    <p>May I ask you to guide me how I can accomplish this problem? I need to compare an inputWord to a string inside a .txt file and if found, return the whole line but if not, show "word not found".</p> <p>Example:</p> <pre><code>inputWord: abacus Text file content: abaca - n. large herbaceous Asian plant of the banana family. aback - adv. archaic towards or situated to the rear. abacus - n. a frame with rows of wires or grooves along which beads are slid, used for calculating. ... so on Returns: abacus with its definition </code></pre> <p>What i am trying to do is compare my inputWord to the words before the " - " (hyphen as delimiter), if they dont match, move to the next line. If they match, copy the whole line.</p> <p>I hope it doesnt seem like im asking you to "do my homework" but I tried tutorials around different forums and sites. I also read java docs but i really cannot put them together to accomplish this.</p> <p>Thank you in advance!</p> <p>UPDATE:</p> <p>Here's my current code:</p> <pre><code>if(enhancedStem.startsWith("a")) { InputStream inputStream = getResources().openRawResource(R.raw.definitiona); try { BufferedReader in = new BufferedReader(new InputStreamReader(inputStream)); String s = in.readLine(); String delimiter = " - "; String del[]; while(s != null) { s = in.readLine(); del = s.split(delimiter); if (enhancedStem.equals(del[0])) { in.close(); databaseOutput.setText(s); break; } } in.close(); } catch (FileNotFoundException e) { databaseOutput.setText("" + e); } catch (IOException e1) { databaseOutput.setText("" + e1); } } </code></pre> <p>Thanks a lot! Here's what I came up, and it returns the definition of inputs properly but the problem is, when i enter a word not found in the textfile, the app crashes. The catch phrase doesn't seem to work. Have any idea how I can trap it? Logcat says NullPointerExcepetion at line 4342 which is</p> <pre><code>s = in.readLine(); </code></pre>

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.
