import screenLock from '@ohos.screenLock';

screenLock.isScreenLocked(deprecated)

isScreenLocked(callback: AsyncCallback<boolean>): void

判斷屏幕是否鎖屏。使用callback異步回調(diào)。

系統(tǒng)能力： SystemCapability.MiscServices.ScreenLock

參數(shù)：

示例：

screenLock.isScreenLocked((err, data)=>{      
    if (err) {
        console.error(`Failed to obtain whether the screen is locked, because: ${err.message}`);
        return;    
    }
    console.info(`Obtain whether the screen is locked successfully. result: ${data}`);
});

screenLock.isScreenLocked(deprecated)

isScreenLocked(): Promise<boolean>

判斷屏幕是否鎖屏。使用Promise異步回調(diào)。

系統(tǒng)能力： SystemCapability.MiscServices.ScreenLock

返回值：

示例：

screenLock.isScreenLocked().then((data) => {
    console.info(`Obtain whether the screen is locked successfully. result: ${data}`);
}).catch((err) => {
    console.error(`Failed to obtain whether the screen is locked, because: ${err.message}`);
});

screenLock.isSecureMode(deprecated)

isSecureMode(callback: AsyncCallback<boolean>): void

判斷當前設(shè)備的屏幕鎖定是否安全（安全屏幕鎖定意味著解鎖屏幕需要密碼、圖案或其他用戶身份識別）。使用callback異步回調(diào)。

系統(tǒng)能力： SystemCapability.MiscServices.ScreenLock

參數(shù)：

示例：

screenLock.isSecureMode((err, data)=>{
    if (err) {
        console.error(`Failed to obtain whether the device is in secure mode, because: ${err.message}`);
        return;
    }
    console.info(`Obtain whether the device is in secure mode successfully. result: ${data}`);
});

screenLock.isSecureMode(deprecated)

isSecureMode(): Promise<boolean>

判斷當前設(shè)備的屏幕鎖定是否安全（安全屏幕鎖定意味著解鎖屏幕需要密碼、圖案或其他用戶身份識別）。使用Promise異步回調(diào)。

系統(tǒng)能力： SystemCapability.MiscServices.ScreenLock

返回值：

示例：

screenLock.isSecureMode().then((data) => {
    console.info(`Obtain whether the device is in secure mode successfully. result: ${data}`);
}).catch((err) => {
    console.error(`Failed to obtain whether the device is in secure mode, because: ${err.message}`);
});

screenLock.unlockScreen(deprecated)

unlockScreen(callback: AsyncCallback<void>): void

解鎖屏幕。使用callback異步回調(diào)。

系統(tǒng)能力： SystemCapability.MiscServices.ScreenLock

參數(shù)：

示例：

screenLock.unlockScreen((err) => {      
    if (err) {
        console.error(`Failed to unlock the screen, Code: ${err.code}, message: ${err.message}`);
        return;    
    }
    console.info('unlock the screen successfully.');
});

screenLock.unlockScreen(deprecated)

unlockScreen(): Promise<void>

解鎖屏幕。使用Promise異步回調(diào)。

系統(tǒng)能力： SystemCapability.MiscServices.ScreenLock

返回值：

示例：

screenLock.unlockScreen().then(() => {
    console.info('unlock the screen successfully.');
}).catch((err) => {
    console.error(`Failed to unlock the screen, Code: ${err.code}, message: ${err.message}`);
});
