我有行列表。如果我想选择一个特定的行并且在＆＃34;相机＆＃34;的onclick事件中按钮应将捕获的图像添加到所选行。但我的问题是捕获的图像正在添加到最后一行。
private void getlist(final ArrayList<Exceptions> exceptionRowsList2) {
lv1.setAdapter(new ArrayAdapter<Exceptions>(getApplicationContext(),
R.layout.damagerow, exceptionRowsList2) {
@Override
public View getView(final int position, View convertView,
ViewGroup parent) {
final View row;
if (null == convertView) {
row = mInflater.inflate(R.layout.damagerow, null);
} else {
row = convertView;
}
TextView errorCode = (TextView) row.findViewById(R.id.error_code);
TextView errorCodeval = (TextView) row.findViewById(R.id.error_code_val);
TextView description = (TextView) row.findViewById(R.id.desc);
TextView descriptionVal = (TextView) row.findViewById(R.id.desc_val);
damage1 = (ImageView) row.findViewById(R.id.damageimage1);
damage2 = (ImageView) row.findViewById(R.id.damageimage2);
damage3 = (ImageView) row.findViewById(R.id.damageimage3);
damage4 = (ImageView) row.findViewById(R.id.damageimage4);
damage1.setImageResource(R.drawable.damage_bg_default);
damage2.setImageResource(R.drawable.damage_bg_default);
damage3.setImageResource(R.drawable.damage_bg_default);
damage4.setImageResource(R.drawable.damage_bg_default);
errorCode.setTextColor(Color.BLACK);
errorCodeval.setTextColor(Color.BLACK);
description.setTextColor(Color.BLACK);
descriptionVal.setTextColor(Color.BLACK);
errorCode.setText("Error Code: ");
errorCodeval.setText(""
+ exceptionRowsList2.get(position).getAreaCode() + "-"
+ exceptionRowsList2.get(position).getTypeCode() + "-"
+ exceptionRowsList2.get(position).getSeverityCode()
.toString());
description.setText("Description: ");
descriptionVal.setText(""
+ exceptionRowsList2.get(position).getAreaDesc() + " - "
+ exceptionRowsList2.get(position).getTypeDesc() + " - "
+ exceptionRowsList2.get(position).getSeverityDesc());
row.setBackgroundResource(R.drawable.error_detail_list_bg);
row.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
row.setBackgroundResource(R.drawable.select_damage);
exceptionRowsList2.get(position).setTakeImage(true);
exceptionRowsList2.get(position).setDelete(true);
}
});
return row;
}
});
}
任何人都可以帮我这个..？ PLZ ...

答案 0 :(得分：2)
所需的输出..实际上，onActivitResult() 中的图片浏览量引用了列表的最后一行。
<强>解决方案：
将图片文件路径存储在数组或列表中，并在onActivityResult()中点击列表视图行的位置，然后从中调用adapter.notifyDatasetChnaged()。
现在，在适配器的getView()检查项目的位置，将您存储在onActivityResult()的数组中，并在此条件下使用存储的图像文件路径Bitmap显示在imageview中。
