Android获取当前主题的颜色属性

安卓代码中获取当前主题颜色方法的两种方法：

• 第一种方法:

        TypedArray array = getTheme().obtainStyledAttributes(new int[]{
                android.R.attr.colorBackground,
                android.R.attr.textColorPrimary,
                android.R.attr.colorPrimary,
                android.R.attr.colorPrimaryDark,
                android.R.attr.colorAccent,
        });
        backgroundColor = array.getColor(0, 0xFF00FF);
        textColor = array.getColor(1, 0xFF00FF);
        colorPrimary = array.getColor(2, getResources().getColor(R.color.colorPrimary));
        colorPrimaryDark = array.getColor(3, getResources().getColor(R.color.colorPrimaryDark));
        colorAccent = array.getColor(4, getResources().getColor(R.color.colorAccent));
        array.recycle();

• 第二种方法:

    public int getColorPrimary(){
        TypedValue typedValue = new TypedValue();
        getTheme().resolveAttribute(R.attr.colorPrimary, typedValue, true);
        return typedValue.data;
    }

    public int getDarkColorPrimary(){
        TypedValue typedValue = new  TypedValue();
        getTheme().resolveAttribute(R.attr.colorPrimaryDark, typedValue, true);
        return typedValue.data;
    }

    public int getColorAccent(){
        TypedValue typedValue = new  TypedValue();
        getTheme().resolveAttribute(R.attr.colorAccent, typedValue, true);
        return typedValue.data;
    }
