rotating text,marquee is not appropriate

I have added this code to my MainActivity.java:
tv6.setText("11111111111\n"+strPokus2+"\nA\n"+strPokus+"\nB");
tv6.setSingleLine(true);
tv6.setMarqueeRepeatLimit(-1);
tv6.setEllipsize(TextUtils.TruncateAt.MARQUEE);
tv6.setSelected(true);
HOWEVER, the text is still static, not rotating/moving. What's wrong ??

When I run this program on my phone, it works perfectly on the first activity. When I click the button to switch to the second activity, which should be displaying in TextViews the data I've recorded, the screen is just white. I can see the Android bar on the top where I see my service and battery life, etc, but it is even kinda blurred out a bit as if something is laying over the top of it.
The only reason I have the ListView is because the compiler demanded I have it in the code. I don't want/need it, but apparently the compiler thinks I do.
What am I doing wrong here? I want to display the recorded data on the second activity... so, we calculate the clicks on the turret, shoot the rifle, and record that data to a file if it's a good shot, then all we should have to do is come back to the second activity and view the data we've recorded from all our previous shots at varying ranges.
Anyone? Been at this all day.
Thanks!

Same thing is still occurring after removing the extends ListActivity and the ListView from the XML.

The ListView is demanded because you are extending ListActivity. Also, the ListView blocks your TextView so you couldn't see it.
However, you should use stick in using ListView since you are displaying multiple textviews with a dynamic number. See this for a tutorial.
If you don't want to use it then change
public class RangeRecords extends ListActivity
to
public class RangeRecords extends AppCompatActivity
Remove ListView on your layout

Android Layout help needed

I am having difficulty making my layout to work...
What I want to do is have two spinners and a button below those and once the button is clicked, I display the results based on the values selected in the spinners.
-----------
| Spinner 1 |
-----------
-----------
| Spinner 2 |
-----------
-----------
| Button |
-----------
Result 1
Result 2
Result 3
Result 4
Result 5
I have tried to put the results in a ListView, but the problem I face is that once the button is clicked, I can see the repetition of Spinner1, Spinner2 and the Button itself multiple times.

The adapter is as follows:
package ms.timetable;
import java.util.ArrayList;
import ms.timetable.MainActivity.TimeTable;
import android.content.Context;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ArrayAdapter;
import android.widget.TextView;
public class TimetableAdapter extends ArrayAdapter<TimeTable>{
private final Context context;
private final ArrayList<TimeTable> values;
public TimetableAdapter(Context context, ArrayList<TimeTable> values){
super(context, R.layout.activity_main, values);
this.context = context;
this.values = values;
}
public View getView(int position, View convertView, ViewGroup parent) {
LayoutInflater inflater = (LayoutInflater) context
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View rowView = inflater.inflate(R.layout.activity_main, parent, false);
TextView textView = (TextView) rowView.findViewById(R.id.textView1);
TextView textView2 = (TextView) rowView.findViewById(R.id.textView2);
//System.err.println("Position is : "+position);
TimeTable tt = values.get(position);
textView.setText(tt.get_departure());
textView2.setText(tt.get_arrival());
return rowView;
}
}

The problem is due to
View rowView = inflater.inflate(R.layout.activity_main, parent, false);
in getView() method.
You are inflating whole activity_main in a row and then adding it to a listview.
Put a row for results in separate xml instead of activity_main. So you will have a new xml file say, row.xml which will contain:
<TextView
android:id="#+id/textView2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/hello_world"
android:textColor="#ff0000"
android:textSize="12sp" />
<TextView
android:id="#+id/textView1"
android:layout_width="wrap_content"
android:layout_height="fill_parent"
android:contentDescription="#string/hello_world"
android:gravity="center_vertical"
android:text="#string/hello_world"
android:textColor="#0000ff"
android:textSize="12sp" />
So you will have to inflate as
View rowView = inflater.inflate(R.layout.row, parent, false);
And then add the generated rows in the listview which is in activity_main.xml.
So your problem will be solved. Hope it helps.

Scrolling is not perform in Listview in android

I have a problem that, I am adding listview in LinearLayout dynamically through code and set the EndlessAdapter into that, Data is shown correctly but we are unable to scroll from top to bottom in the list. I don't know why? please suggest me any solution regarding the same.

Android code to record a video using remote IP camera which is accessed by using a url

Here are some links which tell about video recording:
How can I capture a video recording on Android?
https://github.com/churnlabs/android-ffmpeg-sample
and there are also many links which tell about video recording but got no any clue how to use the remote IP camera to record video.
By using different samples on stackoverflow I become able to take picture and save on sdcard but couldn't record video.
If any one has any idea or code along with required files I will be thankful.
For example the url I am using where the IP camera is available is given below:
http://trackfield.webcam.oregonstate.edu/axis-cgi/mjpg/video.cgi?resolution=800x600&amp%3bdummy=1333689998337
