XML で TableLayout を初期化し、プログラムで入力しようとしています。これが私の XML、Java、および LogCat の出力です。
ハイスコア.java
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);
}
});
}
}

私が欲しいのは、行1の見出しが「RANK」、「PERCENTAGE」、および「SCORE」である単純な3列のテーブルです。後で、SQLite データベースから取得する行をさらに 10 行用意しますが、後で対処します。
