Question

i have a xml parser with lazy adapter, i parse all the data to an list view.

now i would like to grabe all the data from the listivew(wiche is 1 textview per row) and put is in and string array
but i have no idea how i have to do that. because if i Google i only get results on how to use and string array to populate the list.

my parser:

TextView txt =(TextView)vi.findViewById(R.id.tv);
HashMap<String, String> song = new HashMap<String, String>();
song = data.get(position);     
txt.setText(song.get(MainActivity.KEY_TXT));

the method i use (so far) for getting my string array:

private String[] txt = {

}

thanks in advance.

Answer 1

You just have to use the string array in getView() method of listView adapter. like this:–

give the size of strArray same as the size of listView.

String strArray[] = new String[<size of Your ListView>]; 

@Override
public View getView(int position, View convertView, ViewGroup parent) {


    TextView textView;
    if (convertView == null) {

        convertView = inflater.inflate(R.layout.listitem, parent, false);
        textView = (TextView) convertView
                .findViewById(R.id.textView);
    }
    strArray[position] = textView.getText().toString();
    return convertView;
}

now u want to use this strArray to other class then either you have to make it static or you could pass this to other class via intent.like this:–

Bundle b=new Bundle();
b.putStringArray(key, new String[]{value1, value2});
Intent i=new Intent(context, Class);
i.putExtras(b);

and then in other activity class You should get this String array by putting this code:–

Bundle b=this.getIntent().getExtras();
String[] array=b.getStringArray(key);

and if the class to whom you want to pass the String Array( that is strArray) is not Activity then You should make your strArray static like this:

public static strArray[];

now i think your problem will be solved..
