使用Recyclerview嵌套实现购物车全选反选

在drawable创建selector改变CheckBox外形

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">

    <item android:drawable="@drawable/checkbox_round_0" android:state_checked="false"/>
    <item android:drawable="@drawable/checkbox_round_1" android:state_checked="true"/>

</selector>

style样式引用

<style name="main_check" parent="@style/Widget.AppCompat.CompoundButton.CheckBox">
    <item name="android:button">@drawable/checkbox_selector</item>
</style>

首先封装一个OKHTTPUtil网络请求工具类

public class OkHttpUtils {

    @SuppressLint("HandlerLeak")
    private Handler handler = new Handler() {
        @Override
        public void handleMessage(Message msg) {
            super.handleMessage(msg);
            switch (msg.what) {
                case 0:
                    String data = (String) msg.obj;
                    okHttpListener.response(data);
                    break;
                case 1:
                    String error = (String) msg.obj;
                    okHttpListener.failure(error);
                    break;
            }
        }
    };

    public OkHttpUtils get(String url) {
        OkHttpClient okHttpClient = new OkHttpClient();
        Request request = new Request.Builder()
                .url(url)
                .build();
        okHttpClient.newCall(request).enqueue(new Callback() {
            @Override
            public void onFailure(Call call, IOException e) {
                Message message = handler.obtainMessage();
                message.what = 1;
                message.obj = e.getMessage();
                handler.sendMessage(message);
            }

            @Override
            public void onResponse(Call call, Response response) throws IOException {
                Message message = handler.obtainMessage();
                message.what = 0;
                message.obj = response.body().string();
                handler.sendMessage(message);
            }
        });

        return this;
    }

    private OkHttpListener okHttpListener;

    public void setOkHttpListener(OkHttpListener okHttpListener) {
        this.okHttpListener = okHttpListener;
    }

    public interface OkHttpListener {
        void failure(String error);

        void response(String data);
    }

}

创建Listener文件

public interface ReItemListener {
    void onchekChange(List<MainDataBean.DataBean.ListBean> list, int i);
}

public interface ReListener {
    void checkChange();
}

MVP  view层接口

public interface IDelegate {
    void create(LayoutInflater inflater, ViewGroup viewGroup, Bundle bundle);

    View getLayoutView();

    void initContext(Context context);

    void initData();
}

model层

public abstract class AppDelegate implements IDelegate {
    public View mInflate;

    @Override
    public void create(LayoutInflater inflater, ViewGroup viewGroup, Bundle bundle) {
        mInflate = inflater.inflate(getLayoutId(), viewGroup, false);
    }

    public abstract int getLayoutId();
    @Override
    public View getLayoutView() {
        return mInflate;
    }
}

presenter view和model交互

public abstract class BaseActivityPresenter<T extends AppDelegate> extends AppCompatActivity {

    public T delegate;

    public abstract Class<T> getClassDelegate();

    public BaseActivityPresenter() {
        try {
            delegate = getClassDelegate().newInstance();
        } catch (IllegalAccessException e) {
            e.printStackTrace();
        } catch (InstantiationException e) {
            e.printStackTrace();
        }
    }


    @Override
    protected void onCreate(@Nullable Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        delegate.create(getLayoutInflater(), null, savedInstanceState);
        setContentView(delegate.getLayoutView());
        delegate.initContext(this);
        ButterKnife.bind(this);
        delegate.initData();
    }
}
