I have a custom list view where each list item has two buttons, one text view and one seek bar where the seek bar visibility is set to gone in list item's XML.
Now what I want to do is on click of button one in the list item I want to hide the text view and display the seek bar of that list item whose button is clicked and show hide the seek bar and display the text view of all other list items.
The code that I have written works well if the total items are less than the views that can be displayed at once in a list view but for a lot of views this does not works.
What I am doing is load a list of files from a a folder into the list view and play the in the list view only
Please tell me where I am going wrong.
Any help would be appreciated.

You have to set the listeners for the button in the Adapter class getView method.
#Override
public View getView(int position, View convertView, ViewGroup parent) {
RowViewHolder viewHolder;
if (convertView == null) {
convertView = inflater.inflate(R.layout.audio_file_list_item, null);
viewHolder = new RowViewHolder();
viewHolder.fileName = (TextView) convertView.findViewById(R.id.file_name);
viewHolder.filePlay = (Button) convertView.findViewById(R.id.file_play);
viewHolder.filePlay.setOnClickListener(new OnClickListener(){
#Override
public void onClick(View view){
// Do Your Work Here
}
});
viewHolder.filePlay.setTag(position);
viewHolder.rate = (Button) convertView.findViewById(R.id.rate);
viewHolder.fileSeek = (SeekBar) convertView.findViewById(R.id.file_seek);
viewHolder.filePlay.setOnClickListener(mListener);
viewHolder.rate.setOnClickListener(mListener);
convertView.setTag(viewHolder);
} else {
viewHolder = (RowViewHolder) convertView.getTag();
}
viewHolder.fileName.setText(fileList.get(position));
return convertView;
}

You only set the Button play when type == TYPE_ITEM3, but you always call holder.play.setOnClickListener. Hence you either only call the setOnClickListener method when play is not null, e.i:
if(holder.play != null){
holder.play.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
//mycode
}
});
}
Or you always set the play button to a Button object

Please help me how can fix this issue
Thanks In Advance
this is not a perfect solution if it works according to ur requirment. then update the solution withot switch.

I have a list in which each element on a player. When I click on "start" and a song starts playing strip seekbar starts moving. when click on the "stop" the song stops playing and the strip stops. But if while moving the strip I scroll list and it goes off the screen, it starts to move another strip that is on the same position in the visible area of the screen.

