ImageSwitcher:
activity_main.xml
<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.imageswitch.MainActivity" > <ImageSwitcher android:id="@+id/imageSwitcher1_1" android:layout_width="match_parent" android:layout_height="match_parent" android:layout_alignParentTop="true" > </ImageSwitcher> </RelativeLayout> <!-- android:inAnimation="@android:anim/slide_in_left" android:outAnimation="@android:anim/slide_out_right" -->
MianActivity
package com.example.imageswitch; import android.app.Activity; import android.os.Bundle; import android.view.Menu; import android.view.MenuItem; import android.view.MotionEvent; import android.view.View; import android.view.View.OnTouchListener; import android.widget.ImageSwitcher; import android.widget.ImageView; import android.widget.ViewSwitcher.ViewFactory; public class MainActivity extends Activity implements ViewFactory ,OnTouchListener{ private ImageSwitcher imageSwitch; private int [] images={ R.drawable.kobe0, R.drawable.kobe1, R.drawable.kobe3, R.drawable.kobe4, R.drawable.kobe6, }; private int index; //要显示的图片的下标 @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); imageSwitch=(ImageSwitcher) findViewById(R.id.imageSwitcher1_1); //设置创建ImageView的工厂 imageSwitch.setFactory(this); //设置触屏事件 imageSwitch.setOnTouchListener(this); } //ViewFactory工厂接口的方法,通过这个方法,给ImageSwitch组件提供两个 @Override public View makeView() { // TODO Auto-generated method stub ImageView imageView=new ImageView(this); imageView.setImageResource(images[0]); return imageView; } //定义两个x坐标点 float startx=0.0F; //开始位置 float endx=0.0F; //结束位置 //触屏事件监听方法 @Override public boolean onTouch(View v, MotionEvent event) { if(event.getAction()==MotionEvent.ACTION_DOWN){ startx=event.getX(); return true; }else if(event.getAction()==MotionEvent.ACTION_UP){ endx=event.getX(); //判断左滑动 if(startx-endx>20){ index=(index+1)<(images.length-1)?++index:0; imageSwitch.setImageResource(images[index]); //在代码中设置动画效果 imageSwitch.setInAnimation(this, android.R.anim.fade_in); imageSwitch.setOutAnimation(this, android.R.anim.fade_out); } //判断右滑动 if(endx-startx>20){ index=(index-1)>0?--index:images.length-1; imageSwitch.setImageResource(images[index]); imageSwitch.setInAnimation(this, android.R.anim.slide_in_left); imageSwitch.setOutAnimation(this, android.R.anim.slide_out_right); } } return true; } }
TextSwitcher与ImageSwitcher类似,只需要将ImageSwitcher换成TextSwitcher
设置图片资源修改为设置文本即可
