这里是 ShowData.java
的代码。我正在设置自定义列表视图。现在我需要点击该列表视图上的视图并显示另一个活动,但会强制关闭。它会在 listview.setAdapter(adapter);
上抛出错误。
public class ShowData extends Activity
{
ListView listview;
Intent intent;
ArrayList<BeanClass> datalist;
CustomAdapter adapter;
@Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
listview = (ListView) findViewById(R.id.listView1);
Intent intent = getIntent();
datalist = (ArrayList<BeanClass>) intent.getSerializableExtra("list");
Log.i("Size of ArrayList", "is " +datalist.size());
adapter = new CustomAdapter(ShowData.this, R.layout.customrow , datalist);
listview.setAdapter(adapter);
listview.setOnItemClickListener(new OnItemClickListener()
{
@Override
public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,long arg3)
{
Intent i = new Intent(ShowData.this,DetailActivity.class);
i.putExtra("datalist", datalist);
i.putExtra("position", arg2);
startActivity(i);
}
}
}
这里是CustomAdapter.java
public class CustomAdapter extends ArrayAdapter<BeanClass>
{
Context context;
int layoutResourceId;
BeanClass bc;
ArrayList<BeanClass> vbc;
public CustomAdapter(Context context, int layoutResourceId, ArrayList<BeanClass> vbc)
{
super(context, layoutResourceId, vbc);
this.context=context;
this.layoutResourceId=layoutResourceId;
this.vbc=vbc;
}
@Override
public View getView(int position, View convertView, ViewGroup parent)
{
View row = convertView;
StringReaderHolder holder;
if(row == null)
{
LayoutInflater inflater = ((Activity)context).getLayoutInflater();
row = inflater.inflate(layoutResourceId, parent,false);
holder= new StringReaderHolder();
holder.mytext1 = (TextView) row.findViewById(R.id.textView1);
holder.mytext2 = (TextView) row.findViewById(R.id.textView2);
holder.mytext3 = (TextView) row.findViewById(R.id.textView3);
row.setTag(holder);
}
else
{
holder = (StringReaderHolder) row.getTag();
}
BeanClass bsObject = vbc.get(position);
holder.mytext1.setText(bsObject.name);
holder.mytext2.setText(bsObject.address);
holder.mytext3.setText(bsObject.phone);
return row;
}
static class StringReaderHolder
{
TextView mytext1,mytext2,mytext3;
}
}
我该如何使用 setOnItemClickListener...??? 谢谢...
