如何在网格中设置“替换单元格颜色”

Question

如何在网格中设置备用单元格颜色？我发现了很多问题/教程关于如何设置行颜色但不设置关于细胞的颜色。提前感谢

Answer 1

如果你有很多listView的例子，为什么不使用getView方法呢？因为getView方法用于adapter，adapter同时用于视图、列表和网格。只需根据视图在adapteview中的位置设置视图的背景即可。

protected void getView(AdapterView<> adapterView, View convertView, int position, long id)
{
    LayoutInflater inflater = (LayoutInflater)context.getSystemService
      (Context.LAYOUT_INFLATER_SERVICE);
    View view =inflater.inflate(yourlayout.xml, null);
    if(position%2==0)
        view.setBackgroundColor(color1);
    else
        view.setBackgroundColor(color2);
     return view;
}

向前迈进一步，它可以实现

public class ListViewA extends Activity {
GridView MyGrid;
@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
    MyGrid = (GridView) findViewById(R.id.gridview);
    MyGrid.setAdapter(new ImageAdapter(this));
}
public class ImageAdapter extends BaseAdapter {
    Context MyContext;
    public ImageAdapter(Context _MyContext) {
        MyContext = _MyContext;
    }
    @Override
    public int getCount() {
        return 9;
    }
    public View getView(int position, View convertView, ViewGroup parent) {
        View view = convertView;
        if (convertView == null) {
            LayoutInflater li = getLayoutInflater();
            view = li.inflate(R.layout.main, null);
        }
        if (position % 2 == 0)
            view.setBackgroundColor(0x30FF0000);
        else
            view.setBackgroundColor(0x300000FF);
        return view;
    }
    @Override
    public Object getItem(int arg0) {
        // TODO Auto-generated method stub
        return null;
    }
    @Override
    public long getItemId(int arg0) {
        // TODO Auto-generated method stub
        return 0;
    }
}

}
