一、跳过页面

private SharedPreferences tiaozhuan；

tiaozhuan = getSharedPreferences("tiaozhuan", Context.MODE_PRIVATE);

//获取isCheck的值，默认值是false

boolean isCheck = tiaozhuan.getBoolean("isCheck", false);

if(isCheck){  //如果isCheck = true第二次运行 直接跳过本页面

        Intent intent = new Intent(this,Main2Activity.class);

        startActivity(intent);

        finish();

}

//把数据存储进入sp

SharedPreferences.Editor edit = tiaozhuan.edit();

//存储isCheck的值为true，为了跳过本页面

edit.putBoolean("isCheck",true);

edit.commit();

二、自动登录

final SharedPreferences aa = getActivity().getSharedPreferences("aa", Context.MODE_PRIVATE);

boolean idcheck = aa.getBoolean("idcheck", false);

if(idcheck){

        startActivity(new Intent(getActivity(),MainActivity.class));

}

login.setOnClickListener(new View.OnClickListener() {

        @Override

        public void onClick(View v) {

                SharedPreferences.Editor edit =aa.edit();

                edit.putBoolean("idcheck",mem.isChecked());

                edit.commit();

                startActivity(new Intent(getActivity(),MainActivity.class));

        }

});
