activity_guide.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout 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:id="@+id/guide"
tools:context="com.example.weijian.homeletterapplication.GuideActivity">
<ViewFlipper
android:id="@+id/Main_ViewFlipper"
android:layout_width="match_parent"
android:layout_height="match_parent" >
</ViewFlipper>
</LinearLayout>

GuideActivity.java

import android.content.Intent;
import android.support.v7.app.ActionBar;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.GestureDetector;
import android.view.MotionEvent;

import android.view.WindowManager;
import android.widget.ImageView;
import android.widget.ViewFlipper;
public class GuideActivity extends AppCompatActivity implements GestureDetector.OnGestureListener {
private GestureDetector detector;
private ViewFlipper flipper;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_guide);
//隐藏标题栏
ActionBar actionBar = getSupportActionBar();
actionBar.hide();
detector = new GestureDetector(this);
flipper = (ViewFlipper) this.findViewById(R.id.Main_ViewFlipper);
flipper.addView(addImageView(R.mipmap.guide1));
flipper.addView(addImageView(R.mipmap.guide2));
flipper.addView(addImageView(R.mipmap.guide3));
}
private View addImageView(int id) {
ImageView iv = new ImageView(this);
//ImageView拉伸，充满整个ViewFlipper
iv.setScaleType(ImageView.ScaleType.FIT_XY);
iv.setImageResource(id);
return iv;
}
@Override

}
@Override

}
@Override

float velocityY) {
if (e1.getX() - e2.getX() > 120) {
this.flipper.showNext();
}
if (e1.getX() - e2.getX() < -120) {
this.flipper.showPrevious();
}
return false;
