android - AlertDialog setOnDismissListener 不工作

Question

我的 Activity 打开了一个对话框。当它关闭时，我需要执行函数 ReloadTable()。所以我正在尝试使用 setOnDismissListener 但它没有被触发。有人可以帮助我做错什么吗？

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();

Answer 1

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();
        .....
    }
}
