Question

在我的活动A 中，我想将results传递给活动B 。

ArrayList<SearchResults> results = new ArrayList<SearchResults>();

 i.putExtra("resuls", results);

活动B

 results=getIntent().getExtras().getString("results");

当想要 B

时，应用程序崩溃了

 Process: com.example.project.myapplication, PID: 3162
    java.lang.RuntimeException: Parcel: unable to marshal value com.example.project.myapplication.bean.SearchResults@f8e8031
            at android.os.Parcel.writeValue(Parcel.java:1397)
            at android.os.Parcel.writeList(Parcel.java:738)

信息搜索结果

public class SearchResults {

    private String weather = "";
    private String date = "";
    private String status = "";
    private String timeIn="";
    private String timeOut="";
    private String project="";
    private String description="";
    private String progress="";

    public void setWeather(String weather) {
        this.weather = weather;
    }

    public String getWeather() {
        return weather;
    }

    public void setDate(String date) {
        this.date = date;
    }

    public String getDate() {
        return date;
    }

    public void setStatus(String status) {
        this.status = status;
    }

    public String getStatus() {
        return status;
    }

    public void setTimeIn(String timeIn) {
        this.timeIn = timeIn;
    }

    public String getTimeIn() {
        return timeIn;
    }

    public void setTimeOut(String timeOut){
       this.timeOut=timeOut;
    }

    public String getTimeOut()
    {
        return timeOut;
    }

    public void setProject(String project){
        this.project=project;
    }

    public String getProject()
    {
        return project;
    }

    public void setProgress(String progress){
        this.progress=progress;
    }

    public String getProgress()
    {
        return progress;
    }

    public void setDescription(String description){
        this.description=description;
    }

    public String getDescription()
    {
        return description;
    }



}

如何传递数组并最终在活动B中显示它们？感谢

Answer 1

第1步：SearchResults实施Parcelable或Serializable。

步骤2：使用getParcelableArrayList()或getSerializable()代替getString()来检索附加内容Bundle中的值。

使用intent传递数组
