我在一个单独的项目中实现了一个ListView
来自sqlite的头文件,如下所示:
当我在滑块菜单的位置实现onClick()
时,它显示在滑块菜单中而不是后台View
onCreate()
代码段
if(position == 3)
{
mAdapter = new MyCustomAdapter();
mAdapter.addSeparatorItem(q.get(0).getA_name());
mAdapter.addItem(q.get(0).getAS_name());
for (int i = 1; i < 460; i++) {
if (!(q.get(i).getA_name().trim().equals(q.get(i-1).getA_name().trim()))) {
mAdapter.addSeparatorItem(q.get(i).getA_name());
c++;
}
mAdapter.addItem(q.get(i).getAS_name());
}
setListAdapter(mAdapter);
toggleMenu(arg1);
}
适配器类
//Adapter Class
private class MyCustomAdapter extends BaseAdapter {
private static final int TYPE_ITEM = 0;
private static final int TYPE_SEPARATOR = 1;
private static final int TYPE_MAX_COUNT = TYPE_SEPARATOR + 1;
private ArrayList<String> mData = new ArrayList<String>();
private LayoutInflater mInflater;
private TreeSet<Integer> mSeparatorsSet = new TreeSet<Integer>();
public MyCustomAdapter() {
mInflater = (LayoutInflater)getSystemService(Context.LAYOUT_INFLATER_SERVICE);
}
public void addItem(final String item) {
mData.add(item);
notifyDataSetChanged();
}
public void addSeparatorItem(final String item) {
mData.add(item);
// save separator position
mSeparatorsSet.add(mData.size() - 1);
notifyDataSetChanged();
}
@Override
public int getItemViewType(int position) {
return mSeparatorsSet.contains(position) ? TYPE_SEPARATOR : TYPE_ITEM;
}
@Override
public int getViewTypeCount() {
return TYPE_MAX_COUNT;
}
public int getCount() {
return mData.size();
}
public String getItem(int position) {
return mData.get(position);
}
public long getItemId(int position) {
return position;
}
public View getView(final int position, View convertView, ViewGroup parent) {
ViewHolder holder = null;
int type = getItemViewType(position);
System.out.println("getView " + position + " " + convertView + " type = " + type);
if (convertView == null) {
holder = new ViewHolder();
switch (type) {
case TYPE_ITEM:
convertView = mInflater.inflate(R.layout.activity_main1, null);
holder.textView = (TextView)convertView.findViewById(R.id.text);
holder.textView.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
AlertDialog.Builder nointernetconnection = new AlertDialog.Builder(
temp);
nointernetconnection
.setIcon(R.drawable.ic_launcher)
.setTitle(q.get(position-1).getAS_name())
.setMessage(q.get(position-1).getDesc_art())
.setCancelable(true)
.setPositiveButton("OK",
new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface arg,
int arg1) {
}
});
AlertDialog a = nointernetconnection.create();
a.show();
}
});
break;
case TYPE_SEPARATOR:
convertView = mInflater.inflate(R.layout.activity_main2, null);
holder.textView = (TextView)convertView.findViewById(R.id.textSeparator);
break;
}
convertView.setTag(holder);
} else {
holder = (ViewHolder)convertView.getTag();
}
holder.textView.setText(mData.get(position));
return convertView;
}
}
public static class ViewHolder {
public TextView textView;
}
因此,MyCustomAdapter类在滑块菜单中显示该列表。但是此列表不应显示在滑块菜单中,而应显示在滑块菜单后面。我希望问题很清楚。请告诉我的错误。
答案 0 :(得分:0)
正在为滑块调用您正在调用的setlistadapter方法,而不是后台活动/片段的列表视图。
执行ListView list = (ListView) getactivity().findViewById(R.id.yourListViewName)
或类似的操作,然后设置列表适配器。
