问题
I am creating a dynamic table whose rows contains a imageview and a textview. My problem is this imageview is taking full size of original image but I want to change the size of imageview.I have used setLayoutParams which has no effect. As an alternative I also used textview instead of imageview and set image as textview's background and used setWidth and setHeight but it has the same problem. Plz Help Me.
回答1:
Have you tried the scaleType-Attribute?
Check out the setMaxWidth and setMaxHeight-methods of the ImageView-class:
To set an image to be a maximum of 100 x 100 while preserving the original aspect ratio, do the following: 1) set adjustViewBounds to true 2) set maxWidth and maxHeight to 100 3) set the height and width layout params to WRAP_CONTENT.

Assuming your image is a drawable resource, you can use ScaleDrawable instead, and use the xml attributes android:scaleHeight and android:scaleWidth to shrink your image.

OK I found the Solution
Resizing an ImageView within a TableLayout programmatically
回答4:
Try changing your ImageView's layout_width and layout_height inside the layout file to some constant values measured in sp, for example 100sp. This will make all ImageViews look the same.
