我有一个 Activity ，其中我必须显示具有捏合缩放功能的图像，并且我需要在向下拖动它时关闭 Activity ，就像 Facebook 应用程序中发生的那样。我使用 Chris Banes 的 PhotoView 进行图像缩放，并使用 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:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_centerInParent="true" />
</RelativeLayout>
</com.liuguangqiang.swipeback.SwipeBackLayout>
当我运行此命令时，一切正常，但一旦缩小图像，就会收到此错误:

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。
但是之后，当我运行应用程序并单击图像转到上述 Activity 时，我收到此错误:

造成这种情况的可能原因是什么以及如何使其发挥作用？我真的需要它来工作。谢谢。
最佳答案
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);
}
如果您仔细观察 HackyViewPager ，您会注意到它也在那里。事实上，任何需要支持 xml 膨胀的 View 都应该定义此构造函数。您可能会找到documentation on how to create custom views也很有帮助。
编辑:由于您的目的是捕获抛出的异常，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;
}
}
这应该可以阻止您的应用程序因该特定异常而崩溃，但当然不是“修复”导致抛出 ArrayIndexOutOfBoundsException 的根本问题。它可能会也可能不会导致所需的行为。无论哪种方式，请考虑打开 ticket与 SwipeBack 存储库的维护者合作。
