ListView未显示所需的记录
我的ListView一次在UI上保存5条记录，默认情况下它可以作为普通listView.Rowdata滚动包含2个参数名称，状态WHen我显示名称的数据正确但状态为前5个记录随机重复。
listdetails.xml
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/scrollView_description"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:fillViewport="true"
android:orientation="vertical" >
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#ffffff"
android:focusableInTouchMode="true"
android:orientation="vertical" >
<LinearLayout
android:id="@+id/timerDisplay"
android:layout_width="match_parent"
android:layout_height="370dp"
android:layout_alignParentTop="true"
android:layout_marginLeft="5dp"
android:layout_marginRight="5dp"
android:background="@drawable/media_player_final"
android:orientation="vertical"
android:scaleType="fitXY" >
has various textViews & ImageViews
</LinearLayout>
<LinearLayout
android:id="@+id/linearLayout1"
android:layout_width="fill_parent"
android:layout_height="250dp"
android:layout_below="@+id/timerDisplay"
android:orientation="vertical" >
<ListView
android:id="@+id/list"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_below="@+id/timerDisplay"
android:layout_marginTop="5dp"
android:cacheColorHint="#ffffff"
android:divider="@android:color/black"
android:dividerHeight="1dp"
android:focusable="false"
android:scrollbars="none"
android:textColor="#000000" />
</LinearLayout>
在 ListDetails.java
中 listViewLinearLayout=(LinearLayout)findViewById(R.id.linearLayout1);
Point size = new Point();
WindowManager w = getWindowManager();
if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB) {
w.getDefaultDisplay().getSize(size);
height=size.y;
}else{
Display d = w.getDefaultDisplay();
height=d.getHeight();
}
height=height-350;
View view_instance = (View)findViewById(R.id.linearLayout1);
LayoutParams params=view_instance.getLayoutParams();
params.height=height;
view_instance.setLayoutParams(params);
And also,
listView.setOnTouchListener(new ListView.OnTouchListener() {
@Override
public boolean onTouch(View v, MotionEvent event) {
int action = event.getAction();
switch (action) {
case MotionEvent.ACTION_DOWN:
// Disallow ScrollView to intercept touch events.
v.getParent().requestDisallowInterceptTouchEvent(true);
break;
case MotionEvent.ACTION_UP:
// Allow ScrollView to intercept touch events.
v.getParent().requestDisallowInterceptTouchEvent(false);
break;
}
// Handle ListView touch events.
v.onTouchEvent(event);
return true;
}
});

调用自定义适配器
CustomAdapter adapter = new CustomAdapter(this, R.layout.episode_list,R.id.textViewAirWayBillNumber, data);
适配器
private class CustomAdapter extends ArrayAdapter<RowData> implements OnClickListener{
ListView lv;
public CustomAdapter(Context context, int resource,int textViewResourceId, List<RowData> objects)
{
super(context, resource, textViewResourceId, objects);
lv=(ListView)findViewById(resource);
}
@Override
public View getView(final int position, View convertView, ViewGroup parent)

if(null == convertView)

}/*else{

holder = (ViewHolder) convertView.getTag();
awbNumber = holder.gettextViewAirWayBillNumber();
// //System.out.println("onkar trying to set name"+rowData.intId+""+rowData.StrID+""+rowData.strname);
awbNumber.setText(rowData.strname );
status=holder.getEpisodeStatus();
imageView=holder.getImageViewHolder();
if(rowData.count==rowData.downloaded){
//imageView.setText("Play");
}else{
float percentage=(float)rowData.downloaded/rowData.count*100;
status.setText("Downloaded "+Math.ceil(percentage)+" % ");
}
return convertView;
}
