如何获取动态添加到LinearLayout的点击子视图的ID？

Question

我正在向线性布局添加子视图。子视图本身在相对布局中有一些文本视图和图像视图。 单击按钮时，子视图会动态添加到 LinearLayout 中。现在我可以添加子视图，如图所示。 http://dl.dropbox.com/u/50249620/SC20120926-031356.png 我必须做的是唯一地确定单击了哪个子视图以显示适当的操作。 我在其中添加子视图的代码。

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);              

            }
        }); 

任何帮助或建议将不胜感激。谢谢。

您可以在创建视图时简单地通过执行以下操作向任何视图添加自定义标签

view.setTag(Object o);

然后稍后在 onClickListener 中找到带有

的标签

view.getTag()

setTag(Object o) 将接受任何类型的对象，无论是字符串、int 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
        }
    }
