我使用自定义适配器动态创建了GridView。单击GridView项目时，我必须在其下显示一个气泡。我正在使用RelativeLayout，但每次在左上角显示气泡时。
这是我的自定义适配器
public class GridAdapter extends BaseAdapter {
private Context mContext;
private GridItem[] items;
public GridAdapter(Context c) {
mContext = c;
items = GridItem.values();
//inflater = (LayoutInflater) activity.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
}
public int getCount() {
return items.length;
}
public GridItem getItem(int position) {
return items[position];
}
public long getItemId(int position) {
return items[position].getResourceId();
}
public static class ViewHolder {
public ImageView image;
}
public View getView(int position, View convertView, ViewGroup parent) {
ImageView imageView;
if (convertView == null) {
imageView = new ImageView(mContext);
imageView.setLayoutParams(new GridView.LayoutParams(GridView.LayoutParams.WRAP_CONTENT,
GridView.LayoutParams.WRAP_CONTENT));
//imageView.setPadding(10, 10, 10, 10);
} else {
imageView = (ImageView) convertView;
}
imageView.setBackgroundResource(items[position].getResourceId());
if (position == 3) {
ImageView helpBubble = new ImageView(mContext);
}
//imageView.setTag(items[position]);
return imageView;
}
}
以下是设置气泡的代码
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
GridItem item = GridItem.values()[position];
if (position != 6) {
Toast.makeText(HelpModeActivity.this, "Clicked on : " + item.getResourceId(), Toast.LENGTH_LONG)
.show();
LayoutInflater inflate = (LayoutInflater) mContext
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
RelativeLayout helpBubble = (RelativeLayout) inflate.inflate(R.layout.bubble, null);
TextView helpText = (TextView) helpBubble.findViewById(R.id.bubble_text);
helpText.setText("Lorem Epsum Dolor Emit ab asdfj asdflqwe fsadf wqrwqer asdfasdf wfsad asdfasdf rqwerqwrw");
Button moreButton = (Button) helpBubble.findViewById(R.id.bubble_button);
moreButton.setText("More Info");
RelativeLayout.LayoutParams lp = new RelativeLayout.LayoutParams(
RelativeLayout.LayoutParams.WRAP_CONTENT, RelativeLayout.LayoutParams.WRAP_CONTENT);
lp.addRule(RelativeLayout.BELOW, item.getResourceId());
gridRL.addView(helpBubble, lp);
}
我哪里错了???
