存在问题:默认打开本地图库,全部显示正常,但是切换到其他相册,空白展示;
目前作者还未修复此问题,可通过以下方式进行修改:
(1)将源码下载下来;
(2)使用import module的方式,导入到项目中;
(3)找到MatisseActivity,onAlbumSelected()方法中:
private void onAlbumSelected(Album album) {
if (album.isAll() && album.isEmpty()) {
mContainer.setVisibility(View.GONE);
mEmptyView.setVisibility(View.VISIBLE);
} else {
mContainer.setVisibility(View.VISIBLE);
mEmptyView.setVisibility(View.GONE);
Fragment fragment = MediaSelectionFragment.newInstance(album);
// 修复matisse源码存在的,切换其他相册空白问题
Fragment oldFragment = getSupportFragmentManager().findFragmentByTag(MediaSelectionFragment.class.getSimpleName());
if (oldFragment instanceof MediaSelectionFragment) {
MediaSelectionFragment newFragment = (MediaSelectionFragment) oldFragment;
newFragment.destroyManagerLoader();
}
getSupportFragmentManager()
.beginTransaction()
.replace(R.id.container, fragment, MediaSelectionFragment.class.getSimpleName())
.commitAllowingStateLoss();
}
}
(4)在MediaSelectionFragment中添加:
public void destroyManagerLoader() {
mAlbumMediaCollection.onDestroy();
}
(5)在AlbumCollection添加:
public void onDestroy() {
if (mLoaderManager != null) {
mLoaderManager.destroyLoader(LOADER_ID);
}
mCallbacks = null;
}
(6)在MatisseActivity onDestroy中调用即可:
@Override
protected void onDestroy() {
super.onDestroy();
mAlbumCollection.onDestroy();
mSpec.onCheckedListener = null;
mSpec.onSelectedListener = null;
}
