Android中fragment实现按钮点击事件

fragment无法直接进行点击事件，需要放到oncreatActivity中

方法如下：

public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
return inflater.inflate(R.layout.main_tab1_fragment, container, false);
}

@Override
public void onActivityCreated(Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
Button button = (Button) getActivity().findViewById(R.id.testbt);
button.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
Toast.makeText(getActivity(), "nihao", Toast.LENGTH_LONG).show();

}
});
}
