Android實(shí)現(xiàn)通用篩選欄

來源：本站原創(chuàng)|時(shí)間：2020-01-10|欄目：Android|點(diǎn)擊：次

今天來寫一個(gè)通用的篩選欄的實(shí)現(xiàn),也是因?yàn)橹绊?xiàng)目中要好多地方用到篩選欄這么個(gè)東西,所以為了之后用起來比較方便,就簡(jiǎn)單的做了一些封裝.廢話不多說,看一下效果圖:

很多APP都有用到這個(gè)篩選欄,相信大家也不陌生.

一、需求分析

看到這個(gè)篩選欄之后,先來考慮一下布局,在開始接觸android時(shí)候的我,可能看到這個(gè)布局的想法是:篩選欄這個(gè)部分,一個(gè)LinearLayout的橫向布局,然后再分為3個(gè)部分,每個(gè)部分各占比重為1,然后在每個(gè)部分中放一個(gè)TextView和ImageView,之后監(jiān)聽每個(gè)部分的點(diǎn)擊事件,對(duì)TextView和ImageView進(jìn)行顏色、文字、方向等的處理.確實(shí),這樣做能實(shí)現(xiàn)功能,不過寫起來很麻煩,需要手動(dòng)的去處理TextView和ImageView的變化,可能篩選欄多了之后就會(huì)亂掉,而且還要花費(fèi)大量時(shí)間去查找修改BUG,可能有一個(gè)小地方寫反了,效果就亂掉了.

所以思考一下,對(duì)于篩選欄這個(gè)部分,有沒有更好的布局設(shè)計(jì)呢?翻了翻能用的控件,發(fā)現(xiàn)CheckBox其實(shí)用在這里很好用(之前可能對(duì)于CheckBox的用法,只停留在勾選個(gè)對(duì)勾這樣),怎么說它好用呢,因?yàn)镃heckBox有兩種狀態(tài)(選中和未選中)剛好可以符合需求,選中的時(shí)候?qū)⒆煮w顏色變?yōu)樗{(lán)色,并且將圖標(biāo)轉(zhuǎn)換方向和顏色,未選中時(shí)重置為起始的樣式,并且可以通過設(shè)置selector輕松的完成樣式的轉(zhuǎn)變.只需管理CheckBox的狀態(tài)即可.

對(duì)于彈出框,很簡(jiǎn)單,自定義一個(gè)popWindow就可以了.不過需要注意的是因?yàn)樾枰趶椏驈棾龅臅r(shí)候,改變背景色的透明度,并且在彈出框消失之后恢復(fù)背景色的透明度,所以需要做一些特殊處理,這里打算去監(jiān)聽popWindow的變化來去完成相關(guān)處理.

二、代碼實(shí)現(xiàn)及優(yōu)化

根據(jù)上邊的分析,布局設(shè)計(jì)如下:

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
 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"
 tools:context="com.example.junweiliu.filterdemo.MainActivity">

 <!--篩選欄-->
 <LinearLayout
  android:id="@+id/ll_stay_visit_selsect"
  android:layout_width="match_parent"
  android:layout_height="40dp"
  android:background="@color/white"
  android:gravity="center_vertical"
  android:orientation="horizontal">
 <!--篩選地點(diǎn)-->
 <LinearLayout
  android:id="@+id/ll_place_tab"
  android:layout_width="0dp"
  android:layout_height="match_parent"
  android:layout_weight="1"
  android:gravity="center">
  <CheckBox
   android:id="@+id/cb_place"
   android:layout_width="wrap_content"
   android:layout_height="wrap_content"
   android:background="@null"
   android:button="@null"
   android:drawablePadding="10dp"
   android:drawableRight="@drawable/seletor_stock_arrow"
   android:gravity="center"
   android:text="地點(diǎn)"
   android:textColor="@drawable/selector_text_stock"
   android:textSize="15sp"/>
 </LinearLayout>
 <!--篩選類型-->
 <LinearLayout
  android:id="@+id/ll_type"
  android:layout_width="0dp"
  android:layout_height="match_parent"
  android:layout_weight="1"
  android:gravity="center">
  <CheckBox
   android:id="@+id/cb_type"
   android:layout_width="wrap_content"
   android:layout_height="wrap_content"
   android:background="@null"
   android:button="@null"
   android:drawablePadding="10dp"
   android:drawableRight="@drawable/seletor_stock_arrow"
   android:gravity="center"
   android:text="條件"
   android:textColor="@drawable/selector_text_stock"
   android:textSize="15sp"/>
 </LinearLayout>
 <!--篩選時(shí)間-->
 <LinearLayout
  android:id="@+id/ll_time"
  android:layout_width="0dp"
  android:layout_height="match_parent"
  android:layout_weight="1"
  android:gravity="center">
  <CheckBox
   android:id="@+id/cb_time"
   android:layout_width="wrap_content"
   android:layout_height="wrap_content"
   android:background="@null"
   android:button="@null"
   android:drawablePadding="10dp"
   android:drawableRight="@drawable/seletor_stock_arrow"
   android:gravity="center"
   android:text="時(shí)間"
   android:textColor="@drawable/selector_text_stock"
   android:textSize="15sp"/>
 </LinearLayout>
 </LinearLayout>
</RelativeLayout>

