Android Tutorial : Set ImageView file from SD Card

Bitmap bmp = BitmapFactory.decodeFile(Environment.getExternalStorageDirectory()
+ strStoragePath+strLocalFileName+strJPGext);
ivThumbnailPlaceHolder.setImageBitmap(bmp);

That is the code.

This “Environment.getExternalStorageDirectory()+ strStoragePath+strLocalFileName+strJPGext” actually meant the file path, for example : “mnt/sdcard/yourfolder/blabla.jpg”.

you can add this

//remove title bar this.requestWindowFeature(Window.FEATURE_NO_TITLE);

setContentView(R.layout.main);

make sure the line is before layout declaration or your app will crash

create new class

public class basicdisplayoption {
public static void toggleStatusBar(Activity myActivityReference, boolean boolYesNo) {
if(boolYesNo == true)
{
WindowManager.LayoutParams attrs = myActivityReference.getWindow().getAttributes();
attrs.flags &= ~WindowManager.LayoutParams.FLAG_FULLSCREEN;
myActivityReference.getWindow().setAttributes(attrs);
}
else
{
WindowManager.LayoutParams attrs = myActivityReference.getWindow().getAttributes();
attrs.flags |= WindowManager.LayoutParams.FLAG_FULLSCREEN;
myActivityReference.getWindow().setAttributes(attrs);
}
}
}

and
at activity onCreate, to turn on status bar, call
basicdisplayoption.toggleStatusBar(sinarmasmsiglife.this, true);
to turn off :
basicdisplayoption.toggleStatusBar(sinarmasmsiglife.this, false);
