Question

我在列表视图中使用自定义弹出窗口，此弹出窗口需要在触发器视图的高度和触发器视图的左侧中间绘制。

我能够实现第一部分，第二部分似乎难以捉摸，这是我的代码：

public class QuickAction implements View.OnTouchListener {

    private View triggerView;
    private PopupWindow window;
    protected final WindowManager windowManager;

    public QuickAction(View triggerView) {
        this.triggerView = triggerView;
        window = new PopupWindow(triggerView.getContext());
        window.setTouchable(true);
        window.setTouchInterceptor(this);
        windowManager = (WindowManager) triggerView.getContext().getSystemService(Context.WINDOW_SERVICE);
        ImageView imageView = new ImageView(triggerView.getContext());
        imageView.setImageResource(R.drawable.ic_action_email);


        LayoutInflater layoutInflater = (LayoutInflater) triggerView.getContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        View layout = layoutInflater.inflate(R.layout.quick_action_popup_layout, null, false);


        window.setContentView(layout);
        //  window.setBackgroundDrawable(null);
        window.setWidth(WindowManager.LayoutParams.WRAP_CONTENT);
        window.setHeight(WindowManager.LayoutParams.WRAP_CONTENT);
        window.setTouchable(true);
        window.setFocusable(false);
        window.setOutsideTouchable(true);
    }

    public boolean onTouch(View v, MotionEvent event) {
        if (MotionEvent.ACTION_OUTSIDE == event.getAction()) {
            this.window.dismiss();
            return true;
        }
        return false;
    }

    public void show() {
        int[] location = new int[2];
        triggerView.getLocationOnScreen(location);
        window.showAtLocation(triggerView, Gravity.NO_GRAVITY, location[0] + (triggerView.getLeft()), location[1] + (triggerView.getHeight() / 2));
    }

}

我想要的是将弹出窗口的右边缘与我的triggerview的左侧边缘对齐

Triggerview是我想要生成弹出窗口的按钮，代码的相关部分是：

 public void show() {
        int[] location = new int[2];
        triggerView.getLocationOnScreen(location);
        window.showAtLocation(triggerView, Gravity.NO_GRAVITY, location[0] + (triggerView.getLeft()), location[1] + (triggerView.getHeight() / 2));
    }

然而，这并没有给我预期的结果。有任何想法吗？

Answer 1

指定$categories = new \TYPO3\CMS\Extbase\Persistence\ObjectStorage; $category1 = new \VENDX\Items\Domain\Model\Category; //1st catobj $category1->setCatName('Cat1'); //First category $categories->attach($category1); $category2 = new \VENDX\Items\Domain\Model\Category; //2nd catobj $category2->setCatName('Cat2'); //Second category $categories->attach($category2); $item->setCategories($categories);的重力与指定类似 NO_GRAVITY。

如果您想将弹出窗口的右侧放置在指定位置，则需要Gravity.LEFT | Gravity.TOP而不是Gravity.TOP | Gravity.RIGHT。

在视图的左边缘显示弹出窗口
