Question

当我尝试使用GridView和DrawerLayout打开Activity时，出现错误：

这是活动的代码：

的活动：

public class usuarios extends ActionBarActivity {

private ArrayList<String> datos;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_usuarios);


    //Caso de prueba, luego sera la consulta a la base de datos
    datos = new ArrayList<String>();
    datos.add("Dario");
    datos.add("Marcelito");
    datos.add("Sagal");
    datos.add("Miguel");
    datos.add("Antonio");
    datos.add("Agustin");

    GridView grid = (GridView) findViewById(R.id.gridView);

    //se pasan los datos recogidos de la base de datos
    grid.setAdapter(new MyAdapter(this, datos));

}

MyAdapter：

public class MyAdapter extends BaseAdapter {
private List items = new ArrayList();
private LayoutInflater inflater;

public MyAdapter(Context context, ArrayList<String> datos)
{
    inflater = LayoutInflater.from(context);

    //se cargan todos los nombres "datos"
    for(int i = 0 ; i<datos.size(); i++)
    {
        items.add(new Item(datos.get(i), R.drawable.colores));
    }
}

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

@Override public Object getItem(int i)
{
    return items.get(i);
}

@Override public long getItemId(int i)
{
    //return items.get(i).drawableId;
    return 4;
}

@Override public View getView(int i, View view, ViewGroup viewGroup)
{
    View v = view;
    ImageView picture;
    TextView name;

    if(v == null)
    {
        v = inflater.inflate(R.layout.activity_usuarios, viewGroup, false);
        v.setTag(R.id.picture, v.findViewById(R.id.picture));
        v.setTag(R.id.text, v.findViewById(R.id.text));
    }

    picture = (ImageView)v.getTag(R.id.picture);
    name = (TextView)v.getTag(R.id.text);
    Item item = (Item)getItem(i);
    picture.setImageResource(item.drawableId);
    name.setText(item.name);
    return v;
}

 private class Item
{
    final String name;
    final int drawableId;

    Item(String name, int drawableId)
    {
        this.name = name;
        this.drawableId = drawableId;
    }
}
}

Answer 1

您为R.layout.activity_usuarios中的每一行夸大了MyAdapter，而不是特定于GridView的布局。

这导致每行内部都有DrawerLayout，GridView和ListView，这可能不是您想要的。

DrawerLayout出错
