我有一个ExpandableListView,我想对其进行编辑。因此,当用户在项目上“ longClicks”时,我正在显示“编辑对话框”。但是,当我在组的convertView上实现onLongClickListener时,单击后便不再扩展。如果我注释掉设置onLongClickListener的代码,则该组将按预期扩展。如何阻止LongClickListner窃取该组的convertView中的click事件?
其他人似乎也有这个问题,可以接受的答案是在LongClickListener中返回false,但这对我不起作用。
这是我获取groupView并设置LongClickListener的地方:
...
@Override
public View getGroupView(int groupPosition, boolean isExpanded,
View convertView, ViewGroup parent) {
final Crew crew = (Crew) getGroup(groupPosition);
if (convertView == null) {
LayoutInflater infalInflater = (LayoutInflater) this.context
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
convertView = infalInflater.inflate(R.layout.crew_item_row, null);
}
TextView lblListHeader = (TextView) convertView
.findViewById(R.id.crewTxtView);
lblListHeader.setTypeface(null, Typeface.BOLD);
lblListHeader.setText(crew.getName());
//set ya onlclick listener here too for ya button to add crew member
RelativeLayout addMemberBttn = (RelativeLayout) convertView.findViewById(R.id.addCrewMemberBttn);
addMemberBttn.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
showNewMemberDialog(crew.getId());
}
});
convertView.setOnLongClickListener(new View.OnLongClickListener() {
@Override
public boolean onLongClick(View v) {
showEditCrewDialog(crew);
return false;
}
});
return convertView;
}
对话框方法代码:
private void showEditCrewDialog(final Crew crew){
final Dialog dialog = new Dialog(context);
dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
dialog.setCancelable(false);
dialog.setContentView(R.layout.edit_crew_dialog);
final EditText crewTextBox = (EditText) dialog.findViewById(R.id.crewEditTxt);
crewTextBox.setText(crew.getName());
final ImageView editButton = (ImageView) dialog.findViewById(R.id.editCrewBttn);
editButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
crewTextBox.setEnabled(true);
crewTextBox.setBackgroundResource(R.drawable.textbox);
editButton.setVisibility(View.GONE);
}
});
Button cancelBttn = (Button) dialog.findViewById(R.id.crewCancelBttn);
cancelBttn.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
dialog.dismiss();
}
});
Button updateBttn = (Button) dialog.findViewById(R.id.updateCrewDialogBttn);
updateBttn.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
if(!crewTextBox.isEnabled()) {
dialog.dismiss();
return;
}
String crewName = crewTextBox.getText().toString();
if(crewName.isEmpty()){
Toast.makeText(context, "Crew must have a name...", Toast.LENGTH_SHORT).show();
return;
}
crew.setName(crewName);
CrewService crewService = new CrewService(context);
if(crewService.updateCrew(crew)==0){
Toast.makeText(context, "Error updating crew...", Toast.LENGTH_SHORT).show();
return;
};
notifyDataSetChanged();
Toast.makeText(context, "Crew updated!", Toast.LENGTH_SHORT).show();
dialog.dismiss();
}
});
dialog.show();
}
最佳答案
而不是在getGroupView中,应该从您的活动中调用setOnItemLongListener。在定义可扩展列表视图的活动中使用以下代码。
expandableListView.setOnItemLongClickListener(new OnItemLongClickListener() {
Override
public boolean onItemLongClick( AdapterView<?> parent, View view, int position, long id) {
showEditCrewDialog(crew);
return false;
}
});
