android学习记录-activity跳转

直接跳转

startActivity(new Intent (CurrentActivity.this, TargetActivity.class) );  

要求返回结果的跳转

1、当前activity跳转

Intent intent = new Intent (CurrentActivity.this, TargetActivity.class)startActivityForResult (Intent intent, int requestCode)

2、目标activity处理

setResult(int resultCode) //返回结果//setResult(int resultCode, Intent data) 返回结果和数据finish()//注销后得以跳转回原activity，返回结果

3、当前activity处理返回结果

@Override protected void onActivityResult(int requestCode, int resultCode, Intent data) { }
