[android-developers] Re: Regarding using intents in the GridView and absolute layouts
Hi Kavitha,
Thanks for the reply. Samething I tryied, i wrote like this :
grid_main.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView parent, View v, int
position, long id) {
if(position==0){
Intent intent1 = new Intent(latest_icon_droid.this,
screen.class);
startActivity(intent1);
}
}
});
But then also, it is considering all the images are with position 0.
So when i clicked on any item, it is displaying the second screen,
which is not supposed to be displayed. :-(
Any idea, why is it like this?

[android-developers] Regarding using intents in the GridView and absolute layouts
Hi,
I am trying to write an application where I am trying to display
images along with the texts for the same. Images are displayed
properly on the grid.
Now I have one second screen, wherein On clicking only on the first
image, the seccond screen1 should be displayed. But now whats
happening is clicking on second, third, fourth and so on, images also
the same secocnd screen1 is displayed. I want to display the second
screen1 only if user clicks on first image. Could anybody please look
in to this and let me know where i am going wrong.
I have copied my files for your reference. I am using GridView for
displaying images and absolute layout for the texts for the images.

[android-developers] Re: setting an icon in the application.
Hi,
Thanks for the reply. Yes, I used the GridView and
SetOnItemClickListener. Now am able to click on any icon and display
the details on other screen. I have a second screen or activity,
clicking on first icon it should open the second screen and clicking
on second icon it should open the third screen . But now when I click
on any icon, the same second screen is displayed. I am using intents.
So I am not getting how to achieve this? Could you please help me.
This is my code:
package com.android.grid_hello;
import android.app.Activity;
import android.content.Context;
import android.os.Bundle;
import android.view.View;
import android.view.ViewGroup;
import android.widget.BaseAdapter;
import android.widget.Button;
import android.widget.GridView;
import android.widget.ImageView;
import android.widget.Toast;
import android.content.Intent;
import android.widget.AdapterView.OnItemClickListener;
import android.widget.AdapterView;
public class grid_hello extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.grid_new);
GridView gridview = (GridView) findViewById(R.id.gridview);
gridview.setAdapter(new ImageAdapter(this));
gridview.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView parent, View v, int
position, long id) {
Intent intent1 = new
Intent(grid_hello.this,second.class);
startActivity(intent1);
}
});
}
public class ImageAdapter extends BaseAdapter {
private Context mContext;
public ImageAdapter(Context c) {
mContext = c;
}
public int getCount() {
return mThumbIds.length;
}
public Object getItem(int position) {
return null;
}
public long getItemId(int position) {
return 0;
}
// create a new ImageView for each item referenced by the
Adapter
public View getView(int position, View convertView, ViewGroup
parent) {
ImageView imageView;
if (convertView == null) { // if it's not recycled,
initialize some attributes
imageView = new ImageView(mContext);
imageView.setLayoutParams(new
GridView.LayoutParams(85, 85));
imageView.setScaleType(ImageView.ScaleType.CENTER_CROP);
imageView.setPadding(8, 8, 8, 8);
} else {
imageView = (ImageView) convertView;
}
imageView.setImageResource(mThumbIds[position]);
return imageView;
}
// references to our images
private Integer[] mThumbIds = {
R.drawable.sample_0, R.drawable.sample_1,
R.drawable.sample_2, R.drawable.sample_3,
R.drawable.sample_4, R.drawable.sample_5,
