Java – long press is not applicable to listview
•
Java
I'm trying to set up a long press listener for listview:
final ListView gallery=(ListView)findViewById(R.id.dialogViewImagesList); gallery.setLongClickable(true); gallery.setOnLongClickListener(new OnLongClickListener() { @Override public boolean onLongClick(View arg0) { Log.e("event","long"); return true; } }); gallery.setAdapter(new PointImagesAdapter(bitmaps));
This is my adapter:
private class PointImagesAdapter extends ArrayAdapter<Bitmap> { private static final int LAYOUT_ID=R.layout.adapter_point_images; private List<Bitmap> bitmaps; private LayoutInflater inflater; public PointImagesAdapter(List<Bitmap> bitmaps) { super(MainActivity.this,LAYOUT_ID,bitmaps); this.bitmaps=bitmaps; inflater=LayoutInflater.from(MainActivity.this); } @Override public View getView(int position,View view,ViewGroup group) { if (view==null) { view=inflater.inflate(LAYOUT_ID,null); } ImageView i=(ImageView)view.findViewById(R.id.adapterPointImagesItem); i.setScaleType(ImageView.ScaleType.CENTER); i.setImageBitmap(bitmaps.get(position)); view.setFocusable(false); return view; } }
I tried setting view Setlongclickable (true), but in this case, the listview item is not clickable (simple clicking does not work) It is the layout code of the adapter:
<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" android:focusable="false" android:orientation="vertical" > <ImageView android:focusable="false" android:layout_gravity="center" android:layout_marginTop="5dip" android:id="@+id/adapterPointImagesItem" android:layout_width="match_parent" android:layout_height="match_parent" /> </LinearLayout>
I don't understand why this code doesn't work! How can I solve it?
Solution
You must use setonitemlongclicklistener
gallery.setOnItemLongClickListener(new OnItemLongClickListener() { @Override public boolean onItemLongClick(AdapterView<?> arg0,View arg1,final int arg2,long arg3) { }); }
In addition, if the adapter of listview is extended from baseadapter, you also need to set convertview setLongClickable(true); In getview()
