我有这个 items.xml 文件
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="horizontal" android:layout_width="match_parent"
android:focusable="true"
android:clickable="true"
android:background="?android:attr/selectableItemBackground"
android:layout_height="wrap_content">
<ImageView
android:layout_width="match_parent"
android:layout_height="60dp"
android:id="@+id/colorPreview" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:textAppearance="@android:style/TextAppearance.Large"
android:textColor="@android:color/white"
android:id="@+id/colorName" />
</RelativeLayout>
当我单独使用它时,可选择的项背景会在我点击视图时执行动画。但是当我将其用于RecyclerView中的项时,单击效果不再发生。我该如何解决这个问题?
PS:如果相关的话,这是RecyclerView上的监听器:
public ColorListOnItemTouchListener(Context context, OnItemClickListener clickListener) {
mClickListener = clickListener;
mGestureDetector = new GestureDetector(context, new GestureDetector.SimpleOnGestureListener() {
@Override
public boolean onDown(MotionEvent e) {
return true;
}
@Override
public void onLongPress(MotionEvent e) {
if(childView != null && mClickListener != null) {
mClickListener.onItemLongPress(childView, index);
}
}
@Override
public boolean onSingleTapUp(MotionEvent e) {
if(childView != null && mClickListener != null) {
mClickListener.onItemClick(childView, index);
}
return true;
}
@Override
public boolean onFling(MotionEvent e1, MotionEvent e2, float velocityX, float velocityY) {
return false;
}
});
}
谢谢!
编辑:
public class ColorsCursorAdapter extends RecyclerView.Adapter<ColorsCursorAdapter.ViewHolder> {
private static final int layout = R.layout.color_item;
private Cursor mCursor;
public ColorsCursorAdapter(Cursor c) {
super();
this.mCursor = c;
}
@Override
public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View v = LayoutInflater.from(parent.getContext()).inflate(layout, parent, false);
TextView name = (TextView) v.findViewById(R.id.colorName);
ImageView image = (ImageView) v.findViewById(R.id.colorPreview);
return new ViewHolder(v, name, image);
}
@Override
public void onBindViewHolder(ViewHolder holder, int position) {
mCursor.moveToPosition(position);
int color = mCursor.getInt(mCursor.getColumnIndex(ColorItem.COLUMN_COLOR));
holder.colorName.setText(Utils.getColorString(color));
holder.colorPreview.setImageDrawable(new ColorDrawable(color));
}
@Override
public int getItemCount() {
if(mCursor != null) {
return mCursor.getCount();
}
return 0;
}
public void swapCursor(Cursor c) {
mCursor = c;
notifyDataSetChanged();
}
public Cursor getCursor() {
return mCursor;
}
public static class ViewHolder extends RecyclerView.ViewHolder {
public TextView colorName;
public ImageView colorPreview;
public ViewHolder(View root, TextView colorName, ImageView colorPreview) {
super(root);
root.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
//
}
});
this.colorName = colorName;
this.colorPreview = colorPreview;
}
}
}
适配器是使用以下方式创建的:
colorList.setLayoutManager(new LinearLayoutManager(this));
adapter = new ColorsCursorAdapter(null);
colorList.setAdapter(adapter);
