前言:
Android開發,對于狀態欄的修改,實在是不友好,沒什么api可以用,不像ios那么方便.但是ui又喜歡只搞ios一套.沒辦法.各種翻源碼,寫反射.真的蛋疼.
需求場景:
當toolbar及狀態欄需要為白色或淺色時(如簡書),狀態欄由于用的Light風格Theme,字體,圖標也都是白色,會看不清.如果改變成黑色就很和諧了.
一.修改狀態欄顏色:
改變狀態欄顏色,可以看看這篇文章.傳送門:實現狀態欄(statusbar)漸變效果其實很簡單
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.
使用全屏模式實現的效果如下(QQ的效果):
很明顯的黑色背景.
我用的手機是華為,系統7.0
二.修改狀態欄字體:
通用工具類:
public class StatusBarUtil { /** * 設置狀態欄黑色字體圖標， * 適配4.4以上版本MIUIV、Flyme和6.0以上版本其他Android * * @return 1:MIUUI 2:Flyme 3:android6.0 */ public static int getStatusBarLightMode(Window window) { int result = 0; if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) { if (MIUISetStatusBarLightMode(window, true)) { result = 1; } else if (FlymeSetStatusBarLightMode(window, true)) { result = 2; } else if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) { window.getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_LIGHT_STATUS_BAR); result = 3; } else {//5.0 } } return result; } /** * 已知系統類型時，設置狀態欄黑色字體圖標。 * 適配4.4以上版本MIUIV、Flyme和6.0以上版本其他Android */ 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 } } /** * 清除MIUI或flyme或6.0以上版本狀態欄黑色字體 */ public static void StatusBarDarkMode(Window window) { int type = getStatusBarLightMode(window); if (type == 1) { MIUISetStatusBarLightMode(window, false); } else if (type == 2) { FlymeSetStatusBarLightMode(window, false); } else if (type == 3) { window.getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_VISIBLE); } } /** * 設置狀態欄圖標為深色和魅族特定的文字風格 * 可以用來判斷是否為Flyme用戶 * * @param window 需要設置的窗口 * @param dark 是否把狀態欄字體及圖標顏色設置為深色 * @return boolean 成功執行返回true */ public static boolean FlymeSetStatusBarLightMode(Window window, boolean dark) { boolean result = false; if (window != null) { try { WindowManager.LayoutParams lp = window.getAttributes(); Field darkFlag = WindowManager.LayoutParams.class .getDeclaredField("MEIZU_FLAG_DARK_STATUS_BAR_ICON"); Field meizuFlags = WindowManager.LayoutParams.class .getDeclaredField("meizuFlags"); darkFlag.setAccessible(true); meizuFlags.setAccessible(true); int bit = darkFlag.getInt(null); int value = meizuFlags.getInt(lp); if (dark) { value |= bit; } else { value &= ~bit; } meizuFlags.setInt(lp, value); window.setAttributes(lp); result = true; } catch (Exception e) { } } return result; } /** * 設置狀態欄字體圖標為深色，需要MIUIV6以上 * * @param window 需要設置的窗口 * @param dark 是否把狀態欄字體及圖標顏色設置為深色 * @return boolean 成功執行返回true */ public static boolean MIUISetStatusBarLightMode(Window window, boolean dark) { boolean result = false; if (window != null) { Class clazz = window.getClass(); try { int darkModeFlag = 0; Class layoutParams = Class.forName("android.view.MiuiWindowManager$LayoutParams"); Field field = layoutParams.getField("EXTRA_FLAG_STATUS_BAR_DARK_MODE"); darkModeFlag = field.getInt(layoutParams); Method extraFlagField = clazz.getMethod("setExtraFlags", int.class, int.class); if (dark) { extraFlagField.invoke(window, darkModeFlag, darkModeFlag);//狀態欄透明且黑色字體 } else { extraFlagField.invoke(window, 0, darkModeFlag);//清除黑色字體 } result = true; } catch (Exception e) { } } return result; }}activity中使用:
StatusBarUtil.setStatusBarLightMode(getWindow());
效果:
出現的問題:
1.statusbar背景色變成了colorPrimaryDark默認顏色,但是我的配置是白色背景(具體配置代碼見最后).
分析原因:
setSystemUiVisibility()會刷新view的屬性配置.由于statusbar默認使用colorPrimaryDark屬性.所以顏色會變回默認顏色
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); } }原因: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為null; statusBarView.setBackgroundResource(MVPConfig.statusDrawable); } }修改后的效果:
三.完整代碼:
1.MvpConfig
public class MVPConfig { public static int statusDrawable; public static int toolbarBackgroundColor; public static int toolbarBackgroundDrawable; public static int backDrawable; public static boolean isStatusBarLight; public static void setStatusbarDrawable(@DrawableRes int statusDraw) { statusDrawable = statusDraw; } 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) { MVPConfig.statusDrawable = Color.parseColor("#33ffffff"); } MVPConfig.isStatusBarLight = isStatusBarLight; }2.Application中
@Override public void onCreate() { super.onCreate(); MVPConfig.setToolbarDrawable(R.color.white); MVPConfig.setStatusbarDrawable(R.color.white); MVPConfig.setBackDrawable(R.drawable.back); MVPConfig.setIsStatusBarLight(true);}3.BaseActivity
@Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); //延時加載數據. Looper.myQueue().addIdleHandler(new MessageQueue.IdleHandler() { @Override public boolean queueIdle() { if (isStatusBarLight()) { StatusBarUtil.setStatusBarLightMode(getWindow()); } if (isStatusBar()) { initStatusBar(); 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; } }); } private void initStatusBar() { if (statusBarView == null) { int identifier = getResources().getIdentifier("statusBarBackground", "id", "android"); statusBarView = getWindow().findViewById(identifier); } if (statusBarView != null) { if (isStatusBarLight()) { statusBarView.setBackgroundDrawable(null); } statusBarView.setBackgroundResource(MVPConfig.statusDrawable); } } //子類通過復寫該方法,控制是否改變statusbar protected boolean isStatusBar() { return MVPConfig.isStatusBar(); }//子類通過復寫該方法,控制是否需要改變statusbar字體顏色 protected boolean isStatusBarLight() { return MVPConfig.isStatusBarLight; }四.補充:
6.0以下,5.0原生系統無法修改字體顏色,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"); } } }由于是直接修改window中的statusbarview的背景,而frgament依賴于activity,所以在activity與fragment直接跳轉時,狀態欄不是很適用.比如:activity是藍色,fragment需要是白色,fragment需要通過window修改狀態欄顏色.有點麻煩.
