处理弹出菜单项单击

Question

我已经为我的 android 应用程序实现了一个弹出菜单。我为弹出菜单创建了一个 xml，代码也可以正常工作。现在我想不通的是如何处理弹出菜单项的点击。我试过使用 PopupMenu.OnMenuItemClickListener 但没有成功。我该怎么做？

我的弹出菜单代码

ImageButton button = (ImageButton) view.findViewById(R.id.popUp_song);

            button.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {


                    PopupMenu popup = new PopupMenu(activity, v);
                    Menu m = popup.getMenu();
                    MenuInflater inflater = popup.getMenuInflater();
                    inflater.inflate(R.menu.song_popup, popup.getMenu());

                    if (audio.getDownload().equals("0")) {

                        m.removeItem(R.id.add_download);

                    }

                    popup.show();
                }


            });

xml

<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android"
    style="@style/ToolBarStyle">

    <item
        android:id="@+id/add_queue"
        android:title="Add to queue" />
    <item
        android:id="@+id/play_next"
        android:title="Add to favourite" />
    <item
        android:id="@+id/add_download"
        android:title="Download" />


</menu>

Answer 1

在显示 PopupMenu 之前，为 PopupMenu 添加一个监听器来处理点击事件。

popupMenu.setOnMenuItemClickListener(new OnMenuItemClickListener() {

                    @Override
                    public boolean onMenuItemClick(MenuItem item) {
                        Toast.makeText(getApplicationContext(),
                                item.getTitle(), Toast.LENGTH_SHORT).show();
                        return true;
                    }
                });

如果需要根据id点击弹出菜单，正确的做法如下：

 popup.setOnMenuItemClickListener(item -> {
           if (item.getItemId() == R.id.miEmail) {
                Toast.makeText(getApplicationContext(), "Email clicked", Toast.LENGTH_SHORT).show();
            } else if (item.getItemId() == R.id.miCall) {
                Toast.makeText(getApplicationContext(), "Call clicked", Toast.LENGTH_SHORT).show();
            }

            return true;
        });
