本文介绍了一个基于Android平台的应用架构设计，包括使用Butterknife进行视图绑定、通过Retrofit实现网络请求、采用Dagger进行依赖注入等关键技术。此外，还详细展示了BaseActivity和BaseFragment的实现方式，并给出了MainActivity的具体实例。

第一步先是构建BaseActivity

public interface IBase {
    int getContentLayout();

    void inject();

    void initView(View view);
}

public interface BaseContract {
    //抽取所有Presenter共性，比如绑定，解绑
    interface BasePresenter<T extends BaseView> {
        void attchView(T view);

        void detachView();
    }

    //抽取所有View的共性，比如显示进度条和关闭进度
    interface BaseView {
        void showLoading();

        void dismissLoading();
    }
}

public class BasePresenter<T extends BaseContract.BaseView> implements BaseContract.BasePresenter<T> {
    protected T mView;

    @Override
    public void attchView(T view) {
        this.mView = view;
    }

    @Override
    public void detachView() {
        if (mView != null) {
            mView = null;
        }
    }
}

条件已经备好，接下来便是BaseActivity

public abstract class BaseActicity<T extends BaseContract.BasePresenter> extends AppCompatActivity
        implements IBase, BaseContract.BaseView {
    @Inject
    protected T mPresenter;

    @Override
    protected void onCreate(@Nullable Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(getContentLayout());
        inject();
        //绑定
        if (mPresenter != null) {
            mPresenter.attchView(this);
        }
    }

    @Override
    public void initView(View view) {

    }

    @Override
    protected void onDestroy() {
        super.onDestroy();
        //解绑
        if (mPresenter != null) {
            mPresenter.detachView();
        }
    }

    @Override
    public void showLoading() {

    }

    @Override
    public void dismissLoading() {

    }
}

MianActivity

public class MainActivity extends BaseActicity {

    private BottomTabBar bottom_tab_bar;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        initView();
        bottom_tab_bar.init(getSupportFragmentManager())
                //   .setImgSize(50,50)
                .setFontSize(12)
                .setTabPadding(4, 6, 10)
                .setChangeColor(Color.RED, Color.DKGRAY)
                .addTabItem("首页", null, OneFragment.class)
                .addTabItem("分类", null, TwoFragment.class)
                .addTabItem("发现", null, ThreeFragment.class)
                .addTabItem("购物车", null, FourFragment.class)
                .addTabItem("我的", null, FiveFragment.class)
                .isShowDivider(false)
                .setOnTabChangeListener(new BottomTabBar.OnTabChangeListener() {
                    @Override
                    public void onTabChange(int position, String name) {

                    }
                });
    }

    @Override
    public int getContentLayout() {
        return R.layout.activity_main;
    }

    @Override
    public void inject() {

    }

    private void initView() {
        bottom_tab_bar = (BottomTabBar) findViewById(R.id.bottom_tab_bar);
    }
}

BaseFragment

public abstract class BaseFragment<T extends BaseContract.BasePresenter> extends Fragment implements IBase,
        BaseContract.BaseView {
    @Inject
    protected T mPresenter;
    private Unbinder bind;

    @Override
    public void onCreate(@Nullable Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        inject();
        if (mPresenter != null) {
            mPresenter.attchView(this);
        }
    }

    @Override
    public void onDestroy() {
        super.onDestroy();
        if (mPresenter != null) {
            mPresenter.detachView();
        }
        if (bind != null) {
            bind.unbind();
        }
    }

    @Nullable
    @Override
    public View onCreateView(@NonNull LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle
            savedInstanceState) {
        View view = inflater.inflate(getContentLayout(), null);
        bind = ButterKnife.bind(getActivity(), view);
        initView(view);
        return view;
    }
    
    @Override
    public void showLoading() {

    }

    @Override
    public void dismissLoading() {

    }
}

public class TwoFragment extends BaseFragment {
    
    @Override
    public int getContentLayout() {
        return R.layout.fragment2;
    }

    @Override
    public void inject() {

    }

    @Override
    public void initView(View view) {

    }
}
