copied!<p>You can use AsyncTask and set new TextView in every onProgressUpdate:</p> <pre><code>protected class InitTask extends AsyncTask<Context, Integer, String> { // -- run intensive processes here // -- notice that the datatype of the first param in the class definition matches the param passed to this method // -- and that the datatype of the last param in the class definition matches the return type of this method @Override protected String doInBackground( Context... params ) { //-- on every iteration //-- runs a while loop that causes the thread to sleep for 2 minutes //-- publishes the progress - calls the onProgressUpdate handler defined below //-- and increments the counter variable i by one int i = 0; while( i <= 50 ) { try{ Thread.sleep( 2*60*1000); publishProgress( i ); i++; } catch( Exception e ){ Log.i("makemachine", e.getMessage() ); } } return "COMPLETE!"; } // -- gets called just before thread begins @Override protected void onPreExecute() { Log.i( "makemachine", "onPreExecute()" ); super.onPreExecute(); } // -- called from the publish progress // -- notice that the datatype of the second param gets passed to this method @Override protected void onProgressUpdate(Integer... values) { super.onProgressUpdate(values); Log.i( "makemachine", "onProgressUpdate(): " + String.valueOf( values[0] ) ); _percentField.setText( ( values[0] * 2 ) + "%"); _percentField.setTextSize( values[0] ); } // -- called if the cancel button is pressed @Override protected void onCancelled() { super.onCancelled(); Log.i( "makemachine", "onCancelled()" ); _percentField.setText( "Cancelled!" ); _percentField.setTextColor( 0xFFFF0000 ); } // -- called as soon as doInBackground method completes // -- notice that the third param gets passed to this method @Override protected void onPostExecute( String result ) { super.onPostExecute(result); Log.i( "makemachine", "onPostExecute(): " + result ); _percentField.setText( result ); _percentField.setTextColor( 0xFF69adea ); _cancelButton.setVisibility( View.INVISIBLE ); } } </code></pre>
