我在 xml 中创建了一个 TableLayout。现在我想在我的活动的 onCreate() 中以编程方式添加一个表格行。方法 fillTable 应该可以完成这项工作，但 TableRow 没有显示在表格中。
这是我的代码：
在活动中：
public void fillTable() {
t1 = (TableLayout) findViewById(R.id.tabelle);
TableRow tr = new TableRow(this);
tr.setLayoutParams(new TableRow.LayoutParams(
TableRow.LayoutParams.FILL_PARENT,
TableRow.LayoutParams.FILL_PARENT));
TextView rang = new TextView(this);
TextView mannschaftsname = new TextView(this);
TextView spiele = new TextView(this);
TextView siege = new TextView(this);
TextView unentschieden = new TextView(this);
TextView niederlagen = new TextView(this);
TextView tore = new TextView(this);
TextView doppelpunkt = new TextView(this);
TextView gegentore = new TextView(this);
TextView differenz = new TextView(this);
TextView punkte = new TextView(this);
rang.setLayoutParams(new TableRow.LayoutParams(
TableRow.LayoutParams.WRAP_CONTENT,
TableRow.LayoutParams.WRAP_CONTENT));
rang.setGravity(Gravity.CENTER_HORIZONTAL);
rang.setPadding(1, 1, 1, 1);
rang.setText("0");
rang.setTextColor(R.color.white);
mannschaftsname.setLayoutParams(new TableRow.LayoutParams(
TableRow.LayoutParams.WRAP_CONTENT,
TableRow.LayoutParams.WRAP_CONTENT));
mannschaftsname.setGravity(Gravity.CENTER_HORIZONTAL);
mannschaftsname.setPadding(1, 1, 1, 1);
mannschaftsname.setText("TEST");
mannschaftsname.setTextColor(R.color.white);
spiele.setLayoutParams(new TableRow.LayoutParams(
TableRow.LayoutParams.WRAP_CONTENT,
TableRow.LayoutParams.WRAP_CONTENT));
spiele.setGravity(Gravity.CENTER_HORIZONTAL);
spiele.setPadding(1, 1, 1, 1);
spiele.setText("0");
spiele.setTextColor(R.color.white);
siege.setLayoutParams(new TableRow.LayoutParams(
TableRow.LayoutParams.WRAP_CONTENT,
TableRow.LayoutParams.WRAP_CONTENT));
siege.setGravity(Gravity.CENTER_HORIZONTAL);
siege.setPadding(1, 1, 1, 1);
siege.setText("0");
siege.setTextColor(R.color.white);
unentschieden.setLayoutParams(new TableRow.LayoutParams(
TableRow.LayoutParams.WRAP_CONTENT,
TableRow.LayoutParams.WRAP_CONTENT));
unentschieden.setGravity(Gravity.CENTER_HORIZONTAL);
unentschieden.setPadding(1, 1, 1, 1);
unentschieden.setText("0");
unentschieden.setTextColor(R.color.white);
niederlagen.setLayoutParams(new TableRow.LayoutParams(
TableRow.LayoutParams.WRAP_CONTENT,
TableRow.LayoutParams.WRAP_CONTENT));
niederlagen.setGravity(Gravity.CENTER_HORIZONTAL);
niederlagen.setPadding(1, 1, 1, 1);
niederlagen.setText("0");
niederlagen.setTextColor(R.color.white);
tore.setLayoutParams(new TableRow.LayoutParams(
TableRow.LayoutParams.WRAP_CONTENT,
TableRow.LayoutParams.WRAP_CONTENT));
tore.setGravity(Gravity.CENTER_HORIZONTAL);
tore.setPadding(1, 1, 1, 1);
tore.setText("0");
tore.setTextColor(R.color.white);
doppelpunkt.setLayoutParams(new TableRow.LayoutParams(
TableRow.LayoutParams.WRAP_CONTENT,
TableRow.LayoutParams.WRAP_CONTENT));
doppelpunkt.setGravity(Gravity.CENTER_HORIZONTAL);
doppelpunkt.setPadding(1, 1, 1, 1);
doppelpunkt.setText(":");
doppelpunkt.setTextColor(R.color.white);
gegentore.setLayoutParams(new TableRow.LayoutParams(
TableRow.LayoutParams.WRAP_CONTENT,
TableRow.LayoutParams.WRAP_CONTENT));
gegentore.setGravity(Gravity.CENTER_HORIZONTAL);
gegentore.setPadding(1, 1, 1, 1);
gegentore.setText("0");
gegentore.setTextColor(R.color.white);
differenz.setLayoutParams(new TableRow.LayoutParams(
TableRow.LayoutParams.WRAP_CONTENT,
TableRow.LayoutParams.WRAP_CONTENT));
differenz.setGravity(Gravity.CENTER_HORIZONTAL);
differenz.setPadding(1, 1, 1, 1);
differenz.setText("0");
differenz.setTextColor(R.color.white);
punkte.setLayoutParams(new TableRow.LayoutParams(
TableRow.LayoutParams.WRAP_CONTENT,
TableRow.LayoutParams.WRAP_CONTENT));
punkte.setGravity(Gravity.CENTER_HORIZONTAL);
punkte.setPadding(1, 1, 1, 1);
punkte.setText("0");
punkte.setTextColor(R.color.white);
tr.addView(rang);
tr.addView(mannschaftsname);
tr.addView(spiele);
tr.addView(siege);
tr.addView(unentschieden);
tr.addView(niederlagen);
tr.addView(tore);
tr.addView(doppelpunkt);
tr.addView(gegentore);
tr.addView(differenz);
tr.addView(punkte);
t1.addView(tr, new TableRow.LayoutParams(
TableRow.LayoutParams.FILL_PARENT,
TableRow.LayoutParams.WRAP_CONTENT));
}
