判断app是否在界面显示（焦点）

public static boolean isAppInForeground(Context context) {        ActivityManager activityManager = (ActivityManager) context                .getSystemService(Context.ACTIVITY_SERVICE);        List<RunningAppProcessInfo> appProcesses = activityManager                .getRunningAppProcesses();        for (RunningAppProcessInfo appProcess : appProcesses) {            if (appProcess.processName.equals(context.getPackageName())) {                return appProcess.importance == RunningAppProcessInfo.IMPORTANCE_FOREGROUND;            }        }        return false;    }

判断当前语言环境是否为中文

public static boolean isZh(Context context) {        Locale locale = context.getResources().getConfiguration().locale;        String language = locale.getLanguage();        if (language.endsWith("zh"))            return true;        else            return false;    }

判断当前网络是否可用

public static boolean isNetwork(Activity activity) {        Context context = activity.getApplicationContext();        // 获取手机所有连接管理对象（包括对wi-fi,net等连接的管理）        ConnectivityManager connectivityManager = (ConnectivityManager) context                .getSystemService(Context.CONNECTIVITY_SERVICE);        if (connectivityManager == null) {            return false;        } else {            // 获取NetworkInfo对象            NetworkInfo[] networkInfo = connectivityManager.getAllNetworkInfo();            if (networkInfo != null && networkInfo.length > 0) {                for (int i = 0; i < networkInfo.length; i++) {                    System.out.println(i + "===状态==="                            + networkInfo[i].getState());                    System.out.println(i + "===类型==="                            + networkInfo[i].getTypeName());                    // 判断当前网络状态是否为连接状态                    if (networkInfo[i].getState() == NetworkInfo.State.CONNECTED) {                        return true;                    }                }            }        }        return false;    }

判断网络状态是移动网络还是wifi网络

public static String getNetworkType(Context mContext) {        String netType = "";        ConnectivityManager connectivityManager = (ConnectivityManager) mContext.getSystemService(Context.CONNECTIVITY_SERVICE);        NetworkInfo networkInfo = connectivityManager.getActiveNetworkInfo();        if (networkInfo == null) {            return netType;        }        int nType = networkInfo.getType();        if (nType == ConnectivityManager.TYPE_MOBILE) {            //移动网络            netType = "NETTYPE_CMNET";        } else if (nType == ConnectivityManager.TYPE_WIFI) {            //WIFI网络            netType = "NETTYPE_WIFI";        }        return netType;    }

判断手机中是否安装指定包名的软件

public static boolean isInstallByread(Context context, String name) {        List<PackageInfo> packages = context.getPackageManager()                .getInstalledPackages(0);        for (int i = 0; i < packages.size(); i++) {            PackageInfo packageInfo = packages.get(i);            if (packageInfo.packageName.equals(name)) {                return true;            } else {                continue;            }        }        return false;    }

判断当前情景模式（如静音模式，震动模式）

public static String isSceneMode(Context mContext){        AudioManager audio = (AudioManager) mContext                .getSystemService(Context.AUDIO_SERVICE);        String type = "正常模式";        if (audio.getRingerMode()==AudioManager.RINGER_MODE_SILENT) {            type = "静音模式";        }else if(audio.getRingerMode()==                AudioManager.RINGER_MODE_VIBRATE){            type = "震动模式";        }        return type;    }
