在尝试将我的 JSON 信息解析为 ListView 时，我不断收到以下错误。

上面的 Logcat 声明错误是我的 StandingsAdapter 类的第 65 行，它在下面。第 66 行是 standingsHolder.txt_id.setText( standings.getTeam_id() );

public class StandingsAdapter extends ArrayAdapter {
    List list = new ArrayList();
    public StandingsAdapter(@NonNull Context context, @LayoutRes int resource) {
        super( context, resource );
    }

    public void add(Standings object) {
        super.add( object );
        list.add( object );
    }

    @Override
    public int getCount() {
        return list.size();
    }

    @Nullable
    @Override
    public Object getItem(int position) {
        return list.get( position );
    }

    @NonNull
    @Override
    public View getView(int position, @Nullable View convertView, @NonNull ViewGroup parent) {
        View row;
        row = convertView;
        StandingsHolder standingsHolder;
        if(row ==null){
            LayoutInflater layoutInflater= (LayoutInflater) this.getContext().getSystemService( Context.LAYOUT_INFLATER_SERVICE );
            row = layoutInflater.inflate(R.layout.row_layout, parent, false);
            standingsHolder = new StandingsHolder();
            standingsHolder.tx_id = (TextView) row.findViewById( R.id.sec_1 );
            standingsHolder.txt_id = (TextView) row.findViewById( R.id.sec_2 );
            standingsHolder.tx_fn = (TextView) row.findViewById( R.id.sec_3 );
            standingsHolder.tx_ln = (TextView) row.findViewById( R.id.sec_4 );
            standingsHolder.tx_pos = (TextView) row.findViewById( R.id.sec_5 );
            standingsHolder.tx_po = (TextView) row.findViewById( R.id.sec_6 );
            row.setTag( standingsHolder );
        }
        else
        {
            standingsHolder = (StandingsHolder) row.getTag();
        }
        Standings standings = (Standings)this.getItem( position );
        standingsHolder.tx_id.setText( standings.getDriver_id() );
        standingsHolder.txt_id.setText( standings.getTeam_id() );
        standingsHolder.tx_fn.setText( standings.getFirstName() );
        standingsHolder.tx_ln.setText( standings.getLastName() );
        standingsHolder.tx_pos.setText( standings.getPosition() );
        standingsHolder.tx_po.setText( standings.getPoints() );

        return row;
    }

    static class StandingsHolder {
        TextView tx_id, txt_id, tx_fn, tx_ln, tx_pos, tx_po;
    }
}

我将发布我的 android 应用程序中涉及此错误的其他类。下面是我的 Standings 类

public class Standings {
    private int driver_id;
    private int team_id;
    private String firstName;
    private String lastName;
    private int position;
    private int points;


    public Standings(int driver_id, int team_id, String  firstName, String lastName, int position, int points) {

        this.setDriver_id( driver_id );
        this.setTeam_id( team_id );
        this.setFirstName( firstName );
        this.setLastName( lastName );
        this.setPosition( position );
        this.setPoints( points );

    }

    public int getDriver_id() {
        return driver_id;
    }

    public void setDriver_id(int driver_id) {
        this.driver_id = driver_id;
    }

    public int getTeam_id() {
        return team_id;
    }

    public void setTeam_id(int team_id) {
        this.team_id = team_id;
    }

    public String getFirstName() {
        return firstName;
    }

    public void setFirstName(String firstName) {
        this.firstName = firstName;
    }

    public String getLastName() {
        return lastName;
    }

    public void setLastName(String lastName) {
        this.lastName = lastName;
    }

    public int getPosition() {
        return position;
    }

    public void setPosition(int position) {
        this.position = position;
    }

    public int getPoints() {
        return points;
    }

    public void setPoints(int points) {
        this.points = points;
    }
}

下面是我的 StandingList fragment ，它是 Main Fragment，其中包含用于下载 JSON 和解析 JSON< 的按钮 找到了。

public class StandingsList extends Fragment implements View.OnClickListener {
    //make member variable is Views
    Button mButton;
    Button mButton1;
    TextView mResult;
    String JSON_RESPONSE;
    String json_string;

