Question

This question is actually a 3 Part Question. Please suggest the valid solution for my problem.

Application Overview

I’m creating an application having a splash screen and a ListView. On click of the launcher icon, first the splash screen is shown and then after 3-4 seconds later, the splash screen calls the ListView activity and user is left with ListView items on the phone screen. On click of each item, respective textual content will be visible to the user. After reading the content user will click the “Back” button and will be returned to hte ListView items section again. If he/she wants to read any other item content, will be taken to that page on the click of that item. If not willing, then will click “Back” button on phone and application will close.

Part 1 – What I actually want to do

I want to show different textual content (not normal text but styled (bold/italized/containing images and all) on the click of different listView items. I can create the html pages and store them in my resource folder locally but don’t know how to call those pages while calling onItemClickListener. I’m not sure if this is a valid approach to do this sort of work or not. Please advice. It’s not working so far

Part 2 – What I’m doing instead now

Since I was not able to call the textual content so I wrote the content on some text editor, did all the fancy work on the editor and when the content was ready, I took the screenshot and then call that image instead while calling onItemClickListener. It’s working fine and I’m able to see the image on click of my ListView item.

Part 3 – The problem I’m facing

When the image is shown to the user, on click of “Back” button, the application is closed instead of going back to the ListView Section. Apparently the image opening on click of the listview item is in the same activity as is the ListView itself. What I want is that user should be able to go back to the ListView section after he/she finishes reading the textual content.

Below is the code of the ListView Activity:
public class MainActivity extends Activity {

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    ListView listView = (ListView) findViewById(R.id.menulist);
    String[] values = new String[] { "1. First Article Here", "2. Second Article Here", "3. Third Article Here"};

    ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,
        R.layout.custom_listview, R.id.text1, values);

    // Assign adapter to ListView
    listView.setAdapter(adapter);

    listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
        @Override
        public void onItemClick(AdapterView<?> parent, android.view.View view, int position, long id){
            //
            if(0==position)
            {
                setContentView(R.layout.image0); 

             }
            else if (1==position)
            {

            }
        }        

    });

}
*The code works fine upto setContentView(R.layout.image0);
* But after this I want the application to return back to the ListView section on click of “Back” button but it closes instead. Please guide.

Answer 1

May be it solves by,

Using layout.image0 in another activity and call by intent when click on list item.

By use this, When you click back button you view your previous activity
