滾動視圖內部的水平和垂直線性佈局

Question

所以我試圖獲得視圖的組合建立。他們必須不斷地有按鈕和EDITTEXT箱體頂部水平彼此相鄰並低於的一個垂直列表Textviews。垂直列表應包含在一個滾動型允許用戶向下穿過TextViews滾動（該按鈕和的EditText頂部應仍是可見的，而這種情況正在發生）。

protected void initLayout() { 
    // Declaring the vertical layout 
    verticalLayout=new LinearLayout(this); 
    verticalLayout.setOrientation(LinearLayout.VERTICAL); 
      //Declaring the horizontal layout 
    horizontalLayout=new LinearLayout(this); 
    horizontalLayout.setOrientation(LinearLayout.HORIZONTAL); 
      //set the main view as horizontal at the top 
    setContentView(horizontalLayout); 
      //Declaring the scroll view 
    ScrollView scrollView= new ScrollView(this); 
    scrollView.addView(verticalLayout); 
      //set the scroll view 
    setContentView(scrollView); 
    //declare and add button to horizontal view 
    theButton= new Button(this); 
    theButton.setText("Add Joke"); 
    horizontalLayout.addView(theButton); 
    //declare and add edittext to horizontal view 
    theEditText= new EditText(this); 
    theEditText.setLayoutParams(new LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT,LinearLayout.LayoutParams.MATCH_PARENT)); 
    horizontalLayout.addView(theEditText); 
} 

我相信我可能會出錯setContentView，但不完全確定。如果有人有任何意見，將不勝感激

我找到了解決問題的辦法。我不得不在另一個線性佈局中封裝水平佈局和垂直佈局，並將其設置爲根視圖。

protected void initLayout() { 
    // Declaring the vertical layout 
    verticalLayout=new LinearLayout(this); 
    verticalLayout.setOrientation(LinearLayout.VERTICAL); 

    //Declaring the horizontal layout 
    horizontalLayout=new LinearLayout(this); 
    horizontalLayout.setOrientation(LinearLayout.HORIZONTAL); 

    //***SOLUTION*** Create a view to group the other views in 
    groupLayout=new LinearLayout(this); 
    groupLayout.setOrientation(LinearLayout.VERTICAL);//vertical as the horizontal view is on top of the vertical view 

    //Declaring the scroll view 
    ScrollView scrollView= new ScrollView(this); 
    scrollView.addView(verticalLayout);//the vertical layout is the only view that should be scrollable and therefore added to the scrollview 

    //declare and add button to horizontal view 
    theButton= new Button(this); 
    theButton.setText("Add Joke"); 
    horizontalLayout.addView(theButton); 
    //declare and add edittext to horizontal view 
    theEditText= new EditText(this); 
    theEditText.setLayoutParams(new LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT,LinearLayout.LayoutParams.MATCH_PARENT)); 
    horizontalLayout.addView(theEditText); 

    //***SOLUTION*** attach the views to the group view 
    groupLayout.addView(horizontalLayout); //the layout displayed at the top of the group layout 
    groupLayout.addView(scrollView); //the layout below the top (scrollview already contains the vertical view) 

    setContentView(groupLayout);//assign the group layout to the content 
}

你的父母ViewGroup必須是一個。你正在使用2次setContentView，這是你的錯誤。只使用一個，並在另一箇中添加其他線性佈局作爲子項。 我認爲你最好在xml中嘗試做，然後編寫你的代碼。

Answer 3

基本上你已經得到了錯誤的setContentView ...
我強烈建議在XML來定義佈局 - 然後用下面的設置它只是一次：

setContentView(R.layout.my_xml_layout); 

這種方式 - 通常你確實有可能看到你的佈局，並且它是（在我看來）easyer來定義一個佈局（特別是如果你決定改變這一天）。

，如果你wan't做代碼然而，你必須做的就是像下面這樣（未經測試 - 但應該工作）

protected void initLayout() { 
// Declaring the vertical layout 
verticalLayout=new LinearLayout(this); 
verticalLayout.setOrientation(LinearLayout.VERTICAL); 

//Declaring the horizontal layout 
horizontalLayout=new LinearLayout(this); 
horizontalLayout.setOrientation(LinearLayout.HORIZONTAL); 
verticalLayout.addView(horizontalLayout); //add the Horizontal-View to the parent-grid 

//Declaring the scroll view 
ScrollView scrollView= new ScrollView(this); 
scrollView.addView(verticalLayout); 
//set the scroll view 
verticalLayout.addView(scrollView); //add the scrollview to the parent-grid 
//declare and add button to horizontal view 
theButton= new Button(this); 
theButton.setText("Add Joke"); 
horizontalLayout.addView(theButton); 
//declare and add edittext to horizontal view 
theEditText= new EditText(this); 
theEditText.setLayoutParams(new LayoutParams(LinearLayout.LayoutParams.MATCH_PARENT,LinearLayout.LayoutParams.MATCH_PARENT)); 
horizontalLayout.addView(theEditText); 
setContentView(verticalLayout); 
} 

編輯：對不起 - 有幾個錯誤第一次 - 我現在編輯它，它應該像這樣工作。
