在我们的项目开发过程中，经常会对用户的信息进行分组，即通过组来显示用户的信息，同时通过一定的查询条件来显示查询后的相关用户信息，并且通过颜色选择器来设置列表信息的背景颜色。
其中借鉴xiaanming:http://blog.csdn.net/xiaanming/article/details/
下面来看看项目运行后的效果图以及代码结构图：
下面通过代码来实现整个效果。
1.主界面布局activity_main.xml
&span style=&font-size:18&&&LinearLayout xmlns:android=&/apk/res/android&
xmlns:tools=&/tools&
android:layout_width=&match_parent&
android:layout_height=&match_parent&
android:orientation=&vertical&
android:paddingBottom=&@dimen/activity_vertical_margin&
android:paddingLeft=&@dimen/activity_horizontal_margin&
android:paddingRight=&@dimen/activity_horizontal_margin&
android:paddingTop=&@dimen/activity_vertical_margin& &
android:id=&@+id/my_btn&
android:layout_width=&match_parent&
android:layout_height=&wrap_content&
android:text=&生成部门列表& /&
&com.example.myexpandabledemo.ClearEditText
android:id=&@+id/filter_edit&
android:layout_width=&fill_parent&
android:layout_height=&60dp&
android:layout_marginTop=&10dip&
android:background=&@drawable/search_bar_edit_selector&
android:drawableLeft=&@drawable/search_bar_icon_normal&
android:hint=&搜索&
android:singleLine=&true&
android:textSize=&15.0dip& /&
android:id=&@+id/no_search_result_tv&
android:layout_width=&match_parent&
android:layout_height=&wrap_content&
android:text=&未搜索到结果&
android:visibility=&gone&
&ExpandableListView
android:id=&@+id/my_expand_lv&
android:layout_width=&match_parent&
android:layout_height=&wrap_content& /&
&/LinearLayout&&/span&分析：主界面主要有一个Button,一个自定义搜索的ClearEditText，一个无查询结果的TextView,一个列表信息显示ExpandableListView。其中Button主要用来生成列表信息。
2.自定义的ClearEditText的搜索框CliearEditText.java
&span style=&font-size:18&&package com.example.
import android.content.C
import android.graphics.drawable.D
import android.text.E
import android.text.TextW
import android.util.AttributeS
import android.view.MotionE
import android.view.V
import android.view.View.OnFocusChangeL
import android.view.animation.A
import android.view.animation.CycleI
import android.view.animation.TranslateA
import android.widget.EditT
public class ClearEditText extends EditText implements
OnFocusChangeListener, TextWatcher {
* 删除按钮的引用
private Drawable mClearD
public ClearEditText(Context context) {
this(context, null);
public ClearEditText(Context context, AttributeSet attrs) {
//这里构造方法也很重要，不加这个很多属性不能再XML里面定义
this(context, attrs, android.R.attr.editTextStyle);
public ClearEditText(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
private void init() {
//获取EditText的DrawableRight,假如没有设置我们就使用默认的图片
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);
* 因为我们不能直接给EditText设置点击事件，所以我们用记住我们按下的位置来模拟点击事件
* 当我们按下的位置 在
EditText的宽度 - 图标到控件右边的间距 - 图标的宽度
* EditText的宽度 - 图标到控件右边的间距之间我们就算点击了图标，竖直方向没有考虑
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);
* 当ClearEditText焦点发生变化的时候，判断里面字符串长度设置清除图标的显示与隐藏
public void onFocusChange(View v, boolean hasFocus) {
if (hasFocus) {
setClearIconVisible(getText().length() & 0);
setClearIconVisible(false);
* 设置清除图标的显示与隐藏，调用setCompoundDrawables为EditText绘制上去
* @param visible
protected void setClearIconVisible(boolean visible) {
Drawable right = visible ? mClearDrawable :
setCompoundDrawables(getCompoundDrawables()[0],
getCompoundDrawables()[1], right, getCompoundDrawables()[3]);
* 当输入框里面内容发生变化的时候回调的方法
public void onTextChanged(CharSequence s, int start, int count,
int after) {
setClearIconVisible(s.length() & 0);
public void beforeTextChanged(CharSequence s, int start, int count,
int after) {
public void afterTextChanged(Editable s) {
* 设置晃动动画
public void setShakeAnimation(){
this.setAnimation(shakeAnimation(5));
* 晃动动画
* @param counts 1秒钟晃动多少下
public static Animation shakeAnimation(int counts){
Animation translateAnimation = new TranslateAnimation(0, 10, 0, 0);
translateAnimation.setInterpolator(new CycleInterpolator(counts));
translateAnimation.setDuration(1000);
return translateA
搜索框颜色选择器：
&span style=&font-size:18&&&?xml version=&1.0& encoding=&UTF-8&?&
&selector xmlns:android=&/apk/res/android&&
&item android:state_focused=&true& android:drawable=&@drawable/search_bar_edit_pressed&&&/item&
&item android:state_pressed=&true& android:drawable=&@drawable/search_bar_edit_pressed&&&/item&

&/LinearLayout&&/span&分析：根据android:background=&@drawable/my_child_selector& 颜色选择器来设置每个列表行(选中或正常)的背景色。
9.颜色选择器my_child_selector.xml
&span style=&font-size:18&&&?xml version=&1.0& encoding=&UTF-8&?&
&selector xmlns:android=&/apk/res/android&&
&item android:state_focused=&true& android:drawable=&@color/press_color&&&/item&
