SharedPreferences的简单应用

private final String SHAREDNAME = "System";

private static final int CHBOXNUM = 5;

private boolean chboxState[] = new boolean[CHBOXNUM];

private String chboxString[] = new String[] { "C", "M", "P","B", "T" };

    public void readSettings() {

        SharedPreferences reading = getSharedPreferences(SHAREDNAME,
                Context.MODE_PRIVATE);
        for (int i = 0; i < CHBOXNUM; i++) {
            chboxState[i] = reading.getBoolean(chboxString[i], false);
        }
    }

    public void saveSettings() {
        SharedPreferences setting = getSharedPreferences(SHAREDNAME,
                Context.MODE_PRIVATE);
        Editor editor = setting.edit();

        for (int i = 0; i < CHBOXNUM; i++) {
            editor.putBoolean(chboxString[i], chboxState[i]);
        }
        editor.commit();
    }
