i've build an AlertDialog which shows three items:
AlertDialog.Builder builder = new AlertDialog.Builder(myActivity);
...
builder.setItems(items, new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int item) {
if(item==0){ //do stuff}
else if(item==1){//do other stuff}
else if(item==2){//show other dialog}
...
now i want to display another dialog when the user selects the third item (item==2). My approach is the following:
Dialog otherDialog = new Dialog(myActivity.savedApplicationContext);
otherDialog.setContentView(R.layout.other_layout);
otherDialog.setTitle(getString(R.string.update_dialog));
dialog.dismiss(); //dismiss old dialog
otherDialog.show();
This doesn't work :( An exception thrown:

I've searched on stackoverflow/the inet but the solution that was meantioned there was to pass the applicationContext of the Activity to the Dialog (which i did in this case, i saved an reference of the activitys applicationContext in a private variable: myActivity.savedApplicationContext
Fixed the problem.
Instead of savedApplicationContext = getApplicationContext();
i used savedApplicationContext = this;
now it works :-)
