Positioning images to fit all size screens

Question

I'm having a problem with positioning images,I need to position a lot images over another larger background image.

An image Like this

I have tried Absolute but it does not keep the position of the image say I wanted to put a clip art image of a board pin over the background image and need it pointing at a sun and when it's clicked I get a popup dialog, but then when I change the size of the emulator screen the clip art image is not at the same position I wanted it on the background image.

I first tried just putting the clip art on it with a image editor and used onTouch Listener but that didn't work out when I changed the size of the screen with the x and y coordinates. And tried Absolute Layout and that doesn seem to keep the position.

any ideas would help me big time thanks

Answer 1

AbsoluteLayout已弃用，因此最好将相对布局与dp一起使用。

You could use relative layout so you can use layout_below="@id/view1" , android:layout_toRightOf="@id/view2" , and android:layout_toLeftOf="@id/view3" . You can also use android:layout_marginLeft="10dip" , android:layout_marginRight="10dip" , android:layout_marginTop="10dip" , and android:layout_marginBottom="10dip" to move the views left/right and up/down relative to their current positions. There is also ALIGN_PARENT_LEFT, ALIGN_PARENT_RIGHT, ALIGN_PARENT_TOP, and ALIGN_PARENT_BOTTOM. Click here for more properties.

您可以使用其可绘制对象的getIntrinsicHeight()和getIntrinsicWidth()手动计算图像的可见宽度和高度，然后将Image的scaleType设置为FIT_XY （这样可以保存图像的比例，并且使其尺寸正确，而FIT_CENTER则不然）。
