    text
    copied!<p>I have a list view. On click of an item a detailed view for the item is open. This layout has many widgets like text view, <code>ImageView Buttons</code> etc. Now I want to slide this detail view of the items to show the detail view of next item in the list. Similarly previous item for left to right.</p> <p>I am not able to implement the view sliding I have done how to get the prev / next items in the list. But the actual sliding is the issue </p> <p>I tried gesturedetector like in <a href="https://stackoverflow.com/questions/7198587/android-swipe-left-to-right-and-right-to-left">Android: Swipe left to right and right to left</a> </p> <p>and some other examples. But when I try to slide, there is no effect. I don't see any visual sliding at all.</p> <p>How to fix this?</p> <p>Tried this code but still no slide happening</p> <pre><code> public class ProductActivity extends Activity implements OnGestureListener { @ Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.product_details); setContent(); } private void setContent() { Bundle extras = getIntent().getExtras(); TextView title = (TextView) findViewById(R.id.title); title.setText(extras.getString("Title")); TextView desc = (TextView) findViewById(R.id.desc); desc.setText(extras.getString("Desc")); Button buy = (Button) findViewById(R.id.buy); String priceTag = ("$" + String.format("%.2g", extras.getDouble("Price")) + " Buy Now &gt;&gt;"); buy.setText(priceTag); ImageView image = (ImageView) findViewById(R.id.productimage); Utils.imageLoader.DisplayImage(extras.getString("Image"), image); } private static final int SWIPE_MIN_DISTANCE = 6; // 120; private static final int SWIPE_MAX_OFF_PATH = 125; // 250; private static final int SWIPE_THRESHOLD_VELOCITY = 100; // 200; private GestureDetector gestureScanner; @ Override public boolean onTouchEvent(MotionEvent me) { return gestureScanner.onTouchEvent(me); } // @Override public boolean onDown(MotionEvent e) { // viewA.setText("-" + "DOWN" + "-"); return true; } // @Override public boolean onFling(MotionEvent e1, MotionEvent e2, float velocityX, float velocityY) { try { if (Math.abs(e1.getY() - e2.getY()) &gt; SWIPE_MAX_OFF_PATH) return false; // right to left swipe if (e1.getX() - e2.getX() &gt; SWIPE_MIN_DISTANCE &amp;&amp; Math.abs(velocityX) &gt; SWIPE_THRESHOLD_VELOCITY) { Toast.makeText(getApplicationContext(), "Left Swipe", Toast.LENGTH_SHORT).show(); } else if (e2.getX() - e1.getX() &gt; SWIPE_MIN_DISTANCE &amp;&amp; Math.abs(velocityX) &gt; SWIPE_THRESHOLD_VELOCITY) { Toast.makeText(getApplicationContext(), "Right Swipe", Toast.LENGTH_SHORT).show(); } else if (e1.getY() - e2.getY() &gt; SWIPE_MIN_DISTANCE &amp;&amp; Math.abs(velocityX) &gt; SWIPE_THRESHOLD_VELOCITY) { Toast.makeText(getApplicationContext(), "Swipe up", Toast.LENGTH_SHORT).show(); } else if (e2.getY() - e1.getY() &gt; SWIPE_MIN_DISTANCE &amp;&amp; Math.abs(velocityX) &gt; SWIPE_THRESHOLD_VELOCITY) { Toast.makeText(getApplicationContext(), "Swipe down", Toast.LENGTH_SHORT).show(); } } catch (Exception e) { // nothing } return true; } @ Override public void onLongPress(MotionEvent e) { Toast mToast = Toast.makeText(getApplicationContext(), "Long Press", Toast.LENGTH_SHORT); mToast.show(); } // @Override public boolean onScroll(MotionEvent e1, MotionEvent e2, float distanceX, float distanceY) { // viewA.setText("-" + "SCROLL" + "-"); return true; } // @Override public void onShowPress(MotionEvent e) { // viewA.setText("-" + "SHOW PRESS" + "-"); } // @Override public boolean onSingleTapUp(MotionEvent e) { Toast mToast = Toast.makeText(getApplicationContext(), "Single Tap", Toast.LENGTH_SHORT); mToast.show(); return true; } } </code></pre>
