Question

我通过onclick按钮替换我的片段但是得到这个错误plz帮助这是我的详细活动片段

public class DetailActivityFragment extends Fragment{

    TextView textView;
    ImageView imageView;
    TextView details;
    Button button;
    public DetailActivityFragment() {
    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
        View view=inflater.inflate(R.layout.fragment_detail, container, false);


       Bundle getBundle = getActivity().getIntent().getExtras();

        String name = getBundle.getString("NAME");
        textView= (TextView) view.findViewById(R.id.bioname);
        textView.setText(name);
        imageView= (ImageView) view.findViewById(R.id.imageView);
        imageView.setImageResource(getBundle.getInt("IMAGE"));
        Log.v("test", "images are coming");
         button= (Button) view.findViewById(R.id.quickfacts);
        button.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                Fragment fragment = new QuickFacts();
                FragmentTransaction fragmentTransaction =
                        getFragmentManager().beginTransaction();

                fragmentTransaction.replace(R.id.quickfacts, fragment);
                fragmentTransaction.setTransition(FragmentTransaction.TRANSIT_FRAGMENT_FADE);
                fragmentTransaction.addToBackStack(null);
                fragmentTransaction.commit();
            }
        });
        return view;
    }
}

这是我的qucikfacts.xml，它是quickfact片段的一部分，其中fragmeht在点击时替换

<FrameLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:id="@+id/quickfacts"
    ></FrameLayout>
<!-- TODO: Update blank fragment layout -->
<TextView
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:text="@string/hello_blank_fragment" />

这是我的片段细节，我有那个按钮

<ImageButton
    android:layout_width="150dp"
    android:layout_height="250dp"
    android:scaleType="centerCrop"
    android:id="@+id/imageView"

    android:layout_marginRight="10dp"
    android:layout_centerHorizontal="true"
    android:layout_below="@+id/bioname" />

<Button
    android:id="@+id/quickfacts"

    android:text="Quick Facts"
    android:textColor="#FFFFFF"
    android:textSize="25sp"

    android:layout_width="150dp"
    android:layout_height="60dp"
    android:background="@drawable/quick_facts"
    android:shadowColor="#A8A8A8"
    android:shadowDx="0"
    android:shadowDy="0"
    android:shadowRadius="5"
    android:layout_below="@+id/imageView"
    android:layout_alignParentStart="true" />
<Button
    android:id="@+id/biodetail"

    android:text="Biography"
    android:textColor="#FFFFFF"
    android:textSize="25sp"

    android:layout_width="150dp"
    android:layout_height="60dp"
    android:background="@drawable/quick_facts"
    android:shadowColor="#A8A8A8"
    android:shadowDx="0"
    android:shadowDy="0"
    android:shadowRadius="5"
    android:layout_below="@+id/imageView"
    android:layout_alignParentEnd="true" />
<Button
    android:id="@+id/exit"

    android:text="Exit"
    android:textColor="#FFFFFF"
    android:textSize="25sp"

    android:layout_width="150dp"
    android:layout_height="60dp"
    android:background="@drawable/quick_facts"
    android:shadowColor="#A8A8A8"
    android:shadowDx="0"
    android:shadowDy="0"
    android:shadowRadius="5"
    android:layout_alignTop="@+id/quotes"
    android:layout_alignStart="@+id/biodetail"
    android:layout_alignParentEnd="true" />

<Button
    android:id="@+id/quotes"

    android:text="Quotes"
    android:textColor="#FFFFFF"
    android:textSize="25sp"

    android:layout_width="150dp"
    android:layout_height="60dp"
    android:background="@drawable/quick_facts"
    android:shadowColor="#A8A8A8"
    android:shadowDx="0"
    android:shadowDy="0"
    android:shadowRadius="5"
    android:layout_below="@+id/quickfacts"
    android:layout_alignParentStart="true"
    android:layout_marginTop="43dp" />

Answer 1

fragmentTransaction.replace(R.id.quickfacts, fragment);您确定自己的片段在按钮内吗？

button= (Button) view.findViewById(R.id.quickfacts);或者是您的按钮frame layout ?

我认为你们中的任何一个都错了。

android.support.v7.widget.AppCompatButton无法强制转换为android.view.ViewGroup
