Question

环境：使用Google API的Android 2.3.3

我知道这有点长，但我发布了所有信息，以防您需要参考它。提前谢谢！

我在这里关注了Android示例：http://developer.android.com/guide/tutorials/views/hello-tabwidget.html，但是我收到错误“由以下引起：java.lang.RuntimeException：无法创建标签内容，因为找不到包含id的视图”。

以下是应用流程：应用程序从主屏幕开始，在onStart（）中创建一个Intent并启动CartActivity。在CartActivity开始之前，应用程序崩溃并出现RuntimeException“无法创建选项卡内容，因为找不到ID为2131034112的视图”

CartActivity

import com.cart.R;

import android.app.Activity;
import android.app.TabActivity;
import android.os.Bundle;
import android.util.Log;
import android.widget.EditText;
import android.widget.ListView;
import android.widget.TabHost;
import android.widget.TextView;

public class CartActivity extends TabActivity 
{
    private TextView cartNameLabel;
    private EditText inputCartName;

    private TextView priceLabel;
    private EditText inputPrice;

    private EditText inputFruit;
    private ListView displayFruits;

    private TabHost tabHost;

    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) 
    {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.cart);

        Log.i(this.getClass().toString(), "Before addTabs()");
        addTabs();
        Log.i(this.getClass().toString(), "After addTabs()");

        cartNameLabel = (TextView)findViewById(R.id.createCartNameLabel);

        inputCartName = (EditText)findViewById(R.id.enterCartName);

        priceLabel = (TextView)findViewById(R.id.createPriceLabel);

        inputPrice = (EditText)findViewById(R.id.enterPrice);

        inputFruit = (EditText)findViewById(R.id.enterFruit);    
    }

    /**
     * Adds and displays the tabs to the Activity
     */
    private void addTabs()
    {           
        tabHost = getTabHost();
        tabHost.addTab(tabHost.newTabSpec("Tab1+a").setIndicator("X").setContent(R.id.addTab1a));
        tabHost.addTab(tabHost.newTabSpec("Tab2").setIndicator("Y").setContent(R.id.addTab2));

        tabHost.setCurrentTab(0);
    }   

}

将布局文件的名称更改为 cart.xml

当更改为以下格式时，样本会运行
