当我点击按钮时,我有一个exeption并强制关闭
适配器代码:
public class myAdapter extends BaseAdapter implements OnClickListener {
private ArrayList<produit> produits;
private LayoutInflater myInflater;
public myAdapter(Context context, ArrayList<produit> _produits) {
this.myInflater = LayoutInflater.from(context);
this.produits = _produits;
}
@Override
public int getCount() {
// TODO Auto-generated method stub
return this.produits.size();
}
@Override
public Object getItem(int arg0) {
// TODO Auto-generated method stub
return this.produits.get(arg0);
}
@Override
public long getItemId(int position) {
// TODO Auto-generated method stub
return position;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
if (null == convertView) {
convertView = myInflater.inflate(R.layout.listitem, null);
}
Button btn = (Button) convertView.findViewById(R.id.button1);
btn.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
Intent i = new Intent(v.getContext(), Local.class);
v.getContext().startActivity(i);
}
});
// set the text
TextView tv = (TextView) convertView.findViewById(R.id.textView1);
tv.setText(produits.get(position).nom);
return convertView;
}
@Override
public void onClick(View v) {
Log.v("bonjour", "Row button clicked");
}
}
主要代码:
public class Main extends Activity {
private ArrayList<produit>produits=new ArrayList<produit>();
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
produits.add(new produit("marlboro"));
produits.add(new produit("sabrine"));
ListView list = (ListView)findViewById(R.id.listView1);
myAdapter adpt = new myAdapter (this,produits);
list.setAdapter(adpt);
}
}
logcat的:

我该如何做到这一点?
答案 0 :(得分:1)
尝试:
private ArrayList<produit> produits;
private LayoutInflater myInflater;
private Context context
public myAdapter(Context context, ArrayList<produit> _produits) {
this.myInflater = LayoutInflater.from(context);
this.produits = _produits;
this.context = context;
}
@Override
public int getCount() {
// TODO Auto-generated method stub
return this.produits.size();
}
@Override
public Object getItem(int arg0) {
// TODO Auto-generated method stub
return this.produits.get(arg0);
}
@Override
public long getItemId(int position) {
// TODO Auto-generated method stub
return position;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
if (null == convertView) {
convertView = myInflater.inflate(R.layout.listitem, null);
}
Button btn = (Button) convertView.findViewById(R.id.button1);
btn.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
Intent i = new Intent(context, Local.class);
context.startActivity(i);
}
});
// set the text
TextView tv = (TextView) convertView.findViewById(R.id.textView1);
tv.setText(produits.get(position).nom);
return convertView;
}
@Override
public void onClick(View v) {
Log.v("bonjour", "Row button clicked");
}
}

猜猜:你确定你在这里得到了正确的背景吗?
Intent i = new Intent(v.getContext(), Local.class);
