Question

我尝试使用Snackbar，但它需要一个视图，我已将mainlayout定义为View对象。并在Json响应完成时使用。但我没有看到任何小吃棒弹出窗口？有办法处理吗？下面是解析JSON响应时的处理方式。

public CityWeather parseJSONResponse(JSONObject response){
    cityWeather=new CityWeather();

    Log.d(LOG_TAG,"parse1");

    JSONObject resp= response;
    JSONObject detailJo;
    JSONObject cityJo;
    JSONObject aqiJo;
    String aqi;
    String city;
    String nowtemp;
    String condcd;
    String pm25;
    try {
        Log.d(LOG_TAG,"start parse");
        //Log.d(LOG_TAG,resp.toString());
        JSONArray weatherarrary = resp.getJSONArray(KEY_API);

        Log.d(LOG_TAG,"start parse2");

        //get Details
        detailJo=weatherarrary.getJSONObject(0);

        Log.d(LOG_TAG,"start parse3");

        //getAQI
        //Log.d(LOG_TAG,detailJo.toString());
        cityJo=detailJo.getJSONObject(KEY_AQI);

        Log.d(LOG_TAG,"after send json true");

        //when city not found
        if (cityJo==null){

            Log.d(LOG_TAG,"parse fail");
            return cityWeather;
        }

        aqiJo=cityJo.getJSONObject(KEY_CITY);
        Log.d(LOG_TAG,aqiJo.toString());

        aqi=aqiJo.getString(KEY_AQI);
        pm25=aqiJo.getString(KEY_PM25);

        Log.d(LOG_TAG,"parse succss1"+aqi+" "+pm25);

        //get City
        cityJo=detailJo.getJSONObject(KEY_BASIC);
        city=cityJo.getString(KEY_CITY);

        Snackbar.make(mainview,city+"添加成功",Snackbar.LENGTH_SHORT);

        //get now temp
        cityJo=detailJo.getJSONObject(KEY_NOW);
        nowtemp=cityJo.getString(KEY_TMP);
        Log.d(LOG_TAG,"parse succss2"+city+" "+nowtemp);
        //
        cityJo=cityJo.getJSONObject(KEY_COND);
        condcd=cityJo.getString(KEY_CODE);
        Log.d(LOG_TAG,"parse succss3"+condcd);
        cityWeather=new CityWeather(city,aqi,pm25,Integer.parseInt(nowtemp),Integer.parseInt(condcd));

    }catch (JSONException je){
        Log.d(LOG_TAG,"JSONexp"+je.toString());
    }

    Log.d(LOG_TAG,"parse succss4");
    return cityWeather;
}

您没有通过Snackbar

显示show()

检查更改后是否仍有问题：

Snackbar.make(mainview,city+"添加成功",Snackbar.LENGTH_SHORT);

要：

Snackbar.make(mainview,city+"添加成功",Snackbar.LENGTH_SHORT).show();

如何在Json响应后使用Snackbar？
