我利用后续类,这是我作为一个对象: http://pastebin.com/rKmtbDgF
和我想整个使用它传递:
意图书目=新的意向书(getBaseContext(),BookList.class);
束束=新包();
bundle.putParcelable(imageManager,(Parcelable)IM);
booklist.putExtras(包);
booklist.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
startActivity(书目);
和我想用接受它:
ImageManager IM =(ImageManager)getIntent()getExtras()getParcelable(imageManager)。
我收到以下错误:
java.lang.ClassCastException:com.example.example.ImageManager
解决方案
要做到这一点最简单的方法是实施可序列化。
的Bean;
@燮pressWarnings(串行)
公共类学生实现Serializable {
公益助学(INT年龄,字符串名称){
this.age =年龄;
this.name =名称;
}
公众诠释getAge(){
返回年龄;
}
公共无效setAge(INT岁){
this.age =年龄;
}
公共字符串的getName(){
返回this.name;
}
公共无效setname可以(字符串名称){
this.name =名称;
}
私人诠释年龄;
私人字符串名称;
}
发送的活动一个对象b活动
学生学生=新的学生(18,扎尔êAhmer);
意图I =新的意图(这一点,B.class);
i.putExtra(studentObject,学生);
startActivity(ⅰ);
获取对象在b活动。
意图I = getIntent();
学生学生=(学生)i.getSerializableExtra(studentObject);
I am utilizing the follow class, which I have as an object: http://pastebin.com/rKmtbDgF
And I am trying to pass it across using:
Intent booklist = new Intent(getBaseContext(), BookList.class);
Bundle bundle = new Bundle();
bundle.putParcelable("imageManager", (Parcelable) im);
booklist.putExtras(bundle);
booklist.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
startActivity(booklist);
And I am trying to receive it using:
ImageManager im = (ImageManager) getIntent().getExtras().getParcelable("imageManager");
I am getting the following error:
java.lang.ClassCastException: com.example.example.ImageManager
解决方案
Easiest Way to do this is to implement Serializeable ..
import java.io.Serializable;
@SuppressWarnings("serial")
public class Student implements Serializable {
public Student(int age, String name){
this.age = age;
this.name = name;
}
public int getAge() {
return age;
}
public void setAge(int age) {
this.age = age;
}
public String getName() {
return this.name;
}
public void setName(String name) {
this.name = name;
}
private int age;
private String name;
}
Sending object from Activity A to Activity B
Student student = new Student (18,"Zar E Ahmer");
Intent i = new Intent(this, B.class);
i.putExtra("studentObject", student);
startActivity(i);
Getting Object in Activity B.
Intent i = getIntent();
Student student = (Student)i.getSerializableExtra("studentObject");
