我正在使用 PhotoView 库，但是在将它与 viewpager 一起使用时，我在缩放时出现错误。

虽然，缩放效果很好，但是当图像变远时，就会发生错误并且我的活动崩溃。这是我在 viewapager 中的代码：

@Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {
        pv = new PhotoView(getActivity());
        pv.setLayoutParams(new LayoutParams(LayoutParams.MATCH_PARENT,
                LayoutParams.MATCH_PARENT));
        imageLoader.DisplayImage(mContent, pv);
        LinearLayout layout = new LinearLayout(getActivity());
        layout.setLayoutParams(new LayoutParams(LayoutParams.MATCH_PARENT,
                LayoutParams.MATCH_PARENT));
        layout.setGravity(Gravity.CENTER);
        layout.addView(pv);

        return layout;
    }

我用谷歌搜索了这个问题，但找不到任何合适的解决方案！有什么建议吗？？多谢你们

我的整个代码：

public class viewpager extends SherlockFragmentActivity {

AllPhonesDatabase apd;
Bundle gotBasket;

@Override
protected void onCreate(Bundle savedInstanceState) {
    // TODO Auto-generated method stub
    super.onCreate(savedInstanceState);
    requestWindowFeature(Window.FEATURE_NO_TITLE);
    setContentView(R.layout.simple_circles);

    apd = new AllPhonesDatabase(this.getApplicationContext()).open();
    gotBasket = viewpager.this.getIntent().getExtras();
    final String imageurl1 = gotBasket.getString("Imageurl1");
    final String imageurl2 = gotBasket.getString("Imageurl2");
    final String imageurl3 = gotBasket.getString("Imageurl3");

    TestFragmentAdapter mAdapter = new TestFragmentAdapter(
            this.getSupportFragmentManager(), imageurl1, imageurl2,
            imageurl3);
    ViewPager mPager = (ViewPager) findViewById(R.id.pager);
    mPager.setAdapter(mAdapter);
    CirclePageIndicator mIndicator = (CirclePageIndicator) findViewById(R.id.indicator);
    mIndicator.setViewPager(mPager);

}

}

class TestFragmentAdapter extends FragmentPagerAdapter {
    protected static String[] CONTENT;

    private int mCount;

    public TestFragmentAdapter(FragmentManager fm, String imageurl1,
            String imageurl2, String imageurl3) {
        super(fm);
        CONTENT = new String[] { imageurl1, imageurl2, imageurl3 };
        mCount = CONTENT.length;
    }

    @Override
    public Fragment getItem(int position) {
        return TestFragment.newInstance(CONTENT[position % CONTENT.length]);
    }

    @Override
    public int getCount() {
        return mCount;
    }

    @Override
    public CharSequence getPageTitle(int position) {
        return TestFragmentAdapter.CONTENT[position % CONTENT.length];
    }

    public void setCount(int count) {
        if (count > 0 && count <= 10) {
            mCount = count;
            notifyDataSetChanged();
        }
    }


public final class TestFragment extends Fragment {
    private static final String KEY_CONTENT = "TestFragment:Content";
    public ImageLoader2 imageLoader;
    PhotoView pv;

    public static TestFragment newInstance(String content) {
        TestFragment fragment = new TestFragment();
        StringBuilder builder = new StringBuilder();
        for (int i = 0; i < 1; i++) {
            builder.append(content).append(" ");
        }
        builder.deleteCharAt(builder.length() - 1);
        fragment.mContent = builder.toString();
        return fragment;
    }

    private String mContent = "???";

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        imageLoader = new com.androidarabia.lazylist.ImageLoader2(
                this.getActivity());
        if ((savedInstanceState != null)
                && savedInstanceState.containsKey(KEY_CONTENT)) {
            mContent = savedInstanceState.getString(KEY_CONTENT);
        }
    }


    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {
        pv = new PhotoView(getActivity());
        pv.setLayoutParams(new LayoutParams(LayoutParams.MATCH_PARENT,
                LayoutParams.MATCH_PARENT));
        imageLoader.DisplayImage(mContent, pv);
        LinearLayout layout = new LinearLayout(getActivity());
        layout.setLayoutParams(new LayoutParams(LayoutParams.MATCH_PARENT,
                LayoutParams.MATCH_PARENT));
        layout.setGravity(Gravity.CENTER);
        layout.addView(pv);

        return layout;
    }

    @Override
    public void onSaveInstanceState(Bundle outState) {
        super.onSaveInstanceState(outState);
        outState.putString(KEY_CONTENT, mContent);
    }

在某些地方，这似乎是一个错误。我不确定它是在 PhotoViewer 端还是在 androids 端。我通过在我自己的自定义视图寻呼机中使用此代码解决了这个问题：

public class HackyViewPager extends ViewPager {


public HackyViewPager(Context context)
{
    super(context);
}

public HackyViewPager(Context context, AttributeSet attrs)
{
    super(context, attrs);
}
@Override
public boolean onInterceptTouchEvent(MotionEvent ev)
{
    try
    {
            return super.onInterceptTouchEvent(ev);
    }
    catch (IllegalArgumentException e)
    {
    }
    catch (ArrayIndexOutOfBoundsException e)
    {

    }
    return false;
}
}

我使用此代码没有任何问题，放大和缩小似乎工作正常。在你的源代码中创建这个类，然后你可以在你的 xml 文件中引用它，如下所示：

<my.default.package.HackyViewPager
    android:id="@+id/pager"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    />

可能您应该检查这是否与此处的先前问题相似。 java.lang.IllegalArgumentException：pointerIndex 超出范围异常 - dispatchTouchEvent

显然我同意 hacky view pager 的事情，但我想对于完美的实现，必须使用 photoViewAttacher.update()，在每次图像资源更改后，就像成功一样，使用相应图像加载库的失败侦听器

  1. 创建一个新类HackyViewPager并粘贴此代码

     public class HackyViewPager extends ViewPager {


 public HackyViewPager(Context context) {
     super(context);
 }

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


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

         }
         return false;
     }
 }

  2. 一个你的xml布局改变viewPager组件的类

     <android.support.v4.view.ViewPager
         android:layout_width="match_parent"
         android:elevation="0dp"
         android:id="@+id/viewPager"
         android:layout_height="match_parent">
 </android.support.v4.view.ViewPager>

    至

     <com.yourpackage.HackyViewPager
         android:layout_width="match_parent"
         android:elevation="0dp"
         android:id="@+id/viewPager"
         android:layout_height="match_parent">
 </com.yourpackage.HackyViewPager>

  3. 用 HackyViewPager 类声明你的 viewPager 变量

     HackyViewPager viewPager;

    onCreate 方法内部

     viewPager = (HackyViewPager) findViewById(R.id.viewPager);
