带有 SwipeBack 的 PhotoView（用于缩放）不起作用

Question

我有一个 activity，我必须在其中显示具有缩放功能的图像，并且我需要在向下拖动它时关闭 activity，就像在 facebook 应用程序中发生的那样。我正在使用 PhotoView by Chris Banes for image zooming and SwipeBack 通过向下拖动来关闭 activity。这是我的 activity :

public class AlternateFullImageActivity extends SwipeBackActivity {
    String photoId;
    String token;
    TinyDB tinyDB;
    RestAdapter restAdapter;
    @Bind(R.id.zoomable)
    ImageView image;
    @Bind(R.id.swipe_layout)
    SwipeBackLayout swipeBackLayout;
    PhotoViewAttacher mAttacher;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_alternate_full_image);
        setDragEdge(SwipeBackLayout.DragEdge.TOP);

        ButterKnife.bind(this);

        tinyDB = new TinyDB(this);
        token = tinyDB.getString("Galleri5 Access Token");

        Intent intent = getIntent();
        photoId = intent.getExtras().getString("ID");

        RequestInterceptor requestInterceptor = new RequestInterceptor() {
            @Override
            public void intercept(RequestFacade request) {
                request.addHeader("Accept", "application/json");
                request.addHeader("Authorization", "Token " + token);
            }
        };
        OkHttpClient okHttpClient = new OkHttpClient();
        restAdapter = new RestAdapter.Builder()
                .setClient(new OkClient(okHttpClient))
                .setLogLevel(RestAdapter.LogLevel.FULL)
                .setEndpoint(API)
                .setRequestInterceptor(requestInterceptor)
                .build();

        PhotoAPI photoAPI = restAdapter.create(PhotoAPI.class);
        photoAPI.getFeed(photoId, new Callback<ImageItem>() {
            @Override
            public void success(ImageItem imageItem, Response response) {
                Picasso.with(AlternateFullImageActivity.this)
                        .load(imageItem.getPhotoUrl())
                        .into(image);
                mAttacher = new PhotoViewAttacher(image);
            }

            @Override
            public void failure(RetrofitError error) {

            }
        });
    }

}

这是我的布局文件：

<com.liuguangqiang.swipeback.SwipeBackLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/swipe_layout"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context="com.galleri5.android.activities.AlternateFullImageActivity">

<RelativeLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="#000000">

    <uk.co.senab.photoview.PhotoView
        android:id="@+id/zoomable"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_centerInParent="true" />

</RelativeLayout>

</com.liuguangqiang.swipeback.SwipeBackLayout>

当我运行这个时，一切正常，但是当我缩小图像时，我得到这个错误：

之后，我阅读了有关 PhotoView 的信息，并按照 github 页面中的说明，尝试为 SwipeBackLayout 创建一个 Hacky 布局。这是代码：

import com.liuguangqiang.swipeback.SwipeBackLayout;

public class HackySwipeBackLayout extends SwipeBackLayout {
    public HackySwipeBackLayout(Context context) {
        super(context);
    }

    @Override
    public boolean onInterceptTouchEvent(MotionEvent ev) {
        try {
            return super.onInterceptTouchEvent(ev);
        } catch (IllegalArgumentException e) {
            e.printStackTrace();
            return false;
        }
    }
}

然后我使用新的 HackySwipebackLayout 替换了早期的布局文件。

但是在那之后，当我运行应用程序并单击图像转到上面 activity 时，我收到此错误：

这可能是什么原因以及如何让它发挥作用？我真的需要它来工作。谢谢。

Answer 1

java.lang.NoSuchMethodException: <init> [class android.content.Context, interface android.util.AttributeSet]

您的 HackySwipeBackLayout 缺少构造函数：

public HackySwipeBackLayout(Context context, AttributeSet attrs) {
    super(context, attrs);
}

如果你仔细看看 HackyViewPager, you'll notice that it is in there too. As a matter of fact, any view that needs to support inflating from xml should have this constructor defined. You may find the documentation on how to create custom views 也很有帮助。

编辑：由于您的意图是捕获抛出的异常，因此请确保相应地捕获 ArrayIndexOutOfBoundsException：

@Override public boolean onInterceptTouchEvent(MotionEvent ev) {
    try {
        return super.onInterceptTouchEvent(ev);
    } catch (ArrayIndexOutOfBoundsException e) {
        e.printStackTrace();
        return false;
    }
}

这应该会阻止您的应用程序因这个特定异常而崩溃，但当然不是 'fix' 导致首先抛出 ArrayIndexOutOfBoundsException 的根本问题。它可能会或可能不会导致所需的行为。无论哪种方式，请考虑与 SwipeBack 存储库的维护者一起打开 ticket。

带有 SwipeBack 的 PhotoView（用于缩放）不起作用
