实现一个"综合"按钮类

一个item有很多按钮，可以实现一个按钮类，包含这些按钮，通过init(int type)来初始化特定的按钮。

 

图2中这是用代码来实现了selector。 

 使用、初始化：

            mDelete.init(HiSingListClickView.VIEW_TYPE_DELETE);
            mCollect.init(HiSingListClickView.VIEW_TYPE_COLLECT);
            mKtv.init(HiSingListClickView.VIEW_TYPE_SING);
            mTop.init(HiSingListClickView.VIEW_TYPE_TOP);

 

全部代码：

public class HiSingListClickView extends HiSingShadowLinearLayout {

    private static final String TAG = "HiSingListClickView";
    private ImageView mIcon;
    private TextView mTitleTv;
    //K歌
    public static final int VIEW_TYPE_PLAY = 0;
    //点歌
    public static final int VIEW_TYPE_ADD = 1;
    //收藏
    public static final int VIEW_TYPE_COLLECT = 2;
    //置顶
    public static final int VIEW_TYPE_TOP = 3;
    //删除
    public static final int VIEW_TYPE_DELETE = 4;
    //分享
    public static final int VIEW_TYPE_SHARE = 5;
    //作品播放
    public static final int VIEW_TYPE_SING = 6;
    //点赞
    public static final int VIEW_TYPE_LIKE = 7;

    public HiSingListClickView(Context context) {
        super(context);
        initViews(context);
    }

    public HiSingListClickView(Context context, @Nullable AttributeSet attrs) {
        super(context, attrs);
        initViews(context);
    }

    public HiSingListClickView(Context context, @Nullable AttributeSet attrs, int defStyleAttr) {
        super(context, attrs, defStyleAttr);
        initViews(context);
    }

    private void initViews(Context context) {
        LayoutInflater.from(context).inflate(R.layout.hising_list_click_view, this);
        mIcon = findViewById(R.id.hising_click_image);
        mTitleTv = findViewById(R.id.hising_click_tv);
        setGravity(Gravity.CENTER);
        setPadding(getResources().getDimensionPixelOffset(R.dimen.dimen_22),
                0,
                getResources().getDimensionPixelOffset(R.dimen.dimen_22),
                0);
    }

    }

另外，setvisible()这样实现在工具类里使用比较方便，不用一遍一遍的写判空条件了：

HiSingViewUtil.setVisible(mTitleTv, selected);

    public static void setVisible(View view, boolean show) {
        if (view == null) {
            return;
        }
        view.setVisibility(show ? View.VISIBLE : View.GONE);
    }

 

public class HiSingViewUtil {
    /**
     * 设置文本颜色
     *
     * @param view   文本
     * @param select 是否设置遗留焦点色
     */
    public static void setTextSelectColor(TextView view, boolean select) {
        if (view != null) {
            view.setTextColor(HiSingUiUtil.getColor(select ? IDrawableService.ColorEnum.SELECTED :
                    IDrawableService.ColorEnum.TEXT_NORMAL));
        }
    }

    public static void setText(TextView view, String text) {
        if (view == null) {
            return;
        }
        view.setText(text);
    }

    public static void setVisible(View view, boolean show) {
        if (view == null) {
            return;
        }
        view.setVisibility(show ? View.VISIBLE : View.GONE);
    }

    public static void setVisible(View view, int visibility) {
        if (view == null) {
            return;
        }
        view.setVisibility(visibility);
    }

    /**
     * view获取焦点，适配触控模式点击获取焦点
     *
     * @param view 组件view
     */
    public static boolean requestFocus(View view) {
        if (view != null) {
            view.setFocusableInTouchMode(true);
            return view.requestFocus();
        }
        return false;
    }
}

试一下，一个view包含多个按钮，点击事件的响应是怎样的，按钮能否响应点击事件。 

一口吃不成胖子，在于一点一滴的积累。
