Question

我想创建一个用户输入手机号码的应用，然后点击用户手机号码发送到服务器URL的继续按钮。这是我的代码

MainActivity.java

public class MainActivity extends Activity {

    private static final String TAG = "Http Connection";
    private EditText mobileno;
    private Button proceed;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.mobilenumber);

        mobileno = (EditText) findViewById(R.id.editText);
        proceed = (Button) findViewById(R.id.button);
        proceed.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                AsyncHttpTask asyncHttpTask = new AsyncHttpTask();
                final String url = "http://javatechig.com/api/get_category_posts/?dev=1&slug=android";
                String MobileNo = mobileno.getText().toString();
                new AsyncHttpTask().execute(url);
            }
        });

    }


    public class AsyncHttpTask extends AsyncTask<String, Void, Integer> {
        private ProgressDialog pDialog;

        @Override
        protected void onPreExecute() {
            super.onPreExecute();
            pDialog = new ProgressDialog(MainActivity.this);
            pDialog.setMessage("Attempting Proceed..");
            pDialog.setIndeterminate(false);
            pDialog.setCancelable(true);
            pDialog.show();
            pDialog.dismiss();
        }
        @Override
        protected Integer doInBackground(String... params) {

            InputStream inputStream = null;

            HttpURLConnection urlConnection = null;

            Integer result = 0;
            try {
                /* forming th java.net.URL object */
                URL url = new URL(params[0]);
                String mobileNo = mobileno.getText().toString();
                urlConnection = (HttpURLConnection) url.openConnection();

                 /* optional request header */
                urlConnection.setRequestProperty("Content-Type", "application/json");

                /* optional request header */
                urlConnection.setRequestProperty("Accept", "application/json");

                /* for Get request */
                urlConnection.setRequestMethod("GET");

                int statusCode = urlConnection.getResponseCode();

                /* 200 represents HTTP OK */
                if (statusCode ==  200) {

                    inputStream = new BufferedInputStream(urlConnection.getInputStream());

                    String response = convertInputStreamToString(inputStream);

                    parseResult(response);

                    result = 1; // Successful

                }else{
                    result = 0; //"Failed to fetch data!";
                }

            } catch (Exception e) {
                Log.d(TAG, e.getLocalizedMessage());
            }

            return result; //"Failed to fetch data!";
        }


        @Override
        protected void onPostExecute(Integer result) {


            if(result == 1){

                Toast.makeText(MainActivity.this,result, Toast.LENGTH_LONG).show();
            }else{
                Log.e(TAG, "Failed to fetch data!");
            }
        }
    }


    private String convertInputStreamToString(InputStream inputStream) throws IOException {

        BufferedReader bufferedReader = new BufferedReader( new InputStreamReader(inputStream));

        String line ;
        String result=null ;

        while((line = bufferedReader.readLine()) != null){
            result += line;
        }

            /* Close Stream */
        if(null!=inputStream){
            inputStream.close();
        }

        return result;
    }
    private void parseResult(String result) {

        try{
            JSONObject response = new JSONObject(result);

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

这是我的xml文件：

Answer 1

在服务器调用时，您没有通过MobileNo。

要这样做，

String MobileNo = mobileno.getText().toString();

final String url = "http://javatechig.com/api/get_category_posts/?dev=1&slug=android&mobile_no=" + MobileNo ;

将mobile_no替换为相应的参数名称。

将点击按钮上的手机号码发送到Android中的服务器URL
