When an android alarm is triggered, press the power key to lock the screen. Two lockscreen sounds will be played.
Two locks are triggered because Keyguard is locked when the screen is hidden, and then keyguard is automatically unlocked because FLAG_DISMISS_KEYGUARD windowsParam is set in alarm activity, this is the design of Google AOSP, and there will be two sides to the phone of Google AOSP, so the suggestions do not need to be modified.
 
Modify:
Alps \ frameworks \ base \ packages \ Keyguard \ src \ com \ android \ keyguard \ KeyguardViewMediator. java
# About 1384 rows:
 
MSuppressNextLockSound = false;
 
To:
If (authenticated ){
MSuppressNextLockSound = false;
} Else {
MSuppressNextLockSound = true;
}
 
It is also a non-user manual unlock situation, Suppress next Lock sound, no unlock sound.


Do not display the alarm time on the screen lock of your Android phone

I mean, probably, because there are many versions of Android, and it is impossible for every version to be the same. In general, this process should be the process. Choose system Settings> interface> screen lock shortcut.
After entering, move to each shortcut and set it to null.
In fact, you can change the unlock mode without sliding the unlock method. For example, you can unlock the pattern, pin, and password. In this way, the screen lock page will not appear.

As for what you said, the clock and alarm clock may not be fully achieved. You can set them on the screen lock page with a clock widget. after entering the widget, you can choose whether to display the digital clock or analog clock, whether to display the alarm clock, but it may not work at all. I use the CM10 system. You may be able to download a third-party lock theme to solve this problem.

Android cannot lock the screen when talking, nor press the power key. How can this problem be solved ??

This is not the case. If the system presses the power key, it means that the device is sleep. How can I sleep during a call. You can write an application in this way. The interface is exactly the same as the screen lock. Haha. Malicious customers
