RelativeLayout onClick onTouch無法正常工作

Question

我無法爲RelativeLayout附加onTouch/onClick事件。我在網上搜索了很多，可以找到使用dispatchTouchEvent(MotionEvent)的可能解決方案。但我不想用這種方式，因爲我在實施時也遇到了一些麻煩。代碼如下。

public class ConnectMeDigit extends RelativeLayout implements AddressAware { 



    public ConnectMeDigit(Context context, AttributeSet attrs) { 
     super(context, attrs); 
     View view = LayoutInflater.from(context).inflate(R.layout.numpad_digit, this); 

     Typeface face=Typeface.createFromAsset(context.getAssets(), "helveticathin.ttf");//"helveticaultralight.ttf"); 

     String xmlProvidedSize = attrs.getAttributeValue("http://schemas.android.com/apk/res/android", "tag"); 
     TextView keypadnumber = (TextView) view.findViewById(R.id.keypadnumber); 
     TextView keypadalphabets = (TextView) view.findViewById(R.id.keypadalphabets); 
     TextView keypadplussubscript = (TextView) view.findViewById(R.id.keypadplussubscript); 

     keypadnumber.setTypeface(face); 
     keypadalphabets.setTypeface(face); 
     keypadplussubscript.setTypeface(face); 

     keypadplussubscript.setVisibility(View.GONE); 

     keypadnumber.setText(xmlProvidedSize); 

     if(xmlProvidedSize.equals("1")) { 
      keypadalphabets.setVisibility(View.GONE); 
     }  
     else if(xmlProvidedSize.equals("2")) { 
      keypadalphabets.setText("ABC");  
     }  
     else if(xmlProvidedSize.equals("3")) { 
      keypadalphabets.setText("DEF");    
     }  
     else if(xmlProvidedSize.equals("4")) { 
      keypadalphabets.setText("GHI");    
     }  
     else if(xmlProvidedSize.equals("5")) { 
      keypadalphabets.setText("JKL");    
     }  
     else if(xmlProvidedSize.equals("6")) { 
      keypadalphabets.setText("MNO");    
     } 
     else if(xmlProvidedSize.equals("7")) { 
      keypadalphabets.setText("PQRS");     
     } 
     else if(xmlProvidedSize.equals("8")) { 
      keypadalphabets.setText("TUV");    
     } 
     else if(xmlProvidedSize.equals("9")) { 
      keypadalphabets.setText("WXYZ");     
     } 
     else if(xmlProvidedSize.equals("0")) { 
      keypadplussubscript.setVisibility(View.VISIBLE); 
      keypadalphabets.setVisibility(View.GONE);   
     } 
     else if(xmlProvidedSize.equals("*")) { 
      keypadalphabets.setVisibility(View.GONE); 
     } 
     else if(xmlProvidedSize.equals("#")) { 
      keypadalphabets.setVisibility(View.GONE); 
     } 

     System.out.println("ConnectMeDigit.this.getTag(): " + ConnectMeDigit.this.getTag()); 
     System.out.println("xmlProvidedSize: " + xmlProvidedSize); 
     setEnabled(true); 
     setFocusable(true); 
     setFocusableInTouchMode(true);//setFocusable(true); 
     setClickable(true); 
     setLongClickable(true); 


     DialKeyListener lListener = new DialKeyListener(xmlProvidedSize); 


     setOnClickListener(lListener); 
     setOnTouchListener(lListener); 

     if (xmlProvidedSize.equals("0")) {//("0+".equals(text)) { 
      setOnLongClickListener(lListener); 
     } 


    } 


    private AddressText mAddress; 
    public void setAddressWidget(AddressText address) { 
     mAddress = address; 
    } 

    private boolean mPlayDtmf; 
    public void setPlayDtmf(boolean play) { 
     mPlayDtmf = play; 
    }  


    private class DialKeyListener implements OnClickListener, OnTouchListener, OnLongClickListener { 
     final char mKeyCode; 
     boolean mIsDtmfStarted; 

     /*DialKeyListener() { 
      mKeyCode = ConnectMeDigit.this.getText().subSequence(0, 1).charAt(0); 
     }*/ 
     DialKeyListener(String character) { 
      mKeyCode = character.charAt(0); //ConnectMeDigit.this.getText().subSequence(0, 1).charAt(0); 
      System.out.println("mKeyCode: " + mKeyCode); 
     } 

     private boolean linphoneServiceReady() { 
      if (!LinphoneService.isReady()) { 
       Log.w("Service is not ready while pressing digit"); 
       Toast.makeText(getContext(), getContext().getString(R.string.skipable_error_service_not_ready), Toast.LENGTH_SHORT).show(); 
       return false; 
      } 
      return true; 
     } 

     public void onClick(View v) { 
      if (mPlayDtmf) { 
       if (!linphoneServiceReady()) return; 
       LinphoneCore lc = LinphoneManager.getLc(); 
       lc.stopDtmf(); 
       mIsDtmfStarted =false; 
       if (lc.isIncall()) { 
        lc.sendDtmf(mKeyCode); 
       } 
      } 

      if (mAddress != null) { 
       int lBegin = mAddress.getSelectionStart(); 
       if (lBegin == -1) { 
        lBegin = mAddress.length(); 
       } 
       if (lBegin >= 0) { 
        mAddress.getEditableText().insert(lBegin,String.valueOf(mKeyCode)); 
       } 
      } 
     } 

     public boolean onTouch(View v, MotionEvent event) { 
      if (!mPlayDtmf) return false; 
      if (!linphoneServiceReady()) return true; 

      if (InCallActivity.isInstanciated()) { 
       InCallActivity.instance().resetControlsHidingCallBack(); 
      } 

      LinphoneCore lc = LinphoneManager.getLc(); 
      if (event.getAction() == MotionEvent.ACTION_DOWN && !mIsDtmfStarted) { 
       LinphoneManager.getInstance().playDtmf(getContext().getContentResolver(), mKeyCode); 
       mIsDtmfStarted = true; 
      } else { 
       if (event.getAction() == MotionEvent.ACTION_UP) { 
        lc.stopDtmf(); 
        mIsDtmfStarted = false; 
       } 
      } 
      return false; 
     } 

     public boolean onLongClick(View v) { 
      if (mPlayDtmf) { 
       if (!linphoneServiceReady()) return true; 
       // Called if "0+" dtmf 
       LinphoneCore lc = LinphoneManager.getLc(); 
       lc.stopDtmf(); 
      } 

      if (mAddress == null) return true; 

      int lBegin = mAddress.getSelectionStart(); 
      if (lBegin == -1) { 
       lBegin = mAddress.getEditableText().length(); 
      } 
      if (lBegin >= 0) { 
      mAddress.getEditableText().insert(lBegin,"+"); 
      } 
      return true; 
     } 
    }; 


} 

我試過setEnabled(true) setFocusable(true) setFocusableInTouchMode(true) setClickable(true) setLongClickable(true)，它們都不起作用。

嘗試使用

view.setOnClickListener(lListener); 
view.setOnTouchListener(lListener); 

代替

setOnClickListener(lListener); 
setOnTouchListener(lListener);
