i have a ExpanableListView that i'm texting. I have a problem with the
expand icon of the items. The icon is being painted overlaying the text
title of each item. It means that for example, if the title of the first
items is "Ducados", the icon is overlaying "Du" and only "cados" is visible
What can i do to align the text on the right of the expand icon?
this is the code:
public class MainActivity extends ExpandableListActivity {ExpandableListAdapter
mAdapter;
@Overridepublic void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// Set up our adapter
mAdapter = new MyExpandableListAdapter();
setListAdapter(mAdapter);
registerForContextMenu(getExpandableListView());}
@Overridepublic void onCreateContextMenu(ContextMenu menu, View v,
ContextMenuInfo menuInfo) {
menu.setHeaderTitle("Sample menu");
menu.add(0, 0, 0, "Sample action");}
@Overridepublic boolean onContextItemSelected(MenuItem item) {
ExpandableListContextMenuInfo info = (ExpandableListContextMenuInfo)
item.getMenuInfo();
String title = ((TextView) info.targetView).getText().toString();
int type = ExpandableListView.getPackedPositionType(info.packedPosition);
if (type == ExpandableListView.PACKED_POSITION_TYPE_CHILD) {
int groupPos =
ExpandableListView.getPackedPositionGroup(info.packedPosition);
int childPos =
ExpandableListView.getPackedPositionChild(info.packedPosition);
Toast.makeText(this, title + ": Child " + childPos + " clicked in group
" + groupPos, Toast.LENGTH_SHORT).show();
return true;
} else if (type == ExpandableListView.PACKED_POSITION_TYPE_GROUP) {
int groupPos =
ExpandableListView.getPackedPositionGroup(info.packedPosition);
Toast.makeText(this, title + ": Group " + groupPos + " clicked",
Toast.LENGTH_SHORT).show();
return true;
}
return false;}
public class MyExpandableListAdapter extends BaseExpandableListAdapter {
// Sample data set. children[i] contains the children (String[]) for
groups[i].
private String[] groups = { "Names", "Designation", "Gender", "Company" };
private String[][] children = {
{ "abc", "xyz", "ash", "anu" },
{ "SSE", "TJ", "PM", "SE" },
{ "Male", "Female Female Female Female Female Female Female Female
Female Female Female Female Female Female Female Female Female Female Female
Female Female Female Female Female Female Female Female Female Female Female
Female Female Female Female Female Female Female Female Female Female " },
{ "yyyyyy", "xxxxx" }
};
public Object getChild(int groupPosition, int childPosition) {
return children[groupPosition][childPosition];
}
public long getChildId(int groupPosition, int childPosition) {
return childPosition;
}
public int getChildrenCount(int groupPosition) {
return children[groupPosition].length;
}
public TextView getGenericView() {
// Layout parameters for the ExpandableListView
AbsListView.LayoutParams lp = new
AbsListView.LayoutParams(ViewGroup.LayoutParams.FILL_PARENT,
ViewGroup.LayoutParams.WRAP_CONTENT);
TextView textView = new TextView(MainActivity.this);
textView.setLayoutParams(lp);
textView.setTextSize(20);
// Center the text vertically
textView.setGravity(Gravity.CENTER_VERTICAL | Gravity.LEFT);
return textView;
}
public View getChildView(int groupPosition, int childPosition, boolean
isLastChild, View convertView, ViewGroup parent) {
TextView textView = getGenericView();
textView.setText(getChild(groupPosition, childPosition).toString());
textView.setTextSize(15);
return textView;
}
public Object getGroup(int groupPosition) {
return groups[groupPosition];
}
public int getGroupCount() {
return groups.length;
}
public long getGroupId(int groupPosition) {
return groupPosition;
}
public View getGroupView(int groupPosition, boolean isExpanded, View
convertView, ViewGroup parent) {
TextView textView = getGenericView();
textView.setText(getGroup(groupPosition).toString());
return textView;
}
public boolean isChildSelectable(int groupPosition, int childPosition) {
return true;
}
public boolean hasStableIds() {
return true;
} }}
