How to level away Androids

[carriann]

I'm making a player on the Android. Dana next marking:

There is one Activity consisting of two three fragments:

1. The main fragment with the scrub.
2. Floating fragment. This block only shows up if the track plays

3. Navigation menu, like instagram.

   P.S. The floating fragment and menu are always down there! (sighs)android:layout_alignParentBottom="true")

Question: If the player doesn't play, then the floating fragment will be missing and filled with main fragment. Method layout.setPadding(0,0,0,125); It doesn't work. On different devices, derogations can be on the floor of the screen. How do I get it?

You're fixing the retraction value 125, but on different screens, try to convert the backset value to the corresponding screen density:

/**
 * This method converts device specific pixels to density independent pixels.
 *
 * @param px A value in px (pixels) unit. Which we need to convert into dp
 * @param context Context to get resources and device specific display metrics
 * @return A float value to represent dp equivalent to px value
 */
public static float convertPixelsToDp(float px, Context context){
    Resources resources = context.getResources();
    DisplayMetrics metrics = resources.getDisplayMetrics();
    float dp = px / (metrics.densityDpi /160f);
    return dp;
}
