android -------- 流式布局,支持单选、多选等

最近开发中有流式标签这个功能,网上学了下,来分享一下

Android 流式布局,支持单选、多选等,适合用于产品标签等。

效果图:

android  -------- 流式布局,支持单选、多选等

用法:

dependencies {
compile 'com.hyman:flowlayout-lib:1.1.2'
}

布局:

   <!--max_select:-1为不限制选择数量,>=1的数字为控制选择tag的数量-->
<com.zhy.view.flowlayout.TagFlowLayout
android:id="@+id/id_flowlayout"
zhy:max_select="-1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:padding="20dp">
</com.zhy.view.flowlayout.TagFlowLayout>

代码:

public class FlowlayoutActivity extends AppCompatActivity {

    TagFlowLayout tagFlowLayout;
private List<String> list;
private LayoutInflater layoutInflater; @Override
protected void onCreate(@Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.flowlayout_activity); list= new ArrayList<>();
list.add("新闻");
list.add("美食");
list.add("体育");
list.add("生活号");
list.add("预留");
list.add("娱乐");
list.add("杭州市");
list.add("太行");
list.add("舞蹈");
list.add("直播");
list.add("新闻");
list.add("美食");
list.add("体育");
list.add("生活号");
list.add("预留");
list.add("娱乐");
list.add("杭州市");
list.add("太行");
list.add("舞蹈");
list.add("直播");
initView();
} private void initView(){
layoutInflater = LayoutInflater.from(this);
tagFlowLayout = findViewById(R.id.id_flowlayout); tagFlowLayout.setAdapter(new TagAdapter<String>(list)
{
@Override
public View getView(FlowLayout parent, int position, String s)
{
TextView tv = (TextView) layoutInflater.inflate(R.layout.flowlayout_item_tv,
tagFlowLayout, false);
tv.setText(s);
return tv;
}
}); tagFlowLayout.setOnTagClickListener(new TagFlowLayout.OnTagClickListener()
{
@Override
public boolean onTagClick(View view, int position, FlowLayout parent)
{
//得到点击的值
Toast.makeText(getApplicationContext(), list.get(position), Toast.LENGTH_SHORT).show();
return true;
}
}); tagFlowLayout.setOnSelectListener(new TagFlowLayout.OnSelectListener() {
@Override
public void onSelected(Set<Integer> selectPosSet) {
Log.i("得到下标的集合",selectPosSet.toString());
//得到下标的集合
//Toast.makeText(getApplicationContext(), selectPosSet.toString()+"s", Toast.LENGTH_SHORT).show();
}
}); /*//预先设置选中
mAdapter.setSelectedList(1,3,5,7,8,9);
//获得所有选中的pos集合
flowLayout.getSelectedList();*/
}
}
