Need help here, about onPostExecute. If I want to put the update on textView what should be the code and what should I do?.

@Override
protected Value[] doInBackground(Integer... params) {
    ApiClient apiClient = new ApiClient(API_KEY);
    Variable batteryLevel = apiClient.getVariable(VARIABLE_ID);
    Value[] variableValues = batteryLevel.getValues();

    return variableValues;
}

@Override
protected void onPostExecute(Value[] variableValues) {
    // Update your views here
}

推荐答案

如果要从Ubidots到文本视图获取最后一个值.您可以尝试执行此操作，但是您必须先将Textview设置为OnCreate

If you want get last value from Ubidots to your textview. You can try this, but u must set the textview first OnCreate

@Override
        protected void onPostExecute(Value[] variableValues) {
            // Update your views here

            String status = Double.toString(variableValues[0].getValue());
//this is textview for show last value from ubidots
            mBatteryStatus.setText(status);

        }
    }
