下面是我的code:

  @覆盖  公共无效的onCreate(捆绑savedInstanceState){    super.onCreate(savedInstanceState);    上下文=这一点;    AlertDialog alertChoice =新AlertDialog.Builder(上下文).create();    alertChoice.setTitle(标题);    alertChoice.setView(ViewDialogScreen(测试));    alertChoice.show();  }  私人查看ViewDialogScreen(字符串strText的){    的LinearLayout llay =新的LinearLayout(背景);    llay.setLayoutParams(新的LayoutParams(320,400));    TextView的电视=新的TextView(背景);    tv.setText(strText的);    llay.addView(电视);    返回llay;  } 

我得到的输出象上面。

我需要在全屏显示 AlertDialog /屏幕尺寸的95%。 我需要在对话框来处理更多的领域。如何让 Horizo​​ntalScrollview AlertDialog 解决方案

要获得滚动行为,加上周围的滚动型来布局,这将使你的 ViewDialogScreen 方法如下:

 私人浏览ViewDialogScreen(字符串strText的){    滚动型滚动=新的滚动型(上下文);    scroll.setLayoutParams(新的LayoutParams(LayoutParams.FILL_PARENT,LayoutParams.FILL_PARENT));    的LinearLayout llay =新的LinearLayout(背景);    llay.setLayoutParams(新的LayoutParams(LayoutParams.FILL_PARENT,LayoutParams.FILL_PARENT));    TextView的电视=新的TextView(背景);    tv.setText(strText的);    scroll.addView(llay);    llay.addView(电视);    返回滚动;} 

现在尝试加入一些更多的领域,它应该滚动。

Here is my code:

@Override
  public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    context = this;    

    AlertDialog alertChoice = new AlertDialog.Builder(context).create();
    alertChoice.setTitle("Title");
    alertChoice.setView(ViewDialogScreen("Test"));    
    alertChoice.show();    
  }
  private View ViewDialogScreen(String strText) {
    LinearLayout llay = new LinearLayout(context);
    llay.setLayoutParams(new LayoutParams(320, 400));
    TextView tv = new TextView(context);
    tv.setText(strText);
    llay.addView(tv);
    return llay;
  }

I got the output like the above.

I need to show the AlertDialog in full screen / 95% of the Screen size. I need to handle more fields in the Dialog. How do I enable the HorizontalScrollview in the AlertDialog?

解决方案

to get the scrolling behaviour, add a surrounding ScrollView to your layout, which would make your ViewDialogScreen method to this:

private View ViewDialogScreen(String strText) {
    ScrollView scroll = new ScrollView(context);
    scroll.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT));
    LinearLayout llay = new LinearLayout(context);
    llay.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT));
    TextView tv = new TextView(context);
    tv.setText(strText);
    scroll.addView(llay);
    llay.addView(tv);
    return scroll;
}

Now try adding some more fields and it should scroll.
