小编ata*_*oyh的帖子

text = text + CepVizyon.getPhoneCode() + "\n\n"
            + getText(R.string.currentversion) + CepVizyon.getLicenseText();
    activationText.setText(text);   
myTextView.setText(text);

我想改变CepVizyon.getPhoneCode()字符串的颜色.我怎样才能做到这一点？

首先,我在Main Activity中编写了一些方法,但我认为它们应该是一个类.

这是我的代码... openFileOutput和openFileInput是未定义的.任何的想法？？也许它应该是服务或活动......？

    package spexco.hus.system;

    import java.io.FileInputStream;
    import java.io.FileNotFoundException;
    import java.io.FileOutputStream;
    import java.io.IOException;
    import java.util.Date;
    import spexco.hus.cepvizyon.CepVizyon;
    import android.content.Context;

    public class LicenseIDB {
    private String PHONECODEFILE = "CepVizyonCode";
    private static String PhoneCode = null;

    public LicenseIDB() {
    if (readLocal(PHONECODEFILE, 8) == null)
        createSystemCode();
}

public static long getDate() {
    Date currentTime = new Date();
    return currentTime.getTime();
}

public void createSystemCode() {
    long date = getDate();
    String str = Integer.toHexString(Integer.MAX_VALUE - (int) date);
    for (int i = str.length(); i < …

我想问一下,使用两个或多个嵌套的RelativeLayout.第一个代码看起来像图片1,当我添加android:layout_alignParentRight="true"第二个RelativeLayout时,这看起来像图片2.我想将文本对齐到第二个RelativeLayout.我的错在哪里？

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout

        android:layout_width="wrap_content"

        android:layout_height="wrap_content"
        android:id="@+id/testRL">

                android:layout_alignParentRight="true"
                android:layout_alignParentTop="true"

                        android:id="@+id/amountLayoutTV" />
        </RelativeLayout>
</RelativeLayout>

图片1:

我补充说 android:layout_alignParentRight="true"

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="wrap_content"

    android:id="@+id/testRL">
    <RelativeLayout

            android:layout_height="wrap_content"
            android:layout_alignParentRight="true"
            android:layout_alignParentTop="true"
            android:id="@+id/testRotateLL"
            android:background="@drawable/picture_border_offer_first_page">
            <TextView
                    android:layout_height="wrap_content"
                    android:layout_width="wrap_content"
                    android:text="7000TL"
                    android:layout_alignParentRight="true"
                    android:textSize="15sp"
                    android:textColor="@android:color/white"
                    android:id="@+id/amountLayoutTV" />
    </RelativeLayout>
</RelativeLayout>

我正在使用OPENCV开发一个项目.我在onCameraFrame上有一些过程.虽然它显示预览,但用户可以拍照.但在某些设备中,我在调用takePicture(...)方法后出错.我该怎么办？

E/Camera-JNI(11783): Manually set buffer was too small! Expected 539380 bytes, but got 460800!

新症状:此缓冲区的大小是我的帧大小460800.我在onCameraFrame上记录了帧大小.每帧的大小都是460800.据我了解,takePicture尝试使用预览缓冲区.他们的尺寸不同.

我需要旋转一个布局(有一个TextView和ImageView),它应该在RelativeLayout中右对齐和顶部对齐.我创建了我的布局,这个布局放在右上角.但如果我旋转它我不能正确对齐.我该怎么办？

我的相对布局

    <RelativeLayout
        xmlns:android="http://schemas.android.com/apk/res/android"
        android:layout_width="wrap_content"
        android:background="@drawable/background"
        android:layout_height="wrap_content"
        android:id="@+id/testRL">

        <RelativeLayout
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:layout_alignParentRight="true"
                android:layout_alignParentTop="true"
                android:id="@+id/testRotateLL">

                <ImageView
                        android:layout_height="wrap_content"
                        android:layout_width="wrap_content"
                        android:background="@drawable/picture_border_offer_first_page" />
                <TextView
                        android:layout_height="wrap_content"
                        android:layout_width="wrap_content"
                        android:text="7000TL"
                        android:textSize="15sp"
                        android:layout_centerInParent="true"
                        android:textColor="@android:color/white"
                        android:id="@+id/amountLayoutTV" />
        </RelativeLayout>
</RelativeLayout>

然后我用动画旋转这个linearLayout.旋转好,..

<rotate
        xmlns:android="http://schemas.android.com/apk/res/android"
        android:fromDegrees="0"
        android:toDegrees="45"
        android:pivotX="50%"
        android:pivotY="50%"
        android:fillEnabled="true"
        android:detachWallpaper="true"
        android:duration="0"
        android:fillAfter="true">
</rotate>

旋转新视觉后...

我在我的应用程序上连接到两台服务器(PROD是https,测试服务器是http).

