Android: get real screen size
android, android-layout, screen
Solution
The following is my solution for getting the actual screen height on all APIs. When the device has a physical navigation bar, `dm.heightPixels` returns the actual height. When the device has a software navigation bar, it returns the total height minus the bar. I have only tested on a few devices but this has worked so far.
int navBarHeight = 0;
Resources resources = context.getResources();
int resourceId = resources.getIdentifier("navigation_bar_height", "dimen", "android");
if (resourceId > 0) {
navBarHeight = resources.getDimensionPixelSize(resourceId);
}
DisplayMetrics dm = new DisplayMetrics();
getWindowManager().getDefaultDisplay().getMetrics(dm);
boolean hasPhysicalHomeKey = KeyCharacterMap.deviceHasKey(KeyEvent.KEYCODE_HOME);
if (android.os.Build.VERSION.SDK_INT >= 17){
display.getRealSize(size);
int screen_width = size.x;
screen_height = size.y;
} else if (hasPhysicalHomeKey){
screen_height = dm.heightPixels;
} else {
screen_height = dm.heightPixels + navBarHeight;
}
Problem
Since API 17 it is possible to get the actual screen size of a phone with: ``` if (android.os.Build.VERSION.SDK_INT >= 17){ display.getRealSize(size); int screen_width = size.x; screen_height = size.y; } else {...} ``` I want to get the real screen size for APIs 8-16. What is the best way to handle the else condition in this case?