設(shè)置了3部分,并且每個(gè)部分都使用CheckBox,CheckBox中設(shè)置了兩個(gè)selector,分別是android:drawableRight=”@drawable/seletor_stock_arrow” 和android:textColor=”@drawable/selector_text_stock”

設(shè)置如下:

設(shè)置箭頭樣式的seletor_stock_arrow:

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
 <!--選中的箭頭樣式-->
 <item android:drawable="@mipmap/arrow_up_blue" android:state_checked="true" />
 <!--未選中的箭頭樣式-->
 <item android:drawable="@mipmap/arrow_down_black" android:state_checked="false" />
</selector>

設(shè)置文字樣式的selector_text_stock:

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
 <item android:color="@color/gray" android:state_checked="false" />
 <item android:color="@color/colorPrimary" android:state_checked="true" />
</selector>

實(shí)現(xiàn)很簡(jiǎn)單,來看一下效果:

效果還不錯(cuò),接下來就是在代碼中去管理每個(gè)CheckBox的狀態(tài)就可以了.在做這部分之前,先來搞定popWindow,后續(xù)需要配合CheckBox來使用.

popWindow很簡(jiǎn)單,繼承PopupWindow,然后自定義一些樣式和布局即可,直接放代碼:

接下來就是調(diào)用popWindow,在那調(diào)用這個(gè)popWinow比較好呢,因?yàn)橐獙懸粋€(gè)通用的篩選欄,所以把這些公共的部分都提取出來,放到BaseActivity中,需要用到的Activity直接繼承BaseActivity,方便之后使用.

創(chuàng)建一個(gè)BaseActivity并在其中對(duì)popWindow進(jìn)行處理,代碼如下

BaseActivity:

package com.example.junweiliu.filterdemo;

import android.app.Activity;
import android.os.Bundle;
import android.support.annotation.Nullable;
import android.support.v7.app.AppCompatActivity;
import android.view.View;
import android.view.WindowManager;
import android.widget.AdapterView;
import android.widget.PopupWindow;

import com.example.junweiliu.filterdemo.pop.CommonFilterPop;

import java.util.List;

/**
 * Created by junweiliu on 16/11/7.
 */
public class BaseActivity extends AppCompatActivity {

 /**
 * 篩選pop
 */
 private CommonFilterPop mPopupWindow;
 /**
 * 當(dāng)前上下文實(shí)例
 */
 protected Activity activity;

 @Override
 protected void onCreate(@Nullable Bundle savedInstanceState) {
 super.onCreate(savedInstanceState);
 this.activity = this;
 }

 /**
 * 列表選擇popupWindow
 *
 * @param parentView 父View
 * @param itemTexts  列表項(xiàng)文本集合
 * @param itemClickListener 列表項(xiàng)點(diǎn)擊事件
 */
 public void showFilterPopupWindow(View parentView,
     List<String> itemTexts,
     AdapterView.OnItemClickListener itemClickListener,
     CustomerDismissListener dismissListener) {
 showFilterPopupWindow(parentView, itemTexts, itemClickListener, dismissListener, 0);
 }

 /**
 * 列表選擇popupWindow
 *
 * @param parentView 父View
 * @param itemTexts  列表項(xiàng)文本集合
 * @param itemClickListener 列表項(xiàng)點(diǎn)擊事件
 * @param alpha  背景透明度 
 */
 public void showFilterPopupWindow(View parentView,
     List<String> itemTexts,
     AdapterView.OnItemClickListener itemClickListener,
     CustomerDismissListener dismissListener, float alpha) {

