<span style="font-family: Arial, Helvetica, sans-serif; background-color: rgb(255, 255, 255);">又是幾天沒有更新部落格了，前幾天搞了一下畢業設計，今天有點時間和大家分享下gridView橫著滑動的實現。我正在一點點的進步，如果現在有什麼做的不好的地方，歡迎批評指正。</span>

首先，還是先來點效果圖看看效果。因為我不知道怎麼把視訊放上來，所以貼幾張圖，把圖連貫起來看。

mainActivity程式碼：

import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.util.DisplayMetrics;
import android.widget.GridView;
import android.widget.HorizontalScrollView;
import android.widget.LinearLayout;

import com.android.volley.RequestQueue;

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

public class MainActivity extends AppCompatActivity {
    GridView gridView;
    GridViewAdapter adapter;
    RequestQueue mRequestQueue;
    //橫屏滑動的gridview
    HorizontalScrollView horizontalScrollView;
    DisplayMetrics dm;
    private int NUM = 2; // 每行顯示個
    private int LIEWIDTH;//每列寬度
    private int LIE=4 ;//列數
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        gridView = (GridView)findViewById(R.id.gridview);
        horizontalScrollView = (HorizontalScrollView) findViewById(R.id.scrollView);
        //horizontalScrollView.setHorizontalScrollBarEnabled(false);// 隱藏滾動條

        //推薦商品
        getScreenDen();
        LIEWIDTH = dm.widthPixels / NUM;
        setValue();
        adapter=new GridViewAdapter(this,LIE);
    }
    private void setValue() {
        adapter= new GridViewAdapter(this,LIE);
        //載入資料
        List<DrugListInform> listData = new ArrayList<DrugListInform>();
        for (int i = 0; i < 4; i++) {
            DrugListInform drugList = new DrugListInform();
            drugList.setDrugName("測試"+i+"次");
            listData.add(drugList);
        }
        adapter.setListData(listData);
        gridView.setAdapter(adapter);

        LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(adapter.getCount() * LIEWIDTH,
                LinearLayout.LayoutParams.WRAP_CONTENT);
        gridView.setLayoutParams(params);
        gridView.setColumnWidth(dm.widthPixels /NUM);
        gridView.setStretchMode(GridView.NO_STRETCH);
        int count = adapter.getCount();
        gridView.setNumColumns(count);
    }

    private void getScreenDen() {
        dm = new DisplayMetrics();
        this.getWindowManager().getDefaultDisplay().getMetrics(dm);
    }
}

druglist_item可以換成自己需要的佈局。只要mainActivity中主體部分完善。
