我正在尝试构建一个动态填充表。我知道了，但我的问题是添加的单元格与标题栏的宽度不匹配。
我怎样才能做到这一点？
布局.xml

动态添加：
private void printTimeline() {
Log.d(CLASSTAG, "printTimeline");
TableLayout timelineTable = (TableLayout) ParentActivity.findViewById(R.id.timelineTable);
Log.d(CLASSTAG, "we have: " + this.timelineEvents.size() + " events to add");
for (PlantEvent event : this.timelineEvents) {
TableRow tr = new TableRow(ParentActivity);
LayoutParams lp = new LayoutParams(LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT);
tr.setLayoutParams(lp);
for (int j = 1; j <= 5; j++) {
String text = "";
switch (j) {
case 1:
text = TimeHelper.convertTime(event.getDate().getTime());
break;
case 2:
text = event.getType();
break;
case 3:
text = (event.getDetails().get("Value") != null) ? event
.getDetails().get("Value") : "";
break;
case 4:
text = (event.getDetails().get("Unit") != null) ? event
.getDetails().get("Unit") : "";
break;
case 5:
text = (event.getDetails().get("comment") != null) ? event
.getDetails().get("comment") : "";
break;
}
TextView txtField = new TextView(ParentActivity);
txtField.setText(text);
txtField.setBackgroundColor(Color.GRAY);
txtField.setGravity(Gravity.CENTER);
tr.addView(txtField);
txtField.setLayoutParams(lp);
}
timelineTable.addView(tr);
}
}
