こんにちは私は次のようにViewFlipperを作成しています。
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="@android:color/white"
android:orientation="vertical" >
<ViewFlipper
android:id="@+id/vfShow"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
</ViewFlipper>
</LinearLayout>
そして、次のようなイベントの処理
ViewFlipperSampleActivity.java
public class ViewFlipperSampleActivity extends Activity {
private static final int SWIPE_MIN_DISTANCE = 120;
private static final int SWIPE_THRESHOLD_VELOCITY = 200;
private ViewFlipper vf;
private Context mContext;
private final GestureDetector detector = new GestureDetector(
new MyGestureDetector());
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.fliper);
mContext = this;
vf = (ViewFlipper) this.findViewById(R.id.vfShow);
vf.setOnTouchListener(new OnTouchListener() {
@Override
public boolean onTouch(final View view, final MotionEvent event) {
detector.onTouchEvent(event);
return true;
}
});
vf.addView(addImageView(R.drawable.a));
vf.addView(addImageView(R.drawable.b));
vf.addView(addImageView(R.drawable.c));
vf.addView(addImageView(R.drawable.d));
}
View addImageView(int resId) {
ImageView iv = new ImageView(this);
iv.setImageResource(resId);
return iv;
}
class MyGestureDetector extends SimpleOnGestureListener {
@Override
public boolean onFling(MotionEvent e1, MotionEvent e2, float velocityX,
float velocityY) {
try {
// right to left swipe
if (e1.getX() - e2.getX() > SWIPE_MIN_DISTANCE
&& Math.abs(velocityX) > SWIPE_THRESHOLD_VELOCITY) {
vf.setInAnimation(AnimationUtils.loadAnimation(mContext,
R.anim.left_in));
vf.setOutAnimation(AnimationUtils.loadAnimation(mContext,
R.anim.left_out));
vf.showNext();
return true;
} else if (e2.getX() - e1.getX() > SWIPE_MIN_DISTANCE
&& Math.abs(velocityX) > SWIPE_THRESHOLD_VELOCITY) {
vf.setInAnimation(AnimationUtils.loadAnimation(mContext,
R.anim.right_in));
vf.setOutAnimation(AnimationUtils.loadAnimation(mContext,
R.anim.right_out));
vf.showPrevious();
return true;
}
} catch (Exception e) {
e.printStackTrace();
}
return false;
}
}
}
今、私はビューフリッパーで特定の画像でサウンドを再生する方法を混乱させていますか？これに関して私を助けてください。
ありがとう
