ANDROID笔记:Activity之间的传值

Intent intent = new Intent(MyActivity.this, MyResultActivity.class);
// 调用返回
startActivityForResult(intent, 1);

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);

// String nameString = data.getStringExtra("name");
// String sexString = data.getStringExtra("sex");
// 获取Person对象
Person person = (Person) data.getSerializableExtra("person");
if (person != null) {
String name = person.getName();
String sexString = person.getSex();
Toast.makeText(getApplicationContext(), name + "---" + sexString,
Toast.LENGTH_SHORT).show();
}

}

Intent intent = new Intent(MyResultActivity.this, MyActivity.class);
// intent.putExtra("name", "eve");
// intent.putExtra("sex", "man");
// 返回对象
Person person = new Person("eve", "man");
intent.putExtra("person", person);
// 返回数据
setResult(1, intent);
finish();
