支付寶支付的接入就比微信的簡單了，開始表演！申請參數(shù)這些就不說了，簡簡單單
開始接入：1、將alipay-sdk-common/alipaySdk-xxxxxxxx.jar包放入項目應(yīng)用工程的libs目錄下2、在AndroidManifest.xml文件里面添加聲明：

<pre>
<activity
android:name="com.alipay.sdk.app.H5PayActivity"
android:configChanges="orientation|keyboardHidden|navigation"
android:exported="false"
android:screenOrientation="behind" >
</activity>
<activity
android:name="com.alipay.sdk.auth.AuthActivity"
android:configChanges="orientation|keyboardHidden|navigation"
android:exported="false"
android:screenOrientation="behind" >
</activity>
</pre>

需要的權(quán)限：
<pre>
<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" />
</pre>

添加混淆規(guī)則，在工程的proguard-project.txt文件下
<pre>
-libraryjars libs/alipaySDK-20150602.jar
-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 *;}
</pre>

基本配置好了以后就開始上主菜了

<pre>
//我這里使用OKhttp來做網(wǎng)絡(luò)訪問，將需要的參數(shù)傳遞給服務(wù)端小哥 // PAY_NET_URL 服務(wù)端地址
RequestCall requestCall= OkHttpUtils.get().url(Constants.PAY_NET_URL)
.addParams("userID", uid)
.addParams("appID", appid)
.addParams("productID", productID+"")
.addParams("productName",productName)
.addParams("productDesc",productDesc)
.addParams("money", "" + price)
.addParams("roleID", roleID)
.addParams("roleName", roleName)
.addParams("serverID",serverId)
.addParams("serverName",serverName)

.build();
requestCall.execute(new StringCallback() {
@Override
public void onError(Call call, Exception e, int i) {
Log.e("requestCall is onError",e.getMessage());
}

        @Override
        public void onResponse(String json, int i) {
         // 使用Gson解析
            result1 = new Gson().fromJson(json, Result.class);
            final String extension = result1.getData().getExtension();
            Runnable payRunnable = new Runnable() {
                @Override
                public void run() {
                // 這里調(diào)用支付寶api
                    PayTask alipay = new PayTask(mActivty);
                    Map<String, String> result = alipay.payV2(extension,true);
                    Log.i("msp", result.toString());
                    Message msg = new Message();
                    msg.what = SDK_PAY_FLAG;
                    msg.obj = result;
                    mHandler.sendMessage(msg);
                }
            };

            Thread payThread = new Thread(payRunnable);
            payThread.start();

        }
    });

</pre>
支付寶Handler（用來接收支付寶支付結(jié)果）
<pre>

private Handler mHandler = new Handler() {
@SuppressWarnings("unused")
public void handleMessage(Message msg) {
switch (msg.what) {
case SDK_PAY_FLAG: {
@SuppressWarnings("unchecked")
PayResult payResult = new PayResult((Map<String, String>) msg.obj);
/**
對于支付結(jié)果，請商戶依賴服務(wù)端的異步通知結(jié)果。同步通知結(jié)果，僅作為支付結(jié)束的通知。
*/
String resultInfo = payResult.getResult();// 同步返回需要驗證的信息
String resultStatus = payResult.getResultStatus();
// 判斷resultStatus 為9000則代表支付成功
if (TextUtils.equals(resultStatus, "9000")) {
Toast.makeText(mContext, "支付成功", Toast.LENGTH_SHORT).show();

            } else {
                // 判斷resultStatus 為非"9000"則代表可能支付失敗
                // "8000"代表支付結(jié)果因為支付渠道原因或者系統(tǒng)原因還在等待支付結(jié)果確認，最終交易是否成功以服務(wù)端異步通知為準（小概率狀態(tài)）
                if (TextUtils.equals(resultStatus, "8000")) {
                    Toast.makeText(mContext, "支付結(jié)果確認中", Toast.LENGTH_SHORT).show();
                } else {
                    // 其他值就可以判斷為支付失敗，包括用戶主動取消支付，或者系統(tǒng)返回的錯誤
                    Toast.makeText(mContext, "支付失敗", Toast.LENGTH_SHORT).show();
                }
            }
            break;
        }
        default:
            break;
    }
}
};//handler結(jié)束

</pre>

Result.class

<pre>

public class Result {

private DataBean data;
private int state;

public DataBean getData() {
    return data;
}

public void setData(DataBean data) {
    this.data = data;
}

public int getState() {
    return state;
}

public void setState(int state) {
    this.state = state;
}

public static class DataBean {


    private String extension;
    private long orderID;

    public String getExtension() {
        return extension;
    }

    public void setExtension(String extension) {
        this.extension = extension;
    }

    public long getOrderID() {
        return orderID;
    }

    public void setOrderID(long orderID) {
        this.orderID = orderID;
    }
}

}
</pre>

到這里就結(jié)束了，一般參數(shù)沒問題就可以開心的支付了。

ps： 要是寫的有問題希望大家提出我將虛心接受批評及積極改正！
