Wie ändere ich die Höhe der Ansicht im Adapter?

Question

Ich möchte die Höhe der Ansicht ändern und Höhe die gesamte Ansicht von unten verringern. Das funktioniert gut im Fragment, funktioniert aber nicht im Adapter. Ich möchte nicht die Hauptansicht quetschen, ich muss nur die Größe von containerAvatar erhöhen.

public class OrderAdapter extends ArrayAdapter { 

@Override 
public View getView(final int position, View convertView, ViewGroup parent) { 
    LayoutInflater layoutInflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE); 

    convertView = layoutInflater.inflate(R.layout.open_order_item, parent, false); 

    containerAvatar = convertView.findViewById(R.id.container_avatar_size); 
    imgAvatar = convertView.findViewById(R.id.img_open_order_avatar); 

    Glide.with(context) 
      .load("http://neuronovosti.ru/wp-content/uploads/2017/12/Drosophila-Brain-1024x1024.jpg") 
      .into(imgAvatar); 

    containerAvatar.setOnClickListener(new View.OnClickListener() { 
     @Override 
     public void onClick(View view) { 
      final ViewGroup.LayoutParams lp = containerAvatar.getLayoutParams(); 
      final ResizeAnimation a = new ResizeAnimation(containerAvatar); 
      a.setDuration(500); 
      a.setParams(lp.height, lp.height * 2); 
      containerAvatar.startAnimation(a); 
     } 
    }); 

    return convertView; 
} 

public class ResizeAnimation extends Animation { 
    private int startHeight; 
    private int deltaHeight; // distance between start and end height 
    private View view; 

public ResizeAnimation(View v) { 
    this.view = v; 
} 

@Override 
protected void applyTransformation(float interpolatedTime, Transformation t) { 

    view.getLayoutParams().height = (int) (startHeight + deltaHeight * interpolatedTime); 
    view.requestLayout(); 
} 

public void setParams(int start, int end) { 

    this.startHeight = start; 
    deltaHeight = end - startHeight; 
} 

@Override 
public void setDuration(long durationMillis) { 
    super.setDuration(durationMillis); 
} 

@Override 
public boolean willChangeBounds() { 
    return true; 
} 

Das ist, was Sie

brauchen Versuchen mit setLayoutParams() Methode der View -

private void setDimensions(View view, int width, int height){ 
    android.view.ViewGroup.LayoutParams params = view.getLayoutParams(); 
    params.width = width; 
    params.height = height; 
    view.setLayoutParams(params); 
} 

hinzugefügt es auf Ihrem Adapter -

public class OrderAdapter extends ArrayAdapter { 

@Override 
public View getView(final int position, View convertView, ViewGroup parent) { 
    LayoutInflater layoutInflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE); 

    convertView = layoutInflater.inflate(R.layout.open_order_item, parent, false); 

    containerAvatar = convertView.findViewById(R.id.container_avatar_size); 
    imgAvatar = convertView.findViewById(R.id.img_open_order_avatar); 

    Glide.with(context) 
      .load("http://neuronovosti.ru/wp-content/uploads/2017/12/Drosophila-Brain-1024x1024.jpg") 
      .into(imgAvatar); 

    containerAvatar.setOnClickListener(new View.OnClickListener() { 
     @Override 
     public void onClick(View view) { 
      setDimensions(containerAvatar, 100, 100); 
     } 
    }); 

    return convertView; 
} 

private void setDimensions(View view, int width, int height){ 
    android.view.ViewGroup.LayoutParams params = view.getLayoutParams(); 
    params.width = width; 
    params.height = height; 
    view.setLayoutParams(params); 
} 

}
