Question

我正在开发一个音乐播放器，我正在使用铃声切割器。我在Github上得到ringdroid的引用。但是当我在我的解决方案中包含一个布局时，它无法正常工作。工具栏不可见，文本框如果下半部分。 Here is the screenshot ..看起来应该是什么以及将要发生什么。下面是哪个问题的布局。

And here is the desired result

Answer 1

将您的 EditText - start_label and end_label高度从31dp更改为View尺寸（此处假设为45dp）至：

<EditText android:id="@+id/endtext"
    android:textSize="16sp"
    android:inputType="number|numberDecimal"
    android:layout_width="70dip"
    android:layout_height="45dip"  //<---here
    android:layout_marginLeft="10dip"
    android:gravity="center"
    android:contentDescription="@string/end_label" />

Answer 2

Do not use AbsoluteLayout, it is deprecated. Try RelativeLayout instead
