Android Compat 库

compat

正确使用 support 库

• View#setBackground
  minSdk<16 时必须用setBackgroundDrawable设置背景，
  阻止Lint警告的兼容做法，自己写一套方法处理

public class ViewCompat {
    public static void setBackground(View targetView, Drawable drawable) {
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN) {
            targetView.setBackground(drawable);
        } else {
            //noinspection deprecation
            targetView.setBackgroundDrawable(drawable);
        }
    }
}

在Support library 25+以后ViewCompat自带了setBackground方法

ViewCompat.setBackground(mView, background);

• Resources#getColorStateList
  使用ContextCompat#getColorStateList替换

public static final ColorStateList getColorStateList(Context context, @ColorRes int id)

• Resources#getDrawable
  使用Contextpat#getDrawable替换

public static final Drawable getDrawable(Context context, @DrawableRes int id)
