Question

我开发了一个健身应用程序，因此，当用户单击片段中的“初学者”按钮时，它应该会显示一系列练习。我的第二个片段（片段2）最初在工作，但是一旦我自定义该片段并添加了图像等，它就停止了工作，我无法找出错误所在。

这是给我老师的。

以下是出现错误的部分：

public class Fragment2 extends Fragment {

    @Nullable
    @Override
    public View onCreateView(@NonNull LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
        View view = inflater.inflate(R.layout.fragment2,container,false);
        return view;
    }
}

这是我的错误代码：

Answer 1

这是由于您在Fragment中添加了图片。因此，出于您的应用程序的考虑，请参考https://developer.android.com/topic/performance/graphics/load-bitmap以将bitmaps或drawables有效地加载到application中。
