在我的应用程序中,我正在使用CardView UI元素。我有两个CardView元素,我想在UI中显示。这是我的代码。
<?xml version="1.0" encoding="utf-8"?>
<android.support.v7.widget.CardView
xmlns:card_view="http://schemas.android.com/apk/res-auto"
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/card_view"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
card_view:cardUseCompatPadding="true"
card_view:cardCornerRadius="8dp"
android:layout_marginBottom="16dp">
<LinearLayout android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent">
<TextView
android:id="@+id/display_name"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:textSize="13sp"
android:text="@string/app_name"
android:textColor="#ffffff"
android:paddingBottom="8dp"
android:paddingTop="8dp"
android:gravity="center_horizontal"
android:layout_alignParentBottom="true"
android:background="#1976D2"/>
<ImageView
android:id="@+id/display_image"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:contentDescription="@string/action_settings"
android:scaleType="centerCrop" />
<TextView
android:id="@+id/display_information"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:textSize="13sp"
android:text="@string/app_name"
android:textColor="#ffffff"
android:layout_below="@+id/display_image"
android:paddingBottom="8dp"
android:paddingTop="8dp"
android:gravity="center_horizontal"
android:layout_alignParentBottom="true"
android:background="#1976D2"/>
</LinearLayout>
</android.support.v7.widget.CardView>
这是ViewHolder&amp;我正在使用的Adpater课程。
public class DisplayItemRecyclerViewAdapter extends RecyclerView.Adapter<DisplayItemViewHolders> {
private List<DisplayItemInformation> itemList;
private Context context;
public DisplayItemRecyclerViewAdapter(Context context, List<DisplayItemInformation> itemList) {
this.itemList = itemList;
this.context = context;
}
@Override
public DisplayItemViewHolders onCreateViewHolder(ViewGroup parent, int viewType) {
View layoutView = LayoutInflater.from(parent.getContext()).inflate(R.layout.display_card, parent, false);
layoutView.setLayoutParams(new RecyclerView.LayoutParams(RecyclerView.LayoutParams.MATCH_PARENT, RecyclerView.LayoutParams.WRAP_CONTENT));
DisplayItemViewHolders rcv = new DisplayItemViewHolders(layoutView);
return rcv;
}
@Override
public void onBindViewHolder(DisplayItemViewHolders holder, int position) {
holder.name.setText(itemList.get(position).getName());
holder.image.setImageResource(itemList.get(position).getPhoto());
}
@Override
public int getItemCount() {
return this.itemList.size();
}
}
public class DisplayItemViewHolders extends RecyclerView.ViewHolder implements View.OnClickListener {
public TextView name;
public TextView detailedInformation;
public ImageView image;
//private final Context context;
public DisplayItemViewHolders(View itemView) {
super(itemView);
itemView.setOnClickListener(this);
//context = itemView.getActivity();
name = (TextView) itemView.findViewById(R.id.display_name);
image = (ImageView) itemView.findViewById(R.id.display_image);
}
@Override
public void onClick(View view) {
Intent intent = new Intent(view.getContext(), importantDatesDashboardActivity.class);
view.getContext().startActivity(intent);
Toast.makeText(view.getContext(), "New ACTIVITY started 111 = " + getAdapterPosition(), Toast.LENGTH_SHORT).show();
}
}
在上面的代码中,我想调整两张卡的宽度和高度以适应屏幕?我如何调整宽度和宽度卡的高度和垂直显示卡?这里要注意的是卡内显示的图像大于屏幕尺寸。
