在两种情况下，只有一种情况会给我这个唯一的错误。我基本上都是按照android教程中的每一个字符来操作的，而且出于某种原因，它只在特定的区域工作。
Intent shareIntent = new Intent();
shareIntent.setAction(Intent.ACTION_SEND);
shareIntent.putExtra(Intent.EXTRA_TEXT, getSharedNutritionText(mMultiSelector.getSelectedPositions()));
shareIntent.setType("text/plain");
startActivity(shareIntent);
出现以下错误：

而在我的另一个（几乎）相同的片段中，我有以下代码：
Intent shareIntent = new Intent();
shareIntent.setAction(Intent.ACTION_SEND);
shareIntent.putExtra(Intent.EXTRA_TEXT, getSharedLabelText(mMultiSelector.getSelectedPositions()));
shareIntent.setType("text/plain");
startActivity(shareIntent);
这是我的营养信息课
public class NutritionInfo extends SugarRecord<NutritionInfo> {
public String nutritionName;
public String nutritionHeaderTitle;
public int nutritionCalories;
public boolean nutritionArchived;
public boolean nutritionChecked;
public NutritionInfo () {}
public NutritionInfo (String name, String headerTitle, int cal, boolean isArchived, boolean isChecked) {
nutritionName = name;
nutritionHeaderTitle = headerTitle;
nutritionCalories = cal;
nutritionArchived = isArchived;
nutritionChecked = isChecked;
}
}
这是我的营养强化剂：
public class NutritionDisplayFragment extends BaseFragment implements ActionMode.Callback {
private String getSharedNutritionText(List<Integer> positions) {
String shareText;
if (positions.equals(null)) {
shareText = "";
} else {
shareText = "Food and carbs:\n";
for (int go = 0; go < positions.size(); go++) {
shareText = shareText +
nutritionList.get(go).nutritionTitle + " - \t" +
nutritionList.get(go).nutritionCarbs + "\n";
}
}
return shareText;
} ( . . . )
}
对比我的标签：
public class LabelManagerFragment extends BaseFragment implements ActionMode.Callback {
private String getSharedLabelText(List<Integer> positions) {
String shareText = "";
if (positions.equals(null)) {
shareText = "";
} else {
for (int go = 0; go < positions.size(); go++) {
shareText = shareText +
labelList.get(go).labelName + "\t" +
labelList.get(go).labelYear + "\n";
}
}
return shareText;
} ( . . . )
}
这不会产生运行时错误。两个get（）方法都返回一个简单的字符串。为什么第一个错误会抱怨“com.package.nutritioninfo@84055e1”，它甚至不是要共享的数据类型，因为它是不可封送处理的，而另一个则毫无障碍地共享字符串？
为了进一步说明：我在where the method is（通常返回一个简单的
"hello world"的方法）中尝试了硬编码String，但遇到了同样的问题。 最佳答案
实现Parcelable接口，如下所示：
public class NutritionInfo extends SugarRecord<NutritionInfo> implements Parcelable {
public String nutritionName;
public String nutritionHeaderTitle;
public int nutritionCalories;
public boolean nutritionArchived;
public boolean nutritionChecked;
public NutritionInfo() {
}
public NutritionInfo(String name, String headerTitle, int cal, boolean isArchived, boolean isChecked) {
nutritionName = name;
nutritionHeaderTitle = headerTitle;
nutritionCalories = cal;
nutritionArchived = isArchived;
nutritionChecked = isChecked;
}
protected NutritionInfo(Parcel in) {
nutritionName = (String) in.readValue(null);
nutritionHeaderTitle = (String) in.readValue(null);
nutritionCalories = in.readInt();
nutritionArchived = in.readByte() != 0;
nutritionChecked = in.readByte() != 0;
}
public static final Creator<NutritionInfo> CREATOR = new Creator<NutritionInfo>() {
@Override
public NutritionInfo createFromParcel(Parcel in) {
return new NutritionInfo(in);
}
@Override
public NutritionInfo[] newArray(int size) {
return new NutritionInfo[size];
}
};
@Override
public int describeContents() {
return 0;
}
@Override
public void writeToParcel(Parcel dest, int flags) {
dest.writeValue(nutritionName);
dest.writeValue(nutritionHeaderTitle);
dest.writeInt(nutritionCalories);
dest.writeByte((byte) (nutritionArchived ? 1 : 0));
dest.writeByte((byte) (nutritionChecked ? 1 : 0));
}
}
对你的糖分记录也一样。如果super类实现了parcelable，则无需在nutritioninfo中再次声明，只需实现这些内容。
