android - Android:WindowManager:android.view.WindowLeaked: Activity

我正在尝试使用一些按钮实现弹出窗口。我在单击按钮时打开弹出窗口时遇到E / WindowManager：android.view.WindowLeaked：活动的错误。这是我的活动代码。此行的错误= pwindo.showAtLocation（layout，Gravity.BOTTOM，0，0）;

private void initiatePopupWindow()
    {
        try
        {
            LayoutInflater inflater = (LayoutInflater) AddPost.this.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
            View layout = inflater.inflate(R.layout.camera_popup, (ViewGroup) findViewById(R.id.popup_element));
            pwindo = new PopupWindow(layout, 700, 380, true);
            pwindo.showAtLocation(layout, Gravity.BOTTOM, 0, 0);
            pwindo.setBackgroundDrawable(new ColorDrawable(android.graphics.Color.TRANSPARENT));

            btnCamera = (Button) layout.findViewById(R.id.button_Camera);
            btnCamera.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {
                    Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
                    startActivityForResult(cameraIntent, CAMERA_REQUEST);
                }
            });

            btnGallery = (Button) layout.findViewById(R.id.button_Gallery);
            btnGallery.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {

                    Intent galleryIntent = new Intent(Intent.ACTION_PICK, android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
                    startActivityForResult(galleryIntent, RESULT_LOAD_IMG);

                   }
            });

            cancelPopUp = (Button) layout.findViewById(R.id.btnCancelCamera);
            cancelPopUp.setOnClickListener(cancel_button_click_listener);

        } catch (Exception e) {
            e.printStackTrace();
        }
    }

这是我的日志猫错误

放
pwindo.dismiss()在Onclick事件中。
