问题描述

当我试图获取值来计算总，我无法得到的值，而不是获取的 android.widget.TableRow@4103c468 的。我怎样才能克服这种情况多，我需要这些值传递给另一个活动。我的code：

    按钮btnAdd;

                            .println（费用表值是一个字符串变量保存完后
                                    + xpenses）;                }
            }
        }）;    }    私人的TableRow addRow（字符串[] SNAME，最终的String [] sprice）{        TR的TableRow =新的TableRow（本）;

}

When I'm trying to get the values to calculate the total I'm unable to get the values, instead getting android.widget.TableRow@4103c468. How can I overcome this situation and more I need to pass those values to another Activity. My code:

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) {

        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);

解决方案

i solved the above issue in the below shown way.. with some modifications to the above code

public class ProvisionActivity extends Activity {

private TableLayout mTable;
private static int sCount = 0;
Button btnAdd, btntot;
TextView tot;
int sum = 0;
String[] pnames = { "provision1", "provision2", "provision3", "provision4",
        "provision5" };
String[] pprice = { "45", "85", "125", "15", "195" };

@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);
    tot = (TextView) findViewById(R.id.textViewsum);
    btntot = (Button) findViewById(R.id.buttontotal);

    btnAdd.setOnClickListener(new OnClickListener() {

        public void onClick(View v) {
            mTable.addView(addRow(pnames, pprice));
        }
    });

    btntot.setOnClickListener(new OnClickListener() {

        public void onClick(View v) {

            int total = 0;
            for (int i = 0; i < mTable.getChildCount(); i++) {
                TableRow mRow = (TableRow) mTable.getChildAt(i);
                Spinner mspinner = (Spinner) mRow.getChildAt(0);
                TextView mTextView = (TextView) mRow.getChildAt(1);
                Log.i("mspinner", "" + mspinner.getSelectedItem());
                total = total
                        + Integer.parseInt(mTextView.getText().toString());
            }

            System.out.println("Sum of the provision are " + total);
            tot.setText("" + total);
        }

    });

}

private TableRow addRow(String[] sname, final String[] sprice) {

    TableRow tr = new TableRow(this);
    tr.setId(1000 + sCount);
    tr.setLayoutParams(new TableLayout.LayoutParams(
            TableLayout.LayoutParams.MATCH_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() {

        private boolean flag = false;

        public void onItemSelected(AdapterView<?> spin, View arg1,
                int position, long arg3) {
            if (flag) {
                flag = true;
                return;
            }

            textView.setText(sprice[position]);

        }

        public void onNothingSelected(AdapterView<?> arg0) {
            // TODO Auto-generated method stub

        }

    });
    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) {

            sCount--;
            mTable.removeView(findViewById(v.getId() - 1000));

        }
    });
    tr.addView(button);
    sCount++;
    return tr;

}
}
