推荐答案
您只需要一点创意！
就在做这样的事情：
子类的View.OnClickListener
Subclass the View.OnClickListener
abstract class ProxyAbleClickListener implements OnClickListener {
Runnable ProxyAction;
@Override
public void onClick(View arg0) {
if (ProxyAction != null) {
ProxyAction.run();
}
}
public void setProxyAction(Runnable proxyAction) {
ProxyAction = proxyAction;
}
}
/* Somwhere in your code ! */
YourView view = new Button(context);
view.setOnClickListener(new ProxyAbleClickListener() {
public void onClick(View arg0) {
// Insert onClick Code here
super.onClick(arg0);
}
});
ProxyAbleClickListener listener = (ProxyAbleClickListener) view.getOnClickListener();
listener.setProxyAction(new Runnable() {
@Override
public void run() {
// Insert your proxy code here..
}
});
请确保有一个子类图片喜欢YourView它覆盖setOnClickListener并有一个参考，听者与getOnClickListner ..
Make sure to have a subclassed view Like YourView that overrides the setOnClickListener and keeps a reference to the listener to access with getOnClickListner..
我没有测试此code以任何方式，把它当作伪$ C $下你需要做的。
I have not tested this code in any way, treat it as pseudo code for what you need to do.
