通过意向传递的JSONObject到另一个活动 [英] Passing JSONObject to another activity via Intent
问题描述
我知道如何处理方法jsonObj.toString()做的,但我有一个理由不能这样做。我的JSONObject有一个JSONArray里面有太多的数据,所以如果我将其转换为字符串,然后转换回来,我害怕它到达字符串类型的限制。
所以,我想通过一个纯粹的对象,而不是使用该方法。我实现Parcelable接口,这样做,但我得到了错误了java.lang.RuntimeException:包裹:不能编组值
公共类MJSONObject实现Parcelable {
私人的JSONObject的JSONObject;公共MJSONObject(){
}公共MJSONObject(的JSONObject的JSONObject){
this.jsonObject =的JSONObject;
}公共无效集(的JSONObject的JSONObject){
this.jsonObject =的JSONObject;
}公众的JSONObject得到(){
返回的JSONObject;
}@覆盖
公众诠释describeContents(){
// TODO自动生成方法存根
返回0;
}公共静态最终Parcelable.Creator< MJSONObject> CREATOR =新Parcelable.Creator< MJSONObject>(){
公共MJSONObject createFromParcel(包裹中){
返回新MJSONObject(中);
} 公共MJSONObject [] newArray(INT大小){
返回新MJSONObject【尺寸】;
}
};@覆盖
公共无效writeToParcel(DEST包裹,INT标志){
dest.writeValue(JSONObject的);
}私人MJSONObject(包裹中){
JSONObject的=(的JSONObject)in.readValue(JSONObject.class.getClassLoader());
}
您可以很容易地通过字符串$转换它传递你的
的JSONObject
C $ C>像在某些情况下,我们通过追加它作为一个字符串发送
。因此,尝试把它发送为的JSONObject
与网址字符串
这样的:
intent.putExtra(JSONObject的jsonObject.toString());
和接收它的另一面。
意向意图= getIntent();串jsonString = intent.getStringExtra(JSONObject的);
现在你有你的 JSON
在字符串
名为 jsonString
假设它当从Web服务接收到你喜欢的响应,然后让你的的JSONObject
这样的:
的JSONObject jObj =新的JSONObject(jsonString);
希望你能明白我的观点是:)
I know what to do with the method jsonObj.toString() but I have a reason to can not do so. My JSONObject has a JSONArray inside that has too much data, so If I convert it to String then transform back that I afraid of it reaches the limit of String type. So I want to pass a pure object rather than use that method. I implement Parcelable interface to do that but I got the error "java.lang.RuntimeException: Parcel: unable to marshal value"
public class MJSONObject implements Parcelable {
private JSONObject jsonObject;
public MJSONObject() {
}
public MJSONObject(JSONObject jsonObject) {
this.jsonObject = jsonObject;
}
public void set(JSONObject jsonObject) {
this.jsonObject = jsonObject;
}
public JSONObject get() {
return jsonObject;
}
@Override
public int describeContents() {
// TODO Auto-generated method stub
return 0;
}
public static final Parcelable.Creator<MJSONObject> CREATOR = new Parcelable.Creator<MJSONObject>() {
public MJSONObject createFromParcel(Parcel in) {
return new MJSONObject(in);
}
public MJSONObject[] newArray(int size) {
return new MJSONObject[size];
}
};
@Override
public void writeToParcel(Parcel dest, int flags) {
dest.writeValue(jsonObject);
}
private MJSONObject(Parcel in) {
jsonObject = (JSONObject) in.readValue(JSONObject.class.getClassLoader());
}
You can easily pass your JSONObject
by converting it in String
like in some scenarios we send JSONObject
with url by appending it as a String
. So, Try to send it as String
like:
intent.putExtra("jsonObject", jsonObject.toString());
And receive it on other side
Intent intent = getIntent();
String jsonString = intent.getStringExtra("jsonObject");
Now you have your JSON
in a String
named jsonString
assume it as a response like when you received from Web Service and then get your JSONObject
like:
JSONObject jObj = new JSONObject(jsonString);
hope you will understand what my point is :)
