【重大bug】viewpager使用的时候加载数据应该在setOnPageChangeListener里加载

 1 mPagerTab.setOnPageChangeListener(new OnPageChangeListener() {
 2 
 3             @Override
 4             public void onPageSelected(int position) {
 5                 BaseFragment fragment = FragmentFactory
 6                         .createFragment(position);
 7                 // 开始加载数据
 8                 fragment.loadData();
 9             }
10 
11             @Override
12             public void onPageScrolled(int position, float positionOffset,
13                     int positionOffsetPixels) {
14             }
15 
16             @Override
17             public void onPageScrollStateChanged(int state) {
18             }
19         });

    @Nullable
    @Override
    public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
//        TextView view = new TextView(UIUtils.getContext());
//        view.setText(this.getClass().getSimpleName());
//        return view;

        mLoadingPage = new LoadingPage(UIUtils.getContext()) {
            @Override
            public StateResult onLoadData() {
                return BaseFragment.this.onLoadData();
            }

            @Override
            public View onCreateSuccessView() {
                return BaseFragment.this.onCreateSuccessView();
            }
        };
        mLoadingPage.loadData();//开始加载数据
        return mLoadingPage;
    }

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        mLoadingPage = new LoadingPage(this) {

            @Override
            public ResultState onLoad() {
                return HomeDetailActivity.this.onLoad();
            }

            @Override
            public View onCreateSuccessView() {
                return HomeDetailActivity.this.onCreateSuccessView();
            }
        };

        // setContentView(R.layout.activity_main);
        setContentView(mLoadingPage);// 直接将一个view对象设置给activity

        // 获取从HomeFragment传递过来的包名
        packageName = getIntent().getStringExtra("packageName");

        // 开始加载网络数据
        mLoadingPage.loadData();

        initActionbar();
    }
