下列TableLayout
完全符合我的要求(它填充其父级并且列均匀拉伸):
<?xml version="1.0" encoding="utf-8"?>
<TableLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#7434a6" >
<TableRow
android:layout_width="fill_parent"
android:layout_height="0px"
android:layout_weight="1" >
<TextView
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_weight="1"
android:background="#836492" />
<TextView
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_weight="1"
android:background="#103456" />
</TableRow>
<TableRow
android:layout_width="fill_parent"
android:layout_height="0px"
android:layout_weight="1" >
<TextView
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_weight="1"
android:background="#958453" />
<TextView
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_weight="1"
android:background="#756aa9" />
</TableRow>
</TableLayout>
但是,由于我希望行数可配置,因此我开始以编程方式创建布局:
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
Context context = getActivity();
TableLayout.LayoutParams tableParams =
new TableLayout.LayoutParams(TableLayout.LayoutParams.MATCH_PARENT,
TableLayout.LayoutParams.MATCH_PARENT);
TableRow.LayoutParams rowParams =
new TableRow.LayoutParams(TableRow.LayoutParams.MATCH_PARENT, 0, 1f);
TableRow.LayoutParams itemParams =
new TableRow.LayoutParams(TableRow.LayoutParams.MATCH_PARENT,
TableRow.LayoutParams.MATCH_PARENT, 1f);
TableLayout tableLayout = new TableLayout(context);
tableLayout.setLayoutParams(tableParams);
tableLayout.setBackgroundColor(0xff7434a6);
for (int row = 0; row < 2; row++) {
TableRow tableRow = new TableRow(context);
tableRow.setLayoutParams(rowParams);
for (int column = 0; column < 2; column++) {
Random color = new Random();
int randomColor =
Color.argb(255, color.nextInt(256),
color.nextInt(256),
color.nextInt(256));
TextView textView = new TextView(context);
textView.setLayoutParams(itemParams);
textView.setBackgroundColor(randomColor);
tableRow.addView(textView);
}
tableLayout.addView(tableRow);
}
return tableLayout;
}
在某种程度上,这也很有效。我唯一的问题是,我的桌子垂直折叠:
这里有什么问题吗?我认为我的代码与 XML 的作用相同。我进行了很多搜索和尝试,但没有得到正确的想法。
