问题描述
我正在尝试按照此处
/* Find Tablelayout defined in main.xml */
TableLayout tl = (TableLayout) findViewById(R.id.SaleOrderLines);
/* Create a new row to be added. */
TableRow tr = new TableRow(this);
tr.setLayoutParams(new TableRow.LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT));
/* Create a Button to be the row-content. */
Button b = new Button(this);
b.setText("Dynamic Button");
b.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT));
/* Add Button to row. */
tr.addView(b);
/* Add row to TableLayout. */
//tr.setBackgroundResource(R.drawable.sf_gradient_03);
tl.addView(tr, new TableLayout.LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT));
但是屏幕上没有绘制任何内容.(与此处中提到的一样)
But but nothing is drawn to the screen. (same as one mentioned here)
当我添加 tr.setBackgroundResource(R.drawable.sf_gradient_03);
时,绘制了带有背景图像的行而不是按钮
When i added tr.setBackgroundResource(R.drawable.sf_gradient_03);
, the row with the background image is drawn but not the button
这是我的布局
<!-- Sale Order Lines START -->
<LinearLayout android:id="@+id/SaleOrderLinesArea" android:orientation="vertical"

推荐答案
明白了,每个 LayoutParams
都应该是 android.widget.TableRow.LayoutParams
除了提供的一个tl.addView(...)
Got it, every LayoutParams
should be of android.widget.TableRow.LayoutParams
except one that supplied to tl.addView(...)
/* Find Tablelayout defined in main.xml */
TableLayout tl = (TableLayout) findViewById(R.id.SaleOrderLines);
/* Create a new row to be added. */
TableRow tr = new TableRow(this);
tr.setLayoutParams(new TableRow.LayoutParams(TableRow.LayoutParams.FILL_PARENT, TableRow.LayoutParams.WRAP_CONTENT));
/* Create a Button to be the row-content. */
Button b = new Button(this);
b.setText("Dynamic Button");
b.setLayoutParams(new TableRow.LayoutParams(TableRow.LayoutParams.FILL_PARENT, TableRow.LayoutParams.WRAP_CONTENT));
/* Add Button to row. */
tr.addView(b);
/* Add row to TableLayout. */
//tr.setBackgroundResource(R.drawable.sf_gradient_03);
tl.addView(tr, new TableLayout.LayoutParams(TableLayout.LayoutParams.FILL_PARENT, TableLayout.LayoutParams.WRAP_CONTENT));
