AndroidIntent传递类，数组的两种方法

使用环境：

需要跳转界面传递数据

使用方法：

 intent传递类：

第一种： 序列化之后传递

类序列化：（遇到class  就 implements Serializable）

public class RectifyInfo implements Serializable{}

开始传递：

Intent intent = new Intent(getActivity(),RectificationIssuedActivity.class);Bundle bundle = new Bundle();bundle.putSerializable("rect",mLists.get(position));//传入类的对象intent.putExtras(bundle);getActivity().startActivity(intent);

取出数据：

rr = (RectifyInfo.ResultBean) getIntent().getSerializableExtra("rect");

第二种

用Parcelable方式传递Object

让bean类集成parcelable（用法请百度）

public class QualityInfo implements Parcelable{    public QualityInfo(){    }    private String inspectionAbbreviation;//private String 组砌方法private String ,    private String inspectionComments;//private String private String ,    private String inspectionGrade;//private String 1private String ,    private String inspectionId;//private String c529c9acb65e43b2a232a5cde3892f14private String ,    private String inspectionStandardAb;//private String 第5.3.1条private String ,    private String inspectionStandardall;//private String private String ,    private String inspectionType;//private String 一般项目private String ,    private String inspectionValid;//private String 0private String ,    private String itemId;//private String bfcb91b91a294e718a234f5241f69663private String    //取出    protected QualityInfo(Parcel in) {        inspectionAbbreviation = in.readString();        inspectionComments = in.readString();        inspectionGrade = in.readString();        inspectionId = in.readString();        inspectionStandardAb = in.readString();        inspectionStandardall = in.readString();        inspectionType = in.readString();        inspectionValid = in.readString();        itemId = in.readString();    }    public static final Creator<QualityInfo> CREATOR = new Creator<QualityInfo>() {        @Override        public QualityInfo createFromParcel(Parcel in) {            return new QualityInfo(in);        }        @Override        public QualityInfo[] newArray(int size) {            return new QualityInfo[size];        }    };    public String getInspectionAbbreviation() {        return inspectionAbbreviation;    }    public void setInspectionAbbreviation(String inspectionAbbreviation) {        this.inspectionAbbreviation = inspectionAbbreviation;    }    public String getInspectionComments() {        return inspectionComments;    }    public void setInspectionComments(String inspectionComments) {        this.inspectionComments = inspectionComments;    }    public String getInspectionGrade() {        return inspectionGrade;    }    public void setInspectionGrade(String inspectionGrade) {        this.inspectionGrade = inspectionGrade;    }    public String getInspectionId() {        return inspectionId;    }    public void setInspectionId(String inspectionId) {        this.inspectionId = inspectionId;    }    public String getInspectionStandardAb() {        return inspectionStandardAb;    }    public void setInspectionStandardAb(String inspectionStandardAb) {        this.inspectionStandardAb = inspectionStandardAb;    }    public String getInspectionStandardall() {        return inspectionStandardall;    }    public void setInspectionStandardall(String inspectionStandardall) {        this.inspectionStandardall = inspectionStandardall;    }    public String getInspectionType() {        return inspectionType;    }    public void setInspectionType(String inspectionType) {        this.inspectionType = inspectionType;    }    public String getInspectionValid() {        return inspectionValid;    }    public void setInspectionValid(String inspectionValid) {        this.inspectionValid = inspectionValid;    }    public String getItemId() {        return itemId;    }    public void setItemId(String itemId) {        this.itemId = itemId;    }    //这个方法不需要修改    @Override    public int describeContents() {        return 0;    }    //写入    @Override    public void writeToParcel(Parcel parcel, int i) {        parcel.writeString(inspectionAbbreviation);        parcel.writeString(inspectionComments);        parcel.writeString(inspectionGrade);        parcel.writeString(inspectionId);        parcel.writeString(inspectionStandardAb);        parcel.writeString(inspectionStandardall);        parcel.writeString(inspectionType);        parcel.writeString(inspectionValid);        parcel.writeString(itemId);    }

开始传递：

（这一种需要做的代码比implements Ser………做的工作稍微多了一点点，但是方法更显得独一无二）

ParInfo parInfo = new ParInfo(name, website, weibo);Intent intent = new Intent();Bundle bundle = new Bundle();bundle.putParcelable("parinfo", parInfo);// 这里调用了writeToParcel方法，向dest写数据  intent.setClass(MainActivity.this, ResultActivity.class);intent.putExtras(bundle);startActivity(intent);

取出数据：

ParInfo parInfo = (ParInfo) getIntent().getParcelableExtra("parinfo");//这里调用了UsercreateFromParcel方法，返回

**********************************************************************************************************

分割线，下面再Activity中传递数组     序列

ArrayList<SerInfo> listObj = new ArrayList<SerInfo>();SerInfo serInfo1 = new SerInfo(name, website, weibo);SerInfo serInfo2 = new SerInfo(name, website, weibo);listObj.add(serInfo1);listObj.add(serInfo2);Intent intent = new Intent();intent.setClass(MainActivity.this, ResultActivity.class);intent.putExtra("listobj", (Serializable) listObj);  
startActivity(intent);

取值的方法：

SerInfo serInfo = (SerInfo) getIntent().getSerializableExtra("listobj"); 

***********************************************************************************************************************************

Activity和fragment传递数据：

 传递基本类型数据：

Fragment fragment1 = new RectifySecondFragment();Bundle bundle1 = new Bundle();bundle1.putString(BUNDLE_STR,"待下发");fragment1.setArguments(bundle1);

取出方法：

String argument = getArguments().getString(BUNDLE_STR);

传递数组：

Fragment fragment = new RectifyFragment();Bundle b1 = new Bundle();if (0 == position) {    LogUtil.e("activity传值："+ rr.size() + "条");    b1.putSerializable(INTENTN_MODEL, (Serializable) list0);} else if (1 == position) {    LogUtil.e("activity传值："+ rr.size() + "条");    b1.putSerializable(INTENTN_MODEL, (Serializable) list1);}b1.putInt(INTENTN_ID, position);fragment.setArguments(b1);

取出：

mLists = (List<RectifyInfo.ResultBean>) getArguments().getSerializable(INTENTN_MODEL);

int i = getArguments().getInt(INTENTN_ID);

总结：

  1 bean类序列化以后，可以存类和列表。

2 通过intent存取和通过arguments存取方法差不多。
