在大佬MarqueeViewLibrary框架的基础上实现控件的各项参数动态配置;
原文地址:
https://gitcode.net/mirrors/gongwen/MarqueeViewLibrary
实现后效果图:
配置参数 动态替换下面的值即可
Boolean isPlayAnim = true;//是否滚动
int width = 600;//控件宽度dp
int heigh = 80;//控件高度dp
int margin_left = 5;//左边距 dp
int margin_right = 0;//右边距 dp
int margin_top = 5;//上边距 dp
int margin_bottom = 0;//下边距 dp
String backgroundColor = "#cccccc";//控件背景色
int fontSize = 14;//字体大小dp
String textColor = "#000000";//字体颜色
int scrollSpeed = 4000;//翻页速度 毫秒
int scrollDirection = 4;//滚动方向:1上2下3左4右 其他默认左;
int animSpeed = 2000;//动画持续时间 毫秒
boolean isSingleLine = true;//是否单行
int textAlineType = 1;//文字居中方式:1居中,2横向居中3纵向居中 默认1
//设置数据源
final List<String> datas = Arrays.asList("《赋得古原草送别》", "离离原上草，一岁一枯荣。", "野火烧不尽，春风吹又生。", "远芳侵古道，晴翠接荒城。",
"又送王孙去，萋萋满别情。", "文字显示不下时，系统的处理方式(可选：none，start，middle，end)");
配置控制
//本地父布局
RelativeLayout rl_main_layout = findViewById(R.id.rl_main_layout);
int widthPx = MyUtils.px2dip(this, width);
int heighPx = MyUtils.px2dip(this, heigh);

MyUtils.dip2px(this, margin_right), MyUtils.dip2px(this, margin_bottom));
marqueeView.setLayoutParams(layoutParams);//设置宽高及margin
rl_main_layout.setBackgroundColor(Color.parseColor(backgroundColor));//设置背景色
rl_main_layout.addView(marqueeView);

}

}
