如何實現?
1.)首先實現全屏
第一種:繼承主題特定主題
在Android API 19以上可以使用****.TranslucentDecor***有關的主題,自帶相應半透明效果,Theme.Holo.NoActionBar.TranslucentDecor和Theme.Holo.Light.NoActionBar.TranslucentDecor兩種主題為新增加的,所以要新建values-v19文件夾並創建styles文件添加如下代碼
<style name="AppBaseTheme" parent="android:Theme.Holo.Light.NoActionBar.TranslucentDecor"> <!-- Customize your theme here. --> </style>
第二種:在activity中采用代碼的方式
Android 4.4以上可以添加如下代碼
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) { //透明狀態欄 window.addFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS); //透明導航欄 window.addFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_NAVIGATION); }
Android 5.0 以上也可以使用下面的代碼實現全屏
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.)解決狀態欄占位問題
第一種:主題添加如下設置
<item name="android:fitsSystemWindows">true</item>
第二種:activity layout根目錄添加下面代碼
android:fitsSystemWindows="true"
第三種:通過Java代碼設置
rootview.setFitsSystemWindows(true);
3.)狀態欄導航欄設置背景色
4.4以上的可以采用修改contentView的背景色,或者動態添加一個view到contentView上
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) { //透明狀態欄 window.addFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS); //透明導航欄 window.addFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_NAVIGATION); //設置contentview為fitsSystemWindows ViewGroup contentView = (ViewGroup) findViewById(android.R.id.content); View childAt = contentView.getChildAt(0); if (childAt != null) { childAt.setFitsSystemWindows(true); } //給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); }
動態獲取StatusBarHeight函數如下
/** * 獲取狀態欄高度 * * @param context context * @return 狀態欄高度 */ private static int getStatusBarHeight(Context context) { // 獲得狀態欄高度 int resourceId = context.getResources().getIdentifier("status_bar_height", "dimen", "android"); return context.getResources().getDimensionPixelSize(resourceId); }
動態獲取NavigationBarHeight函數如下
/** * 獲取導航欄高度 * * @param context context * @return 導航欄高度 */ public static int getNavigationBarHeight(Context context) { int resourceId = context.getResources().getIdentifier("navigation_bar_height", "dimen", "android"); return context.getResources().getDimensionPixelSize(resourceId); }
4.)貼出整體java代碼實現方式
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); //設置狀態欄顏色 window.setStatusBarColor(color); //設置導航欄顏色 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) { //透明狀態欄 window.addFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS); //透明導航欄 window.addFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_NAVIGATION); //設置contentview為fitsSystemWindows ViewGroup contentView = (ViewGroup) findViewById(android.R.id.content); View childAt = contentView.getChildAt(0); if (childAt != null) { childAt.setFitsSystemWindows(true); } //給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以后可以對狀態欄文字顏色和圖標進行修改 getWindow().getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN | View.SYSTEM_UI_FLAG_LIGHT_STATUS_BAR); } }
