动态分类搜索

效果图：

public class MainActivity extends AppCompatActivity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
   final  AssortSearchView asv = (AssortSearchView) findViewById(R.id.assort_view);
    /*执行搜索*/
    asv.getSearchBar().setOnEditorActionListener(new TextView.OnEditorActionListener() {
        @Override
        public boolean onEditorAction(TextView v, int actionId, KeyEvent event) {
            if (actionId == EditorInfo.IME_ACTION_SEARCH) {
                /*替换成自己网络请求后封装结果*/
                test(asv);
                return true;
            }
            return false;
        }
    });
    /*清空搜索*/
    asv.getSearchBar().setTextWatcher(new TextWatcher() {
        @Override
        public void beforeTextChanged(CharSequence s, int start, int count, int after) {

        }

        @Override
        public void onTextChanged(CharSequence s, int start, int before, int count) {
            if(TextUtils.isEmpty(s)){
                asv.clear();
            }
        }

        @Override
        public void afterTextChanged(Editable s) {

        }
    });

}

/**
 * 模拟请求后封装的数据
 * @param asv
 */
public void test(AssortSearchView asv){
    Category category = new Category("一级分类");
    category.add("制造业");
    category.add("销售业");
    category.add("服务业");
    category.add("IT业");
    Category category2 = new Category("二级分类");
    category2.add("制造业");
    category2.add("销售业");
    category2.add("服务业");
    category2.add("IT业");
    Category category3 = new Category("三级分类");
    category3.add("制造业");
    category3.add("销售业");
    category3.add("服务业");
    category3.add("IT业");
    Category category4 = new Category("四级分类");
    category4.add("制造业");
    category4.add("销售业");
    category4.add("服务业");
    category4.add("IT业");


    asv.addCategory(category);
    asv.addCategory(category2);
    asv.addCategory(category3);
    asv.addCategory(category4);
}

AssortSearchView.java类的实现

private int columnCount = 3;

@TargetApi(Build.VERSION_CODES.JELLY_BEAN_MR1)
public void addCategory(Category category) {
    final View item = inflate(getContext(), R.layout.category_item, null);
    final LinearLayout tagsContainer = (LinearLayout) item.findViewById(R.id.tags_container);
    final TextView title = (TextView) item.findViewById(R.id.category_title);
    title.setText(category.getCategoryId());
    List<String> tags = category.getTags();

    int size = tags.size();
    int rowCount = tags.size() / columnCount + 1;
    int tagNum = 0;
    for (int rowIndex = 0; rowIndex < rowCount; rowIndex++) {
        LinearLayout row = new LinearLayout(getContext());
        row.setPadding(6, 0, 6, 20);
        //row.setGravity(Gravity.CENTER);
        /*每行标签个数*/
        tagNum = size - rowIndex * columnCount > columnCount ? columnCount : size - rowIndex * columnCount;
        for (int col = 0; col < tagNum; col++) {
            row.addView(generateTagButton(tags.get(rowIndex * columnCount + col)));
        }
        tagsContainer.addView(row);
    }

    mParent.addView(item);
}

/**
 * 重新搜索时，需要清楚之前的搜索结果
 */
public void clear() {
    mParent.removeViews(2, mParent.getChildCount() - 2);
}

private Button generateTagButton(String tag) {
    final SelectableButton button = new SelectableButton(getContext());
    button.setText(tag);
    /*这里宽高要做适配*/
    LinearLayout.LayoutParams lp = new LinearLayout.LayoutParams(300, 120);
    lp.leftMargin = 20;
    lp.rightMargin = 20;
    button.setLayoutParams(lp);
    /*如果需要记录选中的标签*/
   /* button.setOnSelectedListener(new SelectableButton.SelectListener() {
        @Override
        public void onSelected() {
            //TODO 放到选中的集合
        }

        @Override
        public void onUnSelected() {
            //TODO 从选中的集合中移除
        }
    });*/
    return button;
}

原理很简单，注释有比较清楚的描述。

使用

Add it in your root build.gradle at the end of repositories:

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

Step 2. Add the dependency

dependencies {
        compile '.liujingsong:AssortedSearch:83c0839b04'
}
