'setbackgrounddrawable() 'is deprecated, setbackgrounddrawable is obsolete

setBackgroundDrawable() stay API 16（4.1） It's out of date

4.1 Then there are two ways to replace ：

a、setBackgroundResource

b、setBackground

for example ：

textView.setBackgroundResource(R.drawable.icon);
textView.setBackground(ContextCompat.getDrawable(this, R.drawable.icon));

Copy

setBackgroundResource Method is called internally setBackground Method , and setBackground The internal call is still setBackgroundDrawable Method

setBackground Source code ：

public void setBackground(Drawable background) {
        //noinspection deprecation
        setBackgroundDrawable(background);// here 
    }

Copy

setBackgroundResource Source code ：

@RemotableViewMethod
    public void setBackgroundResource(@DrawableRes int resid) {
        if (resid != 0 && resid == mBackgroundResource) {
            return;
        }

        Drawable d = null;
        if (resid != 0) {
            d = mContext.getDrawable(resid);
        }
        setBackground(d);// Notice the call here 

        mBackgroundResource = resid;
    }
