有没有办法获得我的编辑文本的价值？帮助我请提前谢谢你..

TableLayout table = new TableLayout(getApplicationContext());
    table.setVerticalScrollBarEnabled(true);
    table.setPadding(10, 10, 10, 10);

    TableRow tableRow = new TableRow(getApplicationContext());
    TextView txt = new TextView(getApplicationContext());
    tableRow.addView(txt);
    tableRow.setBackgroundColor(Color.GRAY);
    txt.setText("Excellent  ");
    table.addView(tableRow);

    int j = 0;
    for (j = 1; j <= count; j++) {

在方法之外创建出色的参考。

TableLayout table = new TableLayout(getApplicationContext());
        table.setVerticalScrollBarEnabled(true);
        table.setPadding(10, 10, 10, 10);

EditText excellent;

    TableRow tableRow = new TableRow (getApplicationContext());             
    TextView txt = new TextView (getApplicationContext());
    tableRow.addView(txt);
    tableRow.setBackgroundColor(Color.GRAY);
    txt.setText("Excellent  ");
    table.addView(tableRow);

int j=0;
        for(j = 1; j<=count; j++){


            TableRow tableRow2 = new TableRow (getApplicationContext());                



            excelent = new EditText (getApplicationContext());
                  tableRow2.addView(excellent);
   }



        TableRow tableRow1 = new TableRow (getApplicationContext());

        Button showtable = new Button(getApplicationContext());
        tableRow1.addView(showtable);
        showtable.setText("Show Table");
        showtable.setTextSize(8);


        showtable.setOnClickListener(new OnClickListener(){

            @Override
            public void onClick(View arg0) {
                // TODO Auto-generated method stub
                   excellent.getText().toString();//i cant get the value of excellent.
          }

        });
