问题描述
我正在尝试使用Roman Nurik的库( https://plus.google.com/113735310430199015092/posts/6cVymZvn3f4 ).
I am trying to make a wizard using Roman Nurik's library (https://plus.google.com/113735310430199015092/posts/6cVymZvn3f4).
我无法访问审阅片段"中收集的数据.我在ReviewFragment中公开了mCurrentReviewItems,然后像这样尝试了
I am having trouble accessing the collected data from the Review Fragment.I made mCurrentReviewItems public in ReviewFragment and then I tried it like this
mNextButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
if (mPager.getCurrentItem() == mCurrentPageSequence.size()) {
ReviewFragment reviewFragment = (ReviewFragment) mPagerAdapter.getItem(mPager.getCurrentItem());
for (ReviewItem item : reviewFragment.mCurrentReviewItems)
Log.d(MainActivity.TAG, "Item: " + item.getDisplayValue());
}
} else {
if (mEditingAfterReview) {
mPager.setCurrentItem(mPagerAdapter.getCount() - 1);
} else {
mPager.setCurrentItem(mPager.getCurrentItem() + 1);
}
}
}
});
但是它始终为空.
推荐答案
内部 if(mPager.getCurrentItem()== mCurrentPageSequence.size()){}
对于单页变量:
String data = mWizardModel.findByKey("Sandwich:Bread").getData().getString(Page.SIMPLE_DATA_KEY);
对于自定义页面:
String data =
mWizardModel.findByKey(THE_KEY).getData().getString(CustomerInfoPage.YOUR_DATA_KEY);
如果要将数据分配回向导,请将其放在FragmentActivity中onCreate的末尾:
If you want to assign the data back to the wizard, put this at the end of onCreate in FragmentActivity:
Bundle data = new Bundle();
if (!TextUtils.isEmpty(DATA_STRING)) {
data.putString(Page.SIMPLE_DATA_KEY, DATA_STRING);
mWizardModel.findByKey("Sandwich:Bread"").resetData(data);
}
键三明治:面包"来自示例,请更改适合您的内容.千万不要尝试多合一,我认为它或多或少都是一样的.
The key "Sandwich:Bread" is from the example, change whatever suit you. Never try the multi one, I think it is more or less the same.
