在单个Activity或BaseActivity加入这三个方法即可
/** * colorID 状态栏的颜色，可以是透明 * @param colorID */ public void setStatusBarColor(int colorID) { if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) { setStatusBarColorLOLLIPOP(colorID); } else if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) { setTranslucentStatus(true); SystemBarTintManager tintManager = new SystemBarTintManager(this); tintManager.setStatusBarTintEnabled(true); tintManager.setNavigationBarTintEnabled(true); tintManager.setStatusBarTintColor(getResources().getColor(colorID)); } } @TargetApi(21) private void setStatusBarColorLOLLIPOP(int colorID) { Window window = getWindow(); window.clearFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS | WindowManager.LayoutParams.FLAG_TRANSLUCENT_NAVIGATION); window.getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN | View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION | View.SYSTEM_UI_FLAG_LAYOUT_STABLE); window.addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS); window.setStatusBarColor(getResources().getColor(colorID)); window.setNavigationBarColor(Color.TRANSPARENT); } @TargetApi(19) private void setTranslucentStatus(boolean on) { Window win = getWindow(); WindowManager.LayoutParams winParams = win.getAttributes(); final int bits = WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS; if (on) { winParams.flags |= bits; } else { winParams.flags &= ~bits; } win.setAttributes(winParams); }自定义状态栏在一些特定场合会导致一些问题出现，比如windowSoftInputMode失效（登录页软键盘问题）pairscrollview开源控件使用异常（解决scrollview嵌套webView和listview滑动不到底部问题），后面都会介绍解决方法。
