Load images from tableLayout android
I have five rows imageView, but this code load only 4 rows? why?
Java code
tl = (TableLayout) findViewById(R.id.tableLayout);
for (int i = 0; i < tl.getChildCount(); i++) {
View v = tl.getChildAt(i);
if (v instanceof TableRow) {
for (int j = 0; j < ((TableRow) v).getChildCount(); j++) {
View innerView = ((TableRow) v).getChildAt(j);
if (innerView instanceof ImageView) {
imageList.add((ImageView) innerView);
idList.add(innerView.getId());
}
}
}
}

I can comparing two imageView? eg image.get(1).getdrawable()==image.get(2).getdrawable()?
No, by this way it just comparing whether they are the same object or not. In this case this will be false. But, if you want to compare the images of the imageviews, then you should get theirs bitmap then use sameAs method.
//comapre objects returns false
Log.i("EQ", (imageList.get(0).getDrawable().equals(imageList.get(1).getDrawable())) + "");
Log.i("EQ", imageList.get(0).getDrawable().toString()); //android.graphics.drawable.BitmapDrawable@89c323c
Log.i("EQ", imageList.get(1).getDrawable().toString()); //android.graphics.drawable.BitmapDrawable@837dbc5
BitmapDrawable bitmapDrawable0 = ((BitmapDrawable) imageList.get(0).getDrawable());
Bitmap bitmap0 = bitmapDrawable0 .getBitmap();
BitmapDrawable bitmapDrawable1 = ((BitmapDrawable) imageList.get(1).getDrawable());
Bitmap bitmap1 = bitmapDrawable1 .getBitmap();
//comapre the image returns true
Log.i("EQ2", Boolean.toString(bitmap0.sameAs(bitmap1)));
Where i called toString() it shows that, they are not the same object, although they are holding the same image as sameAs indicating.
Note: instead of equals() method, "==" operator would do the same, there is no difference
