setContentView(R.layout.parent_frame);//this one is the common
parent layout for all imageviews
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN);
imageView = new ImageView(this);
ImageButton next = (ImageButton) findViewById(R.id.next);
ImageButton back = (ImageButton) findViewById(R.id.back);
next.setOnClickListener(this);
back.setOnClickListener(this);
//show the default image
this.loadImage(imageArray[imageCounter]);
}
@Override
public void onClick(View v)
{
int imagePath = 0;
// TODO Auto-generated method stub
switch (v.getId())
{
case R.id.next:
Log.i("Tag","tag");
if(imageCounter < 25)
{
imagePath = imageArray[imageCounter];
}
imageCounter++;
break;
case R.id.back:
if(imageCounter > 0)
{
//imagePath =
}
break;
}
this.loadImage(imagePath);
}
private void loadImage(int imagePath)
{
imageView.setImageResource(imagePath);
//imageView.findViewById(R.id.imageWoL0);
//imageView.
}
the problem is that i am not getting imageview means my first image
R.drawable.image_w_lbl_0(see above array) is not being loaded.
