how to get text of the neighbour textviews on some other textview's onclick event in dynamic table?_问答_开发者

i have textviews in table layout like this

----------------
|txt1|txt2|txt3|
----------------
|txt4|txt5|txt6|
----------------
|txt7|txt8|txt9|
----------------
|txt1|txt2|txt3|
----------------
|txt4|txt5|txt6|
----------------
|txt7|txt8|txt9|

and so on and on and on0

in this manner i am adding textviews again and again in for loop in the table layout acc to the data which is coming dynamically...

on txt7 click listener event i can get the text of the txt7 like this

((TextView)v).getText().toString();

now i need text of txt8 and txt9 text on txt7 click event

some body suggested me to do this by tagging textview

TextView uniqueTextView = (TextView)findViewById(R.id.unique_id);
TextView neighbourView = new TextView();
neighbourView.setTag(uniqueTe开发者_如何学JAVAxtView);

public void onTextViewClick(TextView view) {
TextView uniqueTextView = (TextView)view.getTag();
String text = uniqueTextView.getText().toString();   }

but this for one textview... how can i get text of both textview(txt8+txt9) on txt7 click listener.... plus i need text from txt7 also....

if it is not clear then you can comment....

this is dynamic table which i am creating

TableRow tr1 = (TableRow) new TableRow(this);
TextView txt1=new TextView(this);
TextView txt2=new TextView(this);
TextView txt3=new TextView(this);
txt1.setText("Data1);
txt2.setText("Data2);
txt3.setText("Data3);
txt1.setTag(1, txt2.getText().toString());
txt1.setTag(2, txt3.getText().toString());

txt1.setOnClickListener(new View.OnClickListener() 
{
     public void onClick(View v) 
     {
    try
    {
          Log.i("asdasd","Yahoo");
              Toast(((TextView)v).getTag(1).toString());
              Toast(((TextView)v).getTag(2).toString());
    }
    catch(Exception e)
    {
         Log.i("Error came while getting tag of txt1", e.getMessage());
        Toast("unable to bind tag");
        }
     }
});

tr1.addView(txt1);
tr1.addView(txt2);
tr1.addView(txt3);
TableLayout tl.addView(tr1,new TableLayout.LayoutParams(layoutParams));

as i cant set txt1 in place of ((TextView)v) because it will always give text of the last tablerow's txt1

why don't you try setTag (int key, Object tag) and getTag(int)

As in the example code you posted try this

txt7.setTag(1, txt8);
txt7.setTag(2, txt9);

public void onTextViewClick(TextView view) {
TextView txt8 = (TextView)view.getTag(1);
TextView txt9 = (TextView)view.getTag(2);   }

I have not used table layout yet. But you may can use like this

TableRow t =  (TableRow) v.getParent();
TextView t1 = (TextView) t.getChildAt(0);
TextView t2 = (TextView) t.getChildAt(1);
TextView t3 = (TextView) t.getChildAt(2);
