java - Android Java 将 OnClick 设置为多个嵌套标签中的 ImageView

Question

大家好，我正在尝试创建一个在单击个人资料图片时会出现的菜单：

但正如您所见，ImageView 位于 cardView 内，而 cardView 又位于工具栏内，作为初始父级，我有一个 App Bar 布局：

</androidx.constraintlayout.widget.ConstraintLayout>

我尝试从 java 代码中设置 OnClick 侦听器，但是当我运行应用程序时，单击图像时 onclick 不起作用：

 ImageView img_profilo = findViewById(R.id.img_profilomain);

        img_profilo.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                Toast.makeText(MainActivity.this, "d", Toast.LENGTH_SHORT).show();
                mnuItem.setVisibility(View.VISIBLE);
            }
        });

我也尝试使用工具栏来执行此操作，但无论如何它都不起作用：

tlb.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                Toast.makeText(MainActivity.this, "sad", Toast.LENGTH_SHORT).show();
            }
        });

编辑：它也不适用于这个

Toolbar toolbar = findViewById(R.id.toolbar);

        toolbar.setOnMenuItemClickListener(new Toolbar.OnMenuItemClickListener() {
            @Override
            public boolean onMenuItemClick(MenuItem item) {

                if(item.getItemId() == R.id.img_profilomain)
                    Toast.makeText(MainActivity.this, "wds", Toast.LENGTH_SHORT).show();
                return true;
            }
        });

有人知道如何解决这个问题吗？
