【鼠】安卓学习杂记（十）——Android开源下拉框Nice Spinner的使用

一、效果图

二、GitHub网址

https://github.com/arcadefire/nice-spinner

三、使用方法

1、添加依赖

allprojects {
    repositories {
        ...
        maven { url "https://jitpack.io" }
    }
}

dependencies {
    implementation 'com.github.arcadefire:nice-spinner:1.3.4'
}

2、XML中实现

3、Java中实现

 NiceSpinner niceSpinner = (NiceSpinner) findViewById(R.id.nice_spinner);
 List dataset = new LinkedList<>(Arrays.asList("菜单一", "菜单二", "菜单三", "菜单四", "菜单五"));
 niceSpinner.attachDataSource(dataset);

4、设置菜单被选中的监听事件

niceSpinner.addOnItemClickListener(new AdapterView.OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView parent, View view, int position, long id) {
                switch (position){
                    case 0:
                        Toast.makeText(MainActivity.this, "已选定菜单一", Toast.LENGTH_SHORT).show();
                        break;
                    case 1:
                        Toast.makeText(MainActivity.this, "已选定菜单二", Toast.LENGTH_SHORT).show();
                        break;
                    case 2:
                        Toast.makeText(MainActivity.this, "已选定菜单三", Toast.LENGTH_SHORT).show();
                        break;
                    case 3:
                        Toast.makeText(MainActivity.this, "已选定菜单四", Toast.LENGTH_SHORT).show();
                        break;
                    case 4:
                        Toast.makeText(MainActivity.this, "已选定菜单五", Toast.LENGTH_SHORT).show();
                        break;
                    default:
                        Toast.makeText(MainActivity.this, "无选定任何菜单", Toast.LENGTH_SHORT).show();
                }
            }
        });
