viewfliper用法基本

viewflipper代码:

public class ViewFlipperActivity extends Activity implements android.view.GestureDetector.OnGestureListener {

private int[] imgs = { R.drawable.img1, R.drawable.img2,
 R.drawable.img3, R.drawable.img4, R.drawable.img5 };


private GestureDetector gestureDetector = null;
private ViewFlipper viewFlipper = null;


private Activity mActivity = null;


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


mActivity = this;


viewFlipper = (ViewFlipper) findViewById(R.id.viewflipper);
gestureDetector = new GestureDetector(this);// 声明检测手势事件


for (int i = 0; i < imgs.length; i++) { // 添加图片源
ImageView iv = new ImageView(this);
iv.setImageResource(imgs[i]);
iv.setScaleType(ImageView.ScaleType.FIT_XY);
viewFlipper.addView(iv, new LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT));
}

viewFlipper.setAutoStart(true);// 设置自动播放功能（点击事件，前自动播放）
viewFlipper.setFlipInterval(1000);
if(viewFlipper.isAutoStart() && !viewFlipper.isFlipping()){
viewFlipper.startFlipping();
}
}


@Override
public boolean onTouchEvent(MotionEvent event) {
viewFlipper.stopFlipping();// 点击事件后，停止自动播放
viewFlipper.setAutoStart(false);
return gestureDetector.onTouchEvent(event); // 注册手势事件
}


@Override
public boolean onFling(MotionEvent e1, MotionEvent e2, float velocityX, float velocityY) {
if (e2.getX() - e1.getX() > 120) {// 从左向右滑动（左进右出）
Animation rInAnim = AnimationUtils.loadAnimation(mActivity, R.anim.push_right_in);// 向右滑动左侧进入的渐变效果（alpha  0.1 -> 1.0）
Animation rOutAnim = AnimationUtils.loadAnimation(mActivity, R.anim.push_right_out); // 向右滑动右侧滑出的渐变效果（alpha 1.0  -> 0.1）


viewFlipper.setInAnimation(rInAnim);
viewFlipper.setOutAnimation(rOutAnim);
viewFlipper.showPrevious();
return true;
} else if (e2.getX() - e1.getX() < -120) {// 从右向左滑动（右进左出）
Animation lInAnim = AnimationUtils.loadAnimation(mActivity, R.anim.push_left_in);// 向左滑动左侧进入的渐变效果（alpha 0.1  -> 1.0）
Animation lOutAnim = AnimationUtils.loadAnimation(mActivity, R.anim.push_left_out);// 向左滑动右侧滑出的渐变效果（alpha 1.0  -> 0.1）


viewFlipper.setInAnimation(lInAnim);
viewFlipper.setOutAnimation(lOutAnim);
viewFlipper.showNext();
return true;
}
return true;
}


@Override
public boolean onDown(MotionEvent e) {
return false;
}


@Override
public void onLongPress(MotionEvent e) {
}


@Override
public boolean onScroll(MotionEvent e1, MotionEvent e2, float distanceX, float distanceY) {
return false;
}


@Override
public void onShowPress(MotionEvent e) {
}


@Override
public boolean onSingleTapUp(MotionEvent e) {
return false;
}

}
