推荐答案

写入共享preferences

要写入共享preferences文件，通过调用编辑（）在您的共享preferences创建共享preferences.Editor。

To write to a shared preferences file, create a SharedPreferences.Editor by calling edit() on your SharedPreferences.

传递要与方法，如putInt（）和putString（）写入键和值。然后调用commit（）保存更改。例如：

Pass the keys and values you want to write with methods such as putInt() and putString(). Then call commit() to save the changes. For example:

SharedPreferences sharedPref = getActivity().getPreferences(Context.MODE_PRIVATE);
SharedPreferences.Editor editor = sharedPref.edit();
editor.putInt(getString(R.string.saved_high_score), newHighScore);
editor.commit();

从共享preferences阅读

要检索的共享preferences文件值，调用方法，如调用getInt（）和GetString（），提供关键你想要的值，和可选的默认值返回，如果该键不在present。例如：

To retrieve values from a shared preferences file, call methods such as getInt() and getString(), providing the key for the value you want, and optionally a default value to return if the key isn't present. For example:

SharedPreferences sharedPref = getActivity().getPreferences(Context.MODE_PRIVATE);
int defaultValue = getResources().getInteger(R.string.saved_high_score_default);
long highScore = sharedPref.getInt(getString(R.string.saved_high_score), defaultValue);
