android SharedPreferences

一、寫入

SharedPreferences perference = getSharedPreferences("ServerAccess", Context.MODE_PRIVATE);

Editor editor = perference.edit();

editor.putString("name", "zj");

editor.commit();//未調用commit前，資料實際是沒有存儲進檔案中的。 調用後，存儲存儲

Toast.makeText(ServerAccessActivity.this, "寫入成功", Toast.LENGTH_LONG).show();

二、讀取

SharedPreferences perference2 = getSharedPreferences("ServerAccess", Context.MODE_PRIVATE);

String returnStr = perference2.getString("name", "no");

Toast.makeText(this, returnStr, Toast.LENGTH_LONG).show();
