这是activityresult1

我如何将来自activityresult1的计算金额发送到activityresult2
static public String txtOrder ="";
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_activityresult2);
Bundle bundle = getIntent().getExtras();
String strfnq = bundle.getString("Noodle quantity");
String strfrq = bundle.getString("Rice quantity");
String strfsq = bundle.getString("Fish quantity");
String stricq = bundle.getString("Iced tea");
Integer strsum = bundle.getInt("sum");
boolean addNingc = bundle.getBoolean("ANI");
boolean addRingc = bundle.getBoolean("ARI");
boolean addFingc = bundle.getBoolean("AFI");
boolean addTingc = bundle.getBoolean("AIT");
// boolean addmoneyc = bundle.getBoolean("AMY");
Intent mIntent = getIntent();
int sum = mIntent.getIntExtra("sum",strsum);
TextView costtext = (TextView)findViewById(R.id.costtext);
costtext.setText(getIntent().getExtras().getString("sum"));
TextView foodorders = (TextView) findViewById(R.id.foodordershow);
foodorders.setText(getIntent().getExtras().getString("Quantity"));
String addNdlThing = "";
if (addNingc) {
addNdlThing = " with addition of ingredients";
}
String addRlThing = "";
if (addRingc) {
addRlThing = " with addition of ingredients";
}
String addSlThing = "";
if ( addFingc) {
addSlThing = " with addition of ingredients";
}
String addTeac = "";
if ( addTingc ) {
addTeac = " with addition of ingredients";
}
foodorders = (TextView) findViewById(R.id.foodordershow);
if(strfnq.equals("") && strfrq.equals("") && strfsq.equals("")&& stricq.equals("")){
txtOrder = "Sorry, You've not ordered any thing , please return to previous menu to order";
}else if (!strfnq.equals("") && !strfrq.equals("") && !strfsq.equals("")&& stricq.equals("")) {
txtOrder = "Thank you , You've ordered\n" + strfnq + " fried noodle" + addNdlThing +" and\n"+ strfrq
+ " fried rice" + addRlThing +" and\n" + strfsq + " Steam fish " + addSlThing + "and\n" + stricq + " Steam fish " + addTeac;
} else {
txtOrder = "Thank you , You've ordered\n";
if(!strfnq.equals("")){
txtOrder = txtOrder + strfnq + " fried noodle" + addNdlThing;
}
if(!strfrq.equals("")){
txtOrder = txtOrder + strfrq + " fried rice" + addRlThing;
}
if(!strfsq.equals("")){
txtOrder = txtOrder + strfsq + " Steam fish" + addSlThing;
}
if(!stricq.equals("")){
txtOrder = txtOrder + stricq + " Iced Tea"+ addTeac;
}
}
foodorders.setText(txtOrder);
}
我想计算在result1中花费的钱并将其显示在结果2中 我尝试过使用他们在底部写的方法，但它不起作用，因为我不知道该填写什么。请帮助我，我真的需要这方面的帮助，我打字很多，以便使字数计数，所以我可以发布，因为我有太多的代码，他们说，请不要不喜欢这篇文章，不要这样的人，像这样和它会为双方都感到高兴，问问题并不代表我是愚蠢的
答案 0 :(得分：0)
您可以将sum的值发送到下一个activity，并通过Bundle在另一个activity中获取，如下所示。认为您将其发送到activity B
Intent i= new Intent(this,B.class);
i.putExtra("sum",sum);
startActivity(i);
您可以通过以下任一context，activity B，this
getActivity()发送至getApplicationContext()
然后在activity B中，您可以在onCreate()方法中添加这些行，以获取传递的内容
Bundle MainActivityData= getIntent().getExtras();
int sum= MainActivityData.getString("sum");
