嗨，我正在尝试创建一个将用户发送到链接的onclick事件。但是，我无法弄清楚如何让它发挥作用。
这是我的自定义适配器getview功能
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;
}
我有一个带有url字符串的ArrayList。此ArrayList称为linkData。我尝试了多种方法，但无法弄清楚如何使其工作。我尝试在自定义适配器中添加这些函数1以返回url：
public String getLink(int position) {
return linkData.get(position);
}
这在mainactivity.java中，其中m_listview是listview，mAdapter是自定义适配器
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);
}
}
});
}
然而，这只会导致我的应用程序崩溃而不是去任何地方。
非常感谢有关此事的任何帮助和专业知识。谢谢！

答案 0 :(得分：1)
试着这样： -
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);
}
}
});
}
