I have an array of images and string like this:
String[] stations = new String[] {
"GHOTKI 91 Radio FM","UmerKot 91.4 Radio","TMK 100.20 Radio"
};
public static int [] images ={R.drawable.ghotkifmlogo,R.drawable.umerkotfmlogo,R.drawable.tmkfmlogo};
In an custom listview how can I replace these in another Image view and texview?
I need to change that imageview and textview everytime with the clicked item's image and text.
Here's my Custom Adapter:
public class TrackAdapter extends BaseAdapter{
String [] description;
Context context;
int [] imageId;
public TrackAdapter(Context c, String[] d, int[] prgmImages) {
description=d;
context= c;
imageId=prgmImages;
}
@Override
public int getCount() {
return description.length;
}
@Override
public Object getItem(int position) {
return position;
}
@Override
public long getItemId(int position) {
return position;
}
@Override
public View getView(final int position, View convertView, ViewGroup parent) {
if(convertView == null){
convertView = LayoutInflater.from(context).inflate(R.layout.cardviewlayout,null);
}
//get the textview and set its text
TextView tv=(TextView) convertView.findViewById(R.id.tracktitle);
//get the img view and set its img icon
ImageView im=(ImageView) convertView.findViewById(R.id.trackimage);
tv.setText(description[position]);
im.setImageResource(imageId[position]);
return convertView;
}
Here's Main Activity:
private TextView mSelectedTrackTitle;
private ImageView mSelectedTrackImage;
private MediaPlayer mMediaPlayer;
private ImageView mPlayerControl;
ListView lv_tracks;
TrackAdapter track_adapter;
String[] stations = new String[] {
"GHOTKI 91 Radio FM","UmerKot 91.4 Radio","TMK 100.20 Radio"
};
public static int [] images ={R.drawable.ghotkifmlogo,R.drawable.umerkotfmlogo,R.drawable.tmkfmlogo};
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mMediaPlayer = new MediaPlayer();
//get a reference to our ListView so we can associate it with our custom ArrayAdapter
lv_tracks = (ListView) findViewById(R.id.track_list);
//create a new CustomAdapter
track_adapter =new TrackAdapter(this,stations,images);
lv_tracks.setAdapter(track_adapter);//connect the ListView with myCustomAdapter
//Want to set selected image and title here in these
mSelectedTrackTitle = (TextView)findViewById(R.id.selected_track_title);
mSelectedTrackImage =(ImageView)findViewById(R.id.selected_track_image);
lv_tracks.setOnItemClickListener(new AdapterView.OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
??
}
Do not really understand what to do with onitemselect here . in order to change image and text.
you can get current item position by using listview OnItemClickListener it will returns position of an Item clicked then you can use this position as your desired operation
lv_tracks.setOnItemClickListener(new AdapterView.OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
mSelectedTrackTitle.setText(stations[position]);
mSelectedTrackImage.setImageDrawable(ContextCompat.getDrawable(this,images [position]));
// or
mSelectedTrackImage.setImageResource(images [position]);
}
Try something like this
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
mSelectedTrackTitle.setText( stations[position] );
mSelectedTrackImage.setImageResource( images[positions] );
}
It will get the station name and image from the clicked position in your arrays, and update your views.
You can achieve it like this:
lv_tracks.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
mSelectedTrackTitle.setText(stations[position]);
mSelectedTrackImage.setImageResource(images[position]);
}
