去掉标题栏和系统栏代码实现以及动态设置密码

//Remove title bar?
this.requestWindowFeature(Window.FEATURE_NO_TITLE);?

//Remove notification bar?
this.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);?

当然还有xml实现那就比较简单了 直接用主题就好了

mEdit.setTransformationMethod(PasswordTransformationMethod.getInstance());?
