                    dialog.dismiss();
                }
            });
        }

Answer 1

使用以下代码：

@Override
public void onClick(View v) {
    imgJuice.setImageDrawable(resources
        .getDrawable(R.drawable.imgJuiceOrange));
    dialog.dismiss();
}

imgJuiceOrange是drawable而不是id。

此外，您忘记在此处添加dialog.show()： -

imgJuice.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View v) {
            // TODO Auto-generated method stub
            final Resources resources = getResources();
            final Dialog dialog = new Dialog(getActivity(),
                    android.R.style.Theme_Dialog);
            dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
            dialog.setContentView(R.layout.choose_juice_image_dialog);

            ImageView imgJuiceOrange = (ImageView) dialog
                    .findViewById(R.id.imgJuiceOrange);
            imgJuiceOrange.setOnClickListener(new View.OnClickListener() {

                @Override
                public void onClick(View v) {

                    imgJuice.setImageDrawable(resources
                            .getDrawable(R.id.imgJuiceOrange));
     // also i have tried with setImageResource but nothing will be happen 

                    dialog.dismiss();
                }
            });
            //Dialog Show code missing
            dialog.show();
        }
