Java JSONArray到Listview我做错了什么？

大家好，我现在已经搜索了一段时间的错误或如何纠正错误，是的，这里的很多问题帮助我更进一步

但是我得到了一个API，其中有一个JSONArray，我想在listview中显示这些数据。到目前为止，我在我的日志中得到了我的数据，现在我只是尝试从每个对象开始显示名称（然后我可以稍后添加其余的数据），但我不确定我是否在正确的位置，也许有人可以在这里帮助我，并显示我做错了什么

非常感谢

列表视图名称：AllBirds

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

    mAuth = FirebaseAuth.getInstance();

    String URL="myAPI";

    RequestQueue requestQueue= Volley.newRequestQueue(this);


    JsonArrayRequest objectRequest = new JsonArrayRequest (Request.Method.GET, URL, null, new Response.Listener<JSONArray>() {
        @Override
        public void onResponse(JSONArray response) {
            Log.e("Rest Response",response.toString());

            try{
                for(int i=0; i<response.length();i++){
                    JSONObject jresponse = response.getJSONObject(i);
                    String NameDanish = jresponse.getString("NameDanish");

                    Log.d("NameDanish", NameDanish);


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

        }
    }, new Response.ErrorListener() {
        @Override
        public void onErrorResponse(VolleyError error) {
            Log.e("Rest Response",error.toString());
        }
    });

    requestQueue.add(objectRequest);

    ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, R.layout.activity_all_observation, NameDanish);

    ListView list = (ListView) findViewById(R.id.AllBirds);
    list.setAdapter(adapter);
}

使用以下命令更改上述代码：

        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_all_observation);

        mAuth = FirebaseAuth.getInstance();

        RequestQueue requestQueue = Volley.newRequestQueue(this);

            @Override

                Log.e("Rest Response", response.toString());

                try {
                    for (int i = 0; i < response.length(); i++) {
                        JSONObject jresponse = response.getJSONObject(i);
                        String NameDanish = jresponse.getString("NameDanish");
                        arrayList.add(NameDanish);
                        Log.d("NameDanish", NameDanish);


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

            }
        }, new Response.ErrorListener() {
            @Override
            public void onErrorResponse(VolleyError error) {
                Log.e("Rest Response", error.toString());
            }
        });

        requestQueue.add(objectRequest);

        ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, R.layout.activity_all_observation, arrayList);

        ListView list = (ListView) findViewById(R.id.AllBirds);
        list.setAdapter(adapter);
    }

对于（int i=0；i
像这样全局创建字符串arraylist

ArrayList<String> name_array=new ArrayList<>();

ArrayList name_array=new ArrayList（）；

然后加上

         try{
            for(int i=0; i<response.length();i++){
                JSONObject jresponse = response.getJSONObject(i);
                String NameDanish = jresponse.getString("NameDanish");
                name_array.add(NameDanish);
                Log.d("NameDanish", NameDanish);
            }

试试看{
对于（int i=0；i创建listView、适配器、数组作为成员变量，并使用responseHandler中的notifyDataUpdate更新数据

    ListView mList;
    ArrayAdapter<String> mAdapter
    ArrayList<String> mData;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_all_observation);
        mData=new ArrayList<>();

        mList = (ListView) findViewById(R.id.AllBirds);
        mAdapter = new ArrayAdapter<String>(this, R.layout.activity_all_observation, mData);
        list.setAdapter(adapter);

        mAuth = FirebaseAuth.getInstance();
        String URL="myAPI";

        RequestQueue requestQueue= Volley.newRequestQueue(this);


        JsonArrayRequest objectRequest = new JsonArrayRequest (Request.Method.GET, URL, null, new Response.Listener<JSONArray>() {
            @Override
            public void onResponse(JSONArray response) {
                Log.e("Rest Response",response.toString());

                try{
                    for(int i=0; i<response.length();i++){
                        JSONObject jresponse = response.getJSONObject(i);
                        String NameDanish = jresponse.getString("NameDanish");
                        mData.add(NameDanish);
                        Log.d("NameDanish", NameDanish);
                    }
                    mAdapter.notifyDataSetChanged();
                }catch(JSONException e){
                    e.printStackTrace();
                }

            }
        }, new Response.ErrorListener() {
            @Override
            public void onErrorResponse(VolleyError error) {
                Log.e("Rest Response",error.toString());
            }
        });

        requestQueue.add(objectRequest);
    }

对于（inti=0；i我现在已经将代码更改为这个，正如Toyj所说，我已经将我的xml发布到了

我没有得到任何数据，只是所有的名字都显示在日志中

    setContentView(R.layout.activity_all_observation);

    mAuth = FirebaseAuth.getInstance();
    final ArrayList arrayList = new ArrayList<>()

        @Override
        public void onResponse(JSONArray response) {
            Log.e("Rest Response",response.toString());

            try{
                //JSONArray jsonArray = new JSONArray(response);
                for(int i=0; i<response.length();i++){
                    JSONObject jresponse = response.getJSONObject(i);

什么是
NameDanish
这里您可以将JSONArray响应粘贴到json响应之前您可以传递字符串值（NameDanish）在ArrayAdapter中。请在ArrayAdapter中传递字符串数组或Arraylist。我已在底部添加了所有代码作为问题。我尝试调试på代码，但在Arraylist中未获得任何结果，但我仍能在日志中看到所有名称。很抱歉，我的评论已发布较长时间，请查看：）