 // 判斷當(dāng)前是否顯示
 if (mPopupWindow != null && mPopupWindow.isShowing()) {
  mPopupWindow.dismiss();
  mPopupWindow = null;
 }
 mPopupWindow = new CommonFilterPop(activity, itemTexts);
 mPopupWindow.setOnDismissListener(dismissListener);
 // 綁定篩選點(diǎn)擊事件
 mPopupWindow.setOnItemSelectedListener(itemClickListener);
 // 如果透明度設(shè)置為0的話,則默認(rèn)設(shè)置為0.6f
 if (0 == alpha) {
  alpha = 0.6f;
 }
 // 設(shè)置背景透明度
 WindowManager.LayoutParams lp = activity.getWindow().getAttributes();
 lp.alpha = alpha;
 activity.getWindow().setAttributes(lp);
 // 顯示pop
 mPopupWindow.showAsDropDown(parentView);

 }

 /**
 * 自定義OnDismissListener
 */
 public class CustomerDismissListener implements PopupWindow.OnDismissListener {
 @Override
 public void onDismiss() {
  // 當(dāng)pop消失的時(shí)候,重置背景色透明度
  WindowManager.LayoutParams lp = activity.getWindow().getAttributes();
  lp.alpha = 1.0f;
  activity.getWindow().setAttributes(lp);
 }
 }

 /**
 * 隱藏pop
 */
 public void hidePopListView() {
 // 判斷當(dāng)前是否顯示,如果顯示則dismiss
 if (mPopupWindow != null && mPopupWindow.isShowing()) {
  mPopupWindow.dismiss();
  mPopupWindow = null;
 }
 }
}

在BaseActivity中對(duì)popWindow的顯示消失做了處理,在popWindow創(chuàng)建時(shí),改變了背景的透明度,重寫了CustomerDismissListener來處理popWindow消失時(shí)恢復(fù)背景透明度.

搞定了popWindow之后,就來結(jié)合CheckBox來使用吧.使用時(shí)應(yīng)該是這樣:

// cb1操作
cb1.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
  @Override
  public void onCheckedChanged(CompoundButton compoundButton, boolean b) {
  // 將其他的cb設(shè)置為未選中,將自己設(shè)置為選中
  cb1.setChecked(true);
  cb2.setChecked(false);
  cb3.setChecked(false);
  showFilterPopupWindow(showView, showMes1, new AdapterView.OnItemClickListener() {
    @Override
    public void onItemClick(AdapterView<?> adapterView, View view, int i, long l) {
    cb1.setText(showMes1.get(position));
    }
   },
   new CustomerDismissListener(){
    @Override
    public void onDismiss() {
    super.onDismiss();
    // 消失的時(shí)候,需要將當(dāng)前的cb設(shè)置為未選中
    cb1.setChecked(false);
    }
   });
  }
 });

 // cb2操作
 cb2.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
  @Override
  public void onCheckedChanged(CompoundButton compoundButton, boolean b) {
  // 將其他的cb設(shè)置為未選中,將自己設(shè)置為選中
  cb2.setChecked(true);
  cb1.setChecked(false);
  cb3.setChecked(false);
  showFilterPopupWindow(showView, showMes2, new AdapterView.OnItemClickListener() {
    @Override
    public void onItemClick(AdapterView<?> adapterView, View view, int i, long l) {
    cb2.setText(showMes1.get(position));
    }
   },
   new CustomerDismissListener(){
    @Override
    public void onDismiss() {
    super.onDismiss();
    // 消失的時(shí)候,需要將當(dāng)前的cb設(shè)置為未選中
    cb2.setChecked(false);
    }
   });
  }
 });
 // cb3操作
 cb3.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
  @Override
  public void onCheckedChanged(CompoundButton compoundButton, boolean b) {
  // 將其他的cb設(shè)置為未選中,將自己設(shè)置為選中
  cb3.setChecked(true);
  cb1.setChecked(false);
  cb2.setChecked(false);
  showFilterPopupWindow(showView, showMes3, new AdapterView.OnItemClickListener() {
    @Override
    public void onItemClick(AdapterView<?> adapterView, View view, int i, long l) {
    cb3.setText(showMes3.get(position));
    }
   },
   new CustomerDismissListener(){
    @Override
    public void onDismiss() {
    super.onDismiss();
    // 消失的時(shí)候,需要將當(dāng)前的cb設(shè)置為未選中
    cb3.setChecked(false);
    }
   });
  }
 });

