Question

生成器。我想在解雇或取消时执行某些操作。所以我使用了setOnDismissListener和setOnCancelListener，如下面的代码。但是这种方法都没有检测到何时解雇AlertDialog.Builder。

   private static void openOptionDialog(final Context context, Item[] items, String title, DialogInterface.OnClickListener positiveClick) {
        ListAdapter adapter = new ArrayAdapter<Item>(
                context, android.R.layout.select_dialog_item, items) {
            @Override
            public View getView(int position, View convertView, ViewGroup parent) {
                View view = super.getView(position, convertView, parent);
                TextView textView = (TextView) view.findViewById(android.R.id.text1);
                Item item = getItem(position);
                textView.setText(item.string);
                textView.setTextSize(16f);
                textView.setCompoundDrawablesWithIntrinsicBounds(item.icon, 0, 0, 0);
                textView.setCompoundDrawablePadding(BDevice.getPixelFromDp(context, 15));
                return view;
            }
        };

        AlertDialog.Builder builder = AlertUtils.getBuilder(context);
        builder.setTitle(title);
        builder.setAdapter(adapter, positiveClick);
        builder.create().show();

        builder.setOnDismissListener(new DialogInterface.OnDismissListener() {
            @Override
            public void onDismiss(DialogInterface dialog) {
                WidgetSettings preference = new WidgetSettings(context);
                if(preference.canWidgetTooteets()){
                    preference.clear();
                }
            }
        });

        builder.setOnCancelListener(new DialogInterface.OnCancelListener() {

            public void onCancel(DialogInterface dialog) {
                WidgetSettings preference = new WidgetSettings(context);
                if(preference.canWidgetTooteets()){
                    preference.clear();
                }
            }
        });

    }

getBuilder中的AlertUtils方法如下，

public static AlertDialog.Builder getBuilder(Context context) {
        return new AlertDialog.Builder(context, R.style.Dialog);
    }

您能否建议我为此找到解决方案？提前谢谢。

Answer 1

仅使用 AlertDialog 而不是 AlertDialog.Builder ，并添加 setOnDismissListener ，因为它可以正常工作。

例如

AlertDialog alert = builder.create();
alert.setOnDismissListener(yourDismissListener);
alert.show();

AlertDialog alert = builder.create();
alert.setOnCancelListener(yourCancelListener);
alert.show();

Answer 2

尝试alert.cancel()代替alert.dismiss()并添加OnCancelListener，如下所示：

builder.setOnCancelListener(new DialogInterface.OnCancelListener() {
        @Override
        public void onCancel(DialogInterface dialog) {
            dialog.dismiss();
        }
    });

AlertDialog.Builder拒绝在API 17 android中工作
