Android 如何在onSaveInstanceState一次保存所有布尔人？

调用onSaveInstanceState时，是否有方法捕获应用程序的快照

否则，我必须保存每个布尔值并跟踪它们，尽量不要忘记某些内容，如：

@Override
    protected void onSaveInstanceState(Bundle outState) {
        super.onSaveInstanceState(outState);
        if (userAvatar != null) {
            outState.putString("userAvatar", userAvatar.toString());
            avatarAlreadyProvided = true;
        }
        if (sexIsOK) {
            outState.putBoolean("sexIsOK", true);
        }
        if (passwordIsOk) {
            outState.putBoolean("passwordIsOk", true);          
        }
        if (passwordAgainIsOk) {
            outState.putBoolean("passwordAgainIsOk", true);         
        }
        if (passwordsMatch) {
            outState.putBoolean("passwordsMatch", true);                
        }
        if (userHasProvidedOwnPhoto != false) {
            outState.putBoolean("userHasProvidedOwnPhoto", true);
            outState.putBoolean("avatarAlreadyProvided", true);
        }
        if (mImageBitmap != null) {
            outState.putParcelable("mImageBitmap", mImageBitmap);
            avatarAlreadyProvided = true;
        }
        if (usernameIsOk) {
            outState.putBoolean("usernameIsOk", true);          
        }
        if (allSignupFieldsProperlyFilled) {
            outState.putBoolean("allSignupFieldsProperlyFilled", true);         
        }
    }

    @Override
    protected void onRestoreInstanceState(Bundle outState) {
        super.onRestoreInstanceState(outState);
        userHasProvidedOwnPhoto = outState.getBoolean("userHasProvidedOwnPhoto");
        avatarAlreadyProvided = outState.getBoolean("avatarAlreadyProvided");
        mImageBitmap = outState.getParcelable("mImageBitmap");
        userAvatar = outState.getString("userAvatar");
        iUserAvatar.setImageBitmap(mImageBitmap);
        allSignupFieldsProperlyFilled = outState.getBoolean("allSignupFieldsProperlyFilled");
        usernameIsOk = outState.getBoolean("usernameIsOk");
        passwordsMatch = outState.getBoolean("passwordsMatch");
        passwordAgainIsOk = outState.getBoolean("passwordAgainIsOk");
        passwordIsOk = outState.getBoolean("passwordIsOk");
        sexIsOK = outState.getBoolean("sexIsOK");


    }

我总是忘记一些事情，然后把它搞砸。必须有其他方法……

将变量包装到Java类中并使用序列化。您可以使用Gson进行Json序列化

好吧，再一次，我必须得到我所有的变量？你能给我举个例子吗？即使Java对象序列化中有100个变量，也会将保存和加载减少到几行。首先向项目中添加一个新类，并将所有变量移动到其中。然后看看我链接到的另一个答案。那么我在onSaveInstanceState中做什么呢？我序列化变量对象？
