SharedPreference

保存

 public void save(View view){    sharedPreferences=getSharedPreferences("data", MODE_PRIVATE);    Editor editor=sharedPreferences.edit();    editor.putString("name", "柳树");    editor.putInt("age", 20);    editor.putBoolean("isMarried", false);    editor.commit();        }    

输出

public void restore(View view){    String name=sharedPreferences.getString("name", null);    int age=sharedPreferences.getInt("age", 0);    boolean isMarried=sharedPreferences.getBoolean("isMarried", false);    Log.d("MainActivity", "name"+name+"\nage"+age+"\nisMarried"+isMarried);    }

第一次就这样吧.
