社區項目開發小結（一）
（10.1-11.30）項目開發需求以及解決方案小結。
- Activity多級回跳
//重寫PresentActivity中的onActivityResult方法，對返回結果進行響應
@Override
protected void onActivityResult(int requestCode , int resultCode , Intent data ){
switch (requestCode){
case targetActivityRequestCode :
if( resultCode == 1){
String payResult = data.getStringExtra("PayResult");
if(payResult.equals("...")) {
//onBackPressed();
}
}
}
}
//啓動目標Activity（要點：使用startActivityForResult方法啓動）
Intent intent = new Intent(PresentActivity, TargetActivity.class);
intent.putExtra("Key", value);
startActivityForResult(intent,requestCode);//requestCode用作標記返回信息來自哪個TargetActivity
//((Activity)mContext).startActivityForResult(intent,1);//adapter啓動需要對mContext進行強制類型轉換
//TargetActivity的返回跳轉
private void backLastActivity(boolean paySuccess) {
Intent intent = new Intent();
if (paySuccess) {
intent.putExtra("PayResult", "Success");
} else {
intent.putExtra("PayResult", "Fail");
}
setResult(RESULT_OK, intent);
finish();
}
- Recycler上拉分頁加載以及下拉刷新
該需求的實現使用RecyclerView與第三方插件BRVAH鏈接：https://www.jianshu.com/p/b343fcff51b0相結合的方式- build.gradle 配置說明
添加資源庫添加資源庫maven { url “https://jitpack.io” }
添加依賴:compile ‘com.github.CymChad:BaseRecyclerViewAdapterHelper:VERSION_CODE’ - Adapter
繼承BaseQuickAdapter，重寫父類的PaymentRecordRvAdapter、convert方法
- build.gradle 配置說明
//具體詳細信息請查看[鏈接](https://www.jianshu.com/p/b343fcff51b0)
public class PaymentRecordRvAdapter extends BaseQuickAdapter<PaymentRecordListBean.DataBean,BaseViewHolder> {
private Context mContext;
/**
* @param layoutResId The layout resource id of each item. //內容的佈局
* @param data A new list is created out of this one to avoid mutable list //數據源
*/
public PaymentRecordRvAdapter(int layoutResId, List<DataBean> data，Context mContext) {
super(layoutItemResId,dataBeans);
this.mContext = mContext;
}
@Override
protected void convert(BaseViewHolder helper, DataBean itemData) {
ImageView imageView = helper.getView(R.id.iv_icon);
Glide.with(mContext).load(item.getIcon()).apply(new RequestOptions().centerCrop()).into(imageView);
helper.setText(R.id.tv_charge_type,item.getExpenseName())
.setText(R.id.tv_time,DateUtils.formatDate(item.getBillTime(),DateUtils.DB_DATA_FORMAT))；
}
}
- layout.xml
//RecyclerView結合SwipeRefreshLayout實現下拉刷新功能
<android.support.v4.widget.SwipeRefreshLayout
android:id="@+id/srl_refresh"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<android.support.v7.widget.RecyclerView
android:layout_marginTop="@dimen/y15"
android:id="@+id/rv_payment_record"
android:layout_width="match_parent"
android:layout_height="wrap_content"/>
</android.support.v4.widget.SwipeRefreshLayout>
- .Activity
/**Description:初始化下拉刷新監聽，整個生命週期有效*/
protected void initSwipeRefreshLayoutListener(){
swipeRefreshLayout.setOnRefreshListener(new SwipeRefreshLayout.OnRefreshListener() {
@Override
public void onRefresh() {
......
