本文實例為大家分享了Android GridView實現橫向列表水平滾動的具體代碼，供大家參考，具體內容如下
有時候根據項目需要，使用可橫向滑動的GridView。僅以該文記錄一下，畢竟沒什么技術含量。
1.主界面布局代碼：activity_main.xml。設置android:numColumns=”auto_fit”是因為可以不定項的添加子項。
<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="fill_parent" android:orientation="vertical"> <HorizontalScrollView android:layout_width="fill_parent" android:layout_height="wrap_content"> <LinearLayout android:layout_width="wrap_content" android:layout_height="fill_parent"> <view.gridviewdemo.AblGridView android:id="@+id/id_gridview_home" android:layout_width="fill_parent" android:layout_height="fill_parent" android:gravity="center" android:numColumns="auto_fit" android:scrollbars="none" android:stretchMode="spacingWidthUniform"/> </LinearLayout> </HorizontalScrollView></LinearLayout>
2.主界面GridView列表子項布局文件：home_gridview_item.xml
<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_gravity="center" android:layout_margin="0dp" android:background="#ffffff" android:orientation="vertical"> <ImageView android:id="@+id/id_iv_item" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_gravity="center_horizontal" android:layout_marginTop="10dp" android:gravity="center" /> <TextView android:id="@+id/id_tv_item" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_gravity="center_horizontal" android:layout_marginTop="5dp" android:gravity="center" android:paddingBottom="10dp" android:text="標題文字" android:textSize="12sp" /></LinearLayout>
3.java實現代碼：MainActivity.java
import android.support.v7.app.AppCompatActivity;import android.os.Bundle;import android.util.DisplayMetrics;import android.widget.GridView;import android.widget.LinearLayout;public class MainActivity extends AppCompatActivity { AblGridView id_gridview_home; private int[] imgs = {R.mipmap.index1_nav_xc, R.mipmap.index1_nav_xc, R.mipmap.index1_nav_xc, R.mipmap.index1_nav_xc, R.mipmap.index1_nav_xc}; private String[] titles = new String[]{"子項1", "子項2","子項3","子項4", "子項5"}; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); id_gridview_home= (AblGridView) findViewById(R.id.id_gridview_home); setGridView(); } /**設置GirdView參數，綁定數據*/ private void setGridView() { int size = imgs.length; int length = 100; DisplayMetrics dm = new DisplayMetrics(); getWindowManager().getDefaultDisplay().getMetrics(dm); float density = dm.density; int gridviewWidth = (int) (size * (length + 4) * density); int itemWidth = (int) (length * density); LinearLayout.LayoutParams params = new LinearLayout.LayoutParams( gridviewWidth, LinearLayout.LayoutParams.FILL_PARENT); id_gridview_home.setLayoutParams(params); // 設置GirdView布局參數,橫向布局的關鍵 id_gridview_home.setColumnWidth(itemWidth); // 設置列表項寬 id_gridview_home.setHorizontalSpacing(5); // 設置列表項水平間距 id_gridview_home.setStretchMode(GridView.NO_STRETCH); id_gridview_home.setNumColumns(size); // 設置列數量=列表集合數 AblGridViewBaseAdapter adapter = new AblGridViewBaseAdapter(this,imgs,titles); id_gridview_home.setAdapter(adapter); }}4.自定義控件：AblGridView
import android.content.Context;import android.util.AttributeSet;import android.widget.GridView;/** * 繼承GridView控件，為了更友好的顯示 * 解決在scrollview中只顯示第一行數據的問題 */public class AblGridView extends GridView { public AblGridView(Context context, AttributeSet attrs) { super(context, attrs); } public AblGridView(Context context) { super(context); } public AblGridView(Context context, AttributeSet attrs, int defStyle) { super(context, attrs, defStyle); } @Override public void onMeasure(int widthMeasureSpec, int heightMeasureSpec) { int expandSpec = MeasureSpec.makeMeasureSpec(Integer.MAX_VALUE >> 2, MeasureSpec.AT_MOST); super.onMeasure(widthMeasureSpec, expandSpec); }}5.重寫適配器：AblGridViewBaseAdapter
import android.content.Context;import android.util.SparseArray;import android.view.LayoutInflater;import android.view.View;import android.view.ViewGroup;import android.widget.BaseAdapter;import android.widget.ImageView;import android.widget.TextView;/** * 重寫適配器 */public class AblGridViewBaseAdapter extends BaseAdapter { private Context mContext; private String[] Title;//顯示標題數組 private int[] Imgs;//顯示圖標數組 public AblGridViewBaseAdapter(Context mContext,int[] imgs ,String[] titles) { super(); this.mContext = mContext; Imgs = imgs; } @Override public int getCount() { return Title.length; } @Override public Object getItem(int position) { return position; } @Override public long getItemId(int position) { return position; } @Override public View getView(int position, View convertView, ViewGroup parent) { convertView = loadHomeHyOrYs(position, convertView, parent); return convertView; } /** * 加載會員或醫生的功能列表 */ public View loadHomeHyOrYs(int position, View convertView, ViewGroup parent) { if (convertView == null) { convertView = LayoutInflater.from(mContext).inflate( R.layout.home_gridview_item, parent, false); } TextView tv = get(convertView, R.id.id_tv_item); ImageView iv = get(convertView, R.id.id_iv_item); iv.setBackgroundResource(Imgs[position]); tv.setText(Title[position]); return convertView; } public <T extends View> T get(View view, int id) { SparseArray<View> viewHolder = (SparseArray<View>) view.getTag(); if (viewHolder == null) { viewHolder = new SparseArray<View>(); view.setTag(viewHolder); } View childView = viewHolder.get(id); if (childView == null) { childView = view.findViewById(id); viewHolder.put(id, childView); } return (T) childView; }}以上就是本文的全部內容，希望對大家的學習有所幫助，也希望大家多多支持VEVB武林網。
