3.Android高仿網易云音樂-首頁復雜發現界面布局和功能/RecyclerView復雜布局-有解無憂

0.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；然后是發現界面推薦單曲，點擊單曲就是直接進入播放界面；最后是全域播放控制條上點擊播放串列按鈕顯示的播放串列彈窗，

1.整體分析

整體使用RecycerView實作，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，還有最后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，主要是首頁要實作自定義順序功能，更方便管理，

2.輪播圖

2.1 布局

    android:layout_height="wrap_content"
    android:layout_margin="@dimen/padding_outer">

    <com.youth.banner.Banner
        android:id="@+id/banner"
        android:layout_
        android:layout_height="0dp"

</androidx.constraintlayout.widget.ConstraintLayout>

//banner
BannerData data = https://www.cnblogs.com/woblog/archive/2022/07/24/(BannerData) d;

Banner bannerView = holder.getView(R.id.banner);

    @Override
    public void onBindView(BannerImageHolder holder, Ad data, int position, int size) {
        ImageUtil.show(getContext(), (ImageView) holder.itemView, data.getIcon());
    }
};

bannerView.setAdapter(bannerImageAdapter);

bannerView.setOnBannerListener(onBannerListener);

bannerView.setBannerRound(DensityUtil.dip2px(getContext(), 10));

//添加生命周期觀察者
bannerView.addBannerLifecycleObserver(fragment);

bannerView.setIndicator(new CircleIndicator(getContext()));

6.迷你控制條

他是一個自定義Fragment，哪里要顯示就放到哪里就行了，

7.播放串列彈窗

 */

    ...

            @Override
            public void onClick(View v) {
                //關閉對話框
                dismiss();

                //洗掉全部音樂
                getMusicListManager().deleteAll();
            }
        });

        //item中子控制元件點擊
        //洗掉按鈕點擊
        adapter.addChildClickViewIds(R.id.delete);

        adapter.setOnItemChildClickListener(new OnItemChildClickListener() {
            @Override
            public void onItemChildClick(BaseQuickAdapter adapter, View view, int position) {
                //由于這里只有一個按鈕點擊
                //所以可以不判斷
                if (R.id.delete == view.getId()) {
                    //洗掉按鈕點擊
                    removeItem(position);
                }
            }
        });

        //回圈模式點擊
        binding.loopModel.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                //更改回圈模式
                getMusicListManager().changeLoopModel();

                //顯示回圈模式
                showLoopModel();

            }
        });

        //設定item點擊事件
        adapter.setOnItemClickListener(new OnItemClickListener() {

            public void onItemClick(BaseQuickAdapter adapter, View view, int position) {
                //關閉dialog
                //可以根據具體的業務邏輯來決定是否關閉
                dismiss();

                //播放點擊的這首音樂
                getMusicListManager().play(getMusicListManager().getDatum().get(position));
            }
        });

    }

    private void removeItem(int position) {
        adapter.removeAt(position);

        //從串列管理器中洗掉
        getMusicListManager().delete(position);

        showCount();
    }

    /**
     * 顯示回圈模式
     */
    private void showLoopModel() {
        PlayListUtil.showLoopModel(getMusicListManager().getLoopModel(), binding.loopModel);
    }

    private void showCount() {
        binding.count.setText(String.format("(%d)", getMusicListManager().getDatum().size()));
    }
}
