查找视图的名字 [英] Find view by name
问题描述
是否有可能找到一个鉴于它的名字,而不是它的id。
findViewById(R.id.someView);
但我希望做这样的事情:
findViewByName(someView);
您在处理XML处理发现的观点被识别,但你可以看一下标识使用<一个href="http://developer.android.com/reference/android/content/res/Resources.html#getIdentifier%28java.lang.String,%20java.lang.String,%20java.lang.String%29">getIdentifier(String名,...)如果你有你的布局编号,例如这是有用的。要知道,这样的查询是比较昂贵的。
完成答案
内部ID = getResources()则getIdentifier(姓名,ID,context.getPackageName())。
查看查看= findViewById(ID);
Is it possible to find a view by its name rather than its id.
findViewById(R.id.someView);
but I would like to do something like this:
findViewByName("someView");
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.
to complete the answer
int id = getResources().getIdentifier(name, "id", context.getPackageName());
View view = findViewById(id);
