Question

我在ToolBar上有购物车图标。当我尝试点击时，它很长时间没有显示任何动作。继续点击它，我设置的Toast消息已启用或应用程序崩溃。

请帮我解决。

我的代码是：

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        getMenuInflater().inflate(R.menu.main, menu);
        badgeLayout = (RelativeLayout) menu.findItem(R.id.badge).getActionView();
        mCounter = (TextView) badgeLayout.findViewById(R.id.counter);
        badgeLayout.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                Toast.makeText(context, "Cart is Working", Toast.LENGTH_SHORT).show();
                Intent next = new Intent(context, ProductActivity.class);
                startActivity(next);
            }
        });
return true;
}

Answer 1

问题可能已经结束，但我找到了可能的原因：

如果您在.xml文件中使用了相对布局，则相邻元素可以覆盖您的工具栏。因此，您的工具栏必须位于.xml文件中的顶视图中。它对我有用。

Answer 2

您应该使用OnOptionsItemSelected()

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    // Handle item selection
    switch (item.getItemId()) {
        case R.id.badge:
            Toast.makeText(context, "Cart is Working", Toast.LENGTH_SHORT).show();
            Intent next = new Intent(context, ProductActivity.class);
            startActivity(next);
            return true;
        default:
            return super.onOptionsItemSelected(item);
    }
}

Answer 3

问题是您在点击super.onOptionsItemSelected(item)时没有致电badge。按如下方式更改方法： -

@Override
public boolean onOptionsItemSelected(MenuItem item) {
       super.onOptionsItemSelected(item)
       switch (item.getItemId()) {
            case R.id.action_search:
                 break;
            case R.id.badge:
                 Toast.makeText(context, "Cart is Working", Toast.LENGTH_SHORT).show();
            /* Intent next = new Intent(context, ProductActivity.class);
                   startActivity(next);*/
                   break;
             default:
                   break;
            }
            return true;
     }
