1、先申明一个监听对象
2、不同按钮设置同一个监听对象
3、监听中，通过按钮的id判断是哪个按钮的点击事件
代码如下
1、new监听
OnClickListener clickListener = new OnClickListener(){
@Override
public void onClick(View v) {
if (v.getId()==R.id.button1){//按钮1
}else if(v.getId()==R.id.button2}{//按钮2
}
}
2、设置监听
Button btn1 = (Button)findViewById(R.id.button1);
Button btn2 = (Button)findViewById(R.id.button1);
btn1.setOnClickListener(clickListener);
btn2.setOnClickListener(clickListener);
public static class PlaceholderFragment extends Fragment implements
OnClickListener {
public PlaceholderFragment() {
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.fragment_main, container,
false);
button1 = (Button) rootView.findViewById(R.id.button1);
button2 = (Button) rootView.findViewById(R.id.button2);
button3 = (Button) rootView.findViewById(R.id.button3);
button4 = (Button) rootView.findViewById(R.id.button4);
button1.setOnClickListener(this);
button2.setOnClickListener(this);
button3.setOnClickListener(this);
button4.setOnClickListener(this);
return rootView;
}
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
switch (v.getId()) {
case R.id.button1:
Toast.makeText(getActivity(), "这是BUTTON1", Toast.LENGTH_SHORT).show();
break;
case R.id.button2:
Toast.makeText(getActivity(), "这是BUTTON2", Toast.LENGTH_SHORT).show();
break;
case R.id.button3:
Toast.makeText(getActivity(), "这是BUTTON3", Toast.LENGTH_SHORT).show();
break;
case R.id.button4:
Toast.makeText(getActivity(), "这是BUTTON4", Toast.LENGTH_SHORT).show();
break;
default:
break;
}
}
}
