I would like to know how I can read out the image height in pixels relative to the screen.
I have an image set in the middle of the screen which has a width and height of 100%. With the setting Maintain aspect ratio.
I would like to know how I can know the current height in pixels?
Hi ,
As of now, we do not have such functionality where we can convert dp to px. We have an existing FTR for the same. Request to create a Zendesk ticket to get more updates on the FTR.
To achieve your requirement, you need to write the FFI/NFI.
The below code snippet helps you to convert dp to px and vice versa.
public int dpToPx(int dp) {
DisplayMetrics displayMetrics = getContext().getResources().getDisplayMetrics();
return Math.round(dp * (displayMetrics.xdpi / DisplayMetrics.DENSITY_DEFAULT));
}
public int pxToDp(int px) {
DisplayMetrics displayMetrics = getContext().getResources().getDisplayMetrics();
return Math.round(px / (displayMetrics.xdpi / DisplayMetrics.DENSITY_DEFAULT));
}
Whatever the px you received as the return, you need to below step to get the percentages.
If the parent container Width/Height is in px.
Percentage of widget = (Pixel of widget container/ Pixel of Parent Container) * 100.
Note: The widgets height/width depends on the parent container.
Ok thanks, I will try it out. You don't happen to have an example app for this?
