在Activity中传递对象（使用Parcelable方式）

参考文章
Android中如何使用Intent在Activity之间传递对象[使用Serializable或者Parcelable]
http://blog.csdn.net/cjjky/article/details/6441104

数据类型有限，比如遇到不可序列化的数据Bitmap,InputStream, 或者LinkList链表等等数据类型就不太好用。


要传递的对象

package com.andy.entity;  
  
package com.andy.entity;  
  
import android.os.Parcel;  
import android.os.Parcelable;  
  
public class Police implements Parcelable {  
      
    private String name;  
    private int workTime;  
  
    public String getName() {  
        return name;  
    }  
  
    public void setName(String name) {  
        this.name = name;  
    }  
  
    public int getWorkTime() {  
        return workTime;  
    }  
  
    public void setWorkTime(int workTime) {  
        this.workTime = workTime;  
    }  
      
    public static final Parcelable.Creator<Police> CREATOR = new Creator<Police>() {  
  
        @Override  
        public Police createFromParcel(Parcel source) {  
            Police police = new Police();  
            police.name = source.readString();  
            police.workTime = source.readInt();  
            return police;  
        }  
  
        @Override  
        public Police[] newArray(int size) {  
            return new Police[size];  
        }  
    };  
  
    @Override  
    public int describeContents() {  
        return 0;  
    }  
  
    @Override  
    public void writeToParcel(Parcel parcel, int flags) {  
        parcel.writeString(name);  
        parcel.writeInt(workTime);  
    }  
}  
      
   /** 
     * Pacelable传递对象方法  
     */  
    private void PacelableMethod(){  
        Police mPolice = new Police();     
        mPolice.setName("I am Police");        
        mPolice.setWorkTime(2008);     
        Intent mIntent = new Intent(this,ParcelableDemo.class);     
        Bundle mBundle = new Bundle();     
        mBundle.putParcelable(PAR_KEY, mPolice);     
        mIntent.putExtras(mBundle);     
       
        startActivity(mIntent);     
    }  
}  

接受对象的Activity

package com.andy.testdemo;  
  
import com.andy.entity.Police;  
  
import android.app.Activity;  
import android.os.Bundle;  
import android.widget.TextView;  
  
public class ParcelableDemo extends Activity {  
  
    @Override  
    public void onCreate(Bundle savedInstanceState) {  
        super.onCreate(savedInstanceState);  
          
        TextView mTextView = new TextView(this);     
        Police mPolice = (Police)getIntent().getParcelableExtra(TestActivity.PAR_KEY);     
        mTextView.setText("Police name is: " + mPolice.getName()+"/n"+     
                          "WorkTime is: " + mPolice.getWorkTime() + "/n");     
        setContentView(mTextView);     
    }  
  
}
