大佬们，我是刚学JAVA。这个问题百度了一个星期找不到解决方法，无奈求助大佬们。

我想要在MainXposed类里面发送广播。但是MainXposed类里面MainActivity要怎么获取啊？


这是MainXposed类

    //hook数据库插入操作
    private void hookDatabaseInsert(final XC_LoadPackage.LoadPackageParam loadPackageParam) {
        Class<?> classDb = XposedHelpers.findClassIfExists("com.tencent.wcdb.database.SQLiteDatabase", loadPackageParam.classLoader);

          XposedHelpers.findAndHookMethod(classDb, "insertWithOnConflict", String.class, String.class, ContentValues.class, int.class, new XC_MethodHook() {
            @Override
            protected void afterHookedMethod(MethodHookParam param) throws Throwable {
                String tableName = (String) param.args[0];
                ContentValues contentValues = (ContentValues) param.args[2];
                String strTalker = contentValues.getAsString("talker");//说话人ID
                int isSend = contentValues.getAsInteger("isSend");//1：是不是自己发送的消息

                if ((tableName.equals("message")) && (isSend == 0)){   //是微信消息&&是某群消息
                    WeChatReply wechat = new WeChatReply();
                    wechat.sendIntent(activity,strTalker,"自动回复");
                }
            }
        });
    }

这是WeChatReply 类

public class WeChatReply extends AppCompatActivity {

    public void sendIntent (Activity act,String addressee,String text){
        Intent intent=new Intent("toTasker");
        Bundle bundle = new Bundle();
        bundle.putString("sean1", addressee);
        bundle.putString("sean2", text);
        intent.putExtras(bundle);
        act.sendBroadcast(intent);
    }
}

大佬，你这个我看不懂啊，
我的问题前两天已经解决了。
看了 奋进的代码 大佬的教程。还是谢谢你，对了你的代码是啥意思


XposedHelpers.findAndHookMethod(ContextThemeWrapper.class, "attachBaseContext",Context.class, new XC_MethodHook() {
            @Override
            protected void beforeHookedMethod(MethodHookParam param) throws Throwable {
                context=(Context) param.args[0];
            }
        });
