如何解决错误：不是语句flipper.setInAnimationcontext：this，android.R.anim.slide_in_left;

public class MainActivity extends AppCompatActivity {

    ViewFlipper flipper;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);


        int imgarray[] = {
            R.drawable.slide1,R.drawable.slide2,R.drawable.slide3
        };
        flipper = (ViewFlipper) findViewById(R.id.flipper);


        for (int i = 0; i < imgarray.length; i++)
            showimage(imgarray[i]);
    }

    public void showimage(int img) {
        ImageView imageView = new ImageView(context: this);
        imageView.setBackgroundResource(img);
        flipper.addView(imageView);
        flipper.setFlipInterval(3000);
        flipper.setAutoStart(true);
        flipper.setInAnimation(context: this,android.R.anim.slide_in_left);
        flipper.setoutAnimation(context: this,android.R.anim.slide_out_right);
    }

}
