Android开发——Intent传递自定义类

Android开发——Intent传递自定义类

---

• 自定义类

public class People implements Serializable(){
	private String name;
	private int age;

	//构造器
	public People(){}

	public People( String name, int age ){
		this.name = name;
		this.age = age;
	}

	public String getName(){ return this.name; }
	public int getAge(){ return this.age; }
}

• MainActivity

//传递对象的Active
public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
		
		//实例化对象
		People p1 = new People( "Alan", 19 );
	
		//创建intent
		Intent intent = new Intent( MainActivity.this, SecondActivity.class );
		intent.put( "theOne", p1 );  //类似于Servlet中的session，根据键值对存放数据
		startActivity( intent );
    }
}

• SecondActivity

//接收对象的Active
public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
		
		//实例化对象
		People p1 = new People();
	
		//获取intent
		Intent intent = getIntent();
		
		//获取传递的对象
		p1 = (People)intent.getSerializableExtra("theOne");
    }
}
