slidingdrawer动画速度
作者:互联网
我是Android编程的新手,并且会溢出堆栈,因此需要降低我的应用程序中SlidingDrawer的动画速度.
我已经像这样子化了SlidingDrawer:
import android.content.Context;
import android.util.AttributeSet;
import android.view.View;
import android.widget.SlidingDrawer;
public class WrappingSlidingDrawer extends SlidingDrawer {
public WrappingSlidingDrawer(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
int orientation = attrs.getAttributeIntValue("android", "orientation", ORIENTATION_VERTICAL);
mTopOffset = attrs.getAttributeIntValue("android", "topOffset", 0);
mVertical = (orientation == SlidingDrawer.ORIENTATION_VERTICAL);
}
public WrappingSlidingDrawer(Context context, AttributeSet attrs) {
super(context, attrs);
int orientation = attrs.getAttributeIntValue("android", "orientation", ORIENTATION_VERTICAL);
mTopOffset = attrs.getAttributeIntValue("android", "topOffset", 0);
mVertical = (orientation == SlidingDrawer.ORIENTATION_VERTICAL);
}
@Override
protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
int widthSpecMode = MeasureSpec.getMode(widthMeasureSpec);
int widthSpecSize = MeasureSpec.getSize(widthMeasureSpec);
int heightSpecMode = MeasureSpec.getMode(heightMeasureSpec);
int heightSpecSize = MeasureSpec.getSize(heightMeasureSpec);
if (widthSpecMode == MeasureSpec.UNSPECIFIED || heightSpecMode == MeasureSpec.UNSPECIFIED) {
throw new RuntimeException("SlidingDrawer cannot have UNSPECIFIED dimensions");
}
final View handle = getHandle();
final View content = getContent();
measureChild(handle, widthMeasureSpec, heightMeasureSpec);
if (mVertical) {
int height = heightSpecSize - handle.getMeasuredHeight() - mTopOffset;
content.measure(widthMeasureSpec, MeasureSpec.makeMeasureSpec(height, heightSpecMode));
heightSpecSize = handle.getMeasuredHeight() + mTopOffset + content.getMeasuredHeight();
widthSpecSize = content.getMeasuredWidth();
if (handle.getMeasuredWidth() > widthSpecSize) widthSpecSize = handle.getMeasuredWidth();
}
else {
int width = widthSpecSize - handle.getMeasuredWidth() - mTopOffset;
getContent().measure(MeasureSpec.makeMeasureSpec(width, widthSpecMode), heightMeasureSpec);
widthSpecSize = handle.getMeasuredWidth() + mTopOffset + content.getMeasuredWidth();
heightSpecSize = content.getMeasuredHeight();
if (handle.getMeasuredHeight() > heightSpecSize) heightSpecSize = handle.getMeasuredHeight();
}
setMeasuredDimension(widthSpecSize, heightSpecSize);
}
private boolean mVertical;
private int mTopOffset;
}
我找到了以下链接:How to change animation velocity on SlidingDrawer,它说我可以找到替代实现,或者复制源代码并对其进行修改.
我在自己的项目中创建了SlidingDrawer.java,并粘贴了here的代码,但是有错误.有几行引用了R.styleable.SlidingDrawer,例如
TypedArray a = context.obtainStyledAttributes(attrs,
R.styleable.SlidingDrawer, defStyle, 0);
Eclipse无法解决的问题.
还有四个Eclipse无法解析的成员变量(mTop,mBottom,mLeft和mRight).
如何使Eclipse查找这些资源/变量?然后,我将能够编辑一些变量以使动画速度变慢,对吗?
解决方法:
我相信R.styleable已从sdk中删除,但是您可以编写自己的代码,类似的东西应该可以工作
在values文件夹中创建一个xml文件
<?xml version="1.0" encoding="UTF-8"?>
<resources>
<declare-styleable name="MySlider">
<attr name = "SlidingDrawer_orientation" format="integer"/>
<attr name = "SlidingDrawer_bottomOffset" format = "dimension"/>
<attr name = "SlidingDrawer_topOffset" format = "dimension"/>
<attr name = "SlidingDrawer_allowSingleTap" format = "boolean"/>
<attr name = "SlidingDrawer_animateOnClick" format = "boolean"/>
<attr name = "SlidingDrawer_handle" format = "reference"/>
<attr name = "SlidingDrawer_content" format = "reference"/>
</declare-styleable>
</resources>
然后在滑块类中,您可以引用xml文件
TypedArray a = context.obtainStyledAttributes(attrs, R.styleable.MySlider, defStyle, 0);
int orientation = a.getInt(R.styleable.MySlider_SlidingDrawer_orientation, ORIENTATION_VERTICAL);
//...etc. ...
我也在扩展slidedrawer类,这对我有用.
