在运行时我正在创建linearlayout。创建的线性布局的数量是数据库中的记录数。线性布局有两个文本框和两个按钮。我面临的问题是只有最后一个线性布局的按钮才有效。先前线性布局的按钮不起作用。

尝试使用以下代码..
public class CustAdp extends ArrayAdapter<String> {
Cursor cursor_subCat;
public CustAdp(Context context, Cursor cursor_subcategory) {
super(context, id);
this.cursor_subCat = cursor_subcategory;
cursor_subCat.moveToFirst();
}
public int getCount() {
// TODO Auto-generated method stub
return cursor_subCat.getCount();
}
public String getItem(int position) {
// TODO Auto-generated method stub
cursor_subCat.moveToPosition(position);
return cursor_subCat.getString(cursor_subCat
.getColumnIndex("Sub_CatName"));
}
public long getItemId(int position) {
// TODO Auto-generated method stub
cursor_subCat.moveToPosition(position);
return cursor_subCat.getInt(cursor_subCat
.getColumnIndex("Sub_IdAuto"));
}
@Override
public void notifyDataSetChanged() {
// TODO Auto-generated method stub
super.notifyDataSetChanged();
cursor_subCat.requery();
}
public View getView(int position, View convertView, ViewGroup parent) {
// TODO Auto-generated method stub
convertView = getLayoutInflater().inflate(R.layout.customsubcat,
null);
ImageView iv_subcat = (ImageView) convertView
.findViewById(R.id.image_region1);
TextView tv_subcat = (TextView) convertView
.findViewById(R.id.txt_regionname1);
Button btn_subcat = (Button) convertView
.findViewById(R.id.button_delete_subcat);
cursor_subCat.moveToPosition(position);
try {
byte[] subimage = cursor_subCat.getBlob(cursor_subCat
.getColumnIndex("Sub_CatImage"));
Bitmap bm = BitmapFactory.decodeByteArray(subimage, 0,
subimage.length);
iv_subcat.setImageBitmap(bm);
tv_subcat.setText(cursor_subCat.getString(cursor_subCat
.getColumnIndex("Sub_CatName")));
subcat_id = cursor_subCat.getLong(cursor_subCat

btn_subcat.setId((int) subcat_id);

根据您的要求对上述代码进行更改...希望它能帮到您..

因为我的朋友，你正在将“onclicklistener”设置为“findViewById”选择的视图（在while循环之前），因此只将监听器设置为一组视图。 你想要做什么把“function（）”的内容放在循环中，并将该函数的视图名称更改为while循环内的视图名称。
离。
while(cur.moveToNext()){
btnbuy=new Button(this);
btnbuy.setId(i);
btnbuy.setHeight(55);
btnbuy.setWidth(75);
btnbuy.setTextColor(Color.rgb(105, 160, 38));
btnbuy.setBackgroundResource(R.drawable.buy_stock);
btnbuy.setOnClickListener(new View.OnClickListener(){
public void onClick(View v) {
Log.d("button id : ",""+btnbuy.getId());
}
});
...
}
