Android实用工具类-SharedPreferences

用了很多年了的SharedPreferences工具类，方便进行各种类型的数据存储和读写

import android.content.Context;import android.content.SharedPreferences;import android.content.SharedPreferences.Editor;import android.preference.PreferenceManager;public class ShareUtil {
       private Context mContext;    private String filename = null;    public ShareUtil(Context context) {        mContext = context;    }    public ShareUtil(Context context, String shareFile) {        mContext = context;        filename = shareFile;    }    private SharedPreferences getPreferences() {        if (filename == null) {            return PreferenceManager.getDefaultSharedPreferences(mContext);        } else {            return mContext.getSharedPreferences(filename, Context.MODE_PRIVATE);        }    }    private Editor getEditor() {        if (filename == null) {            return PreferenceManager.getDefaultSharedPreferences(mContext).edit();        } else {            return mContext.getSharedPreferences(filename, Context.MODE_PRIVATE).edit();        }    }    public boolean getBoolean(String key, boolean defValue) {        return getPreferences().getBoolean(key, defValue);    }    public float getFloat(String key, float defValue) {        return getPreferences().getFloat(key, defValue);    }    public int getInt(String key, int defValue) {        return getPreferences().getInt(key, defValue);    }    public long getLong(String key, long defValue) {        return getPreferences().getLong(key, defValue);    }    public String getString(String key, String defValue) {        return getPreferences().getString(key, defValue);    }    public boolean setShare(String key, boolean value) {        return getEditor().putBoolean(key, value).commit();    }    public boolean setShare(String key, float value) {        return getEditor().putFloat(key, value).commit();    }    public boolean setShare(String key, int value) {        return getEditor().putInt(key, value).commit();    }    public boolean setShare(String key, long value) {        return getEditor().putLong(key, value).commit();    }    public boolean setShare(String key, String value) {        return getEditor().putString(key, value).commit();    }    public void removeShare(String key) {        getEditor().remove(key).commit();    }}
