在我的应用程序中,我有ListView和适配器到我的ListView。我的项目ListView有两个元素Text和Image。现在我想分开文本并点击图片。
public class MyAdapter extends ArrayAdapter<String> {
private Activity context;
private ArrayList<String> categories;
public static boolean remove = true;
public MyAdapter(Activity context, ArrayList<String> categories) {
super(context, R.layout.my_list_element, categories);
this.context = context;
this.categories = categories;
}
static class ViewHolder {
public TextView tvLanguage;
public ImageView remove;
}
public View getView(int position, View convertView, ViewGroup parent) {
View rowView = convertView;
if (rowView == null) {
LayoutInflater inflater = context.getLayoutInflater();
rowView = inflater.inflate(R.layout.my_list_element, null);
ViewHolder viewHolder = new ViewHolder();
viewHolder.tvLanguage = (TextView) rowView.findViewById(R.id.tvLanguage);
viewHolder.remove = (ImageView) rowView.findViewById(R.id.remove);
rowView.setTag(viewHolder);
}
ViewHolder holder = (ViewHolder) rowView.getTag();
holder.tvLanguage.setText(categories.get(position));
if(remove)
holder.remove.setVisibility(View.GONE);
else
holder.remove.setVisibility(View.VISIBLE);
return rowView;
}
我应该如何将文本和图像分开并成功在两个元素上使用setOnClickListener?

将第一个块修改为:
if (rowView == null) {
LayoutInflater inflater = context.getLayoutInflater();
rowView = inflater.inflate(R.layout.my_list_element, null);
ViewHolder viewHolder = new ViewHolder();
viewHolder.tvLanguage = (TextView) rowView.findViewById(R.id.tvLanguage);
viewHolder.remove = (ImageView) rowView.findViewById(R.id.remove);
rowView.setTag(viewHolder);
viewHolder.tvLanguage.setOnClickListener(new View.OnClickListener() {
public void onClick(View v){
// handle your text view
}
});
viewHolder.remove.setOnClickListener(new View.OnClickListener() {
public void onClick(View v){
// handle your imageview
}
});
}

尝试为您的意图添加标记 像这样:
Intent i = new Intent (this, AddRSS.class);
i.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity (i);
上面的代码将启动活动,并将成为历史堆栈上新任务的开始。

我解决了我的问题:)我无法使用此代码
Intent i = new Intent (this, AddRSS.class);
startActivity (i);
因为我的MyAdapter类没有扩展Activity所以我无法使用方法startActivity(i);
解决方案很简单,我使用上下文:
Intent i = new Intent (context, AddRSS.class);
context.startActivity (i);
现在有效;)
