React native: Is it possible to get react native componet size in Java?
0
I have created custom native component as below for Android's ImageView.
public class ImageViewManager extends SimpleViewManager<ImageView> {
public static final String REACT_CLASS = "ImageView";
@Override
public String getName() {
return REACT_CLASS;
}
@Override
protected ImageView createViewInstance(ThemedReactContext reactContext) {
ImageView imageView = new ImageView(reactContext);
imageView.setLayoutParams(new GridView.LayoutParams(300, 200))
return imageView;
}
@ReactProp(name="src")
public void setSrc(ImageView imageView, String src) {
try {
Bitmap bm = ImageUtilConverter.convert(src); // base64 to bitmap
imageView.setImageBitmap(bm);
} catch(IllegalArgumentException e) {
}
}
}
In JavaScript:
import ImageView from './ImageView'
<ImageView
style={{width: deviceWidth, height: deviceHeight}}
src={this.state.selected} // base64 data
/>
Now I want to get height and width of the component in Java, so that I can set height and width in imageView.setLayoutParams(new GridView.LayoutParams(300, 200)).
Is it possible to get component size in Java?
