[Android流水化开发]工序3：如何增加点击事件，将各个页面连接在一起？

步骤

1. 在xml中对需要操作的组件添加id标识。常见标识如下：

• 输入组件，如input_phone
• 按钮组件，如btn_login（工序3只处理这一类组件）
• 信息组件，如show_title
• 容器组件，如contain_title

2. 透过ButterKnife Zelezny将 id 映射为 java 组件、将btn映射为点击方法。
   

   

3. 用butterfork代替butterknife。

• 用butterfork.Bind; 替换 butterknife.Bind
• 用butterfork.OnClick 替换 butterknife.OnClick
• 用B.id.替换R.id.
• 删除ButterKnife的相关代码。如：ButterKnife.bind(this, rootView);、ButterKnife.unbind(this);。

4. 添加按钮组件的点击事件。

@OnClick(B.id.btn_forget_pass)
public void forgetPass(){
        DevUtil.showInfo(getActivity(), "跳转忘记密码页面");
}
@OnClick(B.id.btn_login)
public void login(){
        DevUtil.showInfo(getActivity(), "登录");
}
@OnClick(B.id.btn_register)
public void register(){
        DevUtil.showInfo(getActivity(), "跳转注册页面");
}

5. 添加页面跳转代码

@OnClick(B.id.btn_login)
public void login(){
        DevUtil.showInfo(getActivity(), "模拟登录");
        IntentUtil.gotoActivity(getActivity(), MainActivity.class);
}
@OnClick(B.id.btn_register)
public void register(){
        IntentUtil.gotoActivity(getActivity(), RegisterActivity.class);
}

常用代码片段

一、启动页LaunchFragment

public class LaunchFragment extends BaseFragment {

    private long mLaunchViewDisplayTimeLength = 1000L; //启动页显示的时间
    @Override
    public int getLayoutId() {
        return R.layout.fragment_launch;
    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        View rootView = super.onCreateView(inflater, container, savedInstanceState);

        configLaunchView();
        return rootView;
    }
    /**
     * 配置启动界面
     */
    public void configLaunchView() {


        SimpleSafeTask waitLaunchViewDismissedTask = new SimpleSafeTask(
                getActivity()) {

            @Override
            protected Void doInBackgroundSafely() throws Exception {
                Thread.sleep(mLaunchViewDisplayTimeLength);
                return null;
            }

            @Override
            protected void onPostExecuteSafely(Void resultInfo, Exception e) {
                super.onPostExecuteSafely(resultInfo, e);
                if(DataManager.isLogined()){
                    IntentUtil.gotoActivity(getActivity(), MainActivity.class);
                }
                else{
                    IntentUtil.gotoActivity(getActivity(), LoginActivity.class);
                }
                getActivity().finish();
            }

        };
        waitLaunchViewDismissedTask.execute();
    }
}

二、列表数据对应的页面

public class NearbyFragment extends AbsListViewNetFragment {
    @Bind(B.id.tv_title)
    TextView mTvTitle;
    @Bind(B.id.net_list)
    GridView mGvNearby;

    @Override
    public int getLayoutId() {
        return R.layout.fragment_nearby;
    }

    @Override
    protected ListNetResultInfo onDoInBackgroundSafely(int i, int i1) {
        return TestModel.getListNetResultInfo(100);
    }

    @Override
    public int getItemTextViewResourceId() {
        return R.id.tv_test;
    }

    @Override
    public int getItemLayoutId() {
        return R.layout.item_nearby_detail;
    }

    @Override
    public View bindView(int i, View view, ViewGroup viewGroup) {
        return view;
    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        View rootView = super.onCreateView(inflater, container, savedInstanceState);
        mGvNearby.setOnItemClickListener(new AdapterView.OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView adapterView, View view, int i, long l) {
                // TODO: 16/8/5 跳转详情列表 
                DevUtil.showInfo(getActivity(), "item 点击");
            }
        });
        return rootView;
    }


    @OnClick(B.id.btn_goback)
    public void exit() {
        super.exit();
    }
}
