PhotoView图片的缩放与滑动
1、使用到的依赖是：
compile 'com.github.bumptech.glide:glide:3.7.0'
compile 'com.squareup.picasso:picasso:2.5.1'
两者皆可，都是图片的加载框架。
2.这是photoView的jar，可以自行下载一下。
3.代码：
//这是传递的集合，点击进行跳转，将图片的集合传过去。
listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView parent, View view, int position, long id) {
Intent in=new Intent(MainActivity.this,NextActivity.class);
in.putStringArrayListExtra("list",list);
startActivity(in);
}
});
4：接收到了传过来的值，并设置给fragment的参数，viewPager适配时采用FragmentPagerAdapter的适配器。
public class NextActivity extends AppCompatActivity {
private ArrayList list;
@Override
protected void onCreate(@Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.
next_layout
);
Intent intent = getIntent();
list = intent.getStringArrayListExtra("list");
ViewPager viewPager= (ViewPager) findViewById(R.id.
viewPager_next
);
//
设置适配器
viewPager.setAdapter(new FragAdapter(getSupportFragmentManager()));
}
private class FragAdapter extends FragmentPagerAdapter{
public FragAdapter(FragmentManager fm) {
super(fm);
}
@Override
public Fragment getItem(int position) {
FragmentNext f1=new FragmentNext();
Bundle bundle = new Bundle();//通过bundle传值的方式
bundle.putString("imageUrl",list.get(position));
f1.setArguments(bundle);
return f1;
}
@Override
public int getCount() {
return list.size();
}
}
}
5：在fragment中的设置图片的缩放
public class FragmentNext extends Fragment {
private View view;
@Nullable
@Override
public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
view = inflater.inflate(R.layout.
frag_layout
,null);
return view;
}
@Override
public void onActivityCreated(@Nullable Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
PhotoView photo= (PhotoView) view.findViewById(R.id.
pv
);
//拿到参数
Bundle bundle = getArguments();
String image = bundle.getString("imageUrl");
//设置图片
Glide.
with
(this).load(image).into(photo);
//
设置监听
photo.setOnPhotoTapListener(new PhotoViewAttacher.OnPhotoTapListener() {
@Override
public void onPhotoTap(View view, float v, float v1) {
getActivity().finish();
}
});
}
}
