充气自定义组件Android时出错

我在尝试给自定义组件充气时遇到错误。

之前使用的是使用LinearLayout开始的组件的xml，但它已经停止工作，因为我将其更改为com.example.football.on.uk.tv.CustomResultComponent。

我做了此更改，以遵循本教程的评论中提出的建议：http://www.anotherandroidblog.com/2011/05/26/custom-composite-android-component/

目前我并不想动态地夸大视图。我在XML的第24行收到错误，第一个是TextView。这个TextView似乎被正确定义，并且在我将此TextView的XML复制到另一个活动时起作用。

以下是我的自定义组件的xml定义： 

<?xml version="1.0" encoding="utf-8"?>
<com.example.football.on.uk.tv.CustomResultComponent
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content">
    <LinearLayout
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:orientation="vertical" >

        <TableLayout
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"

        android:paddingRight="2dip"
        android:paddingTop="1dip" >

        <TableRow
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:gravity="center_horizontal" >

            <TextView
                android:id="@+id/tvHomeTeam"
                android:layout_width="140dip"

                android:text="HomeTeam" />

            <TextView
                android:id="@+id/tvVersus"
                android:layout_width="40dp"
                android:layout_height="fill_parent"
                android:background="@color/White"
                android:gravity="center"
                android:text="  -  " />

            <TextView
                android:id="@+id/tvAwayTeam"
                android:layout_width="140dip"
                android:layout_height="fill_parent"
                android:background="@color/White"
                android:text="Away Team" />
        </TableRow>
    </TableLayout>

    <TableLayout

                android:layout_width="130dip"
                android:layout_height="wrap_content"
                android:background="@color/White"
                android:gravity="center_horizontal"
                android:text=" 01/01/1950    12:45" />

            <TextView
                android:id="@+id/tvCompetition"
                android:layout_width="140dip"
                android:layout_height="wrap_content"
                android:background="@color/White"
                android:gravity="center_horizontal"
                android:text="Premier League" />

            <ImageView
                android:id="@+id/ivChannel"
                android:layout_width="50dp"
                android:layout_height="match_parent"
                android:background="@color/White"
                android:paddingBottom="4dip"
                android:paddingLeft="4dip"
                android:paddingRight="4dip"
                android:paddingTop="4dip"
                android:src="@drawable/logo_espn" />
        </TableRow>
    </TableLayout>
</LinearLayout>

</com.example.football.on.uk.tv.CustomResultComponent>

以下是此组件的类： 

package com.example.football.on.uk.tv;

import android.app.Activity;

import com.example.football.on.uk.tv.R;

import android.content.Context;
import android.text.Layout;
import android.util.AttributeSet;
import android.widget.ImageView;
import android.widget.LinearLayout;
import android.widget.TextView;

public class CustomResultComponent extends LinearLayout{
private TextView tvHomeTeam;
private TextView tvVersus;
private TextView tvAwayTeam;
private TextView tvDateTime;
private TextView tvCompetition;
private ImageView ivChannel;

public CustomResultComponent(Context context, AttributeSet attrs) {
    super(context, attrs);
}

@Override
protected void onFinishInflate(){
    super.onFinishInflate();
        ((Activity)getContext()).getLayoutInflater().inflate(R.layout.custom_result_component, this);
    setupViewItems();
}

private void setupViewItems() {
    // TODO Auto-generated method stub
    tvHomeTeam = (TextView) findViewById(R.id.tvHomeTeam);
    tvVersus = (TextView) findViewById(R.id.tvVersus);
    tvAwayTeam = (TextView) findViewById(R.id.tvAwayTeam);
    tvDateTime = (TextView) findViewById(R.id.tvDateTime);
    tvCompetition = (TextView) findViewById(R.id.tvCompetition);
    ivChannel = (ImageView) findViewById(R.id.ivChannel);
}

public void setHomeTeam(String team){
    tvHomeTeam.setText("Tottenham");
}
}

以下是我希望自定义组件显示的活动的XML： 

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@color/LightBlue"
android:id="@+id/AboutLayout"
android:orientation="vertical">

<com.example.football.on.uk.tv.CustomResultComponent
    android:id="@+id/customResultComponent1"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content">
</com.example.football.on.uk.tv.CustomResultComponent>

</LinearLayout>

以下是活动： 

package com.example.football.on.uk.tv;

import android.os.Bundle;

import android.app.Activity;
import android.view.LayoutInflater;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
import android.widget.LinearLayout;
import android.widget.TextView;
import android.support.v4.app.NavUtils;

import com.example.football.on.uk.tv.CustomResultComponent;

public class About extends Activity {



@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_about);



}



@Override
public boolean onCreateOptionsMenu(Menu menu) {
    getMenuInflater().inflate(R.menu.activity_about, menu);
    return true;
}


@Override
public boolean onOptionsItemSelected(MenuItem item) {
    switch (item.getItemId()) {
        case android.R.id.home:
            NavUtils.navigateUpFromSameTask(this);
            return true;
    }
    return super.onOptionsItemSelected(item);
}

}

最后，这是我收到的错误消息：

为很长的帖子道歉！我想提供尽可能多的信息。
