分页加载PullToRefreshLayout+PullableListView

PullToRefreshLayout+PullableListView实现分页加载功能

1、修改布局文件（添加下拉刷新和上拉加载的布局）

<com.abcaaaaa.zyypay.ui.widget.pulltorefresh.PullToRefreshLayout
    android:id="@+id/pulltorefreshlayout"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_below="@id/rl_mid">

    <include layout="@layout/load_head" />

    <com.abcaaaaa.zyypay.ui.widget.pulltorefresh.PullableListView
        android:id="@+id/pullablelistview"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:divider="#E0E0E0"
        android:dividerHeight="2px" />

    <include layout="@layout/load_more" />

</com.abcaaaaa.zyypay.ui.widget.pulltorefresh.PullToRefreshLayout>

2、设置网络请求的工具类

/**
     *设置在不同情况下数据刷新的设置
     * @param requestTag
     * @param params
     * @param onDataListener
     * @param showLoad 加载框状态， 0表示弹出收起，1表示只弹出，2表示只收起
     * @param pullToRefreshLayout
     * @param requsetType  当数据位0时表示普通请求，为1时表示刷新请求，为2时表示加载请求
     * @return
     */
    public static RequestHandle doPost(final int requestTag, RequestParams params, final OnDataListener onDataListener, final int showLoad,
                                       final PullToRefreshLayout pullToRefreshLayout, final int requsetType) {
        // 重连次数,超时时间
        client.setMaxRetriesAndTimeout(0, 5000);
        return client.post(URL, params, new JsonHttpResponseHandler() {
            @Override
            public void onStart() {
                super.onStart();
                onDataListener.onStart(requestTag, showLoad);
            }

            @Override
            public void onSuccess(int statusCode, Header[] headers, JSONObject response) {
                super.onSuccess(statusCode, headers, response);
                if (requsetType == 1) {
                    pullToRefreshLayout.refreshFinish(PullToRefreshLayout.SUCCEED);
                }
//                else if (requsetType == 2){
//                    pullToRefreshLayout.loadmoreFinish(PullToRefreshLayout.SUCCEED);
//                }
                onDataListener.onSuccess(requestTag, response, showLoad);
            }

            @Override
            public void onFailure(int statusCode, Header[] headers, Throwable throwable, JSONObject errorResponse) {
                super.onFailure(statusCode, headers, throwable, errorResponse);
                if (requsetType == 1) {
                    pullToRefreshLayout.refreshFinish(PullToRefreshLayout.FAIL);
                } else if (requsetType == 2) {
                    pullToRefreshLayout.loadmoreFinish(PullToRefreshLayout.FAIL);
                }
                onDataListener.onFailure(requestTag, errorResponse, showLoad);
            }

            @Override
            public void onCancel() {
                super.onCancel();
                onDataListener.onCancel(requestTag, showLoad);
            }
        });
    }

3、获取网络请求的数据（有添加刷新分页功能）

//获取结算列表数据---------改为有刷新加载的请求 20170609修改
public RequestHandle getSettlementList(OnDataListener onDataListener, PullToRefreshLayout pullToRefreshLayout, int requestType,
                                       int page, int requesTag, int showLoad) {
    String randomCode = SharedPreferencesUtlis.getString(mContext, ConstantUtlis.SP_RANDOMCODE, "");
    HashMap<String, Object> hashMap = new HashMap<>();
    if (page > 0) {
        hashMap.put("页数", page + "");
    } else {
        hashMap.put("页数", 1 + "");
    }
    hashMap.putAll(CommonUtlis.loadMap(ConstantUtlis.SP_INFO_JSON));
    RequestParams params = new RequestParams();
    params.add("func", FUNC_SETTLEMENTLIST);
    params.add("words", randomCode + EnDecryptUtlis.aesEncrypt(JsonUtils.createJSON(hashMap).toString(), randomCode));
    return HttpManager.doPost(requesTag, params, onDataListener, showLoad, pullToRefreshLayout, requestType);
}

4、在实现分页刷新加载功能的页面完成如下设置
4.1声明相关的设置

private PullToRefreshLayout pullToRefreshLayout;
private PullableScrollView pullablescrollview;
private ListViewForScrollView mListView;
private TextView mTvNoData;
private TextView tv_settlement_gosettle, tv_settlement_lasttime;
private List<String[]> list = new ArrayList<>();
private CommonAdapter mSettlementListAdapter;
private String lastSettlementTime;
private int page = 0;

