按名称查找视图 [英] Find view by name

问题描述

是否可以通过名称而不是 id 来查找视图.

Is it possible to find a view by its name rather than its id.

findViewById(R.id.someView);

但我想做这样的事情:

findViewByName("someView");

推荐答案

在处理xml的时候必须通过标识符来查找视图，但是可以使用getIdentifier(String name, ...) 例如，如果您对布局进行编号，这将很有用.请注意，这样的查找成本相对较高.

you have to find views by identifier when dealing with xml, but you can look up the identifier by using getIdentifier(String name, ...) which is useful if you have your layouts numbered for example. Just be aware that such a lookup is relatively expensive.

完成答案

int id = getResources().getIdentifier(name, "id", context.getPackageName());
View view = findViewById(id);
