how to display images saved in sdcard folder in android [closed]
Solution 1:
You can get the path of files from a particualr folder as below
Once you get the path of files you ca display the images in gridview
ArrayList<String> f = new ArrayList<String>();// list of file paths
File[] listFile;
public void getFromSdcard()
{
File file= new File(android.os.Environment.getExternalStorageDirectory(),"TMyFolder");
if (file.isDirectory())
{
listFile = file.listFiles();
for (int i = 0; i < listFile.length; i++)
{
f.add(listFile[i].getAbsolutePath());
}
}
}
Remember to add permissionin manifest file
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
By having write permission will have read permission by default.
Example
main.xml
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent" android:layout_height="fill_parent">
<GridView
android:id="@+id/PhoneImageGrid"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:columnWidth="90dp"
android:gravity="center"
android:horizontalSpacing="10dp"
android:numColumns="auto_fit"
android:stretchMode="columnWidth"
android:verticalSpacing="10dp" />
</RelativeLayout>
gelleryitem.xml
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent" android:layout_height="fill_parent">
<ImageView android:id="@+id/thumbImage" android:layout_width="wrap_content"
android:layout_height="wrap_content" android:layout_centerInParent="true" />
<CheckBox android:id="@+id/itemCheckBox" android:layout_width="wrap_content"
android:layout_height="wrap_content" android:layout_alignParentRight="true"
android:layout_alignParentTop="true" />
</RelativeLayout>

Solution 2:
Use Universal Image Loader
https://github.com/nostra13/Android-Universal-Image-Loader.git
Give Image url as your sd card image path.
/**
*adapter class for view pager

Solution 3:
it is not possible to display particular folder images using the mediastore method. because every images stored in the mediastore has different unique id to identify it.
but you can do by create your own method to identify what are the images in the particular folder and then get the create thumbnail images.
