編輯:關於Android編程
在我們的項目開發過程中,經常會對用戶的信息進行分組,即通過組來顯示用戶的信息,同時通過一定的查詢條件來顯示查詢後的相關用戶信息,並且通過顏色選擇器來設置列表信息的背景顏色。
下面來看看項目運行後的效果圖以及代碼結構圖:
下面通過代碼來實現整個效果。
1.主界面布局activity_main.xml
分析:主界面主要有一個Button,一個自定義搜索的ClearEditText,一個無查詢結果的TextView,一個列表信息顯示ExpandableListView。其中Button主要用來生成列表信息。
2.自定義的ClearEditText的搜索框CliearEditText.java
package com.example.myexpandabledemo; import android.content.Context; import android.graphics.drawable.Drawable; import android.text.Editable; import android.text.TextWatcher; import android.util.AttributeSet; import android.view.MotionEvent; import android.view.View; import android.view.View.OnFocusChangeListener; import android.view.animation.Animation; import android.view.animation.CycleInterpolator; import android.view.animation.TranslateAnimation; import android.widget.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,假如沒有設置我們就使用默認的圖片 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設置點擊事件,所以我們用記住我們按下的位置來模擬點擊事件 * 當我們按下的位置 在 EditText的寬度 - 圖標到控件右邊的間距 - 圖標的寬度 和 * EditText的寬度 - 圖標到控件右邊的間距之間我們就算點擊了圖標,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,判斷裡面字符串長度設置清除圖標的顯示與隱藏 */ @Override public void onFocusChange(View v, boolean hasFocus) { if (hasFocus) { setClearIconVisible(getText().length() > 0); } else { setClearIconVisible(false); } } /** * 設置清除圖標的顯示與隱藏,調用setCompoundDrawables為EditText繪制上去 * @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調的方法 */ @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) { } /** * 設置晃動動畫 */ 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; } }
搜索框顏色選擇器:
3.漢字拼音排序所需要的漢字轉拼音:CharacterParser.java
package com.example.myexpandabledemo; /** * Java漢字轉換為拼音 * */ public class CharacterParser { private static int[] pyvalue = new int[] {-20319, -20317, -20304, -20295, -20292, -20283, -20265, -20257, -20242, -20230, -20051, -20036, -20032, -20026, -20002, -19990, -19986, -19982, -19976, -19805, -19784, -19775, -19774, -19763, -19756, -19751, -19746, -19741, -19739, -19728, -19725, -19715, -19540, -19531, -19525, -19515, -19500, -19484, -19479, -19467, -19289, -19288, -19281, -19275, -19270, -19263, -19261, -19249, -19243, -19242, -19238, -19235, -19227, -19224, -19218, -19212, -19038, -19023, -19018, -19006, -19003, -18996, -18977, -18961, -18952, -18783, -18774, -18773, -18763, -18756, -18741, -18735, -18731, -18722, -18710, -18697, -18696, -18526, -18518, -18501, -18490, -18478, -18463, -18448, -18447, -18446, -18239, -18237, -18231, -18220, -18211, -18201, -18184, -18183, -18181, -18012, -17997, -17988, -17970, -17964, -17961, -17950, -17947, -17931, -17928, -17922, -17759, -17752, -17733, -17730, -17721, -17703, -17701, -17697, -17692, -17683, -17676, -17496, -17487, -17482, -17468, -17454, -17433, -17427, -17417, -17202, -17185, -16983, -16970, -16942, -16915, -16733, -16708, -16706, -16689, -16664, -16657, -16647, -16474, -16470, -16465, -16459, -16452, -16448, -16433, -16429, -16427, -16423, -16419, -16412, -16407, -16403, -16401, -16393, -16220, -16216, -16212, -16205, -16202, -16187, -16180, -16171, -16169, -16158, -16155, -15959, -15958, -15944, -15933, -15920, -15915, -15903, -15889, -15878, -15707, -15701, -15681, -15667, -15661, -15659, -15652, -15640, -15631, -15625, -15454, -15448, -15436, -15435, -15419, -15416, -15408, -15394, -15385, -15377, -15375, -15369, -15363, -15362, -15183, -15180, -15165, -15158, -15153, -15150, -15149, -15144, -15143, -15141, -15140, -15139, -15128, -15121, -15119, -15117, -15110, -15109, -14941, -14937, -14933, -14930, -14929, -14928, -14926, -14922, -14921, -14914, -14908, -14902, -14894, -14889, -14882, -14873, -14871, -14857, -14678, -14674, -14670, -14668, -14663, -14654, -14645, -14630, -14594, -14429, -14407, -14399, -14384, -14379, -14368, -14355, -14353, -14345, -14170, -14159, -14151, -14149, -14145, -14140, -14137, -14135, -14125, -14123, -14122, -14112, -14109, -14099, -14097, -14094, -14092, -14090, -14087, -14083, -13917, -13914, -13910, -13907, -13906, -13905, -13896, -13894, -13878, -13870, -13859, -13847, -13831, -13658, -13611, -13601, -13406, -13404, -13400, -13398, -13395, -13391, -13387, -13383, -13367, -13359, -13356, -13343, -13340, -13329, -13326, -13318, -13147, -13138, -13120, -13107, -13096, -13095, -13091, -13076, -13068, -13063, -13060, -12888, -12875, -12871, -12860, -12858, -12852, -12849, -12838, -12831, -12829, -12812, -12802, -12607, -12597, -12594, -12585, -12556, -12359, -12346, -12320, -12300, -12120, -12099, -12089, -12074, -12067, -12058, -12039, -11867, -11861, -11847, -11831, -11798, -11781, -11604, -11589, -11536, -11358, -11340, -11339, -11324, -11303, -11097, -11077, -11067, -11055, -11052, -11045, -11041, -11038, -11024, -11020, -11019, -11018, -11014, -10838, -10832, -10815, -10800, -10790, -10780, -10764, -10587, -10544, -10533, -10519, -10331, -10329, -10328, -10322, -10315, -10309, -10307, -10296, -10281, -10274, -10270, -10262, -10260, -10256, -10254};

