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没有关于细胞的颜色。提前致谢

Answer 1

如果你有很多listView的例子，为什么不使用getView方法，因为getView方法用于适配器，而适配器用于视图，列表和网格。只需根据适配器视图中的视图位置设置视图背景。

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;
}

向前迈出一步，它有效

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;
    }
}

}
