I have A grid View Gallery app with View Pager and Touch View feature enabled. . when a user clicks on a image on grid view it opens in fullscreen.When i click any image in GridView app crashes and this is wht i get in logs
(android.support.v4.view.ViewPager$LayoutParams cannot be cast to android.widget.RelativeLayout$LayoutParams) . Please help.
This is my MainActivity class:
public class MainActivity extends Activity {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// Set title for the GridView
setTitle("GridView");
// Get the view from grid_view.xml
setContentView(R.layout.activity_main);
// Set the images from ImageAdapter.java to GridView
GridView gridview = (GridView) findViewById(R.id.grid);
gridview.setAdapter(new ImageAdapter(this));
// Listening to GridView item click
gridview.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View v, int position, long id) {
// Launch ImageViewPager.java on selecting GridView Item
Intent i = new Intent(getApplicationContext(), ImageViewPager.class);
// Show a simple toast message for the item position
Toast.makeText(MainActivity.this, "" + position, Toast.LENGTH_SHORT).show();
// Send the click position to ImageViewPager.java using intent
i.putExtra("id", position);
// Start ImageViewPager
startActivity(i);
}
});
}
This is my ImageAdapter class:
public class ImageAdapter extends BaseAdapter {
private Context context;
public String Images[] = {("http://www.fashionlady.in/wp-content/uploads/2016/03/creative-punjabi-mehndi-design-2016.jpg"),
("https://lumiere-a.akamaihd.net/v1/images/uk_toystory_chi_woody_n_5b5a006f.png?region=0,0,300,300"),
("https://lumiere-a.akamaihd.net/v1/images/open-uri20150422-20810-10n7ovy_9b42e613.jpeg"),
("http://www.wetpaint.com/wp-content/uploads/2015/11/toy-story-20th-anniversary.jpg")};
public ImageAdapter(Context c) {
context = c;
}
@Override
public int getCount() {
return Images.length;
}
@Override
public Object getItem(int position) {
return Images[position];
}
@Override
public long getItemId(int position) {
return 0;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
ImageView imageview = new ImageView(context);
imageview.setScaleType(ImageView.ScaleType.CENTER_CROP);
imageview.setLayoutParams(new GridView.LayoutParams(240, 240));
Picasso.with(context).load(Images[position]).into(imageview);
return imageview;
}
}
This is my FullImageActivity class which should open a full image:
public class FullImageActivity extends AppCompatActivity {
TouchImageView img;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_full_image);
Intent i = getIntent();
List<ImageView> images = new ArrayList<>();
int position = i.getExtras().getInt("id");
ImageAdapter adapter = new ImageAdapter(this);
ImagePagerAdapter pageradapter = new ImagePagerAdapter(images);
img = (TouchImageView) findViewById(R.id.img);
images.add(img);
ViewPager viewpager = (ViewPager)findViewById(R.id.pager);
viewpager.setAdapter(pageradapter);
viewpager.setCurrentItem(position);
ViewGroup.LayoutParams params = img.getLayoutParams();
params.width = ViewGroup.LayoutParams.MATCH_PARENT;
params.height = 100;
img.requestLayout();
img.setMaxZoom(4f);
Picasso.with(getApplicationContext()).load(adapter.Images[position]).into(img);
}
}
This is my ImagePagerAdapter class:
public class ImagePagerAdapter extends PagerAdapter {
private List<ImageView> images;
public ImagePagerAdapter(List<ImageView> images) {
this.images = images;
}
@Override
public Object instantiateItem(ViewGroup container, int position) {
ImageView imageView = images.get(position);
container.addView(imageView);
return imageView;
}
@Override
public void destroyItem(ViewGroup container, int position, Object object) {
container.removeView(images.get(position));
}
@Override
public int getCount() {
return images.size();
}
@Override
public boolean isViewFromObject(View view, Object o) {
return view == o;
}
}
