前言
今早起的还算早，看了一场NBA,一想到工作还没给答复，心里就有点着急了。中午定了份外卖，心酸的吃着土豆丝，好心酸，这时女朋友发来微信，说今晚我们去看我不是潘金莲吧！还记得在北京的时候这电影就一直在宣传，听到这个消息，心情好了那么点。把昨天整理的代码写篇文章平复一下糟糕的心情。今天带来了基本每个项目中都会使用的工具类。前方代码较多......

工具类
1、日志工具类
package com.example.dj.testdemo.Utils;
import com.example.dj.testdemo.BuildConfig;
/**
* 描述：日志工具类
* <p>
* 这个工具类主要在三处地方做了封装。
* 第一是加入BuildConfig.DEBUG判断，这样发布时就不会打印log，如果不了解BuildConfig，可以参考这篇文章Android BuildConfig.DEBUG的妙用
* 第二是log工具类都常见的，预设置TAG，这样不用每次都传两个参数
* 第三，通过StackTraceElement获取当前打印日志的类名和方法名，这个用来代替我们平时手写的TAG值。StackTrace用栈的形式保存了方法的调用信息。

public class MyLogger {
protected static final String TAG = "DSBBM";
public MyLogger() {
}
/**
* Send a VERBOSE log message.
*
* @param msg The message you would like logged.
*/
public static void v(String msg) {
if (BuildConfig.DEBUG)
android.util.Log.v(TAG, buildMessage(msg));
}
/**
* Send a VERBOSE log message and log the exception.
*
* @param msg The message you would like logged.
* @param tr An exception to log
*/
public static void v(String msg, Throwable tr) {
if (BuildConfig.DEBUG)
android.util.Log.v(TAG, buildMessage(msg), tr);
}
/**
* Send a DEBUG log message.
*
* @param msg
*/
public static void d(String msg) {
if (BuildConfig.DEBUG)
android.util.Log.d(TAG, buildMessage(msg));
}
/**
* Send a DEBUG log message and log the exception.
*
* @param msg The message you would like logged.
* @param tr An exception to log
*/
public static void d(String msg, Throwable tr) {
if (BuildConfig.DEBUG)
android.util.Log.d(TAG, buildMessage(msg), tr);
}
/**
* Send an INFO log message.
*
* @param msg The message you would like logged.
*/
public static void i(String msg) {
if (BuildConfig.DEBUG)
android.util.Log.i(TAG, buildMessage(msg));
}
/**
* Send a INFO log message and log the exception.
*
* @param msg The message you would like logged.
* @param tr An exception to log
*/
public static void i(String msg, Throwable tr) {
if (BuildConfig.DEBUG)
android.util.Log.i(TAG, buildMessage(msg), tr);
}
/**
* Send an ERROR log message.
*
* @param msg The message you would like logged.
*/
public static void e(String msg) {
if (BuildConfig.DEBUG)
android.util.Log.e(TAG, buildMessage(msg));
}
/**
* Send an ERROR log message and log the exception.
*
* @param msg The message you would like logged.
* @param tr An exception to log
*/
public static void e(String msg, Throwable tr) {
if (BuildConfig.DEBUG)
android.util.Log.e(TAG, buildMessage(msg), tr);
}
/**
* Send a WARN log message
*
* @param msg The message you would like logged.
*/
public static void w(String msg) {
if (BuildConfig.DEBUG)
android.util.Log.w(TAG, buildMessage(msg));
}
/**
* Send a WARN log message and log the exception.
*
* @param msg The message you would like logged.
* @param thr An exception to log
*/
public static void w(String msg, Throwable thr) {
if (BuildConfig.DEBUG)
android.util.Log.w(TAG, buildMessage(msg), thr);
}
/**
* Send an empty WARN log message and log the exception.
*
* @param thr An exception to log
*/
public static void w(Throwable thr) {
if (BuildConfig.DEBUG)
android.util.Log.w(TAG, buildMessage(""), thr);
}
protected static String buildMessage(String msg) {
//通过StackTraceElement获取当前打印日志的类名和方法名，这个用来代替我们平时手写的TAG值。
// StackTrace用栈的形式保存了方法的调用信息
StackTraceElement caller = new Throwable().fillInStackTrace().getStackTrace()[2];
return new StringBuilder().append(caller.getClassName()).append(".").append(caller.getMethodName()).append("(): ").append(msg).toString();
}
}
打印格式：I/DSBBM: com.example.dj.testdemo.MainActivity.onClick(): msg
这个工具类主要在三处地方做了封装。
第一是加入BuildConfig.DEBUG判断，这样发布时就不会打印log，如果不了解BuildConfig，可以参考这篇文章Android BuildConfig.DEBUG的妙用
第二是log工具类都常见的，预设置TAG，这样不用每次都传两个参数
第三是通过StackTraceElement获取当前打印日志的类名和方法名，这个用来代替我们平时手写的TAG值。StackTrace用栈的形式保存了方法的调用信息。对StackTrace不了解的同学可以参考这篇文章StackTrace简述以及StackTraceElement使用实例
2、Toast统一管理工具类
package com.example.dj.testdemo.Utils;
import android.content.Context;
import android.view.Gravity;
import android.widget.Toast;
/**
* 描述：统一管理类
* <p>
* Created by dj on 2016/11/17 0017.
*/
public class MyToast {
private MyToast() {
//不能被实例化
throw new UnsupportedOperationException("cannot be instantiated");
}
public static boolean isShow = true;
/**
* 屏幕中间位置显示短时间Toast
*
* @param context
* @param msg
*/
public static void ToastShortCenter(Context context, String msg) {
if (isShow) {
if (context != null) {
Toast toast = Toast.makeText(context, msg, Toast.LENGTH_SHORT);
toast.setGravity(Gravity.CENTER, 0, 0);
toast.show();
}
}
}
/**
* 屏幕中心位置长时间显示Toast
*
* @param context
* @param message
*/
public static void ToastLongCenter(Context context, String message) {
if (isShow) {
if (context != null) {
Toast toast = Toast.makeText(context, message, Toast.LENGTH_LONG);
toast.setGravity(Gravity.CENTER, 0, 0);
toast.show();
}
}
}
/**
* 自定义显示Toast时间
*
* @param context
* @param message
* @param duration
*/
public static void ToastShow(Context context, String message, int duration) {
if (isShow)
Toast.makeText(context, message, duration).show();
}
}
非常简单的一个封装类，短Toast、长Toast、自定义Toast的实现。
3、SharedPreferences封装工具类
package com.example.dj.testdemo.Utils;
import android.content.Context;
import android.content.SharedPreferences;
import java.lang.reflect.InvocationTargetException;
