安卓GridView（自定義適配器）

先貼布局：就放了一個GridView

<?xml version="1.0" encoding="utf-8"?>
<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="custom.community.com.generic_deom.MainActivity">

 <GridView
     android:id="@+id/gridview"
     android:layout_width="fill_parent"
     android:layout_height="wrap_content"

     android:listSelector="@null"
     android:horizontalSpacing="0.5dp"
     android:verticalSpacing="0.5dp"
     android:background="#c9c9c9"
     android:numColumns="3"
     android:scrollbars="none"
     android:stretchMode="columnWidth"

     />

</LinearLayout>

代碼：

public class MainActivity extends AppCompatActivity {
    private GridView gridview;

    GridViewSim myGridView;
    LayoutInflater  inflater;
    //定義兩個數組，放圖片和文字
   private String text[]={"text1","text2","text3","text4","text5","text6","text7","text8","text9"};
   private int img_grid[] ={R.drawable.a,R.drawable.b,R.drawable.c,
           R.drawable.d,R.drawable.e,R.drawable.f,R.drawable.g,R.drawable.h,R.drawable.i};
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        gridview=(GridView)findViewById(R.id.gridview);

        myGridView=new GridViewSim(this,text,img_grid);
        gridview.setAdapter(myGridView);

        inflater= LayoutInflater.from(this);
    }


class GridViewSim extends BaseAdapter{
    private Context context=null;
    private String data[]=null;
    private int imgId[]=null;


    private class Holder{

        ImageView item_img;
        TextView item_tex;

        public ImageView getItem_img() {
            return item_img;
        }

        public void setItem_img(ImageView item_img) {
            this.item_img = item_img;
        }

        public TextView getItem_tex() {
            return item_tex;
        }

        public void setItem_tex(TextView item_tex) {
            this.item_tex = item_tex;
        }




    }
    //構造方法
    public GridViewSim(Context context, String[] data, int[] imgId) {
        this.context = context;
        this.data = data;
        this.imgId = imgId;
    }


    @Override
    public int getCount() {


        return data.length;

    }

    @Override
    public Object getItem(int position) {
        return position;
    }

    @Override
    public long getItemId(int position) {
        return position;
    }

    @Override
    public View getView(int position, View view, ViewGroup viewGroup) {
        Holder holder;
          if(view==null){
            view=inflater.inflate(R.layout.item_listview,null);
             holder=new Holder();
              holder.item_img=(ImageView)view.findViewById(R.id.item_img);
              holder.item_tex=(TextView)view.findViewById(R.id.item_text);
              view.setTag(holder);
          }else{
              holder=(Holder) view.getTag();
          }
        holder.item_tex.setText(data[position]);
        holder.item_img.setImageResource(imgId[position]);

        return view;
    }
}


}

另外是item的佈局

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="#ffffff"
    android:gravity="center"
    android:padding="4dp"
    >
<ImageView
    android:id="@+id/item_img"
    android:layout_width="64dp"
    android:layout_height="64dp"


    />
    <TextView
        android:id="@+id/item_text"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"

        />
</LinearLayout>

如果要限制GridView滑動，可以自定義一個Gridview重寫dispatchTouchEvent方法

 */
public class MyGridview extends GridView {
    public MyGridview(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    public MyGridview(Context context) {
        super(context);
    }

    public MyGridview(Context context, AttributeSet attrs, int defStyleAttr) {
        super(context, attrs, defStyleAttr);
    }
    //通過重寫dispatchTouchEvent方法來禁止滑動
    @Override
    public boolean dispatchTouchEvent(MotionEvent ev) {
        if(ev.getAction() == MotionEvent.ACTION_MOVE){
            return true;//禁止Gridview進行滑動
        }
        return super.dispatchTouchEvent(ev);

    }
}

ps:在xml佈局中引用時記得寫上自己的定義的gridview全路徑名稱
