可实现功能效果说明：

　　可实现多张图片点击放大，手指控制，左右滑动，多张图片点击任意位置定位显示任意位置图片；无动画，可自己加

效果图：

核心代码：

viewpager:

public class PhotoViewPager extends ViewPager {

    public PhotoViewPager(Context context) {

        super(context);

    }

    public PhotoViewPager(Context context, AttributeSet attrs) {

        super(context, attrs);

    }

    @Override

    public boolean onInterceptTouchEvent(MotionEvent ev) {

        try {

            return super.onInterceptTouchEvent(ev);

        } catch (IllegalArgumentException e) {

            e.printStackTrace();

            return false;

        }

    }

}

adapter:

public class MyImageAdapter extends PagerAdapter {

    public static final String TAG = MyImageAdapter.class.getSimpleName();

    private List<String> imageUrls;

    private AppCompatActivity activity;

    public MyImageAdapter(List<String> imageUrls, AppCompatActivity activity) {

        this.imageUrls = imageUrls;

        this.activity = activity;

    }

    @Override

    public Object instantiateItem(ViewGroup container, int position) {

        String url = imageUrls.get(position);

        PhotoView photoView = new PhotoView(activity);

        Picasso.with(activity)

                .load(url)

                .into(photoView);

        container.addView(photoView);

        photoView.setOnClickListener(new View.OnClickListener() {

            @Override

            public void onClick(View view) {

                Log.d(TAG, "onClick: ");

                activity.finish();

            }

        });

        return photoView;

    }

    @Override

    public int getCount() {

        return imageUrls != null ? imageUrls.size() : 0;

    }

    @Override

    public boolean isViewFromObject(View view, Object object) {

        return view == object;

    }

    @Override

    public void destroyItem(ViewGroup container, int position, Object object) {

        container.removeView((View) object);

    }

    @Override

    public int getItemPosition(Object object) {

        return POSITION_NONE;

    }

}

photoViewActivity

public class PhotoViewActivity extends AppCompatActivity implements View.OnClickListener {

    public static final String TAG = PhotoViewActivity.class.getSimpleName();

    private PhotoViewPager mViewPager;

    private int currentPosition;

    private MyImageAdapter adapter;

    private TextView mTvImageCount;

    private TextView mTvSaveImage;

    private List<String> Urls;

    @Override

    protected void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);

        setContentView(R.layout.activity_photo_view);

        initView();

        initData();

    }

    private void initView() {

        mViewPager = (PhotoViewPager) findViewById(R.id.view_pager_photo);

        mTvImageCount = (TextView) findViewById(R.id.tv_image_count);

        mTvSaveImage = (TextView) findViewById(R.id.tv_save_image_photo);

        mTvSaveImage.setOnClickListener(this);

    }

    private void initData() {

        Intent intent = getIntent();

        currentPosition = intent.getIntExtra("currentPosition", 0);

        HomeQuestionListModel.DataBeanX DataBean = ((HomeQuestionListModel.DataBeanX) intent.getSerializableExtra("questionlistdataBean"));

        Urls = DataBean.getAttach().getImage().getOri();

        adapter = new MyImageAdapter(Urls, this);

        mViewPager.setAdapter(adapter);

        mViewPager.setCurrentItem(currentPosition, false);

        mTvImageCount.setText(currentPosition+1 + "/" + Urls.size());

        mViewPager.addOnPageChangeListener(new ViewPager.SimpleOnPageChangeListener() {

            @Override

            public void onPageSelected(int position) {

                super.onPageSelected(position);

                currentPosition = position;

                mTvImageCount.setText(currentPosition + 1 + "/" + Urls.size());

            }

        });

    }

    @Override

    public void onClick(View view) {

        switch (view.getId()) {

            case R.id.tv_save_image_photo:

　　　　　　　　　　//save image

                break;

        }

    }

}

图片列表页面跳转：

private void statPhotoViewActivity(int position) {

        Intent intent = new Intent(this, PhotoViewActivity.class);

        Bundle bundle = new Bundle();

        bundle.putSerializable("dataBean", mData);

        intent.putExtras(bundle);

        intent.putExtra("currentPosition", position);

        startActivity(intent);

    }
