我有下一个布局（TOP：两个Spinner Half：TableLayout Down：Button），我用TableService填充了TableLayout ... “for（int i = 0; i＆lt; ljsonArray.length（）; i ++）”
但是当TableService的最后一条记录显示在TableLayout中时，按钮消失了，出了什么问题？
此致
//Click botton
public void consultar(View v){
// Building Parameters to call WebService
List<NameValuePair> params = new ArrayList<NameValuePair>();
String url = "http://futcho7.com.mx/MiScore/WebService/gettablapos.php";
params.add(new BasicNameValuePair("id_cliente", numCte.get(0)));
params.add(new BasicNameValuePair("id_sucursal", numSuc.get(0)));
params.add(new BasicNameValuePair("id_torneo", Integer.toString(idTorneo)));
params.add(new BasicNameValuePair("id_jornada", Integer.toString(idJornada)));
new AsyncConector(this, url, params, this).execute();
}

答案 0 :(得分：0)
您的按钮实际位于tableLayout的右侧。 将linearlayout的方向更改为Vertical而不是horizontal。
此外，如果你想在scrollview的末尾看到它，buttonView应该是scrollview的一部分。
您还可以在相对布局中嵌套所有xml，并将属性“android：layout_alignParentBottom =”true“添加到按钮，按钮将始终可见。
希望这有帮助。
EDIT-1：
你有没有试过像

当我直接在xml中添加行时，它适用于我。
