标题栏自定义布局：

 

<com.xxx.TopBar
        android:id="@+id/top_bar"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"/>

 

private void initTopBar() {
        topBar.setTitile("帮你贷").setVisible(false).setTitleBarListener(new TopBar.BtnClickListener() {
            @Override
            public void leftClick() {
                finish();
            }

            @Override
            public void rightClick() {

            }
        });
