छवि स्लाइड शो उदाहरण एंड्रॉइड में?

Question

मैं एंड्रॉइड में छवि स्लाइड शो बनाना चाहता हूं।

मेरे पास एंड्रॉइड ग्रिड व्यू में कई छवियां हैं, यदि मैं किसी भी छवि पर क्लिक किया गया है तो मैन्युअल स्लाइड शो खोलना चाहता हूं ताकि मैं गैलरी में निर्मित एंड्रॉइड की तरह अगली और पिछली छवियों पर उंगली को बाएं या दाएं स्थानांतरित करके देख सकूं।

कोई भी मुझे यह कैसे प्राप्त करने के लिए मार्गदर्शन करता है?

किसी भी मदद की सराहना की जाएगी।

Answer 1

आप ApiDemos में Gallery1 और Gallery2 का उदाहरण देख सकते हैं:

Answer 2

आप ViewFlipper उपयोग कर रहे हैं छवियों

slideShowBtn.setOnClickListener(new OnClickListener() { 

      @Override 
      public void onClick(View arg0) { 

       runnable = new Runnable() { 

        @Override 
        public void run() { 
         handler.postDelayed(runnable, 3000); 
         imageFrame.showNext(); 

        } 
       }; 
       handler.postDelayed(runnable, 500); 
      } 
     }); 

प्रदर्शित करने के लिए इस कोड का प्रयास करें इसका इस्तेमाल को रोकने के लिए handler.removeCallbacks(runnable);

Answer 3

यह एंड्रॉयड में ViewFlipper का उपयोग कर स्लाइड शो लागू करने के लिए बहुत आसान है।

छवियों को खींचने योग्य फ़ोल्डर में डाल दें और नीचे दिए गए कोड का पालन करें।

slide_show.xml

<?xml version="1.0" encoding="utf-8"?> 
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    android:orientation="vertical" > 

    <ViewFlipper 
     android:id="@+id/myflipper" 
     android:layout_width="fill_parent" 
     android:layout_height="fill_parent" 
     android:gravity="center" > 
    </ViewFlipper> 

</LinearLayout> 

SlideShowActivity.java

package com.example.viewpagerexample; 

import android.app.Activity; 
import android.os.Bundle; 
import android.view.MotionEvent; 
import android.widget.ImageView; 
import android.widget.ViewFlipper; 

public class SlideShowActivity extends Activity { 

    private ViewFlipper myViewFlipper; 
    private float initialXPoint; 
    int[] image = { R.drawable.one_full, R.drawable.two_full, 
     R.drawable.three_full, R.drawable.four_full, R.drawable.five_full, 
     R.drawable.six_full, R.drawable.seven_full, R.drawable.eight_full, 
     R.drawable.nine_full, R.drawable.ten_full }; 

    @Override 
    protected void onCreate(Bundle savedInstanceState) { 

    super.onCreate(savedInstanceState); 
    setContentView(R.layout.slide_show); 
    myViewFlipper = (ViewFlipper) findViewById(R.id.myflipper); 

    for (int i = 0; i < image.length; i++) { 
     ImageView imageView = new ImageView(SlideShowActivity.this); 
     imageView.setImageResource(image[i]); 
     myViewFlipper.addView(imageView); 
    } 
    } 

    @Override 
    public boolean onTouchEvent(MotionEvent event) { 
    switch (event.getAction()) { 
    case MotionEvent.ACTION_DOWN: 
     initialXPoint = event.getX(); 
     break; 
    case MotionEvent.ACTION_UP: 
     float finalx = event.getX(); 
     if (initialXPoint > finalx) { 
      if (myViewFlipper.getDisplayedChild() == image.length) 
       break; 
      myViewFlipper.showNext(); 
     } else { 
      if (myViewFlipper.getDisplayedChild() == 0) 
       break; 
      myViewFlipper.showPrevious(); 
     } 
     break; 
    } 
    return false; 
    } 
} 

यहां छवियों केवल बदल रहे हैं उपयोगकर्ता कड़ी चोट है, जबकि।

आप कुछ अंतराल के साथ स्वचालित रूप से स्वाइप निम्नलिखित कोड

myViewFlipper.setAutoStart(true); 
myViewFlipper.setFlipInterval(3000); 
myViewFlipper.startFlipping();
