android传值

男儿欲遂平生志，六经勤向窗前读。这篇文章主要讲述android传值相关的知识，希望能为你提供帮助。
需求
OneActivity向TwoActivity传值name=hzs，然后TwoActivity向OneActivity传值sex=Y
第一步：OneActivity向TwoActivity传值name=hzs
OneActivity 里设置

Intent intent = new Intent(OneActivity.this,TwoActivity.class);
intent.putExtra("name","hzs");
startActivityForResult(intent,2008); //code是请求码 int类型

TwoActivity 里取值

Intent getIntent = getIntent();
String name = getIntent.getStringExtra("name");

第二步：TwoActivity向OneActivity传值sex=Y
TwoActivity 里设置

Intent intent = new Intent();
intent.putExtra("sex", "Y");
setResult(1, intent); //resultCode 为返回码用于区分从哪里返回。
finish();

【android传值】OneActivity 里取值

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
switch(requestCode){
case 2000:
if(resultCode==1){
String sex = data.getStringExtra("sex");
}
break;
default:
}

super.onActivityResult(requestCode, resultCode, data);
}
