android ViewFlipper(翻轉視圖) 使用

一、佈局文件

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" android:paddingBottom="@dimen/activity_vertical_margin" android:paddingLeft="@dimen/activity_horizontal_margin" android:paddingRight="@dimen/activity_horizontal_margin" android:paddingTop="@dimen/activity_vertical_margin" tools:context="com.example.helloword.FlipperActivity" > <ViewFlipper android:id="@+id/flipper" android:layout_width="wrap_content" android:layout_height="wrap_content"></ViewFlipper> </RelativeLayout>

二、drawable 圖片

 

三、Activity：

package com.example.helloword; import android.app.Activity; import android.os.Bundle; import android.view.GestureDetector; import android.view.MotionEvent; import android.view.View; import android.view.animation.Animation; import android.view.animation.AnimationUtils; import android.widget.ImageView; import android.widget.ViewFlipper; public class FlipperActivity extends Activity implements View.OnClickListener, GestureDetector.OnGestureListener{ final int distance = 50; private Animation[] animations = new Animation[4]; private int[] images = new int[]{ R.drawable.img0,R.drawable.img1,R.drawable.img2,R.drawable.img3, R.drawable.img4 }; private ViewFlipper flipper ; private GestureDetector detector; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_flipper); detector = new GestureDetector(FlipperActivity.this,this); flipper = findViewById(R.id.flipper); for (int i = 0; i < images.length; i++) { ImageView img = new ImageView(this); img.setImageResource(images[i]); flipper.addView(img); } animations[0] = AnimationUtils.loadAnimation(this, R.anim.abc_slide_in_bottom); animations[1] = AnimationUtils.loadAnimation(this, R.anim.abc_slide_out_bottom); animations[2] = AnimationUtils.loadAnimation(this, R.anim.abc_slide_in_top); animations[3] = AnimationUtils.loadAnimation(this, R.anim.abc_slide_out_bottom); } @Override public void onPointerCaptureChanged(boolean hasCapture) { // TODO Auto-generated method stub  } @Override public void onClick(View arg0) { // TODO Auto-generated method stub  } @Override public boolean onDown(MotionEvent arg0) { // TODO Auto-generated method stub return false; } @Override public boolean onFling(MotionEvent arg0, MotionEvent arg1, float arg2, float arg3) { if(arg0.getY()-arg1.getY()>distance){ flipper.setInAnimation(animations[2]); flipper.setOutAnimation(animations[1]); flipper.showPrevious(); return true; }else if(arg1.getY()-arg0.getY()>distance){ flipper.setInAnimation(animations[0]); flipper.setOutAnimation(animations[3]); flipper.showNext(); return true; } return false; } @Override public void onLongPress(MotionEvent arg0) { // TODO Auto-generated method stub  } @Override public boolean onScroll(MotionEvent arg0, MotionEvent arg1, float arg2, float arg3) { // TODO Auto-generated method stub return false; } @Override public void onShowPress(MotionEvent arg0) { // TODO Auto-generated method stub  } @Override public boolean onSingleTapUp(MotionEvent arg0) { // TODO Auto-generated method stub return false; } @Override public boolean onTouchEvent(MotionEvent event) { // TODO Auto-generated method stub return detector.onTouchEvent(event); } }
