从片段呼叫活动的按钮clickListener？ [英] Call Button clickListener of activity from fragment?

问题描述

我有我的活动包含片段里面的按钮。从片段之一，我需要调用按钮，按钮clickListener并传递一个意图与群众演员到另一个活动。我怎样才能做到这一点？我搜索了很多本，但无法找到这个合适的解决方案。

I have a button inside my activity which contain fragments. From one of the fragment I need to call button, button clickListener and pass an intent with extras to another activity. How can I do this? I searched a lot for this but couldn't find an appropriate solution for this.

推荐答案

实施onClickListener在活动按钮：

Implement the onClickListener for the button in the activity:

button.setOnClickListener(new View.OnClickListener() {

@Override
public void onClick(View v) {
    // get the fragment from the fragment manager
    Fragment frag = getFragmentManager().findFragmentByTag("FRAGMENT TAG");
    Bundle extras = frag.getExtrasForNewActivity();

    /// Your code here this is for Activity
    Intent intent=new Intent(getActivity(),Second.class);
    intent.putExtras(extras);
    startActivity(intent);
 }
});

和片段中，创建一个方法，像这样：

and in the fragment, create a method like so:

public Bundle getExtrasForNewActivity()
{
    /// return a bundle with values
}
