[android] How to change the status bar color in Android?

this is very easy way to do this without any Library: if the OS version is not supported - under kitkat - so nothing happend. i do this steps:

1. in my xml i added to the top this View:

<View
        android:id="@+id/statusBarBackground"
        android:layout_width="match_parent"
        android:layout_height="wrap_content" />

then i made this method:

 public void setStatusBarColor(View statusBar,int color){
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
           Window w = getWindow();
           w.setFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS,WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);
           //status bar height
           int actionBarHeight = getActionBarHeight();
           int statusBarHeight = getStatusBarHeight();
           //action bar height
           statusBar.getLayoutParams().height = actionBarHeight + statusBarHeight;
           statusBar.setBackgroundColor(color);
     }
}

also you need those both methods to get action Bar & status bar height:

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

public int getStatusBarHeight() {
    int result = 0;
    int resourceId = getResources().getIdentifier("status_bar_height", "dimen", "android");
    if (resourceId > 0) {
        result = getResources().getDimensionPixelSize(resourceId);
    }
    return result;
}

then the only thing you need is this line to set status bar color:

setStatusBarColor(findViewById(R.id.statusBarBackground),getResources().getColor(android.R.color.white));
