我們先看下效果圖：
在看程式碼之前先看下整體結構的佈局檔案activity_main.xml
上面是一個帶刪除按鈕的EditText，我們在輸入框中輸入可以自動過濾出我們想要的東西，當輸入框中沒有資料自動替換到原來的資料列表，然後下面一個ListView用來顯示資料列表，右側是一個字母索引表，當我們點選不同的字母,ListView會定位到該字母地方，瞭解了佈局之後，我們先看下專案結構吧<?xml version="1.0" encoding="utf-8"?> <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:orientation="vertical" tools:context="pcp.zyqj.zz.phonecontactpeople.MainActivity"> <!--標題欄--> <include layout="@layout/titlebar_blue" /> <!--檢索欄--> <pcp.zyqj.zz.phonecontactpeople.phonecontactpeople.ClearEditText android:id="@+id/filter_edit" android:layout_width="fill_parent" android:layout_height="35dp" android:layout_marginBottom="5dip" android:layout_marginTop="5dip" android:background="@drawable/search_bar_edit_selector" android:drawableLeft="@drawable/search_bar_icon_normal" android:drawablePadding="10dp" android:hint="請輸入關鍵字" android:paddingLeft="10dp" android:paddingRight="15dp" android:singleLine="true" android:textSize="14sp" /> <FrameLayout android:layout_width="fill_parent" android:layout_height="fill_parent"> <!--聯絡人列表--> <ListView android:id="@+id/country_lvcountry" android:layout_width="fill_parent" android:layout_height="fill_parent" android:layout_gravity="center" android:divider="@null" /> <RelativeLayout android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_gravity="center"> <TextView android:id="@+id/dialog" android:layout_width="50.0dip" android:layout_height="50.0dip" android:layout_alignParentRight="true" android:layout_marginRight="70dp" android:background="@drawable/show_head_toast_bg" android:gravity="center" android:textColor="#ffffffff" android:textSize="25.0dip" android:visibility="invisible" /> </RelativeLayout> <!--右側滑動檢索條--> <pcp.zyqj.zz.phonecontactpeople.phonecontactpeople.SideBar android:id="@+id/sidrbar" android:layout_width="30.0dip" android:layout_height="fill_parent" android:layout_gravity="right|center" /> </FrameLayout> </LinearLayout>
通過佈局檔案可以看出每一個部分的職責，然後看下方法類：
先看下ClearEditText：檢索欄
ClearEditText類是自定義的一個在右側有刪除圖片的EditText，當然你也可以用Android原生的EditText，該類我之前有介紹，我這裡就不貼上程式碼了Android 帶清除功能的輸入框控制元件ClearEditText,仿IOS的輸入框
/** * Created by 李金偉 on 2016/12/23. * 自定義的一個在右側有刪除圖片的EditText，當然你也可以用Android原生的EditText */ public class ClearEditText extends EditText implements OnFocusChangeListener, TextWatcher { /** * 刪除按鈕的引用 */ private Drawable mClearDrawable; public ClearEditText(Context context) { this(context, null); } public ClearEditText(Context context, AttributeSet attrs) { //這裡構造方法也很重要，不加這個很多屬性不能再XML裡面定義 this(context, attrs, android.R.attr.editTextStyle); } public ClearEditText(Context context, AttributeSet attrs, int defStyle) { super(context, attrs, defStyle); init(); } private void init() { //獲取EditText的DrawableRight,假如沒有設定我們就使用預設的圖片 mClearDrawable = getCompoundDrawables()[2]; if (mClearDrawable == null) { mClearDrawable = getResources().getDrawable(R.drawable.emotionstore_progresscancelbtn); } mClearDrawable.setBounds(0, 0, mClearDrawable.getIntrinsicWidth(), mClearDrawable.getIntrinsicHeight()); setClearIconVisible(false); setOnFocusChangeListener(this); addTextChangedListener(this); } /** * 因為我們不能直接給EditText設定點選事件，所以我們用記住我們按下的位置來模擬點選事件 * 當我們按下的位置 在 EditText的寬度 - 圖示到控制元件右邊的間距 - 圖示的寬度 和 * EditText的寬度 - 圖示到控制元件右邊的間距之間我們就算點選了圖示，豎直方向沒有考慮 */ @Override public boolean onTouchEvent(MotionEvent event) { if (getCompoundDrawables()[2] != null) { if (event.getAction() == MotionEvent.ACTION_UP) { boolean touchable = event.getX() > (getWidth() - getPaddingRight() - mClearDrawable.getIntrinsicWidth()) && (event.getX() < ((getWidth() - getPaddingRight()))); if (touchable) { this.setText(""); } } } return super.onTouchEvent(event); } /** * 當ClearEditText焦點發生變化的時候，判斷裡面字串長度設定清除圖示的顯示與隱藏 */ @Override public void onFocusChange(View v, boolean hasFocus) { if (hasFocus) { setClearIconVisible(getText().length() > 0); } else { setClearIconVisible(false); } } /** * 設定清除圖示的顯示與隱藏，呼叫setCompoundDrawables為EditText繪製上去 * @param visible */ protected void setClearIconVisible(boolean visible) { Drawable right = visible ? mClearDrawable : null; setCompoundDrawables(getCompoundDrawables()[0], getCompoundDrawables()[1], right, getCompoundDrawables()[3]); } /** * 當輸入框裡面內容發生變化的時候回撥的方法 */ @Override public void onTextChanged(CharSequence s, int start, int count, int after) { setClearIconVisible(s.length() > 0); } @Override public void beforeTextChanged(CharSequence s, int start, int count, int after) { } @Override public void afterTextChanged(Editable s) { } /** * 設定晃動動畫 */ public void setShakeAnimation(){ this.setAnimation(shakeAnimation(5)); } /** * 晃動動畫 * @param counts 1秒鐘晃動多少下 * @return */ public static Animation shakeAnimation(int counts){ Animation translateAnimation = new TranslateAnimation(0, 10, 0, 0); translateAnimation.setInterpolator(new CycleInterpolator(counts)); translateAnimation.setDuration(1000); return translateAnimation; } }
再看下SideBar:右側上下滑動檢索。
SideBar類就是ListView右側的字母索引View，我們需要使用setTextView(TextView mTextDialog)來設定用來顯示當前按下的字母的TextView,以及使用setOnTouchingLetterChangedListener方法來設定回撥介面，在回撥方法onTouchingLetterChanged(String s)中來處理不同的操作
/**

// 觸控事件

}Java漢字轉換為拼音:CharacterParser

} 資料的介面卡類，該類需要實現SectionIndexer介面，該介面是用來控制ListView分組的，該介面有三個方法getSectionForPosition(int position)，getPositionForSection(int section)，getSections()，我們只需要自行實現前面兩個方法
getSectionForPosition(int position)是根據ListView的position來獲取該位置上面的name的首字母char的ascii值，例如： 如果該position上面的name是阿妹，首字母就是A，那麼此方法返回的就是'A'字母的ascii值，也就是65， 'B'是66，依次類推
getPositionForSection(int section)就是根據首字母的ascii值來獲取在該ListView中第一次出現該首字母的位置，例如：從上面的效果圖1中，如果section是66 ，也就是‘B’的ascii值，那麼該方法返回的position就是2
然後就是getView()方法，首先我們根據ListView的position呼叫getSectionForPosition(int position)來獲取該位置上面name的首字母的ascii值,然後根據這個ascii值呼叫getPositionForSection(int section)來獲取第一次出現該首字母的position，如果ListView的position 等於 根據這個ascii值呼叫getPositionForSection(int section)來獲取第一次出現該首字母的position，則顯示分類字母
