Android(安卓)Intent传递对象

16lz 2022-05-14

Android中Intent中如何传递对象,就我目前所知道的有两种方法，一种是Bundle.putSerializable(Key,Object);另一种是Bundle.putParcelable(Key, Object);

本文只介绍好用的Serializable方法，想知道更多请自行百度。

第一步：新建一个类一个是Person.java实现Serializable接口

Person.java:

[java] view plain copy

packagecom.tutor.objecttran;
importjava.io.Serializable;
publicclassPersonimplementsSerializable{
privatestaticfinallongserialVersionUID=-7060210544600464481L;
privateStringname;
privateintage;
publicStringgetName(){
returnname;
}
publicvoidsetName(Stringname){
this.name=name;
}
publicintgetAge(){
returnage;
}
publicvoidsetAge(intage){
this.age=age;
}
}

第二步：发送对象

ObjectTranDemo.java:

[java] view plain copy

packagecom.tutor.objecttran;
importandroid.app.Activity;
importandroid.content.Intent;
importandroid.os.Bundle;
importandroid.view.View;
importandroid.view.View.OnClickListener;
importandroid.widget.Button;
publicclassObjectTranDemoextendsActivityimplementsOnClickListener{
privateButtonsButton,pButton;
publicfinalstaticStringSER_KEY="anystring";
publicvoidonCreate(BundlesavedInstanceState){
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
setupViews();
}
//我的一贯作风呵呵
publicvoidsetupViews(){
sButton=(Button)findViewById(R.id.button1);
sButton.setOnClickListener(this);
}
//Serializeable传递对象的方法
publicvoidSerializeMethod(){
PersonmPerson=newPerson();
mPerson.setName("H3c");
mPerson.setAge(23);
IntentmIntent=newIntent(this,ObjectTranDemo1.class);
BundlemBundle=newBundle();
mBundle.putSerializable(SER_KEY,mPerson);
mIntent.putExtras(mBundle);
startActivity(mIntent);
}
//铵钮点击事件响应
publicvoidonClick(Viewv){
SerializeMethod();
}
}

第三步：接收对象

ObjectTranDemo1.java:

[java] view plain copy

packagecom.tutor.objecttran;
importandroid.app.Activity;
importandroid.os.Bundle;
importandroid.widget.TextView;
publicclassObjectTranDemo1extendsActivity{
@Override
publicvoidonCreate(BundlesavedInstanceState){
super.onCreate(savedInstanceState);
TextViewmTextView=newTextView(this);
PersonmPerson=(Person)getIntent().getSerializableExtra(ObjectTranDemo.SER_KEY);
mTextView.setText("Younameis:"+mPerson.getName()+"/n"+
"Youageis:"+mPerson.getAge());
setContentView(mTextView);
}
}
