Android开发之修改状态栏背景色&设置状态栏背景透明

2.案例使用 public class StatusBarColor{ //改变状态栏颜色 public static void setStatusBarColor(Activity activity,int statusColor){ Window window = activity.getWindow(); //取消透明状态栏 window.clearFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS); //添加Flag把状态栏设为可绘制模式 window.addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS); //设置状态栏颜色 window.setStatusBarColor(statusColor); //设置系统状态栏处于可见状态 window.getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_VISIBLE); //让view不根据系统窗口来调整自己的布局 ViewGroup mContentView = (ViewGroup) window.findViewById(Window.ID_ANDROID_CONTENT); View mChildView = mContentView.getChildAt(0); if (mChildView != null) { ViewCompat.setFitsSystemWindows(mChildView, false); ViewCompat.requestApplyInsets(mChildView); } } //将状态栏设置为透明 public static void translucentStatusBar(Activity activity, boolean hideStatusBarBackground) { Window window = activity.getWindow(); //添加Flag把状态栏设为可绘制模式 window.addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS); if (hideStatusBarBackground) { //如果为全透明模式，取消设置Window半透明的Flag window.clearFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS); //设置状态栏为透明 window.setStatusBarColor(Color.TRANSPARENT); //设置window的状态栏不可见 window.getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_LAYOUT_STABLE | View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN); } else { //如果为半透明模式，添加设置Window半透明的Flag window.addFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS); //设置系统状态栏处于可见状态 window.getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_VISIBLE); } //view不根据系统窗口来调整自己的布局 ViewGroup mContentView = (ViewGroup) window.findViewById(Window.ID_ANDROID_CONTENT); View mChildView = mContentView.getChildAt(0); if (mChildView != null) { ViewCompat.setFitsSystemWindows(mChildView, false); ViewCompat.requestApplyInsets(mChildView); } } }