EDIT:
I added geter and seter in recordBean
public int getSeekPos() {
return SeekPos;
}
public void setSeekPos(int seekPos) {
SeekPos = seekPos;
}
and
holder.seekBar.setProgress(recordBeans.get(position).getSeekPos());
holder.date.setText(" " + recordBeans.get(position).getDate());
and
#Override
public void onProgressChanged(final SeekBar seekBar, final int i, boolean b) {
if (b && (Integer)seekBar.getTag()==global_position) {
// mediaPlayer.seekTo(i);
recordBeans.get(position).setSeekPos(i);
}
}
but I think it left something extra in my code
The list item is being recycled when it leaves the screen.
You could try to call this in getView:
holder.seekBar.clearFocus();
This is a tricky process, but you can do this in the following way, as I have seen that you have created a List of RecordBean class. So what you can do is you have to create a Getter Setter in RecordBean for storing the position of you SeekBar like:
public void setSeekPos(int pos) {
this.pos = pos;
}
public int getSeekPos() {
return pos;
}
In your adapter below the line
holder.date.setText(" " + recordBeans.get(position).getDate());
set the progress of seekBar like this: holder.seekBar.setProgress(recordBeans.get(position).getSeekPos());
and inside the onProgressChanged add the following line recordBeans.get(position).setSeekPos(i);
This will resolve your issue.
Please let me know if it's working or not.
Thanks
I use PulltoRefresh listview and I use 3 layouts.
1. Gaming Layout(Should be inflated when linkedlist item starts with "gm")
2. Adlayout(Should be inflated when linkedlist item starts with "ad")
3.Normal Listview layout(in all other cases)
Here is the code
mListItems = new LinkedList<String>();
mListItems.add(0,"hi1");
mListItems.add(1,"hi2");
mListItems.add(2,"gm");
mListItems.add(3,"hi3");
mListItems.add(4,"ad");
mListItems.add(5,"hi4");
((PullToRefreshListView) getListView())
.setOnRefreshListener(new OnRefreshListener() {
#Override
public void onRefresh() {
// Do work to refresh the list here.
new GetDataTask().execute();
}
});
private class GetDataTask extends AsyncTask<Void, Void, String[]> {
#Override
protected String[] doInBackground(Void... params) {
// Simulates a background job.
try {
Thread.sleep(2000);
} catch (InterruptedException e) {
;
}
return mStrings;
}
#Override
protected void onPostExecute(String[] result) {
// mListItems.addFirst("Added after refresh...");
// parseJson("IndigoFM_06212013.json");
mListItems.addFirst("how are you");
mListItems.addFirst("ad");
mListItems.addFirst("gm");
mListItems.addFirst("the end");
// Call onRefreshComplete when the list has been refreshed.
((PullToRefreshListView) getListView()).onRefreshComplete();
super.onPostExecute(result);
}
}
Here is the adapter code
private class basicListAdapter extends BaseAdapter {
#Override
public int getCount() {
// TODO Auto-generated method stub
return mListItems.size();
}
#Override
public Object getItem(int position) {
// TODO Auto-generated method stub
return mListItems.get(position);
}
#Override
public long getItemId(int position) {
// TODO Auto-generated method stub
return position;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
// TODO Auto-generated method stub
View v = convertView;
if (v == null) {
LayoutInflater inflater = LayoutInflater
.from(getApplicationContext());
if ((mListItems.get(position).startsWith("gm"))) {
v = inflater.inflate(R.layout.gaminglayout, null);
} else if ((mListItems.get(position).startsWith("ad"))) {
v = inflater.inflate(R.layout.adlayout, null);
} else if(!(mListItems.get(position).startsWith("gm")) && !(mListItems.get(position).startsWith("ad"))) {
v = inflater.inflate(R.layout.listinflate, null);
}
viewHolder holder = new viewHolder();
adViewHolder adHolder = new adViewHolder();
gamingViewHolder gamingHolder = new gamingViewHolder();
if ((mListItems.get(position).startsWith("ad"))) {
adHolder.adDetails = (TextView) v.findViewById(R.id.adText);
v.setTag(adHolder);
} else if ((mListItems.get(position).startsWith("gm"))) {
gamingHolder.gamingButton = (Button) v
.findViewById(R.id.gamingButton);
gamingHolder.gamingButton .setOnClickListener(mOngamingButtonClickListener);
v.setTag(gamingHolder);
}else if(!(mListItems.get(position).startsWith("gm")) && !(mListItems.get(position).startsWith("ad"))){
holder.rjName = (TextView) v.findViewById(R.id.rjName);
holder.textViewName = (TextView) v
.findViewById(R.id.textViewName);
holder.likeLayout = (LinearLayout) v
.findViewById(R.id.likeLayout);
holder.commentLayout = (LinearLayout) v
.findViewById(R.id.commentLayout);
holder.likeLayout
.setOnClickListener(mOnLikeLayoutClickListener);
holder.commentLayout
.setOnClickListener(mOnCommentLayoutClickListener);
v.setTag(holder);
}
}
if (mListItems.get(position) != null) {
// if(!(mListItems.get(position).startsWith("1"))){
if (!(v.getTag() instanceof adViewHolder)) {
if(!(v.getTag() instanceof gamingViewHolder)){
viewHolder holder = (viewHolder) v.getTag();
holder.textViewName.setText(mListItems.get(position));
}
}
}
return v;
}
}
Now the issue is that after I pull to refresh, The entries which start with "gm" are being shown in normal listview layout but not the gaming layout.
In a way to say incorrect layout is being inflated
