In my Application I need to call a function(Which update the valuesof textviews),I need to call this function inside AlertDialg when OK button is pressed.
the issue is how i can call RefreshData.execute() after ok button of dialog is pressed ?
this is one of the Errors :
android.view.WindowManager$BadTokenException: Unable to add window -- token null is not for an application.
the code:
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
setContentView(R.layout.details);
Bundle extras = getIntent().getExtras();
if (extras != null) {
x = extras.getString("key").toString();
} else {
Toast.makeText(getBaseContext(), "null", 0).show();
}
tv_summary = (TextView) findViewById(R.id.tv_summary);
tv_servings_result = (TextView) findViewById(R.id.tv_servings_result);
tv_calories_result = (TextView) findViewById(R.id.tv_calories_result);
tv_fat = (TextView) findViewById(R.id.tv_fat);
tv_monofat = (TextView) findViewById(R.id.tv_monofat);
tv_satfat = (TextView) findViewById(R.id.tv_satfat);
tv_ch = (TextView) findViewById(R.id.tv_ch);
tv_sug = (TextView) findViewById(R.id.tv_sug);
new LoadDetails().execute();
Button MealSize = (Button) findViewById(R.id.btn_size);
MealSize.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
show();
Toast.makeText(getBaseContext(), F + "", 0).show();
}
});
}
void Refresh() {
new RefreshData().execute();
}
void show() {
AlertDialog.Builder alert = new AlertDialog.Builder(this);
alert.setTitle("Title");
alert.setMessage("Message");
final EditText input = new EditText(this);
alert.setView(input);
alert.setPositiveButton("Ok", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int whichButton) {
F = Float.parseFloat(input.getText().toString());
new RefreshData().execute();
}
});
alert.setNegativeButton("Cancel",
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int whichButton) {
// Canceled.
}
});
alert.show();
}
private class RefreshData extends AsyncTask<Void, Void, Void> {
private ProgressDialog progressDialog;
@Override
protected void onPreExecute() {
this.progressDialog = ProgressDialog.show(getBaseContext(), "",
" Loading...");
}
@Override
protected void onPostExecute(final Void unused) {
this.progressDialog.dismiss();
try {
this.progressDialog.dismiss();
tv_servings_result.setText(servings_result + "" + F);
tv_calories_result.setText(cal + "g");
tv_fat.setText(ff + "");
tv_monofat.setText(mm + "");
tv_satfat.setText(sasa + "");
tv_ch.setText(chch + "");
tv_sug.setText(sugar + "");
} catch (Exception e) {
Log.e("log_tag",
"Eraaaaaaaaaaaaaaaaaaa connection" + e.toString());
}
}
@Override
protected Void doInBackground(Void... params) {
try {
sugar = Float.valueOf(sug).floatValue();
sugar *= F;
cal = Float.valueOf(calories_result).floatValue();
cal *= F;
ff = Float.valueOf(fat).floatValue();
ff *= F;
mm = Float.valueOf(monofat).floatValue();
mm *= F;
} catch (Exception e) {
Log.e("log_tag",

}
return null;
}
}
