问题描述

我要zxing QR code扫描器，其中是有我的应用程序三个选项卡我的应用程序集成。

I want to integrate zxing qr code scanner in my application which is having three tabs in my application.

目前，当我的标签栏按钮操的人得到当时pssed我打电话zxing QR code的scann活动$ P $但是当过它的调用它显示象下面这样的错误。

Currently when my one of the tab bar butto gets pressed at that time I am calling zxing qr code's scann activity but when ever its calling it is showing error like below.

java.lang.RuntimeException: Unable to start activity ComponentInfo{com.example.beepz/com.google.zxing.client.android.CaptureActivity}: java.lang.RuntimeException: Your content must have a TabHost whose id attribute is 'android.R.id.tabhost'

而我的code是有两个选项卡主机控制和我在电话的活动实例标签主机，如下图所示。

Rather my code is having both tab host control and I have instantiated tab host in my activity call as shown below.

            android:background="@color/transparent" />

    </SurfaceView>
</FrameLayout>

Java文件：（CaptureActivity.java）

Java File : (CaptureActivity.java)

public final class CaptureActivity extends TabActivity implements
    SurfaceHolder.Callback {

private TabHost tabHost;

public void onCreate(Bundle savedInstanceState) {

    super.onCreate(savedInstanceState);

    Window window = getWindow();
    window.addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);
    window.setFormat(PixelFormat.TRANSLUCENT);

    setContentView(R.layout.capture);

    tabHost = getTabHost();
    Intent intent = new Intent().setClass(this, first.class);      
    TabSpec spec = tabHost.newTabSpec("First Tab").setIndicator("First Tab",getResources().getDrawable(R.drawable.iconinfo)).setContent(intent); 
    tabHost.addTab(spec);
    .
    .
    .

}

我是否需要更改清单文件或其他任何东西，我需要做的事情吗？

Do I need to change any thing in manifest file or anything else I need to do?

任何机构可以帮我我该怎么办？

Can any body please help me what should I do?

在此先感谢...

推荐答案

最后我解决我自己我的问题，问题是，有在我的主要项目CaptureActivity.java文件。并通过在主项目的CaptureActivity.java文件中添加TabHost解决的问题。

At last I solved my problem on my own, the problem was, there was a CaptureActivity.java file in my main project. And problem solved by adding TabHost in the main project's CaptureActivity.java file.

希望这将有助于其他人了。
