android fragment setuservisiblehint,在Fragment中的onCreateView之前调用的setUserVisibleHint

// create boolean for fetching data

private boolean isViewShown = false;

@Override

public void setUserVisibleHint(boolean isVisibleToUser) {

super.setUserVisibleHint(isVisibleToUser);

if (getView() != null) {

isViewShown = true;

// fetchdata() contains logic to show data when page is selected mostly asynctask to fill the data

fetchData();

} else {

isViewShown = false;

}

}

使用isViewShown实例变量来决定要在中onCreateView()还是在中获取数据setUserVisibleHint()。

下面的代码包含以下逻辑onCreateView()：

@Override

public View onCreateView(LayoutInflater inflater, ViewGroup container,

Bundle savedInstanceState) {

View view = inflater.inflate(R.layout.main_layout, container, false);

// view initialization steps.......

if (!isViewShown) {

fetchData();

}

// do other stuff

}

此代码将解决您的问题。因为它解决了我的问题。:)

这个技巧将获取数据，onCreateView()以便直接从一页跳转到另一页，而当您滑动视图时，它将从setUserVisibleHint()方法中获取数据。:)
