Hi
I am adding ImageViews programatically, but the images can barely drag. it require very long press, sometimes it works and sometimes doesn't.
this is the adding function
private void appendImageToLinearLayout(DragLinearLayout layout, ParseFile parseFileImage, int w, int h, boolean fullWidth, boolean isPostImage, final int position) throws ParseException, IOException { ImageView imageView= new ImageView(this); //imageView.setBackgroundResource(R.drawable.ic_action_search); imageView.setImageBitmap( ImageTools. getBitmapFromUri(Uri.fromFile( parseFileImage.getFile()), this, fullWidth ) ); // params //DragLinearLayout.LayoutParams viewParamsCenter = new DragLinearLayout.LayoutParams( w, h); //viewParamsCenter.gravity = Gravity.CENTER_HORIZONTAL | Gravity.RIGHT; //imageView.setLayoutParams(viewParamsCenter); imageView.setId(position); imageView.setContentDescription(imageList.get(position).getObjectId()); layout.addDragView(imageView, imageView); //layout.setViewDraggable(imageView, imageView); if(isPostImage){ imageView.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { //showImageFullScreen(position); Toast.makeText(EditPostActivity.this, "clicked " + v.getId(), Toast.LENGTH_SHORT).show(); } }); } }
<ScrollView android:id="@+id/llCanvusContainer" android:layout_width="0dp" android:layout_height="0dp" android:layout_marginTop="8dp" android:background="@android:color/white" app:layout_behavior="@string/appbar_scrolling_view_behavior" app:layout_constraintBottom_toBottomOf="parent" app:layout_constraintEnd_toEndOf="parent" app:layout_constraintStart_toStartOf="parent" app:layout_constraintTop_toBottomOf="@+id/switchIsPublic"> <com.jmedeisis.draglinearlayout.DragLinearLayout android:id="@+id/llCanvus" style="@style/Gallery19crollbarStyle" android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_marginTop="16dp" app:layout_constraintBottom_toBottomOf="parent" app:layout_constraintEnd_toEndOf="parent" app:layout_constraintStart_toStartOf="parent" app:layout_constraintTop_toBottomOf="@+id/switchIsPublic" /> </ScrollView>
The images show correctly, but the dragging doesn't work correctly.
the drag and drop works fine when I remove the ScrollView
