点击列表视图时出现问题。当我点击按钮时没有任何反应。我必须开始一个新的活动。
我想知道我的代码有什么问题:
进口
public class CountriesListAdapter extends ArrayAdapter<String> {
private final Context context;
private final String[] values;
ListView listView ;
public CountriesListAdapter(Context context, String[] values) {
super(context, R.layout.country_list_item, values);
this.context = context;
this.values = values;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
LayoutInflater inflater = (LayoutInflater) context
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View rowView = inflater.inflate(R.layout.country_list_item, parent, false);
TextView textView = (TextView) rowView.findViewById(R.id.txtViewCountryName);
ImageView imageView = (ImageView) rowView.findViewById(R.id.imgViewFlag);
String g=values[position];
textView.setText((g).trim());
if (g.equals("1")) {
imageView.setImageResource(R.drawable.ger);
} else if (g.equals("2")) {
imageView.setImageResource(R.drawable.ukra);
} else if (g.equals("3")) {
imageView.setImageResource(R.drawable.k);
} else if (g.equals("4")) {
imageView.setImageResource(R.drawable.wf);
}
return rowView;}
protected void onListItemClick(int position, View convertView, ViewGroup parent) {
String g=values[position];
if (g.equals("4")){
Intent intent = new Intent(context, Spain.class);
context.startActivity(intent);
}}
}

你必须从列表视图添加的活动或片段中调用onitemclick监听器...
例如......
listView = (ListView) findViewById(R.id.custom_list);
listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> a, View v, int position, long id) {
//your code to go to the next activity is here...
}
});
