我已經嘗試了很多，但無法使這個工作。我有一些網格圖片，我想用d-pad來瀏覽它。爲此我實現了setOnKeyListerner，但它給了我這個錯誤。 「無法解析setOnKeyListener（匿名方法android.view.View.OnKeyListener）」SetOnKeyListener不能與gridview一起工作
public class GridView_Holder extends RecyclerView.ViewHolder implements
OnClickListener {
// View holder for gridview recycler view as we used in listview
public TextView grid_title, grid_location, grid_date;
public ImageView grid_imageView, grid_delete;
public RelativeLayout gridLayout;
private RecyclerView_OnClickListener.OnClickListener onClickListener;
public GridView_Holder(View view) {
super(view);
// Find all views ids
this.grid_title = (TextView) view.findViewById(R.id.grid_title);
this.grid_location = (TextView) view.findViewById(R.id.grid_location);
this.grid_date = (TextView) view.findViewById(R.id.grid_dateconstructed);
this.grid_imageView = (ImageView) view.findViewById(R.id.grid_imageview);
this.grid_delete = (ImageView) view.findViewById(R.id.grid_delete);
this.gridLayout = (RelativeLayout) view.findViewById(R.id.grid_layout);
// Implement click listener over views that we want
this.gridLayout.setOnClickListener(this);
this.grid_delete.setOnClickListener(this);
}
@Override
public void onClick(View v) {
// set custom listener
if (onClickListener != null) {
onClickListener.OnItemClick(v, getAdapterPosition());
}
}
// Setter for listener
public void setClickListener(
RecyclerView_OnClickListener.OnClickListener onClickListener) {
this.onClickListener = onClickListener;
}