package com.example.myexpandabledemo; import java.util.Comparator; public class PinyinComparator implements Comparator5. 顯示列表信息的名字以及其拼音首字母 GrouMemberBean.java{ public int compare(GroupMemberBean o1, GroupMemberBean o2) { if (o1.getSortLetters().equals(@) || o2.getSortLetters().equals(#)) { return -1; } else if (o1.getSortLetters().equals(#) || o2.getSortLetters().equals(@)) { return 1; } else { return o1.getSortLetters().compareTo(o2.getSortLetters()); } } }
package com.example.myexpandabledemo; public class GroupMemberBean { private String name; //顯示的數據 private String sortLetters; //顯示數據拼音的首字母 public String getName() { return name; } public void setName(String name) { this.name = name; } public String getSortLetters() { return sortLetters; } public void setSortLetters(String sortLetters) { this.sortLetters = sortLetters; } }6.ExpandaleListView 適配器MyExpandableAdapter.java
package com.example.myexpandabledemo; import java.util.List; import android.content.Context; import android.view.LayoutInflater; import android.view.View; import android.view.View.OnClickListener; import android.view.ViewGroup; import android.widget.BaseExpandableListAdapter; import android.widget.ImageView; import android.widget.LinearLayout; import android.widget.TextView; import android.widget.Toast; public class MyExpandableAdapter extends BaseExpandableListAdapter { private Context mContext; private ListmGroup; private List > mChild; private LayoutInflater mInflater; public MyExpandableAdapter(Context mContext,List

分析:
GroupHolderView:用於顯示組信息
ChildHolderView:用於顯示組下成員信息。包括一個LinearLayout,一個ImageView,一個TextVIew
private List
private List> mChild;包含所有的組下成員信息
public void updateListView(List根據傳入的mGroup,mChild來更新列表信息。mGroup,List > mChild) { this.mGroup = mGroup; this.mChild = mChild; notifyDataSetChanged(); }
7.GroupHolderView類所對應的activity_group.xml
分析:根據android:background=@drawable/my_child_selector 顏色選擇器來設置每個列表行(選中或正常)的背景色。

private List根據 res->array定義的字符數組,轉化為ListfilledData(String[] date)
private void filterData(String filterStr) {根據查詢條件更新列表信息,
假如:filterStr = “g”;
2.如果查詢的結果為空,直接給出“未搜索到結果”提示;
3.如果Group中包含filterStr,GroupMemberBean sortModel 直接加入groupFilterList,並標記已加入isAddGroup = true;
如果Child中包含filterStr,定義臨時的tempFilterList,GroupMemberBean sortChildModel加入到childFilterList,如果groupFilterList不包含其父組,並將其父加入到groupFilterList,並標記已加入isAddGroup=true;
最後如果isAddGroup=true,將tempFilterList加入到childFilterList。
4.通過myAdapter.updateListView(groupFilterList, childFilterList),更新列表信息。

簡介作為Android開發者,我們經常需要自定義控件,比如下面我們說的實現圖片的多點觸控和伸縮釋放,這也是由於用戶已經有這樣的常識了,那就是看見有圖片的地方就可以點擊查看
最近由於項目的需要,自定義了一個具有側滑功能的listview,側滑後可以點擊編輯、刪除。好了,大家先看一下效果圖,畢竟是看臉的世界。 好了,我要先講一下思路,
為延長設備的電池壽命、降低內存使用率以及提升應用性能,Android N 對系統行為做出了一些變更。這些變更可能會影響系統資源和系統通知對應用的可用性。您應仔細檢查這些變