在J2ME上:我可以毫无问题地连接到这两台服务器.在Android上我无法连接到测试服务器.当连接是http时,如果我不使用setChunkedStreamingMode,我不能得到,responseCode(StringIndexOutOfBoundsException);如果我使用setChunkedStreamingMode,响应代码是401.我该怎么办,我的错在哪里？

这是我的android代码,如果你想看J2me代码,我也可以添加它.

URL url = new URL(getUrl());
            URLConnection conn = url.openConnection();
            HttpURLConnection httpConn = (HttpURLConnection) conn;
            httpConn.setAllowUserInteraction(false);
            httpConn.setInstanceFollowRedirects(true);
            httpConn.setConnectTimeout(10000);
            httpConn.setRequestProperty("User-Agent", util.getDeviceFullModel()
                    + " " + util.getSoftwareVersion());
            httpConn.setRequestProperty("Accept-Charset", "utf-8");

            httpConn.setRequestProperty("Content-Type",
                    "text/xml; charset=utf-8");
            httpConn.setRequestProperty("SOAPAction",
                    "http://tempuri.org/IAuthenticationServiceForGroup/"+conTypeString);
            httpConn.setRequestProperty("Software-Version", AppData.VERSION);
            httpConn.setChunkedStreamingMode(getParams().getBytes("UTF8").length);
            httpConn.setRequestMethod("POST");
            httpConn.setDoOutput(true);
            httpConn.setDoInput(true);
            httpConn.connect();

            os = httpConn.getOutputStream();
            os.write(getParams().getBytes("UTF8"));

            try {
                os.close();
            } catch (Exception e) {
                onError(e);
            }
            response=httpConn.getResponseCode();

J2ME代码:

HttpConnection c = (HttpConnection)XConnection.openConnection(XConnection.SERVER + "AuthenticationServiceForGroup.svc");

            c.setRequestProperty("User-Agent", XUtil.getDeviceFullModel() + " " + XUtil.getSoftwareVersion());
            c.setRequestProperty("Content-Type", "text/xml; …

我有一个处理配置更改的活动.但现在我必须改变布局.我尝试在onConfigurationChanged回调中再次设置布局并希望得到正确的布局(土地),但它仍然显示纵向视图的第一个布局(有两个布局(同名)放置在res/layout和res/layout-land :)

如果我删除android:configChanges ="orientation",它应该是,但是需要处理onConfigurationChanged.我该怎么办？？

我可以在Android 上的dalvik VM上运行C代码吗？

VM运行字节代码,但我需要在dalvik-VM上为myApps运行c代码.可能吗？？

我一直在尝试创建一个架构。它代表我的对象，就像{name:"Joe Doe", id:"1234567890"}But 在创建新对象的第一个请求上；它不应该在对象中包含 id 参数。否则它可能意味着对消费者的更新......

您对实现它的最佳方法有什么想法吗？

我需要什么作为 joi 架构；

joi.object().keys({
    id: joi.string().forbidden() or required(),
    name: joi.string(),
    ...

样品请求；

创建：

POST请求...'api/v1/item/'

目的 ： {name:"Joe Doe"}

更新：

PUT请求...'api/v1/item/'

目的 ： {id:"1234567890", name:"Joe Doe"}

我有CameraList类提供Cameras列表,如"SONY","VIVOTEK","VIVOTEK 7XXX","PIXORD","TOSHIBA","JVC E-CON"......

我想在我的微调器中列出它们,但我不能.有我的代码..

public class AddCam extends MainActivity {
    CameraList cams = new CameraList();

    @Override
    public void onCreate(Bundle savedInstanceState) {
        // TODO Auto-generated method stub
        super.onCreate(savedInstanceState);

        Toast msg = Toast.makeText(AddCam.this, getString(R.string.add_new), Toast.LENGTH_LONG);

        msg.setGravity(Gravity.CENTER, msg.getXOffset() / 2, msg.getYOffset() / 2);

        String a = getString(R.string.add_new);

        TextView tv = (TextView) findViewById(R.id.head);
        tv.setText(getString(R.string.add_new));

        Spinner s = (Spinner) findViewById(R.id.spinner);

        ArrayAdapter<?> adapter = ArrayAdapter.createFromResource(
        this, R.array.cameras, android.R.layout.simple_spinner_item);
        adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
        //s.setAdapter(adapter); **** there is null po?nter ex.
        setContentView(R.layout.spinnerex);
    }
}

我的camlist代码是

public class CameraList {
    private static …

我需要将Activity更改为ListActivity.但是我无法启动我的项目...是否需要更改manifest.xml？

或者我如何将屏幕从Activity更改为ListActivity？有什么不同startActivity(new Intent(this, list.class))吗？

我需要开发一个有两个标签的按钮.

我找到一些关于自定义视图的好文章,但我无法想象如何创建一个myButton类(其中包含自定义布局)扩展按钮...是否可能..

另外在XML中有些视图,布局......我们怎么能这样做？
