BottomSheetDialog的簡單使用
BottomSheetDialog bsd = new MyBottomSheetDialog(this);bsd.setContentView(R.layout.items);//布局為任意布局bsd.show();比較坑的地方是：
當我們設置bottomSheetDialog點擊后不new,而是直接show的話，然而當我們會bottomSheetDialog 展開后，我們將BottomSheetDialog劃下隱藏后， 再點擊展示BottomSheetDialog后，會發現頁面只是變暗，BottomsheetDialog未展開，這是由于之前我們劃下收縮隱藏BottomSheetDialog后，bottomSheetDialogBehavior的狀態為隱藏，再次show之后，系統未恢復bottomSheetDialogBehavior的狀態，還是隱藏，所以再次點擊后頁面只是變暗。（未能解決，暫時只能每次都new）
繼承BottomSheetDialog并重寫其PRotected void onCreate(Bundle savedInstanceState)方法
Activity mActivity; public MyBottomSheetDialog(@NonNull Context context) { super(context); mActivity = (Activity) context; }protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); int screenHeight = getScreenHeight(mActivity); int statusBarHeight = getStatusBarHeight(getContext()); int dialogHeight = screenHeight - statusBarHeight; getWindow().setLayout(ViewGroup.LayoutParams.MATCH_PARENT, dialogHeight == 0 ? ViewGroup.LayoutParams.MATCH_PARENT : dialogHeight); } private static int getScreenHeight(Activity activity) { DisplayMetrics displaymetrics = new DisplayMetrics(); activity.getWindowManager().getDefaultDisplay().getMetrics(displaymetrics); return displaymetrics.heightPixels; } private static int getStatusBarHeight(Context context) { int statusBarHeight = 0; Resources res = context.getResources(); int resourceId = res.getIdentifier("status_bar_height", "dimen", "android"); if (resourceId > 0) { statusBarHeight = res.getDimensionPixelSize(resourceId); } return statusBarHeight; }新聞熱點
