将锁屏设置为“无”。编程？ [英] Set lockscreen to "None" programmatically?
问题描述
我要求禁用锁定屏幕并将锁定屏幕类型设置为无。我的设备已植根（可以使用SU权限运行）+可以作为具有系统权限的系统应用程序运行（在/ system / app下）。
I have the requirement to disable the lock screen and set the lock screen type to "None". My device is rooted (can run with SU permission) + can run as a system application with system permissions (under /system/app).
我尝试过一些东西无效。
I have tried a few things to no avail.
尝试1
这似乎已被弃用，而不是工作。
This seems to be deprecated and not working.
KeyguardManager manager = (KeyguardManager) this.getSystemService(KEYGUARD_SERVICE);
KeyguardLock lock = manager.newKeyguardLock("abc");
lock.disableKeyguard();
尝试2
这也不起作用。
- 将系统分区挂载为可写
- 编辑
/data/data/com.android.providers.settings/databases/settings.db -
执行以下SQL。
- Mount system partition as writable
- Edit
/data/data/com.android.providers.settings/databases/settings.db Execute the following SQL.
INSERT OR REPLACE INTO系统（名称，值）VALUES（'lockscreen.disabled'，'1'）;
INSERT OR REPLACE INTO安全（名称，值）VALUES（'lockscreen.disabled'，'1'）;
尝试3
重新启动机器但仍然没有运气。
Rebooted the machine but still no luck.
android.provider.Settings.Secure.putLong(mContentResolver, Settings.Secure.LOCK_PATTERN_ENABLED, false);`
android.provider.Settings.Secure.putLong(mContentResolver, "lockscreen.password_type", DevicePolicyManager.PASSWORD_QUALITY_SOMETHING);`
android.provider.Settings.Secure.putLong(mContentResolver, "lockscreen.password_type_alternate", DevicePolicyManager.PASSWORD_QUALITY_UNSPECIFIED);
android.provider.Settings.Secure.putLong(mContentResolver, "lockscreen.disabled", true);
还有什么可以尝试吗？
请注意我不想仅在应用程序运行时禁用键盘锁。
推荐答案
你可以试试这个：
adb shell sqlite3 /data/system/locksettings.db "UPDATE locksettings SET value = '1' WHERE name = 'lockscreen.disabled'"
adb shell sqlite3 /data/system/locksettings.db "UPDATE locksettings SET value = '0' WHERE name = 'lockscreen.password_type'"
adb shell sqlite3 /data/system/locksettings.db "UPDATE locksettings SET value = '0' WHERE name = 'lockscreen.password_type_alternate'"
它适用于我的root用户Nexus 4.
It works on my rooted Nexus 4.
