package com.example.administrator.myapplication; import android.support.v7.app.ActionBarActivity; import android.os.Bundle; import android.view.MotionEvent; import android.view.View; import android.widget.TextSwitcher; import android.widget.TextView; import android.widget.ViewSwitcher; public class MainActivity2 extends ActionBarActivity implements ViewSwitcher.ViewFactory,View.OnTouchListener {
       private TextSwitcher textSwitcher;     private String[] texts={"岁月是一把无情的杀猪刀","岁月静好，现世安稳","我有钱我任性"};     private int index; //默认为0     @Override     protected void onCreate(Bundle savedInstanceState) {
           super.onCreate(savedInstanceState);         setContentView(R.layout.activity_main2);         textSwitcher= (TextSwitcher) findViewById(R.id.textSwitcher);         textSwitcher.setOnTouchListener(this);         textSwitcher.setFactory(this);     }     @Override     public View makeView() {
           TextView tv=new TextView(this);    tv.setText(texts[index]);         return tv;     }     float startX=0.0f;     float endX=0.0f;     @Override     public boolean onTouch(View v, MotionEvent event) {
           int action=event.getAction();//获取当前的事件动作         System.out.println("action="+action);//sout         if(action==MotionEvent.ACTION_DOWN)         {
               startX=event.getX();             return true;         }         if(action==MotionEvent.ACTION_UP)         {
               endX=event.getX();             if(startX-endX>20)//下一张             {
                   index=(index+1
    
     20){     //上一张                 index=(index-1>=0?--index:texts.length-1);                 // imageSwitcher.setImageResource(images[index]);                 textSwitcher.setInAnimation(this,android.R.anim.fade_in);                 textSwitcher.setOutAnimation(this,android.R.anim.fade_out);             }             System.out.println("index"+index);             textSwitcher.setText(texts[index]);         }         return true;     }     }
    

ImageSwitcher

滑动后

代码：

package com.example.administrator.myapplication; import android.app.Activity; import android.os.Bundle; import android.view.MotionEvent; import android.view.View; import android.widget.ImageSwitcher; import android.widget.ImageView; import android.widget.TextView; import android.widget.ViewSwitcher; public class MainActivity extends Activity implements ViewSwitcher.ViewFactory,View.OnTouchListener{

           ImageView iv=new ImageView(this);         iv.setImageResource(images[0]);         TextView tv=new TextView(this);         tv.setText(texts[index]);         return iv;     }     float startX=0.0f;     float endX=0.0f;     // 触屏事件     @Override     public boolean onTouch(View v, MotionEvent event) {
      int action=event.getAction();//获取当前的事件动作 System.out.println("action="+action);//sout         if(action==MotionEvent.ACTION_DOWN)         {
               startX=event.getX();             return true;         }         if(action==MotionEvent.ACTION_UP)         {
               endX=event.getX();             if(startX-endX>20)//下一张             {
                   index=(index+1
    
     20){     //上一张                 index=(index-1>=0?--index:images.length-1);                // imageSwitcher.setImageResource(images[index]);                 imageSwitcher.setInAnimation(this,android.R.anim.fade_in);                 imageSwitcher.setOutAnimation(this,android.R.anim.fade_out);             }             System.out.println("index"+index);             imageSwitcher.setImageResource(images[index]);         }         return true;     } }
