Dynamically add TableRow to TableLayout
提问by dfetter88
When a button is clicked, the following method is run:
单击按钮时，将运行以下方法：
public void createTableRow(View v) {
TableLayout tl = (TableLayout) findViewById(R.id.spreadsheet);
TableRow tr = new TableRow(this);
LayoutParams lp = new LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT);
tr.setLayoutParams(lp);
TextView tvLeft = new TextView(this);
tvLeft.setLayoutParams(lp);
tvLeft.setBackgroundColor(Color.WHITE);
tvLeft.setText("OMG");
TextView tvCenter = new TextView(this);
tvCenter.setLayoutParams(lp);
tvCenter.setBackgroundColor(Color.WHITE);
tvCenter.setText("It");
TextView tvRight = new TextView(this);
tvRight.setLayoutParams(lp);
tvRight.setBackgroundColor(Color.WHITE);
tvRight.setText("WORKED!!!");
tr.addView(tvLeft);
tr.addView(tvCenter);
tr.addView(tvRight);
tl.addView(tr, new TableLayout.LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT));
}
R.id.spreadsheetis an xml TableLayout. I can see from debugging that the method is being accessed, but nothing is drawn to the screen. What gives? Do I need to reset the Content View somehow?
R.id.spreadsheet是一个 xml TableLayout。我可以从调试中看到该方法正在被访问，但没有任何内容被绘制到屏幕上。是什么赋予了？我需要以某种方式重置内容视图吗？

As it turns out, Eclipse is not always right. Ctrl+Shift+M made the wrong import. It had import android.view.ViewGroup.LayoutParamswhen it should have import android.widget.TableRow.LayoutParams
事实证明，Eclipse 并不总是正确的。Ctrl+Shift+M 导入错误。它import android.view.ViewGroup.LayoutParams应该有import android.widget.TableRow.LayoutParams
Everything works fine now.
现在一切正常。
