判断屏幕锁状态的方式

判断屏幕锁状态的方式

a. 接收广播判断屏幕的三种状态（ON & OFF & TURN ON）

private final BroadcastReceiver mReceiver = new BroadcastReceiver() {
    @Override
    public void onReceive(Context context, Intent intent) {
        final String action = intent.getAction();
        if (Intent.ACTION_USER_PRESENT.equals(action)) {
           //解锁
            }
        }
    }
};

registerReceiver(mReceiver, new IntentFilter(Intent.ACTION_USER_PRESENT));

b. 通过KeyGuardManager判断屏幕状态

KeyguardManager keyguardManager =
                (KeyguardManager)getSystemService(Context.KEYGUARD_SERVICE);
boolean keyguard = keyguardManager.isKeyguardLocked() && 
                 keyguardManager.isKeyguardSecure();