import java.lang.reflect.Method;
import java.util.Map;
/**
* 描述：SharedPreferences封装类
* <p>
* Created by dj on 2016/11/17 0017.
*/
public class SPUtils {
/**
* 保存在手机里面的文件名
*/
public static final String FILE_NAME = "share_data";
/**
* 保存数据的方法，我们需要拿到保存数据的具体类型，然后根据类型调用不同的保存方法
*
* @param context
* @param key
* @param object
*/
public static void put(Context context, String key, Object object) {
SharedPreferences sp = context.getSharedPreferences(FILE_NAME, Context.MODE_PRIVATE);
SharedPreferences.Editor editor = sp.edit();
if (object instanceof String) {
editor.putString(key, (String) object);
} else if (object instanceof Integer) {
editor.putInt(key, (Integer) object);
} else if (object instanceof Boolean) {
editor.putBoolean(key, (Boolean) object);
} else if (object instanceof Float) {
editor.putFloat(key, (Float) object);
} else if (object instanceof Long) {
editor.putLong(key, (Long) object);
} else {
editor.putString(key, object.toString());
}
/**
* commit操作使用了SharedPreferencesCompat.apply进行了替代，目的是尽可能的使用apply代替commit
* 因为commit方法是同步的，并且我们很多时候的commit操作都是UI线程中，毕竟是IO操作，尽可能异步；
*/
SharedPreferencesCompat.apply(editor);
}
/**
* 得到保存数据的方法，我们根据默认值得到保存的数据的具体类型，然后调用相对于的方法获取值
*
* @param context
* @param key
* @param defaultObject
* @return
*/
public static Object get(Context context, String key, Object defaultObject) {
SharedPreferences sp = context.getSharedPreferences(FILE_NAME, Context.MODE_PRIVATE);
if (defaultObject instanceof String) {
return sp.getString(key, (String) defaultObject);
} else if (defaultObject instanceof Integer) {
return sp.getInt(key, (Integer) defaultObject);
} else if (defaultObject instanceof Boolean) {
return sp.getBoolean(key, (Boolean) defaultObject);
} else if (defaultObject instanceof Float) {
return sp.getFloat(key, (Float) defaultObject);
} else if (defaultObject instanceof Long) {
return sp.getLong(key, (Long) defaultObject);
}
return null;
}
/**
* 移除某个key值已经对应的值
*
* @param context
* @param key
*/
public static void remove(Context context, String key) {
SharedPreferences sp = context.getSharedPreferences(FILE_NAME, Context.MODE_PRIVATE);
SharedPreferences.Editor editor = sp.edit();
editor.remove(key);
SharedPreferencesCompat.apply(editor);
}
/**
* 清除所有数据
*
* @param context
*/
public static void clear(Context context) {
SharedPreferences sp = context.getSharedPreferences(FILE_NAME, Context.MODE_PRIVATE);
SharedPreferences.Editor editor = sp.edit();
editor.clear();
SharedPreferencesCompat.apply(editor);
}
/**
* 查询某个key是否已经存在
*
* @param context
* @param key
* @return
*/
public static boolean contains(Context context, String key) {
SharedPreferences sp = context.getSharedPreferences(FILE_NAME, Context.MODE_PRIVATE);
return sp.contains(key);
}
/**
* 返回所有的键值对
*
* @param context
* @return
*/
public static Map<String, ?> getAll(Context context) {
SharedPreferences sp = context.getSharedPreferences(FILE_NAME, Context.MODE_PRIVATE);
return sp.getAll();
}
/**
* 创建一个解决SharedPreferencesCompat.apply方法的一个兼容类
*
* @author dj
*/
private static class SharedPreferencesCompat {
private static final Method sApplyMethod = findApplyMethod();
/**
* 反射查找apply的方法
*
* @return
*/
@SuppressWarnings({"unchecked", "rawtypes"})
private static Method findApplyMethod() {
try {
Class clz = SharedPreferences.Editor.class;
return clz.getMethod("apply");
} catch (NoSuchMethodException e) {
}
return null;
}
/**
* 如果找到则使用apply执行，否则使用commit
*
* @param editor
*/
public static void apply(SharedPreferences.Editor editor) {
try {
if (sApplyMethod != null) {
sApplyMethod.invoke(editor);
return;
}
} catch (IllegalArgumentException e) {
} catch (IllegalAccessException e) {
} catch (InvocationTargetException e) {
e.printStackTrace();
}
editor.commit();
}
}
}
对SharedPreference的使用做了建议的封装，对外公布出put，get，remove，clear等等方法；
注意一点，里面所有的commit操作使用了SharedPreferencesCompat.apply进行了替代，目的是尽可能的使用apply代替commit；
首先说下为什么，因为commit方法是同步的，并且我们很多时候的commit操作都是UI线程中，毕竟是IO操作，尽可能异步；
所以我们使用apply进行替代，apply异步的进行写入；
但是apply相当于commit来说是new API呢，为了更好的兼容，我们做了适配；
4、单位转换工具类
package com.example.dj.testdemo.Utils;
import android.content.Context;
import android.util.TypedValue;
/**
* 描述：单位转换辅助类
* <p>
* Created by dj on 2016/11/17 0017.
*/
public class DensityUtils {
private DensityUtils() {
//不能被实例化
new UnsupportedOperationException("cannot be instantiated");
}
/**
* dp转px
*
* @param context
* @param dpVal
* @return
*/
public static int dp2px(Context context, float dpVal) {
return (int) TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP,
dpVal, context.getResources().getDisplayMetrics());
}
/**
* sp转px
*
* @param context
* @param spVal
* @return
*/
public static int sp2px(Context context, float spVal) {
return (int) TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_SP,
spVal, context.getResources().getDisplayMetrics());
}
/**
* px转dp
*
* @param context
* @param pxVal
* @return
*/
public static float px2dp(Context context, float pxVal) {
final float scale = context.getResources().getDisplayMetrics().density;
return (pxVal / scale);
}
/**
* px转sp
*
* @param context
* @param pxVal
* @return
*/
public static float px2sp(Context context, float pxVal) {
return (pxVal / context.getResources().getDisplayMetrics().scaledDensity);
}
}

