用于自动完成视图的 TextWatcher

Question

当自动完成文本视图中添加或删除字母时，我正在尝试连续调用 json 网络服务。直到这里的一切都在这里正常工作。但是当我尝试从自动完成文本视图生成的列表中选择一个选项时，现在再次调用 Json 并且应用程序崩溃。 (ie) 自动完成中选择的值再次作为参数传递给 json get 方法，应用程序崩溃。谁能帮我解决这个问题。

companyName_autoComplete = (AutoCompleteTextView) findViewById(R.id.companyName_autoComplete);

selectIndustry_button.addTextChangedListener(new TextWatcher() {

        @Override
        public void onTextChanged(CharSequence s, int start, int before, int count) {
            // TODO Auto-generated method stub

        }

        @Override
        public void beforeTextChanged(CharSequence s, int start, int count,
                int after) {
            // TODO Auto-generated method stub

        }

        @Override
        public void afterTextChanged(Editable s) {
            // TODO Auto-generated method stub
            SearchCPS_WS();
        }
    });


private void SearchCPS_WS() {

AsyncHttpClient client = new AsyncHttpClient();
        RequestParams params = new RequestParams();

        Log.i("WebService", "WebService: "+Httppost_Links.SEARCH_COMPANY_NAME_ADD_COMPANY+textInAutoComplete+"5@0");

        client.get(Httppost_Links.SEARCH_COMPANY_NAME_ADD_COMPANY+textInAutoComplete+"/5@0", params,
                new AsyncHttpResponseHandler() {

                    @Override
                    public void onSuccess(String response) {
                        // TODO Auto-generated method stub

                        Log.i("SearchCPS_WS response: ",
                                "SearchCPS_WS response: " + response);


}

这是我的堆栈：

Answer 1

发生这种情况是因为您的网址中有空格，这部分：

Fountain Powerboat Industries, Inc.

您可以根据URI specification 将那些替换为%20。
