FlowLayout

Android 流式布局FlowLayout 实现关键字标签

效果图

使用方法

• 在项目根目录的build.gradle文件中加入如下代码

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

• 在app根目录的buil.gradle文件中加入依赖

compile 'com.github.alidili:FlowLayout:v1.5'

• 在Activity中使用，设置点击事件

public class MainActivity extends AppCompatActivity {

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

        FlowLayout flKeyword = findViewById(R.id.fl_keyword);

        // 关键字集合
        List<String> list = new ArrayList<>();
        list.add("关键词一");
        list.add("关键词二");
        list.add("关键词三");
        list.add("关键词四");
        list.add("关键词五");

        // 设置文字大小
        flKeyword.setTextSize(15);
        // 设置文字颜色
        flKeyword.setTextColor(Color.BLACK);
        // 设置文字背景
        flKeyword.setBackgroundResource(R.drawable.bg_frame);

        // 设置文字水平margin
        flKeyword.setHorizontalSpacing(15);
        // 设置文字垂直margin
        flKeyword.setVerticalSpacing(15);

        // 设置文字水平padding
        flKeyword.setTextPaddingH(15);
        // 设置文字垂直padding
        flKeyword.setTextPaddingH(8);

        // 设置UI与点击事件监听
        // 最后调用setViews方法
        flKeyword.setViews(list, new FlowLayout.OnItemClickListener() {
            @Override
            public void onItemClick(String content) {
                Toast.makeText(MainActivity.this, content, Toast.LENGTH_SHORT).show();
            }
        });

        // 增加关键字
        flKeyword.addView("关键字六", new FlowLayout.OnItemClickListener() {
            @Override
            public void onItemClick(String content) {
                Toast.makeText(MainActivity.this, content, Toast.LENGTH_SHORT).show();
            }
        });
    }
}

• 布局文件

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <com.yang.flowlayoutlibrary.FlowLayout
        android:id="@+id/fl_keyword"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_marginLeft="10dp"
        android:layout_marginRight="10dp"
        android:layout_marginTop="10dp"
        app:backgroundResource="@drawable/bg_frame"
        app:horizontalSpacing="15dp"
        app:itemColor="@color/colorAccent"
        app:itemSize="15sp"
        app:textPaddingH="15dp"
        app:textPaddingV="8dp"
        app:verticalSpacing="15dp" />

</RelativeLayout>
