虽然添加微信SDK也可以跳转，但是根据源码自己写的一个跳转更方便。
import android.app.Activity;import android.content.ContentResolver;import android.database.Cursor;import android.net.Uri;//跳转到微信小程序public class WXLaunchMiniUtil { private final Activity mActivity; public static final String MINIPTOGRAM_TYPE_RELEASE = "0"; public String appId;//微信开发者平台APPP的id public String userName;// 小程序原始id public String path;//拉起小程序页面的可带参路径，不填默认拉起小程序首页 public String miniprogramType;//0正式版 1开发版 2体验版 public WXLaunchMiniUtil(Activity mActivity) { this.mActivity = mActivity; } //跳转 public void sendReq() { ContentResolver resolver = mActivity.getContentResolver(); Uri uri = Uri.parse("content://com.tencent.mm.sdk.comm.provider/launchWXMiniprogram"); String[] path = new String[]{this.appId, this.userName, this.path, this.miniprogramType, ""}; Cursor cursor; if ((cursor = resolver.query(uri, null, null, path, null)) != null) { cursor.close(); } }}
使用方法：
WXLaunchMiniUtil miniUtil = new WXLaunchMiniUtil(mActivity);miniUtil.appId = wxxxxxxxxxxx;miniUtil.userName = "gh_xxxxxxxxxxxx";miniUtil.path = "pages/index/index";miniUtil.miniprogramType = WXLaunchMiniUtil.MINIPTOGRAM_TYPE_RELEASE;miniUtil.sendReq();
