public PostAdapterViewHolder (final View itemView) {
    super(itemView);
    itemView.setOnClickListener(this);
    head = (RelativeLayout) itemView.findViewById(R.id.head);
    content = (LinearLayout) itemView.findViewById(R.id.content);
    imageView =(ImageView)itemView.findViewById(R.id.imageview);
    designation = (TextView) itemView.findViewById(R.id.designation);
    like =(ImageView)itemView.findViewById(R.id.like);

            ImageView i = (ImageView) itemView.findViewById(R.id.like);
            Drawable a = i.getBackground();

            if (a.getConstantState().equals(context.getDrawable(R.drawable.emptyup).getConstantState())){

                i.setImageDrawable(context.getDrawable(R.drawable.fillup));

            } else {

                i.setImageDrawable(context.getDrawable(R.drawable.emptyup));

            }

        }

Answer 1

Your app crash when the activity concerned should be displayed ?

Check if in you activity you have a drawable v24 like this

Then, if yes, change the display of your files from Android to Project at the very top of the hierarchy of your files : From

to

And drag and drop the drawable in the directory drawable v-24 to the directory drawable.

That's all. Try if it's ok

Edit : I found that the problem may arise on the Android 6 API 23 but not for higher API

Answer 2

By seeing the logs. The problem is in your drawable background take a look at it. You have type X24 image change it and it will fix your problem.

Second thing is you are seeing two images at a time. So you need to remove the background that you are setting in your .xml file and you are good to go.

Answer 3

<CheckBox android:layout_width="wrap_content"
 android:layout_height="wrap_content" 
 android:text="new checkbox"
 android:background="@drawable/checkbox_background" 
 android:button="@drawable/checkbox" />

Try to use checkbox instead of ImageView

<?xml version="1.0" encoding="utf-8"?>

<selector xmlns:android="http://schemas.android.com/apk/res/android">
 <item android:state_checked="true" android:state_focused="true"
  android:drawable="@drawable/fillup" />
 <item android:state_checked="false" android:state_focused="true"
  android:drawable="@drawable/emptyup" />
 <item android:state_checked="false"
  android:drawable="@drawable/emptyup" />
 <item android:state_checked="true"
  android:drawable="@drawable/fillup" />
</selector>

if (a.getConstantState().equals(context.getDrawable(R.drawable.emptyup).getConstantState())){

            i.setImageDrawable(context.getDrawable(R.drawable.fillup));

        } else {

            i.setImageDrawable(context.getDrawable(R.drawable.emptyup));

        }

These lines are giving you error because of your android version issue.

Answer 4

Follow this https://developer.android.com/guide/topics/graphics/vector-drawable-resources.html#vector-drawables-backward-solution, You should use setImageResource() instead of setImageDrawable()

Answer 5

Please try a clean build, may be the R file is wrong

Answer 6

Check if the drawable resource image is in drawable folder, not drawable-24.
I already have this problem but solve it by moving the image resource to drawable folder.
