Android實現網易雲音樂高仿版流程

效果圖

效果圖依次為發現界面頂部，包含首頁輪播圖，水平滾動的按鈕，推薦歌單；然後是發現界面推薦單曲，點擊單曲就是直接進入播放界面；最後是全局播放控制條上點擊播放列表按鈕顯示的播放列表彈窗。

整體分析

整體使用RecycerView實現，每個不同的塊是一個Item，例如：輪播圖是一個Item，按鈕也是，推薦歌單和下面的歌單是，推薦單曲，還有最後的自定義首頁那塊也是一樣。

提示：之所以把推薦歌單下面的歌單和推薦歌單標題放一個Item，主要是首頁要實現自定義順序功能，更方便管理。

輪播圖

迷你控制條

他是一個自定義Fragment，哪裡要顯示就放到哪裡就行瞭。

播放列表彈窗

                dismiss();
                //刪除全部音樂
                getMusicListManager().deleteAll();
            }
        });

            public void onItemChildClick(BaseQuickAdapter adapter, View view, int position) {
                //由於這裡隻有一個按鈕點擊
                //所以可以不判斷
                if (R.id.delete == view.getId()) {
