Question

我正在使用最新的Android设计支持库，我的导航视图分为两组，一组用于我使用from math import sin, cos, sqrt, atan2, radians coord=[] coord1=None def distance(coord1,coord2): #Haversin lat1,lon1=coord1 lat2,lon2=coord2 dlat = radians(lat2-lat1) dlon = radians(lon2-lon1) a = sin(dlat/2) * sin(dlat/2) + cos(radians(lat1))*cos(radians(lat2))*sin(dlon/2)*sin(dlon/2) c = 2 *atan2(sqrt(a),sqrt(1-a)) s = (6367*c)*1000 #meter return s # with open as data will close itself after reading each line. so you don't need to close it yourself with open('asko_nav_2013.nmea', 'r') as indata: #making a indata and outdata, r stands for reading(readcapabilities with open('asko_nav_out.txt', 'w') as outdata: #w stands for write write to a new file(open for writing-you can change things) while True: line = indata.readline() if not line: break if line.startswith('EOL'): #if the line starts with EOL(end of line) it writes it in the output outdata.writelines("EOL") coord1=None elif line.startswith('Line'): LineID=line outdata.writelines('\n%s' %LineID) elif line.startswith('$GPGGA'): #when the fist line starts with $GPGGA it splits the columns data=line.split(",") #the for loop reads the file line by line # Importing only coordinates from asko input file (Row 2 and 4) # Converting the coordinates from DDMM.MMMM to DD.DDDDDD LAT=(data[2]) LAT_D=LAT[0:2] LATID=float(LAT_D) LAT_M=LAT[2:] LATM=float(LAT_M) LATIM = float(LATM) / 60.0 latitude=(LATID + LATIM) LON=(data[4]) LON_D=LON[1:3] LONGD=float(LON_D) LON_M=LON[3:] LONM=float(LON_M) LONGM = float(LONM) / 60.0 longitude=(LONGD + LONGM) if coord1 is None: # The first time through the loop "coord1" is None outdata.writelines('%0.6f\t%0.6f\t%s \n'%(latitude,longitude,0)) coord1=(latitude,longitude) else: coord2=(latitude,longitude) dist=distance(coord1,coord2) if dist <100: continue outdata.writelines('%0.6f\t%0.6f\t%f\n' % (latitude,longitude,dist)) coord1=coord2的片段，一组用于设置和关于我在哪里使用android:checkableBehavior="single"等活动。

这在图书馆的23.0.1版本中运行良好，现在当我使用android:checkableBehavior="none"时，选择时会检查按钮。

这只是库中的错误还是我必须为新版本更改某些内容？我在更改日志中找不到任何内容。

菜单：

compile 'com.android.support:design:+'

布局：

<group
    android:id="@+id/main"
    android:checkableBehavior="single">
    <item
        android:id="@+id/navigation_fragment_1"
        android:icon="@drawable/icon"
        android:title="@string/fragment_1" />
</group>

<group
    android:id="@+id/sub"
    android:checkableBehavior="none">
    <item
        android:id="@+id/navigation_sub_settings"
        android:title="@string/settings" />

</group>

</menu>

Answer 1

我的代码中有一个DATE（这对旧版本没有任何问题），但我猜他们改变了一些东西，所以现在你可以手动检查menuItems，即使它们被设置为menuItem.setChecked(true);。

导航视图：checkableBehavior =“none”无法使用最新版本
