SeekBar 指针不在中心 Android Studio Java

Question

I am making a SeekBar in my Android Java application for the first time, but the slider circle is not in the middle of the line as I would expect, but a little above it. I can't figure out why this is the case.

There is an image of the slider at http://i.stack.imgur.com/AAGkM.jpg

My layout for the slider is:

    <SeekBar
    android:layout_width="match_parent"
    android:id="@+id/seekBar"
    android:layout_height="0dp"
    android:layout_weight="0.5"
    android:background="#ffff4007"
    android:progress="0"
    android:max="100"/>

Answer 1

您可以发布您的布局代码以更好地帮助您，也许您可​​以试试这个

android:gravity="center"

Answer 2

要做到这一点，请使用 android:progress=0 在 java 中使用 Seekbar.setmax(to set maxm value..as integer);
