主要是onActivityResult回调如何写

public class ImagePickerModule extends ReactContextBaseJavaModule implements ActivityEventListener {
    public ImagePickerModule(ReactApplicationContext reactContext) {
        super(reactContext);
        reactContext.addActivityEventListener(this);
    }
}
现在我们可以获取到相册返回的数据了。

@Override
public void onActivityResult(final int requestCode, final int resultCode, final Intent intent) {
    if (pickerSuccessCallback != null) {
        if (resultCode == Activity.RESULT_CANCELED) {
            pickerCancelCallback.invoke("ImagePicker was cancelled");
        } else if (resultCode == Activity.RESULT_OK) {
            Uri uri = intent.getData();

            if (uri == null) {
                pickerCancelCallback.invoke("No image data found");
            } else {
                try {
                    pickerSuccessCallback.invoke(uri);
                } catch (Exception e) {
                    pickerCancelCallback.invoke("No image data found");
                }
            }
        }
    }
}
