購物車 （二級列表）
效果：
一、先寫許可權
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
二、導依賴
Eventbus依賴:
compile 'org.greenrobot:eventbus:3.1.1'
gson依賴:
implementation 'com.google.code.gson:gson:2.8.5'
OkHttp依賴:
compile 'com.squareup.okhttp3:okhttp:3.9.0'
recyclerView依賴:
implementation 'com.android.support:recyclerview-v7:28.0.0'
glid依賴:
repositories { mavenCentral() maven { url 'https://maven.google.com' } } dependencies { compile 'com.github.bumptech.glide:glide:4.3.1' annotationProcessor 'com.github.bumptech.glide:compiler:4.3.1' }
接下來就是佈局和具體的程式碼了
一、Main的佈局
<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:app="http://schemas.android.com/apk/res-auto" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical" tools:context=".MainActivity"> <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="50dp" android:layout_alignParentBottom="true" android:background="@android:color/white" android:gravity="center_vertical"> <CheckBox android:id="@+id/checkbox2" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_centerVertical="true" android:layout_marginLeft="10dp" android:focusable="false" /> <TextView android:layout_width="wrap_content" android:layout_height="50dp" android:layout_centerVertical="true" android:layout_marginLeft="10dp" android:layout_toRightOf="@+id/checkbox2" android:gravity="center_vertical" android:text="全選" android:textSize="20sp" /> <LinearLayout android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_marginLeft="100dp" android:orientation="horizontal"> <TextView android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_marginLeft="10dp" android:text="合計 ：" /> <TextView android:id="@+id/tv_price" android:layout_width="wrap_content" android:layout_height="50dp" android:layout_marginLeft="10dp" android:paddingRight="10dp" android:text="0" android:textColor="@android:color/holo_red_light" /> <TextView android:layout_marginLeft="150dp" android:id="@+id/tv_num" android:layout_width="150dp" android:layout_height="50dp" android:background="@android:color/holo_red_dark" android:gravity="center" android:padding="10dp" android:text="結算(0)" android:textColor="@android:color/white" /> </LinearLayout> </RelativeLayout> </LinearLayout>
二、一級列表的佈局
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="10dp"
android:gravity="center_vertical"
android:orientation="horizontal">
<CheckBox
android:id="@+id/cb_parent"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginBottom="5dp"
android:layout_marginLeft="10dp"

android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="20dp"
android:text="12345678" />
</LinearLayout>
三、二級列表的佈局
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:gravity="center_vertical"
android:orientation="horizontal">
<CheckBox
android:id="@+id/cb_child"
android:layout_width="wrap_content"

</LinearLayout>
</LinearLayout>

四、加減框自定義view的佈局
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"

