判断手机环境和其他（如是否中文，应用处于前台，网络状态等等）

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[
a525
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;
}
