Android错误日志、清单中的活动、致命异常：AsyncTask#1

另一个安卓问题是，我试图将应用程序上的edittext中的数据发布到服务器上的脚本中，但遇到了一个又一个错误。这是我现在拥有的

        setContentView(R.layout.activity_food_search);        
        txtFoodSearch = (EditText)findViewById(R.id.txtFoodSearch);   

       // txtFoodSearch = txtFoodSearch.getText().toString();

            }

            public void onClick(View v) {

                    new MyAsyncTask().execute(txtFoodSearch.getText().toString());
                }

            }

        private class MyAsyncTask extends AsyncTask<String,  Integer, Double>{


        String fsearch = txtFoodSearch.getText().toString();

            @Override
            protected Double doInBackground(String... params) {

                postData(params[0]);
                return null;
            }

            protected void onPostExecute(Double result) {
                pb.setVisibility(View.GONE);
                Toast.makeText(getApplicationContext(), "search sent", Toast.LENGTH_LONG).show();       
            }

            protected void onProgressUpdate(Integer...progress) {
                pb.setProgress(progress[0]);
            }

            public void postData(String fsearch) {
                //create new http client
                HttpClient httpclient = new DefaultHttpClient();
                HttpPost httppost = new HttpPost("192.168.133.84/SlimandSave/try.php");

                try {
                    //add data
                    List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>();
                    nameValuePairs.add(new BasicNameValuePair("myHttpData", fsearch));
                    httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));

                    //execute HTTP post request
                    HttpResponse response = httpclient.execute(httppost);

                }   catch (ClientProtocolException e) {

                }   catch (IOException e) {

                }
            }
        }

}

编辑。。。。。以上是我的最新代码和错误日志。在php方面，我只有一个fileputcontents要写入文本文件

编辑。。。在ip地址之前添加http://似乎有效，我使用txtFoodSearch.getText（）.toString（）而不是namevalue对中的fSearch字符串。

SearchActivity

不是活动类

你有

Intent intSearch = new Intent(FoodSearchActivity.this, SearchActivity.class);
startActivity(intSearch);

它是一个异步任务类

public static class SearchActivity extends AsyncTask<String, Void, String> {

你的

doInbackground

什么都不做

您在

postData（视图v）

中有网络操作，应该进入

doInbackground

你也有

 <activity android:name="com.college.slimandsave.FoodSearchActivity$SearchActivity" >    
 </activity>

---

应该将其删除。

谢谢，基于以下内容，我想我会回到今天开始进行更改之前的状态。我已经找到了一个很好的教程，类似于我想要达到的目标，所以我将更密切地关注这一点。

public static class SearchActivity extends AsyncTask<String, Void, String> {

new SearchActivity().execute(params);

 <activity android:name="com.college.slimandsave.FoodSearchActivity$SearchActivity" >    
 </activity>
