快速开发之-在项目里定义一个通用titleBar

声明

本文并非教程，而是笔记，不会对知识点一个一个的解释，当然如果能帮到小伙伴，我也会感到很欣慰，有好的意见以及方案，可以回复

目的

免除重复XML代码编写，继承Toolbar
可拓展性，其他特殊标题继承titleBar可以轻松拓展
方便全栈样式统一

知识点

Toolbar
ViewGroup

很简单 直接附上代码 只是最基础版的 根据实际项目需要修改

CommonTitleBar

public class CommonTitleBar extends Toolbar {

    private String titleName;
    private int leftButtonBackground;
    private int rightButtonBackground;

    private TextView toolbarTitle;
    private ImageButton toolbarButtonLeft;
    private ImageButton toolbarButtonRight;

        this(context, null);
    }

        this(context, attrs, 0);
    }

    public CommonTitleBar(Context context, @Nullable AttributeSet attrs, int defStyleAttr) {
        super(context, attrs, defStyleAttr);
        LayoutInflater.from(context).inflate(R.layout.common_titlebar_layout, this);
        initAttr(attrs);
        initView();
    }

    private void initAttr(AttributeSet attrs) {
        TypedArray typedArray = getContext().obtainStyledAttributes(attrs, R.styleable.CommonTitleBar);
        titleName = typedArray.getString(R.styleable.CommonTitleBar_titleName);
        leftButtonBackground = typedArray.getInt(R.styleable.CommonTitleBar_leftButtonBackground, R.mipmap.toolbar_back);
        rightButtonBackground = typedArray.getInt(R.styleable.CommonTitleBar_rightButtonBackground, 0);
    }

    }

        toolbarTitle.setText(titleName);

    }

    public void setmLeftClick(final onViewClick mLeftClick) {

            public void onClick(View v) {
                if(AntiShake.check(v.getId())){
                    mLeftClick.onViewClick();
                }
            }
        });
    }

    /**右边左边按钮点击监听 已添加防止重复点击
     * @param mRightClick
     */

                if(AntiShake.check(v.getId())){
                    mRightClick.onViewClick();
                }
            }
        });
    }


    private interface onViewClick {
        void onViewClick();
    }
}