有很多重復(fù)的部分,比如在onDismiss方法中,都是將當(dāng)前cb設(shè)置為未選中狀態(tài),還有初始化選中狀態(tài)部分,代碼冗余太多,所以來封裝一下,在BaseActivity當(dāng)中封裝一個(gè)方法

 /**
 * Tab篩選欄切換
 *
 * @param isChecked  選中狀態(tài)
 * @param showView  展示pop的跟布局
 * @param showMes  展示選擇的數(shù)據(jù)
 * @param itemClickListener 點(diǎn)擊回調(diào)
 * @param tabs  所有的cb(需要幾個(gè)輸入幾個(gè)就可以,cb1,cb2....)
 */
 public void filterTabToggle(boolean isChecked, View showView, List<String> showMes, AdapterView.OnItemClickListener itemClickListener, final CheckBox... tabs) {
 if (isChecked) {
  if (tabs.length <= 0) {
  return;
  }
  // 第一個(gè)checkBox為當(dāng)前點(diǎn)擊選中的cb,其他cb進(jìn)行setChecked(false);
  for (int i = 1; i < tabs.length; i++) {
  tabs[i].setChecked(false);
  }

  showFilterPopupWindow(showView, showMes, itemClickListener, new CustomerDismissListener() {
  @Override
  public void onDismiss() {
   super.onDismiss();
   // 當(dāng)pop消失時(shí)對(duì)第一個(gè)cb進(jìn)行.setChecked(false)操作
   tabs[0].setChecked(false);
  }
  });
 } else {
  // 關(guān)閉checkBox時(shí)直接隱藏popuwindow
  hidePopListView();
 }
}

考慮到通用性,用了不定長參數(shù)… ,之前用過List,不過用起來不太好用,每次使用的時(shí)候,都需要?jiǎng)?chuàng)建list然后去組裝一個(gè)list,用起來怪麻煩的.這樣使用的時(shí)候只需要把需要選中的cb放在不定長參數(shù)的第一位,其他需要設(shè)置未選中的cb放在之后即可.用一下:

// cb操作
cb1.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
  @Override
  public void onCheckedChanged(CompoundButton compoundButton, boolean isChecked) {
  filterTabToggle(isChecked, showView, showMes1, new AdapterView.OnItemClickListener() {
   @Override
   public void onItemClick(AdapterView<?> adapterView, View view, int position, long l) {
   hidePopListView();
   cb1.setText(showMes1.get(position));
   }
  }, cb1, cb2, cb3);
  }
 });

用起來舒服了很多,可之后又發(fā)現(xiàn)了一個(gè)比較尷尬的問題.就是需要傳入的showMes需要是一個(gè)List< String >,有的時(shí)候得到的數(shù)據(jù)并不是一個(gè)字符串類型的List,可能是各種類型的List< Bean >,這腫么辦?解決方法有很多,比如可以這樣做:

 /**
 * 展示時(shí)間的數(shù)據(jù)
 */
 List<TimeBean> mTimes = new ArrayList<>();
 /**
 * 展示的時(shí)間str集合
 */
 List<String> mTimeStr = new ArrayList<>();

 /**
 * 篩選數(shù)據(jù)
 */ 
 public void forMatData(){
 // 初始化時(shí)間
 TimeBean timeBean1 = new TimeBean("1天內(nèi)", "去玩");
 TimeBean timeBean2 = new TimeBean("3天內(nèi)", "去購物");
 TimeBean timeBean3 = new TimeBean("10天內(nèi)", "去旅行");
 TimeBean timeBean4 = new TimeBean("30天內(nèi)", "去賺錢");
 mTimes.add(timeBean1);
 mTimes.add(timeBean2);
 mTimes.add(timeBean3);
 mTimes.add(timeBean4);
 // 獲取時(shí)間中可用于篩選的數(shù)據(jù)
 for (TimeBean bean : mTimes) {
  mTimeStr.add(bean.getTimeStr());
 }
 }

