java - 如何处理 StackOveflowError: stack size 8MB using PhotoView in Viewpager with gldev4？

Question

尝试使用 photoView 库在 ViewPager Activity 中滑动时出现此错误，我使用 Glide 作为图像，并且 url 来自 Intent（url 是数组）。我还使用模型类从 firebase 数据库下载数据。

这是日志：

ViewPager 活动，我从意图中获取 url，解析它以将其转换为数组，因为它是多个字符串连接的。滑行使用它来显示图像。第一张图片显示并没有崩溃，但是当我滑动到第二张图片时，它花了几秒钟然后崩溃（只有活动崩溃而不是应用程序），但是如果我从第二张图片滑动到第三张图片它之前突然崩溃了甚至显示它。

public class ViewPagerActivity extends AppCompatActivity {

String imageList = null;
String[] propertyImageArray = {};


@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_view_pager);
    //get imageList url from Intent
    imageList = getIntent().getStringExtra("imageList");
    propertyImageArray = imageList.split(",");
    ViewPager viewPager = findViewById(R.id.view_pager);
    viewPager.setAdapter(new SamplePagerAdapter());
}

class SamplePagerAdapter extends PagerAdapter {

    @Override
    public int getCount() {
        return propertyImageArray.length;
    }

    @Override
    public View instantiateItem(ViewGroup container, int position) {
        //Must call notifyDataSetChanged before adding imageList to View
        //otherwise it'll crash
        notifyDataSetChanged();
        PhotoView photoView = new PhotoView(ViewPagerActivity.this);
        GlideApp.with(ViewPagerActivity.this)
                .load(propertyImageArray[position])
                .fitCenter()
                .into(photoView);

        // Now just add PhotoView to ViewPager and return it
        container.addView(photoView,
                ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT);
        return photoView;


    }

    @Override
    public void destroyItem(ViewGroup container, int position, Object object) {
        container.removeView((View) object);
    }

    @Override
    public boolean isViewFromObject(View view, Object object) {
        return view == object;
    }

这是将意图发送到 ViewPagerActivity 的类，

public class PropertyLotDetail extends AppCompatActivity implements Toolbar.OnMenuItemClickListener {


@Override
protected void onCreate( Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.property_lot_detail);
    Toolbar myToolbar = (Toolbar) findViewById(R.id.kunuk_toolbar);
    myToolbar.inflateMenu(R.menu.menu_detail);
    setSupportActionBar(myToolbar);

    myToolbar.setOnMenuItemClickListener(this);

    //collect our intent
    Intent intent = getIntent();
    Property property = intent.getParcelableExtra("Property");

    //collect all property values from Parcelable
    int price = property.getPrice();
    String address = property.getAddress();
    final  String propertyImage = property.getPropertyImage();
    float lotDim = property.getLotDim();
    String propertyDesc = property.getPropertyDesc();
    String lotTerrainType = property.getLotTerrainType();
    String lotTerrainDimExt = property.getLotTerrainDimExt();
    String lotTerrainSteepness = property.getLotTerrainSteepness();
[...]
 //Bind the data from the Parcelable to the Views
    TextView addressDetail = findViewById(R.id.post_address);
    addressDetail.setText(String.valueOf(address));

    String currencyPrice = NumberFormat //Format the price variable in currency form
            .getCurrencyInstance(Locale.US)
            .format(price);
    TextView priceDetail = findViewById(R.id.post_price);
    priceDetail.setText(currencyPrice);

    ImageView imageView = findViewById(R.id.post_propertyImage);
    imageView.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            startActivity(new Intent(getApplicationContext(),
                    ViewPagerActivity.class)
                    .putExtra("imageList", propertyImage)
                    .addFlags(Intent.FLAG_ACTIVITY_NEW_TASK));

        }
    });

    //take one long string containing multiple url and parse it
    String propertyImageArray[] = propertyImage.split(",");

    //TODO add loading icon for placeholder

    // Download directly from StorageReference using Glide
    // (See MyAppGlideModule for Loader registration)
    GlideApp.with(getApplication())
            .load(propertyImageArray[0])
            .fitCenter()
            .into(imageView);

这是最相关的信息。请帮忙

我刚刚摆脱了notifyDataChanged()方法调用。我认为它已被自动调用，我不需要这样做，这就是堆栈跟踪导致无限递归的原因。这正是我的想法。

public class ViewPagerActivity extends AppCompatActivity {

String imageList = null;
String[] propertyImageArray = {};


@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_view_pager);
//get imageList url from Intent
imageList = getIntent().getStringExtra("imageList");
propertyImageArray = imageList.split(",");
ViewPager viewPager = findViewById(R.id.view_pager);
viewPager.setAdapter(new SamplePagerAdapter());
}

class SamplePagerAdapter extends PagerAdapter {

@Override
public int getCount() {
    return propertyImageArray.length;
}

@Override
public View instantiateItem(ViewGroup container, int position) {
    //Must call notifyDataSetChanged before adding imageList to View
    //otherwise it'll crash

notifyDataSetChanged();

    PhotoView photoView = new PhotoView(ViewPagerActivity.this);
    GlideApp.with(ViewPagerActivity.this)
            .load(propertyImageArray[position])
            .fitCenter()
            .into(photoView);

    // Now just add PhotoView to ViewPager and return it
    container.addView(photoView,
            ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT);
    return photoView;


}

@Override
public void destroyItem(ViewGroup container, int position, Object object) {
    container.removeView((View) object);
}

@Override
public boolean isViewFromObject(View view, Object object) {
    return view == object;
}

抱歉格式不好，不知道如何在代码中制作罢工线
