bilibili主题切换

第一步：

添加libs

 compile 'com.android.support:recyclerview-v7:25.3.1'
    //主题框架
    compile 'com.bilibili:magicasakura:0.1.5@aar'

需要添加recycleview否则会报错。

res文件中添加color.xml

其中

theme_color_primary

是最为重要的在bilibili封装的组件中设置需要设置的主题为这个颜色，然后调用代码就可以更改主题。

style中设置：

  false
        true
        true

可以选择不这样设置用组件中封装的toolbar

第二步设置代码：

appliction中设置：

 @Override
    public int replaceColorById(Context context, @ColorRes int colorId) {
        if (ThemeHelper.isDefaultTheme(context)) {
            return context.getResources().getColor(colorId);
        }
        String theme = getTheme(context);
        if (theme != null) {
            colorId = getThemeColorId(context, colorId, theme);
        }
        return context.getResources().getColor(colorId);
    }

    @Override
    public int replaceColor(Context context, @ColorInt int originColor) {
        if (ThemeHelper.isDefaultTheme(context)) {
            return originColor;
        }
        String theme = getTheme(context);
        int colorId = -1;

        if (theme != null) {
            colorId = getThemeColor(context, originColor, theme);
        }
        return colorId != -1 ? getResources().getColor(colorId) : originColor;
    }

    private String getTheme(Context context) {
        if (ThemeHelper.getTheme(context) == ThemeHelper.CARD_STORM) {
            return "blue";
        } else if (ThemeHelper.getTheme(context) == ThemeHelper.CARD_HOPE) {
            return "purple";
        } else if (ThemeHelper.getTheme(context) == ThemeHelper.CARD_WOOD) {
            return "green";
        } else if (ThemeHelper.getTheme(context) == ThemeHelper.CARD_LIGHT) {
            return "green_light";
        } else if (ThemeHelper.getTheme(context) == ThemeHelper.CARD_THUNDER) {
            return "yellow";
        } else if (ThemeHelper.getTheme(context) == ThemeHelper.CARD_SAND) {
            return "orange";
        } else if (ThemeHelper.getTheme(context) == ThemeHelper.CARD_FIREY) {
            return "red";
        }
        return null;
    }

    private
    @ColorRes
    int getThemeColorId(Context context, int colorId, String theme) {
        switch (colorId) {
            case R.color.theme_color_primary:
                return context.getResources().getIdentifier(theme, "color", getPackageName());
            case R.color.theme_color_primary_dark:
                return context.getResources().getIdentifier(theme + "_dark", "color", getPackageName());
            case R.color.theme_color_primary_trans:
                return context.getResources().getIdentifier(theme + "_trans", "color", getPackageName());
        }
        return colorId;
    }

    private
    @ColorRes
    int getThemeColor(Context context, int color, String theme) {
        switch (color) {
            case 0xfffb7299:
                return context.getResources().getIdentifier(theme, "color", getPackageName());
            case 0xffb85671:
                return context.getResources().getIdentifier(theme + "_dark", "color", getPackageName());
            case 0x99f0486c:
                return context.getResources().getIdentifier(theme + "_trans", "color", getPackageName());
        }
        return -1;
    }

application实现这个方法
implements ThemeUtils.switchColor

主题代码设置放在

SharePreference

 private static final String CURRENT_THEME = "theme_current";

    public static final int CARD_SAKURA = 0x1;
    public static final int CARD_HOPE = 0x2;
    public static final int CARD_STORM = 0x3;
    public static final int CARD_WOOD = 0x4;
    public static final int CARD_LIGHT = 0x5;
    public static final int CARD_THUNDER = 0x6;
    public static final int CARD_SAND = 0x7;
    public static final int CARD_FIREY = 0x8;

    public static SharedPreferences getSharePreference(Context context) {
        return context.getSharedPreferences("multiple_theme", Context.MODE_PRIVATE);
    }

    public static void setTheme(Context context, int themeId) {
        getSharePreference(context).edit()
                .putInt(CURRENT_THEME, themeId)
                .commit();
    }

    public static int getTheme(Context context) {
        return getSharePreference(context).getInt(CURRENT_THEME, CARD_SAKURA);
    }

    public static boolean isDefaultTheme(Context context) {
        return getTheme(context) == CARD_SAKURA;
    }

    public static String getName(int currentTheme) {
        switch (currentTheme) {
            case CARD_SAKURA:
                return "THE SAKURA";
            case CARD_STORM:
                return "THE STORM";
            case CARD_WOOD:
                return "THE WOOD";
            case CARD_LIGHT:
                return "THE LIGHT";
            case CARD_HOPE:
                return "THE HOPE";
            case CARD_THUNDER:
                return "THE THUNDER";
            case CARD_SAND:
                return "THE SAND";
            case CARD_FIREY:
                return "THE FIREY";
        }
        return "THE RETURN";
    }

调用这个方法更新主题：

  ThemeUtils.refreshUI(MainActivity.this, new ThemeUtils.ExtraRefreshable() {
                        @Override
                        public void refreshGlobal(Activity activity) {
                            //for global setting, just do once
                            if (Build.VERSION.SDK_INT >= 21) {
                                final MainActivity context = MainActivity.this;
                                ActivityManager.TaskDescription taskDescription = new ActivityManager.TaskDescription(null, null, ThemeUtils.getThemeAttrColor(context, android.R.attr.colorPrimary));
                                setTaskDescription(taskDescription);
                                getWindow().setStatusBarColor(ThemeUtils.getColorById(context, R.color.theme_color_primary));
                            }
                        }

                        @Override
                        public void refreshSpecificView(View view) {
                        }
                    }
            );

官网上的代码，下下来后可以仿写。

重要的是设置颜色时使用theme_color_primary
