What is the alternative in Harmony OS for shadow in TextView Android?

In Harmony OS, due to differences in system architecture and design compared to Android, some common UI components and features may require different implementations.

For the shadow effect of the TextView component in Android, Harmony OS provides alternative methods to achieve similar visual effects.

In Harmony OS, you can display text using the Text component and utilize the Shadow property to create shadow effects. The Shadow property allows developers to set the shadow color, offset, and blur radius to achieve the desired visual effect.

Example Code:

java
import ohos.aafwk.ability.AbilitySlice;
import ohos.aafwk.content.Intent;
import ohos.agp.components.AttrSet;
import ohos.agp.components.Text;
import ohos.agp.components.element.ShapeElement;
import ohos.agp.utils.Color;
import ohos.agp.utils.TextAlignment;
import ohos.app.Context;

public class MainAbilitySlice extends AbilitySlice {
    @Override
    public void onStart(Intent intent) {
        super.onStart(intent);

        Text text = new Text(this);
        text.setText("Hello Harmony");
        text.setTextSize(50);
        text.setTextColor(Color.BLACK);
        text.setTextAlignment(TextAlignment.CENTER);
        
        // Set shadow
        text.setShadow(5, 10, 10, Color.GRAY.getValue());

        super.setUIContent(text);
    }
}

In this example, the parameters of the setShadow method are the blur radius, horizontal offset, vertical offset, and shadow color. This achieves a similar shadow effect to that of the TextView in Android.

Summary:

By using the Text component and Shadow property in Harmony OS, you can easily add shadows to text, achieving comparable interface effects to the TextView shadow in Android. This approach not only delivers excellent visual appeal but also ensures consistency in UI component functionality across different operating systems.
