public class ShowPopUtils {

     privateView contentView;
      private PopupWindow popupWindow;

      public void showPop(Context mc, View m) { 
      LayoutInflater inflater = LayoutInflater.from(mc); 
      contentView = inflater.inflate(R.layout.popup_shop_service, null); 
      popupWindow = new PopupWindow(contentView);
     contentView.findViewById(R.id.tv_pss_cancel).setOnClickListener(new View.OnClickListener() { 
           @Override 
            public void onClick(View view) {
            popupWindow.dismiss(); 
           } 
      }); 
     //背景色 不设置背景不能点击外面消失 
     popupWindow.setBackgroundDrawable(new ColorDrawable(Color.argb(50, 52, 53, 55))); 
    //宽高 
     popupWindow.setHeight(LinearLayout.LayoutParams.MATCH_PARENT); 
     popupWindow.setWidth(LinearLayout.LayoutParams.MATCH_PARENT);
    //设置点击窗口外边窗口消失 
     popupWindow.setOutsideTouchable(true); 
     // 设置此参数获得焦点，否则无法点击
    popupWindow.setFocusable(true);
    //显示位置 activity底部弹出 
     popupWindow.showAtLocation(mView, Gravity.BOTTOM, 0, 0); }

      public View getV() {
       returncontentView;
     }

      public void dismiss() {
         if (popupWindow != null && popupWindow.isShowing()) {
            popupWindow.dismiss();
         }
      }

}

布局文件

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:background="@android:color/transparent"
    android:orientation="vertical">

    <TextView
        android:id="@+id/tv_pss_bg"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_weight="1" />

    <TextView
        android:id="@+id/tv_pss_title"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:background="@color/colorText"
        android:gravity="center"
        android:paddingTop="@dimen/car_10px"
        android:text="提示"
        android:textColor="@color/color_setup_text" />

    <ListView
        android:id="@+id/lv_pss_service"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:background="@color/colorText" />

    <TextView
        android:id="@+id/tv_pss_cancel"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_marginBottom="@dimen/car_8px"
        android:layout_marginTop="@dimen/car_5px"
        android:background="@color/colorText"
        android:gravity="center"
        android:padding="@dimen/car_20px"
        android:text="取消" />
</LinearLayout>

调用方法

 private void showService(final List<DataBean> mList) {
        final ShowPopUtils showPopUtils = new ShowPopUtils();
        //方法调用  传上下文和view
        showPopUtils.showPop(mContext, findViewById(R.id.tv_asi_rz));
        //得到布局
        View contentView = showPopUtils.getV();
        ListView mLv_service = (ListView) contentView.findViewById(R.id.lv_pss_service);      
        ServiceListAdapter serviceListAdapter = new ServiceListAdapter(mContext, mList);

        mLv_service.setAdapter(serviceListAdapter); 
        mLv_service.setOnItemClickListener(new AdapterView.OnItemClickListener() { 
           @Override 
           public void onItemClick(AdapterView<?> adapterView, View view, int i, long l) { 
                showPopUtils.dismiss();//销毁
           } 
        }); 
 }

位置

     
    1、popupWindow.showAsDropDown(mView);//在控件的正下方
    
    2、popupWindow.showAtLocation(mView, Gravity.BOTTOM, 0, 0);//activity底部弹出
     
       int[] location = new int[2];
       mLine.getLocationOnScreen(location);

    3、popupWindow.showAtLocation(mView, Gravity.NO_GRAVITY, location[0], location[1] - popupWindow.getHeight());//控件的正上方  
      
    4、//控件的左边

       popupWindow.showAtLocation(v13, Gravity.NO_GRAVITY, location[0] - popupWindow.getWidth()
                               , location[1] - (popupWindow.getHeight() - v13.getHeight()) / 2);
