我正在使用語音識別器使用語音到文本的概念，但是當文本設定為編輯文本時，編輯文本中的現有文本將被洗掉，并將從語音轉換的文本設定在其位置。
但是，我希望在現有文本之后設定轉換后的文本，而不替換現有文本。

uj5u.com熱心網友回復：
@Override
public void onResults(Bundle results) {
micButton.setImageResource(R.drawable.ic_baseline_mic_off_24);
ArrayList<String> data = results.getStringArrayList(SpeechRecognizer.RESULTS_RECOGNITION);
editTextDescription.setSelection(editTextDescription.getText().length());
editTextDescription.setText(data.get(0));
}
您告訴它突出顯示整個文本，然后設定文本。這將擺脫任何選擇（這也是多余的，因為如果您沒有設定選擇，也會發生同樣的事情）。如果要繼續，請使用
editTextDescription.setText(editTextDescription.getText().toString() data.get(0))
那應該替換該函式的最后兩行。它將獲取現有文本，將新結果附加到它，并將總字串設定為視圖。
