如何以编程方式在线性布局中添加2个textview

Question

大家好，

我从API获得以下字段“Name”和“Skoda”。会有x个这样的项目。根据设计，我应该在下图中显示它们。

所以，我决定以一种名为“childLayout”的线性布局以编程方式创建两个textview，如下所示。

-- RelativeLayout

  -- Linear Layout
        -- TextView  Textview --
  -- Linear Layout 

  -- Linear Layout
        -- TextView  Textview --
  -- Linear Layout      

  -- Linear Layout
        -- TextView  Textview --
  -- Linear Layout 

--RelativeLayout

但我没有得到理想的输出。请帮我解决这个问题。

这是代码：

TextView mType;
TextView mValue;        
for (int i = 0; i < getDetailedDescAL.size(); i++) {

    LinearLayout childLayout = new LinearLayout(
            DetailedCategories.this);

    LinearLayout.LayoutParams linearParams = new LinearLayout.LayoutParams(
            LayoutParams.WRAP_CONTENT,
            LayoutParams.WRAP_CONTENT);
    childLayout.setLayoutParams(linearParams);

    mType = new TextView(DetailedCategories.this);
    mValue = new TextView(DetailedCategories.this);

    mType.setLayoutParams(new TableLayout.LayoutParams(
            LayoutParams.WRAP_CONTENT,
            LayoutParams.WRAP_CONTENT, 1f));
    mValue.setLayoutParams(new TableLayout.LayoutParams(
            LayoutParams.WRAP_CONTENT,
            LayoutParams.WRAP_CONTENT, 1f));

    mType.setTextSize(17);
    mType.setPadding(5, 3, 0, 3);
    mType.setTypeface(Typeface.DEFAULT_BOLD);
    mType.setGravity(Gravity.LEFT | Gravity.CENTER);

    mValue.setTextSize(16);
    mValue.setPadding(5, 3, 0, 3);
    mValue.setTypeface(null, Typeface.ITALIC);
    mValue.setGravity(Gravity.LEFT | Gravity.CENTER);

    mType.setText(getDetailedDescAL.get(i).getmPropertyType());
    mValue.setText(getDetailedDescAL.get(i).getmPropertyValue());

    childLayout.addView(mValue, 0);
    childLayout.addView(mType, 0);

    RelativeLayout.LayoutParams relativeParams = 
        new RelativeLayout.LayoutParams(
            LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT);
    relativeParams.addRule(RelativeLayout.BELOW);
    Details.addView(childLayout, relativeParams);

    // Details is the relative layout declared in XML

}

输出结果为：

看起来文字视图是最重要的。如何解决这个问题。

Answer 1

替换RelativeLayout的{​​{1}}并将所有LinearLayout添加到该TextView's。 别忘了android:orientation="vertical"

中的LinearLayout

Answer 2

for(int j=0;j<30;j++)
            {

                 LinearLayout childLayout = new LinearLayout(
                            MainActivity.this);

                    LinearLayout.LayoutParams linearParams = new LinearLayout.LayoutParams(
                            LayoutParams.WRAP_CONTENT,
                            LayoutParams.WRAP_CONTENT);
                    childLayout.setLayoutParams(linearParams);

                    TextView mType = new TextView(MainActivity.this);
                    TextView mValue = new TextView(MainActivity.this);

                    mType.setLayoutParams(new TableLayout.LayoutParams(
                            LayoutParams.WRAP_CONTENT,
                            LayoutParams.WRAP_CONTENT, 1f));
                    mValue.setLayoutParams(new TableLayout.LayoutParams(
                            LayoutParams.WRAP_CONTENT,
                            LayoutParams.WRAP_CONTENT, 1f));

                    mType.setTextSize(17);
                    mType.setPadding(5, 3, 0, 3);
                    mType.setTypeface(Typeface.DEFAULT_BOLD);
                    mType.setGravity(Gravity.LEFT | Gravity.CENTER);

                    mValue.setTextSize(16);
                    mValue.setPadding(5, 3, 0, 3);
                    mValue.setTypeface(null, Typeface.ITALIC);
                    mValue.setGravity(Gravity.LEFT | Gravity.CENTER);

                    mType.setText("111");
                    mValue.setText("111");

                    childLayout.addView(mValue, 0);
                    childLayout.addView(mType, 0);

                    linear.addView(childLayout);
            }

Answer 3

将相对布局更改为线性布局并已解决

Answer 4

JFI，你为什么不简单地使用ListView。在帖子中，您提到项目数量未知。因此，可能存在这样的情况：您将拥有的项目数量超过可见屏幕空间的数量。 Listview将为您处理滚动。

P.S。：在这里，使用scrollView

而不是Relative或LinearLayout
