Question

Ok so i’ve written my main xml file and i’m pretty sure its correct, but I dont know how to display my layout on the screen. I tried creating variables for all the different widgets and setting them to the same as in the R.id.main but it didnt show anything on screen. basically i don’t understand how to display what ive got in xml on screen. This is my code, please can someone explain where i’m going wrong.

public class MinesweeperActivity extends Activity {

private TableLayout all;

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    all = (TableLayout)findViewById(R.id.all);

    }
}

// this is my xml

<?xml version="1.0" encoding="utf-8"?>
<TableLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/all"
android:stretchColumns="*" 
android:background="@drawable/bground"

<TableRow>
    <TextView
    android:id="@+id/Timer"
    android:layout_column="0"
    android:text="000" />
     <TextView
    android:id="@+id/Counter"
    android:layout_column="2"
    android:text="000" />  
    <ImageButton 
    android:id="@+id/Face"
    android:layout_column="1"
    android:background="@drawable/faces"
    android:layout_height="50px" />
</TableRow>
<TableRow>
    <TextView                      
        android:layout_column="0"
        android:layout_height="50px"
        android:layout_span="3"
        android:padding="10dip"/>

I tried with your code and i found the error in logcat is **java.lang.RuntimeException: Binary XML file line #2: You must supply a layout_width attribute.** I think the mistake is this..Try once it may solve your problem.You must give layout widh and height attributes to the table layout.

<TableLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/all"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:background="@drawable/bground"
    android:stretchColumns="*" >
