Question

我应该怎么做才能从AsyncTask中的onPostExecute方法向现有的线性布局中添加新的TextView（在代码中带有文本“ inf1”和“ inf2”）？

module.exports = function(Model, options) {
  Model.observe("before save", async function(ctx) {
    if (ctx.instance.id) return;

    const userId = ctx.options && ctx.options.accessToken && ctx.options.accessToken.userId;

    if (userId) {
      //... do stuff
    }
    else 
    {
      console.error("Failed to scope " + Model.name + " to user (null)");
    }
  });
};

找到视图，然后向其添加子视图：

    LinearLayout layout_named_feedFetch=(LinearLayout)findViewById(R.id.feedFetch);
    //or call the_parent_view_of_feedFetch.findViewById() if it's the child another view; 
    for(int x=0; x < result.length(); x++) {
        JSONObject collegeData = result.getJSONObject(x);
        inf1 = collegeData.getString("title");
        inf2 = collegeData.getString("text");
        //create the new views
        TextView tv=new TextView(getApplicationContext());
        //add them to where you want
        layout_named_feedFetch.addView(tv);
        //assign values to them
        tv.setText(inf1+" "+inf2);
    }

如何在AsyncTask的onPostExecute方法中使用'myLayout.addView（View v）'
