由于前段时间都在赶app的进度,没时间更新博客文章了 ,现在有时间就写写PopupWindow自定义,可以根据自定义的布局完成你想要的效果,废话我就不多说了直接上代码,一个自定义PopupWindow的工具类可直接拷贝用到自己的项目中.

public class PopuUtils {
    public static PopupWindow popupWindow;
    public static View sPopLayout;
    private static Activity mActivity;
    /**
     * 封装的这个popupwindow的工具类
     * @param v   显示在哪个控件下面
     * @param y    显示的y轴的位置
     * @param convertViewResource  填充到popupWindow中的布局文件id
     * @param activity    依附的activity
     * @param gravity     在布局的位置
     */
    public static void showPopWindow(View v, int y, int convertViewResource, final Activity activity,int gravity) {
        //创建一个popUpWindow,当其他界面使用该popu的时候只需判断所传的activity是否相等,不等就重新创建对象
        if (popupWindow == null || mActivity != activity) {
            sPopLayout = LayoutInflater.from(activity).inflate(convertViewResource, null);
            //实例化一个popupWindow
            popupWindow = new PopupWindow(sPopLayout, LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.WRAP_CONTENT, true);
            //产生背景变暗效果
            WindowManager.LayoutParams lp = activity.getWindow().getAttributes();
            lp.alpha = 0.4f;
            activity.getWindow().setAttributes(lp);
            //点击外面popupWindow消失
            popupWindow.setOutsideTouchable(true);
            //popupWindow获取焦点
            popupWindow.setFocusable(true);
            popupWindow.setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));
        } else {
            //如果popupWindow正在显示，接下来隐藏
            if (popupWindow.isShowing()) {
                popupWindow.dismiss();
            } else {
                //产生背景变暗效果
                WindowManager.LayoutParams lp = activity.getWindow().getAttributes();
                lp.alpha = 0.4f;
                activity.getWindow().setAttributes(lp);
            }
        }
        //记录所传的activity对象
        mActivity = activity;
        //设置popupWindow消失时的监听
        popupWindow.setOnDismissListener(()-> {
            //在dismiss中恢复透明度
            WindowManager.LayoutParams lp = activity.getWindow().getAttributes();
            lp.alpha = 1f;
            activity.getWindow().setAttributes(lp);
        });
        popupWindow.setSoftInputMode(PopupWindow.INPUT_METHOD_NEEDED);
        popupWindow.setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_ADJUST_RESIZE);
        popupWindow.showAtLocation(v,gravity , 0, y);
    }

    /**
     * 返回popupWindow的view
     * @return
     */
    public static View getPopLayout() {
        return sPopLayout;
    }

    /**
     * 返回popupWindow对象
     * @return
     */
    public static PopupWindow getPopupWindow() {
        return popupWindow;
    }
