爲什麼下面的android代碼不顯示

// customize linear layout  
    LinearLayout mainLayout = new LinearLayout(this); 
    LinearLayout originWordsLayout = new LinearLayout(this); 
    LinearLayout transWordsLayout = new LinearLayout(this); 
    mainLayout.setOrientation(LinearLayout.HORIZONTAL); 
    originWordsLayout.setOrientation(LinearLayout.VERTICAL); 
    transWordsLayout.setOrientation(LinearLayout.VERTICAL); 

    // set col 1 
    TextView originTitle = new TextView(this); 
    originTitle.setWidth(android.view.ViewGroup.LayoutParams.MATCH_PARENT); 
    originTitle.setHeight(android.view.ViewGroup.LayoutParams.MATCH_PARENT); 
    originTitle.setText("col1"); 
    originWordsLayout.addView(originTitle); 


    // set col 2 
    TextView transTitle = new TextView(this); 
    transTitle.setWidth(android.view.ViewGroup.LayoutParams.MATCH_PARENT); 
    transTitle.setHeight(android.view.ViewGroup.LayoutParams.MATCH_PARENT); 
    transTitle.setText("col2"); 
    transWordsLayout.addView(transTitle); 



    mainLayout.addView(originWordsLayout); 
    mainLayout.addView(transWordsLayout); 
    setContentView(mainLayout);

當我運行我的應用程序時，屏幕上沒有任何東西任何人都告訴我我的代碼有什麼問題？什麼我想要做的就是動態地添加一些瀏覽到我的佈局爲什麼下面的android代碼不顯示

originWordsLayout和transWordsLayout應該WRAP_CONTENT等等TextView transTitle和TextView originTitle代替MATCH_PARENT
