quatja / vorolay Goto Github PK

Not sure what's going on here but I keep getting this error

which refers to this part of the library

This is my adapter for the listview

package com.example.frido.rando.Utilities;

import android.content.Context;
import android.graphics.Color;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.BaseAdapter;
import android.widget.ImageView;
import android.widget.TextView;

import com.example.frido.rando.R;

import java.io.File;
import java.util.ArrayList;
import java.util.Random;

import butterknife.BindView;
import butterknife.ButterKnife;
import quatja.com.vorolay.VoronoiView;

public class VoronoAdapter extends BaseAdapter {
    private Context context;
    private LayoutInflater layoutInflater;
    private ArrayList<String> imageURLs;
    private File filePath;

    public VoronoAdapter(ArrayList<String> imageURLs, Context context) {
        this.imageURLs = imageURLs;
        this.context = context;
        this.layoutInflater = LayoutInflater.from(context);
    }

    @Override
    public int getCount() {
        return imageURLs.size();
    }

    @Override
    public Object getItem(int position) {
        return imageURLs.get(position);
    }

    @Override
    public long getItemId(int position) {
        return position;
    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        ViewHolder holder;
        if (convertView == null) {
            convertView = layoutInflater.inflate(R.layout.vorono_template, parent, false);
            holder = new ViewHolder(convertView);
            convertView.setTag(holder);


            for (int i = 0; i < 20; i++) {
                View view = layoutInflater.inflate(R.layout.vorono_item_for_template, null, false);
                holder.voronoi.addView(view);

                ImageView layout = (ImageView) view.findViewById(R.id.itemVoronoLayout);
                Random rnd = new Random();
                int color = Color.argb(255, rnd.nextInt(256), rnd.nextInt(256), rnd.nextInt(256));
                layout.setBackgroundColor(color);
            }
        } else {
            holder = (ViewHolder) convertView.getTag();
        }




        return convertView;
    }


    static class ViewHolder{
        @BindView(R.id.voronoTemplateForList) VoronoiView voronoi;


        public ViewHolder(View view){
            ButterKnife.bind(this,view);
        }
    }
}
```

I set up a clickListener for the views in the vorolay layout. When I click a region on an imageView that's "overlapped" by another, the other imageView is activated (see attached image).

is there any settings I can configure?

the following are my codes

    for (int i = 0; i < count; i++) {
        RelativeLayout rl = (RelativeLayout) layoutInflater.inflate(R.layout.item_voronoi, null, false);

        ImageView iv = ( ImageView) rl.findViewById(R.id.image);

       //add a callback when the image is clicked
        int value = i;
        iv.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                Log.d("TEST", "item clicked: "+ value);
            }
        }); 

        loadImage(iv, uri);  //this method populates the image

        vv.addView(rl); //this is the VoronoiView
    }  

Hey I've been trying to use your library but when I add it to my layout I get this error

Hey, first of all I would like to say this is an amazing library :)
Is there a way to make it not random? as in the same picture will go to the same spot with the exact same shape every time? Even when playing with generation_type and setGenerationType it still adds random shapes

app works correctly on emulator with API24, but is not properly cropped on an API19 (android 4.2.2) device.

the code for adding the view is

for (int i = 0; i < count; i++) {
        RelativeLayout rl = (RelativeLayout) layoutInflater.inflate(R.layout.item_voronoi, null, false);
        ImageView view = ( ImageView) rl.findViewById(R.id.image);  
        view.setImageURI(uri); 
        vv.addView(rl);
    }

and the xml is

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content">
 
    <ImageView
        android:id="@+id/image"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:scaleType="centerCrop" />

</RelativeLayout>

My code:
voronoiView = (VoronoiView) findViewById(R.id.voronoi); LayoutInflater layoutInflater = getLayoutInflater(); for (int i = 0; i < 15; i++) { ImageView view = (ImageView) layoutInflater.inflate(R.layout.item_iv, null, false); view.setImageResource(R.drawable.p2_480); voronoiView.addView(view); }
