Question

我想将列表项上的正确json对象单击第一个活动中的第二个活动。如果我单击任何列表项，则JSONArray响应中的json对象应该传递给intent，我的下一个活动必须得到它。这是我的代码

JsonArrayRequest postReq = new JsonArrayRequest(url,
                new Response.Listener<JSONArray>() {
                    @Override
                    public void onResponse(JSONArray response) {
                        Log.d(TAG, response.toString());
                        hidePDialog();

                        // Parsing json
                        for (int i = 0; i < response.length(); i++) {
                            try {

                                JSONObject obj = response.getJSONObject(i);
                                Consumer user = new Consumer();
                                user.setTitle(obj.getString("name"));
                                user.setUserid(obj.getString("user"));
                                user.setThumbnailUrl(obj.getString("image"));
                                user.setAmountreq(obj.getString("price"));
                                user.setTime(obj.getString("date"));
                                user.setCounty(obj.getString("county"));

                                // adding request to consumer class
                                userList.add(user);

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

                        }

                         /*notifying list adapter about data changes
                         so that it renders the list view with updated data*/
                        adapter.notifyDataSetChanged();
                    }
                }, new Response.ErrorListener() {
                    @Override
                    public void onErrorResponse(VolleyError error) {
                        VolleyLog.d(TAG, "Error: " + error.getMessage());
                        hidePDialog();

                    }
                });

        // Adding request to request queue
        AppController.getInstance().addToRequestQueue(postReq);
        // listening to single list item on click
           listView.setOnItemClickListener(new OnItemClickListener() {
              public void onItemClick(AdapterView<?> parent, View view, int position, long id) {



                  if(!obj.isNull(position)){
                    //start new activity
                      Intent myIntent = new Intent(RequestFeedActivity.this,RequestFeed.class);  
                      myIntent.putExtra("name", obj.getJSONObject(position).toString());
                      startActivity(myIntent);                                     
                    }   

                      // ListView Clicked





              }
            });
    }

这里的其他活动是我想要传递的变量的示例代码

TextView rname, rtitle,rprice, rdate, rdesc, rcounty;
@Override
protected void onCreate(Bundle savedInstanceState){
    super.onCreate(savedInstanceState);
    setContentView(R.layout.requestfeed);

    rtitle = (TextView)findViewById(R.id.IDRproduct);
    rprice = (TextView)findViewById(R.id.IDRquote);
    rdate = (TextView)findViewById(R.id.IDRdate);
    rdesc = (TextView)findViewById(R.id.IDRdesc);
    rname = (TextView)findViewById(R.id.IDRname);

     Intent myIntent = getIntent();
    //Assign values
    rname.setText(myIntent.getExtras().getString("name")); 
    rtitle.setText(myIntent.getExtras().getString("title"));
    rprice.setText(myIntent.getExtras().getString("pricetag"));
    rdate.setText(myIntent.getExtras().getString("timereq"));
    rdesc.setText(myIntent.getExtras().getString("description"));
    rcounty.setText(myIntent.getExtras().getString("county")); 




}

我试过这个answer但是没有用。很多人非常感谢

Answer 1

试试这个

Intent i =new Intent(this,ActivityA.class);
Bundle b =new Bundle();
i.putExtra("KEY","VALUE");
i.putExtras(b);
startActivity(i)

在接收方

Bundle b=getIntent().getExtras();
b.getInt("KEY") //useaccording to ur need

如果不起作用，请检查此answer

Answer 2

尝试替换代码的和平：

myIntent.getExtras().getString("name")

使用此代码：

myIntent.getStringExtra("name");

Android将JSON对象的值传递给列表项单击上的另一个活动
