Android 隱藏Fragment

 1.隱藏Fragment

  FragmentManager fManager = getFragmentManager();
                    fManager.beginTransaction()
                            .setCustomAnimations(android.R.animator.fade_in,
                                    android.R.animator.fade_out)
                            .show(yourFragmentName).commit();

　　

 fManager.beginTransaction().remove(mMangerFragment);

　　

2.查看是否鎖屏

KeyguardManager km = (KeyguardManager) getSystemService(Context.KEYGUARD_SERVICE);
boolean locked = km.inKeyguardRestrictedInputMode();
