Question

我正在为Android电视开发应用程序。 dpad方向导航键有效，但不能输入键（中间键）。我对dpad编码不了解。请帮忙。

custom adapter.java

public class CustomAdapter extends BaseAdapter {

Context c;
ArrayList<Spacecraft> spacecrafts;

public CustomAdapter(Context c, ArrayList<Spacecraft> spacecrafts) {
    this.c = c;
    this.spacecrafts = spacecrafts;
}

@Override
public int getCount() {
    return spacecrafts.size();
}

@Override
public Object getItem(int position) {
    return spacecrafts.get(position);
}

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

@Override
public View getView(int position, View convertView, ViewGroup parent) {
    if(convertView==null)
    {
        convertView= LayoutInflater.from(c).inflate(R.layout.model,parent,false);
    }

    TextView nameTxt= (TextView) convertView.findViewById(R.id.nameTxt);
    ImageView img= (ImageView) convertView.findViewById(R.id.spacecraftImage);

    final Spacecraft s= (Spacecraft) this.getItem(position);

    nameTxt.setText(s.getName());
    PicassoClient.downloadImage(c, s.getImageUrl(), img);


    convertView.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            Toast toast = Toast.makeText(c.getApplicationContext(), "This is a message displayed", Toast.LENGTH_SHORT); toast.show();
            openDetailACtivity(s.getName(),s.getPropellant(),s.getDescription(),s.getImageUrl());
        }
    });

    return convertView;
}



private void openDetailACtivity(String name,String propellant,String description,String imageUrl)
{
    Intent i=new Intent(c, channel.class);

    //PACK DATA
    i.putExtra("NAME_KEY",name);
    i.putExtra("PROPELLANT_KEY",propellant);
    i.putExtra("DESCRIPTION_KEY",description);
    i.putExtra("IMAGEURL_KEY",imageUrl);

    c.startActivity(i);
}

}

我试图单击网格视图中的ImageView。我可以在模拟器上用鼠标单击图像，但不能用Dpad单击图像。而我的xml代码是

model.xml

<?xml version="1.0" encoding="utf-8"?>
<android.support.v7.widget.CardView 
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="horizontal" android:layout_width="match_parent"
xmlns:card_view="http://schemas.android.com/apk/res-auto"
android:layout_margin="10dp"
card_view:cardCornerRadius="5dp"
card_view:cardElevation="5dp"
android:layout_height="100dp">

<LinearLayout
    android:orientation="horizontal"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <ImageView
        android:layout_width="fill_parent"
        android:imeOptions="actionGo"
        android:layout_height="fill_parent"
        android:id="@+id/spacecraftImage"
        android:background="@drawable/background"
        android:src="@drawable/play" />

    <TextView
        android:id="@+id/nameTxt"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_alignParentLeft="true"
        android:padding="1dp"
        android:text="Name"
        android:textAppearance="?android:attr/textAppearanceLarge"
        android:textColor="@color/colorAccent" />

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