Question

我正在尝试获取温度和条件等天气详情，我无法显示它们但是我能够在我的日志猫代码中看到它们。

以下是我的代码

cond = (TextView) findViewById(R.id.condDescr);
 temp = (TextView) findViewById(R.id.tempText);
temp.setText("HI How are you");

JSONWeatherTask task = new JSONWeatherTask();
    task.execute(new String[]{city});   

private class JSONWeatherTask extends AsyncTask<String, Void, Weather> {

    @Override
    protected Weather doInBackground(String... params) {
        Weather weather = new Weather();
        String data = ( (new WeatherHttpClient()).getWeatherData(params[0]));

        try {
            weather = JSONWeatherParser.getWeather(data);

            // Let's retrieve the icon
            //weather.iconData = ( (new WeatherHttpClient()).getImage(weather.currentCondition.getIcon()));

        } catch (JSONException e) {             
            e.printStackTrace();
        }
        return weather;

}
    @Override
    protected void onPostExecute(Weather weather) {         
        super.onPostExecute(weather);

        if (weather.iconData != null && weather.iconData.length > 0) {
            Bitmap img = BitmapFactory.decodeByteArray(weather.iconData, 0, weather.iconData.length); 
            //imgView.setImageBitmap(img);
        }


        String str1 = (weather.currentCondition.getCondition() + "(" + weather.currentCondition.getDescr() + ")");
        //temp.setText("" + Math.round((weather.temperature.getTemp() - 273.15)) + "�C");**(I have tried this one too)**
        String str2 = ("" + weather.currentCondition.getHumidity() + "%");
    Log.w("myApp", str1);
        Log.w("mytemp", str2);
        cond.setText(str1);
        temp.setText(str2);

        //temp.setText("" + Math.round((weather.temperature.getTemp() - 273.15)) + "�C");

    }

我的XML文件

我也尝试过手动数据集，但它对我不起作用。我不知道我的错误是什么，任何人都可以告诉我如何解决这个问题。

要调用ASyncTask的方法doInBackground，您需要添加task.execute(params)。 params可以是String或多个Strings，由

分隔

在您的情况下，您应该传递执行getWeatherData（）方法所需的数据。

android设置文本对我不起作用
