Java Android应用程序中的充气异常-ListView

我是一个初学者，完全无法修复充气异常。我有一个线索，膨胀异常是由一个bean类的序列化引起的，然而，这一切是如何一起工作的超出了我的理解

logcat如下所示，请注意，当我打开一个包含ListView的对话框时，就会发生这种情况，ListView又基于我刚才提到的beans类：

首先，我有前面提到的bean类Media.java：

public class Media implements Parcelable {
    private String duration;
    private String title;
    private URL url;
    private String contentType;
    private Bitmap thumbnail;
    private String resolution;
    private String bandwidth;

public Media(Parcel parcel) throws MalformedURLException {
    this.duration = parcel.readString();
    this.title = parcel.readString();
    this.url = new URL(parcel.readString());
    this.contentType = parcel.readString();
    this.thumbnail = parcel.readParcelable(Bitmap.class.getClassLoader());
    this.resolution = parcel.readString();
    this.bandwidth = parcel.readString();
}

/* ... */

@Override
public int describeContents() {
    return 0;
}

@Override
public void writeToParcel(Parcel dest, int flags) {
    dest.writeString(duration);
    dest.writeString(title);
    dest.writeString(url.toString());
    dest.writeString(contentType);
    dest.writeValue(thumbnail);
    dest.writeString(resolution);
    dest.writeString(bandwidth);
}

public static final Parcelable.Creator CREATOR = new Parcelable.Creator() {
    public Media createFromParcel(Parcel in) {
        try {
            return new Media(in);
        } catch (MalformedURLException e) {
            e.printStackTrace();
            return null;
        }
    }

    public Media[] newArray(int size) {
        return new Media[size];
    }
};
}

充气异常在此阵列适配器中发生：

public class VideoPickerArrayAdapter extends ArrayAdapter<Media> {
public VideoPickerArrayAdapter(Context context, int resource, List<Media> items) {
    super(context, resource, items);
}

private class ViewHolder {
    ImageView imageView;
    TextView txtResolution;
    TextView txtDuration;
    Button btShare;
}

@Override
public View getView(int position, View convertView, ViewGroup parent) {
    ViewHolder holder = null;
    final Media media = getItem(position);

    LayoutInflater mInflater = (LayoutInflater) getContext().getSystemService(Activity.LAYOUT_INFLATER_SERVICE);

    if (convertView == null) {
        convertView = mInflater.inflate(R.layout.video_picker_list_item, null);
        holder = new ViewHolder();
        holder.imageView = (ImageView) convertView.findViewById(R.id.itemicon);
        holder.txtResolution = (TextView) convertView.findViewById(R.id.itemresolution);
        holder.txtDuration = (TextView) convertView.findViewById(R.id.itemduration);
        holder.btShare = (Button) convertView.findViewById(R.id.ShareButton);
        convertView.setTag(holder);
    } else
        holder = (ViewHolder) convertView.getTag();

    holder.txtResolution.setText(media.getResolution() + "p@" + media.getBandwidth() + " Mb/s");
    holder.txtDuration.setText(media.getDurationString());
    holder.imageView.setImageBitmap(media.getThumbnail());

    /* Share button */
    holder.btShare.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            Intent shareIntent = new Intent();
            shareIntent.setAction(Intent.ACTION_SEND);
            shareIntent.putExtra(Intent.EXTRA_STREAM, Uri.parse(media.getUrl().toString()));
            shareIntent.setType("video/mp4");
            getContext().startActivity(Intent.createChooser(shareIntent, "Share to"));
        }
    });

    return convertView;
}

公共类VideoPickerArrayAdapter扩展了ArrayAdapter{
公共VideoPickerArrayAdapter（上下文上下文、int资源、列表项）{
超级（上下文、资源、项目）；
}
私有类视窗持有者{

TextView txtResolution；

}

}
});
返回视图；
}

listview的XML布局（video\u picker\u list\u item.XML）如下所示，请注意stacktrace中提到的第38行是Share按钮

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"

在将媒体类打包之前，我不会在每次打开对话框时都出现充气异常，但它似乎仍然会随机出现，就像我在列表中添加一些媒体然后打开对话框时一样。我知道，一旦我能够显示列表，充气异常就不会发生，即使我关闭并打开了列表再次打开对话框，除非我更改了它的内容。但是，在我按下共享按钮3秒钟后，应用程序仍然会崩溃，出现类似“无法封送”的异常Media@fdsg94934'我试图通过使媒体可打包来修复此错误，但现在每次尝试打开对话框时都会遇到充气异常

我希望经验更丰富的Android开发人员能够理解这些东西是如何协同工作的。

似乎与应用程序兼容性有关。也许这个问题会有所帮助。在单击侦听器中调用getContext（）可能需要调用getSupportActionBar（）。getThemedContext（）？使用调试器进行调试应该可以帮助您了解您到底在哪里运行。@JJF谢谢！我今天早些时候读过同样的问题，但没有回答。切换到主题上下文后，工厂已经安装的错误仍然存在，但是通货膨胀例外情况消失了。共享按钮的样式已更改为黑色和黑色所有的文本视图似乎都是不可见的。但我很高兴错误得到了修复。有点离题，但这只是我的问题，还是API有时过于复杂了？我的意思是，我该如何将依赖于另一个类的序列化的膨胀错误与ActionBar的主题上下文联系起来，而ActionBar的主题上下文甚至与对话框没有任何关系？
