在Android应用程序中设置标题栏渐变

Question

I want to set a gradient on my application title bar (from #F55B53 to #FFFF00 ), with this following code :

GradientDrawable gd = new GradientDrawable(GradientDrawable.Orientation.TOP_BOTTOM, new int[] {0xF55B53,0xFFFF00});
View title = getWindow().findViewById(android.R.id.title);
View titleBar = (View) title.getParent();
titleBar.setBackgroundDrawable(gd);

But eclipse tell me :

The method setBackgroundDrawable(Drawable) from the type view is deprecated

What I should do?

Answer 1

Most of the time you get a deprecation warning, it comes along with the correct way of doing it. If you go to the View class documentation , you will notice that the setBackgroundDrawable(Drawable background) method says:

This method was deprecated in API level 16. use setBackground(Drawable) instead

Depending on the android version you are targeting you might want to continue using the deprecated one.

Answer 2

titleBar.setBackgroundDrawable(gd);

change the code

int sdk = android.os.Build.VERSION.SDK_INT;
if(sdk < android.os.Build.VERSION_CODES.JELLY_BEAN) {
    setBackgroundDrawable()
} else {
    setBackground();
}
