android - 如何获取动态添加到 LinearLayout 中的点击 subview 的 ID？

Question

我正在向线性布局添加 subview 。 subview 本身在 Relativelayout 中有一些 TextView 和 ImageView 。 单击按钮时， subview 会动态添加到 LinearLayout 中。现在我可以添加 subview ，如图所示。 http://dl.dropbox.com/u/50249620/SC20120926-031356.png 我必须做的是唯一地标识已单击哪个 subview 以显示适当的操作。 我添加 subview 的代码。

addButton.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                // TODO Auto-generated method stub
                inflater = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE);


                customView1 = inflater.inflate(R.layout.people, null);

                peopleName = (TextView) customView1.findViewById(R.id.peopleName);

                peopleName.setText(autoComplete.getText());
                customView1.setId(peopleInvitedRelativeLayout.getChildCount() + 1);

                params4 = new LinearLayout.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT);

                customView1.setLayoutParams(params4);
                peopleInvitedRelativeLayout.addView(customView1, params4);              

            }
        }); 

如有任何帮助或建议，我们将不胜感激。谢谢。

您可以在创建 View 时简单地通过执行以下操作将自定义标签添加到任何 View

view.setTag(Object o);

然后在 onClickListener 中找到标签

view.getTag()

setTag(Object o) 将接受任何类型的对象，无论是字符串、整数还是自定义类

编辑

addButton.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            // TODO Auto-generated method stub
            inflater = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE);


            customView1 = inflater.inflate(R.layout.people, null);

            peopleName = (TextView) customView1.findViewById(R.id.peopleName);

            peopleName.setText(autoComplete.getText());
            customView1.setId(peopleInvitedRelativeLayout.getChildCount() + 1);

            params4 = new LinearLayout.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT);

            customView1.setLayoutParams(params4);
            peopleInvitedRelativeLayout.addView(customView1, params4);

            //add a tag to a view and add a clicklistener to the view
            customView1.setTag(someTag);
            customView1.setOnClickListener(myClickListner);



        }
    });

clicklistener - 为它创建一个类变量

OnClickListener myClickListener = new onClickListener(){
    @Override
    public void onClick(View v) {

        if(v.getTag() == someTag){
             //do stuff
        }else if(v.getTag() == otherTag){
             //do something else
        }
    }
