Android 支付寶，微信支付
https://docs.open.alipay.com/204
https://pay.weixin.qq.com/wiki/doc/api/app/app.php?chapter=8_1
1、配置
android {
compileSdkVersion 27
defaultConfig {
resValue("string", "wx_appid", "wxa----------------") //此處填入自己appid,必須
}
}
dependencies {
implementation 'com.tencent.mm.opensdk:wechat-sdk-android-without-mta:5.1.4' //微信支付
implementation files('libs/alipaySdk-xxxx.jar') //支付寶
}
2、復(fù)制資源
1、支付寶jar包下載地址：https://docs.open.alipay.com/54/104509
（此資源較敏感，防止第三方修改，本文不提供，僅提供官網(wǎng)下載地址，下載后放入[project]/[model]/libs目錄中，1中引用需要修改為jar包名稱）。
2、在主包下面新建包wxapi,新建類WXPayEntryActivity.java
package com.xxx.wxapi;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.util.Log;
import com.xxx.utils.PayUtils;
import com.tencent.mm.opensdk.constants.ConstantsAPI;
import com.tencent.mm.opensdk.modelbase.BaseReq;
import com.tencent.mm.opensdk.modelbase.BaseResp;
import com.tencent.mm.opensdk.openapi.IWXAPI;
import com.tencent.mm.opensdk.openapi.IWXAPIEventHandler;
import com.tencent.mm.opensdk.openapi.WXAPIFactory;
/**
* Created by 林少 on 2016/6/22.
*/
public class WXPayEntryActivity extends Activity implements IWXAPIEventHandler {
public IWXAPI api;
public static PayUtils.WxPayNotify notify;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
api = WXAPIFactory.createWXAPI(this, getString(getResources().getIdentifier("wx_appid", "string", getPackageName())));
api.handleIntent(getIntent(), this);
}
@Override
protected void onNewIntent(Intent intent) {
super.onNewIntent(intent);
setIntent(intent);
api.handleIntent(intent, this);
}
@Override
public void onReq(BaseReq req) {
}
@Override
public void onResp(BaseResp resp) {
if (resp.getType() == ConstantsAPI.COMMAND_PAY_BY_WX) {
if (resp.errCode == 0) {
notify.success();
} else {
notify.failure();
}
finish();
}
}
}
AndroidManifest.xml添加
<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
android:name="com.alipay.sdk.app.H5AuthActivity"
android:configChanges="orientation|keyboardHidden|navigation"
android:exported="false"
android:screenOrientation="behind"
android:windowSoftInputMode="adjustResize|stateHidden" />
<activity
android:name=".wxapi.WXPayEntryActivity"
android:exported="true"
android:launchMode="singleTop" />
3、將下面工具類放入項(xiàng)目中,代碼為kotlin編寫，如需要轉(zhuǎn)換為java，請(qǐng)留言

支付寶
//back.data為后臺(tái)返回
PayUtils.alipayPay(this@PayVipActivity, back.data, object : PayUtils.AlipayNotify {
override fun success() {
T("支付成功")
finish()
}
override fun loadinging() {
T("支付結(jié)果確認(rèn)中，請(qǐng)勿返回")
}
override fun failure() {
T("支付失敗，請(qǐng)重試")
}
})
微信
//back.data為后臺(tái)返回簽名過的對(duì)象
PayUtils.wxPayMethod(this@PayVipActivity, back.data, object : PayUtils.WxPayNotify {
override fun success() {
T("支付成功")
finish()
}
override fun failure() {
T("支付失敗，請(qǐng)重試")
}
})
