Hi I need to have a folder where images are downloaded. Then iterate
through the contents of that folder to show images one by one for pre set
time period. My screen is divided into3 parts. in 1st row are 2 columns- 1>
list view and 2> image view 2nd row image view.Hi, My main focus is on
displaying the images.my issue is how to create the image view, since the
image resources are not in res folder of android, it is determined at run
time. ican not place image into image view with
android:src="@drawable/android"tag
public void getFromSdcard()
{
File file= new
File(android.os.Environment.getExternalStorageDirectory(),"serviceMobile2");
Toast.makeText(getBaseContext(), "file
printer",Toast.LENGTH_SHORT).show();
if (file.isDirectory())
{
listFile = file.listFiles();
for (int i = 0; i < listFile.length; i++)
{
mFileStrings[i] = listFile[i].getAbsolutePath();
f.add(listFile[i].getAbsolutePath());
System.out.println("...................................."+mFileStrings[i]);
Toast.makeText(getBaseContext(), mFileStrings[i],
Toast.LENGTH_SHORT).show();
Bitmap bitmap =
BitmapFactory.decodeFile(listFile[i].getAbsolutePath());
ImageView iv= (ImageView) findViewById(R.id.imageView2);
iv.setImageBitmap(bitmap);
}
}
}
xml file is->
<TableLayout
xmlns:android="http://schemas.android.com/apk/res/android";
android:layout_width="match_parent"
android:layout_height="match_parent"
android:stretchColumns="*" android:background="#ffffff">
