Declare newclass in file AndroidManifest.

<activity

Xml file of newclass like this.

The  <ImageSwitcher make backgroind image fit with screen.

If use LinearLayout and set background image, it look not like original picture. You can try to see.

In class new, declare 3 textView tv, tv2, tv3.

Remove status bar and keep screen on.

Create a String array contain names of author.

String[] tacgia = { "Teika","Jakuren", "Narihita", "Komachi", "Saigyo", "Teika", "Shikibu", "Teika" };

Create an Object like this.

Object[]mang={R.raw.t1,R.raw.t2,R.raw.t3,R.raw.t4,R.raw.t5,R.raw.t6,R.raw.t7,R.raw.t8};

Object like array, but we can put in uit anything, here is address of poems.

Copy these lines to class new.

Intent in = getIntent();

Bundle bun = in.getExtras();       

int vitri = bun.getInt("gi");

String tenbai = bun.getString("gi2");

tv.setText(tenbai);

tv.setTypeface(Typeface.MONOSPACE, Typeface.BOLD);

tv3.setText(tacgia[vitri]);

We use InputStream to read txt file, set to textView tv2.

InputStream inp = this.getResources().openRawResource((Integer) mang[vitri]);

     try

    {

    byte[] buffer = new byte[inp.available()];

        while (inp.read(buffer) != -1);

        String jsontext = new String(buffer);

        tv2.setText(jsontext);       

      

    } 

    catch (IOException e)

    {

        //return null;

    }

See the line openRawResource((Integer) mang[vitri]); it access address of poem in Object mang.

Code look like this.

Run to see this result.
