android 开发：fragment 和 activity通信

dileber android 框架：乁( ˙Ω˙ )厂 跳转链接 dileber android框架 怎么说呢？既然看到了就在github上star一下呗 (´ཀ`」 ∠)

fragment中设置监听器 dileber框架中的BaseFragment有一个监听器如下

protected OnBaseInteractionListener mBaseListener; public interface OnBaseInteractionListener { void onRightButtonString(String str, View.OnClickListener onClickListener); void onTitleName(String title); } protected void setActivityRightButton(String str,View.OnClickListener onClickListener) { if (mBaseListener != null) { mBaseListener.onRightButtonString(str,onClickListener); } } protected void setActivityTitle(String title){ if (mBaseListener != null) { mBaseListener.onTitleName(title); } } @Override public void onDetach() { super.onDetach(); mBaseListener = null; }

该监听器的作用是 设置activity的title bar菜单按钮文字，和点击效果。 设置activity title

让activity 实现OnBaseInteractionListener接口 并在fragment中设置

@Override public void onAttach(Context context) { super.onAttach(context); if (context instanceof OnBaseInteractionListener) { mBaseListener = (OnBaseInteractionListener) context; } else { throw new RuntimeException(context.toString() + " must implement OnBaseInteractionListener"); } }

在fragment 中调用

setActivityRightButton("创建", new View.OnClickListener() { @Override public void onClick(View v) { mPresenter.createSaleChance(s_theme.getText().toString(),myaccount,s_product,d,stage_goal ,possibility_of_success,priority,remark.getText().toString()); } });

如图效果
