我必须创建一个搜索栏,我可以通过编程方式更改几乎所有内容.现在我有一个问题是改变拇指和条形尺寸.如果酒吧比拇指更大或尺寸相同,一切都很好,但如果拇指比酒吧大,我不能让它显示整个拇指的正确尺寸.
这是我创建拇指的代码:
public void setSeekBarThumb(int width,int height,int rColor,int gColor,int bColor){
ShapeDrawable thumb = new ShapeDrawable( new ovalShape() );
thumb.setIntrinsicHeight( height );
thumb.setIntrinsicWidth( width );
thumb.setBounds(new Rect(0,width,height));
StateListDrawable states = new StateListDrawable();
states.addState(new int[] {android.R.attr.state_pressed},thumb );//add to the state list with the state pressed
thumb = new ShapeDrawable( new ovalShape() );
thumb.setIntrinsicHeight( height );
thumb.setIntrinsicWidth( width );
thumb.setBounds(new Rect(0,height));
states.addState(new int[] { },thumb );//add to the state list with no state
seekbar.setThumb(states);
seekbar.setThumbOffset(0);
}
继承我创建条形码的代码:
public void setSeekBarProgress(int width,int bColor){
GradientDrawable shape = new GradientDrawable(Orientation.BottOM_TOP,new int[]{Color.WHITE,Color.rgb(rColor,gColor,bColor)});
shape.setCornerRadius(50);
shape.setSize(width,height);
shape.setBounds(0,height);
ClipDrawable clip = new ClipDrawable(shape,Gravity.LEFT,ClipDrawable.HORIZONTAL);
shape = new GradientDrawable(Orientation.BottOM_TOP,getResources().getColor(R.color.DimGray)});
shape.setCornerRadius(50);//change the corners of the rectangle
shape.setSize(width,height);
LayerDrawable mylayer= new LayerDrawable(new Drawable[]{shape,clip,});
seekbar.setProgressDrawable(mylayer);
seekbar.setProgress(50);
}
这是我将所有内容放在一起的代码,我在其中设置了搜索栏的高度:
public MySeekBar(Activity activity,AbsoluteLayout ParentLayout,SeekBarParameters parameters)
{
super(activity.getApplicationContext());
seekbar =(SeekBar)activity.getLayoutInflater().inflate(R.layout.horizontal_seek_bar,ParentLayout,false);
seekbar.setMax(100);
setSeekBarThumb(parameters.widthThumb,parameters.heightThumb,100,0);
setSeekBarProgress(parameters.width,parameters.height,255,69,0);
int drawHeight;
if(parameters.height>parameters.heightThumb) drawHeight=parameters.height;
else drawHeight=parameters.heightThumb;
AbsoluteLayout.LayoutParams params = new AsoluteLayout.LayoutParams(parameters.width,drawHeight,parameters.xPosition,parameters.yPosition);
ParentLayout.addView(seekbar,params);
}
我向以下栏中填充栏的XML代码:
<SeekBar xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:gravity="center"
android:layout_gravity="center"
android:max="100"
android:progress="0"
android:secondaryProgress="0"
android:maxHeight="10000dip"
android:id="@+id/slider"
/>
要更改搜索栏的大小,我使用ParentLayout.addView(seekbar,params).
添加视图时,如果我使用了我想要的高度,那么拇指就会受到割伤.如果我使用拇指的高度,则栏会达到拇指的相同高度. Android将栏的大小调整为我用来添加视图的大小.
我尝试设置GradientDrawable的大小,即带有shape.setSize(宽度,高度)的栏,我也尝试了shape.setBounds(0,height),我尝试使用正确的大小创建另一个图像并添加到LayerDrawable mylayer.但没有任何效果.
通过XML创建时,可以使用paddingTop和paddingBottom将条形图调整到合适的大小.但我不知道如何以编程方式对GradientDrawable执行此操作.
解决方法
好吧,太糟糕没有回应,但我能够自己回答这个问题.答案是使用InsetDrawable.您必须将条形的一个drawable放入InsetDrawable中.
这是代码:
public void setSeekBarProgress(int width,int bColor){
GradientDrawable shape2 = new GradientDrawable(Orientation.BottOM_TOP,bColor)});
shape2.setCornerRadius(50);
ClipDrawable clip = new ClipDrawable(shape2,ClipDrawable.HORIZONTAL);
GradientDrawable shape1 = new GradientDrawable(Orientation.BottOM_TOP,getResources().getColor(R.color.DimGray)});
shape1.setCornerRadius(50);//change the corners of the rectangle
InsetDrawable d1= new InsetDrawable(shape1,5,5);//the padding u want to use
LayerDrawable mylayer = new LayerDrawable(new Drawable[]{d1,clip});
seekbar.setProgressDrawable(mylayer);
seekbar.setProgress(50);
}
我希望这可以帮助其他人解决同样的问题.
