Android中怎么利用Gridview實現一個圖片列表

Android中怎么利用Gridview實現一個圖片列表，針對這個問題，這篇文章詳細介紹了相對應的分析和解答，希望可以幫助更多想解決這個問題的小伙伴找到更簡單易行的方法。

1.創建一個新的項目:gridview.

2,打開 res/layout/main.xml文件,插入一下代碼:

<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"     android:orientation="vertical"     android:layout_width="fill_parent"     android:layout_height="fill_parent"     > <GridView          android:id="@+id/gridview"          android:layout_width="fill_parent"          android:layout_height="fill_parent"          android:columnWidth="90dp"          android:numColumns="auto_fit"          android:verticalSpacing="10dp"          android:horizontalSpacing="10dp"          android:stretchMode="columnWidth"          android:gravity="center"          />   </LinearLayout>

做好以后就可以在屏幕上顯示一個grid view

3.打開gridview.java首先要導入包:

package cn.gridview;  import android.widget.GridView;  import android.widget.Toast;  import android.app.Activity;  import android.os.Bundle;  import android.widget.AdapterView.OnItemClickListener;  import android.widget.AdapterView;  import android.view.View;  在onCreate添加方法:   public void onCreate(Bundle savedInstanceState) {          super.onCreate(savedInstanceState);          setContentView(R.layout.main);          GridView gridview=(GridView)findViewById(R.id.gridview);//找到main.xml中定義gridview 的id          gridview.setAdapter(new ImageAdapter(this));//調用ImageAdapter.java          gridview.setOnItemClickListener(new OnItemClickListener(){//監聽事件           public void onItemClick(AdapterView<?> parent, View view, int position, long id)            {            Toast.makeText(gridview.this, ""+position,Toast.LENGTH_SHORT).show();//顯示信息;           }          });      }  ImageAdapter.java  package cn.gridview;  import android.view.View;  import android.view.ViewGroup;  import android.widget.BaseAdapter;  import android.content.Context;  import android.widget.ImageView;  import android.widget.GridView;  public class ImageAdapter extends BaseAdapter {   private Context mContext;      public ImageAdapter(Context c)   {    mContext=c;   }   @Override   public int getCount() {    // TODO Auto-generated method stub    return mThumbIds.length;   }  @Override   public Object getItem(int position) {    // TODO Auto-generated method stub    return null;   }  @Override   public long getItemId(int position) {    // TODO Auto-generated method stub    return 0;   }   @Override   public View getView(int position, View convertView, ViewGroup parent) {    // TODO Auto-generated method stub        ImageView imageview;    if(convertView==null)    {     imageview=new ImageView(mContext);     imageview.setLayoutParams(new GridView.LayoutParams(85, 85));     imageview.setScaleType(ImageView.ScaleType.CENTER_CROP);     imageview.setPadding(8,8,8,8);   }    else    {     imageview=(ImageView) convertView;    }    imageview.setImageResource(mThumbIds[position]);    return imageview;    }  private Integer[] mThumbIds={//顯示的圖片數組     R.drawable.sample_2,R.drawable.sample_3,    R.drawable.sample_4,R.drawable.sample_5,    R.drawable.sample_6,R.drawable.sample_7,    R.drawable.sample_0,R.drawable.sample_1,    R.drawable.sample_2,R.drawable.sample_3,    R.drawable.sample_4,R.drawable.sample_5,    R.drawable.sample_6,R.drawable.sample_7,    R.drawable.sample_0,R.drawable.sample_1,    R.drawable.sample_2,R.drawable.sample_3,    R.drawable.sample_4,R.drawable.sample_5,    R.drawable.sample_6,R.drawable.sample_7,   };  }
