Java 如何设置setImageResource，我有手机图库图像的URI

我将Gallery中手机图像的所有URI设置为：

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

其产出是：

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

imageView.setImageResource(mThumbIds[position]);

其中：

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

我的观点是：

<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，因为直到运行时我才知道库中有多少图像及其URI。

您需要使用一个适配器来填充网格。等待获得有关映像的信息，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GridView并用图像+文本填充它们
