我想在我的应用中创建静态网格视图。它应该是5X5维度。我知道如何构建它,但我不明白的是,我想将一个蓝色图像膨胀到网格的所有行和列。我无法弄清楚如何实现这一目标。我认为如果我们使用适配器,我们应该有一个图像列表,但我只有一个图像。

如果你只想用5 X 5渲染相同的图像。
创建activity_main.xml
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
tools:context=".MainActivity" >
<GridView
android:id="@+id/gridView1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_below="@+id/textView1"
android:numColumns="5" >
</GridView>
<TextView
android:id="@+id/textView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textSize="25dp"
android:textStyle="bold"
android:text=" Computer Languages..." />
</RelativeLayout>

创建CustomAdapter。 及其布局 gv=(GridView) findViewById(R.id.gridView1);
gv.setAdapter(new CustomAdapter(this));
public class CustomAdapter extends BaseAdapter {
int count = 10;
Context context;
private static LayoutInflater inflater=null;
public CustomAdapter(MainActivity mainActivity) {
// TODO Auto-generated constructor stub
context=mainActivity;
inflater = ( LayoutInflater )context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
}
@Override
public int getCount() {
// TODO Auto-generated method stub
return count;
}
@Override
public Object getItem(int position) {
// TODO Auto-generated method stub
return position;
}
@Override
public long getItemId(int position) {
// TODO Auto-generated method stub
return position;
}
@Override
public View getView(final int position, View convertView, ViewGroup parent) {
// TODO Auto-generated method stub
View rowView = inflater.inflate(R.layout.image_list, null);
return rowView;
}
}
