Question

我有一个小应用程序，需要定期将表格行添加到tablelayout。根据getChildCount（）方法，正在添加行但不显示该行。任何建议将不胜感激

    TableLayout tbl = (TableLayout)findViewById(R.id.mytbl);
    TableRow row = new TableRow(this);
    LinearLayout ll = new LinearLayout(this);
    TextView txtView = new TextView(this);


    row.setId(1234);
    row.setLayoutParams(new TableRow.LayoutParams(TableRow.LayoutParams.WRAP_CONTENT,TableRow.LayoutParams.WRAP_CONTENT));
    row.setGravity(Gravity.CENTER);
    row.setBackgroundResource(android.R.color.darker_gray);


    LinearLayout.LayoutParams lp = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.FILL_PARENT, LinearLayout.LayoutParams.WRAP_CONTENT,1.0f);
    ll.setId(1589);
    ll.setLayoutParams(lp); 
    ll.setOrientation(LinearLayout.VERTICAL);
    ll.setBackgroundResource(R.color.header_background);
    ll.setGravity(Gravity.CENTER);

    String msg = "Sample Text";

    txtView.setId(657);
    txtView.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT,LayoutParams.WRAP_CONTENT));
    txtView.setTextColor(R.color.a_color);
    txtView.setBackgroundResource(R.drawable.border_a);
    txtView.setGravity(Gravity.TOP | Gravity.LEFT);
    txtView.setText(msg);


    ll.addView(txtView);
    row.addView(ll);
    tbl.addView(row,new TableLayout.LayoutParams(TableLayout.LayoutParams.FILL_PARENT, TableLayout.LayoutParams.WRAP_CONTENT));//maybe add this with layout params tl.addView(tr,new TableLayout.LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT));

我已尝试过tbl.RequestLayout（）和tbl.Invalidate（）但没有帮助。该表包含在一个滚动视图中，这是我最好的猜测问题所在。我几个小时一直在修补这个问题，所以在正确的方向上轻推确定会有所帮助

    <ScrollView
    android:id="@+id/scrVw_lst"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
     >

    <TableLayout
        android:id="@+id/mytbl"
        android:layout_width="match_parent"
        android:layout_height="wrap_content" 
        android:stretchColumns="*">

您是否运行了在TableLayout中添加行的代码？我已经模拟了在点击Button时添加一行，我得到了一个尴尬的Divide by 0例外。

无论如何，将封闭式LayoutParams的{{1}}更改为Linearlayout（其父级为TableRow.LayoutParams）：

TableRow

此外，如果这不能解决问题，请尝试添加：

    TableRow.LayoutParams lp = new TableRow.LayoutParams(
            TableRow.LayoutParams.FILL_PARENT,
            TableRow.LayoutParams.WRAP_CONTENT, 1.0f);
    ll.setId(1589);
    ll.setLayoutParams(lp)

到xml布局中的android:fillViewport="true"标记。

正在添加TableRow但不显示
