字符串到BigDecimal

对不起我的英语！我对BigDecimal有问题。我已经创建了一个SQLiteDatabase。现在我想使用搜索视图进行搜索。

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);

在此之前，它运行良好。我所寻求的东西被展示出来了。

如果我想存储值​​在BigDecimal中，我收到以下错误消息：

我的流程为：

                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float。
