65 | dataList.add("数据结构"); 66 | dataList.add("算法"); 67 | dataList.add("Java"); 68 | dataList.add("多线程编程"); 69 | 70 | // 添加tag 71 | flowTagLayout.addTags(dataList); // 添加tag的列表，该方法会把之前的tags全部清空 72 | flowTagLayout.addTag("Kotlin"); // 在尾部添加一个tag 73 | flowTagLayout.addTagOfIndex(2,"自定义view"); // 在指定的位置插入tag，示例为在index为2，也就是第三个位置插入tag 74 | 75 | // 移除tag 76 | flowTagLayout.removeTag(); // 移除尾部tag 77 | flowTagLayout.removeTagOfIndex(3);
