應用程序意外停止，錯誤顯示

-1

我正在處理文本到語音應用程序。我給了一個輸入字符串並通過按鈕進行轉換。當我點擊按鈕時，應用程序意外關閉。當輸入被硬編碼時，應用程序正常運行。應用程序意外停止，錯誤顯示

EditText text; 
String[] texts ; 
TextToSpeech tts; 
@Override 
public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.main); 
    texts = new String[3]; 
    text = (EditText)findViewById(R.id.ttexttovoice); 
    //Editable debug = text.getText(); 
    texts[0] = text.getText().toString(); 
    Button b = (Button)findViewById(R.id.btexttovoice); 
    b.setOnClickListener(this); 
    tts = new TextToSpeech(textvoice.this,new TextToSpeech.OnInitListener(){ 

     @Override 
     public void onInit(int status) { 
      // TODO Auto-generated method stub 
      if(status!= TextToSpeech.ERROR) 
      { 
       tts.setLanguage(Locale.US); 

      } 
      } 
    }); 

} 

@Override 
protected void onPause() { 
    // TODO Auto-generated method stub 
    if(tts!= null) 
    { 
     tts.stop(); 
     tts.shutdown(); 
    } 
    super.onPause(); 
} 

@Override 
public void onClick(View v) { 
    // TODO Auto-generated method stub 
    Random r = new Random(); 
    String rn = texts[r.nextInt(3)]; 
    tts.speak(rn, TextToSpeech.QUEUE_FLUSH, null); 
}

} 這裏是logcat的：

你的方法中是否有任何'log'代碼行？ – iTurki 2012-07-29 01:31:46

你給'文本'中的第一項是一個值，但不是其他值？如果蘭特選擇1或2，你會發生什麼？ – 2012-07-29 01:31:57

我認爲文本[r.nextInt（3）]是null.pls保證文本[0]〜文本[2]具有值的字符串。

這是整個代碼。沒有提到日誌代碼行。好的，如果文本[r.nextInt（3）]爲空我應該用什麼來代替文本[0]來將數組字符串作爲輸入。 – dan 2012-07-29 08:44:26
