在安卓中调整动态TableLayout的大小
在安卓中调整动态TableLayout的大小
提问于 2017-08-15 15:56:33
我已经在Android中创建了一个动态TableLayout。问题是，列中有一个不必要的间隙。我想删除它，我已经修改了几次代码，但结果令人惊讶。这是我目前所能得到的最好的。
正如您所看到的，标题中有一个间隙，如果行包含2+行，则行中也有一个间隙。我想让第一列(即Items)具有最长的宽度，而另一列只包含标题的内容。
这是XML
<TableLayout
android:id="@+id/tableDescription"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:stretchColumns="*">
<TableRow
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:weightSum="4">
<TextView
android:layout_width="@dimen/size0"
android:layout_height="match_parent"
android:layout_weight="1"
android:background="@drawable/cell_shape"
android:padding="@dimen/size5"
android:text="@string/items" />
<TextView
android:layout_width="@dimen/size0"
android:layout_height="match_parent"
android:layout_weight="1"
android:background="@drawable/cell_shape"
android:padding="@dimen/size5"
android:text="@string/quantity" />
<TextView
android:layout_width="@dimen/size0"
android:layout_height="match_parent"
android:layout_weight="1"
android:background="@drawable/cell_shape"
android:padding="@dimen/size5"
android:text="@string/unitPrice" />
<TextView
android:layout_width="@dimen/size0"
android:layout_height="match_parent"
android:layout_weight="1"
android:background="@drawable/cell_shape"
android:padding="@dimen/size5"
android:text="@string/total" />
</TableRow>
</TableLayout>下面是生成动态行的代码
private void init() {
// Array for item
String[] valuesItem = new String[] {
"Room asd",
"Room qwewq",
"Room kadskadskl",
"Room oeqwoeqwo",
"Room uuawuwauaw" };
final ArrayList<String> listItem = new ArrayList<String>();
for (int i = 0; i < valuesItem.length; ++i) {
listItem.add(valuesItem[i]);
}
// Array for quantity
String[] valuesQuantity = new String[] {
"1",
"1",
"2",
"1",
"2" };
final ArrayList<String> listQuantity = new ArrayList<String>();
for (int i = 0; i < valuesQuantity.length; ++i) {
listQuantity.add(valuesQuantity[i]);
}
// Array for price
String[] valuesPrice = new String[] {
"10",
"10",
"20",
"50",
"30" };
final ArrayList<String> listPrice = new ArrayList<String>();
for (int i = 0; i < valuesPrice.length; ++i) {
listPrice.add(valuesPrice[i]);
}
// Array for total
String[] valuesTotal = new String[] {
"10",
"10",
"40",
"50",
"60" };
final ArrayList<String> listTotal = new ArrayList<String>();
for (int i = 0; i < valuesTotal.length; ++i) {
listTotal.add(valuesTotal[i]);
}
for (int i = 0; i <valuesItem.length; i++) {
TableRow row= new TableRow(getActivity());
TableRow.LayoutParams lp = new TableRow.LayoutParams(TableRow.LayoutParams.MATCH_PARENT, TableRow.LayoutParams.MATCH_PARENT);
row.setLayoutParams(lp);
TextView item = new TextView(getActivity());
TextView quantity = new TextView(getActivity());
TextView price = new TextView(getActivity());
TextView total = new TextView(getActivity());
item.setText(valuesItem[i]);
quantity.setText(valuesQuantity[i]);
price.setText(valuesPrice[i]);
total.setText(valuesTotal[i]);
item.setPadding(getActivity().getResources().getDimensionPixelSize(R.dimen.size5),
getActivity().getResources().getDimensionPixelSize(R.dimen.size5),
(getActivity().getResources().getDimensionPixelSize(R.dimen.size5)),
getActivity().getResources().getDimensionPixelSize(R.dimen.size5));
quantity.setPadding(getActivity().getResources().getDimensionPixelSize(R.dimen.size5),
getActivity().getResources().getDimensionPixelSize(R.dimen.size5),
getActivity().getResources().getDimensionPixelSize(R.dimen.size5),
getActivity().getResources().getDimensionPixelSize(R.dimen.size5));
price.setPadding(getActivity().getResources().getDimensionPixelSize(R.dimen.size5),
getActivity().getResources().getDimensionPixelSize(R.dimen.size5),
getActivity().getResources().getDimensionPixelSize(R.dimen.size5),
getActivity().getResources().getDimensionPixelSize(R.dimen.size5));
total.setPadding(getActivity().getResources().getDimensionPixelSize(R.dimen.size5),
getActivity().getResources().getDimensionPixelSize(R.dimen.size5),
getActivity().getResources().getDimensionPixelSize(R.dimen.size5),
getActivity().getResources().getDimensionPixelSize(R.dimen.size5));
item.setWidth(getActivity().getResources().getDimensionPixelSize(R.dimen.size0));
quantity.setWidth(getActivity().getResources().getDimensionPixelSize(R.dimen.size0));
price.setWidth(getActivity().getResources().getDimensionPixelSize(R.dimen.size0));
total.setWidth(getActivity().getResources().getDimensionPixelSize(R.dimen.size0));
item.setBackgroundResource(R.drawable.cell_shape);
quantity.setBackgroundResource(R.drawable.cell_shape);
price.setBackgroundResource(R.drawable.cell_shape);
total.setBackgroundResource(R.drawable.cell_shape);
row.addView(item);
row.addView(quantity);
row.addView(price);
row.addView(total);
tableDynamic.addView(row);
}
}抱歉，如果有点乱的话。谢谢!

通过为每个TextView配置LayoutParams来解决
lp = new TableRow.LayoutParams(0, TableRow.LayoutParams.MATCH_PARENT, 5f);
item.setLayoutParams(lp);
lp = new TableRow.LayoutParams(0, TableRow.LayoutParams.MATCH_PARENT, 2f);
quantity.setLayoutParams(lp);
lp = new TableRow.LayoutParams(0, TableRow.LayoutParams.MATCH_PARENT, 1.5f);
price.setLayoutParams(lp);
lp = new TableRow.LayoutParams(0, TableRow.LayoutParams.MATCH_PARENT, 1.5f);
total.setLayoutParams(lp);页面原文内容由Stack Overflow提供。腾讯云小微IT领域专用引擎提供翻译支持
