I have a managed ProgressDialog that show the status as tasks are
moving along. The Activity.show is kicked off by an AsyncTask
progressUpdates and the final Activity.closeDialog is called through
the AsyncTask as well. Everything works beautifully as long as the
screen is not rotated...
What am I doing wrong? I thought having the Activity manage my dialog
would solve this for me... Here is the code I'm playing with:
public class Enter extends Activity {
ProgressDialog progressDialog;
private final static int PROGRESS_DIALOG_ID = 1;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Button button = (Button)findViewById(R.id.progressbar_button);
button.setOnClickListener(new View.OnClickListener(){
@SuppressWarnings("unchecked")
public void onClick(View v) {
Enter.this.showDialog(PROGRESS_DIALOG_ID);
new AsyncTask(){
@Override
protected Object
doInBackground(Object... params) {
progressDialog.setMax(30);
for (int a = 0; a < 30; a++){
publishProgress(new
Integer((a+1)));
try {
Thread.sleep(1000);
Log.d("Enter",
"Click: " + a);
} catch
(InterruptedException e) {
e.printStackTrace();
}
}
return null;
}
@Override
protected void
onProgressUpdate(Object... values) {
super.onProgressUpdate(values);
Integer progress =
(Integer)values[0];
progressDialog.setProgress(progress.intValue());
}
@Override
protected void onPostExecute(Object
result) {
super.onPostExecute(result);
Enter.this.dismissDialog(PROGRESS_DIALOG_ID);
}
}.execute((Object[]) null);
}
});
}
@Override
protected Dialog onCreateDialog(int id) {
Dialog dialog = null;
if (id == PROGRESS_DIALOG_ID){
progressDialog = new ProgressDialog(this);
progressDialog.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL);
progressDialog.setTitle("Pleae Wait");
progressDialog.setMessage("Running a long process...");
progressDialog.setCancelable(true);
dialog = progressDialog;
}
return dialog;
}
Thanks!
