Filter

这是一个实现安卓筛选框的插件，下面是演示效果：

大家可以通过以下方式引用： 添加Filter到你的项目

      implementation 'com.github.zhujiang521:Filter:1.0.0'
      maven { url 'https://jitpack.io' }

下面是使用方法： public class MainActivity extends AppCompatActivity {

private TextView one;
//筛选框控件
private FlowPopWindow flowPopWindow;
//筛选框数据
private List<FiltrateBean> dictList = new ArrayList<>();

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    initParam();
    initView();
}

private void initView() {
    one = findViewById(R.id.one);
    one.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            flowPopWindow = new FlowPopWindow(MainActivity.this, dictList);
            flowPopWindow.showAsDropDown(one);
            flowPopWindow.setOnConfirmClickListener(new FlowPopWindow.OnConfirmClickListener() {
                @Override
                public void onConfirmClick() {
                    StringBuilder sb = new StringBuilder();
                    for (FiltrateBean fb : dictList) {
                        List<FiltrateBean.Children> cdList = fb.getChildren();
                        for (int x = 0; x < cdList.size(); x++) {
                            FiltrateBean.Children children = cdList.get(x);
                            if (children.isSelected())
                                sb.append(fb.getTypeName() + ":" + children.getValue() + "；");
                        }
                    }
                    if (!TextUtils.isEmpty(sb.toString()))
                        Toast.makeText(MainActivity.this, "111"+sb.toString(), Toast.LENGTH_LONG).show();
                }
            });

        }
    });
}


//这些是假数据，真实项目中直接接口获取添加进来，FiltrateBean对象可根据自己需求更改
private void initParam() {
    String[] sexs = {"男", "女"};
    String[] colors = {"红色", "浅黄色", "橙子色", "鲜绿色", "青色", "天蓝色", "紫色", "黑曜石色", "白色", "五颜六色"};
    String[] company = {"阿里巴巴集团", "腾讯集团", "华为技术服务有限公司", "小米", "www.xiaomi.com"};

    FiltrateBean fb1 = new FiltrateBean();
    fb1.setTypeName("性别");
    List<FiltrateBean.Children> childrenList = new ArrayList<>();
    for (String sex : sexs) {
        FiltrateBean.Children cd = new FiltrateBean.Children();
        cd.setValue(sex);
        childrenList.add(cd);
    }
    fb1.setChildren(childrenList);

    FiltrateBean fb2 = new FiltrateBean();
    fb2.setTypeName("颜色");
    List<FiltrateBean.Children> childrenList2 = new ArrayList<>();
    for (String color : colors) {
        FiltrateBean.Children cd = new FiltrateBean.Children();
        cd.setValue(color);
        childrenList2.add(cd);
    }
    fb2.setChildren(childrenList2);

    FiltrateBean fb3 = new FiltrateBean();
    fb3.setTypeName("企业");
    List<FiltrateBean.Children> childrenList3 = new ArrayList<>();
    for (String s : company) {
        FiltrateBean.Children cd = new FiltrateBean.Children();
        cd.setValue(s);
        childrenList3.add(cd);
    }
    fb3.setChildren(childrenList3);

    dictList.add(fb1);
    dictList.add(fb2);
    dictList.add(fb3);
}

}
