Android. Find view by tag
提问by BenG
I have a dynamically created View and want to find it by tag, is this possible?
I know the function findViewById, is there something similar for tags?
我有一个动态创建的视图，想通过标签找到它，这可能吗？我知道这个功能findViewById，标签有类似的东西吗？

LinearLayout linLayout = (LinearLayout)findViewWithTag("layout1");
but I don't think you need tag for dynamic view. You can retrieve dynamic resource by following code
但我认为您不需要标记动态视图。您可以通过以下代码检索动态资源
for (int i=0; i < total_resource; i++) {
//retrieve id dynamically
int id = getResources().getIdentifier("resource"+i, "id", getPackageName());
TextView myText = (TextView) findViewById(id); // get the element
}

Create ids.xml to store your id:
创建 ids.xml 来存储您的 id：
<?xml version="1.0" encoding="utf-8"?> <resources> <item type="id" name="component1" /> <item type="id" name="component2" /> <item type="id" name="component3" /> </resources>
Set to dynamically created component like:
设置为动态创建的组件，如：
Button1.setId(R.id.layout1); buttom2.setId(R.id.layout2); button3.setId(R.id.layout3);
Another way is to set a tag to your component while creating dynamically
另一种方法是在动态创建组件时为组件设置标签
button1.setTag(1);
And use getTag()to get that component
并用于getTag()获取该组件
