Fragment接口回调(左右分屏显示)

左侧的Fragment给右侧的传值

左边Fragment自定义接口

// 设置点击事件

listview.setOnItemClickListener(new OnItemClickListener() {


@Override
public void onItemClick(AdapterView parent, View view,
int position, long id) {
String string = list.get(position);

listener.OnZidingyiClick(string);
}
});
}


private ZidingyiListener listener;


public void setZidingyiListener(ZidingyiListener listener) {
this.listener = listener;
}


interface ZidingyiListener {
void OnZidingyiClick(String str);

}

右边的Fragment

@Override
public void onActivityCreated(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onActivityCreated(savedInstanceState);
textview = (TextView) view.findViewById(R.id.textview);
// 得到Fragment_Left对象
Fragment_Left left=(Fragment_Left) getActivity().getSupportFragmentManager().findFragmentById(R.id.left);
// 调用自定义的接口
left.setZidingyiListener(new ZidingyiListener() {

@Override
public void OnZidingyiClick(String str) {
textview.setText(str);

}
});
}
