从第一个活动传递给第二个活动

Question

如何保存数据的意图我有Myactivity这是从以前的活动获得意图数据。意图数据通过活动的微调器发送。我想将这个Spinner的这个意图数据保存到Myactvity中。当我进入下一个活动的Myactivity through菜单选项时，意向数据应该保持不变。

Answer 1

在你第一次活动1

Intent myintent= new Intent(FirstActivity.this,SecondActivity.class); 
myintent.putExtra("Name", "your String"); 
startActivity(myintent); 

在第二活性2

Intent myintent = getIntent(); 

if(null!=myintent.getExtras()){ 
    String Name= myintent.getExtras().getString("Name");   
    Toast.makeText(getApplicationContext(),""+Name,12).show();        
}else{ 
    Toast.makeText(getApplicationContext(),"No Recor Here..",12).show(); 
} 

像SharedPreferences [2] 在你第一次ActivityA

Intent myintent= new Intent(FirstActivity.this,SecondActivity.class); 
SharedPreferences spref = this.getSharedPreferences("mynotifyid", MODE_WORLD_WRITEABLE); 
SharedPreferences.Editor spreedit = spref.edit(); 
spreedit.putString("Name1", str1.toString()); 
spreedit.putString("Name2", str2.toString()); 
spreedit.putString("Name3", str3.toString()); 
spreedit.putString("Name4", str4.toString()); 
spreedit.commit(); 
startActivity(myintent); 

在你的第二个ActivityB

SharedPreferences spref = context.getSharedPreferences("mynotifyid", Context.MODE_WORLD_WRITEABLE); 
String str1 = spref.getString("Name1",""); 
String str2 = spref.getString("Name2",""); 
String str3 = spref.getString("Name3",""); 
String str4 = spref.getString("Name4",""); 

为了保存对象的目的使用SharedPreferences
