【问题描述】：
对不起我的英语！ 我对 BigDecimal 有疑问。 我创建了一个 SQLiteDatabase。现在我想用搜索视图搜索。
private void showResults(String query) {
Cursor cursor = mDbHelper.searchCustomer((query != null ? query.toString() : "@@@@.@@"));
if (cursor == null) {
//
} else {
// Specify the columns we want to display in the result
String[] from = new String[] {
ItemDbAdapter.KEY_1,
ItemDbAdapter.KEY_2,
ItemDbAdapter.KEY_3,
ItemDbAdapter.KEY_4,
ItemDbAdapter.KEY_5,
ItemDbAdapter.KEY_6,
ItemDbAdapter.KEY_7,
ItemDbAdapter.KEY_8};
// Specify the Corresponding layout elements where we want the
// columns to go
int[] to = new int[] {
R.id.result_1,
R.id.result_2,
R.id.result_3,
R.id.result_4,
R.id.result_5,
R.id.result_6,
R.id.result_7,
R.id.result_8};
SimpleCursorAdapter customers = new SimpleCursorAdapter(this,
R.layout.customresult, cursor, from, to);
mListView.setAdapter(customers);
mListView.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
np.setValue(100); //Numberpicker
Cursor cursor = (Cursor) mListView.getItemAtPosition(position);
String 1 = cursor.getString(cursor.getColumnIndexOrThrow("1"));
String 2 = cursor.getString(cursor.getColumnIndexOrThrow("2"));
String 3 = cursor.getString(cursor.getColumnIndexOrThrow("3"));
String 4 = cursor.getString(cursor.getColumnIndexOrThrow("4"));
String 5 = cursor.getString(cursor.getColumnIndexOrThrow("5"));
String 6 = cursor.getString(cursor.getColumnIndexOrThrow("6"));
String 7 = cursor.getString(cursor.getColumnIndexOrThrow("7"));
String 8 = cursor.getString(cursor.getColumnIndexOrThrow("8"));
RelativeLayout customerLayout = (RelativeLayout) findViewById(R.id.custominfoLayout);
if (customerLayout == null) {
// Inflate the Customer Information View
RelativeLayout leftLayout = (RelativeLayout) findViewById(R.id.rightLayout);
View customerInfo = getLayoutInflater().inflate(
R.layout.custominfo, leftLayout, false);
leftLayout.addView(customerInfo);
}
Tv1 = (TextView) findViewById(R.id.info_i);
Tv2 = (TextView) findViewById(R.id.info_a);
Tv3 = (TextView) findViewById(R.id.info_k);
Tv4 = (TextView) findViewById(R.id.info_B);
Tv5 = (TextView) findViewById(R.id.info_k);
Tv6 = (TextView) findViewById(R.id.info_k2);
Tv7 = (TextView) findViewById(R.id.info_P);
Tv8 = (TextView) findViewById(R.id.info_F);
Tv1.setText(1);
Tv2.setText(2);
Tv3.setText(3);
Tv4.setText(4);
Tv5.setText(5);
Tv6.setText(6);
Tv7.setText(7);
Tv8.setText(8);
searchView.setQuery("", true);
直到这里它运作良好。我所寻求的已显示。
如果我想将值存储在 BigDecimal 中，我会收到以下错误消息：

我的过程是：
Sa = String.valueOf(Tv1.getText());
Sb = String.valueOf(Tv2.getText());
Sc = String.valueOf(Tv3.getText());
Sd = String.valueOf(Tv4.getText());
Se = String.valueOf(Tv5.getText());
Sf = String.valueOf(Tv6.getText());
Sg = String.valueOf(Tv7.getText());
Big1 = new BigDecimal(Sa);
Big2 = new BigDecimal(Sb);
Big3 = new BigDecimal(Sc);
Big4 = new BigDecimal(Sd);
Big5 = new BigDecimal(Se);
Big6 = new BigDecimal(Sf);
Big7 = new BigDecimal(Sg);
我不明白为什么会出现这个错误。
我只使用 String 和 BigDecimal，但错误是浮点数。

请显示您的完整堆栈跟踪。 （我还建议给你的变量起更有意义的名字，但那是另一回事。）
