在Android 6.0棉花糖停止显示垂直搜索栏拇指 [英] Android 6.0 Marshmallow stops showing Vertical SeekBar thumb
问题描述
我一直在使用这个基本的包装围绕一个搜索栏,但发现它隐藏了拇指,或做一些事情一样时髦让白在白色背景上,棉花糖下。
我使用了ASBlankActivity向导创建一个项目来说明这一点,变着法子除了这里描述是什么,从默认值。左边是棒棒糖,同样code是根据棉花糖权运行的:
有一个自定义的水平搜索栏,以测试是否有一个普遍的问题定制他们,这不存在。在左侧的第一垂直一只没有风格,这是细$ P $对 - 棉花糖但不另外,中央一显式使用Widget.Material.Light.SeekBar样式来测试如果默认某种程度上没有被拾起和最后一个给出了一个重大线索,因为它使用旧的Widget.Holo.SeekBar风格的地方它会出现,尽管看起来像它在几年前就出来了。
下面是这个布局:

只需使用普通的搜索栏,并采用Android:旋转=270,帮助我
<搜索栏

I've been using this basic wrapper around a SeekBar but find it hides the thumb, or does something funky like make it white on a white background, under Marshmallow.
I used the AS "BlankActivity" wizard to create a project to illustrate this, changing nothing except what is described here, from the defaults. On the left is Lollipop, and the same code is running on the right under Marshmallow:
There is a custom horizontal SeekBar to test if there was a general problem customizing them, which there isn't. The first vertical one on the left has no style, which is fine pre-Marshmallow but not otherwise, the central one explicity uses the Widget.Material.Light.SeekBar style to test if the default somehow wasn't being picked up, and the last one gives a big clue because it uses the old Widget.Holo.SeekBar style where it then appears, albeit looking like it came out a few years ago.
Here's the layout for this:
<?xml version="1.0" encoding="utf-8"?>
<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:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
android:paddingBottom="@dimen/activity_vertical_margin"
tools:context=".MainActivity"
>
<com.otamate.seekbarmarshbug.CustomSeekBar
android:id="@+id/seekBarCustom"
android:layout_width="match_parent"
android:layout_height="wrap_content"
/>
<com.otamate.seekbarmarshbug.VerticalSeekBar
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_below="@+id/seekBarCustom"
/>
<com.otamate.seekbarmarshbug.VerticalSeekBar
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:gravity="center_horizontal"
android:layout_below="@+id/seekBarCustom"
android:layout_centerHorizontal="true"
style="@android:style/Widget.Material.Light.SeekBar"
/>
<com.otamate.seekbarmarshbug.VerticalSeekBar
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_alignParentRight="true"
android:layout_below="@+id/seekBarCustom"
style="@android:style/Widget.Holo.SeekBar"
/>
</RelativeLayout>
The CustomSeekBar:
package com.otamate.seekbarmarshbug;
import android.content.Context;
import android.util.AttributeSet;
import android.widget.SeekBar;
public class CustomSeekBar extends SeekBar {
public CustomSeekBar(Context context) {
super(context);
}
public CustomSeekBar(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
}
public CustomSeekBar(Context context, AttributeSet attrs) {
super(context, attrs);
}
}
and the VerticalSeekBar:
package com.otamate.seekbarmarshbug;
import android.content.Context;
import android.graphics.Canvas;
import android.util.AttributeSet;
import android.view.MotionEvent;
import android.widget.SeekBar;
public class VerticalSeekBar extends SeekBar {
public VerticalSeekBar(Context context) {
super(context);
}
public VerticalSeekBar(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
}
public VerticalSeekBar(Context context, AttributeSet attrs) {
super(context, attrs);
}
protected void onSizeChanged(int w, int h, int oldw, int oldh) {
super.onSizeChanged(h, w, oldh, oldw);
}
@Override
protected synchronized void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
super.onMeasure(heightMeasureSpec, widthMeasureSpec);
setMeasuredDimension(getMeasuredHeight(), getMeasuredWidth());
}
protected void onDraw(Canvas c) {
c.rotate(-90);
c.translate(-getHeight(), 0);
super.onDraw(c);
}
@Override
public boolean onTouchEvent(MotionEvent event) {
if (!isEnabled()) {
return false;
}
switch (event.getAction()) {
case MotionEvent.ACTION_DOWN:
case MotionEvent.ACTION_MOVE:
case MotionEvent.ACTION_UP:
setProgress(getMax() - (int) (getMax() * event.getY() / getHeight()));
onSizeChanged(getWidth(), getHeight(), 0, 0);
break;
case MotionEvent.ACTION_CANCEL:
break;
}
return true;
}
}
Just use a normal SeekBar and use android:rotation="270" that helped for me.
<SeekBar
android:id="@+id/seekBar"
android:rotation="270"
/>
