问题描述
我有一个小应用程序，需要定期添加到tablelayout表行。每getChildCount（）方法的行被添加，但它不显示。任何建议将不胜AP preciated
TableLayout TBL =（TableLayout）findViewById（R.id.mytbl）;
连续的TableRow =新的TableRow（本）;
LL的LinearLayout =新的LinearLayout（本）;
TextView的txtView =新的TextView（本）;
row.setId（1234）;
row.setLayoutParams（新TableRow.LayoutParams（TableRow.LayoutParams.WRAP_CONTENT，TableRow.LayoutParams.WRAP_CONTENT））;
row.setGravity（Gravity.CENTER）;
row.setBackgroundResource（android.R.color.darker_gray）;
LinearLayout.LayoutParams LP =新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）; 弦乐味精=示例文本; txtView.setId（657）;
txtView.setLayoutParams（新的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（Ⅱ）;
tbl.addView（行，新TableLayout.LayoutParams（TableLayout.LayoutParams.FILL_PARENT，TableLayout.LayoutParams.WRAP_CONTENT））; //可能与布局添加此PARAMS tl.addView（TR，新TableLayout.LayoutParams（LayoutParams.FILL_PARENT，的LayoutParams。 WRAP_CONTENT））;
我试过tbl.RequestLayout（）和tbl.Invalidate（），但没有帮助。该表是包裹在一个滚动视图这是我最好的猜测，问题出在哪里。我一直在摆弄这几个小时，以便在正确的方向轻推肯定会有所帮助。
＆LT;滚动型
机器人：ID =@ + ID / scrVw_lst
机器人：layout_width =match_parent
机器人：layout_height =WRAP_CONTENT
＆GT; ＆LT; TableLayout
机器人：ID =@ + ID / MYTBL
机器人：layout_width =match_parent
机器人：layout_height =WRAP_CONTENT
机器人：stretchColumns =*＆GT;
你有没有运行code在添加行的 TableLayout ？我模拟了一个按钮中点击添加行，我得到0 异常的尴尬鸿沟。
总之，改变的LayoutParams 封闭的LinearLayout 来的 TableRow.LayoutParams （其父是的TableRow ）
TableRow.LayoutParams LP =新TableRow.LayoutParams（
TableRow.LayoutParams.FILL_PARENT，
TableRow.LayoutParams.WRAP_CONTENT，1.0F）;
ll.setId（1589）;
ll.setLayoutParams（LP）
另外，如果这不能解决问题，尝试添加：
的android：fillViewport =真
在XML布局中的滚动型标记。
I have a small app that periodically needs a table row added to the tablelayout. Per the getChildCount() method the row is being added but it doesn't display. Any suggestions would be greatly appreciated
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));
i've tried tbl.RequestLayout() and tbl.Invalidate() but no help. The table is wrapped in a scrollview which is my best guess as to where the problem is. I've been tinkering with this for several hours so a nudge in the right direction sure would be helpful
<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="*">
Have you run the code for adding a row in your TableLayout? I've simulated adding a row on a click of a Button and I get a awkward Divide by 0 exception.
Anyway, change the LayoutParams of the enclosing Linearlayout to TableRow.LayoutParams(its parent is the TableRow):
TableRow.LayoutParams lp = new TableRow.LayoutParams(
TableRow.LayoutParams.FILL_PARENT,
TableRow.LayoutParams.WRAP_CONTENT, 1.0f);
ll.setId(1589);
ll.setLayoutParams(lp)
Also, if this doesn't solve the problem, try to add:
android:fillViewport="true"
to the ScrollView tag in the xml layout.
