Adnroid用Intent来做activity的跳转，轻量级的数据用Bundle 配合着传递。

传回数据用startActivityForResult来搞。

跳转时代码：

_Intent=new Intent();
_Intent.setClass(getBaseContext(), Appearance.class);
startActivityForResult(_Intent, 1);

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
// TODO Auto-generated method stub
Bundle _Bundle;
switch (requestCode) {
case 1:
if (resultCode == RESULT_OK)
{
_Bundle = data.getExtras();
String NAME= _Bundle.getString("NAME");
}
break;
default:
break;
}
}

另一个activity回传：

Intent _Intent = new Intent();
Bundle _Bundle = new Bundle();
_Bundle.putString("NAME","LINCYANG");
_Intent.putExtras(_Bundle);
Appearance.this.setResult(RESULT_OK,_Intent);
Appearance.this.finish();

就是这么简单～～～
