text: Q:
  
  add data to listview from edittext another activity android
  
  i want to ask..
  i have 2 activity, just say  form1 and form2, and i have a listview on form1. i want to add data from edittext in form2 with a button into listview in form 1..how can i do that?
  if i use onResume() the user must change activity to form1 to get the listview refreshed..
  i try to use this code but its seems didnt work..
  if(form1.listviewname != null)
  {
          ((ArrayAdapter)form1.listviewname.getAdapter()).notifyDataSetInvalidated();
  }
  
  thank you!!
  ------------------------------------------------------------edited----------
  just now i tried to use this code on form2
  list_list.add(myitem);
  form1.listview.setAdapter(adapter1);                        
  adapter1.notifyDataSetChanged();
  
  myitem is string which get the value from textbox in form 2
  its seems work but now the problem is everytime i add the data to listview in form1 its always overwrite the existing data in listview..
  how can i fix this?
  thank you!!
  RESOLVED---------------------------------------------------
  resolved by declaring this on form2
  public static ArrayList<String> list_list = new ArrayList<String>(); 
  
  public static ArrayAdapter<String> adapter1;
  
  i added public static.
  thank you!!!
  
  A:
  
  - Suppose Activity A has the ListView and Activity B has the EditText with Button.
  In Activity B :
  Button mbutt = (Button)findViewById(R.id.button_mSubmit);
  EditText mtext = (EditText)findViewById(R.id.editText_mData);
  
  mbutt.setOnClickListener(new OnClickListener(){
  
     public void onClick(View v) {
  
                        Intent i = new Intent(B.this, A.class);
  
                        i.putExtra("text_key",mtext.getText().toString());
  
                        startActivity(i);
          }
  
  });
  
  In Activity A :
  - Here in onResume(), do this
   Intent i = getIntent();
  
   String mdata = i.getExtras().getString("text_key");
  
  - Now you have got the data in mdata variable, i hope you have used a static ArrayList in Activity A, to hold the data which in turn has to be fed into the ArrayAdater.
  Eg:
  public static ArrayList<String> aList = new ArrayList<String>();
  
  - Now finally in the onResume(), you have to add this mdata variable's value into ArrayList and then fed it into the ArrayAdpater and then again set the ListView with this Adapter.
