      adapter = new CustomAdapter(CustomListView, stu, res); 
      studentlist.setAdapter((ListAdapter) adapter); 
     } 

Answer 1

我正在做，

使用光标

光标C = db.rawQuery（”从本次活动发送意图另一个活动SELECT * FROM student“，null）;

    if (c.getCount() == 0) { 
         showMessage("No records found"); 
         return; 
        } 

       // convert array list to string 

       List<String> buffer = new ArrayList<String>(); 

        while (c.moveToNext()) 
         { 

          buffer.add("" + c.getString(1)+ " "+ c.getString(2)); 

         } 

          Intent intent = new Intent(this, viewdetails.class); 
          intent.putStringArrayListExtra(EXTRA_MESSAGE, (ArrayList<String>) buffer); 
          startActivity(intent); 
      } 

在另一个列表活动

Intent intent=getIntent(); 

    ArrayList<String> buffer = intent.getStringArrayListExtra(MainActivity.EXTRA_MESSAGE); 
    ListView lListView = new ListView(this); 
    lListView = (ListView)findViewById(R.id.content); 

    ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,android.R.layout.simple_list_item_1,buffer); 

    lListView.setAdapter(adapter);
