Question

我将来自Gallery的手机图像的所有URI都包含在：

false

其输出是：

for(String item: items) {
    Log.d("Images", item);
}

我想在gridview中填充这些内容。我们可以将Drawable中的静态图像设置为：

07-04 17:30:22.633  11140-11140/com.example.android.HomeWork2 D/Images﹕ /storage/emulated/0/DCIM/Camera/IMG_20150425_131643.jpg

其中：

imageView.setImageResource(mThumbIds[position]);

我的gridview是：

private Integer[] mThumbIds = {
     R.drawable.ic_launcher,R.drawable.ic_launcher
};

我想知道如何动态设置图像，因为我不知道图库中有多少图像及其URI直到运行时。

您需要使用适合为您填充网格的适配器。等到你有关于图像的信息，然后适当地填充适配器。可以找到一个很好的教程，展示如何使用网格视图并用图像+文本填充它们here。

如何设置setImageResource，我有手机图库图像的URI
