im creating an app for a website, bayfiles.net I have a working listview which receive json data. This is working fine with filename and size, now i also have a ImageView. I want to determin which icon it should put in the icon holder. This is determined by the ending of the filename. e.g. filename ending with ".png" should show icon with "png" text in it. How is done ?
This is my working activity:
public class FilesActivity extends SherlockActivity {
EditText editsearch;
fileObjectAdapter adapter;
String httpurl, sessionId, filetype;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.dblist);
ActionBar abs = getSupportActionBar();
abs.setDisplayHomeAsUpEnabled(false);
abs.setTitle("BAYFILES");
//abs.setIcon(R.drawable.abs_logo);
abs.setDisplayShowCustomEnabled(true);
LayoutParams lp = new LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT, Gravity.RIGHT | Gravity.CENTER_VERTICAL);
View customNav = LayoutInflater.from(this).inflate(R.layout.actionbar, null);
abs.setCustomView(customNav, lp);
abs.setDisplayShowCustomEnabled(true);
abs.setDisplayOptions(abs.DISPLAY_SHOW_HOME|abs.DISPLAY_SHOW_CUSTOM);
abs.setDisplayShowTitleEnabled(true);
Crouton.makeText(this, "You have been signed in!", Style.CONFIRM).show();
ImageButton btnSearch = (ImageButton) findViewById(R.id.action_search);
btnSearch.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
Log.d("Button Click","position");
}
});

return true;
}
});
}
catch(Exception e)
{
e.printStackTrace();
Log.d("log_tag", "Error: " + e.toString());

}
}
My fileObject:
package com.spxc.bayfiles.adapter;
public class fileObject {
private String fileName;
private String size;
private String infoToken;
private String deleteToken;
private String sha1;
private String fileId;
private String fileType;
public String getFileName() {
return fileName;
}
public void setFileName(String fileName) {
this.fileName = fileName;
}
public String getSize() {
return size;
}
public void setSize(String size) {
this.size = size;
}
public String getInfoToken() {
return infoToken;
}
public void setInfoToken(String infoToken) {
this.infoToken = infoToken;
}
public String getDeleteToken() {
return deleteToken;
}
public void setDeleteToken(String deleteToken) {
this.deleteToken = deleteToken;
}
public String getSha1() {
return sha1;
}
public void setSha1(String sha1) {
this.sha1 = sha1;
}
public String getFileId() {
return fileId;
}
public void setFileId(String fileId) {
this.fileId = fileId;
}
public String getFileType(){
return fileType;
}
public void setFileType(String fileType){
this.fileType = fileType;
}
}
And my adaper:
public class fileObjectAdapter extends BaseAdapter {
private static ArrayList<fileObject> searchArrayList;
private LayoutInflater mInflater;
public fileObjectAdapter(Context context, ArrayList<fileObject> results) {
searchArrayList = results;
mInflater = LayoutInflater.from(context);
}
public int getCount() {
return searchArrayList.size();
}
public Object getItem(int position) {
return searchArrayList.get(position);
}
public long getItemId(int position) {
return position;
}
public View getView(int position, View convertView, ViewGroup parent) {
ViewHolder holder;
if (convertView == null) {
convertView = mInflater.inflate(R.layout.dbitems, null);
holder = new ViewHolder();
holder.txtFileName = (TextView) convertView.findViewById(R.id.size);
holder.txtSize = (TextView) convertView.findViewById(R.id.filename);
holder.imgIcon = (ImageView) convertView.findViewById(R.id.typeimg);
convertView.setTag(holder);
} else {
holder = (ViewHolder) convertView.getTag();
}
holder.txtFileName.setText(searchArrayList.get(position).getFileName());
holder.txtSize.setText(searchArrayList.get(position).getSize());
//holder.imgIcon.setImageResource(SET DRAWABLE ACCORDING TO ENDING);
return convertView;
}
static class ViewHolder {
TextView txtFileName;
TextView txtSize;
ImageView imgIcon;
}
public void filter(String charText) {
charText = charText.toLowerCase(Locale.getDefault());
searchArrayList.clear();
if (charText.length() == 0) {
searchArrayList.addAll(searchArrayList);
}
else
{
for (fileObject wp : searchArrayList)
{
if (wp.getFileName().toLowerCase(Locale.getDefault()).contains(charText))
{
searchArrayList.add(wp);
}
}
}
notifyDataSetChanged();
}
}
As you can see, i get the full filename and split it into two pieces. Filename and extension. Then i'll make an if statement to to check which file extension it is. Then i want it to change the icon in the list item according to the file extension. How can this be done?
Any help is much appreciated!
