Android编程实现仿QQ发表说说，上传照片及弹出框效果【附demo源码下载】

本文实例讲述了android编程实现仿qq发表说说，上传照片及弹出框效果。分享给大家供大家参考，具体如下：

代码很简单,主要就是几个动画而已,图标什么的就随便找了几个,效果图:

 

动画说明:

1.点击右上角按钮,菜单从顶部下拉弹出,同时背景变暗;
2.再次点击右上角按钮,点击返回键,或者点击空白区域(也就是变暗的部分),菜单向上收回;
3.点击菜单上的按钮响应事件,同时菜单收回(效果同2)

重要说明：动画结束后必须clearanimation，否则隐藏状态的view依然能响应点击事件

主体代码:

public class mainactivity extends activity {
  //添加数据按钮
  private imageview adddataiv;
  //下拉功能菜单
  private linearlayout dropdownview;
  private view bgview;
  //当前下拉菜单是否为显示状态
  private boolean showitems = false;
  @override
  protected void oncreate(bundle savedinstancestate) {
    super.oncreate(savedinstancestate);
    setcontentview(r.layout.activity_main);
    adddataiv = (imageview) findviewbyid(r.id.main_newdata);
    dropdownview = (linearlayout) findviewbyid(r.id.dropdownview);
    bgview = findviewbyid(r.id.main_bg);
    adddataiv.setonclicklistener(new view.onclicklistener() {
      @override
      public void onclick(view v) {
        if (!showitems) {
          showview();
        } else {
          dismissview();
        }
      }
    });
    //点击空白隐藏弹出框
    bgview.setonclicklistener(new view.onclicklistener() {
      @override
      public void onclick(view v) {
        if (showitems) {
          dismissview();
        }
      }
    });
    //下拉功能菜单上按钮的点击事件
    view.onclicklistener l = new onclickimpl();
    findviewbyid(r.id.dropdown_item1).setonclicklistener(l);
    findviewbyid(r.id.dropdown_item2).setonclicklistener(l);
    findviewbyid(r.id.dropdown_item3).setonclicklistener(l);
    findviewbyid(r.id.dropdown_item4).setonclicklistener(l);
  }
  //显示下拉菜单
  private void showview() {
    showitems = true;
    adddataiv.startanimation(animationutils.loadanimation(mainactivity.this, r.anim.rotate_open));
    dropdownview.startanimation(animationutils.loadanimation(this, r.anim.drop_down));
    dropdownview.setvisibility(view.visible);
    bgview.startanimation(animationutils.loadanimation(mainactivity.this, r.anim.fade_dark));
    bgview.setvisibility(view.visible);
  }
  //隐藏下拉菜单
  private void dismissview() {
    showitems = false;
    adddataiv.startanimation(animationutils.loadanimation(mainactivity.this, r.anim.rotate_close));
    animation dropupanim = animationutils.loadanimation(this, r.anim.drop_up);
    dropupanim.setanimationlistener(new animlistenerimpl(dropdownview));
    dropdownview.startanimation(dropupanim);
    dropdownview.setvisibility(view.invisible);
    animation fadelightanim = animationutils.loadanimation(mainactivity.this, r.anim.fade_light);
    fadelightanim.setanimationlistener(new animlistenerimpl(bgview));
    bgview.startanimation(fadelightanim);
    bgview.setvisibility(view.invisible);
  }
  //点击返回键时，如果下拉菜单是显示状态，则隐藏它
  @override
  public void onbackpressed() {
    if (showitems) {
      dismissview();
      return;
    }
    super.onbackpressed();
  }
  private class onclickimpl implements view.onclicklistener {
    @override
    public void onclick(view v) {
      if (!showitems) {
        return;
      }
      int id = v.getid();
      switch (id) {
        case r.id.dropdown_item1:
          toast.maketext(mainactivity.this, "item1 onclick", toast.length_short).show();
          dismissview();
          break;
        case r.id.dropdown_item2:
          toast.maketext(mainactivity.this, "item2 onclick", toast.length_short).show();
          dismissview();
          break;
        case r.id.dropdown_item3:
          toast.maketext(mainactivity.this, "item3 onclick", toast.length_short).show();
          dismissview();
          break;
        case r.id.dropdown_item4:
          toast.maketext(mainactivity.this, "item4 onclick", toast.length_short).show();
          dismissview();
          break;
        default:
          break;
      }
    }
  }
  //动画结束后必须clearanimation，否则隐藏状态的view依然能响应点击事件
  private class animlistenerimpl implements animation.animationlistener {
    private view view;
    public animlistenerimpl(view view) {
      this.view = view;
    }
    @override
    public void onanimationstart(animation animation) {
    }
    @override
    public void onanimationend(animation animation) {
      view.clearanimation();
    }
    @override
    public void onanimationrepeat(animation animation) {
    }
