How to use Android ViewSwitcher?

Question

I\'m trying to use the ViewSwitcher to perform switches between two views. One is an ImageView and the other is a MapView. I have a button which the user clicks to perform t

Answer 1

Your ImageView tag should fall under ViewSwitcher tag, just like the com.google.android.maps.MapView.

Answer 2

Are you setting Layout parameters at runtime or is everything in the XML?

Have you tried wrapping the two views of the ViewSwitcher each into its own LinearLayout?

Answer 3

Add the ViewSwitcher widget to your xml layout file. to the ViewSwitcher add 2 new layouts.

<ViewSwitcher
        android:id="@+id/viewSwitcher1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentLeft="true"
        android:layout_alignParentTop="true"
        android:inAnimation="@android:anim/slide_in_left" >

        <LinearLayout
        android:id="@+id/view1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content" >
        <TextView
            android:id="@+id/text"
            android:text="This is simplezdscsdc text"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content">
            </TextView>

        </LinearLayout>


    <LinearLayout
        android:id="@+id/view2"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content" >
        <TextView
            android:id="@+id/text"
            android:text="This issdsdsds simplezdscsdc text"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content">
            </TextView>

        </LinearLayout>
    </ViewSwitcher>

In your activity, add function to a button which switches between the views

viewSwitcher =   (ViewSwitcher)findViewById(R.id.viewSwitcher1);
        myFirstView= findViewById(R.id.view1);
        mySecondView = findViewById(R.id.view2);
        button1 = (Button) findViewById(R.id.button1);
        button1.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View arg0) {
                // TODO Auto-generated method stub
                if (viewSwitcher.getCurrentView() != myFirstView){

                    viewSwitcher.showPrevious(); 
                } else if (viewSwitcher.getCurrentView() != mySecondView){

                    viewSwitcher.showNext();
                }
            }
        });

android:inAnimation="@android:anim/slide_in_left" allows the view to scroll in from the left

Answer 4

You need to have a LinearLayout wrapping everything else. On the example I see more than one but no main one.
