在android畫面切換時設置跟隨變動的小圓圈

編輯：關於Android編程

前言：我們經常在使用各類安卓APP的時候發現會有如圖所示的小圓圈顯示當前頁所在的，甚至一般來說我們的android桌面上也應該有類似的提示位置的控件。剛開始還以為這是一種控件，於是去查SDK文檔，找了好一會都沒有找到。於是在午休的時候想了想，終於想通了，這東西其實我們完全可以自己去做的，而且原理是相當的簡單的。   好了，廢話不多說，我們就來做一個。   首先這樣的程序涉及到頁面的切換，那麼我們就先建立一個ViewFlipper來存放每一個View視圖。。   其次我說想通了，想通的就是這個小圓圈控件我們完全可以自己去做一個，而且原理很簡單，簡單到一個LinearLayout就能實現。   我們主要布局結構為：   <RelativeLayout>   <ViewFlipper></ViewFlipper>//這裡顯示的就是切換的圖   <LinearLayout></LinearLayout>//這裡顯示的小圓圈之間的切換   <RelativeLayout>     代碼如下，這裡使用的是純代碼布局，不需要用到xml文件。 
public class MyViewFlipper extends RelativeLayout implements OnTouchListener,OnGestureListener{
	
	private ViewFlipper viewflipper;
	private LogView logView;
	private Context parentContext;
	TextView textView;
	TextView[] textViews;
	RFIDDAQ rfiddaq;
	final static int viewflipperid=100;
	GestureDetector detector;//創建手勢監聽的對象
	
	/**
	 * 再次匹配的時間間隔 單位 秒
	 */
	private int time;
	private String address;
	private int maxshownum;//顯示的最大數量，超過這個數量會刷新掉之前的數據。
	
	public MyViewFlipper(Context context) {
		super(context);
		this.parentContext=context;
		 detector=new GestureDetector(this);  
		 init();
	}

	private void init() {
		// TODO Auto-generated method stub
		// 創建滾動顯示框對象
		viewflipper = new ViewFlipper(parentContext);
		viewflipper.setBackgroundColor(Color.CYAN);
		viewflipper.setId(viewflipperid);
		LayoutParams lpviewflipper = new LayoutParams(-1, 500);

		// 創建信息采集框對象，放入viewflipper中作為元素之一
		//這裡的rfiddaq以及下面的都可以logView都可以替換成自定義的View視圖。當然也可以添加新的自定義試圖，只需要添加到viewflipper中就可以了。
		rfiddaq = new RFIDDAQ();
		lpviewflipper.addRule(RelativeLayout.ALIGN_PARENT_TOP);
		viewflipper.addView(rfiddaq);

		// 創建logView顯示界面，放入viewflipper中作為元素之一
		logView = new LogView(parentContext);
		viewflipper.addView(logView);

		// 這裡添加的LinearLayout是包含小圓點的集合
		LinearLayout viewGroup = new LinearLayout(parentContext);
		ViewGroup group = (ViewGroup) viewGroup;
		textViews = new TextView[viewflipper.getChildCount()];
		for (int i = 0; i < viewflipper.getChildCount(); i++) {
			textView = new TextView(parentContext);
			textView.setLayoutParams(new LayoutParams(30, 30));
			textView.setPadding(0, 0, 2, 0);
			textViews[i] = textView;
			if (i == 0) {
				// 默認進入程序後第一張圖片被選中,因為viewflipper默認就是選中第一個視圖
				textViews[i].setBackgroundResource(R.drawable.radio_sel);
			} else {
				textViews[i].setBackgroundResource(R.drawable.radio);
			}
			group.addView(textViews[i]);
		}
		// 設置小圓圈的位置
		LayoutParams lpgroup = new LayoutParams(-2, -2);
		lpgroup.addRule(RelativeLayout.BELOW, viewflipperid);
		lpgroup.addRule(RelativeLayout.CENTER_HORIZONTAL);

		// 把viewflipper和顯示小圓圈框的viewGroup放入RelativeLayout中
		addView(viewflipper, lpviewflipper);
		addView(viewGroup, lpgroup);
		viewflipper.setOnTouchListener(this);//添加動作監聽
		viewflipper.setLongClickable(true);//這一句必須添加，否則手勢監聽無法觸發
	}