adapterDataBeans.clear();//清空數據
quickAdapter.replaceData(adapterDataBeans);//調用QuickAdapter的replaceData通知數據清空
quickAdapter.setEnableLoadMore(true);//重新啓動下拉分頁加載響應
requestRecyclerDate();//啓動刷新後初次數據加載
}
});
}
//初始化QuickAdapter監聽
@Override
public void initBrvahListener() {
//item點擊事件監聽
quickAdapter.setOnItemClickListener(new BaseQuickAdapter.OnItemClickListener() {
@Override
public void onItemClick(BaseQuickAdapter adapter, View view, int position) {
//do something
}
});
//上拉請求數據監聽
quickAdapter.setOnLoadMoreListener(new BaseQuickAdapter.RequestLoadMoreListener() {
@Override
public void onLoadMoreRequested() {
//上拉請求開始前，需要停止swipeRefreshLayout的下拉刷新響應
swipeRefreshLayout.setEnabled(false);
requestRecyclerDate();
//上拉刷新結束後，需要開啓swipeRefreshLayout的下拉刷新響應
swipeRefreshLayout.setEnabled(true);
}
}, recyclerView);
//設置該方法，初次加載數據不足時，系統即會停止響應下次上拉加載數據請求
quickAdapter.disableLoadMoreIfNotFullPage();
}
/**Description:添加分頁數據*/
protected void addAdapterData(List<T> data){
if (data.size() != 0) {
pageNum++;
adapterDataBeans.addAll(data);
if (data.size() != PAGE_SIZE)
/**Description:完成本次請求，關閉上拉請求監聽響應*/
quickAdapter.loadMoreEnd();
else
/**Description:完成本次請求*/
quickAdapter.loadMoreComplete();
} else {
/**Description:完成本次請求，關閉上拉請求監聽響應*/
quickAdapter.loadMoreEnd();
}
}

Alipay集成
3.1、導入開資源
包下載地址:開發包
3.2、導入開資源
將AlipaySdk******.jar包放入應用工程libs目錄
![在這裏插入圖片描述]()
3.3、添加依賴
compile files(‘libs/alipaySdk-20170725.jar’)
3.4、配置Manifest文件
<activity
android:name="com.alipay.sdk.app.H5PayActivity"
android:configChanges="orientation|keyboardHidden|navigation|screenSize"
android:exported="false"
android:screenOrientation="behind"
android:windowSoftInputMode="adjustResize|stateHidden" >
</activity>
<activity
android:name="com.alipay.sdk.app.H5AuthActivity"
android:configChanges="orientation|keyboardHidden|navigation"
android:exported="false"
android:screenOrientation="behind"
android:windowSoftInputMode="adjustResize|stateHidden" >
3.5、權限聲明
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
<uses-permission android:name="android.permission.READ_PHONE_STATE" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
3.6、混淆規則
在商戶應用工程的proguard-project.txt（proguard-rules.pro）裏添加以下相關規則：
-keep class com.alipay.android.app.IAlixPay{*;}
-keep class com.alipay.android.app.IAlixPay$Stub{*;}
-keep class com.alipay.android.app.IRemoteServiceCallback{*;}
-keep class com.alipay.android.app.IRemoteServiceCallback$Stub{*;}
-keep class com.alipay.sdk.app.PayTask{ public *;}
-keep class com.alipay.sdk.app.AuthTask{ public *;}
-keep class com.alipay.sdk.app.H5PayCallback {
<fields>;
<methods>;
}
-keep class com.alipay.android.phone.mrpc.core.** { *; }
-keep class com.alipay.apmobilesecuritysdk.** { *; }
-keep class com.alipay.mobile.framework.service.annotation.** { *; }
-keep class com.alipay.mobilesecuritysdk.face.** { *; }
-keep class com.alipay.tscenter.biz.rpc.** { *; }
-keep class org.json.alipay.** { *; }
-keep class com.alipay.tscenter.** { *; }
-keep class com.ta.utdid2.** { *;}
-keep class com.ut.device.** { *;}
3.7、設置環境
沙箱環境在super.onCreate(savedInstanceState);方法調用前調用EnvUtils.setEnv(EnvUtils.EnvEnum.SANDBOX);
生產環境、去掉EnvUtils.setEnv(EnvUtils.EnvEnum.SANDBOX);調用
3.8、調用Alipay接口(必須在子線程中調用)
Runnable payRunable = new Runnable() {
@Override
public void run() {
PayTask alipay = new PayTask(activity);
Map<String, String> result = alipay.payV2(signature, true);
Message msg = new Message();
msg.what =msgWhat;
msg.obj = result.get("resultStatus");
mHandler.sendMessage(msg);
}
};
Thread payThread = new Thread(payRunable);
payThread.start();
