這裡分享一個Android的非常經典實用而且簡單方便的第三方UI控制項陳列庫:BottomView(小米的米UI也用到了這個)
實現功能:
可以在底部彈出的View裡自訂布局;
可以自訂是否可以觸摸外部消失;
可以自訂事件;
可以自訂外圍背景是否透明;
可以自訂動畫;
如果需要的話,可以強製為頂部View顯示

package com.tandong.bottomview.view;import android.app.Dialog;import android.content.Context;import android.view.Display;import android.view.View;import android.view.Window;import android.view.WindowManager;public class BottomView { private View convertView; private Context context; private int theme; private Dialog bv; private int animationStyle; private boolean isTop = false; public BottomView(Context c, int theme, View convertView) { this.theme = theme; this.context = c; this.convertView = convertView; } public BottomView(Context c, int theme, int resource) { this.theme = theme; this.context = c; this.convertView = View.inflate(c, resource, null); } public void showBottomView(boolean CanceledOnTouchOutside) { if (this.theme == 0) this.bv = new Dialog(this.context); else this.bv = new Dialog(this.context, this.theme); this.bv.setCanceledOnTouchOutside(CanceledOnTouchOutside); this.bv.getWindow().requestFeature(1); this.bv.setContentView(this.convertView); Window wm = this.bv.getWindow(); WindowManager m = wm.getWindowManager(); Display d = m.getDefaultDisplay(); WindowManager.LayoutParams p = wm.getAttributes(); p.width = (d.getWidth() * 1); if (this.isTop) p.gravity = 48; else p.gravity = 80; if (this.animationStyle != 0) { wm.setWindowAnimations(this.animationStyle); } wm.setAttributes(p); this.bv.show(); } public void setTopIfNecessary() { this.isTop = true; } public void setAnimation(int animationStyle) { this.animationStyle = animationStyle; } public View getView() { return this.convertView; } public void dismissBottomView() { if (this.bv != null) this.bv.dismiss(); }}
用法:
1、下載BottomView.jar庫檔案,放到Android項目工程裡的libs裡
2、設定BottomView的Theme:
這2個Theme複製粘貼到你的項目的res/values/styles.xml裡即可
view sourceprint?01.<!--半透明背景Theme-->02.<style name="BottomViewTheme_Defalut">03.<item name="android:windowFrame">@null</item>04.<item name="android:windowContentOverlay">@null</item>05.<item name="android:windowIsFloating">true</item>06.<item name="android:windowIsTranslucent">false</item>07.<item name="android:windowNoTitle">true</item>08.<item name="android:windowBackground">@color/white</item>09.<item name="android:backgroundDimEnabled">true</item>10.<item name="android:windowFullscreen">true</item>11.</style>12.<!--透明背景Theme-->13.<style name="BottomViewTheme_Transparent">14.<item name="android:windowFrame">@null</item>15.<item name="android:windowIsFloating">true</item>16.<!-- Transparent -->17.<item name="android:windowIsTranslucent">false</item>18.<item name="android:windowContentOverlay">@null</item>19.<item name="android:windowNoTitle">true</item>20.<item name="android:windowBackground">@color/white</item>21.<item name="android:backgroundDimEnabled">false</item>22.</style>另外如果提示
view sourceprint?1.<item name="android:windowBackground">@color/white</item>這裡的white找不到的話,說明你項目res/values/color.xml沒有建立或者沒有white顏色這個值,只需在res/values/color.xml裡添加
view sourceprint?1.<color name="white">#ffffff</color>
這個白色值即可。
另外View的動畫Theme可選,建議也複製進去,效果好一些,代碼如下:
view sourceprint?1.<style name="BottomToTopAnim" parent="android:Animation">2.<item name="@android:windowEnterAnimation">@anim/bottomview_anim_enter</item>3.<item name="@android:windowExitAnimation">@anim/bottomview_anim_exit</item>4.</style>
res/anim/bottomview_anim_enter.xml
view sourceprint?1.<?xml version="1.0" encoding="utf-8"?>2.<set xmlns:android="http://schemas.android.com/apk/res/android" >3. 4.<translate5.android:duration="500"6.android:fromYDelta="100%p" />7. 8.</set>
res/anim/bottomview_anim_exit.xml
view sourceprint?1.<?xml version="1.0" encoding="utf-8"?>2.<set xmlns:android="http://schemas.android.com/apk/res/android" >3. 4.<translate5.android:duration="500"6.android:toYDelta="100%p" />7. 8.</set>
整體為:
2、部分核心使用代碼:
view sourceprint?1.BottomView bottomView = new BottomView(this,2.R.style.BottomViewTheme_Defalut, R.layout.bottom_view);3.bottomView.setAnimation(R.style.BottomToTopAnim);//設定動畫,可選4.bottomView.showBottomView(false);
如果想擷取這個View的話,調用.getView()方法即可。
之一:(可隨意發揮)
