首先先寫一個自定義的類繼承viewgroup，程式碼如下

package com.demo.com.jd_zhang.ui.customview;

import android.content.Context;
import android.util.AttributeSet;
import android.util.Log;
import android.view.View;
import android.view.ViewGroup;

import java.util.ArrayList;
import java.util.List;

        setMeasuredDimension(

    /**
     * 所有childView的位置的佈局

    @Override

        int lineHeight = 0;

        List<View> lineViews = new ArrayList<View>();
        int left = 0;
        int top = 0;

        int lineNums = mAllViews.size();
        for (int i = 0; i < lineNums; i++) {

            lineViews = mAllViews.get(i);

            lineHeight = mLineHeight.get(i);

    @Override

然後在activity裡引用

 private ArrayList<String> names;

        setTwoFlowLayout();

    }

        names = new ArrayList<String>();
        names.add("筆記本");
        names.add("空氣進化器");
        names.add("空調");
        names.add("電腦");
        names.add("華為");
        names.add("小米");
        names.add("機械誡命");
        names.add("vivo");
        //為佈局新增內容
        for (int i = 0; i < names.size(); i++) {
            addTextView(names.get(i));
        }

    }

    /**
     * 動態添加布局
     *
     * @param str
     */
    private void addTextView(String str) {
        TextView child = new TextView(this);
        ViewGroup.MarginLayoutParams params = new ViewGroup.MarginLayoutParams(ViewGroup.MarginLayoutParams.WRAP_CONTENT, ViewGroup.MarginLayoutParams.WRAP_CONTENT);
        params.setMargins(5, 5, 5, 5);
        child.setLayoutParams(params);
        child.setBackgroundResource(R.drawable.flag);
        child.setText(str);
        child.setTextColor(Color.WHITE);
        initEvents(child);//監聽
        myFlowLayout.addView(child);
    }

    //    /**
    //     * 為每個view 新增點選事件
    //     */
    private void initEvents(final TextView tv) {
        tv.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                Toast.makeText(SearchActivity.this, tv.getText().toString(), Toast.LENGTH_SHORT).show();
                Intent intent2 = new Intent(SearchActivity.this, ProductDetailsActivity.class);
                intent2.putExtra("name", tv.getText().toString());
                startActivity(intent2);
            }
        });
    }
