Question

嘿我刚写了一个横向进度条。进度条获取此后台资源：

<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item android:id="@android:id/background">
    <inset xmlns:android="http://schemas.android.com/apk/res/android"
        android:drawable="@drawable/progress_bg" />
</item>
<item android:id="@android:id/progress" android:gravity="center">
    <clip>
        <shape>
            <corners android:radius="5dip" />
            <solid android:color="#FFF" />
        </shape>
    </clip>
</item>

这样可以正常工作，但白色进度与背景高度相同。但是我希望进度小于进度条的背景，因为thre背景有一个不应该重叠的边界。

有什么想法吗？感谢

Answer 1

还有：

<item android:id="@android:id/secondaryProgress"></item>

你也改变了吗？

您可以尝试将android:top，android:left，android:right和android:bottom添加到白色进度条item，以便向条形图添加填充。

<item android:id="@android:id/progress" android:gravity="center"
    android:top="2dp" android:left="2dp" android:right="2dp" android:bottom="2dp">
    <clip>
        <shape>
            <corners android:radius="5dip" />
            <solid android:color="#FFF" />
        </shape>
    </clip>
</item>

Answer 3

实际上，我没有使用它。

完整的xml是：

<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item android:id="@android:id/background">
    <inset xmlns:android="http://schemas.android.com/apk/res/android"
        android:drawable="@drawable/progress_bg" />
</item>
<item android:id="@android:id/secondaryProgress" android:gravity="center">
    <clip>
        <shape>
            <corners android:radius="5dip" />
            <solid android:color="#FFF" />
        </shape>
    </clip>
</item>

嗨尝试添加没有颜色的笔触（不透明度最大）我用渐变进度条尝试了这段代码：

class PLCH_DLL_DECL CEasyPLCHandler : public CPLCHandler
{
public:
    CEasyPLCHandler(RTS_HANDLE hLogFile = RTS_INVALID_HANDLE);
    CEasyPLCHandler(PlcConfig *pPlcConfig, PlcDeviceDesc *pDeviceDesc, RTS_HANDLE hLogFile = RTS_INVALID_HANDLE);
    CEasyPLCHandler(unsigned long ulId, char *pszIniFile, RTS_HANDLE hLogFile = RTS_INVALID_HANDLE);
    CEasyPLCHandler(char *pszPlcName, char *pszIniFile, RTS_HANDLE hLogFile = RTS_INVALID_HANDLE);
    virtual ~CEasyPLCHandler(void);

    // See PLCConfig.h for defines of pszProtocol
    // e.g. #define PLCC_DN_TCPIP_L2ROUTE   "Tcp/Ip (Level 2 Route)"
    virtual long ConnectTcpipViaGateway(char *pszGatewayIP, char *pszPlcIP, char *pszProtocol = PLCC_DN_TCPIP_L2ROUTE, int bMotorola = 0, int bLoadSymbols = 1, unsigned long ulTimeout = PLCHANDLER_USE_DEFAULT, unsigned long ulPort = 1200); 
    virtual long ConnectRs232ViaGateway(char *pszGatewayIP, short sPort, unsigned long ulBaudrate, int bMotorola = 0, int bLoadSymbols = 1, unsigned long ulTimeout = PLCHANDLER_USE_DEFAULT);
    virtual long ConnectRs232ViaGatewayEx(char *pszGatewayIP, short sPort, unsigned long ulBaudrate, int bMotorola = 0, int bLoadSymbols = 1, unsigned long ulTimeout = PLCHANDLER_USE_DEFAULT, EXT_RS232_PARAMStyp *pExtParams = NULL);
    virtual long ConnectTcpipViaArti(char *pszPlcIP, char *pszProtocol = PLCC_DN_TCPIP_L2ROUTE, int bMotorola = 0, int bLoadSymbols = 1, unsigned long ulTimeout = PLCHANDLER_USE_DEFAULT, unsigned long ulPort = 1200);
    virtual long ConnectRs232ViaArti(short sPort, unsigned long ulBaudrate, int bMotorola = 0, int bLoadSymbols = 1, unsigned long ulTimeout = PLCHANDLER_USE_DEFAULT);
    virtual long ConnectToSimulation(char *pszSdbFile, int bLoadSymbols = 1, unsigned long ulTimeout = PLCHANDLER_USE_DEFAULT);
    virtual long ConnectViaGateway3(char *pszGatewayIP, char *pszAddress, int bLoadSymbols = 1, unsigned long ulTimeout = PLCHANDLER_USE_DEFAULT);
    virtual long ConnectViaGateway3Ex(char *pszGatewayIP, unsigned long ulPort, char *pszAddress, int bLoadSymbols = 1, unsigned long ulTimeout = PLCHANDLER_USE_DEFAULT);
    virtual long ConnectViaArti3(char *pszAddress, int bLoadSymbols = 1, unsigned long ulTimeout = PLCHANDLER_USE_DEFAULT);
    virtual long ConnectToSimulation3(char *pszSdb3XmlFile, int bLoadSymbols = 1, unsigned long ulTimeout = PLCHANDLER_USE_DEFAULT);


    // Attention: The structure of the service must be known in detail! 
    //            An erroneous service might cause a crash of the PLC! 
    // Send own service to plc and receive reply
    virtual long SyncSendService(/*[In]*/ unsigned char *pbySend, /*[In]*/ unsigned long ulSendSize, /*[Out]*/ unsigned char **ppbyRecv, /*[Out]*/ unsigned long *pulRecvSize);
    // Send own service to plc
    virtual long AsyncSendService(/*[Out]*/ int *piInvokeId, /*[In]*/ unsigned char *pbySend, /*[In]*/ unsigned long ulSendSize, /*[In]*/ CPLCHandlerCallback *pAsyncServiceCallback = NULL);
    // Get service reply
    virtual long AsyncGetServiceReply(/*[In]*/ int *piInvokeId, /*[Out]*/ unsigned char **ppbyRecv, /*[Out]*/ unsigned long *pulRecvSize, long *plServiceResult);
    // Get SessionId for Device services (only used for GW3 and ARTI3) 
    virtual unsigned long GetDeviceSessionId(void);
};

所以你的代码应该是这样的：

pPLCHandler = new CEasyPLCHandler(RTS_INVALID_HANDLE);

为我工作，希望它适合你：D
