嗨，我在我的活动中创建了一个翻转视图我有 2 个需要翻转的图像，但它不是代表翻转我只能在屏幕上查看我的第一个图像......我在下面给出我的类文件和 xml。 . 我需要一些解决方案
import android.app.Activity;
import android.os.Bundle;
import android.view.MotionEvent;
import android.widget.ViewFlipper;
public class Viewflip extends Activity
{
private ViewFlipper viewFlipper;
private float lastX;
@Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.gallery);
viewFlipper = (ViewFlipper) findViewById(R.id.view_flipper);
}
// Method to handle touch event like left to right swap and right to left swap
public boolean onTouchEvent(MotionEvent touchevent)
{
switch (touchevent.getAction())
{
// when user first touches the screen to swap
case MotionEvent.ACTION_DOWN:
{
lastX = touchevent.getX();
break;
}
case MotionEvent.ACTION_UP:
{
float currentX = touchevent.getX();
// if left to right swipe on screen
if (lastX < currentX)
{
// If no more View/Child to flip
if (viewFlipper.getDisplayedChild() == 0)
break;
// set the required Animation type to ViewFlipper
// The Next screen will come in form Left and
current Screen will go OUT from Right
viewFlipper.setInAnimation(this,
R.anim.in_from_left);
viewFlipper.setOutAnimation(this,
R.anim.out_to_right);
// Show the next Screen
viewFlipper.showNext();
}
// if right to left swipe on screen
if (lastX > currentX)
{
if (viewFlipper.getDisplayedChild() == 1)
break;
// set the required Animation type to ViewFlipper
// The Next screen will come in form Right and
current Screen will go OUT from Left
viewFlipper.setInAnimation(this,
R.anim.in_from_right);
viewFlipper.setOutAnimation(this,
R.anim.out_to_left);
// Show The Previous Screen
viewFlipper.showPrevious();
}
break;
}
}
return false;
}
}
