viewpage 使用addview出错

Question

我使用viewpage 完成界面的切换

    mviewPager = (ViewPager) findViewById(R.id.id_viewpager);

        mtabhome = (LinearLayout) findViewById(R.id.id_tabhome);
        mtabrelease = (LinearLayout) findViewById(R.id.id_tabrelease);
        mtabpersonal = (LinearLayout) findViewById(R.id.id_tabpersonal);
        // imgbtn1
        releaseimgbtn = (ImageButton) findViewById(R.id.id_releaseimgbtn);
        homeimgbtn = (ImageButton) findViewById(R.id.id_homeimgbtn);
        personalimgbtn = (ImageButton) findViewById(R.id.id_personalimgbtn);

        LayoutInflater minflater = LayoutInflater.from(this);

        View tabhome = minflater.inflate(R.layout.homelayout, null);
        View tabrelease = minflater.inflate(R.layout.releaselayout, null);
        View tabpersonal = minflater.inflate(R.layout.personallayout, null);

        mviews.add(tabhome);
        mviews.add(tabrelease);
        mviews.add(tabpersonal);

        **mviewPager.addView(tabhome);
        mviewPager.addView(tabpersonal);
        mviewPager.addView(tabrelease);**

        mpageradapter = new PagerAdapter()

        {

            @Override
            public void destroyItem(ViewGroup container, int position,
                    Object object) {
                View view = mviews.get(position);
                container.removeView(view);

            }

            @Override
            public Object instantiateItem(ViewGroup container, int position) {
                View view = mviews.get(position);
                container.addView(view);
                return view;
            }

            @Override
            public boolean isViewFromObject(View view, Object arg1) {

                return view == arg1;
            }

            @Override
            public int getCount() {
                return mviews.size();
            }
        };
        mviewPager.setAdapter(mpageradapter);

这三行代码不写上程序就出错，而且只能写第一行和第三行
mviewPager.addView(tabhome);
//mviewPager.addView(tabpersonal);
mviewPager.addView(tabrelease);**

Answer 1

你添加的view的数量要和mviews.size()一致
