前言:

Android開發,對於狀態欄的修改,實在是不友好,沒什麼api能夠用, 不像ios那麼方便.可是ui又喜歡只搞ios一套. 沒辦法.各類翻源碼,寫反射.真的蛋疼.android

需求場景:

當toolbar及狀態欄須要爲白色或淺色時(如簡書),狀態欄因爲用的Light風格Theme,字體,圖標也都是白色,會看不清. 若是改變成黑色就很和諧了.ios

一.修改狀態欄顏色:

改變狀態欄顏色,能夠看看這篇文章傳送門:實現狀態欄(statusbar)漸變效果其實很簡單api

傳送門實現的效果:

這種方法實現的狀態欄變色,沒有黑色背景. bash

--------------------------------------分割線----------------------------------------ide

使用全屏模式實現的效果以下(QQ的效果):

很明顯的半透明黑色背景.工具

我用的手機是華爲,系統7.0oop

二.修改狀態欄字體:

通用工具類:字體

public class StatusBarUtil {

    /**

     * 適配4.4以上版本MIUIV、Flyme和6.0以上版本其餘Android

                result = 1;
            } else if (FlymeSetStatusBarLightMode(window, true)) {

activity中使用:

StatusBarUtil.setStatusBarLightMode(getWindow());
複製代碼

效果:

出現的問題:

1.statusbar背景色變成了colorPrimaryDark默認顏色, 可是個人配置是白色背景(具體配置代碼見最後).ui

分析緣由:

setSystemUiVisibility()會刷新view的屬性配置.
因爲statusbar默認使用colorPrimaryDark屬性.
因此顏色會變回默認顏色
複製代碼

此時步驟一設置背景的方法就會失效.

private void initStatusBar() {
        if (statusBarView == null) {
            int identifier = getResources().getIdentifier("statusBarBackground", "id", "android");
            statusBarView = getWindow().findViewById(identifier);
        }
        if (statusBarView != null) {
            statusBarView.setBackgroundResource(MVPConfig.statusDrawable);
        }
    }
複製代碼

緣由:當傳入的resid相同時,就不會再次去設置背景色.

解決辦法:

private void initStatusBar() {
        if (statusBarView == null) {
            int identifier = getResources().getIdentifier("statusBarBackground", "id", "android");
            statusBarView = getWindow().findViewById(identifier);
        }
        if (statusBarView != null) {
            statusBarView.setBackgroundDrawable(null);//在設置前將背景設置爲null;
          //statusBarView.setBackgroundResource(0); //這樣也能夠 
          statusBarView.setBackgroundResource(MVPConfig.statusDrawable);
        }
    }

修改後的效果:spa

    public static boolean isStatusBar() {
        return statusDrawable > 0;
    }

    public static void setToolbarDrawable(int toolbarBackgroundDrawable) {
        MVPConfig.toolbarBackgroundDrawable = toolbarBackgroundDrawable;
    }

    public static void setBackDrawable(int backDrawable) {
        MVPConfig.backDrawable = backDrawable;
    }

    public static void setIsStatusBarLight(boolean isStatusBarLight) {
        if (Build.VERSION.SDK_INT <= Build.VERSION_CODES.LOLLIPOP_MR1) {

                    getWindow().getDecorView().addOnLayoutChangeListener(new View.OnLayoutChangeListener() {
                        @Override
                        public void onLayoutChange(View v, int left, int top, int right, int bottom, int oldLeft, int oldTop, int oldRight, int oldBottom) {
                            initStatusBar();
                        }
                    });
                }
                mPresenter.initData();
                return false;
            }
        });

                statusBarView.setBackgroundDrawable(null);
            }
            statusBarView.setBackgroundResource(MVPConfig.statusDrawable);
        }
    }
    //子類經過複寫該方法,控制是否改變statusbar
    protected boolean isStatusBar() {
        return MVPConfig.isStatusBar();
    }
//子類經過複寫該方法,控制是否須要改變statusbar字體顏色
    protected boolean isStatusBarLight() {
        return MVPConfig.isStatusBarLight;
    }

四.補充:

6.0如下,5.0原生系統沒法修改字體顏色,用了個比較取巧的辦法,設置成半透明灰色.

public static void setStatusBarLightMode(Window window) {
        int type = getStatusBarLightMode(window);
        if (type == 1) {
            MIUISetStatusBarLightMode(window, true);
        } else if (type == 2) {
            FlymeSetStatusBarLightMode(window, true);
        } else if (type == 3) {
            window.getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_LIGHT_STATUS_BAR);
        } else {
            //5.0
            if (Build.VERSION.SDK_INT <= Build.VERSION_CODES.LOLLIPOP_MR1) {
                MVPConfig.statusDrawable = Color.parseColor("#33ffffff");
            }
        }
    }

複製代碼

因爲是直接修改window中的statusbarview的背景,而frgament依賴於activity,因此在activity與fragment直接跳轉時,狀態欄不是很適用. 好比: activity是藍色,fragment須要是白色,fragment須要經過window修改狀態欄顏色.有點麻煩.
