在android中我们经常要在activity之间去传递数据，有时候会是一些比较简单，有时候又会是比较复杂的，今天这一篇主要是写如何在activity之间传递对象，废话不多说，直接上代码
MainActivity.java public class MainActivity extends Activity implements View.OnClickListener { private Button mButton; private Context mContext; private Personal mPersonal; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); mContext=this; mPersonal = new Personal(); mPersonal.setName("小明"); mPersonal.setAge(20); initView(); } //初始化View private void initView() { mButton = (Button) findViewById(R.id.btn); mButton.setOnClickListener(this); } @Override public void onClick(View v) { Intent intent = new Intent(mContext, SecondActivity.class); intent.putExtra("personal", mPersonal); startActivity(intent); } } SecondActivity.java public class SecondActivity extends Activity { private Personal mPersonal; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_second); mPersonal = (Personal) getIntent().getExtras().get("personal"); String info = mPersonal.getName() + "/" + mPersonal.getAge(); Toast.makeText(SecondActivity.this, "传递过来的数据为:" + info, Toast.LENGTH_SHORT).show(); } } Personal.java //该类是传递的对象类，需要实现序列化，不然无法实现activity之间传递对象 public class Personal implements Serializable { private String name; private int age; public String getName() { return name; } public void setName(String name) { this.name = name; } public int getAge() { return age; } public void setAge(int age) { this.age = age; } }
