关于打包签名时 出现错误---Error:Error: Expected resource of type styleable [ResourceType]

@SuppressWarnings("ResourceType") //加上这个注释 忽略该警告 就可以编译打包签名
public AlignTextView(Context context, AttributeSet attrs) {
super(context, attrs);
setTextIsSelectable(false);

int[] attributes = new int[]{android.R.attr.lineSpacingExtra, android.R.attr.lineSpacingMultiplier};
TypedArray arr = context.obtainStyledAttributes(attrs, attributes);
lineSpacingAdd = arr.getDimensionPixelSize(0, 0);
lineSpacingMultiplier = arr.getFloat(1, 1.0f);
originalPaddingBottom = getPaddingBottom();
arr.recycle();
