本文实例为大家分享了Android使用Gridview单行横向滚动显示的具体代码，供大家参考，具体内容如下
要想实现滚动显示，layout布局里必须要使用HorizontalScrollView，才能实现横向滑动，但HorizontalScrollView标签里要嵌套一个LinearLayout布局
activity_main.xml,如下:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".MainActivity"
android:orientation="vertical"
android:weightSum="2"
<HorizontalScrollView
android:id="@+id/horizontal_scrollview"
android:layout_height="0dp"
android:layout_width="fill_parent"
android:layout_weight="1"
android:layout_gravity="center"
android:background="@android:color/darker_gray"
android:scrollbars="none"
<LinearLayout
android:layout_height="match_parent"
android:layout_width="match_parent"
android:orientation="horizontal"
<GridView
android:id="@+id/test_gridview"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="center"/
</LinearLayout
</HorizontalScrollView
</LinearLayout 复制
gridview中的item的布局如下：
<?xml version="1.0" encoding="utf-8"?
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="80dp"
android:layout_height="match_parent"
android:orientation="vertical"
<ImageView
android:id="@+id/item_img"
android:layout_width="60dp"
android:layout_height="60dp"
android:layout_gravity="center_horizontal"
android:scaleType="fitXY"
android:background="#00000000"/
<TextView
android:id="@+id/item_text"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="center_horizontal"
android:textSize="20dp"
android:text="233"
android:textColor="@android:color/white"/
</LinearLayout 复制
实现类如下：
package com.example.scrollgridview;
import android.os.Bundle;
import android.app.Activity;
import android.content.Context;
import android.util.DisplayMetrics;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.AdapterView;
import android.widget.AdapterView.OnItemClickListener;
import android.widget.BaseAdapter;
import android.widget.GridView;
import android.widget.ImageView;
import android.widget.LinearLayout;
import android.widget.TextView;
public class MainActivity extends Activity {
private GridView gridview;
private int imgs[]={R.drawable.remote_tv_0,
R.drawable.remote_tv_1,R.drawable.remote_tv_2,
R.drawable.remote_tv_3,R.drawable.remote_tv_4,
R.drawable.remote_tv_5,R.drawable.remote_tv_6,
R.drawable.remote_tv_7,R.drawable.remote_tv_8,
R.drawable.remote_tv_9};
private GridviewAdapter adapter;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
gridview = (GridView)findViewById(R.id.test_gridview);
adapter = new GridviewAdapter();
DisplayMetrics dm = new DisplayMetrics();
getWindowManager().getDefaultDisplay().getMetrics(dm);
float density = dm.density;
int size = imgs.length;//要显示数据的个数
//gridview的layout_widht,要比每个item的宽度多出2个像素，解决不能完全显示item的问题
int allWidth = (int) (82 * size * density);
//int allWidth = (int) ((width / 3 ) * size + (size-1)*3);//也可以这样使用，item的总的width加上horizontalspacing
int itemWidth = (int) (80 * density);//每个item宽度
LinearLayout.LayoutParams params = new
LinearLayout.LayoutParams(allWidth,LinearLayout.LayoutParams.MATCH_PARENT);
gridview.setLayoutParams(params);
gridview.setColumnWidth(itemWidth);
gridview.setHorizontalSpacing(3);
gridview.setStretchMode(GridView.NO_STRETCH);
gridview.setNumColumns(size);
gridview.setAdapter(adapter);
adapter.setindex(0);
adapter.notifyDataSetChanged();
gridview.setOnItemClickListener(new OnItemClickListener() {
@Override
public void onItemClick(AdapterView<? parent, View view,
int position, long id) {
// TODO Auto-generated method stub
adapter.setindex(position);
adapter.notifyDataSetChanged();
}
});
}
class GridviewAdapter extends BaseAdapter{
private int index = 0;
@Override
public int getCount() {
// TODO Auto-generated method stub
return imgs.length;
}
@Override
public Object getItem(int position) {
// TODO Auto-generated method stub
return imgs[position];
}
@Override
public long getItemId(int position) {
// TODO Auto-generated method stub
return position;
}
public void setindex(int index){
this.index = index;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
// TODO Auto-generated method stub
LayoutInflater mInflater = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE);
ViewHolder viewHolder;
if (convertView == null) {
convertView = mInflater.inflate(R.layout.gridview_itme, null);
viewHolder = new ViewHolder();
viewHolder.img = (ImageView)convertView.findViewById(R.id.item_img);
viewHolder.text = (TextView)convertView.findViewById(R.id.item_text);
convertView.setTag(viewHolder);
}else{
viewHolder = (ViewHolder)convertView.getTag();
}
if(this.index == position){
convertView.setBackgroundResource(R.drawable.list_item_bg_focus);
}
else{
convertView.setBackgroundResource(R.drawable.list_item_bg);
}
viewHolder.img.setImageResource(imgs[position]);
viewHolder.text.setText(position+"");
return convertView;
}
class ViewHolder{
ImageView img;
TextView text;
}
}
} 复制
