Question

class EndpointsAsyncTask extends AsyncTask<Pair<Context, Integer>, Void, Integer> {
    private static MyApi myApiService = null;
    private Context context;
    @Override
    protected Integer doInBackground(Pair<Context, Integer>... params) {
        if(myApiService == null) {  // Only do this once
            MyApi.Builder builder = new MyApi.Builder(AndroidHttp.newCompatibleTransport(),
                    new AndroidJsonFactory(), null)
                    .setRootUrl("http://10.0.2.2:8080/_ah/api/")
                    .setGoogleClientRequestInitializer(new GoogleClientRequestInitializer() {
                        @Override
                        public void initialize(AbstractGoogleClientRequest<?> abstractGoogleClientRequest) throws IOException {
                            abstractGoogleClientRequest.setDisableGZipContent(true);
                        }});
            myApiService = builder.build();}
        context = params[0].first;
        int name = params[0].second;
        try {
            return myApiService.addition(name).execute().getNo1();
           // return myApiService.addition(name).execute().getNo1();
        } catch (IOException e){
            return e.getMessage();
        }
    }

    @Override
    protected void onPostExecute(Integer result) {
        Toast.makeText(context, result, Toast.LENGTH_LONG).show();
    }
}

我想从Android端点发送一个免费的谷歌应用引擎。并希望在谷歌应用引擎页面上显示一个数字。但作为回报e.getMessage（）;我发现错误不兼容的类型

Answer 1

protected void onPostExecute(Integer result) {
    Toast.makeText(context, result, Toast.LENGTH_LONG).show();
}

（如果“结果”不是资源ID）

Toast.makeText（）将String作为第二个参数。

尝试

Toast.makeText(context, "" + result, Toast.LENGTH_LONG).show();

不兼容的类型。需要java.lang.Integer找到java.lang.String
