i am new to this community just 1-2 weeks ago i came to this community but i am developing 3 apps for a year,i actually want to learn a bit off java,to develop extension.

before starting with my question i would like to thank this wonderfull conversation

Getting error in extension building - Extension Development - MIT App Inventor Community

from where i developed the code a bit
after reffering from android studio
at this para it says the code for positioning:- click here

i made the code with gravity and a new pakage imported

import android.content.Context;
import android.util.Log;
import com.google.appinventor.components.annotations.;

import com.google.appinventor.components.annotations.DesignerComponent;

import android.widget.Toast;
import android.content.Context;
import android.view.Gravity;

@DesignerComponent(version = 1, description = “This Extension was created with the AppyBuilder Code Editor.
” +
“Create your own here:
https://editor.appybuilder.com
”,
category = ComponentCategory.EXTENSION,
nonVisible = true, iconName = “http://appyBuilder.com/extensions/icons/extension.png”)
@SimpleObject(external = true)
public class Simple_toast extends AndroidNonvisibleComponent {
private ComponentContainer container;
/**
* @param container container, component will be placed in
*/
public Simple_toast(ComponentContainer container) {
super(container.$form());
this.container = container;
}

@SimpleFunction(description = “Show toast message,give xaxis,yaxis,message”)
public void ShowToastMessage(String message, int x, int y) {
//YOUR ACTIVITY HERE
Toast toast = Toast.makeText(container.$context(),message,Toast.LENGTH_SHORT);
toast.setGravity(Gravity.CENTER, x, y);
toast.show();
}
@SimpleFunction(description = “Show toast message,give message”)
public void ShowsimpleToastMessage(String message) {
//YOUR ACTIVITY HERE
Toast toast1 = Toast.makeText(container.$context(),message,Toast.LENGTH_SHORT);
toast1.show();
}
}

later i want to add the background colour ,text colour,custom toast (image+text)
but here i have a problem i neither know the packages name i need to import nor the code

To change the Background color use this code.

Toast toast = Toast.makeText(context, Message, Toast.LENGTH_LONG);   
toast.getView().setBackgroundColor(Color.TRANSPARENT);
toast.show();

Imports you need

import android.view.View;
import android.widget.Toast;

You will need to import the Color class as well:
android.graphics.Color.
As you are using one if its enums/constants here:

Note: for questions about extension development, you should ask in the app Inventor community:

The #discuss category is for discussion about kodular.
Thanks.

electrobot_appy · December 28, 2020, 5:38am

ads are not relevant to this topic post it in new topic its not relevant to toast

AryanGupta · December 28, 2020, 6:33am

I think your compiler doesn’t support Android imports

Akshat_Rana · December 28, 2020, 6:34am

so, what should i do?

AryanGupta · December 28, 2020, 6:35am

The code is for extension ?? If yes, then don’t worry it will work in extensions.

Akshat_Rana · December 28, 2020, 6:36am

when i am compiling it shows package does not exist

AryanGupta · December 28, 2020, 6:38am

How you compile the code ?? Do not compile the code in your compiler . Just copy the code and paste it in a new notepad java file and then, save the file to your package. After that you can run ant extensions in Apache ant