import android.os.Environment;
import android.os.StatFs;
import java.io.File;
/**
* 描述：SDCard辅助类
* <p>
* Created by dj on 2016/11/17 0017.
*/
public class SDCardUtils {
private SDCardUtils() {
/* cannot be instantiated */
throw new UnsupportedOperationException("cannot be instantiated");
}
/**
* 判断SDCard是否可用
*
* @return
*/
public static boolean isSDCardEnable() {
return Environment.getExternalStorageState().equals(Environment.MEDIA_MOUNTED);
}
/**
* 获取SD卡路径
*
* @return
*/
public static String getSDCardPath() {
return Environment.getExternalStorageDirectory().getAbsolutePath() + File.separator;
}
/**

*/
public static long getSDCardAllSize() {

return freeBlocks * availableBlocks;
}
return 0;
}
/**
* 获取指定路径所在空间的剩余可用容量字节数，单位byte
*
* @param filePath
* @return 容量字节 SDCard可用空间，内部存储可用空间
*/
public static long getFreeBytes(String filePath) {
// 如果是sd卡的下的路径，则获取sd卡可用容量
if (filePath.startsWith(getSDCardPath())) {
filePath = getSDCardPath();
} else {// 如果是内部存储的路径，则获取内存存储的可用容量
filePath = Environment.getDataDirectory().getAbsolutePath();
}
StatFs stat = new StatFs(filePath);
long availableBlocks = (long) stat.getAvailableBlocks() - 4;
return stat.getBlockSize() * availableBlocks;
}
/**

public static String getRootDirectoryPath() {
return Environment.getRootDirectory().getAbsolutePath();
}
