GridView（表格式布局）

用法跟listView区别不大，就是布局中多了一个属性

<GridView
android:id="@+id/gridview_photo"
android:layout_width="match_parent"
android:layout_height="match_parent"

android:numColumns="3"></GridView>     
显示3排，效果：

Mainactivity代码

public class MainActivity extends Activity {
private List<Fruit> mFruits;
private GridView gridView;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
gridView= (GridView) findViewById(R.id.gridview_photo);
       LayoutInflater inflater=getLayoutInflater();


mFruits=new ArrayList<>();
for(int i=0;i<20;i++){
mFruits.add(new Fruit("苹果",R.mipmap.apple));
mFruits.add(new Fruit("草莓",R.mipmap.berry));
mFruits.add(new Fruit("橘子",R.mipmap.orange));
        }
        GridAdapter adapter = new GridAdapter(inflater, mFruits);
gridView.setAdapter(adapter);
    }

model：Fruit代码

public class Fruit {
private String name;
private int img;
private boolean[] mManagerAllCheckedBox;



public Fruit(String name, int img) {
this.name = name;
this.img = img;

    }

public void setName(String name) {
this.name = name;
    }

public void setImg(int img) {
this.img = img;
    }

public int getImg() {
return img;
    }

public String getName() {
return name;
    }
}
自定义adapter代码

public class GridAdapter extends BaseAdapter{
private LayoutInflater mInflater;
private List<Fruit> mFruits;
private boolean[] mManagerChecBox;

public GridAdapter(LayoutInflater mInflater, List<Fruit> mFruits) {
this.mInflater = mInflater;
this.mFruits = mFruits;
mManagerChecBox=new boolean[mFruits.size()];
    }

@Override
public int getCount() {
return mFruits.size();
    }

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

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

@Override
public View getView(final int position, View convertView, ViewGroup parent) {
        Fruit fruit= mFruits.get(position);
        ViewHolder viewHolder=null;
if(convertView==null){
            viewHolder=new ViewHolder();
            convertView=mInflater.inflate(R.layout.item_grid,null);
            viewHolder.imageView= (ImageView) convertView.findViewById(R.id.imgview_grid);
            viewHolder.checkBox= (CheckBox) convertView.findViewById(R.id.checkbox_grid);
            viewHolder.imageView_back= (ImageView) convertView.findViewById(R.id.imgview_background);
            viewHolder.textView= (TextView) convertView.findViewById(R.id.textview_grid);
            convertView.setTag(viewHolder);
        }else{
            viewHolder= (ViewHolder) convertView.getTag();
        }
        viewHolder.imageView.setImageResource(fruit.getImg());
        viewHolder.textView.setText(fruit.getName());
        viewHolder.checkBox.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
@Override
public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {

mManagerChecBox[position] = isChecked;
                notifyDataSetChanged();
            }

        });
        viewHolder.checkBox.setChecked(mManagerChecBox[position]);
if(mManagerChecBox[position]){
            viewHolder.imageView_back.setVisibility(View.VISIBLE);
        }else {
            viewHolder.imageView_back.setVisibility(View.INVISIBLE);
        }
return convertView;
    }
class ViewHolder{
    TextView textView;
        ImageView imageView;
        CheckBox checkBox;
        ImageView imageView_back;
    }
}
