android自定义分页组件

组件代码如下：
[java]
public class PageControl extends LinearLayout implements OnClickListener{
    private ImageButton firstImg;
    private ImageButton preImg;
    private ImageButton nextImg;
    private ImageButton endImg;
    private TextView totalPageText;
    private TextView curPageText;
    private int numPerPage=10;
    private int curPage=1;
    private int count=0;
    private OnPageChangeListener pageChangeListener;
    public PageControl(Context context) {
        super(context);
        initPageComposite(context);
    }
    public PageControl(Context context, AttributeSet attrs) {
        super(context, attrs);
        initPageComposite(context);
    }
    public PageControl(Context context, AttributeSet attrs, int defStyle) {
        super(context, attrs, defStyle);
        initPageComposite(context);
    }
    private void initPageComposite(Context context){
        this.setPadding(5,5,5,5);
        firstImg=new ImageButton(context);
        firstImg.setId(1);
        firstImg.setImageResource(R.drawable.firstpage);
        firstImg.setPadding(0,0,0,0);
        LayoutParams layoutParam=new LayoutParams(LayoutParams.WRAP_CONTENT,LayoutParams.WRAP_CONTENT);
        layoutParam.setMargins(0,0,5,0);
        firstImg.setLayoutParams(layoutParam);
        firstImg.setOnClickListener(this);
        this.addView(firstImg);
        preImg=new ImageButton(context);
        preImg.setId(2);
        preImg.setImageResource(R.drawable.prepage);
        preImg.setPadding(0,0,0,0);
        layoutParam=new LayoutParams(LayoutParams.WRAP_CONTENT,LayoutParams.WRAP_CONTENT);
        layoutParam.setMargins(0,0,5,0);
        preImg.setLayoutParams(layoutParam);
        preImg.setOnClickListener(this);
        this.addView(preImg);
        nextImg=new ImageButton(context);
        nextImg.setId(3);
        nextImg.setImageResource(R.drawable.nextpage);
        nextImg.setPadding(0,0,0,0);
        layoutParam=new LayoutParams(LayoutParams.WRAP_CONTENT,LayoutParams.WRAP_CONTENT);
        layoutParam.setMargins(0,0,5,0);
        nextImg.setLayoutParams(layoutParam);
        nextImg.setOnClickListener(this);
        this.addView(nextImg);
        endImg=new ImageButton(context);
        endImg.setId(4);
        endImg.setImageResource(R.drawable.lastpage);
        endImg.setPadding(0,0,0,0);
        layoutParam=new LayoutParams(LayoutParams.WRAP_CONTENT,LayoutParams.WRAP_CONTENT);
        layoutParam.setMargins(0,0,5,0);
        endImg.setLayoutParams(layoutParam);
        endImg.setOnClickListener(this);
        this.addView(endImg);
        totalPageText=new TextView(context);
        layoutParam=new LayoutParams(LayoutParams.WRAP_CONTENT,LayoutParams.MATCH_PARENT);
        layoutParam.setMargins(5,0,5,0);
        totalPageText.setLayoutParams(layoutParam);
        totalPageText.setText("总页数");
        this.addView(totalPageText);
        curPageText=new TextView(context);
        layoutParam=new LayoutParams(LayoutParams.WRAP_CONTENT,LayoutParams.MATCH_PARENT);
        layoutParam.setMargins(5,0,5,0);
        curPageText.setLayoutParams(layoutParam);
        curPageText.setText("当前页");
        this.addView(curPageText);
    }
    /**
     * 初始化分页组件的显示状态
     * @param newCount
     */
    public void initPageShow(int newCount){
        count=newCount;
        int totalPage=count%numPerPage==0?count/numPerPage:count/numPerPage+1;
        curPage=1;
        firstImg.setEnabled(false);
        preImg.setEnabled(false);
        if(totalPage<=1){
            endImg.setEnabled(false);
            nextImg.setEnabled(false);
        }else{
            endImg.setEnabled(true);
            nextImg.setEnabled(true);
        }
        totalPageText.setText("总页数 "+totalPage);
        curPageText.setText("当前页 "+curPage);
    }
    /**
     * 分页按钮被点击时更新状态,该方法要在initPageShow后调用
     */
