本文实例为大家分享了Android viewflipper实现左右滑动切换显示图片的具体代码,供大家参考,具体内容如下
1.首先定义四个动画文件,表示当view切换的时候的显示效果
in_leftright.xml
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="Http://schemas.android.com/apk/res/android" >
<translate
android:duration="500"
android:fromXDelta="0"
android:toXDelta="-100%p" />
</set>
in_rightleft.xml
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android" >
<translate
android:duration="500"
android:fromXDelta="100%p"
android:toXDelta="0" />
</set>
out_leftright.xml
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android" >
<translate
android:duration="500"
android:fromXDelta="0"
android:toXDelta="100%p" />
</set>
out_rightleft.xml
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android" >
<translate
android:duration="500"
android:fromXDelta="0"
android:toXDelta="-100%p" />
</set>
2.在main.xml中添加ViewFlipper控件,里面放三个LinearLayout,表示3个view
<?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"
android:orientation="vertical" >
<ViewFlipper
android:id="@+id/viewFlipper"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<!-- first page -->
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:gravity="center" >
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:src="@drawable/a001" />
</LinearLayout>
<!-- second page -->
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:gravity="center" >
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:src="@drawable/a002" />
</LinearLayout>
<!-- third page -->
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:gravity="center" >
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:src="@drawable/a003" />
</LinearLayout>
</ViewFlipper>
</LinearLayout>
3.最后在activity里的onTouchEvent事件中,来判断是往哪个方向移动
package org.example.viewflipper;
import android.app.Activity;
import android.os.Bundle;
import android.view.MotionEvent;
import android.widget.ViewFlipper;
public class ViewFlipperActivity extends Activity {
private ViewFlipper viewFlipper = null;
float startX;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
// init widget
viewFlipper = (ViewFlipper) findViewById(R.id.viewFlipper);
}
@Override
public boolean onTouchEvent(MotionEvent event) {
switch (event.getAction()) {
case MotionEvent.ACTION_DOWN:
startX = event.getX();
break;
case MotionEvent.ACTION_UP:
if (event.getX() > startX) {// flip to right
viewFlipper.setInAnimation(this, R.anim.in_leftright);
viewFlipper.setOutAnimation(this, R.anim.out_leftright);
viewFlipper.showNext();
} else {// flip to left
viewFlipper.setInAnimation(this, R.anim.in_rightleft);
viewFlipper.setOutAnimation(this, R.anim.out_rightleft);
viewFlipper.showPrevious();
}
}
return super.onTouchEvent(event);
}
}
--结束END--
