I Am Just Trying To Create Simple Listview But I Am Not Success Please Help Me
My Java Code
package com.srrazmi.List;
import android.content.Context;
import com.google.appinventor.components.common.ComponentCategory;
import com.google.appinventor.components.annotations.*;
import com.google.appinventor.components.runtime.*;
import android.app.Activity;
import android.content.Intent;
import android.view.View;
import android.widget.ArrayAdapter;
import android.widget.ListView;
import com.google.appinventor.components.common.YaVersion;
import com.google.appinventor.components.runtime.util.ElementsUtil;
import com.google.appinventor.components.runtime.util.YailList;
@DesignerComponent(version = 1, description = "Simple Extension For List",
category = ComponentCategory.EXTENSION,
nonVisible = true, iconName = "http://appyBuilder.com/extensions/icons/extension.png")
@SimpleObject(external = true)
public class List extends AndroidNonvisibleComponent {
private ComponentContainer container;
private Context context; //Added
private Activity activity; //Added
/**
* @param container container, component will be placed in
*/
public List(ComponentContainer container) {
super(container.$form());
this.container = container;
context = (Context) container.$context(); //Added
}
@SimpleFunction(description = "Simple ListView For Learning ")
public void MakeList(YailList list , AndroidViewComponent arragment) {
View view = arragment.getView();
adapter = new ArrayAdapter<Spannable>(container.$context(), android.R.layout.simple_list_item_1,
list);
view.setAdapter(adapter);
}
}
Don’t Suggest Me That List view Is Already Available , Because I Am Just Trying To Learn
