@WatermelonIce, can you please edit the code and change whatever is wrong?
Let me check the source code of HVArrangement first and see how it works 
In HVArrangement:
You need to specify container, orientation and scrollable.
Therefore,
import android.content.Context;
import android.util.Log;
import com.google.appinventor.components.annotations.*;
import com.google.appinventor.components.runtime.*;
import com.google.appinventor.components.common.ComponentCategory;
import com.google.appinventor.components.common.ComponentConstants;
import android.view.View;
@DesignerComponent(version = 1, description = " made by Soham Shah",
category = ComponentCategory.EXTENSION,
nonVisible = true, iconName = "http://yusufcihan.com/img/favicon.png")
@SimpleObject(external = true)
public class DynamicArrangements extends AndroidNonvisibleComponent {
private ComponentContainer container;
/**
* @param container container, component will be placed in
*/
public DynamicArrangements(ComponentContainer container) {
super(container.$form());
this.container = container;
}
@SimpleFunction(description = "Creates a dynamic arrangement in selected arrangement.")
public void CreateArrangement(AndroidViewComponent component) {
new HVArrangement((ComponentContainer)component, LAYOUT_ORIENTATION_HORIZONTAL /*or LAYOUT_ORIENTATION_VERTICAL*/, true //or false depends on scrollable or not)
}
Note
- Constant of orientation:
static final int LAYOUT_ORIENTATION_HORIZONTAL = ComponentConstants.LAYOUT_ORIENTATION_HORIZONTAL; //0
static final int LAYOUT_ORIENTATION_VERTICAL = ComponentConstants.LAYOUT_ORIENTATION_VERTICAL; //1
can you please send the code like you did for below so i can copy and paste
It is from github
You can easily try @yusufcihan source code as i’ve said earlier :
No need to copy all code of the HVArrangement in your extension.Simply import
com.google.appinventor.components.runtime.HVArrangement
Here the output of this constructor ( HVArrangement ) will be better if it was assigned to a variable so you can use later.Something like:
HVArrangement myArrangement = new HVArrangement ( layout,orentationEnum,scrollable );
Well actually I am just showing the code and tell him what should he deals with parameters

I thought you told him that becuase he said send me the code, so you sent him the github link 
.Any way, he still need to import the HVArrangement class, or at least import its parent packagecom.google.appinventor.components.runtime.*; 
Just tested, after removing unnecessary imports in my post 11, it works.

so what do i need to change?
Did you not see my test code…

Also you can see this.It should do it properly

If your project has another name, rename this one:

yes it should be

it works but how can i set width in the same block?
Put this code under the code you create the arrangement with:
hv.Height(myHeight);
