Question

我有一个GridView of Images，下面是与该图像相关的文本，我将它放在一个字符串数组中。现在，当我尝试在gridview中的图像下面打印数组的内容时，它会在所有图像中显示该字符串数组的字符串的完整列表。例如我的字符串数组如下：

public static String[] gname = 
{"ImageA", "ImageB","ImageC", "ImageD","ImageE"
    };

我的输出在gridView图像下方为

"ImageA,ImageB,ImageC,ImageD,ImageE"

在网格中的每个图像中。

我希望ImageA在一个图像下显示，ImageB在另一个图像中显示。这怎么可能。哪里错了。请通过查看以下代码告诉我：

MainActivity.java

package com.example.imageandtext;

import java.util.ArrayList;
import java.util.Arrays;
import android.app.Activity;
import android.content.res.TypedArray;
import android.graphics.Bitmap;
import android.graphics.BitmapFactory;
import android.os.Bundle;
import android.widget.GridView;

public class MainActivity extends Activity {
private GridView gridView;
private GridViewAdapter customGridAdapter;

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

    gridView = (GridView) findViewById(R.id.gridView);
    customGridAdapter = new GridViewAdapter(this, R.layout.row_grid, getData());
    gridView.setAdapter(customGridAdapter);
}
public static String[] gname = {
    "ImageA", "ImageB",
    "ImageC", "ImageD",
    "ImageE"

};


private ArrayList getData() {
    final ArrayList imageItems = new ArrayList();
    // retrieve String drawable array
    TypedArray imgs = getResources().obtainTypedArray(R.array.image_ids);
    for (int i = 0; i < imgs.length(); i++) {
        Bitmap bitmap = BitmapFactory.decodeResource(this.getResources(),
                imgs.getResourceId(i, -1));

    // Arrays.toString(gname) is somewhat wrong here.. how to correct it?

        imageItems.add(new ImageItem(bitmap, Arrays.toString(gname)));
    }

    return imageItems;

}

}

Answer 1

尝试：

imageItems.add（new ImageItem（bitmap，gname [i]））;

String Array显示GridView中的完整列表
