Question

我正在尝试在扩展片段的类上创建可缩放图像。我还是新手，所以这个错误让我感到害怕。这是map.java。

public class map extends Fragment {
public static final String TAG = "map";
public TouchImageView image;
private DecimalFormat df;
Context context = getActivity();

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {

    View rootView = inflater.inflate(R.layout.d_map, container, false);
    getActivity().setRequestedOrientation(
            ActivityInfo.SCREEN_ORIENTATION_UNSPECIFIED);

    image = (TouchImageView) rootView.findViewById(R.id.img);
    return rootView;
}

}

XML文件：

<?xml version="1.0" encoding="utf-8"?>

<com.example.ok.TouchImageView
    android:id="@+id/img"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_alignParentLeft="true"
    android:layout_alignParentTop="true"
    android:src="@drawable/main_map"
    android:layout_alignParentRight="true"
    android:layout_alignParentEnd="true" />

错误：

 android.view.InflateException: Binary XML file line #5: Error inflating class com.example.ok.TouchImageView

这是TouchImageView.java
