我一直致力于动态创建表布局，但在我的代码java.lang.AnumericeticException中出现了日志错误：除以零。密码我出错的地方无法从logcat中触发。
public void servershopimagesoffline() {
String Specifications = jsonarray;
try {
specifi = new JSONArray(Specifications);
} catch (JSONException e) {
e.printStackTrace();
}
if (specifi.length() > 0) {
for (int i = 0; i < specifi.length(); i++) {
try {
specification = specifi.getJSONObject(i);
} catch (JSONException e) {
e.printStackTrace();
}
TableLayout ll = (TableLayout) findViewById(R.id.maintable);
// header[i]=new TextView(getApplicationContext());
try {
String type = specification.getString("type");
if (type.equalsIgnoreCase("textfield")) {
String mainheader = specification.getString("main_header");

header = new TextView[fileopt.length()];

我还不清楚问题是什么，但我做了一些研究，注意到了以下几点：
TableLayout的开发人员文档提到"TableLayout子级不能指定layout_width属性。宽度始终为MATCH_PARENT"。您可以尝试根本不设置宽度，或者默认为MATCH_PARENT。
然后，在TableLayout的源代码中，在第583行周围，以计数为除数执行除法。可能发生的情况是，由于您将TableLayout的子级宽度设置为WRAP_CONTENT，它们没有正确添加，因此计数为0。
否则，我建议在TableLayout的onMeasure()中插入一个断点，看看情况是否确实如此，并尽量避免使用WRAP_CONTENT。
祝你好运，作为最后一句话，我还建议你尽量避免代码中出现这种数量的缩进。读起来很费劲！
我认为问题出在这里
row = new TableRow(this);
row.setLayoutParams(new TableRow.LayoutParams(
ViewGroup.LayoutParams.WRAP_CONTENT,
ViewGroup.LayoutParams.WRAP_CONTENT));
您应该将ViewGroup.LayoutParams更改为TableLayout.LayoutParams
最后我得到了问题的答案，因为dyanamic行必须创建Layout params
header[i].setLayoutParams(new TableRow.LayoutParams(TableRow.LayoutParams.FILL_PARENT, TableRow.LayoutParams.WRAP_CONTENT))
对于表格布局创建布局参数
ll.addView(row,newTableLayout.LayoutParams(TableLayout.LayoutParams.FILL_PARENT, TableLayout.LayoutParams.WRAP_CONTENT));`
"表格布局"小部件有一些规则，如果您将高度设置为wrap_content，则宽度必须与子布局的父布局匹配。
