如何以编程方式获取和设置"Super Fast Charging"设置？

Question

举个例子，我可以得到这样的显示超时设置：

int timeout=Settings.System.getInt(getContentResolver((，Settings.System.SCREEN_OFF_timeout(；

我可以这样设置显示超时设置：

Settings.System.putInt(getContentResolver((，Settings.System.Screeen_OFF_TIMEOUT，10000(；

如何以编程方式获取和设置快速充电和超级快速充电设置

编辑：感谢Veniamin帮助我获得正确的变量名，以下是对我有效的方法：

try {
int isSuperFastChargingEnabled = Settings.System.getInt(getContentResolver(), "super_fast_charging");
if ( isSuperFastChargingEnabled == 0) {
Settings.System.putInt(getContentResolver(), "super_fast_charging", 1);
Settings.System.putInt(getContentResolver(), "adaptive_fast_charging", 1);
Toast.makeText(this, "Fast charge is set to 1",Toast.LENGTH_LONG).show();
} else if ( isSuperFastChargingEnabled == 1) {
Settings.System.putInt(getContentResolver(), "super_fast_charging", 0);
Settings.System.putInt(getContentResolver(), "adaptive_fast_charging", 0);
Toast.makeText(this, "Fast charge is set to 0",Toast.LENGTH_LONG).show();
}
} catch (Settings.SettingNotFoundException e) {
Toast.makeText(this,"Failed to get fast charge setting",Toast.LENGTH_LONG).show();
}

您可以在Device CareSamsung系统应用程序中读取和更新这些设置，所以我对其进行了逆向工程。

以下是您如何在应用程序中阅读快速充电、超级快速充电和无线快速充电置：

val isSuperFastChargingEnabled = Settings.System.getInt(context.contentResolver, "super_fast_charging", 0) == 1
val isFastChargingEnabled = Settings.System.getInt(context.contentResolver, "adaptive_fast_charging", 0) == 1
val isFastWirelessChargingEnabled = Settings.System.getInt(context.contentResolver, "wireless_fast_charging", 0) == 1

不幸的是，要以编程方式更新这些设置，您需要android.permission.WRITE_settings权限仅授予系统应用程序。

因此，如果你没有开发系统应用程序，启用这些设置的唯一方法就是要求用户手动启用它们。为了简化工作流程，您可以将用户直接路由到系统Fast Charging Settings活动，如下所示：

val intent = Intent()
intent.component = ComponentName(
"com.samsung.android.lool",
"com.samsung.android.sm.battery.ui.BatteryAdvancedMenuActivity"
)
// Activity class name may be updated in future versions, so
// the safest way to handle Activity class name updates is to wrap this
// call in the try/catch and add a custom error handling if the activity wasn't found.
try {
startActivity(intent)
} catch (e: Exception) {
// Custom error handling
}

由于这些设置是特定于供应商的，因此建议在读取它们之前检查供应商id。

我测试了它，并确认它适用于三星Galaxy S20(SM-G980F/DS(；安卓12；一个UI 4.1。