4.2刷新功能的具体实现

/**
 * @param requestType 请求类型，初始请求=0，刷新=1，加载=2
 * @param page        页数
 * @param requestTag  请求tag,请求成功后用于区分是哪个请求
 * @param showLoad    是否显示请求加载框 0--显示， -1--不显示
 */
private void request(int requestType, int page, int requestTag, int showLoad) {
    requestHandleArrayList.add(requestAction.getSettlementList(this, pullToRefreshLayout, requestType, page, requestTag, showLoad));
}
@Override
public void onRefresh(PullToRefreshLayout pullToRefreshLayout) {
    if (!list.isEmpty()) {
        mSettlementListAdapter.notifyDataSetChanged();
    }
    list.clear();
    request(1, 0, 2, -1);
}
@Override
public void onLoadMore(PullToRefreshLayout pullToRefreshLayout) {
    if (page > 0) {
        request(2, page + 1, 3, -1);
    } else {
        MToast.showToast(mContext, "已无数据加载");
        pullToRefreshLayout.loadmoreFinish(PullToRefreshLayout.FAIL);
    }
}
4.3处理网络请求返回的数据

/**
 * 处理请求返回数据
 *
 * @param response
 * @param isLoadMore
 */
private void processResponseData(JSONObject response, boolean isLoadMore) throws JSONException {
    Log.e("结算单列表", response.toString());
    lastSettlementTime = response.getString("上次结算时间");
    tv_settlement_lasttime.setText(lastSettlementTime);
    int num = Integer.parseInt(response.getString("条数"));
    if (num != 0) {//有可展示的数据
        JSONArray jsonArray = response.getJSONArray("列表");
        for (int i = 0; i < jsonArray.length(); i++) {
            String[] a = new String[6];
            JSONObject jsonObject = (JSONObject) jsonArray.get(i);
            a[0] = jsonObject.getString("真实名");
            a[1] = jsonObject.getString("交易金额");
            a[2] = jsonObject.getString("到账金额");
            a[3] = jsonObject.getString("结算单号");
            a[4] = jsonObject.getString("开始时间");
            a[5] = jsonObject.getString("结束时间");
            list.add(a);
        }
        page = num == 10 ? Integer.parseInt(response.getString("页数")) : 0;
        mListView.setVisibility(View.VISIBLE);
        mTvNoData.setVisibility(View.GONE);
        if (isLoadMore) {
            pullToRefreshLayout.loadmoreFinish(PullToRefreshLayout.SUCCEED);
            mSettlementListAdapter.notifyDataSetChanged();
        } else {
            setAdapter();
        }
    } else {//数据条数为0
        if (isLoadMore) {
            MToast.showToast(mContext, "已无数据加载");
            pullToRefreshLayout.loadmoreFinish(PullToRefreshLayout.FAIL);
        } else {
            mListView.setVisibility(View.GONE);
            mTvNoData.setVisibility(View.VISIBLE);
            mTvNoData.setText("无数据");
        }
    }
}
4.4网络请求成功，根据tag区分请求类别

@Override
    public void requestSuccess(int requestTag, JSONObject response, int showLoad) throws JSONException {
        super.requestSuccess(requestTag, response, showLoad);
        switch (requestTag) {
            case 1:
                processResponseData(response, false);
                break;
            case 2:
                processResponseData(response, false);
                break;
            case 3:
                processResponseData(response, true);
                break;
            default:
                break;
        }
    }
4.5设置界面展示的adpter

 private void setAdapter() {
        mSettlementListAdapter = new CommonAdapter<String[]>(SettlementActivity.this, R.layout.item_settlement, list) {
            @Override
            public void convert(final ViewHolder holder, String[] strings) {
                holder.setText(R.id.tv_settlement_name, strings[0]);
                holder.setText(R.id.tv_settlement_oddNum, strings[3]);
                holder.setText(R.id.tv_settlement_starttime, strings[4]);
                holder.setText(R.id.tv_settlement_endtime, strings[5]);
                holder.setText(R.id.tv_jiaoyi, strings[1]);
                holder.setText(R.id.tv_daozhang, strings[2]);
            }
        };//给listview中设置数据
        mListView.setAdapter(mSettlementListAdapter);
        //设置分隔线
        mListView.setDivider(new ColorDrawable(Color.rgb(243, 243, 243)));//#F3F3F3
        mListView.setDividerHeight(16);
　　　　//点击listview中的子控件跳转到对应的子界面
        mListView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
                Intent intent = new Intent(SettlementActivity.this, SettlementDetailActivity.class);
                intent.putExtra("name", list.get(position)[0]);
                intent.putExtra("oddNum", list.get(position)[3]);
                intent.putExtra("start", list.get(position)[4]);
                intent.putExtra("end", list.get(position)[5]);
                intent.putExtra("jiaoyi", list.get(position)[1]);
                intent.putExtra("daozhang", list.get(position)[2]);
                startActivity(intent);
            }
        });
    }
4.6其他相关设置

在initData（方法中）
pullablescrollview.smoothScrollTo(0, 0);//默认listview会滑倒顶部位置，这里设置为ScrollView的开始位置
数据刷新时，集合数据清空，重新进行网络请求

@Override
protected void onResume() {
    super.onResume();
    list.clear();
    request(0, 0, 1, 0);
}
