Android Properties 使用实例

Android应用开发的过程中有的时候我们可能会用到.properties文件来写一些配置信息(例如服务器的IP，端口号，APP应用更新的URL等等)。下面就对Android 应用中操作Properties文件做一个简单的封装(没什么技术含量) .properties文件放置在assetes文件夹下面。

简单的类图如下

这里写图片描述

主要的操作都在BasePropertiesConfig文件中完成，代码如下

public abstract class BasePropertiesConfig implements BasePropertiesControl {    private final Properties mProps = new Properties();    protected abstract Context getContext();    protected abstract String getPropertyFileName();    protected BasePropertiesConfig() {        initialize();    }    private void initialize() {        Context context = getContext();        InputStream in = null;        try {            AssetManager assetManager = context.getAssets();            in = assetManager.open(getPropertyFileName());            mProps.load(in);        } catch (IOException e) {            Log.e("BasePropertiesConfig", "Cannot open: " + getPropertyFileName());        } finally {            if (in != null) {                try {                    in.close();                } catch (IOException ignored) {                }            }        }    }    @Override    public boolean getBoolean(String key) {        return getBoolean(key, false);    }    @Override    public boolean getBoolean(String key, boolean defVal) {        return Boolean.parseBoolean(mProps.getProperty(key, Boolean.toString(defVal)));    }    @Override    public int getInteger(String key) {        return getInteger(key, 0);    }    @Override    public int getInteger(String key, int defVal) {        return Integer.parseInt(mProps.getProperty(key, Integer.toString(defVal)));    }    @Override    public short getShort(String key) {        return getShort(key, 0);    }    @Override    public short getShort(String key, int defVal) {        return Short.parseShort(mProps.getProperty(key, Integer.toString(defVal)));    }    @Override    public long getLong(String key) {        return getLong(key, 0);    }    @Override    public long getLong(String key, int defVal) {        return Long.parseLong(mProps.getProperty(key, Integer.toString(defVal)));    }    @Override    public String getString(String key) {        return mProps.getProperty(key);    }    @Override    public String getString(String key, String defVal) {        return mProps.getProperty(key, defVal);    }}

顺带附上一个实例(很简单的很简单的)
