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; import androID.vIEw.WindowManager; import androID.Widget.linearLayout; import androID.Widget.PopupWindow; import androID.Widget.TextVIEw;  /**  * 自定义popupWindow  */  public class RewritePopwindow extends PopupWindow {   private VIEw mVIEw;    public RewritePopwindow(Activity context,VIEw.OnClickListener itemsOnClick) {     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);     linearLayout QQFrIEnd = (linearLayout) mVIEw.findVIEwByID(R.ID.qqhaoyou);     linearLayout QQZone = (linearLayout) mVIEw.findVIEwByID(R.ID.qqkongjian);     TextVIEw canaleTv = (TextVIEw) mVIEw.findVIEwByID(R.ID.share_cancle);     canaleTv.setonClickListener(new VIEw.OnClickListener() {       @OverrIDe       public voID onClick(VIEw v) {          //销毁d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);     //设置SelectPicPopupWindowd出窗体的宽     this.setWIDth(WindowManager.LayoutParams.FILL_PARENT);     //设置SelectPicPopupWindowd出窗体的高     this.setHeight(WindowManager.LayoutParams.WRAP_CONTENT);     //设置SelectPicPopupWindowd出窗体可点击     this.setFocusable(true);     //设置PopupWindow可触摸     this.settouchable(true);     //设置非PopupWindow区域是否可触摸 //    this.setoutsIDetouchable(false);     //设置SelectPicPopupWindowd出窗体动画效果 //    this.setAnimationStyle(R.style.select_anim);     //实例化一个colorDrawable颜色为半透明     colorDrawable DW = new colorDrawable(0x00000000);     //设置SelectPicPopupWindowd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);       }     });   }    //为d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;       }     }    }; }
