Transfer two listview data on click of one listview

Question

In my activity I have two listviews with some data. On first listview selected row will be highlighted on click and on click on 2nd listview new activity starts. I want to send the highlighted row data of first listview and clicked row of 2nd listview data on next activity. How can Iachieve that?

Answer 1

supposing your lists are named list1 & list2, add to your list2 onItemClickListener that should looks something like this :

public void onItemClick(final AdapterView<?> parent, final View view, final int position, final long id) {
            String highlightedItem = (String)list1.getSelectedItem();
            String clickedItem = (String)list2.getItemAtPosition(position);

            Intent intent = new Intent(FirstAcivity.this, SecondActivity.class);
            intent.putExtra("highlightedItem", highlightedItem);
            intent.putExtra("clickedItem", clickedItem);

            startActivity(intent);
        }

and then in your Second Activity you can receive the items like this :

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_second);
    Intent intent = getIntent();

    if (intent != null){
        String highlightedItem = intent.getStringExtra("highlightedItem");
        String clickedItem = intent.getStringExtra("clickedItem");
    }
}

I have assumed your list items are of type String but you can apply the same logic for any other type. In case your want to send object not just primitives you need to make your objects implements Serializable or Parcelable interface.