android:id="@+id/btn_add"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textSize="20sp"
android:text="+"/>
<EditText
android:id="@+id/et_et"
android:layout_width="50dp"
android:layout_height="wrap_content"
android:text="1"
android:textSize="20sp"/>
<Button
android:id="@+id/btn_del"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textSize="20sp"
android:text="-"/>
</LinearLayout>
五、Main的程式碼（用到的佈局檔案是Main佈局）
package com.gj.buycarej;
import android.app.Activity;
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.view.View;
import android.widget.CheckBox;
import android.widget.ExpandableListView;
import android.widget.TextView;
import com.gj.buycarej.adapter.StarExpanderAdapter;
import com.gj.buycarej.bean.GsonBean;
import com.gj.buycarej.bean.MessageEvent;
import com.gj.buycarej.bean.PriceAndCountEvent;
import com.gj.buycarej.core.IView;
import com.gj.buycarej.presenter.PresentCar;
import org.greenrobot.eventbus.EventBus;
import org.greenrobot.eventbus.Subscribe;
import java.util.ArrayList;
import java.util.List;
public class MainActivity extends AppCompatActivity implements IView {
private ExpandableListView elv;
ArrayList<GsonBean.DataBean> dataBeen = new ArrayList<>();
private CheckBox checkquan;
private List<GsonBean.DataBean.ListBean> lists;
ArrayList<List<GsonBean.DataBean.ListBean>> listBean = new ArrayList<>();
private StarExpanderAdapter adapter;
private TextView tv_price;
private TextView tv_num;
private PresentCar presentCar;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
//註冊一下
EventBus.getDefault().register(this);
//獲取控制元件
elv = (ExpandableListView) findViewById(R.id.elv);
checkquan = (CheckBox) findViewById(R.id.checkbox2);
tv_price = (TextView) findViewById(R.id.tv_price);
tv_num = (TextView) findViewById(R.id.tv_num);
//獲取資料
presentCar = new PresentCar();
presentCar.attachView(this);
presentCar.getNews();
checkquan.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
//設定全選
adapter.changeAllListCbState(checkquan.isChecked());
}
});
}
//銷燬方法
@Override
protected void onDestroy() {
super.onDestroy();
//eventBus銷燬
EventBus.getDefault().unregister(this);
if (presentCar!=null){
presentCar.detachView();
}
}
@Override
public void Success(String tag, List<GsonBean.DataBean> list) {
dataBeen.addAll(list);
for (int i = 0; i < dataBeen.size(); i++) {
GsonBean.DataBean bean = dataBeen.get(i);
lists = bean.getList();
listBean.add(lists);
}
adapter = new StarExpanderAdapter(MainActivity.this,dataBeen,listBean);
elv.setAdapter(adapter);
//隱藏二級列表前小三角
elv.setGroupIndicator(null);
//使二級列表一直展示
for (int i = 0; i <dataBeen.size() ; i++) {
elv.expandGroup(i);
}
}
@Override
public void Failed(String tag, Exception e) {
}
//必寫註解
@Subscribe
public void onMessageEvent(MessageEvent event) {
checkquan.setChecked(event.isChecked());
}
@Subscribe
public void onMessageEvent(PriceAndCountEvent event) {
tv_num.setText("結算(" + event.getCount() + ")");
tv_price.setText(event.getPrice() + "");
}
}
六、P層請求資料
package com.gj.buycarej.presenter;
import com.gj.buycarej.bean.GsonBean;
import com.gj.buycarej.core.Callback;
import com.gj.buycarej.core.IView;
import com.gj.buycarej.http.HttpUtils;
import java.util.HashMap;
import java.util.List;
import java.util.Map;
public class PresentCar {
private IView inv;
public void attachView(IView inv) {
this.inv = inv;
}
public void getNews() {
//type=top&key=dbedecbcd1899c9785b95cc2d17131c5
Map<String, String> map = new HashMap<>();
HttpUtils.getInstanse().get("http://120.27.23.105/product/getCarts?uid=100", map, new Callback() {
@Override
public void onSuccess(String tag, Object o) {
GsonBean bean = (GsonBean) o;
if (bean != null) {
List<GsonBean.DataBean> data = bean.getData();
inv.Success(tag, data);
}
}
@Override
public void onFailure(String tag, Exception e) {
inv.Failed(tag, e);
}
}, GsonBean.class, "news");
}
public void detachView() {
if (inv != null) {
inv = null;
}
}
}
七、用到的介面及自定義view
介面一、
package com.gj.buycarej.core;
public interface Callback {
void onSuccess(String tag,Object o);
void onFailure(String tag,Exception e);
}
介面二、
package com.gj.buycarej.core;
import com.gj.buycarej.bean.GsonBean;
import java.util.List;
public interface IView {
void Success (String tag, List<GsonBean.DataBean> list);
void Failed(String tag,Exception e);
}
自定義view（此處用到的佈局是加減的佈局檔案）
package com.gj.buycarej.core;
import android.content.Context;
import android.support.annotation.Nullable;
import android.util.AttributeSet;
import android.util.Log;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.widget.LinearLayout;
import com.gj.buycarej.R;
public class MyView extends LinearLayout {
private OnAddDelClickLstener lister;
private Button btn_add;
private Button txtAdd;
private EditText et_et;
private Button btn_del;
//定義一個對外開放的介面
public interface OnAddDelClickLstener{
void onAddClick(View v);
void onDelClick(View v);
}
public void setOnAddDelClickLstener(OnAddDelClickLstener lister){
if(lister!=null){
this.lister = lister;
}
}
public MyView(Context context) {
this(context,null);
}
public MyView(Context context, @Nullable AttributeSet attrs) {
this(context, attrs,0);
}
public MyView(Context context, @Nullable AttributeSet attrs, int defStyleAttr) {
super(context, attrs, defStyleAttr);
initView(context, attrs, defStyleAttr);
}
private void initView(Context context, AttributeSet attrs, int defStyleAttr) {
View.inflate(context, R.layout.item_jj,this);
btn_add = (Button) findViewById(R.id.btn_add);
btn_del = (Button) findViewById(R.id.btn_del);
et_et = (EditText) findViewById(R.id.et_et);
btn_del.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View view) {
Log.e("AddDeleteView","點選了減號");
lister.onDelClick(view);
}
});
btn_add.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View view) {
Log.e("txtAdd","點選了加號");
lister.onAddClick(view);
}
});
}
}
八、
package com.gj.buycarej.http;
import android.os.Handler;
import android.text.TextUtils;
import android.util.Log;

}
public static HttpUtils getInstanse() {
if (null == instanse) {
synchronized (HttpUtils.class) {
if (instanse == null) {
instanse = new HttpUtils();
}
}
}
return instanse;
}
public void get(String url, Map<String, String> map, final Callback callBack,
final Class cls, final String tag) {
// http://www.baoidu.com/login?mobile=11111&password=11111&age=1&name=zw
// 1.http://www.baoidu.com/login --------？ key=value&key=value
// 2.http://www.baoidu.com/login? --------- key=value&key=value

final StringBuffer sb = new StringBuffer();
sb.append(url);
if (TextUtils.isEmpty(url)) {
return;
}
// 如果包含？說明是2.3型別
if (url.contains("?")) {
// 如果包含？並且？是最後一位，對應是2型別
if (url.indexOf("?") == url.length() - 1) {
} else {
// 如果包含？並且？不是最後一位，對應是3型別
sb.append("&");
}
}
for (Map.Entry<String, String> entry : map.entrySet()) {
sb.append(entry.getKey())
.append("=")
.append(entry.getValue())
.append("&");
}
if (sb.indexOf("&") != -1) {
sb.deleteCharAt((sb.lastIndexOf("&")));
}
Log.i(TAG, "get:url " + sb.toString());
OkHttpClient client = new OkHttpClient.Builder().build();
Request request = new Request.Builder()
.get()
.url(sb.toString())
.build();
Call call = client.newCall(request);
call.enqueue(new okhttp3.Callback() {
@Override
public void onFailure(Call call, final IOException e) {
handler.post(new Runnable() {
@Override
public void run() {
callBack.onFailure(tag,e);
}
});
}
@Override
public void onResponse(Call call, Response response) throws IOException {
final String s = response.body().string();
handler.post(new Runnable() {
Object o;
@Override
public void run() {
if(TextUtils.isEmpty(s)){
o=null;
}else
{
o = new Gson().fromJson(s, cls);
}
callBack.onSuccess(tag,o);
}
});
}
});
}
}
