自定义加减View:
public class JiaJianView extends LinearLayout implements View.OnClickListener {

//商品数量

}
//先给初始值赋值

public interface OnCountChange {

presenter层:
public class IPresenterImpl implements IPresenter {
private IView iView;
private IModelImpl iModel;
public IPresenterImpl(IView iView) {
this.iView = iView;
iModel = new IModelImpl();
}
@Override
public void requestData(String murl) {
iModel.startRequestData(murl, new MyCallBack() {
@Override
public void setData(Object data) {
iView.showRequestData(data);
}
});
}
}
Model:
public class IModelImpl implements IModel {
private MyCallBack mcallBack;
private Handler mhandler = new Handler(){
@Override
public void handleMessage(Message msg) {
super.handleMessage(msg);
if(msg.what==0){
String jsonStr = (String) msg.obj;
Gson gson = new Gson();
Work work = gson.fromJson(jsonStr,Work.class);
mcallBack.setData(work.getData());
}
}
};
@Override
public void startRequestData(final String murl, MyCallBack callBack) {
this.mcallBack = callBack;
new Thread(new Runnable() {
@Override
public void run() {
MyHttpUntils.getInstance().getAsync(murl, new Callback() {
@Override
public void onFailure(Call call, IOException e) {
Log.e("onFailure",e.getMessage()+"onFailure");
}
@Override
public void onResponse(Call call, Response response) throws IOException {
String data = response.body().string();
mhandler.sendMessage(mhandler.obtainMessage(0,data));
}
});
}
}).start();
}
}
不要忘了 布局文件里checkbox 设置 focusable 为false
CheckBox
android:id="@+id/Group_CB"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
-- focusable设置不强焦点 --
android:focusable="false"
View层在main层回调方法:
@Override
public void showRequestData(Object data) {
mdatas = (List) data;
adapter.setMdatas(mdatas);
//初试化时展开列表
for(int i=0;i
