protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// setContentView(R.layout.activity_main);
setContentView(R.layout.main2);
Log.i(Tag, "onCreate: ");
FragmentRecy fr=new FragmentRecy();
FragmentTransaction transaction =
getSupportFragmentManager().beginTransaction();
transaction.replace(R.id.fragment,fr);
transaction.commit();
}
}
ProductAdapter.java

Glide.with(context).load(productslist.get(position).getImageurl())
.thumbnail(0.5f)

推荐答案
您不能替换XML中包含的片段.它将新片段放在旧"片段的顶部.
You cannot replace a fragment that is included in the XML. It will put the new fragment on the top of the "old" fragment.
有关更多详细信息，请参见此问题: Android -片段.replace()不会替换内容-将其放在顶部
Please see this question for more details: Android - fragment .replace() doesn't replace content - puts it on top
