函數如何知道哪個可點擊的textView使用onClick調用它？

Question

當我選擇通過onClick在可點擊的TextView上調用函數時，如何獲取函數以瞭解哪個TextView調用了它？

例如，當我有這個在我的MainActivity.java：

public void showHideData(View view) 
{ 
    //Log.v("showHideDataA: ", "Calling package null, local class name: " + this.getLocalClassName() + " request orientation: " + ("" + this.getRequestedOrientation())); 
    if (findViewById(R.id.letterContentTextViewArrayB).getVisibility() == View.VISIBLE) 
    { 
     findViewById(R.id.checkedB).setVisibility(View.GONE); 
     findViewById(R.id.notcheckedB).setVisibility(View.VISIBLE); 
     findViewById(R.id.letterContentTextViewArrayB).setVisibility(View.GONE); 
    } 
    else 
    { 
     findViewById(R.id.checkedB).setVisibility(View.VISIBLE); 
     findViewById(R.id.notcheckedB).setVisibility(View.GONE); 
     findViewById(R.id.letterContentTextViewArrayB).setVisibility(View.VISIBLE); 
    } 
} // end of showHideData(0) 

及以下TextViews：

  <TextView 
       android:id="@+id/firstLetterTextViewArrayA" 
       android:layout_width="wrap_content" 
       android:layout_height="wrap_content" 
       android:text="@string/btn_a_label" 
       android:clickable="true" 
       android:onClick="showHideData"/> 
      <TextView 
       android:id="@+id/firstLetterTextViewArrayB" 
       android:layout_width="wrap_content" 
       android:layout_height="wrap_content" 
       android:text="@string/btn_b_label" 
       android:clickable="true" 
       android:onClick="showHideData" /> 

有沒有辦法讓showHideData（查看視圖）知道哪些TextView調用它？

謝謝

public void showHideData(View view) 
{ 
    view.getId(); 
    ... 
} 

這將返回被點擊的view的ID。所以你可以使用switch聲明

public void showHideData(View view) 
{ 
    switch (view.getId()) { 
     case R.id.firstLetterTextViewArrayA: 
     // logic for this button 
     break; 
     case R.id.firstLetterTextViewArrayB: 
     // logic for this button 
     break; 
}
