一、跳過頁面

private?SharedPreferences tiaozhuan；

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

//獲取isCheck的值，默認值是false

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

if(isCheck){? //如果isCheck = true第二次運行 直接跳過本頁面

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

????????startActivity(intent);

????????finish();

}

//把數(shù)據(jù)存儲進入sp

SharedPreferences.Editor edit = tiaozhuan.edit();

//存儲isCheck的值為true，為了跳過本頁面

edit.putBoolean("isCheck",true);

edit.commit();

二、自動登錄

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));

? ? ????}

});
