自定义代码

package com.duanlian.popupwindowdemo; 
 
import android.app.activity; 
import android.content.context; 
import android.graphics.drawable.colordrawable; 
import android.view.layoutinflater; 
import android.view.view;

    super(context); 
    initview(context, itemsonclick); 
  } 
 
  private void initview(final activity context, view.onclicklistener itemsonclick) { 
    layoutinflater minflater = (layoutinflater) context.getsystemservice(context.layout_inflater_service); 
    mview = minflater.inflate(r.layout.popupwindow_share, null); 
    linearlayout weixfriend = (linearlayout) mview.findviewbyid(r.id.weixinghaoyou); 
    linearlayout friendster = (linearlayout) mview.findviewbyid(r.id.pengyouquan);

        //销毁弹出框 
        dismiss(); 
        backgroundalpha(context, 1f); 
      } 
    }); 
    //设置按钮监听 
    weixfriend.setonclicklistener(itemsonclick); 
    friendster.setonclicklistener(itemsonclick); 
    qqfriend.setonclicklistener(itemsonclick); 
    qqzone.setonclicklistener(itemsonclick); 
    //设置selectpicpopupwindow的view 
    this.setcontentview(mview);

    this.setfocusable(true); 
    //设置popupwindow可触摸 
    this.settouchable(true);

    //实例化一个colordrawable颜色为半透明 
    colordrawable dw = new colordrawable(0x00000000); 
    //设置selectpicpopupwindow弹出窗体的背景 
    this.setbackgrounddrawable(dw); 
    backgroundalpha(context, 0.5f);//0.0-1.0 
    this.setondismisslistener(new ondismisslistener() { 
 
      @override 
      public void ondismiss() { 
        // todo auto-generated method stub 
        backgroundalpha(context, 1f); 
      } 
    }); 
  } 
 
 
  /** 
   * 设置添加屏幕的背景透明度 
   * 
   * @param bgalpha 
   */ 
  public void backgroundalpha(activity context, float bgalpha) { 
    windowmanager.layoutparams lp = context.getwindow().getattributes(); 
    lp.alpha = bgalpha; 
    context.getwindow().addflags(windowmanager.layoutparams.flag_dim_behind); 
    context.getwindow().setattributes(lp); 
  } 
 
} 

mainactivity中用

package com.duanlian.popupwindowdemo; 
 
import android.os.bundle; 
import android.support.v7.app.appcompatactivity; 
import android.view.gravity; 
import android.view.view; 
import android.widget.toast; 
 
public class mainactivity extends appcompatactivity { 
  private rewritepopwindow mpopwindow; 
 
  @override 
  protected void oncreate(bundle savedinstancestate) { 
    super.oncreate(savedinstancestate); 
    setcontentview(r.layout.activity_main); 
    findviewbyid(r.id.share).setonclicklistener(new view.onclicklistener() { 
      @override 
      public void onclick(view view) { 
        mpopwindow = new rewritepopwindow(mainactivity.this, itemsonclick); 
        mpopwindow.showatlocation(view, 
            gravity.bottom | gravity.center_horizontal, 0, 0); 
      } 
    }); 
  } 
 
  //为弹出窗口实现监听类 
  private view.onclicklistener itemsonclick = new view.onclicklistener() { 
 
    public void onclick(view v) { 
      mpopwindow.dismiss(); 
      mpopwindow.backgroundalpha(mainactivity.this, 1f); 
      switch (v.getid()) { 
        case r.id.weixinghaoyou: 
          toast.maketext(mainactivity.this, "微信好友", toast.length_short).show(); 
          break; 
        case r.id.pengyouquan: 
          toast.maketext(mainactivity.this, "朋友圈", toast.length_short).show(); 
          break; 
        case r.id.qqhaoyou: 
          toast.maketext(mainactivity.this, "qq好友", toast.length_short).show(); 
          break; 
        case r.id.qqkongjian: 
          toast.maketext(mainactivity.this, "qq空间", toast.length_short).show(); 
          break; 
        default: 
          break; 
      } 
    } 
 
  }; 
}
