класс Adapter:

  package com.app.redbuslayout; 

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

public class CustomGrid extends BaseAdapter{ 
    private Context mContext; 

    private final int[] Imageid; 
     public CustomGrid(Context c,int[] Imageid) { 
      mContext = c; 
      this.Imageid = Imageid; 

     } 
    @Override 
    public int getCount() { 
     // TODO Auto-generated method stub 
     return Imageid.length; 
    } 
    @Override 
    public Object getItem(int position) { 
     // TODO Auto-generated method stub 
     return null; 
    } 
    @Override 
    public long getItemId(int position) { 
     // TODO Auto-generated method stub 
     return 0; 
    } 
    @Override 
    public View getView(int position, View convertView, ViewGroup parent) { 
     // TODO Auto-generated method stub 
     View grid; 
     LayoutInflater inflater = (LayoutInflater) mContext 
     .getSystemService(Context.LAYOUT_INFLATER_SERVICE); 
      if (convertView == null) { 
      grid = new View(mContext); 
     grid = inflater.inflate(R.layout.row_grid, null); 

      ImageView imageView = (ImageView)grid.findViewById(R.id.grid_image); 

      imageView.setImageResource(Imageid[position]); 
      } else { 
      grid = (View) convertView; 
      } 



     return grid; 
    } 
} 

В моем приложении с JSON я maxrows и maxcolumns. Основываясь на maxrow и maxcolumn, я хочу создать сетку с таким же количеством столбцов и строк. Каждая сетка содержит одно и то же изображение.

Как я могу создать это gridview динамически?

Answer 1

LazyAdapter adapter; 

adapter = new LazyAdapter(this, Col , Height , Width, SeatNo); 
     grid.setAdapter((ListAdapter) adapter); 

и LazyAdapter продолжается с BaseAdapter класса

public LazyAdapter(Activity a, String[] d, String[] textname, 
      String catID, String subCatIDD) { 
     activity = a; 
     data = d; 
     textdataamag = textname; 
     this.catID = catID; 
     this.subCatIDD = subCatIDD; 
     inflater = (LayoutInflater) activity 
       .getSystemService(Context.LAYOUT_INFLATER_SERVICE); 

    } 

это конструктор придерживается мнения, что вы отправляете из GridView класса.

public View getView(int position, View convertView, ViewGroup parent) { 
//here you get handle your view 

ex.

View vi = convertView; 
     if (convertView == null) 
      vi = inflater.inflate(R.layout.masterindex, null); 

     TextView text = (TextView) vi.findViewById(R.id.channelTXT); 
     ImageView image = (ImageView) vi.findViewById(R.id.channelIMG); 

     } 

return view
