您好，我想用按钮点击打开一个片段，但是按钮在布局snipet_profile.xml中，我现在已经在fragment_profile中包含了snipet_profile.xml，当我点击按钮时，它打开了我想打开的片段，我想在按钮点击时打开的片段是editprofile
好的，如果你觉得有点困惑，看看我的代码
我尝试了一种方法，首先你必须找到有按钮的布局，在我的例子中，它是相对的，所以我用这种方式实现
java

RelativeLayout relativeLayout = view.findViewById(R.id.snipet_profile); // R.id.snipet_profile is the layout that i have included in Profile Fragment

现在是按钮

Button editProfileButton;
editProfileButton = relativeLayout.findViewById(R.id.edit_profile_button); t// i have included relativelayout.findViewById so it can navigate or in simple this method i found

错误//在实现答案后

现在是完整的代码
profile_fragment.java

Button editProfileButton;
@SuppressLint("SourceLockedOrientationActivity")
    @Nullable
    @Override
    public View onCreateView(@NonNull LayoutInflater inflater, @Nullable ViewGroup container, 
    @Nullable Bundle savedInstanceState) {
        View view = inflater.inflate(R.layout.fragment_profile, container, false);
        RelativeLayout relativeLayout = view.findViewById(R.id.snipet_profile);
        editProfileButton = relativeLayout.findViewById(R.id.edit_profile_button);
        editProfileButton.setOnClickListener(this::onClick);// added this line of code according to the answer

        return view;
    }
@Override
    public void onClick(View view) {
        Fragment fragment;
        if (view.getId() == R.id.edit_profile_button) {
            fragment = new Edit_Profile(); // Edit_Profile fragment
            replaceFragment(fragment);
        }
    }

    public void replaceFragment(Fragment fragment) {
        FragmentTransaction transaction = getParentFragmentManager().beginTransaction();
        transaction.replace(R.id.fragment_container, fragment);
        transaction.addToBackStack(String.valueOf(new Profile_Fragment()));
        transaction.commit();
    }

fragment_profile.xml

        <include
            android:id="@+id/snipet_profile"
            layout="@layout/snipet_profile" />

</LinearLayout>

snipet_profile.xml

</Button>

更新1//添加了editprofile java和xml文件
edit_profile.java//这是我试图在单击按钮时打开的片段

public class Edit_Profile extends Fragment {
    private CircleImageView profilePhoto;

    @Override
    public View onCreateView(@NonNull LayoutInflater inflater, @Nullable @org.jetbrains.annotations.Nullable ViewGroup container, @Nullable @org.jetbrains.annotations.Nullable Bundle savedInstanceState) {
        View view = inflater.inflate(R.layout.fragment_edit_profile, container, false);
        profilePhoto = view.findViewById(R.id.circleImageView);
        setProfileImage();
        initImageLoader();

        return view;
    }

    private void initImageLoader() {
        UniversalImageLoader universalImageLoader = new UniversalImageLoader(getContext());
        ImageLoader.getInstance().init(universalImageLoader.getConfig());
    }

    private void setProfileImage() {
        String imgUrl = "https://64.media.tumblr.com/1276b4edef49034af70bda14325385e3/d8872c747cafa206-96/s500x750/aa915fc49a84b5295f0cd44145d655b66eb906a6.jpg";

你必须把它设置好 OnClickListener 为此 Button ... 使用 editProfileButton.setOnClickListener(this); - this 用作您的 Fragment implements View.OnClickListener 编辑：嗯，你的stacktrace说明了一切。。。

IllegalArgumentException: adjustViewBounds not supported.
    at de.hdodenhof.circleimageview.CircleImageView.setAdjustViewBounds(CircleImageView.java:141)

移除 android:adjustViewBounds="true" 声明了来自xml的行 CircleImageView . 并删除 android:scaleType="centerCrop" . 阅读本文，您可以在其中找到：
circleimageview的scaletype总是居中裁剪，如果我们试图更改它，就会出现异常。因此，它是完美的个人资料图片。
不支持启用adjustviewbounds，因为这需要不受支持的scaletype
