一、自定义ActionBar
public class ActionBarTool {
public static void setActionBarLayout(Activity act,Context context,int layoutId){//前两个参数一般情况下都可以填this,第三个参数为自定义View的Id
ActionBar actionBar = act.getActionBar();
if( null != actionBar ){
actionBar.setDisplayShowHomeEnabled(false);//是否显示左上角的应用图标
actionBar.setDisplayShowCustomEnabled(true);//是否使用自定义标题栏
LayoutInflater inflator = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View v = inflator.inflate(layoutId, null);//填充自定义布局
ActionBar.LayoutParams layout = new ActionBar.LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT);
actionBar.setCustomView(v,layout);//把自定义View设置成ActionBar
}
}
}
二、系统信息工具类
public class SystemInfoUtils {
public static int getRunningAppProcesses(Context context) {// 得到当前系统内运行的app进程数量
ActivityManager am = (ActivityManager) context
.getSystemService(Context.ACTIVITY_SERVICE);
List<RunningAppProcessInfo> appInfos = am.getRunningAppProcesses();
return appInfos.size();
}
public static List<HashMap<String, Object>> getAppInfo(Context context) {// 得到非系统应用的app信息
List<HashMap<String, Object>> appInfos = new ArrayList<HashMap<String, Object>>();
HashMap<String, Object> map = null;
List<PackageInfo> packages = context.getPackageManager()
.getInstalledPackages(0);// 参数传入0表示过滤权限，因为可能有的手机不让你获取应用信息
for (PackageInfo temp : packages) {
if ((temp.applicationInfo.flags & temp.applicationInfo.FLAG_SYSTEM) == 0) {
// 非系统应用
// 得到应用的名称
String appName = temp.applicationInfo.loadLabel(
context.getPackageManager()).toString();
// 得到应用图标
Drawable appIcon = temp.applicationInfo.loadIcon(context
.getPackageManager());
// 得到应用最后一次更新的时间
long lastUpdateTime = temp.lastUpdateTime;
// 得到应用的包名
String packageName = temp.packageName;
// 得到应用的版本信息
String versionName = temp.versionName;
map = new HashMap<String, Object>();
map.put("appName", appName);
map.put("appIcon", appIcon);
map.put("lastUpdateTime", lastUpdateTime);
map.put("packageName", packageName);
map.put("versionName", versionName);
appInfos.add(map);// 把应用信息加入集合中返回
map = null;
} else {
// 系统应用
}
}
return appInfos;
}
// 获取sd卡容量
public static String getSdSize(Context context) {
String totalStr = null, availStr = null;
if (Environment.getExternalStorageState().equals(
Environment.MEDIA_MOUNTED)) {// 判断是否检测到sd卡
File path = Environment.getExternalStorageDirectory();
StatFs stat = new StatFs(path.getPath());
long blockSize = stat.getBlockSizeLong();
long availableBlocks = stat.getAvailableBlocksLong();
long totalBlocks = stat.getBlockCountLong();
long totalSize = blockSize * totalBlocks;
long availSize = blockSize * availableBlocks;
totalStr = Formatter.formatFileSize(context, totalSize);
availStr = Formatter.formatFileSize(context, availSize);
} else
Toast.makeText(context, "没有检测到SD卡，请检查是否正确插入", Toast.LENGTH_SHORT)
.show();
return "SD卡总容量为:" + totalStr + "可用为:" + availStr;
}
// 获取手机内存
public static String getRomSave(Context context) {
String totalStr = null, availStr = null;
File path = Environment.getDataDirectory();
StatFs stat = new StatFs(path.getPath());// 得到手机内存的路径
long blockSize = stat.getBlockSizeLong();
long availableBlocks = stat.getAvailableBlocksLong();
long totalBlocks = stat.getBlockCountLong();
long totalSize = blockSize * totalBlocks;
long availSize = blockSize * availableBlocks;
totalStr = Formatter.formatFileSize(context, totalSize);
availStr = Formatter.formatFileSize(context, availSize);
return "手机内存总大小为:" + totalStr + "可用空间为:" + availStr;
}
}三、网络相关工具类public class NetworkUtils {
// 判断当前网络是否可用
public static boolean networkIsConnect(Context context) {
ConnectivityManager conn = (ConnectivityManager) context
.getSystemService(Context.CONNECTIVITY_SERVICE);
NetworkInfo info = conn.getActiveNetworkInfo();
if (info != null && info.isConnected()) {
return true;
} else {
return false;
}
}
// 判断当前连接的网络是否是wifi，并得到连接当前Wifi的信息
public static boolean networkIsWifi(Context context) {
ConnectivityManager conn = (ConnectivityManager) context
.getSystemService(Context.CONNECTIVITY_SERVICE);
NetworkInfo info = conn.getActiveNetworkInfo();
if (info != null && info.isConnected()
&& info.getType() == ConnectivityManager.TYPE_WIFI) {
WifiManager wifiManager = (WifiManager) context
.getSystemService(Context.WIFI_SERVICE);
WifiInfo wifiInfo = wifiManager.getConnectionInfo();
Toast.makeText(context, "连接的wifi网络的id为："+wifiInfo.getNetworkId(), Toast.LENGTH_SHORT).show();
return true;
} else {
return false;
}
}
// 是否打开Wifi
public static void setWifiEnabled(Context context, boolean enabled) {
WifiManager wifiManager = (WifiManager) context
.getSystemService(Context.WIFI_SERVICE);
if (enabled) {
wifiManager.setWifiEnabled(true);
} else {
wifiManager.setWifiEnabled(false);
}
}
}四、Px与Dp转化工具类
public class DensityUtils {
public static int Dp2Px(Context context, float dp) {
final float scale = context.getResources().getDisplayMetrics().density;
return (int) (dp * scale + 0.5f);
}
public static int Px2Dp(Context context, float px) {
final float scale = context.getResources().getDisplayMetrics().density;
return (int) (px / scale + 0.5f);
}
}五、震动工具类
public class VibratorUtil {
/**
* long milliseconds ：震动的时长，单位是毫秒
* long[] pattern ：自定义震动模式 。数组中数字的含义依次是[静止时长，震动时长，静止时长，震动时长。。。]时长的单位是毫秒
* boolean isRepeat ： 是否反复震动，如果是true，反复震动，如果是false，只震动一次
*/
public static void Vibrate(final Context context) {
long milliseconds = 100;
Vibrator vib = (Vibrator) context.getSystemService(Service.VIBRATOR_SERVICE);
vib.vibrate(milliseconds);
}
public static void Vibrate(final Context context, long milliseconds) {
Vibrator vib = (Vibrator) context.getSystemService(Service.VIBRATOR_SERVICE);
vib.vibrate(milliseconds);
}
public static void Vibrate(final Context context, long[] pattern,boolean isRepeat) {
Vibrator vib = (Vibrator) context.getSystemService(Service.VIBRATOR_SERVICE);
vib.vibrate(pattern, isRepeat ? 1 : -1);//-1为反复震动
}
