Here is my question: When I clock on element from the list a new activity starts, where I have one ListView and two TextBoxes. How I can do this if I click first element in the new activity in ListView will be ListViewfrom this item and in TextBoxeswill be data from TextBoxes from the list.

Answer 1

You can pass extras to the Intent you use when starting the new Activity.

Let’s say your current activity is MyActivity, and the one you want to start by clicking on a list item is MyNewActivity; Then in your MyActivity class, inside the list item click listener should be modified as:

Intent intent = new Intent(MyActivity.this, MyNewActivity.class);
intent.putExtra("my.picture.id", images[itemPosition]);
intent.putExtra("my.header.id", headers[itemPosition]);
intent.putExtra("my.text.id", texts[itemPosition]);
startActivity(intent);

and in your MyNewActivity class’ onCreate method you are able to retrieve the passed extras, and fill the proper fields with the correct values:

final Intent intent = getIntent();
final int pictureId = intent.getIntExtra("my.picture.id", 0);
final int headerId = intent.getIntExtra("my.header.id", 0);
final int textId = intent.getIntExtra("my.text.id", 0);

((ImageView)findViewById(R.id.my_image)).setImageResource(pictureId);
((TextView)findViewById(R.id.my_header)).setText(headerId);
((TextView)findViewById(R.id.my_text)).setImageResource(textId);

the images, headers and texts arrays -I suppose- contain the resource ids for the images and strings you want to display. They are probably accessible via the data of your current item’s renderer.
