如何设置setImageResource，我有手机的图库图片的URI

Question

我将来自图库的手机图像的所有URI设置为：

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

其输出是：

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

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

imageView.setImageResource(mThumbIds[position]);

哪里：

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

我的gridview是：

<GridView xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/gridview"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:columnWidth="90dp"
    android:numColumns="auto_fit"
    android:verticalSpacing="10dp"
    android:horizontalSpacing="10dp"
    android:stretchMode="columnWidth"
    android:gravity="center"
    />

我想知道如何动态设置图像，因为直到运行时我都不知道画廊中有多少图像及其URI。

您将需要使用一个可以为您填充网格的适配器。 等待直到获得有关图像的信息，然后适当地填充适配器。 在此处可以找到一个很好的教程，展示了如何使用gridviews以及如何使用图像和文本填充它们。
