以编程方式更改搜索栏的大小但不能使拇指大于条形

Question

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, 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, 0, width, 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 height, int rColor, int gColor, 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, 0, width, height);
        ClipDrawable clip = new ClipDrawable(shape, Gravity.LEFT,ClipDrawable.HORIZONTAL);

        shape = new GradientDrawable(Orientation.BOTTOM_TOP, new int[]{Color.WHITE, getResources().getColor(R.color.DimGray)});
        shape.setCornerRadius(50);//change the corners of the rectangle 
        shape.setSize(width, height);
        shape.setBounds(0, 0, 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,0,100,0);
         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hape.setSize(width, height)尝试使用s设置GradientDrawable的大小,我也尝试了shape.setBounds(0, 0, width, height),我尝试创建另一个具有正确大小的图像并添加到LayerDrawable mylayer.但没有任何效果.

通过XML创建时,可以使用paddingTop并使paddingBottom条形图达到正确的大小.但我不知道如何以编程方式对GradientDrawable执行此操作.

well, too bad there were no responses but i was able to answer the question myself. The answer is to use InsetDrawable. You have to put the one of the drawables of the bar into a InsetDrawable.

Thats the code:

  public void setSeekBarProgress(int width, int height, int rColor, int gColor, int bColor){
        GradientDrawable shape2 = new GradientDrawable(Orientation.BOTTOM_TOP, new int[]{Color.WHITE,Color.rgb(rColor, gColor, bColor)});
        shape2.setCornerRadius(50);                     
        ClipDrawable clip = new ClipDrawable(shape2, Gravity.LEFT,ClipDrawable.HORIZONTAL);

        GradientDrawable shape1 = new GradientDrawable(Orientation.BOTTOM_TOP, new int[]{Color.WHITE, getResources().getColor(R.color.DimGray)});
        shape1.setCornerRadius(50);//change the corners of the rectangle    
        InsetDrawable d1=  new InsetDrawable(shape1,5,5,5,5);//the padding u want to use        


        LayerDrawable mylayer = new LayerDrawable(new Drawable[]{d1,clip});


        seekbar.setProgressDrawable(mylayer); 

        seekbar.setProgress(50);

  }

I hope this can help someone else with the same problem.
