My activity opens a dialog. When it closes I need the function ReloadTable() to be executed. So I am trying to use setOnDismissListener but its not getting triggered. Could someone please help what I am doing wrong?

谢谢！

AlertDialog.Builder builder;
AlertDialog alertDialog;
Context mContext = getApplicationContext();
LayoutInflater inflater = (LayoutInflater) mContext.getSystemService(LAYOUT_INFLATER_SERVICE);
View layout = inflater.inflate(R.layout.transaction, null);
builder = new AlertDialog.Builder(new ContextThemeWrapper(TransactionsList.this , R.style.dialogwithoutdim));
builder.setView(layout);
alertDialog = builder.create();
alertDialog.setOnDismissListener(new OnDismissListener() {
    public void onDismiss(final DialogInterface dialog) {
        ReloadTable();
    }
});

builder.show();

推荐答案

public class MyActivity extends Activity implements DialogInterface.OnCancelListener{
    @Override
    public void onCreate(Bundle state) {
       .....
       alertDialog.setOnCancelListener(this);
       alertDialog.show();
    }
    @Override
    public void onCancel(DialogInterface dialog) {
        dialog.dismiss();
        .....
    }
}