可以從數(shù)據(jù)源中提取出用到的數(shù)據(jù)showMes,也不太麻煩,不過有沒有更好的辦法呢.畢竟每次都從不同的數(shù)據(jù)源中提取這些數(shù)據(jù),也怪費(fèi)時(shí)間的,考慮到這些之后,思來想去,想到一個(gè)不錯(cuò)的方法,使用通配符?,首先提出來一個(gè)公共接口BaseFilter,在其中規(guī)定一個(gè)統(tǒng)一的獲取篩選字段的方法,如下:

package com.example.junweiliu.filterdemo.bean;

/**
 * Created by junweiliu on 16/11/22.
 */
public interface BaseFilter {

 /**
 * 獲取篩選的
 * @return
 */
 public String getFilterStr();
}

然后讓需要用到篩選功能的Bean實(shí)現(xiàn)這個(gè)接口中的getFilterStr方法并且去實(shí)現(xiàn)它.再對(duì)之前的filterTabToggle方法做一下修改,如下:

Bean:

package com.example.junweiliu.filterdemo.bean;

/**
 * Created by junweiliu on 16/11/22.
 */
public class TimeBean implements BaseFilter{
 /**
 * 時(shí)間str
 */
 String timeStr;
 /**
 * 時(shí)間事件
 */
 String timeEvent;

 public TimeBean(String timeStr, String timeEvent) {
 this.timeStr = timeStr;
 this.timeEvent = timeEvent;
 }

 public String getTimeStr() {
 return timeStr;
 }

 public void setTimeStr(String timeStr) {
 this.timeStr = timeStr;
 }

 public String getTimeEvent() {
 return timeEvent;
 }

 public void setTimeEvent(String timeEvent) {
 this.timeEvent = timeEvent;
 }

 @Override
 public String getFilterStr() {
 return timeStr;
 }
}

filterTabToggleT方法:

 /**
 * Tab篩選欄切換
 *
 * @param isChecked  選中狀態(tài)
 * @param showView  展示pop的跟布局
 * @param showMes  展示選擇的數(shù)據(jù)源
 * @param itemClickListener 點(diǎn)擊回調(diào)
 * @param tabs  所有的cb(需要幾個(gè)輸入幾個(gè)就可以,cb1,cb2....)
 */
 public void filterTabToggleT(boolean isChecked, View showView, List<? extends BaseFilter> showMes, AdapterView.OnItemClickListener itemClickListener, final CheckBox... tabs) {
 if (isChecked) {
  if (tabs.length <= 0) {
  return;
  }
  // 第一個(gè)checkBox為當(dāng)前點(diǎn)擊選中的cb,其他cb進(jìn)行setChecked(false);
  for (int i = 1; i < tabs.length; i++) {
  tabs[i].setChecked(false);
  }
  // 從數(shù)據(jù)源中提取出展示的篩選條件
  List<String> showStr = new ArrayList<>();
  for (BaseFilter baseFilter : showMes) {
  showStr.add(baseFilter.getFilterStr());
  }
  showFilterPopupWindow(showView, showStr, itemClickListener, new CustomerDismissListener() {
  @Override
  public void onDismiss() {
   super.onDismiss();
   // 當(dāng)pop消失時(shí)對(duì)第一個(gè)cb進(jìn)行.setChecked(false)操作
   tabs[0].setChecked(false);
  }
  });
 } else {
  // 關(guān)閉checkBox時(shí)直接隱藏popuwindow
  hidePopListView();
 }
 }

這樣在使用的時(shí)候,直接將List< Bean > 類型的數(shù)據(jù)傳進(jìn)去就可以了.這樣整個(gè)的通用的篩選欄就實(shí)現(xiàn)了.當(dāng)然根據(jù)需求的不同,需要去做修改 ,不過大體的思路及實(shí)現(xiàn)就是這樣.之后就可以這樣用:

// 選擇時(shí)間cb
 mTimeCb.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
  @Override
  public void onCheckedChanged(CompoundButton compoundButton, boolean isChecked) {
  filterTabToggleT(isChecked, mTimeAll, mTimes, new AdapterView.OnItemClickListener() {
   @Override
   public void onItemClick(AdapterView<?> adapterView, View view, int position, long l) {
   hidePopListView();
   mTimeCb.setText(mTimeStr.get(position));
   }
  }, mTimeCb, mPlaceCb, mTypeCb);
  }
 });
