我的代码遵守http://android-er.blogspot.com/2009/10/multi-language-translate.html

并强行关闭

private void showLang() {
    db.open();
    cursor = db.getLang();
    cursor.moveToFirst();
    startManagingCursor(cursor);
    SimpleCursorAdapter qc = new SimpleCursorAdapter(
            this,
            android.R.layout.simple_spinner_item,
            cursor,
            new String[] {DBAdapter.KEY_LANG},
            new int[] {android.R.id.text1});
        qc.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
        Language_Spinner.setAdapter(qc);

        TranslateButton.setOnClickListener(new OnClickListener() {

            public void onClick(View arg0) {
                String InputString;
                String OutputString = null;
                InputString = Thai_word.getText().toString();

                String language = (String)Language_Spinner
                .getItemAtPosition((int) Language_Spinner.getSelectedItemId());

                try {
                    Translate.setHttpReferrer("http://android-er.blogspot.com/");
                    OutputString = Translate.execute(InputString,
                            Language.ENGLISH,Language.THAI);

                } catch (Exception ex) {
                    ex.printStackTrace();
                    OutputString = "Error";
              }
                Target_word.setText(OutputString+language);
            }       
        });

}

}

这是我的logcat

String language = (String)Language_Spinner
                .getItemAtPosition((int) Language_Spinner.getSelectedItemId());

我认为你的问题就在这里。此方法不返回字符串,因此会发生类强制转换异常。
