我有一个片段实现的列表视图。当我单击一个项目时，我想过渡到详细信息片段，我想在另一片段中显示详细信息，在该片段中，我对该图像有一个imageview，而名称，价格和详细信息则为3个textview。我尝试了几种变体，但它们没有成功。非常感谢
items.java
public class items {
// Name of the object
private String lName;
// Costs
private String lPrice;
// Details
private String lDetails;
// Image resource id
private int lImageId;
// Constructor
public items(String ObjectName,String ObjectPrice,int ImageResourceId,String DetailsItem){
lName=ObjectName;
lPrice=ObjectPrice;
lImageId=ImageResourceId;
lDetails=DetailsItem;
}
// Getters
public String getlName() { return lName; }
public String getlPrice(){ return lPrice; }
public int getlImageId(){ return lImageId; }
public String getlDetails() { return lDetails; }
}
itemsAdapter.java
public class itemsAdapter extends ArrayAdapter<items>{

嗨，您可以使用以下代码。
首先将一个接口创建为适配器类和“第一片段”实现接口。
接口具有一种回调方法。因此，当用户单击列表项时，则使用下面的方法
@override callback（）{
}
进入第一片段。
在过渡代码下方的内部回调方法。
FragmentTransaction fragmentTransaction = getSupportFragmentManager()
.beginTransaction();
Fragment profileFragment = new MovieDetailFragment();//the fragment you want to show
profileFragment.setArguments(bundle);
fragmentTransaction
.replace(R.id.content_frame, profileFragment);//R.id.content_frame is the layout you want to replace
fragmentTransaction.addToBackStack(null);
fragmentTransaction.commit();
