Question

Fragment中的按钮无法点击是怎么回事

Answer 1

代码是错误的，既然是fragment中的按钮那就并不是在activity中设置按钮监听getActivity()只是用来获取到一个Context上下文的，因为startActivity是context的方法，而Activity又继承于Context正确代码如下fragmentclass MyFragment extends Fragment{@Overridepublic View onCreateView(LayoutInflater inflater, ViewGroup container,Bundle savedInstanceState) {View view = inflater.inflate(R.layout.frag_pre, mull);//在fragment视图中的按钮Button btn = (Button)view.findViewById(R.id.button);btn.setOnClickListener(new OnClickListener() {@Overridepublic void onClick(View v) { //在这里使用getActivityIntent intent = new Intent(getActivity(),Pre1Activity.class);startActivity(intent);}});return super.onCreateView(inflater, container, savedInstanceState);}}
