Question

请帮我解决这个问题。我已经尝试了很多东西，甚至是How to show Text on Image的响应，但没有获得所需的输出，如该页面的第一张图片所示。我正在尝试使用文本叠加显示图像。我有一个代码用Lazy Adapter加载图像。但是显示的图像在两侧都有填充。这是我得到的

以下是我的代码：

tile layout xml

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content">

        <ImageView
            android:id="@+id/tileimage"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:contentDescription="@string/logo"
             />

        <LinearLayout
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:layout_alignParentBottom="true"
            android:orientation="vertical" >


            <TextView
                android:id="@+id/tilecontent"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:gravity="center"
                android:textColor="#FFF"
                android:textSize="16sp"
                android:textStyle="bold"
                android:background="#55000000" />
        </LinearLayout>
</RelativeLayout>

网格布局

<FrameLayout 
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
>
<GridView
    android:id="@+id/gridview"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:verticalSpacing="1dp"
    android:horizontalSpacing="1dp"
    android:stretchMode="columnWidth"
    android:numColumns="2" 
    />
</FrameLayout>

我从这里给瓦片充气

public class LazyAdapter extends BaseAdapter {

private Activity activity;
private String[] content;
private static LayoutInflater inflater=null;
public ImageLoader imageLoader; 

public LazyAdapter(Activity act, String[] cont) {
    activity = act;
    content = cont;
    inflater = (LayoutInflater)activity.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    imageLoader = new ImageLoader(activity.getApplicationContext());
}

public int getCount() {
    return content.length;
}

public Object getItem(int position) {
    return position;
}

public long getItemId(int position) {
    return position;
}

public View getView(final int position, View convertView, ViewGroup parent) {
    View view = convertView;

    if(convertView == null) 
        view = inflater.inflate(R.layout.hometile, parent, false);
    view.setId(position);
    TextView text=(TextView)vi.findViewById(R.id.tilecontent);;
    ImageView image=(ImageView)vi.findViewById(R.id.tileimage);

    if(position == 0)
    {
        text.setText("One");
    }
    else if(position == 1)
    {
        text.setText("Two");
    }
    else if(position == 2)
    {
        text.setText("Three");
    }
    else if(position == 3)
    {
        text.setText("Four");
    }
    else if(position == 4)
    {
        text.setText("Five");
    }
    else if(position == 5)
    {
        text.setText("Six");
    }


    imageLoader.DisplayImage(data[position], image);

    return view;
}

图像是否小于网格图块？如果您需要扩展它们，请使用one of these options
