Answer 1

In xml file -

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">

      <ImageView
          android:layout_height="wrap_content"
          android:layout_width="wrap_content"
          android:id="@+id/my_image"/>

</LinearLayout>

In activity show your custom dialog box using below code -

AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
LayoutInflater inflater = getActivity().getLayoutInflater();
View dialogView = inflater.inflate(R.layout.dialog, null);
builder.setView(dialogView)
                    .setPositiveButton(R.string.create, new DialogInterface.OnClickListener() {
                        @Override
                        public void onClick(DialogInterface dialog, int which) {

                        }
                    })
                    .setNegativeButton(R.string.cancel, new DialogInterface.OnClickListener() {
                        @Override
                        public void onClick(DialogInterface dialog, int which) {

                        }
                    }).create().show();

使用匹配父级中的imageview对新片段进行事务处理。
