Question

我想将ArrayList<NameValuePair> nameValuePairs个活动传递给另一个活动。我为此写了parcelable class。

Parcelable Class:

/**Getters/Setters have been removed to make reading easier*//

    public class BasicNameValuePair  implements Parcelable {
        private String name;
        private String value;



     public BasicNameValuePair(String name, String value){
            this.name = name;
            this.value = value;
        }

        protected BasicNameValuePair(Parcel in) {
            name = in.readString();
            value = in.readString();
        }

        @Override
        public void writeToParcel(Parcel dest, int flags) {
            dest.writeString(name);
            dest.writeString(value);
        }

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

        public static final Creator<BasicNameValuePair> CREATOR = new Creator<BasicNameValuePair>() {
            @Override
            public BasicNameValuePair createFromParcel(Parcel in) {
                return new BasicNameValuePair(in);
            }

            @Override
            public BasicNameValuePair[] newArray(int size) {
                return new BasicNameValuePair[size];
            }
        };
    }

我发送数据的第一个活动：

ArrayList<com.example.ss.myapplication.BasicNameValuePair> nameValuePairs;
        nameValuePairs = new ArrayList<com.example.ss.myapplication.BasicNameValuePair>();
        nameValuePairs.add(new com.example.ss.myapplication.BasicNameValuePair("name",value));
        nameValuePairs.add(new com.example.ss.myapplication.BasicNameValuePair("name1", value1));

Intent intent = new Intent(MainActivity.this,Main2Activity.class);
                intent.putParcelableArrayListExtra("extraextra", nameValuePairs);
                startActivity(intent);

在我的第二个获得nameValuePair

的活动中

 ArrayList<com.example.ss.myapplication.BasicNameValuePair> testing = this.getIntent().getParcelableArrayListExtra("extraextra");


 for (com.example.ss.myapplication.BasicNameValuePair n : testing) {
            String name = n.getName();
            String value = n.getValue();
            System.out.print("name" + name + "value:" + value);
        }

但是，当我想添加数据nameValuePairs时，我收到错误。

BasicNameValuePair(android.os.Parcel) in BasicNameValuePair cannot be applied  to (java.lang.String, java.lang.String)

我应该如何更改BasicNameValuePair类？

中没有getname和getvalue

public class BasicNameValuePair  implements Parcelable {
    private String name;
    private String value;

    public String getName() {
        return name;
    }

    public String getValue() {
        return value;
    }

nameValuePair的parcelable类？
