ViewFlipper左右滑动事件

ViewFlipper左右滑动事件

新建一个继承Activity类的ViewFlipperActivity，并设置布局文件为：viewflipper.xml。

首先在布局文件中添加一个TextView，和一个ViewFlipper，并在ViewFlipper布局中添加2个LinearLayout,里面设置不同的背景颜色。

xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"     android:layout_width="match_parent"     android:layout_height="match_parent"     android:orientation="vertical" >       <TextView         android:id="@+id/viewflipper_tv01"         android:layout_width="wrap_content"         android:layout_height="wrap_content"         android:layout_gravity="center_horizontal"         android:text="@string/show_information"         android:textSize="22sp" />       <ViewFlipper         android:id="@+id/viewflipper_viewflipper"         android:layout_width="match_parent"         android:layout_height="match_parent" >           <LinearLayout             android:layout_width="match_parent"             android:layout_height="match_parent"             android:background="#FFFF0000" >         LinearLayout>           <LinearLayout             android:layout_width="match_parent"             android:layout_height="match_parent"             android:background="#FF0000FF" >         LinearLayout>     ViewFlipper>   LinearLayout>

而后在Activity代码中，获取ViewFlipper对象，并通过onTouchListener()处理ViewFlipper显示的界面。

package lyx.feng.simpletextdemo; ...... public class ViewFlipperActivity extends Activity implements OnTouchListener {     private ViewFlipper viewFlipper = null;     private TextView tv = null;       @Override     protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        super.setContentView(R.layout.viewflipper);        this.viewFlipper = (ViewFlipper) super               .findViewById(R.id.viewflipper_viewflipper);        this.tv = (TextView) super.findViewById(R.id.viewflipper_tv01);        this.viewFlipper.setOnTouchListener(this);         this.viewFlipper.setInAnimation(AnimationUtils.loadAnimation(this,               android.R.anim.fade_in));         this.viewFlipper.setOutAnimation(AnimationUtils.loadAnimation(this,               android.R.anim.fade_out));     }       @Override     public boolean onTouch(View v, MotionEvent event) {        int start = 0;        int end = 0;        switch (event.getAction()) {        case MotionEvent.ACTION_DOWN:            start = (int) event.getX();            break;        case MotionEvent.ACTION_UP:            end = (int) event.getX();            if (start - end > 10) {               this.viewFlipper.showNext();               this.tv.setText("next");               // Toast.makeText(this, "next", Toast.LENGTH_SHORT).show();            }            if (start - end < 10) {               this.viewFlipper.showPrevious();               this.tv.setText("previous");               // Toast.makeText(this, "previous", Toast.LENGTH_SHORT).show();            }            break;        }        return true;     } }
