如何设置警告对话框高度和宽度的Andr​​oid？ [英] How to set Alert Dialog height and width in Android?

问题描述

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。

1. 我需要在全屏显示 AlertDialog /屏幕尺寸的95％。


2. 我需要在对话框来处理更多的领域。


3. 如何让 Horizo​​ntalScrollview 在 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.

1. I need to show the AlertDialog in full screen / 95% of the Screen size.
2. I need to handle more fields in the Dialog.
3. 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.
