Android:文本视图的最后一行被切断 [英] Android: Last line of textview cut off
本文介绍了Android:文本视图的最后一行被切断的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我有一个水平的 LinearLayout，其中包含一个 TextView，紧接着是一个 Spinner.此 LinearLayout 在包含在 RelativeLayout 中的固定垂直 LinearLayout 中动态膨胀多次.
I have a horizontal LinearLayout containing a TextView followed by a Spinner next to it. This LinearLayout is dynamically inflated multiple times in a fixed vertical LinearLayout contained within a RelativeLayout.
问题是，由于我从 Theme.light 切换到 Theme.holo.light，TextView 的最后一行被剪掉了一半.当动态文本很长并且跨越多行时会发生这种情况.
The problem is that since I switched from Theme.light to Theme.holo.light, the last line of the TextView gets cut in half. This happens when the dynamic text is long and spans more than one row.
我已经能够通过向包含 TextView 和 Spinner 的水平 LinearLayout 添加底部填充来解决这个问题.
I have been able to fix this by adding bottom padding to the horizontal LinearLayout containing the TextView and Spinner.
这感觉不像是一种修复，而更像是一种黑客攻击.有人可以就如何正确解决此问题给我一些建议吗?
This does not feel like a fix, but more of a hack. Can someone please give me some advice on how to properly fix this?
我还阅读了一些其他问题，但似乎都没有帮助.
I have also read some other questions, but none seem to help.
水平线性布局:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="horizontal">
<TextView
android:id="@+id/textView1"
android:layout_width="150dp"
android:layout_height="wrap_content"
android:layout_marginRight="20dp"
android:text="TextView"/>
<Spinner
android:id="@+id/spinner1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"/>
</LinearLayout>
相对布局，上面的布局在 id ll2_7 的线性布局中动态膨胀:
Relative layout where above layout is dynamically inflated at Linear Layout with id ll2_7:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<ScrollView
android:id="@+id/scrollView"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_above="@+id/relLayoutButtonNext"
android:layout_below="@id/textView1" >
<RelativeLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:paddingBottom="20dp"
android:paddingLeft="10dp"
android:paddingRight="10dp"
android:paddingTop="10dp" >
<TextView
android:id="@+id/textView10"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:paddingRight="30dp"
android:text="2.7" />
<TextView
android:id="@+id/textView11"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginBottom="10dp"
android:layout_toRightOf="@id/textView10"
android:text="@string/question2_7" />
<LinearLayout
android:id="@+id/ll2_7"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignLeft="@+id/textView11"
android:layout_below="@+id/textView11"
android:orientation="vertical" android:layout_marginBottom="20dp">
</LinearLayout>
</RelativeLayout>
</ScrollView>
</RelativeLayout>

推荐答案
我遇到了与屏幕截图所示相同的中断问题.它是由水平LinearLayout 中的基线对齐引起的.TextView 和 Spinner 由于字体大小不同而具有不同的基线.要解决此问题，需要通过设置禁用基线对齐:
I've encountered the same cut-off issue as shown at the screenshot. It is caused by the baseline alignment in the horizontal LinearLayout. TextView and Spinner have different baselines due to font size difference. To fix the issue it is needed to disable baseline alignment for the layout by setting:
android:baselineAligned="false"
或在代码中:
layout.setBaselineAligned(false);
