Knowledge Base - Wrapped Content Editbox in Android

If you want your Editbox annotation to be wrap content instead of having fixed width and height, you need to modify com.radaee.util.PopupEditAct:

  • Setting layout params with WRAP_CONTENT instead of fixed width and height.
  • Adding a listener to pass the new dimensions to the annotation.

Note: this implementation does not handle the case of the new annotation's dimension may override other page content.

In onEditAnnot in com.Radaee.reader.PDFLayoutView, implement the created listener as follows:

@Override
public void onSizeChanged(int w, int h) {
if(m_annot != null) {
float[] rect = m_annot.GetRect();
m_annot.SetRect(rect[0], rect[3] - (h / m_layout.vGetScale()), rect[0] + (w / m_layout.vGetScale()), rect[3]);
}
}
