在inKeyguardRestrictedInputMode()中返回失败结果

Question

我有一个功能来确定手机屏幕的四种状态:屏幕打开,屏幕关闭,屏幕打开锁定,屏幕打开无锁定.我的功能是

private KeyguardManager keyguardManager;
public String getScreenStatus()
{
    String sreen_State="unknown";
    keyguardManager = (KeyguardManager) getSystemService(KEYGUARD_SERVICE);
    PowerManager pm = (PowerManager) getApplicationContext().getSystemService(Context.POWER_SERVICE);
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT_WATCH) {
        if (pm.isInteractive()) {
            sreen_State="screen_on";
            if(!keyguardManager.inKeyguardRestrictedInputMode()) {
                sreen_State="screen_on_no_lock_screen";

            }else{
                Log.i(TAG, "screen_on_lock_screen");
                sreen_State="screen_on_lock_screen";
            }
        }
        else {
            sreen_State="screen_off";
        }
    }
    else if(Build.VERSION.SDK_INT < Build.VERSION_CODES.KITKAT_WATCH){
        if(pm.isScreenOn()){
            sreen_State="screen_on";
            if(!keyguardManager.inKeyguardRestrictedInputMode()) {
                Log.i(TAG, "screen_on_no_lock_screen");
                sreen_State="screen_on_no_lock_screen";

            }else{
                Log.i(TAG, "screen_on_lock_screen");
                sreen_State="screen_on_lock_screen";
            }

        }
        else {
            mIsScreenOn=false;
            sreen_State="screen_off";
        }
    }
    return sreen_State;
}

上述功能返回屏幕的校正状态.但是,当我再添加一个代码时,它有错误,如下所示:

 KeyguardManager.KeyguardLock
 kl = keyguardManager.newKeyguardLock("MyKeyguardLock");
 if(index.equals("1"))
        kl.disableKeyguard();
  else if(indexequals("2"))
        kl.reenableKeyguard();
  getScreenStatus();

按下按钮可以改变索引.现在,屏幕状态出现了错误.它总是返回screen_on_lock_screen,虽然屏幕在screen_on_no_lock_screen.我怎么能解决我的问题？

usingKeyguardManager.NewKeyguardLock自 API Level 13 起已被弃用。您是否尝试过使用WindowManager.LayoutParamsFLAG_DISMISS_KEYGUARD和FLAG_SHOW_WHEN_LOCKEDWindowManager.LayoutParams？

该类在 API 级别 13 中已弃用。请改用 FLAG_DISMISS_KEYGUARD 和/或 FLAG_SHOW_WHEN_LOCKED ；这允许您在应用程序移入和移出前台时无缝隐藏键盘保护，并且不需要请求任何特殊权限。> newKeyguardLock(String) 返回的句柄允许您禁用/ >重新启用键盘保护。
