三、GridView中Item的点击事件
gridView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
if (position == gridAdapter.getMaxPosition() - 1) {
PhotoPickerIntent intent = new PhotoPickerIntent(MainActivity.this);
intent.setSelectModel(SelectModel.MULTI);
intent.setShowCarema(true); // 是否显示拍照
intent.setMaxTotal(6); // 最多选择照片数量，默认为9
intent.setSelectedPaths(imagePaths); // 已选中的照片地址， 用于回显选中状态
startActivityForResult(intent, REQUEST_CAMERA_CODE);
}else{
PhotoPreviewIntent intent = new PhotoPreviewIntent(MainActivity.this);
intent.setCurrentItem(position);
intent.setPhotoPaths(imagePaths);
startActivityForResult(intent, REQUEST_PREVIEW_CODE);
}
}
});
