这是动态创建功能可点击TableRows [英] Functional Clickable TableRows that are created dynamically
问题描述
我看到这个链接（http://stackoverflow.com/questions/6603868/android-onclicklistener-and-table-layout）这似乎是它为问这个问题的人。话虽这么说，这里是我的情况。
I saw this link (http://stackoverflow.com/questions/6603868/android-onclicklistener-and-table-layout) which seems like it works for the person asking the question. That being said, here's my situation.
我有一个TableLayout，动态填充数据的四列。该行作为一个整体需要可以点击的，因为有像上面链接的例子没有任何按键。
I have a TableLayout, dynamically filled with four columns of data. The row as a whole needs to be clickable, since there are no buttons like the example linked above.
一个点击行需要通过它的第一列的（列0）的数据，这仅仅是一个字符串。这里是被称为创造一个新行的功能。
A clicked row needs to pass its first column's(column 0) data, which is just a string. Here is the function that's called to create a new row.
private void addLotTableRow(CharSequence [] row, int count) {
final TableLayout table = (TableLayout) findViewById(R.id.lotsTableList);
final TableRow tr = (TableRow) getLayoutInflater().inflate(R.layout.lotsrow, null);
TextView tv;
// Fill Cells
tv = (TextView) tr.findViewById(R.id.lotCell1);//Cell 1: Lot Number
tv.setText(row[0]);
tv = (TextView) tr.findViewById(R.id.lotCell2);//Cell 2: Sample
tv.setText(row[1]);
tv = (TextView) tr.findViewById(R.id.lotCell3);//Cell 3: Inspected
tv.setText(row[3]);
tv = (TextView) tr.findViewById(R.id.lotCell4);//Cell 4: Total
tv.setText(row[2]);
table.addView(tr);
}
所以，我本来试图使tr.setOnClickListener（新View.OnclickListener（）{blahblah}）;在这个函数中，对前table.addView（TR）线。该等等等等当然是一个onClick（视图V）函数。我原本只能取得最后一行的数据，无论我点击哪一行。现在，我试图做类似上面的链接，并从上涨的功能产生onclicks，所有的表行已被创建之后。我大概可以给更多的信息，但我认为人们可以从这个的想法现在！感谢您的帮助！
So I originally tried to make a tr.setOnClickListener(new View.OnclickListener() {blahblah}); in this function, right before the table.addView(tr) line. The "blah blah" was of course an onClick(View v) function. I originally would only get the last row's data, no matter which row I clicked. Now, I'm trying to do like the link above, and produce the onclicks from a higher up function, after all the table rows have been created. I probably can give more info, but I think people can get the idea for now from this! Thanks for any help!
推荐答案
底线：我想它了。
这是我张贴在问题的链接立足我的解决方案，我意识到我需要做出一个TextView对象，以看到一个单元格的数据！因此，这里是我的code，在连接到code上面一直没有改变！
Basing my solution from the link I posted in the question, I realized that I needed to make a textview object in order to see a cell's data! So here is my code, in connection to the code above that has remained unchanged!
int rowNumCount = table.getChildCount();
for(int count = 1; count < rowNumCount; count++) {
View v = table.getChildAt(count);
if(v instanceof TableRow) {
final TableRow clickRow = (TableRow)v;
int rowCount = clickRow.getChildCount();
v.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
Context context = getTabHost().getContext();
TableRow row = (TableRow)v;
TextView tv = (TextView)row.getChildAt(0);
CharSequence text = "Lot VALUE Selected: " + tv.getText();
int duration = Toast.LENGTH_SHORT;
Toast.makeText(context, text, duration).show();
}
});
}
}
就像我说的，我只需要抢到第一列中的数据，从而row.getChildAt（0）;线！所以我知道没有人甚至可能不得不回答这个问题还没有机会，但我希望我的回答可以帮助别人的未来！
Like I said, I only needed to grab the first columns data, thus the row.getChildAt(0); line! So I know nobody probably even had the chance to answer this question yet, but I hope my answer can help others in the future!
理的问题，为什么不直接使用一个ListView？
答：我觉得我在做什么，以表格的形式看起来好多了。
Rationale to the question, "Why not just use a listview?" Answer: I think for what I'm making, a tabular format looks much better.
虽然我可能不会让我的code的设置一个巨大的变化，我总是开听到的变化，可以帮助改善我的code！我爱这个社会！
While I may not make a huge change to my code's setup, I am ALWAYS open to hear changes that could help improve my code! I love this community!
