写入配置信息
private static void writeConfiguration(Context context,
LocaleConfiguration configuration) {
DataOutputStream out = null;
try {
out = new DataOutputStream(context.openFileOutput(PREFERENCES,
MODE_PRIVATE));
out.writeUTF(configuration.locale);
out.writeInt(configuration.mcc);
out.writeInt(configuration.mnc);
out.flush();
} catch (FileNotFoundException e) {
// Ignore
} catch (IOException e) {
// noinspection ResultOfMethodCallIgnored
context.getFileStreamPath(PREFERENCES).delete();
} finally {
if (out != null) {
try {
out.close();
} catch (IOException e) {
// Ignore
}
}
}
}
2，读去程序配置信息
private static void readConfiguration(Context context,
LocaleConfiguration configuration) {
DataInputStream in = null;
try {
in = new DataInputStream(context.openFileInput(PREFERENCES));
configuration.locale = in.readUTF();
configuration.mcc = in.readInt();during-pregnancy
configuration.mnc = in.readInt();
} catch (FileNotFoundException e) {
// Ignore
} catch (IOException e) {
// Ignore
} finally {
if (in != null) {
try {
in.close();
} catch (IOException e) {
// Ignore
}
}
}
}
private static class LocaleConfiguration {
public String locale;
public int mcc = -1;
public int mnc = -1;
}
注意：
PREFERENCES代表的是String 类型的一个记录信息的文件名：
private static final String PREFERENCES = "launcher.preferences";
