如何只显示一次提交屏幕？

Question

I am using this code in main activity for display Registration detail page only one time.

setContentView(R.layout.register_data);
startActivity(new Intent(RegisterDetail.this, MainActivity.class));

getSharedPreferences("PREFERENCE", MODE_PRIVATE)
boolean isFirstRun = getSharedPreferences("PREFERENCE", MODE_PRIVATE).getBoolean("isFirstRun", true);
if (isFirstRun){
    .edit()
    .putBoolean("isFirstRun", false)
    .apply();
}

but I have problem. If some one close app without submit details and reopen app, that page doesn't display. I want to display register_data page until user doesn't submit details.

共享的首选项在活动之间共享-为什么不仅在收到确认输入了注册详细信息（并正确保存在服务器端）的确认后才写首选项？

Change the MODE_PRIVATE to Context.MODE_PRIVATE while creating the file and one problem is that you are calling startActivity(...) before checking if the PREFERENCE.xml file contains true or false. So first check whats is present inside the file and that accordingly take the action
