我不明白爲什麼onclick不適用於圖像。我試圖添加clickable和focusable，但沒有運氣。圖像視圖不可點擊在視圖中
我的XML具有圖像視圖：

我viewHolder：
public static class MessageViewHolder extends RecyclerView.ViewHolder {
public EmojiconTextView messageTextView;
public TextView messengerTextView;
public CircleImageView messengerImageView;
public ImageView sendimage;
public ImageView videoview;
public TextView messageTime;
public ImageView acceptmedia;
public ImageView notacceptmedia;
public MessageViewHolder(View v) {
super(v);
messageTextView = (EmojiconTextView) itemView.findViewById(R.id.messageTextView);
messengerTextView = (TextView) itemView.findViewById(R.id.messengerTextView);
messengerImageView = (CircleImageView) itemView.findViewById(R.id.messengerImageView);
sendimage = (ImageView) itemView.findViewById(R.id.image);
videoview = (ImageView) itemView.findViewById(R.id.videoview);
messageTime = (TextView)itemView.findViewById(R.id.message_time);
acceptmedia =(ImageView) itemView.findViewById(R.id.acceptmedia);
notacceptmedia = (ImageView) itemView.findViewById(R.id.notacceptmedia);
}
}
守則的onclick落實的ImageView：
viewHolder.acceptmedia.setClickable(true);
//viewHolder.acceptmedia.setFocusable(true);
viewHolder.acceptmedia.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Toast.makeText(GroupChatScreen.this, "Accept", Toast.LENGTH_SHORT).show();
Log.e("test","Accept");
}
});
viewHolder.notacceptmedia.setClickable(true);
//viewHolder.notacceptmedia.setFocusable(true);
viewHolder.notacceptmedia.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Toast.makeText(GroupChatScreen.this, "Decline", Toast.LENGTH_SHORT).show();
Log.e("test","Decline");
}
});
我想知道你在'ViewHolder'中使用'itemView'的原因，以及你爲什麼不使用'v'。你能發佈更多適配器和'ViewHolder'代碼嗎？特別是處理'itemView'的東西？ – Cheticamp
