Try to use Custom view for List row and implement that view into List View.

Here are some of the links for Custom List

You could try saving the array list to Internal Storage as a file. Check this answer or code below,

For writing to file,

    try {
   //Modes: MODE_PRIVATE, MODE_WORLD_READABLE, MODE_WORLD_WRITABLE
   FileOutputStream output = openFileOutput("lines.txt",MODE_WORLD_READABLE);
   DataOutputStream dout = new DataOutputStream(output);
   dout.writeInt(text_lines.size()); // Save line count
   for(String line : text_lines) // Save lines
      dout.writeUTF(line);
   dout.flush(); // Flush stream ...
   dout.close(); // ... and close.
}
catch (IOException exc) { exc.printStackTrace(); }

For reading it,

    FileInputStream input = openFileInput("lines.txt"); // Open input stream
DataInputStream din = new DataInputStream(input);
int sz = din.readInt(); // Read line count
for (int i=0;i<sz;i++) { // Read lines
   String line = din.readUTF();
   text_lines.add(line);
}
din.close();
