenyuanbo add Open Backlight

private WindowManagerPolicy.PointerEventListener mPointerEventListener = new WindowManagerPolicy.PointerEventListener() {

@Override

public void onPointerEvent(MotionEvent motionEvent) {

if(motionEvent.getAction() == MotionEvent.ACTION_DOWN){

brightScreen();

}

};

2、修改PhoneWindowManager init 初始化方法

增加全局事件的注册

/** {@inheritDoc} */

@Override
public void init(Context context, WindowManagerFuncs windowManagerFuncs) {
mContext = context;
mWindowManagerFuncs = windowManagerFuncs;

// 2025/9/10 17:24 wenyuanbo add Open Backlight
mWindowManagerFuncs.registerPointerEventListener(mPointerEventListener, DEFAULT_DISPLAY);

mWindowManagerInternal = LocalServices.getService(WindowManagerInternal.class);

mActivityManagerInternal = LocalServices.getService(ActivityManagerInternal.class);

mActivityTaskManagerInternal = LocalServices.getService(ActivityTaskManagerInternal.class);

mInputManagerInternal = LocalServices.getService(InputManagerInternal.class);

mDreamManagerInternal = LocalServices.getService(DreamManagerInternal.class);

mPowerManagerInternal = LocalServices.getService(PowerManagerInternal.class);

mAppOpsManager = mContext.getSystemService(AppOpsManager.class);

mDisplayManager = mContext.getSystemService(DisplayManager.class);

mDisplayManagerInternal = LocalServices.getService(DisplayManagerInternal.class);

mPackageManager = mContext.getPackageManager();

mHasFeatureWatch = mPackageManager.hasSystemFeature(FEATURE_WATCH);

mHasFeatureLeanback = mPackageManager.hasSystemFeature(FEATURE_LEANBACK);

mHasFeatureAuto = mPackageManager.hasSystemFeature(FEATURE_AUTOMOTIVE);

mHasFeatureHdmiCec = mPackageManager.hasSystemFeature(FEATURE_HDMI_CEC);

mAccessibilityShortcutController =

new AccessibilityShortcutController(mContext, new Handler(), mCurrentUserId);

mLockPatternUtils = new LockPatternUtils(mContext);

mLogger = new MetricsLogger();

此时已经解决了触摸屏幕时，点亮屏幕的逻辑了。
