參考官方自定義插件使用方法傳送門
開發工具：Android Studio
1.下載微信SDK
傳送門
2.將jar導入libs包
3.寫Java，接收前端參數，實現微信小程序跳轉
參考微信說明文檔傳送門
package io.dcloud.HBuilder.wxapi;
import io.dcloud.common.DHInterface.IWebview;
import io.dcloud.common.DHInterface.StandardFeature;
import io.dcloud.common.util.JSUtil;
import org.json.JSONArray;
import com.tencent.mm.opensdk.modelbiz.WXLaunchMiniProgram;
import com.tencent.mm.opensdk.openapi.IWXAPI;
import com.tencent.mm.opensdk.openapi.WXAPIFactory;
public class MiniProgram extends StandardFeature {
@SuppressWarnings("deprecation")
//js同步: boolean launchMini(appId, programId, path="", type="")
public String launchMini(final IWebview pWebview, JSONArray array) {
String appId = array.optString(0);
String programId = array.optString(1);
String path = array.optString(2);
int type = array.optInt(3);
IWXAPI api = WXAPIFactory.createWXAPI(pWebview.getActivity(), appId);
WXLaunchMiniProgram.Req req = new WXLaunchMiniProgram.Req();
req.userName = programId; // 填小程序原始id (gh_開頭)
req.path = path; //拉起小程序頁面的可帶參路徑，不填默認拉起小程序首頁
req.miniprogramType = type;// 可選打開 開發版，體驗版和正式版 WXLaunchMiniProgram.Req.MINIPTOGRAM_TYPE_RELEASE
return JSUtil.wrapJsVar("" + api.sendReq(req), false);
}
}
5.增補自定義插件
io.dcloud.HBuilder.wxapi.MiniProgram
爲Java類地址
前端：
<!DOCTYPE HTML>
<html>
<head>
<meta charset="utf-8" />
<meta name="viewport" content="initial-scale=1.0, maximum-scale=1.0, user-scalable=no" />
<meta name="HandheldFriendly" content="true" />
<meta name="MobileOptimized" content="320" />
<title>微信小程序跳轉測試</title>
</head>
<body>
<div class="button" onclick="openMiniProgram()">打開微信小程序</div>
<script type="text/javascript">
function openMiniProgram(){
plus.bridge.execSync("mini-program", "launchMini", ["wxd930ea5d5a258f4f","gh_d43f693ca31f","","0"]);
}
</script>
</body>
</html>
別忘咯app需要關聯微信小程序哦！
