android-imageview

问题 In my application , one Relative Layout has totally three ImageView() 's . I want to save all the three imageviews as a single .png file to the device storage on a single button click. My code: Layout XML : <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" android:background="@color/make" > <ImageView android:id="@+id/imageView1" android:layout_width="wrap_content" android:layout_height="300dp"

My jpgs are no more than a megabyte in size. The run() method is called on a timer every 3-4 seconds or so and on click, but that shouldn't matter because from what I can tell using printlns the run() is only called once before

问题 My ImageView is displaying an image of a chess style board for a little game I'm making. It is covered by a GridView that displays the images of my pieces. I have it displaying underneath but it is not positioned properly. I want it to match exactly the edges of the GridView but don't know how.

问题 My aim is to show a SVG background image filling the whole screen's width, in a ConstraintLayout . A Button is superposed to this background image, that's why you can see in the mock-up below: The background image is the one that contains the stars.

The problem is the following: whether I bind the bottom side to the bottom side of the screen or not, the background image
