Question

我似乎能够让我的片段工作。 R文件中有一个条目。当然，更改ID并不能解决问题。关于如何解决这个问题的任何想法？

我尝试在Activity中创建它。但我只得到错误。

        Caused by: java.lang.IllegalArgumentException: No view found for 
    id 0x7f080000 (test.jk.com.cameratest:id/relativeLayout) for
 fragment SimpleCameraIntentFragment{42749310 #0 id=0x7f080000}

有我的代码：

@Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_camera);

        FragmentManager fragmentManager = getFragmentManager();
        BaseFragment targetFragment = null;

        targetFragment = SimpleCameraIntentFragment.newInstance(1);

        fragmentManager.beginTransaction()
                .add(R.id.relativeLayout, targetFragment)
                .commit();
    }

这是片段

<RelativeLayout
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/relativeLayout">

    <Button
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Take picture"
        android:id="@+id/buttonTakePicture"
        android:layout_alignParentBottom="true"
        android:layout_centerHorizontal="true" />

    <ImageView
        android:layout_width="32dp"
        android:layout_height="32dp"
        android:id="@+id/imageViewThumb"
        android:layout_alignParentBottom="true"
        android:layout_alignParentLeft="true"
        android:layout_alignParentStart="true"
        android:layout_marginLeft="32dp" />

    <ImageView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:id="@+id/imageViewFullSize"
        android:layout_alignParentLeft="true"
        android:layout_alignParentStart="true"
        android:layout_alignParentRight="true"
        android:layout_alignParentEnd="true"
        android:layout_above="@+id/buttonTakePicture" />
</RelativeLayout>

片段代码：

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

    // Set the image view
    mImageView = (ImageView)view.findViewById(R.id.imageViewFullSize);
    mThumbnailImageView = (ImageView)view.findViewById(R.id.imageViewThumb);
    Button takePictureButton = (Button)view.findViewById(R.id.buttonTakePicture);

    // Set OnItemClickListener so we can be notified on button clicks
    takePictureButton.setOnClickListener(this);

    return view;
}

public static SimpleCameraIntentFragment newInstance(int sectionNumber) {
        SimpleCameraIntentFragment fragment = new SimpleCameraIntentFragment();
        Bundle args = new Bundle();
        args.putInt(ARG_SECTION_NUMBER, sectionNumber);
        fragment.setArguments(args);
        return fragment;
    }

Answer 1

因为我从特定的Activity获取了fragmentManager。我无法发送片段，它必须是发送的活动ID。

这是活动的ID，这是正确的做法。

fragmentManager.beginTransaction()
                .add(**R.id.camActivity**, targetFragment)
                .commit();

此ID无效，因为它是片段的ID

fragmentManager.beginTransaction()
                .add(**R.id.relativeLayout**, targetFragment)
                .commit();

找不到ID 0x7f080000的视图
