如何更改切換按鈕使用void開始（）

Question

這是我的代碼，我想運行它沒有按鈕

請幫助我;

我在Android的興趣，這是我對學校的期末項目

感謝出席

Answer 1

你想要做一些代碼，當用戶點擊任何地方。

好吧......我想我終於明白你在說什麼了。每當用戶點擊隨時隨地時間，這種方法將被調用：

@Override 
    public void onUserInteraction() { 
     super.onUserInteraction(); 
}  

你的情況

所以，代碼應該是：

 @Override 
     public void onUserInteraction() { 
      super.onUserInteraction(); 
if (onOffButton.isChecked()) { 
      readPreferences(); 
      micInput.setSampleRate(mSampleRate); 
      micInput.setAudioSource(mAudioSource); 
      micInput.start(); 
     } else { 
      micInput.stop(); 
     }

編輯：

從文檔：

我不確定何時需要執行代碼，但看看圖表並找到合適的位置。這裏有一個例子：

@Override 
     public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
    if (onOffButton.isChecked()) { 
        readPreferences(); 
        micInput.setSampleRate(mSampleRate); 
        micInput.setAudioSource(mAudioSource); 
        micInput.start(); 
       } else { 
        micInput.stop(); 
    }

像這樣

@Override 
    public void onResume() { 
      super.onResume(); 

      Inisialisasi(); 
      mDisplay.setLevel(0, mThreshold); 

      if (!mRunning) { 
       mRunning = true; 
       start(); 
      } 
    } 

    @Override 
    public void onStop() { 
      super.onStop(); 
      stop(); 

    } 

    private void start() { 

      mSensor.start(); 
      if (!mWakeLock.isHeld()) { 
        mWakeLock.acquire(); 
      } 

      mHandler.postDelayed(mPollTask, POLL_INTERVAL); 
    }
