android+图片分行浏览,Android使用ViewPager+PhotoView实现图片查看器

public class PhotoViewActivity extends AppCompatActivity implementsView.OnClickListener {public static final String TAG = PhotoViewActivity.class.getSimpleName();privatePhotoViewPager mViewPager;private intcurrentPosition;privateMyImageAdapter adapter;privateTextView mTvImageCount;privateTextView mTvSaveImage;private ListUrls;

}

});

}

@Overridepublic voidonClick(View view) {switch(view.getId()) {caseR.id.tv_save_image_photo:
