SCREEN_OFF_TIMEOUT, FALLBACK_SCREEN_TIMEOUT_VALUE);//获取到设置的屏幕超时休眠时间 timeoutListPreference.setValue(String.valueOf(currentTimeout)); final DevicePolicyManager dpm = (DevicePolicyManager) mContext.getSystemService(Context.DEVICE_POLICY_SERVICE); if (dpm != null) { final RestrictedLock...
devicePolicyManager.setMaximumTimeToLock(componentName,timeoutMillis); 1. 上述代码中,componentName是组件名称,可以通过以下代码获取: componentName=newComponentName(this,DeviceAdminReceiver.class); 1. timeoutMillis是以毫秒为单位的超时时间。例如,要设置屏幕关闭超时时间为5分钟,我们可以使用以下代码: longtimeoutM...
代码很简单,如下: privatevoidchangeScreenOffTime(){ Log.i("xxxxx","changeScreenOffTime: "+System.currentTimeMillis()); Settings.System.putInt(getContentResolver(),Settings.System.SCREEN_OFF_TIMEOUT,1000*60*60*24); } 获取屏幕超时时间: try{intanInt=Settings.System.getInt(getContentResolver(), ...
在这一步中,我们使用了Settings类中的putInt方法来设置锁屏超时时间。我们通过指定SCREEN_OFF_TIMEOUT键来设置超时时间,单位为毫秒。 Settings.System.putInt(getContentResolver(),Settings.System.SCREEN_OFF_TIMEOUT,5*60*1000); 1. 步骤5:保存设置 最后,我们使用了广播来发送一个关闭系统对话框的Intent,以保存设...

方法一、调整代码：Settings.System.putInt(getContentResolver(),android.provider.Settings.System.SCREEN_OFF_TIMEOUT,-1);权限：<uses-permission android:name="android.permission.WRITE_SETTINGS" /> 方法二、调整数据库：android的这些设置都是存放在sql数据库里的，也就是说可以直接通过修改数据库来...
