Question

我有一个Button按钮，它可以在ListView中选中所有选中的CheckBox，并显示AlertDialog中所有选中的复选框。

我在for循环中迭代所有元素，我有一个positiveButton和一个negativeButton - 当我按下negativeButton时，我想取消所有对话框，然后返回到应用程序。
但相反，当我按下negativeButton时，它会逐个迭代。

btnDialog = (Button) findViewById(R.id.btnDialog);
btnDialog.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        StringBuffer responseText = new StringBuffer();
        //responseText.append("הפריטים שנבחרו הם: \n");
        Models models = new Models();
        //List<Models> modelList = new ArrayList<>();
        AlertDialog.Builder alertDialogBuilder = new AlertDialog.Builder(context);
        alertDialogBuilder.setTitle("Diet Product");
        responseText.append("הפריטים שנבחרו הם: \n");
        Log.d(responseText.toString(), msg);

        for (int i = 0; i < (modelList.size()); i++) {
            models = modelList.get(i);
            if (models.isSelected()) {
                alertDialogBuilder
                        .setMessage(responseText.append(models.getName() + " : " + models.getProtein() + "\n"))
                        .setCancelable(false)
                        .setPositiveButton("Yes", new DialogInterface.OnClickListener() {
                            public void onClick(DialogInterface dialog, int id) {
                                // if this button is clicked, close current activity
                                MainActivity.this.finish();
                            }
                        })
                        .setNegativeButton("No", new DialogInterface.OnClickListener() {
                            public void onClick(DialogInterface dialog, int id) {

                                dialog.dismiss();
                            }
                        });
                AlertDialog alertDialog = alertDialogBuilder.create();
                alertDialog.show();

            }
        }

    }
});
