I have View-pager with nine images. I am setting images in view using bitmap. When i choose nine images from gallery first time, its show all nine images perfectly. Also when i choose another nine images from gallery with keep first first or second view same,view-pager display with updated images. But my problem is when I am trying to change all nine images with first and second. they display error like OutOfMemoryEror. so my question is. How to update first and second(next) view in view-pager. any one can help me.? than x in advance.
Activity code
if(ab != null){
arr = ab.split(",");
for(int i = 0; i <arr.length; i++){
// Toast.makeText(getApplicationContext(), "done: "+ arr[i], Toast.LENGTH_LONG).show();
imgFile = new File(arr[i]);
if(imgFile.exists()){
myBitmap = BitmapFactory.decodeFile(imgFile.getAbsolutePath());
System.out.println("This my - bit : "+myBitmap+"ara - lenth : "+arr.length);
bitmapArray.add(myBitmap);
System.out.println("This bit-aray : "+bitmapArray.size()+" : "+bitmapArray.size() + "ara pos : "+arr[i]);
//Toast.makeText(getApplicationContext(), "This is bitmap array : "+ bitmapArray, Toast.LENGTH_LONG).show();
}
}
}else{
}
Adapter code
if(l == 1){
// layout.removeView(imageView);
// container.removeView(layout);
if(bitmapArray != null){
for(int j = 0; j < bitmapArray.size(); j++){
if(j == position){
j = position;
imageView.setImageBitmap(bitmapArray.get(j));
}
}
} //Toast.makeText(getApplicationContext(), ""+bitmapArray.get(j)+"size "+bitmapArray.size(), Toast.LENGTH_SHORT).show();
else{
imageView.setImageResource(res[position]);
bitarray.clear();
bitmapArray.clear();
sharedpreferences.edit().remove("imgpath").commit();
}
}
if(l == 2){
//layout.removeView(imageView);
//container.removeView(layout);
if(bitmapArray != null){
for(int j = 0; j < bitmapArray.size(); j++){
if(j == position){
j = position;
imageView.setImageBitmap(bitmapArray.get(j));
}
}
} //Toast.makeText(getApplicationContext(), ""+bitmapArray.get(j)+"size "+bitmapArray.size(), Toast.LENGTH_SHORT).show();
else{
imageView.setImageResource(res[position]);
bitarray.clear();
bitmapArray.clear();
sharedpreferences.edit().remove("imgpath").commit();
}
}
