我正在完成此页面所说的内容:http://en.androidwiki.com/wiki/Dynamically_adding_rows_to_TableLayout
主要代码:
this.setContentView(R.layout.main);/* Find Tablelayout defined in main.xml */ TableLayout tl = (TableLayout)findViewById(R.id.myTableLayout); /* Create a new row to be added. */ TableRow tr = new TableRow(this); tr.setLayoutParams(new 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. */ tl.addView(tr,new TableLayout.LayoutParams( LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT)); <code>
xml:
<?xml version="1.0" encoding="utf-8"?> <TableLayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/myTableLayout" android:layout_width="fill_parent" android:layout_height="fill_parent" > <TableRow android:layout_width="fill_parent" android:layout_height="wrap_content"> <Button android:text="Static Button"/> </TableRow> </TableLayout>
但是当我复制该行时 tr.addView(B);
它给了我fc。 知道错误在哪里?答案 0 :(得分:0)
那是因为你要添加相同的按钮。试试:
.....
/* Create a Button to be the row-content. */
Button b = new Button(this);
b.setText("Dynamic Button");
b.setLayoutParams(new LayoutParams(
LayoutParams.WRAP_CONTENT,
LayoutParams.WRAP_CONTENT));
/* Add Button to row. */
tr.addView(b);
b = new Button(this);
b.setText("Another Dynamic Button");
b.setLayoutParams(new LayoutParams(
LayoutParams.WRAP_CONTENT,
LayoutParams.WRAP_CONTENT));
/* Add Button to row. */
tr.addView(b);
