自定义View出现的包没有引入问题解决方案

        使用adt14,android 虚拟机2.2 的配置 自定义View

package com.view.my;

import com.view.R;

import android.content.Context;
import android.content.res.TypedArray;
import android.graphics.Canvas;
import android.graphics.Color;
import android.graphics.Paint;
import android.graphics.Paint.Style;
import android.util.AttributeSet;
import android.view.View;

public class MyTextView extends View {
	private Paint paint;

	public MyTextView(Context context, AttributeSet attrs) {
		super(context, attrs);
		paint = new Paint();
		TypedArray typeArray=context.obtainStyledAttributes(attrs,R.styleable.MyView);
		 int textColor = typeArray.getColor(R.styleable.MyView_textColor, 0XFF00FF00); //提供默认值,放置未指定  
	        float textSize = typeArray.getDimension(R.styleable.MyView_textSize, 36);  
	        paint.setColor(textColor);  
	        paint.setTextSize(textSize);  
	        
	}

	@Override
	protected void onDraw(Canvas canvas) {
		// TODO Auto-generated method stub
		super.onDraw(canvas);
		paint.setStyle(Style.FILL); //设置填充  
        canvas.drawRect(10, 10, 100, 100, paint); //绘制矩形  
          
        paint.setColor(Color.BLUE);  
        canvas.drawText("我是被画出来的", 10, 120, paint);  
	}
	
}

 value下的testView.xml 的xml文件:

<?xml version="1.0" encoding="utf-8"?>
<resources>
	<declare-styleable name="MyView">
	    <attr name="textColor" format="color"/>  
        <attr name="textSize" format="dimension"/>  
	</declare-styleable>
    
</resources>

 layout文件main.xml文件最主要

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout 
    xmlns:my="http://schemas.android.com/apk/res-auto"
    xmlns:android="http://schemas.android.com/apk/res/android"
    
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical" >

    <TextView 
        android:layout_width="fill_parent" 
        android:layout_height="wrap_content" 
        android:text="@string/hello" /> 
    <com.view.my.MyTextView
        android:layout_width="fill_parent"
        android:layout_height="wrap_content" 
        android:text="@string/hello"
        my:textColor="#FFFFFFFF"   
        my:textSize="22dp"
         />

</LinearLayout>

 在运行中出现:xmlns:my="http://schemas.android.com/apk/res"没有引入原因是adt升级的时候把包也更新了改成了xmlns:my="http://schemas.android.com/apk/res-auto"

自定义类中的所有类都要初始化,不然你会看到像:Bind #14 的错误
