BaseFragment 基于ViewBinding和懒加载on

public abstract class BaseFragment<T extends ViewBinding> extends Fragment {
    public static final String TAG = "BaseFragment";
    protected FragmentActivity mActivity;
    protected T binding; // 泛型绑定类
    private boolean isLoaded = false;

    @Override
    public void onAttach(@NotNull Context context) {
        super.onAttach(context);
        mActivity = getActivity();
    }

    @Nullable
    @Override
    public View onCreateView(@NotNull LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
        binding = createViewBinding(inflater, container); // 创建绑定类实例
        initData(getArguments());
        initView();
        return binding.getRoot(); // 返回根视图
    }

    // 创建视图绑定的抽象方法
    protected abstract T createViewBinding(LayoutInflater inflater, ViewGroup container);

    protected void initData(Bundle arguments) {
    }

    protected abstract void initView();

    @Override
    public void onResume() {
        super.onResume();
        Log.d(TAG, "onResume");
        if (!isLoaded) {
            onLazyLoad();
            Log.d(TAG, this + "lazyInit:!!!!!!!");
            isLoaded = true;
        }
    }

    protected void onLazyLoad() {

    }

    @Override
    public void onDestroy() {
        super.onDestroy();
        isLoaded = false;
    }

}

使用方式

build.gradle文件添加支持dataBinding

   dataBinding {
        enabled = true
    }

重写 createViewBinding（）绑定布局文件.xml

public class VojsLiveCoverFragment extends BaseFragment<VojsliveCoverFragmentBinding> {
    public static final String TAG = "VojsLiveCoverFragment";

    @Override
    protected VojsliveCoverFragmentBinding createViewBinding(LayoutInflater inflater, ViewGroup container) {
        return VojsliveCoverFragmentBinding.inflate(inflater, container, false);
    }

    public static VojsLiveCoverFragment newInstance(VojsLJBean vojsLJBean) {
        VojsLiveCoverFragment fragment = new VojsLiveCoverFragment();
        Bundle args = new Bundle();
        args.putSerializable(VOJS_LJ_BEAN, vojsLJBean);
        fragment.setArguments(args);
        return fragment;
    }

    @Override
    protected void initView() {
         Glide.with(getContext()).load("URL").into(binding.blurCoverImageView);
    }

}
