Android Studio 全屏沉浸式透明状态栏效果
如何实现?
1.)首先实现全屏
第一种:继承主题特定主题
在Android API 19以上可以使用****.TranslucentDecor***有关的主题,自带相应半透明效果,Theme.Holo.NoActionBar.TranslucentDecor和Theme.Holo.Light.NoActionBar.TranslucentDecor两种主题为新增加的,所以要新建values-v19文件夹并创建styles文件添加如下代码
<style name="AppBaseTheme" parent="android:Theme.Holo.Light.NoActionBar.TranslucentDecor"> <!-- Customize your theme here. --> </style>
第二种:在activity中采用代码的方式
Android 4.4以上可以添加如下代码
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) { //透明状态栏 window.addFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS); //透明导航栏 window.addFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_NAVIGATION); }
Android 5.0 以上也可以使用下面的代码实现全屏
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) { 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); }
2.)解决状态栏占位问题
第一种:主题添加如下设置
<item name="android:fitsSystemWindows">true</item>
第二种:activity layout根目录添加下面代码
android:fitsSystemWindows="true"
第三种:通过Java代码设置
rootview.setFitsSystemWindows(true);
3.)状态栏导航栏设置背景色
4.4以上的可以采用修改contentView的背景色,或者动态添加一个view到contentView上
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) { //透明状态栏 window.addFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS); //透明导航栏 window.addFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_NAVIGATION); //设置contentview为fitsSystemWindows ViewGroup contentView = (ViewGroup) findViewById(android.R.id.content); View childAt = contentView.getChildAt(0); if (childAt != null) { childAt.setFitsSystemWindows(true); } //给statusbar着色 View view = new View(this); view.setLayoutParams(new ViewGroup.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, getStatusBarHeight(this))); view.setBackgroundColor(color); contentView.addView(view); }
动态获取StatusBarHeight函数如下
/** * 获取状态栏高度 * * @param context context * @return 状态栏高度 */ private static int getStatusBarHeight(Context context) { // 获得状态栏高度 int resourceId = context.getResources().getIdentifier("status_bar_height", "dimen", "android"); return context.getResources().getDimensionPixelSize(resourceId); }
动态获取NavigationBarHeight函数如下
/** * 获取导航栏高度 * * @param context context * @return 导航栏高度 */ public static int getNavigationBarHeight(Context context) { int resourceId = context.getResources().getIdentifier("navigation_bar_height", "dimen", "android"); return context.getResources().getDimensionPixelSize(resourceId); }
4.)贴出整体java代码实现方式
private void initWindows() { Window window = getWindow(); int color = getResources().getColor(R.color.wechatBgColor); if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) { 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); //设置状态栏颜色 window.setStatusBarColor(color); //设置导航栏颜色 window.setNavigationBarColor(getResources().getColor(R.color.footerBgColor)); ViewGroup contentView = ((ViewGroup) findViewById(android.R.id.content)); View childAt = contentView.getChildAt(0); if (childAt != null) { childAt.setFitsSystemWindows(true); } } else if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) { //透明状态栏 window.addFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS); //透明导航栏 window.addFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_NAVIGATION); //设置contentview为fitsSystemWindows ViewGroup contentView = (ViewGroup) findViewById(android.R.id.content); View childAt = contentView.getChildAt(0); if (childAt != null) { childAt.setFitsSystemWindows(true); } //给statusbar着色 View view = new View(this); view.setLayoutParams(new ViewGroup.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, getStatusBarHeight(this))); view.setBackgroundColor(color); contentView.addView(view); } if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M && useStatusBarColor) {//android6.0以后可以对状态栏文字颜色和图标进行修改 getWindow().getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN | View.SYSTEM_UI_FLAG_LIGHT_STATUS_BAR); } }
