Question

我的材料设计应用程序面临一个奇怪的问题。有些缩略图正在按预期方式打开和加载详细信息活动，但有些缩略图没有打开，而是发生了崩溃。在此视频中，您可以看到我面临的问题。我将此链接附加到我的项目ZIP文件链接中，My Project

这是主要活动....

} 这是细节活动……

Json link 我正在为此项目进行解析。

这是我的项目的屏幕录像，您可以在其中看到我所面临的问题，recording

这是我尝试调试时的控制台日志。运行正常时，控制台日志为public class ReaderDetailsActivity extends AppCompatActivity { private static final String TAG = ReaderDetailsActivity.class.getSimpleName(); private static final String SAVED_ARRAYLIST = "saved_array_list"; private static final String SAVED_LAYOUT_MANAGER = "layout-manager-state"; private final static String ARTICLE_SCROLL_POSITION = "article_scroll_position"; // View name of the header image. Used for activity scene transitions public static final String VIEW_NAME_HEADER_IMAGE = "detail:header:image"; // View name of the header title. Used for activity scene transitions public static final String VIEW_NAME_HEADER_TITLE = "detail:header:title"; private int position; private Reader reader; private int[] scrollPosition = null; @BindView(R.id.scrollView_details) ScrollView mScrollView; @BindView(R.id.details_fragment_title) TextView mTitle; @BindView(R.id.imageView_details) ImageView mImageView; @BindView(R.id.textView_author_details) TextView mAuthor; @BindView(R.id.textView_published_date) TextView mPublishDate; @BindView(R.id.textView_description) TextView mDescription; @BindView(R.id.floatingActionButton_Up) FloatingActionButton mFloatingActionButton; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_reader_details); ButterKnife.bind(this); Bundle bundle = getIntent().getExtras(); position=0; mFloatingActionButton.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View view) { mScrollView.scrollTo(0,0); } }); ViewCompat.setTransitionName(mImageView, VIEW_NAME_HEADER_IMAGE); ViewCompat.setTransitionName(mTitle, VIEW_NAME_HEADER_TITLE); if (null != bundle) { position = bundle.getInt(MainActivity.POSITION); reader = bundle.getParcelable(MainActivity.READER_DATA); if(null != reader) { mTitle.setText(reader.getTitle()); mPublishDate.setText(reader.getPublishedDate()); mAuthor.setText(reader.getAuthor()); GlideApp.with(this) .load(reader.getPhoto()) .into(mImageView); mDescription.setText(reader.getBody()); } } } @Override public void onSaveInstanceState(Bundle outState) { super.onSaveInstanceState(outState); } @Override protected void onRestoreInstanceState(Bundle savedInstanceState) { super.onRestoreInstanceState(savedInstanceState); scrollPosition = savedInstanceState.getIntArray(ARTICLE_SCROLL_POSITION); if (scrollPosition != null) { mScrollView.postDelayed(new Runnable() { public void run() { mScrollView.scrollTo(scrollPosition[0], scrollPosition[0]); } }, 0); } }

当崩溃时，控制台日志为

最大可包裹尺寸不能超过1mb。在您的应用中为2.1 Mb。在不将应用程序日期传递给下一个活动的情况下，您可以尝试传递商品ID并在下一个活动中加载数据。否则，您可以缓存列表数据，并且可以在详细信息活动中从本地数据库加载数据。如果您在android studio中看不到崩溃日志，因为它设置为“仅显示选定的活动”。在这种情况下，应用会关闭，然后此类日志不会显示在android studio中。将其切换为“无过滤器”，就可以看到所有日志。
