Question

我有一个自定义布局，我包含在另一个布局中。现在我想从设置较大布局的活动设置第一个布局的视图作为其contentView。我想过创建一个baseAdapter，但我被卡住了。这是我尝试过的：

主要布局：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:focusable="true"
    android:focusableInTouchMode="true"
    android:orientation="vertical"
    android:weightSum="3">
//...
                <android.support.v7.widget.CardView xmlns:card_view="http://schemas.android.com/apk/res-auto"
                    android:id="@+id/offer_card_view"
                    android:layout_width="fill_parent"
                    android:layout_height="wrap_content"
                    android:layout_gravity="center"
                    android:layout_marginLeft="@dimen/container_margin"
                    android:layout_marginStart="@dimen/container_margin"
                    android:layout_marginRight="@dimen/container_margin"
                    android:layout_marginEnd="@dimen/container_margin"
                    android:gravity="center"
                    android:padding="20dp"
                    card_view:cardCornerRadius="4dp">

                    <include layout="@layout/offer" />

                </android.support.v7.widget.CardView>

活动：

    Public class MainActivity {
         @Override
         public void onCreate(Bundle savedInstanceState) {
         super.onCreate(savedInstanceState);
         this.setContentView(R.layout.expanded_shop_profile_activity);
         //...
         offer_adapter mOfferAdapter = new offer_adapter(getApplicationContext());
         CardView offer_card_view = (CardView) findViewById(R.id.offer_card_view);
         offer_card_view.setAdapter(mOfferAdapter);
}

我试过的适配器： public class offer_adapter扩展了BaseAdapter {

private Context _context;
private LayoutInflater infalInflater;

public  offer_adapter(Context context) {
    _context = context;
    infalInflater = (LayoutInflater) this._context
            .getSystemService(Context.LAYOUT_INFLATER_SERVICE);

}



@Override
public int getCount() {
    return 0;
}

@Override
public Object getItem(int position) {
    return null;
}

@Override
public long getItemId(int position) {
    return 0;
}

@Override
public View getView(int position, View myView, ViewGroup parent) {
    View  convertView = myView;

    if (myView == null) {
        // if it's not recycled, initialize some attributes
        convertView = infalInflater.inflate(R.layout.offer, null);
    } else {
        convertView = (View) myView;
    }

    initializeUniversalImageLoader();
    //getting the layout views
    offer_thumb = (ImageButton) convertView.findViewById(R.id.offer_thumb);
    offer_type = (ImageButton) convertView.findViewById(R.id.offer_type);
    final TextView offer_name = (EditText) convertView.findViewById(R.id.offer_name);
    final TextView offer_start_date = (TextView) convertView.findViewById(R.id.offer_start_date);
    final TextView offer_end_date = (TextView) convertView.findViewById(R.id.offer_end_date);
    final TextView offer_details = (EditText) convertView.findViewById(R.id.offer_details);
    wheel=(ProgressWheel) convertView.findViewById(R.id.progress_wheel);
    wheel.setBarColor(Color.BLUE);
    wheel.setVisibility(View.INVISIBLE);
    offer_name.setText("someText");
    offer_start_date.setText("someText");
    offer_end_date.setText("someText");
    offer_details.setText("someText");
 //....
    return convertView;
}

}

这种方法对吗？我错过了什么？

Answer 1

CardView不是AdapterView所以我不知道如何在其上调用setAdapter()。但是，它是ViewGroup，因此您每次要添加视图时都可以调用addView()。

Answer 2

正如kris larson所说：CardView不是AdapterView。他是对的。而不是你可以使用的是RecyclerView，如果你想填充Cardview，你可以在SubLayout中的scrollView（根据你的要求）之前添加它，在主布局中你可以添加RecylerView（适用于你的ListView）并删除cardview。

如何以编程方式填充包含在另一个布局中的自定义布局？
