Intent intent = new Intent();
//作为接受数据端
intent.setClass(Activity1.this, Activity2.class);
startActivityForResult(intent, RG_REQUEST);
/////////////////////

//处理接收的数据

//接收数据
Bundle bundle =data.getExtras();
double aplpa=bundle.getDouble("aplpa");

}

Activity2
复制代码 代码如下:
// //////////////////
// 点击按键后，确认返回处理
// ////////////
