java - 如何将弹出菜单添加到一个 Activity 中的多个按钮？

Question

我在向不同按钮添加多个弹出菜单时遇到问题。但是，我配置为向一个设置按钮添加一个弹出菜单，如下面的屏幕截图所示，但当我将相同的代码应用于其他设置按钮时，应用程序崩溃了。

请告诉我如何为所有不同的设置按钮添加多个弹出菜单。

Answer 1

定义一个监听器:

View.OnClickListener listener = new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        // place your code here
        switch (v.getId()) {
            case R.id.btn_play1:
                PopupMenu popupMenu = new PopupMenu(ringtone_tab.this, v);
                popupMenu.getMenuInflater().inflate(R.menu.popup_menu, popupMenu.getMenu());
                popupMenu.setOnMenuItemClickListener(new PopupMenu.OnMenuItemClickListener() {
                    @Override
                    public boolean onMenuItemClick(MenuItem item) {
                        Toast.makeText(ringtone_tab.this, "" + item.getTitle(), Toast.LENGTH_SHORT).show();
                        return true;
                    }
                });
                popupMenu.show();
                break;
            case R.id.btn_play2:
                // place your code here
                break;
        }
    }
};

并将此监听器应用于所有按钮:

clk1.setOnClickListener(listener);
clk2.setOnClickListener(listener);
