滚动型不降低Android版本正确显示其内容 [英] ScrollView doesn't display its content properly in lower versions of android

问题描述

您可以看到显示我的滚动视图的软糖一样，和放大器;奇巧，非常真棒：

You can see my scrollview being displayed the same in jellybean, & kitkat, very awesome:

不过，我吃惊地看到同样的事情在较低的版本像2.2，2.3.3

But I am shocked to see the same thing in lower versions like 2.2, 2.3.3

看来，它显示连接到上限与放大器文本的某些部分;屏幕的底部。

It seems that it display some portion of text attached to upper & bottom portion of screen.

顺便说一句，在中间的线是刚刚与灰色的背景textviews。

BTW, The lines in middle are just the textviews with gray background .

您可以看到我的XML code，对不起它有点长code

You can see my xml code, sorry its a little long code

此外，在GraphicalLayout是显示了这样的警告：

Also in GraphicalLayout is shows this warning :

我希望我解释清楚我的问题！

I hope I explained my problem clearly !

寻找一个答案，

在此先感谢

更新：@semsamot回答后，上述警告是消失了，但问题仍然没有解决。

UPDATE: After @semsamot answer the above warning was disappeared, but the problem is still not solved.

对不起，我的上述code太长，但我有我的应用程序的另一个布局显示了同样的问题。

Sorry, my above code was too long but I have another layout in my app displaying the same problem

考虑这个code：

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
android:background="@drawable/stars"
tools:context="com.vivekwarde.numerologyfortune.MyLuckyNumber"
>
<ScrollView 
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:scrollbars="vertical" >

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="vertical" >

        <Button
            android:id="@+id/button1"
            android:layout_width="match_parent"
            android:layout_height="60dp"
            android:textColor="#fff"
            android:gravity="center"
            android:onClick="showDatePickerDialog"
            android:text="Birthdate ?"
            android:background="#4c0000" />

        <TextView
            android:id="@+id/textView1"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_marginTop="15dp"
            android:textColor="#ffffff"
            android:text="Large Text"
            android:textAppearance="?android:attr/textAppearanceLarge" />

        <TextView
            android:id="@+id/textView2"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="Large Text"
            android:textColor="#ffffff"
            android:textAppearance="?android:attr/textAppearanceLarge" />

    </LinearLayout>

</ScrollView>
</RelativeLayout>

如果我显示这个布局简单地将其显示为预计在果冻豆及放大器;奇巧这样的

If I display this layout simply it displays as expected in jelly bean & kitkat like this

不过看到这个输出在2.2和放大器; 2.3.3

But see this output in 2.2 & 2.3.3

为什么的TextView 文本没有按预期正常显示。 ？

Why the text in TextView does not display properly as expected. ?

推荐答案

不要使用浮点值低于1的格式为：.X 相反，使用以下格式：0.X

Don't use float values that lower than 1 in this format: ".x" Instead use this format: "0.x"

如果你改变这些值，你看到的警告消失！

If you change those values you see the warnings disappear!

注意： 还要注意的是在API级别11引入的阿尔法的属性，所以它不会在较低的API（S）工作。

Note: Also note that "alpha" attribute introduced in API Level 11 so it will not work in lower API(s).
