[android-developers] dynamic image display

-1 down vote favorite

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">     <!-- Row 1 with single column -->      <TableRow          android:layout_height="wrap_content"         android:layout_width="wrap_content"         android:gravity="center_horizontal">     <EditText     android:id="@+id/personal_contacts"     android:layout_width="200dip"     android:layout_height="wrap_content"     android:hint="number"     android:inputType="number"     android:imeOptions="actionSend" />     <TableRow          android:layout_height="wrap_content"         android:layout_width="wrap_content"         android:gravity="center_horizontal">      <Button         android:id="@+id/button1"         style="?android:attr/buttonStyleSmall"         android:layout_width="wrap_content"         android:layout_height="wrap_content"         android:layout_alignParentRight="true"         android:layout_alignParentTop="true"         android:text="Save" />      </TableRow>       <TableRow          android:layout_height="wrap_content"         android:layout_width="wrap_content"         android:gravity="center_horizontal">     <Button         android:id="@+id/button2"         style="?android:attr/buttonStyleSmall"         android:layout_width="wrap_content"         android:layout_height="wrap_content"         android:layout_alignParentRight="true"         android:layout_alignParentTop="true"         android:text="Delete" />     </TableRow>     </TableRow>     <TableRow          android:layout_height="wrap_content"         android:layout_width="wrap_content"         android:gravity="center_horizontal">       <ListView         android:id="@+id/list2"         android:layout_width="match_parent"         android:layout_height="wrap_content" >     </ListView>       <ImageView         android:id="@+id/imageView1"         android:layout_width="wrap_content"         android:layout_height="wrap_content"          />          </TableRow>           <TableRow          android:layout_height="wrap_content"         android:layout_width="wrap_content"         android:gravity="center_horizontal">       <ImageView         android:id="@+id/imageView2"         android:layout_width="wrap_content"         android:layout_height="wrap_content"          />       </TableRow>     </TableLayout> I ran the debugger. control does not go into if (file.isDirectory()) ?????????????
