Question

android adapter中怎么调用getresources

Answer 1

class FileAdapter extends BaseAdapter{

Context mContext;

LayoutInflater mLInflater;

public FileAdapter (Context context) {

this.mContext= context;

//mListFile=getFileData(path);

this.mLInflater = LayoutInflater.from(context);

}

@Override

public int getCount() {

if(mListFile.size()!=0&&mListFile!=null){

return mListFile.size();

}else{

return 0;

}

}

@Override

public Object getItem(int position) {

return mListFile.get(position);

}

@Override

public long getItemId(int position) {

return position;

}

@Override

public View getView(int position, View convertView, ViewGroup parent) {

ViewHolder holder = null ;

if(convertView==null){

convertView = mLInflater.inflate(R.layout.sd_card_item, null);

holder = new ViewHolder();

holder.setFileName((TextView)convertView.findViewById(R.id.filename));

//holder.setmLastTime((TextView)convertView.findViewById(R.id.time));

holder.setImageIcon((ImageView)convertView.findViewById(R.id.image));

convertView.setTag(holder);

}else {

holder = (ViewHolder)convertView.getTag();

}

int id = 0;

String type = mListFile.get(position).getFileType();

if(type=="0"){

id = R.drawable.up1;

}else if(type=="1"){

id = R.drawable.sdcard0;

}else if(type=="2"){

id = R.drawable.folder2;

}else if(type=="3"){

id= R.drawable.other3;

}else if(type=="55"){

id=R.drawable.none;

}

holder.getFileName().setText(mListFile.get(position).getFileName());

holder.getImageIcon().setImageBitmap(BitmapFactory.decodeResource(mContext.getResources(), id));

holder.getmLastTime().setText(mListFile.get(position).getFileLastTime());

return convertView;

}

}
private class ViewHolder {

TextView fileName;

TextView mLastTime;

ImageView imageIcon;

public TextView getFileName() {

return fileName;

}

public void setFileName(TextView fileName) {

this.fileName = fileName;

}

public TextView getmLastTime() {

return mLastTime;

}

public void setmLastTime(TextView mLastTime) {

this.mLastTime = mLastTime;

}

public ImageView getImageIcon() {

return imageIcon;

}

public void setImageIcon(ImageView imageIcon) {

this.imageIcon = imageIcon;

}

}
代码中mListFile 为这个自定义的类型List;相信有上面部分还是相对来说比较好理解的！
