为什么下面的android代码不显示

// 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);

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