1. 通过intent来传递: activity1中设置 : A.传字符等: Java代码 String text = "hello"; Intent intent1 = new Intent(ActivityMain.this, Activity2.class); intent1.putExtra("activity1", text); startActivity(intent1); B. 传对象,对象要实例化,继承Serializable Java代码 Bundle mbundle=new Bundle(); mbundle.putSerializable("user",userList.get(position)); Intent in =new Intent (getApplicationContext(), activity2.class); in.putExtras(mbundle); startActivity(in); activity2中接收: A:接收 Java代码 Bundle extras = getIntent().getExtras(); if (extras != null) { textview.setText(extras.getString("activity1")); } B.接收 Java代码 Bundle bundel = getIntent().getExtras(); user= (User) bundel.get("user"); 2. SharedPreferences 在activity1中设置的如下: Java代码 SharedPreferences sp = getSharedPreferences("textinfo",0); Editor editor = sp.edit(); String text = "hello"; editor.putString("text", text); editor.commit(); Intent i = new Intent(getApplicationContext(),activity2.class); startActivity(i); 跳转到Message的activity,获取内容如下 Java代码 SharedPreferences share = getSharedPreferences("textinfo",0); String text = share.getString("text", null); msgtextview.setText(text);
