我的代码是
public class ShaderParcelalable implements Parcelable {
public BitmapShader getShader() {
return shader;
}
private BitmapShader shader;
protected ShaderParcelalable(Parcel in) {
this.shader = (BitmapShader) in.readValue(BitmapShader.class.getClassLoader());
}
public ShaderParcelalable(BitmapShader shader) {
this.shader = shader;
}
public static final Creator<ShaderParcelalable> CREATOR = new Creator<ShaderParcelalable>() {
@Override
public ShaderParcelalable createFromParcel(Parcel in) {
return new ShaderParcelalable(in);
}
@Override
public ShaderParcelalable[] newArray(int size) {
return new ShaderParcelalable[size];
}
};
@Override
public int describeContents() {
return 0;
}
@Override
public void writeToParcel(Parcel dest, int flags) {
dest.writeValue(shader);
}
}
答案 0 :(得分:0)
BitmapShader类没有实现Parcelable,因此您不能使用这种方式。 根据您的使用情况,您可以例如保存您需要的参数(重新)创建BitmapShader。对于BitmapShader类,您可以尝试保存
在包裹中。然后,您可以使用此数据重新创建BitmapShader。不是最好的选择,但另一方面,您可能想重新考虑您的架构。
