Android 动态创建的表行未显示在视图中

Android 动态创建的表行未显示在视图中,android,Android,可能重复: 代码如下: DtoCbpOutcome[] outcomes = cbp.Outcomes; Log.d(_logTag, "# of outcomes: " + Integer.toString(outcomes.length)); TableLayout tl = (TableLayout) findViewById(R.id.tbl_cbp_outcomes); for (int i = 0; i < outcomes.length; i++) { // Te

可能重复:

代码如下:

DtoCbpOutcome[] outcomes = cbp.Outcomes;
Log.d(_logTag, "# of outcomes: " + Integer.toString(outcomes.length));
TableLayout tl = (TableLayout) findViewById(R.id.tbl_cbp_outcomes);
for (int i = 0; i < outcomes.length; i++) {

    // Text Views:
    // public String Description;

    TableRow tr = new TableRow(appCtx);
    tr.setLayoutParams(tbl_lay_parms);

    // Row Count
    TextView row_num = new TextView(appCtx);
    temp_string = Integer.toString(i + 1);
    row_num.setText(temp_string);
    row_num.setLayoutParams(lay_parms);
    tr.addView(row_num);

    // Description
    TextView desc = new TextView(appCtx);
    temp_string = outcomes[i].Description;
    desc.setText(temp_string);
    desc.setLayoutParams(lay_parms);
    tr.addView(desc);

    tl.addView(tr, tbl_lay_parms);
}
但是该行没有显示在布局视图(activity\u business\u plan.xml)中

我做错了什么

谢谢

我不知道是不是这样,但是:

您是否在tl.addView(tr,tbl_lay_parms)中使用“TableLayout.LayoutParams”

以及tr.setLayoutParams(tbl_lay_parms)中的“TableRow.LayoutParams”

我觉得不一样,请检查一下


致以最诚挚的问候

这看起来不错。发布保存表格的XML以及什么是
结果。长度
(大于
0
)?我已经为表格添加了XML。此外,结果长度产生5。我手动检查了结果的数量。我想查看包含TableLayout的布局。@Saifudin我检查了那篇文章,但结果没有解决我的问题。@Sam我添加了xml。谢谢
