這篇文章將為大家詳細講解有關使用ExpandableListView怎么實現一個二級列表購物車，文章內容質量較高，因此小編分享給大家做個參考，希望大家閱讀完這篇文章后對相關知識有一定的了解。
導入依賴
compile 'com.google.code.gson:gson:2.8.2' compile 'com.squareup.okhttp3:okhttp:3.9.0'
記得要把okhttp的原生文件夾復制進去，話不多說請看代碼：
MainActivity布局：
<ExpandableListView android:id="@+id/elv" android:layout_width="match_parent" android:layout_height="match_parent" android:layout_weight="1" /> <RelativeLayout android:layout_width="match_parent" android:layout_height="40dp"> <CheckBox android:id="@+id/cb" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_centerVertical="true" android:text="全選" /> <TextView android:id="@+id/tvTotal" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_centerVertical="true" android:layout_marginLeft="15dp" android:layout_toRightOf="@id/cb" android:text="合計:" /> <TextView android:id="@+id/tvCount" android:layout_width="100dp" android:layout_height="match_parent" android:layout_alignParentRight="true" android:layout_centerVertical="true" android:background="#ff0000" android:gravity="center" android:text="去結算(0)" android:textColor="#ffffff" /> </RelativeLayout>
適配器的Group布局：
<CheckBox android:id="@+id/cb_group" android:layout_width="wrap_content" android:layout_height="wrap_content" /> <TextView android:id="@+id/tv_group" android:layout_width="match_parent" android:layout_height="40dp" android:gravity="center_vertical" android:text="111"/>
適配器child布局：
<CheckBox android:id="@+id/cb_child" android:layout_width="wrap_content" android:layout_height="wrap_content" /> <ImageView android:id="@+id/iv" android:layout_width="100dp" android:layout_height="100dp" /> <LinearLayout android:layout_width="0dp" android:layout_height="wrap_content" android:layout_weight="1" android:orientation="vertical"> <TextView android:id="@+id/tv_title" android:layout_width="wrap_content" android:layout_height="wrap_content" /> <TextView android:id="@+id/tv_subhead" android:layout_width="wrap_content" android:layout_height="wrap_content" /> <TextView android:id="@+id/tvSubhead" android:layout_width="wrap_content" android:layout_height="wrap_content" /> <LinearLayout android:layout_width="match_parent" android:layout_height="wrap_content" android:gravity="center_vertical" android:orientation="horizontal"> <TextView android:id="@+id/tvPrice" android:layout_width="wrap_content" android:layout_height="wrap_content" /> <ImageView android:layout_marginLeft="10dp" android:id="@+id/ivDel" android:layout_width="25dp" android:layout_height="25dp" android:background="@drawable/iv_del" /> <TextView android:id="@+id/tvNum" android:layout_width="wrap_content" android:layout_height="wrap_content" android:textSize="25sp" android:layout_marginLeft="3dp" android:layout_marginRight="3dp" android:text="1"/> <ImageView android:id="@+id/ivAdd" android:layout_width="25dp" android:layout_height="25dp" android:background="@drawable/iv_add" /> </LinearLayout> </LinearLayout> <TextView android:id="@+id/btDel" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="刪除" />
接下來看代碼：
用MVP獲取的數據首先先在項目里創建三個文件夾分別是：model、view、persenter
model頁面代碼傳的參數：
public interface GoWuCheModel {
public void get(String uid, Callback callback);
}model頁面的代碼：
public class MyGoWuCheModel implements GoWuCheModel {
@Override
public void get(String uid, Callback callback) {
HashMap<String, String> map = new HashMap<>();
map.put("uid", uid);
OkHttp3Utils.doPost("http://120.27.23.105/product/getCarts?source=android", map, callback);
}
}view頁面的代碼：
public interface GoWuCheView {
public void success(ShopBean bean);
public void failuer(Exception e);
}persenter頁面的代碼：
public class GoWuChePersenter {
GoWuCheView view;
private final MyGoWuCheModel model;
public GoWuChePersenter(GoWuCheView view) {
this.view = view;
model = new MyGoWuCheModel();
}
public void getData(String uid) {
model.get(uid, new OnUiCallback() {
@Override
public void onFailed(Call call, IOException e) {
if (view != null) {
view.failuer(e);
}
}
@Override
public void onSuccess(String result) {
Gson gson = new Gson();
ShopBean bean = gson.fromJson(result, ShopBean.class);
view.success(bean);
}
});
}
