【问题描述】：
我在查看我试图填充 TableLayout 的数据时遇到问题。当我运行代码时，它不会出错，但表格没有填充数据，它只是显示为空白并且我所能看到的只是我在xml file 中定义的标题行。
我查看了多个示例，并弄乱了那里给出的一些答案，比如在我的行中切换参数（我还没有找到正确的组合），并且我已经更改了从中导入的内容view 到 widget 仍然没有...
public void createTable(String xmlForTable)
throws XmlPullParserException, IOException {
//public void createTable(){
Integer i = 0;
endPlacementTag = "nothing";
//setContentView(R.layout.activity_all_tires);
lo = (TableLayout) findViewById(R.id.tiresTable);
TableRow headerRow = new TableRow(this);
TableRow.LayoutParams hp = new TableRow.LayoutParams(TableRow.LayoutParams.WRAP_CONTENT, TableRow.LayoutParams.WRAP_CONTENT);
headerRow.setLayoutParams(hp);
tv = new TextView(this);
tv.setText("Text Header");
headerRow.addView(tv);
lo.addView(headerRow);
XmlPullParserFactory factory = XmlPullParserFactory.newInstance();
factory.setNamespaceAware(true);
XmlPullParser xpp = factory.newPullParser();
xpp.setInput(new StringReader (xmlForTable));
int eventType = xpp.getEventType();
TableRow row= new TableRow(this);
TableRow.LayoutParams lp = new TableRow.LayoutParams(TableRow.LayoutParams.WRAP_CONTENT,TableRow.LayoutParams.WRAP_CONTENT);
row.setLayoutParams(lp);
rfid = new TextView(this);
projectNumber = new TextView(this);
inspectionLotNumber = new TextView(this);
serialization = new TextView(this);
spec = new TextView(this);
sku = new TextView(this);
materialNumber = new TextView(this);
while (eventType != XmlPullParser.END_DOCUMENT) {
if(eventType == XmlPullParser.START_DOCUMENT) {
System.out.println("Start document");
} else if(eventType == XmlPullParser.END_DOCUMENT) {
System.out.println("End document");
} else if(eventType == XmlPullParser.START_TAG) {
System.out.println("Start tag "+xpp.getName());
placementTag = xpp.getName();
} else if(eventType == XmlPullParser.END_TAG) {
System.out.println("End tag "+xpp.getName());
endPlacementTag = "End tag "+xpp.getName();
} else if(eventType == XmlPullParser.TEXT) {
System.out.println("Text "+xpp.getText());
}
....//filled with more if statements same as this one just different .equals
if(placementTag.equals("MaterialNumber"))
{
materialNumber.setText(xpp.getText());
materialNumber.setTextSize(10);
materialNumber.setLayoutParams(new LayoutParams (LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT));
//row.addView(materialNumber);
placementTag = "";
}
else if(endPlacementTag.equals("End tag Table"))
{
row.addView(rfid);
row.addView(projectNumber);
row.addView(inspectionLotNumber);
row.addView(serialization);
row.addView(spec);
row.addView(sku);
row.addView(materialNumber);
row.setGravity(Gravity.CENTER);
row.setLayoutParams(new TableLayout.LayoutParams(LayoutParams.WRAP_CONTENT,LayoutParams.WRAP_CONTENT));
lo.addView(row, new TableLayout.LayoutParams(LayoutParams.WRAP_CONTENT,LayoutParams.WRAP_CONTENT));
i++;
row.removeAllViews();
lo.removeAllViews();
}
}
eventType = xpp.next();
}
这是我的 XML：
<TableLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#C0C0C0" >
<!-- Once the column headers are known go back into the string.xml file and add them to elimiate warnings -->
<TableRow android:background="#C0C0C0"
>
<TextView
android:layout_width="200dp"
android:layout_column="0"
android:layout_weight="1"
android:text="NUM" />
<TextView

<TextView

android:layout_column="6"
android:layout_weight="1"
android:text="Material Number" />
</TableRow>
<ScrollView android:layout_height="match_parent"
android:scrollbars="horizontal|vertical"
android:layout_width="match_parent"
>
<HorizontalScrollView
android:layout_height="wrap_content"
android:scrollbars="horizontal|vertical"
android:layout_width="wrap_content" >
<TableLayout android:id="@+id/tiresTable"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#C0C0C0" >
<TableRow>
</TableRow>
</TableLayout>
</HorizontalScrollView>
</ScrollView>
</TableLayout>
