//在按键按下后，调用第二个实体，第二个实体处理完数据后再传给第一个实体

btn3.setOnClickListener(new Button.OnClickListener() {

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

protected void onActivityResult(int requestCode,int resultCode,Intent data)

{

super.onActivityResult(requestCode, resultCode, data)

if(resultCode==RESULT_OK)

{

//接收数据

Bundle bundle =data.getExtras();

double aplpa=bundle.getDouble("aplpa");

String mode=bundle.getString("mode");

String time=bundle.getString("time");

}

}

Activity2

复制代码 代码如下:

// //////////////////

// 点击按键后，确认返回处理

// ////////////
