How to determine real content size of devices without status bar, action bar and navigation bar ?

I wanna create a method that is used for all app. As following

private int getRealContentSize(){
int statusBarHeight = Common.getStatusBarHeight(this);
int actionBarHeight = Common.getActionBarHeight(this);
int navigationBarHeight = Common.getNavigationBarHeight(this);
DisplayMetrics metrics = new DisplayMetrics();
getWindowManager().getDefaultDisplay().getMetrics(metrics);
int totalHeight = statusBarHeight + actionBarHeight + navigationBarHeight;
Log.i("BAR", "status + " + statusBarHeight +
"; action bar + " + actionBarHeight +
"; navigation " + navigationBarHeight);
if(totalHeight < 50){
totalHeight = 50;
}
int thisHeight = metrics.heightPixels - totalHeight;
return thisHeight;
}

public static int getNavigationBarHeight(Context pContext){
Resources resources = pContext.getResources();
int resourceId = resources.getIdentifier("navigation_bar_height", "dimen", "android");
if (resourceId > 0) {
return resources.getDimensionPixelSize(resourceId);
}
return 0;
}

public static int getStatusBarHeight(Context pContext) {
Resources resources = pContext.getResources();
int resourceId = resources.getIdentifier("status_bar_height", "dimen", "android");
if (resourceId > 0) {
return resources.getDimensionPixelSize(resourceId);
}
return 0;
}

public static int getActionBarHeight(Context pContext) {
TypedValue tv = new TypedValue();
int actionBarHeight = 0;
if (pContext.getTheme().resolveAttribute(android.R.attr.actionBarSize, tv, true))
{
actionBarHeight = TypedValue.complexToDimensionPixelSize(tv.data,pContext.getResources().getDisplayMetrics());
}
return actionBarHeight;
}

I tested on 2.3.3, 4.0.3, 4.4.2. It seems like still get error when displaying. Does anyone have other like this or having some methods can solve this problem ?

Thanks all

Uhm, maybe I can solve in some cases. The following is my solution, it has been tested on emulators: 2.2(320x480), 2.3.3(480x800), 3.0(480x800), 4.0.3(480x800), 4.2.2(480x800)

private int getRealContentSize(){
int statusBarHeight = Common.getStatusBarHeight(this);
int actionBarHeight = Common.getActionBarHeight(this);
int navigationBarHeight = Common.getNavigationBarHeight(this);
DisplayMetrics metrics = new DisplayMetrics();
getWindowManager().getDefaultDisplay().getMetrics(metrics);
int totalHeight = 0;
if (android.os.Build.VERSION.SDK_INT < 14 /* 2.2<= x(320x480),(480x800) <= 4.0 */) {
totalHeight = (statusBarHeight + actionBarHeight + navigationBarHeight) * 2;
}
else if(android.os.Build.VERSION.SDK_INT >= 14 /* x(480x800) >= 4.0 */){
totalHeight = statusBarHeight + actionBarHeight;
}
int thisHeight = metrics.heightPixels - totalHeight;
return thisHeight;
}

If anyone has better solution, please share

Hi Pascal P,

Seems like your post does not include case "dimension without action bar, status bar and navigation bar". Which I want is "dimension is used to display content".
