I am Trying to implement like feature in the app, here is the snippet from the Viewholder in the recycled view.
Recycler customadapter
public class PostAdapterViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener {
TextView title,user,description,tag,time,designation;
Long date;
ImageView imageView,bookmark,profilepic,sharebutton,like;
RelativeLayout head;
LinearLayout content;
DatabaseReference reference;
Context context;
String name;
public void setContext(Context context) {
this.context = context;
}
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);
profilepic = (ImageView) itemView.findViewById(R.id.imageView2);
bookmark =(ImageView)itemView.findViewById(R.id.bookmark);
title = (TextView) itemView.findViewById(R.id.title);
description = (TextView) itemView.findViewById(R.id.description);
time = (TextView) itemView.findViewById(R.id.date);
tag = (TextView) itemView.findViewById(R.id.tag);
sharebutton = (ImageView) itemView.findViewById(R.id.sharebutton);
user = (TextView) itemView.findViewById(R.id.username);
like.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
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));
}
}
});
}
}
}

回答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
回答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.
回答3:
You are using context.getDrawable(R.drawable.fillup) which will only work in versions higher than LOLLIPOP. Use context.getResources().getDrawable(R.drawable.fillup) to get the images from resource.
回答4:
<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.
回答5:
Follow this https://developer.android.com/guide/topics/graphics/vector-drawable-resources.html#vector-drawables-backward-solution, You should use setImageResource() instead of setImageDrawable()
回答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.
回答7:
Please try a clean build, may be the R file is wrong
