Question

我试图在屏幕关闭的同时禁用锁定屏幕，但屏幕关闭后再次锁定。

我使用下面的代码来禁用锁定屏幕：

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
    activity.getWindow().addFlags(WindowManager.LayoutParams.FLAG_DISMISS_KEYGUARD);
} else {
    KeyguardManager km = (KeyguardManager) activity.getSystemService(KEYGUARD_SERVICE);
    kl = km.newKeyguardLock("name");
    kl.disableKeyguard();
}

启用锁定屏幕：

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
    activity.getWindow().clearFlags(WindowManager.LayoutParams.FLAG_DISMISS_KEYGUARD);
} else {
    KeyguardManager km = (KeyguardManager) activity.getSystemService(KEYGUARD_SERVICE);
    kl = km.newKeyguardLock("name");
    kl.reenableKeyguard();
}

Answer 1

在活动的OnCreate中尝试此操作。

console.log((<HTMLInputElement>document.getElementById('char').textContent))

Answer 2

请在android.manifest.xml

中提供以下权限
<uses-permission android:name="android.permission.DISABLE_KEYGUARD"/>
