将位图插入到GridView中的步骤如下:
以下是一个示例代码:
public class ImageAdapter extends BaseAdapter {
private Context mContext;
private List<Bitmap> mBitmapList;
public ImageAdapter(Context context, List<Bitmap> bitmapList) {
mContext = context;
mBitmapList = bitmapList;
}
@Override
public int getCount() {
return mBitmapList.size();
}
@Override
public Object getItem(int position) {
return mBitmapList.get(position);
}
@Override
public long getItemId(int position) {
return position;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
if (convertView == null) {
LayoutInflater inflater = LayoutInflater.from(mContext);
convertView = inflater.inflate(R.layout.grid_item, parent, false);
}
ImageView imageView = convertView.findViewById(R.id.image_view);
imageView.setImageBitmap(mBitmapList.get(position));
return convertView;
}
}
在Activity中的代码:
public class MainActivity extends AppCompatActivity {
private GridView mGridView;
private ImageAdapter mImageAdapter;
private List<Bitmap> mBitmapList;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mGridView = findViewById(R.id.grid_view);
mBitmapList = new ArrayList<>();
// 添加位图到mBitmapList中
mImageAdapter = new ImageAdapter(this, mBitmapList);
mGridView.setAdapter(mImageAdapter);
}
}
