android - Manipulating a ListView's items contained in a ViewHolder - Unexpected behaviour -

I am facing some strange behavior in your code that you will find below. I have a button in each of my ListView and if it is clicked, I want to gray the line and hide the button. To make the change permanent, I have set up a property in the custom ViewHolder , so the changes are continuous.

However, if clicking on the button, changes to item 1 will apply. For items 6. It does not affect any other line on other items or it affects more than one line. I suspect that I have something to declare some final variables, but I can not believe it. I tried to apply different solutions (reducing the number of final variables, using different variables, ect), but nothing really does not seem to work.

I need some help. Thanks!

 I believe that you reset the alpha to the initial position If the  processed ()  is false.  
 something like:  
  private void set Krenpradrshnmod (See Knhwartwu, fruit lock Dekenholder Dekenholder) {if (viewHolder.wasConsumed ()) {ConvertView.setAlpha (0.5 F ); ConvertView.setBackgroundColor (Color.GRAY); } Else {convertView.setAlpha (1f); // ConvertViews Setbackgram colore (color. WHITE) worth more than //; // or whatever color}}   
 Your problem is that you are reusing the same scene, but you will have the same alpha. Placeholder  and do not determine the state based on  convertView # alpha    .