    ProgressDialog mProgressDialog;


    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
        // Inflate the layout for this fragment
        View view = inflater.inflate( R.layout.fragment_standings, container, false );


        //get reference of the views
        mButton = (Button) view.findViewById( R.id.button );
        mButton1 = (Button) view.findViewById( R.id.buttontwo );
        mResult = (TextView) view.findViewById( R.id.result );
        mButton1.setOnClickListener(this);

        //when button is clicked
        mButton.setOnClickListener( new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                //call the getJsonResponse method and fetch the response from the server
                new getJsonResponse().execute();
            }
        } );

        return view;
    }


        public class getJsonResponse extends AsyncTask<Void, Void, String> {
            String serverUrl;

            public getJsonResponse() {
                mProgressDialog = new ProgressDialog( getActivity() );
                mProgressDialog.setMessage( "Please Wait" );
                mProgressDialog.setTitle( "Processing" );
                mProgressDialog.setCancelable( false );
            }

            @Override
            protected void onPreExecute() {

                //set the url from we have to fetch the json response
                serverUrl = "http://163.172.142.145/get_info.php";
                mProgressDialog.show();
            }

            @Override
            protected String doInBackground(Void... params) {
                try {
                    URL url = new URL( serverUrl );
                    HttpURLConnection httpURLConnection = (HttpURLConnection) url.openConnection();
                    InputStream inputStream = httpURLConnection.getInputStream();
                    BufferedReader bufferedReader = new BufferedReader( new InputStreamReader( inputStream ) );
                    StringBuilder stringBuilder = new StringBuilder();

                    while ((JSON_RESPONSE = bufferedReader.readLine()) != null) {

                        stringBuilder.append( JSON_RESPONSE + "\n" );

                    }

                    inputStream.close();
                    bufferedReader.close();
                    httpURLConnection.disconnect();

                    return stringBuilder.toString().trim();

                } catch (MalformedURLException e) {
                    Log.e( TAG, "MalformedURLException: " + e ); //print exception message to log
                } catch (IOException e) {
                    Log.e( TAG, "IOException: " + e ); //print exception message to log
                }
                return null;
            }

            @Override
            protected void onProgressUpdate(Void... values) {
                super.onProgressUpdate( values );
            }

            @Override
            protected void onPostExecute(String result) {
                //set the result which is returned by doInBackground() method to result textView
                mResult.setText( result );
                mProgressDialog.dismiss();
                json_string = result;
            }

        }

            public void onClick(View view){

                switch (view.getId()) {
                    case R.id.buttontwo:

                        Intent intent = new Intent(getActivity(), DisplayListView.class);
                        intent.putExtra( "json_data",json_string );
                        startActivity( intent );


                        break;

                }


            }
        }

我拥有的最后一个 class 与 JSON Parse 一起工作的是 Display in List View 类，这意味着它的名字是什么。下面是:

public class DisplayListView extends AppCompatActivity {

    String json_string;
    JSONObject jsonObject;
    JSONArray jsonArray;
    StandingsAdapter standingsAdapter;
    ListView listView;


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate( savedInstanceState );
        setContentView( R.layout.display_list_view_layout );
        listView= (ListView) findViewById( R.id.ListViewParse );
        standingsAdapter = new StandingsAdapter(this,R.layout.row_layout);
        listView.setAdapter( standingsAdapter );
        json_string = getIntent().getExtras().getString( "json_data" );
        try {
            jsonArray  = new JSONObject(json_string).getJSONArray("server_response");


            int count = 0;

            int driver_id, team_id, position, points;
            String firstName, lastName;



            while(count<jsonArray.length())
            {
                JSONObject JO = jsonArray.getJSONObject(count);
                driver_id = JO.getInt( "Driver_id" );
                team_id =JO.getInt( "Team_id" );
                firstName = JO.getString( "First_name" );
                lastName= JO.getString( "Last_name" );
                position= JO.getInt( "Position" );
                points = JO.getInt( "Points" );

                Standings standings = new Standings(driver_id, team_id, firstName, lastName, position, points );
                standingsAdapter.add( standings );
                count++;
            }

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

    }
}
