您不应该使用在布局 XML 中定义的项目来创建它的更多实例.您应该在单独的 XML 中创建它并对其进行扩充,或者以编程方式创建 TableRow.如果以编程方式创建它们,应该是这样的:
You shouldn't be using an item defined in the Layout XML in order to create more instances of it. You should either create it in a separate XML and inflate it or create the TableRow programmaticaly. If creating them programmaticaly, should be something like this:
public void init(){
TableLayout ll = (TableLayout) findViewById(R.id.displayLinear);
for (int i = 0; i <2; i++) {
TableRow row= new TableRow(this);
TableRow.LayoutParams lp = new TableRow.LayoutParams(TableRow.LayoutParams.WRAP_CONTENT);
row.setLayoutParams(lp);
checkBox = new CheckBox(this);
tv = new TextView(this);
addBtn = new ImageButton(this);
addBtn.setImageResource(R.drawable.add);
minusBtn = new ImageButton(this);
minusBtn.setImageResource(R.drawable.minus);
qty = new TextView(this);
checkBox.setText("hello");
qty.setText("10");
row.addView(checkBox);
row.addView(minusBtn);
row.addView(qty);
row.addView(addBtn);
ll.addView(row,i);
}
}
