Question

如何使用 Bundle 传递数据

Answer 1

Book类：
package com.bundletest.model.fneg;

import java.io.Serializable;

/**

*/
public class Book implements Serializable {
/**
*
*/
private static final long serialVersionUID = 1L;

private String name;
private String id;
private String author;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
public String getAuthor() {
return author;
}
public void setAuthor(String author) {
this.author = author;
}

}

实例化Book类，得到Book对象book以及设置成员变量：
if(TextUtils.isEmpty(bookName)||TextUtils.isEmpty(author)||TextUtils.isEmpty(id)){
Toast.makeText(AndroidBundleActivity.this, "输入框不能为空", Toast.LENGTH_SHORT).show();
}else{
Book book=new Book();
book.setName(bookName);
book.setAuthor(author);
book.setId(id);
Intent intent=new Intent(AndroidBundleActivity.this,RecieveActivity.class);
Bundle bundle=new Bundle();
bundle.putSerializable("book", book);
intent.putExtras(bundle);
startActivity(intent);
}

在另一个Activity中获取传递过来的book对象，并显示：
Intent intent=this.getIntent();
Bundle bundle=intent.getExtras();

Book book=(Book)bundle.getSerializable("book");
nameText.setText("书名："+book.getName());
authorText.setText("作者："+book.getAuthor());
idText.setText("ID:"+book.getId());
