一.当viewpager无法抑制满足循环滑动时,以及需要手势动作时,就用到了viewFlipper

1.代码演示

(1)布局

<?xml version="1.0" encoding="utf-8"?><LinearLayout    xmlns:android="http://schemas.android.com/apk/res/android"    xmlns:app="http://schemas.android.com/apk/res-auto"    xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent"    android:layout_height="match_parent"    tools:context="com.example.my_android_gestrue.MainActivity">    <ViewFlipper        android:layout_width="match_parent"        android:layout_height="match_parent"        android:id="@+id/vf_main_image"        ></ViewFlipper></LinearLayout>

(2)activity

package com.example.my_android_gestrue;import android.support.v7.app.AppCompatActivity;import android.os.Bundle;import android.util.Log;import android.view.GestureDetector;import android.view.MotionEvent;import android.widget.ImageView;import android.widget.Toast;import android.widget.ViewFlipper;public class MainActivity extends AppCompatActivity {    private ViewFlipper vf_main_image;    private int iamges []={R.drawable.s1,R.drawable.s2,R.drawable.s3};    private GestureDetector gd;    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);        vf_main_image = (ViewFlipper) findViewById(R.id.vf_main_image);        for (int i = 0; i < iamges.length; i++) {            ImageView iv=new ImageView(this);            iv.setImageResource(iamges[i]);            vf_main_image.addView(iv);        }        //实例化手势检测器类        //按下,但是还未抬起//轻按,按一下,立刻抬起//滚动//长按//拖动        gd = new GestureDetector(this, new GestureDetector.OnGestureListener() {            @Override            public boolean onDown(MotionEvent motionEvent) {                Log.i("test","onDown");                return false;            }            //按下,但是还未抬起            @Override            public void onShowPress(MotionEvent motionEvent) {                Log.i("test","onShowPress");            }            //轻按,按一下,立刻抬起            @Override            public boolean onSingleTapUp(MotionEvent motionEvent) {                Log.i("test","onSingleTapUp");                return false;            }            //滚动            @Override            public boolean onScroll(MotionEvent motionEvent, MotionEvent motionEvent1, float v, float v1) {                Log.i("test","onScroll");                return false;            }            //长按            @Override            public void onLongPress(MotionEvent motionEvent) {                Log.i("test","onLongPress");            }            //拖动            @Override            public boolean onFling(MotionEvent motionEvent, MotionEvent motionEvent1, float v, float v1) {                Log.i("test","onFling");                if (motionEvent1.getX()-motionEvent.getX()>200){                    Toast.makeText(MainActivity.this, "右滑,下一张", Toast.LENGTH_SHORT).show();                    vf_main_image.showPrevious();                    //左进右出                    vf_main_image.setInAnimation(MainActivity.this,R.anim.left_in);                    vf_main_image.setOutAnimation(MainActivity.this,R.anim.right_out);                }                if (motionEvent.getX()-motionEvent1.getX()>200){                    Toast.makeText(MainActivity.this, "左滑,下一张", Toast.LENGTH_SHORT).show();                    vf_main_image.showPrevious();                    //左出右进                    vf_main_image.setInAnimation(MainActivity.this,R.anim.right_in);                    vf_main_image.setOutAnimation(MainActivity.this,R.anim.left_out);                }                return false;            }        });    }    @Override    public boolean onTouchEvent(MotionEvent event) {        return gd.onTouchEvent(event);    }}

(3)你要设置图片进行怎样的滑动,就新建一个包anim

四个set,xml

A.左滑:

//左出右进left_out.xml(左出)<?xml version="1.0" encoding="utf-8"?><set xmlns:android="http://schemas.android.com/apk/res/android"    android:fillAfter="true"    android:duration="1000"    >    <translate        android:fromXDelta="0"        android:toXDelta="-100%p"        ></translate>    <rotate        android:fromDegrees="0"        android:toDegrees="-360"        android:pivotX="50%"        android:pivotY="50%"        ></rotate></set>

right_in.xml(右进)
<?xml version="1.0" encoding="utf-8"?><set xmlns:android="http://schemas.android.com/apk/res/android"    android:fillAfter="true"    android:duration="1000"    >    <translate        android:fromXDelta="100%p"        android:toXDelta="0"        ></translate>    <rotate        android:fromDegrees="0"        android:toDegrees="-360"        android:pivotX="50%"        android:pivotY="50%"        ></rotate></set>





B.右滑:
  //左进右出left_in.xml(左进)<?xml version="1.0" encoding="utf-8"?><set xmlns:android="http://schemas.android.com/apk/res/android"    android:fillAfter="true"    android:duration="1000"    >    <translate        android:fromXDelta="-100%p"        android:toXDelta="0"        ></translate>    <rotate        android:fromDegrees="0"        android:toDegrees="360"        android:pivotX="50%"        android:pivotY="50%"        ></rotate></set>right_out.xml(右出)<?xml version="1.0" encoding="utf-8"?><set xmlns:android="http://schemas.android.com/apk/res/android"    android:fillAfter="true"    android:duration="1000"    >    <translate        android:fromXDelta="0"        android:toXDelta="100%p"        ></translate>    <rotate        android:fromDegrees="0"        android:toDegrees="360"        android:pivotX="50%"        android:pivotY="50%"        ></rotate></set>

ok,完成了!
