我有一定的问题。我正在使用自定义tableLayout创建一个可消耗的List作为consumeableList的子项。表格输出每行有1个textView和3个EditText。
现在，问题是TableLayout中的editTexts没有检测到在运行时输入的文本。它从editText中提供空白值。请查找附带的代码并建议我克服这个问题的建议。
主要问题在于gettabledata（）中的editText方法显示isInEditMode“False”。你能帮忙我们如何在运行时将IsInEditMode设置为“true”。

在每个EditText上设置一个TextWatcher，当editText中的文本被更改时将调用它。
答案 1 :(得分：0)
实际上，问题通过在getChildView（）中的每个EditText上设置TextWatcher而不是getTableData（）方法来解决，同时初始化EditText.Fetch数据并且每次在任何其他变量中存储在edittext中输入的数据。因为getChildView（）在单击每个editText时会重新加载。因此，editText值也需要存储在任何其他变量中，以便检索后面的数据。
示例：
@Override public void beforeTextChanged（CharSequence s，int start，int count，int after）{// TODO自动生成的方法存根 }
public void afterTextChanged(Editable s) { // TODO
if((s!=null&&s.length()>0)){
v2 = s.toString();
Pattern p = Pattern.compile( "([0-9]*)" );
Matcher m = p.matcher(v2);
System.out.println("v2 :::::" + v2);
if(stateCount>=States.length)
stateCount =0;
else
stateCount = stateCount+1;
System.out.println("SateCount in v2:::::::::::::::" + stateCount);
insertInV2Array(stateCount,v2);
if(!m.matches())
{
Toast.makeText(VarietyDetailsActivity.this, "Please enter between 1- 9 only",8 )
.show();
}
}
