android - Intent 值分别形成包含多个值的 ListView 行

Question

我想将包含多个值的每个 ListView 行的值分别用于另一个 Activity 。并在另一个 Activity 中分别获取 editext 中的每个值:

我的代码是:

try
            {               
                JSONArray jArray =  new JSONArray(result);
                final ArrayList <String>arrayListTitle = new ArrayList<String>();
                    for(int i=0;i<jArray.length();i++)
                    {   
                        StringBuilder s = new StringBuilder();
                        JSONArray innerJsonArray = jArray.getJSONArray(i);
                        JSONObject json_data = innerJsonArray.getJSONObject(0);                          
                         at1=json_data.getString("title");
                         at= json_data.getString("mdate");
                         at2=json_data.getString("mtime");
                         at3=json_data.getString("venue");
                         at4=json_data.getString("organiser");
                         arrayListTitle.add(at1);
                         arrayListTitle.add(at);
                         arrayListTitle.add(at2);
                         arrayListTitle.add(at3);
                         s.append("\nTitle:"+at1);
                         s.append("\ndate:"+at);
                         s.append("\nTime:"+at2);
                         s.append("\nVenue:"+at3);
                         s.append("\nOrganiser:"+at4);  
                         s.append("\n");


                         r.add(s.toString());
                    }


                l.setAdapter(new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, r));
                l.setOnItemClickListener(new OnItemClickListener() 
                {
                    public void onItemClick(AdapterView<?> myAdapter, View myView, int myItemInt, long mylng) 
                    {
                      String selectedFromList =(String) (l.getItemAtPosition(myItemInt));

                        // Starting new intent
                        intent1 = new Intent(RequestmeetActivity.this, ConfirmmeetActivity.class);


                        intent1.putExtra("title", arrayListTitle.get(myItemInt));
                        intent1.putExtra("mdate", arrayListTitle.get(myItemInt));
                        intent1.putExtra("mtime", arrayListTitle.get(myItemInt));
                        intent1.putExtra("venue", arrayListTitle.get(myItemInt));


                        startActivity(intent1); 
                    }                 
              });
            }

我的 Activity 看起来像:

所以我想从这个 ListView 行中单独获取值，并将这些值用于另一个 Activity 。我怎样才能做到这一点。请帮助我，我是 android 的新手。提前致谢。在另一个 Activity 上

Bundle extras = getIntent().getExtras();
    if(extras != null){ 
      mtitle = extras.getString("title");
      stime = extras.getString("mtime");
      sdate = extras.getString("mdate");
      cvenue = extras.getString("venue");
    }

    title.setText(mtitle);
    cdate=(EditText)findViewById(R.id.editText2);
    cdate.setText(sdate);
    venue=(EditText)findViewById(R.id.editText4);
    venue.setText(cvenue);
    ctime=(EditText)findViewById(R.id.editText3);
    ctime.setText(stime);

Answer 1

defind global ArrayList arrayListTitle = new ArrayList;正如您在 r 中定义的那样。并在 for 循环中附加代码之前在其中添加值。对于标题 arrayListTitle.add(at1);

ArrayList<String> arrayListTitle = new ArrayList<String>;

    for(int i=0;i<jArray.length();i++) {    
            StringBuilder s = new StringBuilder();
            JSONArray innerJsonArray = jArray.getJSONArray(i);
            JSONObject json_data = innerJsonArray.getJSONObject(0);
            at1=json_data.getString("title");
            at= json_data.getString("mdate");
            at2=json_data.getString("mtime");
            at3=json_data.getString("venue");
            at4=json_data.getString("organiser");
            arrayListTitle.add(at1);  // check this line I have added value of title in arraylist you can take it same as data and time etc.
            s.append("\nTitle:"+at1);
            s.append("\ndate:"+at);
            s.append("\nTime:"+at2);
            s.append("\nVenue:"+at3);
            s.append("\nOrganiser:"+at4);   
            s.append("\n");
            r.add(s.toString());
        }

对于 ListView 项目点击:

 l.setOnItemClickListener(new OnItemClickListener() {
    public void onItemClick(AdapterView<?> myAdapter, 
                                   View myView, int myItemInt, long mylng) {
        String selectedFromList =(String) (l.getItemAtPosition(myItemInt));
        // Starting new intent
        intent1 = new Intent(RequestmeetActivity.this, 
                                                    ConfirmmeetActivity.class);
        intent1.putExtra("title",arrayListTitle.get(myItemInt)); // check this line get value from the arraylistTitle for the particular position.
        intent1.putExtra("mdate",selectedFromList);
        intent1.putExtra("uid",uid);
        startActivity(intent1); 
    }

在另一个 Activity 中获取标题时:编写如下代码:

String title;

Bundle extras = getIntent().getExtras();
if(extras != null){ 
  title = extras.getString("title"); // same for others
}

editTxt.setText(title);
