如何创建一个可滚动布局 [英] how to create a scrollable layout

问题描述

我试图让一个布局动态，它应该是滚动的，因为我不知道我应该有多少文本字段和编辑文本字段绘制。画面如下图所示。

 的LinearLayout布局=新的LinearLayout（本）;
            layout.setOrientation（LinearLayout.VERTICAL）;
            layout.setLayoutParams（新的LayoutParams（LayoutParams.WRAP_CONTENT，LayoutParams.WRAP_CONTENT））;
            的setContentView（布局）;
 

解决方案

在滚动型附上你的父母布局（LinearLayout中或RelativeLayout的）。这就是所有你需要解决这个问题。

 滚动型滚动=新的滚动型（本）;
scroll.setLayoutParams（新的LayoutParams（LayoutParams.FILL_PARENT，
      LayoutParams.FILL_PARENT））;的LinearLayout布局=新的LinearLayout（本）;
layout.setOrientation（LinearLayout.VERTICAL）;
layout.setLayoutParams（新的LayoutParams（LayoutParams.WRAP_CONTENT，
      LayoutParams.WRAP_CONTENT））;scroll.addView（布局，
      新的LayoutParams（LayoutParams.FILL_PARENT，LayoutParams.WRAP_CONTENT））;的setContentView（滚动）;
 

Hi I am trying to make a layout dynamically and it should be scrollable because I will not know how many text fields and edit text fields I should draw. The picture is shown below.

            LinearLayout layout=new LinearLayout(this);
            layout.setOrientation(LinearLayout.VERTICAL);
            layout.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT,      LayoutParams.WRAP_CONTENT)); 
            setContentView(layout);

解决方案

Enclose your parent layout (LinearLayout or RelativeLayout) in a ScrollView. Thats all you need to fix this.

ScrollView scroll = new ScrollView(this);
scroll.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT,
      LayoutParams.FILL_PARENT));

LinearLayout layout=new LinearLayout(this);
layout.setOrientation(LinearLayout.VERTICAL);
layout.setLayoutParams(new LayoutParams(LayoutParams.WRAP_CONTENT,
      LayoutParams.WRAP_CONTENT)); 

scroll.addView(layout,
      new LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT));

setContentView(scroll);
