您好我尝试在Gridview上使用我自己的适配器。
我的问题是getView中的位置没有增加。
这是我的代码：
public class WorkourLogBuilder {
String[] values = new String[11];
Context mContext;
Map<Integer, String[]> valuesArray;
int rowsCount = 0;
int mode;
int adappterRowsCount = 0;
static final int AEROBIC = 1;
static final int ANAEROBIC = 0;
public WorkourLogBuilder(Context context, int modeChoosed)
{
mContext = context;
mode = modeChoosed;
valuesArray = new HashMap<Integer, String[]>();
}
public void commintRow()
{
valuesArray.put(rowsCount, values);
rowsCount++;
Log.i("rowsCount", rowsCount+"");
values = new String[11];
}
public void setWorkoutWeight(String value)
{
values[0] = value;
}
public void setSets(String value)
{
values[1] = value;
}
public void setReps(String value)
{
values[2] = value;
}
public void setWorkTime(String value)
{
values[3] = value;
}
public void setWDayTime(String value)
{
values[4] = value;
}
public void setDistance(String value)
{
values[5] = value;
}
public void setSpeed(String value)
{
values[6] = value;
}
public void setRestTime(String value)
{
values[7] = value;
}
public void setCaloires(String value)
{
values[8] = value;
}
public void setHeartBeat(String value)
{
values[9] = value;
}
public void setComment(String value)
{
values[10] = value;
}
public View build()
{
LayoutInflater inflater = ((Activity) mContext).getLayoutInflater();
View v = inflater.inflate(R.layout.workout_log_row, null, false);
GridView grid = (GridView) v.findViewById(R.id.table);
Log.i("count", valuesArray.size()+"");
grid.setAdapter(new ImageAdapter());
return v;
}
public class ImageAdapter extends BaseAdapter {
public int getCount() {
return (valuesArray.size()+6);
}
public Object getItem(int position) {
return valuesArray.get(position);
}
public long getItemId(int position) {
return position;
}
public View getView(int position, View convertView, ViewGroup parent) {
Log.i("position", position+"");
if(position < 6)
{

if(position < 3)
image.setImageDrawable(mContext.getResources().getDrawable(R.drawable.small_green_apple));
else
image.setImageDrawable(mContext.getResources().getDrawable(R.drawable.anonymous));
image.setScaleType(ImageView.ScaleType.FIT_XY);
return image;
}
TextView textValue = new TextView(mContext);
textValue.setTextColor(Color.BLACK);
GridView.LayoutParams lp = new GridView.LayoutParams(GridView.LayoutParams.WRAP_CONTENT, GridView.LayoutParams.MATCH_PARENT);
textValue.setLayoutParams(lp);
String[] currecntRow = valuesArray.get(adappterRowsCount);
switch(position % 6)
{
case 0:
{
if(adappterRowsCount != 6)
adappterRowsCount++;
if(mode == AEROBIC)
textValue.setText(currecntRow[5]);
else
textValue.setText(currecntRow[0]);
break;
}
case 1:
{
if(mode == AEROBIC)
textValue.setText(currecntRow[3]);
else
textValue.setText(currecntRow[2]);
break;
}
case 2:
{
if(mode == AEROBIC)
textValue.setText(currecntRow[6]);
else
textValue.setText(currecntRow[1]);
break;
}
case 3:
{
if(mode == AEROBIC)
textValue.setText(currecntRow[1]);
else
textValue.setText(currecntRow[7]);
break;
}
case 4:
{
if(mode == AEROBIC)
textValue.setText(currecntRow[7]);
else
textValue.setText(currecntRow[3]);
break;
}
case 5:
{
if(mode == AEROBIC)
textValue.setText(currecntRow[10]);
else
textValue.setText(currecntRow[10]);
break;
}
}
return textValue;
}

当我看到logcat i时，位置记录始终为0。
为什么位置没有增加？
答案 0 :(得分：3)
您未正确返回getItem()：
public Object getItem(int position) {
return position;
}
应该是：
public Object getItem(int position) {
return valuesArray.get(position);
}
答案 1 :(得分：2)
getItem()
public Object getItem(int position) {
return valuesArray.get(position);
}
它应该返回Object而不是位置，所以基本上它总是返回0
