我已經實現了自定義SimpleCursorAdapter
以將圖像和文本插入我的ListView
,但是當用戶滾動時圖像四處移動。我怎樣才能讓他們留在原地?這裏是我的代碼(我剝離下來爲簡單起見):滾動ListView混合圖像
final class mySimpleCursorAdapter extends SimpleCursorAdapter {
public mySimpleCursorAdapter(Context context, int layout, Cursor cur,
String[] from, int[] to) {
super(context, layout, cur, from, to);
mContext = context;
mLayoutInflater = LayoutInflater.from(context);
}
@Override
public View newView(Context context, Cursor cursor, ViewGroup parent) {
View v = mLayoutInflater.inflate(R.layout.row, parent, false);
return v;
}
@Override
public void bindView(View v, Context context, Cursor c) {
ImageView bar11 = (ImageView) v.findViewById(R.id.bar);
ImageView bar12 = (ImageView) v.findViewById(R.id.bar2);
ImageView bar13 = (ImageView) v.findViewById(R.id.bar3);
TextView sign = (TextView) v.findViewById(R.id.text3);
sign.setText(currency);
if (someValue == 0){
bar11.setVisibility(View.GONE);
}
if (someValue == 1){
bar12.setVisibility(View.VISIBLE);
}
if (someValue == 2){
bar13.setVisibility(View.VISIBLE);
}
}
}

你的檢查應該看起來像這樣if(someValue == 0){ bar11.setVisibility(View.GONE); }其他{bar11.setVisibility(View.VISIBLE);}'由於查看回收 – Amal
嗯,我實際上有3個圖像,這意味着我需要至少有兩個「如果」,這就是我遇到問題的地方.. 。我應該早點指定 – 725623452362
你可以在這裏粘貼你的xml嗎? –
