Android适配器布局错误

Question

I have an adapter, I want to inflate a view but I can't.

This is my class code:

private static class RandomsAdapter extends BaseAdapter{
    private Randoms randoms;
    private RandomsAdapter(Randoms randoms) {
        this.randoms=randoms;
    }
    public void updateRandoms(Randoms randoms) {
        this.randoms=randoms;
        notifyDataSetChanged();
    }
    @Override
    public int getCount() {
        return randoms.size();
    }
    @Override
    public Random getItem(int position) {
        return randoms.get(position);
    }
    @Override
    public long getItemId(int position) {
        return 0;
    }
    public View getView(int position,View convertView,ViewGroup parent) {
        View view=convertView;

        if (convertView == null) {
            convertView=getLayoutInflater().inflate(R.layout.random_bars,parent,false);
        }
    }
}

I am getting an error for this line: convertView=getLayoutInflater().inflate(R.layout.random_bars,parent,false);

Error: Cannot make a static reference to the non-static method getLayoutInflater() from the type Activity

How can I resolve it?

Answer 1

you need Context inside this class& add it to constructor as

private RandomsAdapter(Randoms randoms, Context context) {
        this.randoms=randoms;
        this.mContext = context;
}

or remove "static" word from RandomsAdapter class definition

Answer 2

You need to pass Activity Context to your adapter. In the constructor:

private LayoutInflater inflater;

public RandomsAdapter(Context context, Randoms randoms) {
        this.randoms=randoms;
        this.inflater = LayoutInflater.from(context);
    }

Then you inflate layout as:

convertView=inflater.inflate(R.layout.random_bars,parent,false);
