copied!<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>
