    <p>This is my first time on here, so I'm bit nervous and please forgive me if I don't seem entirely clear about what I'm asking. </p> <p>The problem is, Im trying to read in a file from a subfolder in the assets folder, using a method that I've created in a separate class. I've researched this for a couple of days but I'm unable to find the solution anywhere, so I've come here as a last resort. I needed the file reading method to be separate as there are other views/activities that will be utilising exactly the same method and I don't think it would be wise to keep copying and pasting the same code for each activity. Ok here's what I've done so far: </p> <pre><code>public class ReadAssets extends Activity { public void read(Context context, String filepath, int textviewid) { try { InputStream input = getAssets().open(filepath); int size = input.available(); // Read the entire asset into a local byte buffer. byte[] buffer = new byte[size]; input.read(buffer); input.close(); // Convert the buffer into a string. String text = new String(buffer); // Finally insert the string into the text view. TextView tv = (TextView) findViewById(textviewid); tv.setText(text); } catch (IOException e) { // Throws an exception if an error is found throw new RuntimeException(e); } } } </code></pre> <p>The activity that I would like to place this method in: </p> <pre><code>public class GeneralSetupActivity extends Activity { @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.gettingstarted_layout); ReadAssets nA = new ReadAssets(); nA.read(this,"gettingstarted/GettingStarted.txt", R.id.displayTextView); // try { // InputStream input =getAssets().open("gettingstarted/GettingStarted.txt"); // // int size = input.available(); // // // Read the entire asset into a local byte buffer. // byte[] buffer = new byte[size]; // input.read(buffer); // input.close(); // // // Convert the buffer into a string. // String text = new String(buffer); // // // Finally insert the string into the text view. // TextView tv = (TextView) findViewById(R.id.displayTextView); // tv.setText(text); // // } catch (IOException e) { // // Throws an exception if an error is found // throw new RuntimeException(e); // } } } </code></pre> <p>I'd really appreciate it file someone could point me towards the right direction. And also I hope I'm not taking advantage but I'd like to know how I'd import and display a series of text files, one after another. </p> <p>Cheers Guys, Thanks :)</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
