Question

我在安装GridView时遇到了Android间距问题。基本上，我正在组装一个9x9游戏板。我有一个GridView正常工作，但是在水平方向上每个定义正方形后都有不必要的间距（垂直正常） - 因此它不能正确适合工作区域。

编辑：看起来GridView已经为每平方宽度分配了50dp，当我只想要它是30dp时...不确定为什么或如何更改它？

自定义网格代码：

import android.content.Context;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.BaseAdapter;
import android.widget.ImageView;

public class CustomGrid extends BaseAdapter {
    private Context mContext;
    private final int[] Imageid;


    public CustomGrid(Context c, int[] Imageid) {
        mContext = c;
        this.Imageid = Imageid;
    }

    @Override
    public int getCount() {
        return Imageid.length;
    }

    @Override
    public Object getItem(int position) {
        return null;
    }

    @Override
    public long getItemId(int position) {
        return 0;
    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        View grid;
        LayoutInflater inflater = (LayoutInflater) mContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE);

        if (convertView == null) {
            grid = new View(mContext);
            grid = inflater.inflate(R.layout.gridsingle, null);
            ImageView imageView = (ImageView) grid.findViewById(R.id.grid_image);
            imageView.setPadding(0,0,0,0);
            imageView.setAdjustViewBounds(true);
            imageView.setImageResource(Imageid[position]);
        } else {
            grid = (View) convertView;
        }

        return grid;
    }
}

主要观点摘录：

public class Gameplay extends Activity {
GridView grid;

    int[] imageId = {
            R.drawable.square, R.drawable.square, R.drawable.square, R.drawable.square, R.drawable.square, R.drawable.square, R.drawable.square, R.drawable.square, R.drawable.square,
            R.drawable.square, R.drawable.square, R.drawable.square, R.drawable.square, R.drawable.square, R.drawable.square, R.drawable.square, R.drawable.square, R.drawable.square,
            R.drawable.square, R.drawable.square, R.drawable.square, R.drawable.square, R.drawable.square, R.drawable.square, R.drawable.square, R.drawable.square, R.drawable.square,
            R.drawable.square, R.drawable.square, R.drawable.square, R.drawable.square, R.drawable.square, R.drawable.square, R.drawable.square, R.drawable.square, R.drawable.square,
            R.drawable.square, R.drawable.square, R.drawable.square, R.drawable.square, R.drawable.square, R.drawable.square, R.drawable.square, R.drawable.square, R.drawable.square,
            R.drawable.square, R.drawable.square, R.drawable.square, R.drawable.square, R.drawable.square, R.drawable.square, R.drawable.square, R.drawable.square, R.drawable.square,
            R.drawable.square, R.drawable.square, R.drawable.square, R.drawable.square, R.drawable.square, R.drawable.square, R.drawable.square, R.drawable.square, R.drawable.square,
            R.drawable.square, R.drawable.square, R.drawable.square, R.drawable.square, R.drawable.square, R.drawable.square, R.drawable.square, R.drawable.square, R.drawable.square,
            R.drawable.square, R.drawable.square, R.drawable.square, R.drawable.square, R.drawable.square, R.drawable.square, R.drawable.square, R.drawable.square,R.drawable.square

    };
@Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_gameplay);
 CustomGrid adapter = new CustomGrid(Gameplay.this, imageId);
        grid=(GridView)findViewById(R.id.grid);
            grid.setAdapter(adapter);
            grid.setOnItemClickListener(new AdapterView.OnItemClickListener() {
                @Override
                public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
                Toast.makeText(Gameplay.this, "You Clicked x", Toast.LENGTH_SHORT).show();

            }
        });

gridview xml：

   <LinearLayout 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"
        tools:context=".MainActivity" >

        <GridView
            android:numColumns="9"
            android:gravity="center"
            android:columnWidth="30dp"
            android:stretchMode="none"
            android:layout_width="fill_parent"
            android:layout_height="fill_parent"
            android:horizontalSpacing="0dp"
            android:id="@+id/grid"
            />

    </LinearLayout>

imageview xml：

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="30dp"
    android:layout_height="30dp"
    android:padding="0dp" >


<ImageView
        android:id="@+id/grid_image"
        android:layout_width="30dp"
        android:layout_height="30dp"
        android:stretchMode="none">
    </ImageView>

</LinearLayout>

最终结果如下： test screen

我尝试过调整宽度和使用StretchMode参数等明显的想法，但还没有运气。有什么想法吗？

非常感谢。

我解决了我的问题 - 事实证明我的gridview（id网格）有相互冲突的布局 - 一旦我删除了废弃的布局，一切都开始工作了！
