Android实现底部弹窗效果

本文实例为大家分享了android实现底部弹窗效果的具体代码，供大家参考，具体内容如下

源代码地址：https://github.com/luoye123/box

东西很简单，我就直接亮代码了：

1、activity_main.xml

<?xml version="1.0" encoding="utf-8"?>
<linearlayout
 xmlns:android="http://schemas.android.com/apk/res/android"
 android:layout_width="fill_parent"
 android:layout_height="fill_parent"
 android:gravity="center"
 android:id="@+id/ll_image">

 <button
 android:id="@+id/bt_select_image"
 android:layout_width="wrap_content"
 android:layout_height="wrap_content"
 android:text="选择图片" />
</linearlayout>

2、mainactivity.java

public class mainactivity extends appcompatactivity implements view.onclicklistener {

 private selectpicpopupwindow menuwindow;

 @override
 protected void oncreate(bundle savedinstancestate) {
 super.oncreate(savedinstancestate);
 setcontentview(r.layout.activity_main);
 findviewbyid(r.id.bt_select_image).setonclicklistener(this);
 }

 @override
 public void onclick(view view) {
 switch (view.getid()) {
  case r.id.bt_select_image:
  //todo implement
  selectimgs();
 }
 }
 private void selectimgs(){

 menuwindow = new selectpicpopupwindow(mainactivity.this, itemsonclick);
 //设置弹窗位置
 menuwindow.showatlocation(mainactivity.this.findviewbyid(r.id.ll_image), gravity.bottom | gravity.center_horizontal, 0, 0);
 }

 private view.onclicklistener itemsonclick = new view.onclicklistener() {
 public void onclick(view v) {
  menuwindow.dismiss();
  switch (v.getid()) {
  case r.id.item_popupwindows_camera: //点击拍照按钮

   break;
  case r.id.item_popupwindows_photo: //点击从相册中选择按钮


   break;
  default:
   break;
  }
 }

 };
}

3、关键代码：selectpicpopupwindow.java

 **public class selectpicpopupwindow extends popupwindow {

  private button item_popupwindows_camera, //弹窗拍照按钮
   item_popupwindows_photo,  //弹窗从相册选择按钮
   item_popupwindows_cancel;  //弹窗取消按钮
  private view menuview;

  /**
  * 上传图片*************************
  * @param context
  * @param itemsonclick
  */
  public selectpicpopupwindow(activity context, view.onclicklistener itemsonclick){
  super(context);
  layoutinflater inflater = (layoutinflater) context.getsystemservice(context.layout_inflater_service);
  menuview = inflater.inflate(r.layout.item_popupwindows,null);
  item_popupwindows_camera = (button) menuview.findviewbyid(r.id.item_popupwindows_camera); //拍照按钮
  item_popupwindows_cancel = (button) menuview.findviewbyid(r.id.item_popupwindows_cancel); //取消按钮
  item_**popupwindows_photo = (button) menuview.findviewbyid(r.id.item_popupwindows_photo); //图库按钮

  /**
   * 取消按钮销毁事件
   */
  item_popupwindows_cancel.setonclicklistener(new view.onclicklistener() {
   public void onclick(view view) {
   dismiss();
   }
  });
  item_popupwindows_camera.setonclicklistener(itemsonclick);
  item_popupwindows_photo.setonclicklistener(itemsonclick);
  //设置selectpicpopupwindow的view
  this.setcontentview(menuview);
  //设置selectpicpopupwindow**弹出窗体的宽
  this.setwidth(viewgroup.layoutparams.fill_parent);
  //设置selectpicpopupwindow弹出窗体的高
  //修改高度显示，解决被手机底部虚拟键挡住的问题 by黄海杰 at:2015-4-30
  this.setheight(viewgroup.layoutparams.match_parent);
  //设置selectpicpopupwindow弹出窗体可点击
  this.setfocusable(true);
  //设置selectpicpopupwindow弹出窗体动画效果
  //this.setanimationstyle(r.style);
  //实例化一个colordrawable颜色为半透明
  colordrawable dw = new colordrawable(0xb0000000);
  //设置selectpicpopupwindow弹出窗体的背景
  this.setbackgrounddrawable(dw);
  //menuview添加ontouchlistener监听判断获取触屏位置如果在选择框外面则销毁弹出框
  menuview.setontouchlistener(new view.ontouchlistener() {
   public boolean ontouch(view view, motionevent motionevent) {
   int height = menuview.findviewbyid(r.id.ll_popup).gettop();
   int y = (int) motionevent.gety();
   if (motionevent.getaction() == motionevent.action_up){
    if (y<height){
    dismiss();
    }
   }
   return true;
   }
  });
  }
 }**
