    <p>When I click the button (btnPrintTardy) I need to generate a .txt file of whatever i have entered into a txtbox (editText1).</p> <p>This is my File Writer java class.</p> <pre><code>import android.app.Activity; import java.io.*; import android.os.Bundle; import android.view.*; import android.widget.*; public class FileWriter extends Activity { EditText txtData; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); txtData = (EditText) findViewById(R.id.editText1); } public void onClick(View v) { // write in data folder try { File myFile = new File("/data/LatePass/StudentLatePass.txt"); myFile.createNewFile(); FileOutputStream fOut = new FileOutputStream(myFile); OutputStreamWriter myOutWriter = new OutputStreamWriter(fOut); myOutWriter.append(txtData.getText()); myOutWriter.close(); fOut.close(); Toast.makeText(getBaseContext(), "Finished writing StudentLatePass.txt'", Toast.LENGTH_SHORT).show(); } catch (Exception e) { Toast.makeText(getBaseContext(), e.getMessage(), Toast.LENGTH_SHORT).show(); } finish(); }; } </code></pre> <p>I am calling this method from my "StudentActivity" however, this is where i am kind of stuck. I want to stay on my current screen activity, but run the filewriter in the background. So how would I call this? </p> <p>I have tried</p> <pre><code> public void UpdateStudenttxtfile(View View) { Intent intent = new Intent(View.getContext(), FileWriter.class); intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP); } </code></pre> <p>with no luck :(</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.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
