导航栏：用RadioButton

标题：动态添加

主内内容区：ViewPager

自定义ViewPageri重写父类的onTouchEvent()方法。

import android.content.Context;
import android.support.v4.view.ViewPager;
import android.util.AttributeSet;
import android.view.MotionEvent;

public class NoScrollViewPager extends ViewPager {

public NoScrollViewPager(Context context) {
super(context);
}

public NoScrollViewPager(Context context, AttributeSet attrs) {
super(context, attrs);
}

@Override
public boolean onTouchEvent(MotionEvent arg0) {//禁止ViewPager的触摸事件
return false;
}

}

java代码：
