Erhalten Sie doppelte Zeilen in der Listenansicht in Android ⇐ Java

[Guest]

Ich arbeite an einer Listenansicht, die Daten von einem Webdienst auffüllt. Ich erhalte vollständige Ergebnisse gemäß den erforderlichen Ergebnissen vom Webdienst in JSON, aber wenn ich sie im Adapter in der Listenansicht einstelle, erhalte ich nur doppelte Zeilen, was ich auch getan habe Habe meine Arrayliste überprüft, die perfekt ist.

Code: Select all

public class ListingAdapter extends BaseAdapter {
private Activity mContext;
ArrayList busList;

public ListingAdapter(Activity c, ArrayList busList) {
mContext = c;
this.busList = busList;
}

@Override
public int getCount() {
// TODO Auto-generated method stub
return busList.size();
}

@Override
public Object getItem(int position) {
// TODO Auto-generated method stub
return null;
}

@Override
public long getItemId(int position) {
// TODO Auto-generated method stub
return 0;
}

@Override
public View getView(final int position, View convertView, ViewGroup parent) {
// TODO Auto-generated method stub
View grid;
LayoutInflater inflater = (LayoutInflater) mContext.getLayoutInflater();

if (convertView == null) {

grid = new View( mContext );
grid = inflater.inflate( R.layout.raw_tab, null );
TextView tv_cat = (TextView) grid.findViewById( R.id.tv_cat );
ImageView iv_pic = (ImageView) grid.findViewById( R.id.iv_pic );
TextView tv_features = (TextView) grid.findViewById( R.id.tv_features );
TextView tv_location = (TextView) grid.findViewById( R.id.tv_location );
TextView tv_rating = (TextView) grid.findViewById( R.id.tv_rating );
RatingBar rt_bar = (RatingBar) grid.findViewById( R.id.rt_fvrt );
TextView tv_votes = (TextView) grid.findViewById( R.id.tv_votes );
ImageView iv_call = (ImageView) grid.findViewById( R.id.iv_call );
ImageView iv_share = (ImageView) grid.findViewById( R.id.iv_share );

tv_cat.setText( busList.get( position ).getBiz_name() );
tv_features.setText( busList.get( position ).getFeatures() );
tv_location.setText( busList.get( position ).getCity() );
tv_rating.setText( busList.get( position ).getAverage_rate() );
tv_votes.setText( busList.get( position ).getVotes() );
rt_bar.setRating( Float.parseFloat( busList.get( position ).getAverage_rate() ) );
if(!busList.get( position ).getImg_1().equals( "" )){
Picasso.with( mContext )
.load( busList.get( position ).getImg_1().replaceAll(" ", "%20") )
.placeholder( R.drawable.ic_no_img )
.error( R.drawable.ic_no_img )
.into( iv_pic );
}

iv_call.setOnClickListener( new View.OnClickListener() {
@Override
public void onClick(View v) {

Intent intent = new Intent( Intent.ACTION_CALL );

intent.setData( Uri.parse( "tel:" + (busList.get( position ).getMobile_1()) ) );
if (ActivityCompat.checkSelfPermission( mContext, Manifest.permission.CALL_PHONE ) != PackageManager.PERMISSION_GRANTED) {
// TODO: Consider calling
//    ActivityCompat#requestPermissions
// here to request the missing permissions, and then overriding
//   public void onRequestPermissionsResult(int requestCode, String[] permissions,
//                                          int[] grantResults)
// to handle the case where the user grants the permission.  See the documentation
// for ActivityCompat#requestPermissions for more details.
return;
}
mContext.startActivity( intent );
}
} );

iv_share.setOnClickListener( new View.OnClickListener() {
@Override
public void onClick(View v) {
Intent sharingIntent = new Intent( Intent.ACTION_SEND );
sharingIntent.setType( "text/html" );
sharingIntent.putExtra( android.content.Intent.EXTRA_TEXT, Html.fromHtml( "TEst From all About City." ) );
mContext.startActivity( Intent.createChooser( sharingIntent, "Share using" ) );

grid = (View) convertView;
