第一步：导入依赖包 implementation 'com.android.support:recyclerview-v7:25.3.1'
第二步：用 JSONArray 解析后台数据并setadapter
JSONArray jsonArray = jsonObject.getJSONArray("obj");
if (jsonArray.size() > 0) {
for (int i = 0; i < jsonArray.size(); i++) {
JSONObject jb = jsonArray.getJSONObject(i);
patientID = jb.getInteger("id");
patientName = jb.getString("name");
patientPhone = jb.getString("phone");
patientSFZNum = jb.getString("identityno");
PatientPhoneBean patientPhoneBean = new PatientPhoneBean();
patientPhoneBean.setPatientID(patientID);
patientPhoneBean.setPatientName(patientName);
patientPhoneBean.setPatientPhone(patientPhone);
patientPhoneBean.setPatientSFZNum(patientSFZNum);
patientPhoneList.add(patientPhoneBean);
}
phoneBean.setPhoneobj(patientPhoneList);
Message message = Message.obtain();
message.what = GETPATIENTPHONE_FLAG;
message.obj = phoneBean.getPhoneobj();
handler.sendMessage(message);
然后在 handleMessage处理收到的消息：
case GETPATIENTPHONE_FLAG:
getPatientPhoneAdapter.addData((List<PatientPhoneBean>) msg.obj);
getPatientPhoneRV.setAdapter(getPatientPhoneAdapter);
getPatientPhoneSwipeRL.setRefreshing(false);
break;
第三步：在Adapter里面的操作：
@Override
public void onBindViewHolder(@NonNull RecyclerView.ViewHolder holder, final int position) {
if (holder instanceof GetPatientPhoneAdapter.MyHolder) {
final PatientPhoneBean data = ppData.get(position);
((GetPatientPhoneAdapter.MyHolder) holder).tv_num.setText(data.getPatientID() + "");
((GetPatientPhoneAdapter.MyHolder) holder).tv_name.setText(data.getPatientName() + "");
((GetPatientPhoneAdapter.MyHolder) holder).tv_phone.setText(data.getPatientPhone() + "");
((GetPatientPhoneAdapter.MyHolder) holder).tv_sfznum.setText(data.getPatientSFZNum() + "");
//点击事件
((GetPatientPhoneAdapter.MyHolder) holder).ll_commitphone.setOnClickListener(new View.OnClickListener(){
@Override
public void onClick(View v) {
if (listener != null) {
listener.onClick(position,data.getPatientPhone() + "");
}}});
}}
//RecyclerView的点击事件
//一、在recycler的适配器中定义接口
public interface OnItemClickListener {
void onClick(int position, String phone);
}
private OnItemClickListener listener;
//第二步， 写一个公共的方法
public void setOnItemClickListener(OnItemClickListener listener) {
this.listener = listener;
}
