当我试图获取值来计算总数时，我无法获取值，而是获取android.widget.TableRow@4103c468。我怎样才能克服这种情况，我需要将这些值传递给另一个Activity。我的代码：
public class ProvisionActivity extends Activity {
private TableLayout mTable;
private static int sCount = 0;
Button btnAdd;
String[] pnames = { "provision1", "provision2", "provision3", "provision4",
"provision5" };
String[] pprice = { "45", "85", "125", "15", "198" };
StringBuffer xpenses;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
btnAdd = (Button) findViewById(R.id.button1);
mTable = (TableLayout) findViewById(R.id.tableprovision);
xpenses = new StringBuffer();
btnAdd.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
mTable.addView(addRow(pnames, pprice));
for (int i = 0; i < mTable.getChildCount(); i++) {
mTable.getChildAt(i);
System.out.println("Table Row values are "
+ mTable.getChildAt(i));
xpenses = xpenses.append(mTable.getChildAt(i).toString());
System.out
.println("Expense Table Values Are After Storing it in a String variable "
+ xpenses);
}
}
});
}
private TableRow addRow(String[] sname, final String[] sprice) {
TableRow tr = new TableRow(this);
tr.setId(1000 + sCount);
tr.setLayoutParams(new TableLayout.LayoutParams(
TableLayout.LayoutParams.FILL_PARENT,
TableLayout.LayoutParams.WRAP_CONTENT));
TableRow.LayoutParams blparams = new TableRow.LayoutParams(150, 35);
final Spinner spinner = new Spinner(this);
spinner.setLayoutParams(blparams);
spinner.setBackgroundColor(Color.DKGRAY);
ArrayAdapter<String> xtypeadapter = new ArrayAdapter<String>(this,
android.R.layout.simple_spinner_dropdown_item, sname);
spinner.setAdapter(xtypeadapter);
tr.addView(spinner);
TableRow.LayoutParams tlparams = new TableRow.LayoutParams(55,
TableLayout.LayoutParams.WRAP_CONTENT);
final TextView textView = new TextView(this);
textView.setLayoutParams(tlparams);
textView.setTextColor(Color.BLACK);
spinner.setOnItemSelectedListener(new OnItemSelectedListener() {
public void onItemSelected(AdapterView<?> arg0, View arg1,
int arg2, long arg3) {
textView.setText(" "
+ sprice[spinner.getSelectedItemPosition()]);
}
public void onNothingSelected(AdapterView<?> arg0) {
}
});
tr.addView(textView);
TableRow.LayoutParams blparams1 = new TableRow.LayoutParams(
TableRow.LayoutParams.WRAP_CONTENT,
TableRow.LayoutParams.WRAP_CONTENT);
final Button button = new Button(this);
button.setLayoutParams(blparams1);
button.setBackgroundColor(Color.LTGRAY);
button.setText(" - ");
button.setId(2000 + sCount);
button.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
mTable.removeView(findViewById(v.getId() - 1000));
}
});
tr.addView(button);
sCount++;
return tr;
}
}
