Android 将单击位置的JSON数据发送到另一个活动

我的活动中有一个RecyclerView，我从服务器的JSON数据填充它。但我想将单击位置的数据发送到另一个活动，然后我可以编辑它们并将它们发送回服务器。但当我将数据发送到另一个活动时，所有JSON数组都会发送到另一个活动，并创建下一个活动的几个实例。下面是我的包含RecyclerView的活动：

public class ActivityAllUsers extends AppCompatActivity {

List<GetDataAdapter> GetDataAdapter1;

RecyclerView recyclerView;

RecyclerView.LayoutManager recyclerViewlayoutManager;

RecyclerView.Adapter recyclerViewadapter;

ProgressBar progressBar;

String GET_JSON_DATA_HTTP_URL = "http://shayea.tk/sof/get_allusers.php";
String JSON_USERNAME = "usr_name";
String JSON_EMAIL = "usr_email";
String JSON_PHONE = "usr_phone";
String JSON_ORG = "org_name";
String JSON_STATUS ="usr_status";
String JSON_USRTYPE ="prv_name";

JsonArrayRequest jsonArrayRequest ;

RequestQueue requestQueue ;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_all_users);
    GetDataAdapter1 = new ArrayList<>();
    recyclerView = (RecyclerView) findViewById(R.id.recyclerView1);
    progressBar = (ProgressBar) findViewById(R.id.progressBar1);
    recyclerView.setHasFixedSize(true);
    recyclerViewlayoutManager = new LinearLayoutManager(this);
    recyclerView.setLayoutManager(recyclerViewlayoutManager);
    JSON_DATA_WEB_CALL();
    progressBar.setVisibility(View.VISIBLE);




}

public void JSON_DATA_WEB_CALL(){

    jsonArrayRequest = new JsonArrayRequest(GET_JSON_DATA_HTTP_URL,

            new Response.Listener<JSONArray>() {
                @Override
                public void onResponse(JSONArray response) {

                    progressBar.setVisibility(View.GONE);

                    JSON_PARSE_DATA_AFTER_WEBCALL(response);
                }
            },
            new Response.ErrorListener() {
                @Override
                public void onErrorResponse(VolleyError error) {

                }
            });

    requestQueue = Volley.newRequestQueue(this);

    requestQueue.add(jsonArrayRequest);
}

public void JSON_PARSE_DATA_AFTER_WEBCALL(final JSONArray array){

    for(int i = 0; i<array.length(); i++) {

        final GetDataAdapter GetDataAdapter2 = new GetDataAdapter();

        JSONObject json = null;
        try {
            json = array.getJSONObject(i);

            GetDataAdapter2.setusername(json.getString(JSON_USERNAME));

            GetDataAdapter2.setEmail(json.getString(JSON_EMAIL));

            GetDataAdapter2.setPhone_number(json.getString(JSON_PHONE));

            GetDataAdapter2.setPrivilege(json.getString(JSON_USRTYPE));

            GetDataAdapter2.setOrganization(json.getString(JSON_ORG));

            GetDataAdapter2.setStatus(json.getString(JSON_STATUS));

            Log.e("JSON ME :" , json.toString());

            final String username = (json.getString(JSON_USERNAME));
            final String email = (json.getString(JSON_USERNAME));
            final String phone = (json.getString(JSON_USERNAME));
            final String usertype = (json.getString(JSON_USERNAME));

            recyclerView.addOnItemTouchListener(
                    new RecyclerTouchListener(getApplicationContext(), recyclerView,
                            new RecyclerTouchListener.OnTouchActionListener() {
                                @Override
                                public void onClick(View view, int position) {

                                    Intent intent = new Intent(ActivityAllUsers.this,RegisterNewCompany.class);
                                    intent.putExtra("username" , username);
                                    intent.putExtra("email" , email);
                                    intent.putExtra("phone" , phone);
                                    intent.putExtra("usertype" , usertype);
                                    startActivity(intent);

                                }
                                @Override
                                public void onRightSwipe(View view, int position) {
                                }
                                @Override
                                public void onLeftSwipe(View view, int position) {
                                }
                            }));

        } catch (JSONException e) {

            e.printStackTrace();
        }
        GetDataAdapter1.add(GetDataAdapter2);
    }

    recyclerViewadapter = new RecyclerViewAdapter(GetDataAdapter1, this);

    recyclerView.setAdapter(recyclerViewadapter);
}
}

我已经检查了这类主题的大多数问题，但是它们的实现是不同的。

任何帮助都将不胜感激

我可以看到您正在为for循环的每个迭代添加一个触控监听器<代码>recyclerView.addOnItemTouchListener

您应该确保只执行一次

recyclerView.addonimtouchlistener

。使用

onClick

方法中的

int-position

参数获取被触摸/单击的项目

例如：

单击editem=array.getJSONObject（位置）；

发生的情况是：

如果数组长度为10，则将10个itemTouchListeners添加到回收器视图中。这意味着在touch上，所有10个侦听器都按照您添加它们的顺序被调用。因此，解释了下一个活动的几个实例。此外，每个侦听器都使用不同的项调用它-因此看起来所有json都被传递了。启动活动时，可以传递一些标志，以确保一次只存在一个实例。花些时间来

我将

recyclerView.AddonimtouchListener

移出循环，现在它没有打开活动的多个实例，但我无法通过此代码将数据发送到其他活动

clickedItem=array.getJSONObject（位置）你能给我一点指导或编辑点击某个项目的代码吗
public class RecyclerViewAdapter extends RecyclerView.Adapter<RecyclerViewAdapter.ViewHolder> {

Context context;

List<GetDataAdapter> getDataAdapter;

public RecyclerViewAdapter(List<GetDataAdapter> getDataAdapter, Context context){
