GridViews are those in which you can arrange elements in a two dimensional grid.
It is what you see in the gallery where images are arranged. Here images are arranged in a two dimensional grid.
Copy the below code and save it as “MyGridView.java”
package com.pack;import android.app.Activity;import android.os.Bundle;import android.view.View;import android.widget.AdapterView;import android.widget.GridView;import android.widget.Toast;import android.widget.AdapterView.OnItemClickListener;public class MyGridView extends Activity {public void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.main);GridView gv = (GridView) findViewById(R.id.gridview);gv.setAdapter(new ImageAdapter(this));gv.setOnItemClickListener(new OnItemClickListener() {public void onItemClick(AdapterView parent, View v, int position, long id) {Toast.makeText(MyGridView.this, "" + position, Toast.LENGTH_SHORT).show();}});}}/********************************* End of MyGridView.java ****************************** **/ |
Now create another file named “Images.java” and copy the below code to it.
package com.pack;import android.content.Context;import android.view.View;import android.view.ViewGroup;import android.widget.BaseAdapter;import android.widget.GridView;lass="Apple-style-span" style="font-family: Times, 'Times New Roman', serif;">import android.widget.ImageView;public class Images extends BaseAdapter {private Context ctxt;public Images (Context c) {ctxt = c;}public int getCount() {return Ids.length;}public Object getItem(int position) {return null;}public long getItemId(int pos) {return 0;}public View getView(int pos, View convertView, ViewGroup parent) {ImageView imgView;if (convertView == null) {imgView = new ImageView(mContext);imgView.setLayoutParams(new GridView.LayoutParams(85, 85));imgView.setScaleType(ImageView.ScaleType.CENTER_CROP);imgView.setPadding(8, 8, 8, 8);} else {imgView = (ImageView) convertView;}imgView.setImageResource(Ids[pos]);return imgView;}private Integer[] Ids = {R.drawable.img_2, R.drawable.img_3,R.drawable.img_4, R.drawable.img_5,R.drawable.img_6, R.drawable.img_7,R.drawable.img_0, R.drawable.img_1,R.drawable.img_2, R.drawable.img_3,R.drawable.img_4, R.drawable.img_5,R.drawable.img_6, R.drawable.img_7,R.drawable.img_0, R.drawable.img_1,R.drawable.img_2, R.drawable.img_3,R.drawable.img_4, R.drawable.img_5,R.drawable.img_6, R.drawable.img_7};}/*********************************** End of Images.java**************************** **/ |
Note: Please make sure that you have images named img_0 to img_7 in your res/drawable folder.
