I´ve got a TableLayout with four TableRows and four buttons in each of the four rows.
I had big problems with different screen resolutions so I built my layout file new.
First, I give you my code:
public class MainActivity extends Activity {
Button b,b2,b3,b4, b5,b6,b7,b8,b9,b10,b11,b12,b13,b14,b15,b16,b17,b18,b19,b20;
//b21,b22,b23,b24;
ArrayList<Button> arr = new ArrayList<Button>();
MediaPlayer mp;
Button aktuell;
TextView tv;
String playtone ="";
String shouldvibra ="";
TextView tvPunktestand;
int count = 0;
CountDownTimer countdown;
CountDownTimer eins;
CountDownTimer zwei;
CountDownTimer drei;
AlertDialog.Builder alertDialog;
boolean einsstarted = false;
boolean zweistarted = false;
boolean dreistarted = false;
boolean countdownstarted = false;

Vibrator vibe;
@Override

super.onCreate(savedInstanceState);

Like you may see, my target is to set one button visible and every other invisible. Every few ms this should change.
Here is my layout file:
<TableLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="wrap_content"
android:layout_height="fill_parent"
android:background="@drawable/bg"
android:stretchColumns="0,1,2,3,4,5"
tools:context=".MainActivity" >
<TableRow
android:id="@+id/tableRow1"
android:paddingTop="22dp"
android:layout_weight="1">
<Button
android:id="@+id/button1"
android:text="1"
android:background="@drawable/willi">
</Button>
<Button
android:id="@+id/button2"
android:text="2"
android:layout_marginLeft="10dp"
android:background="@drawable/willi">
</Button>
<Button
android:id="@+id/button3"
android:text="3"
android:layout_marginLeft="10dp"

android:text="4"
android:layout_marginLeft="10dp"
android:background="@drawable/willi">

<TableRow
android:id="@+id/tableRow2"
android:layout_weight="1"

<Button
android:id="@+id/button5"
android:text="1"
android:background="@drawable/willi">
</Button>
<Button
android:id="@+id/button6"
android:text="2"
android:layout_marginLeft="10dp"
android:background="@drawable/willi">
</Button>
<Button
android:id="@+id/button7"
android:text="3"
android:layout_marginLeft="10dp"
android:background="@drawable/willi">
</Button>
<Button
android:id="@+id/button8"
android:text="4"
android:layout_marginLeft="10dp"
android:background="@drawable/willi">
</Button>
</TableRow>
and so on....
</TableLayout>
The problem is, if one button is active, it looks like this:
The buttons are lying on top of each other and they are curious stretched.
So, I tested to set all buttons visible on start, then it looks like this (How it should look - all buttons beside the other):
How is that possible that my code changes my layout file?
