问题 I have write below code to toggle the KeyGaurd of my android phone using a toggle button. but I am facing an strange behavior. it disables the keygaurd successfully but. not re-enabling. btnToggleLock.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { if (btnToggleLock.isChecked()) { toast.cancel(); toast.setText("Unlocked"); toast.show(); Log.i("Unlocked", "If"); KeyguardManager myKeyGuard = (KeyguardManager) getSystemService(Context.KEYGUARD_SERVICE);

问题 I have my main activity A and when the user presses a button i open another activity B. But when this happens B doesn't just appear on top of A: A disappears secure keyguard shows up B appears And when i get rid of B the same thing happens. This is annoying because there's a lot of flickering with no real purpose on the screen. Is there any way to achieve direct transition from A to B while keyguard is active without merging the 2 activities into 1? Here is what i'm doing in onCreate for both

问题 How can I disable the keyguard when a broadcast receiver is activated by screen_on, so that when it occurs the user sees an activity that I have started behind it?

KeyguardManager myKeyGuard = (KeyguardManager)getSystemService(Context.KEYGUARD_SERVICE); myLock = myKeyGuard.newKeyguardLock(); myLock.disableKeyguard(); It doesn't seem to be working though as it is.
