Question

I wrote a small test program for flipperview. I have 3 views. I call startFlipping() to bring in the next view, so it goes from the first view, second, 3rd and back to the first

Is thee a way that instead of going to the next view, I could have flipper go directly to any of the 3 different views???

If not, is there a way to hide a vertical container? Maybe I could have 3 vertical containers, have 2 hidden and one shown?

code:

public class TestviewflipperActivity extends Activity implements
    OnClickListener{
    /** Called when the activity is first created. */
    ViewFlipper mFlipper;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        // add listeners
        View mButA = findViewById(R.id.flipbut);
        mButA.setOnClickListener(this);

        mFlipper = (ViewFlipper)findViewById(R.id.flipper);


        View mBut = findViewById(R.id.back_btna);
        mBut.setOnClickListener(this);


    }



    public void onClick(View v) {

mFlipper.startFlipping();   
    }
}

and the layout:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"

Answer 1

You should be able to use mFlipper.setDisplayedChild(int whichChild) to make it filp to the view you desire in your code. The method is defined in ViewFlipper‘s parent, ViewAnimator.
