ListView Custom Adapter OnClick launch URL link
Hi so I'm trying to create an onclick event which will send the user to a link. However I couldn't figure out how to get it to work.
This is my Custom Adapter getview function
public View getView(int position, View convertView, ViewGroup parent) {
ViewHolder holder = null;
int rowType = getItemViewType(position);
if (convertView == null) {
holder = new ViewHolder();
switch (rowType) {
case TYPE_ITEM:
convertView = mInflater.inflate(R.layout.program_list, null);
holder.textView = (TextView) convertView.findViewById(R.id.textView1);
holder.imgView = (ImageView) convertView.findViewById(R.id.imageView1);
break;
case TYPE_SEPARATOR:
convertView = mInflater.inflate(R.layout.program_header, null);
holder.textView = (TextView) convertView.findViewById(R.id.textSeparator);
break;
}
convertView.setTag(holder);
} else {
holder = (ViewHolder) convertView.getTag();
}
if(imageData.get(position) == null) {
holder.textView.setText(mData.get(position));
}
else {
holder.textView.setText(mData.get(position));
holder.imgView.setImageResource(imageData.get(position));
}
return convertView;
}
I have an ArrayList with url strings in it. This ArrayList is called linkData. I have tried multiple ways but couldnt figure out how to make it work. I tried to add these functions, 1 in the custom adapter to return the url:
public String getLink(int position) {
return linkData.get(position);
}
and this in the mainactivity.java where m_listview is the listview and mAdapter is the custom adapter
m_listview.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
if (mAdapter.getLink(position) == null) {}
else {
String linked = mAdapter.getLink(position);
Uri url = Uri.parse(linked);
Intent intent = new Intent(Intent.ACTION_VIEW, url);
startActivity(intent);
}
}
});
}
This however only causes my app to crash instead of going anywhere.
Any help and expertise on the matter would be greatly appreciated. Thanks!

try to this:-
m_listview.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
if (mAdapter.getLink(position) == null) {}
else {
String linked = mAdapter.getLink(position);
Uri url = Uri.parse("https://"+linked);
Intent intent = new Intent(Intent.ACTION_VIEW, url);
startActivity(intent);
}
}
});
}
