I am trying to initialize a TableLayout in XML and then fill it in programmatically. Here is my XML, java and LogCat output.Highscores.java\[code\]public class Highscores extends Activity { TableLayout table; TableRow rowHeader, row1, row2, row3, row4, row5, row6, row7, row8, row9, row10; TextView rank, percentage, score; Button btn1; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.highscoresmain); TableLayout table = (TableLayout)findViewById(R.id.tableLayout); TextView rank = (TextView)findViewById(R.id.rank); rank.setText("RANK"); TextView percentage = (TextView)findViewById(R.id.percentage); percentage.setText("PERCENTAGE"); TextView score = (TextView)findViewById(R.id.score); score.setText("SCORE"); TableRow rowHeader = (TableRow)findViewById(R.id.rowHeader); rowHeader.addView(rank); //Line 39 rowHeader.addView(percentage); rowHeader.addView(score); Button btn1 = (Button)findViewById(R.id.homeBtn); table.addView(rowHeader, new TableLayout.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT)); btn1.setOnClickListener(new OnClickListener() { public void onClick(View arg0) { Intent intent = new Intent(Highscores.this, MainMenu.class); startActivity(intent); } }); }}\[/code\]highscoresmain.xml\[code\]<TableLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:id = "@+id/tableLayout" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_weight="0" android
