我正在使用View寻呼机在Android中滑动页面,我的所有页面都有按钮,我想设置按钮上的点击监听器。我怎样才能做到这一点?我查了这个链接。 On Click listener is not working in View Pager但它对我不起作用。
这是我的代码:
Main.class
public class MainActivity extends Activity {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
MyPagerAdapter adapter = new MyPagerAdapter();
ViewPager myPager = (ViewPager) findViewById(R.id.myfivepanelpager);
myPager.setAdapter(adapter);
myPager.setCurrentItem(2);
Button btnDone = (Button) findViewById(R.id.buttonalpha);
btnDone.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View arg0) {
// TODO Auto-generated method stub
Toast.makeText(getApplicationContext(), "clicked", Toast.LENGTH_SHORT).show();
}
});
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
}
ViewPager
public class MyPagerAdapter extends PagerAdapter {
public int getCount() {
return 3;
}
public Object instantiateItem(View collection, int position) {
LayoutInflater inflater = (LayoutInflater) collection.getContext()
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
int resId = 0;
switch (position) {
case 0:
resId = R.layout.hello;
break;
case 1:
resId = R.layout.hello2;
break;
case 2:
resId = R.layout.hello3;
break;
/*case 3:
resId = R.layout.right;
break;
case 4:
resId = R.layout.farright;
break;*/
}
View view = inflater.inflate(resId, null);
((ViewPager) collection).addView(view, 0);
return view;
}
@Override
public void destroyItem(View arg0, int arg1, Object arg2) {
((ViewPager) arg0).removeView((View) arg2);
}
@Override
public boolean isViewFromObject(View arg0, Object arg1) {
return arg0 == ((View) arg1);
}
@Override
public Parcelable saveState() {
return null;
}
}
任何帮助将不胜感激。

我认为最好使用FragmentPagerAdapter。
片段的例子。
public class YourFragment extends Fragment {
private OnClickListener mListener;
public static YourFragment newInstance(int layoutId){
Bundle args = new Bundle();
args.putInt("id", layoutId);
YourFragment fr = new YourFragment();
fr.setArguments(args);
return fr;
}
@Override
public void onAttach(Activity activity) {
super.onAttach(activity);
mListener = (OnClickListener)activity;
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View view = inflater.inflate(getArguments().getInt("id"), container, false);
view.findViewById(R.id.action_bar).setOnClickListener(mListener);
return view;
}
}
mainActivity应该是imlement OnClickListener。
