//添加文件到文件库
public boolean onGroupClick(ExpandableListView parent, View v,
int groupPosition, long id) {
if (doWhat == FILE_LIB_ADD) { //文件添加到库中
ArrayList child =
childList.get(groupPosition);
if (!fm.isMultFile()) { //是否选择了多个文件
if (child.contains(path)) { //是否包含了路径
Toast.makeText(fm, path + "已存在", //文件已经存在
Toast.LENGTH_SHORT).show();
return false;
}
child.add(path); //添加文件
} else {
ArrayList fis =
fileManager.currentFileInfo(); //添加当前文件信息
ArrayList fTmp =
fileManager.selectedItem(); //选中的
int size = fTmp.size();
String tmp;
for (int i = 0; i < size; i++){
tmp = fis.get(fTmp.get(i)).path(); //循环获得文件路径
if (child.contains(tmp)) {
continue;
}
child.add(tmp);
}
}
FileLibDialog.this.dismiss(); //关闭对话框
